The TRAC OFF will be shown on the multi-information display.

Press the button again to turn the system back on.

Turning off both TRAC or Active TRAC and VSC systems

To turn the TRAC or Active TRAC and VSC systems off, press and hold the button for 3 seconds and more while the vehicle is stopped.

The VSC OFF indicator light will come on and the TRAC OFF will be shown on the multi- information display.

Hill-start assist control operation conditions

• The shift lever is in D or S.

• The brake pedal is not depressed.

Sounds and vibrations caused by the ABS/Multi Terrain ABS, brake assist, VSC, TRAC/Active TRAC and hill-start assist control systems

• A sound may be heard from the engine compartment when the engine is started or just after the vehicle begins to move. This sound does not indicate that a malfunction has occurred in any of these systems.

• Any of the following conditions may occur when the above systems are operat- ing. None of these indicates that a malfunction has occurred.

• Vibrations may be felt through the vehicle body and steering.

• A motor sound may be heard after the vehicle comes to a stop.

• The brake pedal may pulsate slightly after the ABS/Multi Terrain ABS is acti- vated.

• The brake pedal may move down slightly after the ABS/Multi Terrain ABS is activated.

Reactivation of the TRAC or Active TRAC/VSC systems after turning off the engine

Turning off the engine after turning off the TRAC or Active TRAC/VSC systems will automatically reactivate them.

Reactivation of the TRAC or Active TRAC system linked to vehicle speed

When only the TRAC or Active TRAC system is turned off, the TRAC or Active TRAC system will turn on when vehicle speed increases. However, when both TRAC or Active TRAC and VSC systems are turned off, the systems will not turn on even when vehicle speed increases.

When the brake system operates continuously

The brake actuator may overheat. In this case, the TRAC or Active TRAC and hill- start assist control systems will stop operating, a buzzer will sound and the TRAC OFF will be shown on the multi-information display. Refrain from using the system until the message goes off. (There is no problem with continuing normal driving.)

If the slip indicator comes on...

It may indicate a malfunction in the VSC, TRAC/Active TRAC or hill-start assist control system. Consult your Lexus dealer.

CAUTION

The ABS/Multi Terrain ABS does not operate effectively when

• Tires with inadequate gripping ability are used (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/Multi Terrain ABS is operating may exceed that of normal conditions

The ABS/Multi Terrain ABS is not designed to shorten the vehicle’s stopping dis- tance. Always maintain a safe distance from the vehicle in front of you in the follow- ing 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 roads with uneven surfaces

CAUTION

TRAC/Active TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRAC/Active TRAC is operating.

Do not drive the vehicle in conditions where stability and power may be lost.

Hill- start assist control does not operate effectively when

Do not overly rely on the hill-start assist control. The hill-start assist control may not operate effectively on steep inclines and roads covered with ice.

When the VSC is activated

The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.

Reckless driving may cause an accident. Exercise particular care when the indica- tor light flashes and a buzzer sounds.

When the TRAC or Active TRAC/VSC systems are turned off

Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to ensure vehicle stability and driving force, do not turn the TRAC or Active TRAC/VSC systems off unless necessary.

Replacing tires

Make sure that all tires are of the same size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pressure level.

The ABS/Multi Terrain ABS and VSC systems will not function correctly if different tires are installed on the vehicle.

Contact your Lexus dealer for further information when replacing tires or wheels.

CAUTION

Handling of tires and suspension

Using tires with any kind of problem or modifying the suspension will affect the driv- ing assist systems, and may cause the system to malfunction.
