Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
●
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 indi-
cate that a malfunction has occurred in any of these systems.
●
Any of the following conditions may occur when the above systems are
operating. 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 is activated.
• The brake pedal may move down slightly after the ABS is activated.
■
Reactivation of the TRC/VSC systems after turning off the engine
Turning off the engine after turning off the TRC/VSC systems will automati-
cally reactivate them.
■
Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when
vehicle speed increases. However, when both TRC and VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.
■
If the VSC OFF indicator light blinks and the slip indicator light comes
on...
It may indicate a malfunction in the VSC and TRC. Consult your Toyota
dealer.
