◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
◆Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the road
surface is slippery due to snow, rain, etc.
◆Adaptive Variable Suspension System (if equipped)
Controls the damping force of the shock absorber of each wheel according to
the road and driving conditions, helping achieve a comfortable ride, excellent
driveability and a high level of stability.
If SPORT S+ mode is selected using the driving mode select switch, the
damping force will become more suitable for sporty driving. ( P. 418)
◆VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-start
assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road surfaces by
controlling the brakes and engine output
◆Emergency brake signal
When the brakes are applie d suddenly, the stop lights automatically flash to
alert the vehicle behind.

WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a
safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRC/VSC system is operating. Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist co ntrol is not intended to hold the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-trol to hold the vehicle on an incline, as doing so may lead to an accident.
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary. Trailer Sway Control is part of the VSC syst em and will not operate if VSC turned off or experiences a malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tire s are inflated to the recommended tire infla-
tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional for further information when replacing tires or wheels.
