SmartAccess
With a unique secure code, the SmartAccess key fob automatically enables you to unlock the vehicle’s front doors and its available power rear door without removing the key fob from your purse, pocket or briefcase. As soon as the sensors detect your SmartAccess key fob, the door unlocks when you touch the handle. SmartAccess even activates the lighting entry system to illuminate your points of entry from the exterior puddle lights to the interior lights. Once inside, it just takes a push of the button to start the engine.
Adaptive Front Lighting System
A particularly useful feature when driving at night or during inclement weather, the available Adaptive Front Lighting System is designed to estimate and illuminate where the RX 450h will be in three seconds based on vehicle speed and steering angle. In a left turn, the left headlamp can rotate up to 15 degrees, and in a right turn, the right headlamp can rotate up to 10 degrees.
Intelligent High-Beam Headlamps
Helping to provide greater visibility to the driver without compromising the visibility of other drivers on the road, the available intelligent high-beam headlamps on the RX 450h operate in high-beam mode until a camera mounted in the back of the rearview mirror detects an oncoming vehicle or other vehicles traveling closely ahead. The headlamps will then automatically enter into low-beam mode until vehicles are no longer detected ahead.
Wide-view Side Monitor
To assist you with parking and when negotiating narrow passes, an available Wide-view Side Monitor camera built into the passenger-side mirror can display an overhead view to the right of the RX 450h at slow speeds or when in reverse.
Backup Camera
Backing out of tight spaces and avoiding mishaps is much easier with the available backup camera . Using a tiny camera located above the rear license plate to capture a view of what’s behind the RX 450h when placed in reverse, the camera’s view is displayed in full color on a screen within the rearview mirror or on the available Navigation System screen.
Power Rear Door
The available power rear door of the RX 450h offers remote, keyless access to the rear storage area. The lift-gate can be raised and lowered from inside the vehicle by using a switch or remotely with the included key fob.
Next-Generation Design
With sharp dramatic lines and a distinctive trapezoid grille, the 2012 RX 450h shares many design cues with the current Lexus sedans. It also features standard 18-inch five-spoke alloy wheels and can be outfitted with available 19-inch split-five-spoke alloy wheels that are exclusive to the RX 450h.
Dynamic Radar Cruise Control
This advanced system available on the RX 450h with all-wheel drive is designed to adapt to traffic congestion by using radar technology to help maintain a pre-set following distance from the vehicle traveling in front of you. If you get too close, the throttle is automatically reduced and brakes are applied. Once the road clears, the RX 450h will return to its pre-set speed.
Intuitive Parking Assist
Available sensors integrated into the front and rear bumpers help detect how close your vehicle is to surrounding objects. Audible warning tones and graphics in the multi-information console display and an available navigation screen assist the driver in knowing the location and proximity of objects around the vehicle.
Rear Spoiler
The rear spoiler on the RX 450h diffuses the air flowing over the back of the vehicle, decreasing turbulence, and contributing to a remarkably low coefficient of drag and excellent fuel efficiency. Beyond these primary functions, the spoiler also houses an additional rear taillamp and conceals the radio antenna and rear-window wiper for a sleeker appearance from behind.
Interior
Voice-Activated HDD Navigation System
The available voice-activated Hard Disk Drive (HDD) Navigation System on the RX 450h utilizes a high–resolution eight-inch LCD placed close to eye level to help you remain focused on the road. An intuitive interface was also developed to display a linear progression of your commands as you use different functions within the system. Featuring voice–command technology, you can search for destinations using your regular speaking voice and more natural phrasing. “Show me Chinese restaurants,” from the destination menu, for example, will display locations in your immediate vicinity. And once a destination is selected, the system will calculate up to three different routes and provide audible and visual directions as you drive.
The system also features NavTraffic™, which can provide real-time traffic reports on specific highways or routes and reroute you around congestion. And, for the first time on a utility vehicle, NavWeather™ , which can provide real-time weather reports for specific cities and even automatically alert you of severe weather. A complimentary 90-day trial subscription to SiriusXM services is included.
Heads-up Display
The available Heads-up Display system on the RX 450h AWD can project simple navigation directions, audio information and vehicle speed onto the windshield in front of you, so you can spend more time focused on the road ahead. Unlike other Heads-up Display systems that provide intersection names, requiring the driver to locate street signs, the navigation directions on the system in the RX 450h are provided using a countdown of the remaining distance before an action needs to be taken and an animated arrow that guides you intuitively through turns.
Mark Levinson® Premium Surround Sound Audio System and Lexus Premium
Surround Sound Audio System
The placement and angle of every speaker and the careful consideration of every component were essential in the development of the Lexus Premium Audio System in the RX 450h. The result is a system that immerses the driver and passenger in remarkably vivid sound. For the true audiophile, an available 15-speaker Mark Levinson® Premium Surround Sound Audio System uses 7.1-channel architecture and 330 watts of maximum power, all channels driven at less than 0.1% THD, 20–20,000 Hz, to deliver a virtual sweet spot of sound that encompasses the entire cabin in sound quality that was once only reserved for six-figure home-audio systems.
Dual-Screen Rear-Seat Entertainment System
An available dual-screen Rear-Seat Entertainment System allows the left and right rear-seat passengers to watch or listen to the audio or video source of their choosing through independent A/V inputs. With seven-inch LCD screens located behind the driver’s and front passenger’s headrests, each system features a pair of wireless headphones and can be used as a DVD player, audio player or game console via audio and video input jacks. For your convenience, a single remote controls both systems, and a standard electrical outlet is also provided.
Heated and Ventilated Front Seats
Whatever the weather, the available heated and ventilated front seats will be appreciated. On cold days, the seats can be heated to one of three settings through zones distributed throughout the seatbacks and lower seat cushions. For optimal comfort, the amount of heat provided varies by the location of the zone (your thighs get more heat than your upper back, for instance). In warmer weather, you can select from three ventilation settings to have fans housed inside the seatbacks and cushions circulate air through perforations in the leather trim.
Multi-Adjustable Rear Seats
The RX 450h’s rear seat is divided into three seating areas via a 40/20/40 split. To provide optimal comfort to your rear-seat passengers, each seating area can be individually adjusted in a variety of ways. For instance, seatbacks can be reclined up to 12 degrees. A leather-trimmed center armrest can be folded down for the outboard passengers. And each seat can slide independently, providing additional legroom or cargo space. For your convenience, there are also multiple ways to fold the rear seats flat: Ergonomic levers are located on sides of the outboard seats, and remote levers are located on either side of the cargo area.
Adaptable Cargo Area
The folding 40/20/40-split rear seats can slide forward or backward with little effort. Also included is a two-part tonneau cover which conceals valuables or loose gear when the rear hatch is closed and separates when the rear hatch is opened, enabling you to access items in the cargo area without retracting the cover. For added convenience, the rear seats fold effortlessly with remote levers on either side of the rear-door opening.
Multi-Information Display with Steering-Wheel Switchgear
The multi-information display on the RX 450h uses white OLED (Organic Light Emitting Diode) technology. Unlike conventional TFT displays that require backlighting, the OLED display on the RX 450h offers superior visibility through vibrant self-luminescent characters sharply displayed on a high-contrast black background and ensures readability from an angle wide enough for even the front passenger to read. A multi-information switch on the steering wheel enables the driver to operate the available Intuitive Park Assist, Adaptive Front Lighting System (AFS) and to select an array of other personalized settings without removing your hands from the steering wheel.
HomeLink® Remote Control
The HomeLink® universal transceiver allows you to control up to three compatible remote devices—the garage door, your entry gate, even the living room lights—all with the touch of a button.
Courtesy Lamps
From exterior puddle lamps to the illuminated vehicle Power button, it’s easy to navigate the interior of an RX 450h. Overhead spotlamps are located above the front and rear seating areas, as well as in the driver and front-passenger footwell areas.
Performance
Hybrid Powertrain
The 2012 RX 450h features a 3.5-liter V6 Atkinson-cycle engine that works differently than conventional engines to convert more of the energy generated during combustion into mechanical energy. It also features a hybrid battery that is lighter and more compact than that found in the previous-generation RX Hybrid. As a result of these advancements, the RX 450h produces a combined 295 horsepower and provides instantaneous torque when you need it most.
The RX 450h includes innovative systems that contribute to efficiency and a fuel-economy rating that surpasses that of an average four-cylinder midsize sedan. One of these systems is an Exhaust Heat-Recovery system that captures a portion of the exhaust gasses generated during startup and uses them to help warm the gasoline engine. On cold days, this can significantly reduce the time it takes for the RX 450h to reach a point where it can shut off the gasoline engine and function on battery power alone, by up to 15 minutes in some cases.
ECO Mode
To encourage a more efficient driving style, the RX 450h features an ECO mode that modifies the air conditioning’s load on the engine and regulates the throttle response for more efficient acceleration. Under certain conditions, the RX 450h can be operated in EV mode where it can function on battery power alone—a particularly useful feature when driving in residential areas at night and in enclosed areas like parking garages.
ECVT Automatic Transmission with Intelligent Shift Control System
The Electronically controlled Continuously Variable Transmission with intelligence (ECVT-i) on the RX 450h uses power from the engine and hybrid battery to drive the front wheels with peak efficiency. And, because it doesn’t have gears like a traditional transmission, shift shock is eliminated for smoother acceleration. The RX 450h is also the first hybrid utility vehicle to feature an Electronic continuously Variable Transmission with Intelligent Shift Control system. Enabling the driver to upshift or downshift by nudging the gearshift forward or backward, it provides greater responsiveness and maneuverability in different driving conditions.
Part-time All-Wheel Drive (AWD)
When accelerating from a stop or if front-wheel slippage is detected, the all-wheel drive system on the RX 450h is designed to electrically power the rear wheels, helping to provide additional drive force to propel the vehicle forward.
Superb Handling
Stiff unibody construction and front and rear stabilizer bars reduce body lean in corners and deliver overall ride quality like that of a luxury sedan. For greater agility and dynamic handling, the RX 450h features a low center of gravity courtesy of a low powertrain, a fully independent MacPherson strut front suspension and a completely unique double-wishbone rear suspension that took 30 separate tuning sessions to develop. The system not only helps to improve roadhandling grip, it also intrudes less into the cargo area, freeing up floor space.
Speed-Sensing Electronic Power Steering with Steering Torque Assist
A progressive power-assisted rack-and-pinion steering system on the RX 450h senses the vehicle speed and automatically delivers the appropriate level of steering assistance. The result is greater fuel efficiency and steering feel.
The RX 450h also features a steering torque assist system that can sense and respond when the vehicle is braking on a road with different levels of friction. For example, when braking with the left wheels on asphalt and the right wheels on snow, vehicles tend to deflect toward the higher-friction side due to the difference between the braking forces. By adding steering torque to balance the difference, vehicle control is enhanced.
Regenerative Braking
The RX 450h ensures its batteries remain properly charged through regenerative braking. Energy that’s normally lost as heat during braking, coasting or deceleration is captured as electrical power, which is then used to recharge the batteries. It’s one more reason why the RX 450h never needs to be plugged in.
Ventilated Disc Brakes
The RX 450h utilizes Actively Safe features for better braking and control. Ventilated front disc brakes have special ducts inside to better dissipate heat, which helps improve braking performance. For greater brake feel and further effectiveness, a twin-piston caliper design is used on the front brakes, and the rotor size has been increased on the rear brakes.
Safety & Security
Class-leading 10-Airbag System
The RX 450h leads its class with a total of 10 airbags . The Supplemental Restraint System (SRS) in the RX 450h includes front seat-mounted side-impact airbags that provide a larger protection area than conventional side airbags. A driver’s dual-stage airbag deploys at one of two speeds, depending on factors like crash severity and driver’s seat-track position. And the front passenger’s dual-stage, twin-chamber airbag uses occupant weight and crash-severity sensors to monitor its deployment. Also included are front and rear roll-sensing side curtain airbags, outboard rear seat-mounted airbags and driver’s and front passenger’s knee airbags.
Vehicle Stability Features
Utilizing a sophisticated network of sensors that monitor everything from speed, to steering, to braking, the Vehicle Dynamics Integrated Management (VDIM) system can anticipate a loss of traction and correct it before it occurs. When VDIM detects a potential loss of traction, it seamlessly integrates steering, braking, Traction Control (TRAC) and Vehicle Stability Control (VSC) to help the driver maintain control. All within a fraction of a second. The system is so advanced it can even sense if the wheels are driving on different surfaces—a wet road on the left and an icy shoulder on the right, for instance—and add steering torque to either side to help account for the difference.
Active Front Headrests
The RX 450h comes equipped with active front headrests for the driver and front passenger. In certain low-speed rear-end collisions, the active front headrests use the force of the occupant’s body against the seatback to move the headrest diagonally upward and forward instantaneously to help support the head, thereby helping to reduce the severity of whiplash-type injuries.
Direct Tire Pressure Monitor System
The direct Tire Pressure Monitor System in the RX 450h constantly monitors the air pressure of all tires, including the spare. When it senses that tire pressure is critically low, it alerts the driver with an indicator light.
ABS with Brake Assist
Stepping on the brake pedal quickly and forcefully during an emergency situation activates the four-sensor, four-channel Anti-lock Braking System (ABS) with Brake Assist . Once activated, the system provides supplemental braking power if the driver does not apply enough pressure to the pedal. And to help provide even greater control, Electronic Brakeforce Distribution (EBD) modulates the amount of fluid pressure distributed to the front and rear brakes.
Reinforced Body
The RX 450h is built with a welded-steel unibody frame, strong box-section, side-impact door beams and impact-dissipating front and rear crumple zones. As a result of information gathered during the 233 crash tests performed on the RX during development, reinforcements to the roof, roof header, floor, crossmembers and the A-pillar help provide increased buckling strength and enhanced load sustainability when buckled, helping to reduce the deformation of the cabin in the event of certain collisions.
Smart Stop Technology
For additional peace of mind, this safety feature is designed to automatically reduce engine power when the driver is pressing down the accelerator and brake pedals at the same time under certain conditions. When the brake pedal is released, the Smart Stop Technology disengages. The feature does not engage if the brake pedal is pressed before the accelerator.
