WARNING
■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.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and safety of the surrounding area can be ensured.
●Proper use of expert mode re quires a professional level of driving skill. When using
expert mode, always check the road condit ions and surrounding area and drive more carefully than usual.
■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.
■Handling of tires and the suspension
Using tires with any kind of problem or modif ying the suspension will affect the driving
assist systems, and may cause a system to malfunction.

◆Pre-crash warning
When a high possibility of a frontal
collision is detected, the pre-crash
safety system warning light flashes, a
buzzer sounds and a message is
shown on the multi-information dis-
play to urge the driver to take eva-
sive action.
◆Pre-crash brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is depressed.
The system may not warn the driver using a warning light, warning display and
buzzer when the system detects and judges braking operations.
◆Pre-crash braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning ligh t, warning display and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed.
◆Suspension control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the operation of Adaptive Variable Suspension System ( P. 350) opti-
mally controls the damping force of the shock absorber.
PCS (Pre-Crash Safety system)
: If equipped
When the radar sensor detects the possibil ity of a frontal collision, brakes are
automatically engaged to lessen im pact as well as vehicle damage.
The pre-crash safety system can be turn ed on and off as necessary by operat-
ing the switch. ( P. 357)
