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.
Do not drive the vehicle in conditions where stability and power may be lost.
■
When the Enhanced 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 TRAC and Enhanced VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to help ensure vehicle stability and driving force,
do not turn off TRAC and Enhanced VSC 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 appro-
priate tire pressure level.
The ABS and Enhanced VSC systems will not function correctly if different
tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
