2-4. Using other driving systems
CAUTION
■
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Be especially careful and drive the vehicle in conditions where stability and
power may be lost.
■
When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■
When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. Do not turn the TRAC/VSC systems off unless necessary, as these are
the systems to ensure vehicle stability and driving force by automatically
controlling braking and engine outputs.
■
Replacing tires
Observe the following precautions.
Failure to do so may cause the ABS, VSC and TRAC systems not to function
correctly.
●
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity.
●
Do not use tires of noticeably different wear level.
●
Make sure that the tires are inflated to the recommended tire inflation
pressure level. (

Contact your Toyota dealer for further information when replacing tires or

Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
