■ Sounds and vibrations caused by the ABS, Multi Terrain ABS (if
equipped), brake assist, VSC, Trailer Sway Control, TRAC and hill-start
assist control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate 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 also 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.
■ Automatic reactivation of TRAC, Trailer Sway Control and VSC systems
After turning the TRAC, Trailer Sway Control and VSC systems off, the sys-
tems will be automatically re-enabled in the following situations:
● When the engine switch is turned off
● 2WD models: If the AUTO LSD system is turned on, the VSC, TRAC and
Trailer Sway Control systems will turn on when vehicle speed increases
● 4WD models: If only the TRAC system is turned off, the TRAC will turn on
when vehicle speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
