Safety





Class-Leading 10-Airbag System
The class-leading Supplemental Restraint System (SRS) in the RX includes front seat-mounted side-impact airbags [1] that provide a larger protection area than conventional side airbags. A driver’s dual-stage airbag deploys at one of two speeds, depending on things 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.

[1] All the airbag (AB) systems are Supplemental Restraint Systems. All ABs (if installed) are designed to inflate only under certain conditions and in certain types of severe collisions: frontal and knee ABs typically inflate in frontal collisions; side and side curtain ABs in side collisions; Roll-Sensing Curtain ABs at a severe tilt degree, roll or lateral G-force. In all other accidents, the ABs will not inflate. To decrease the risk of injury from an inflating AB, always wear seatbelts, sit upright in the middle of the seat as far back as possible and do not lean against the door. Do not put objects in front of an AB or around the seatback. Do not use a rearward-facing child seat in any front passenger seat. The force of an inflating AB may cause serious injury or death. Please see your Owner’s Manual for further information/warnings.

Vehicle Stability Features
Utilizing a sophisticated network of sensors that monitor everything from speed, to steering, to braking, the available Vehicle Dynamics Integrated Management (VDIM) [1] 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) [1] 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.

[1]Vehicle Stability Control (VSC) and Vehicle Dynamics Integrated Management (VDIM) are electronic systems designed to help the driver maintain vehicle control under adverse conditions. They are not substitutes for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether VSC and VDIM will be effective in preventing a loss of control. Please see your Owner's Manual for further details.

Active Front Headrests
The RX comes equipped with active front headrests [1] 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 possibility of whiplash.

[1] Active headrests can help prevent or limit the extent of whiplash in certain types of rear-end collisions.

Pre-Collision System
A front-mounted millimeter-wave radar sensor on the available Pre-Collision System (PCS) [1] constantly monitors the distance and closing speed of a vehicle traveling ahead. When the system's computer determines that a frontal collision is unavoidable, the PCS preemptively tightens the front seatbelts and preps the Brake Assist [2] for increased braking pressure the moment the driver steps on the brake pedal.
[1] The Pre-Collision System is designed to help reduce the crash speed and damage in certain frontal collisions only. It is not a collision-avoidance system and is not a substitute for safe and attentive driving. System effectiveness depends on many factors, such as speed, driver input and road conditions. Please see your Owner's Manual for further information.
[2] Brake Assist is designed to help the driver take full advantage of the benefits of ABS. It is not a substitute for safe driving practices. Braking effectiveness also depends on proper brake-system maintenance and tire and road conditions.

Direct Tire Pressure Monitor System
The Direct Tire Pressure Monitor System [1] in the RX 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.

[1] The Tire Pressure Monitor System alerts the driver when tire pressure is critically low. For optimal tire wear and performance, tire pressure should be checked regularly with a gauge; do not rely solely on the monitor system. Please see your Owner's Manual for details.

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 [1] . 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.

[1] Brake Assist is designed to help the driver take full advantage of the benefits of ABS. It is not a substitute for safe driving practices. Braking effectiveness also depends on proper brake-system maintenance and tire and road conditions.

Reinforced Body
The RX 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 improved load sustainability when buckled, helping to reduce the deformation of the cabin in the event of certain severe collisions.

Rain-Sensing Wipers
With the available rain-sensing wipers, if a sensor at the top of the windshield detects raindrops, the wiper blades are activated at an appropriate speed.

Theft-Deterrent System
With this theft-deterrent system, a rolling code immobilizes the engine unless the proper SmartAccess [1] [2] key is detected.

[1] The SmartAccess system may interfere with some pacemakers or cardiac defibrillators. If you have one of these medical devices, please talk to your doctor to see if you should deactivate this system.
[2]The engine immobilizer is a state-of-the-art anti-theft system. When you insert the key into the ignition switch or bring a SmartAccess fob into the vehicle, the key transmits an electronic code to the vehicle.  The engine will only start if the code in the transponder chip inside the key or SmartAccess fob matches the code in the vehicle’s immobilizer. Because the transponder chip is embedded in the key or SmartAccess fob, it can be costly to replace. If you lose a key or SmartAcess fob, your Lexus dealer can help.  Alternatively, you can find a qualified independent locksmith to perform high-security key services by consulting your local Yellow Pages or by contacting www.aloa.org.

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 [1] disengages. The feature does not engage if the brake pedal is pressed before the accelerator.

[1] Smart Stop Technology operates only in the event of certain simultaneous brake and gas pedal applications. When engaged, the system will reduce engine power to help the brakes bring the vehicle to a stop. Factors including speed, road conditions and driver input can all impact stopping distance. Smart Stop Technology is not a substitute for safe and  attentive driving and does not guarantee instant stopping. Please see  your Owner's Manual for further details.
