When driving
4RUNNER_U
■ Hill-start assist control operation conditions
● The shift lever is in D or S.
● The brake pedal is not depressed.
● The rear differential is unlocked (if equipped).
■ If the brake system overheats
The hill-start assist control will cease operation and a buzzer will sound to
alert the driver. At this time, the “TRAC OFF (TRC OFF)” indicator will come
on. Stop the vehicle in a safe place. (There is no problem with continuing
with normal driving.)
The system will be automatically restored after a short time.
■ Sounds and vibrations caused by the ABS, Multi Terrain ABS (if
equipped), brake assist, VSC, TRAC (TRC) and hill-start assist control
(if equipped) 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 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 or Multi Terrain
ABS is activated.
• The brake pedal may move down slightly after the ABS or Multi Terrain
ABS is activated.
■ Reactivation of the TRAC (TRC)/VSC systems after turning off the
engine
Turning off the engine after turning off the TRAC (TRC)/VSC systems will
automatically reactivate them.
■ Reactivation of the VSC system linked to vehicle speed (2WD models)
When the TRAC system is turned off and the AUTO LSD system is turned
on, the VSC system will turn on when vehicle speed increases. However,
when the TRAC and VSC systems are turned off, the systems will not turn
on even when vehicle speed increases.
