2-4. Using other driving systems

CAUTION

■

Active TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slippery road

surfaces, even if the Active TRAC is operating.

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

■

If the hill-start assist control does not operate effectively

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 in ice.

■

When Active TRAC and VSC are off

Be especially careful and drive at a speed appropriate to the road conditions. As

these are systems to ensure vehicle stability and driving force, do not turn off Active

TRAC and VSC unless necessary.

■

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.

■

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 specified tire pres-

sure level.

The Multi Terrain ABS and VSC will not function correctly if different tires are fitted

on the vehicle.

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

■

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.
