Sounds and vibrations caused by the ABS/Multi Terrain ABS, brake assist, VSC, Trailer
Sway Control, TRAC/Active 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 sys-
tems.
●
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/Multi Terrain ABS is activated.
• The brake pedal may move down slightly after the ABS/Multi Terrain ABS is acti-

Automatic reactivation of TRAC/Active TRAC, Trailer Sway Control and VSC systems
After turning the TRAC/Active TRAC, Trailer Sway Control and VSC systems off, the
systems will be automatically re-enabled in the following situations:
●
When the engine switch is turned off
●
If only the TRAC/Active TRAC system is turned off, the TRAC/Active TRAC will turn
on when vehicle speed increases
If both the TRAC/Active TRAC and VSC systems are turned off, automatic re-enabling
will not occur when vehicle speed increases.
■
When the brake system operates continuously
The brake actuator may overheat. In this case, the TRAC/Active TRAC and hill-start
assist control systems will stop operating, a buzzer will sound and the “TRAC OFF” indi-
cator will come on. Refrain from using the system until the message goes off. (There is no
problem with continuing normal driving.)
■
If the slip indicator comes on...
It may indicate a malfunction in the TRAC/Active TRAC, VSC/Trailer Sway Control or
hill-start assist control system. Consult your Lexus dealer.
■
KDSS
Some difference of vehicle height between left and right side can appear. This does not
indicate a malfunction in the KDSS system. For more information, contact your Lexus
dealer.
