◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Multi Terrain ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface,
or in off-road conditions (such as rough roads, sand and mud)
The Multi Terrain ABS operates in synchronization with the Multi-
terrain Select.
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing engine torque when
trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate
if VSC is turned off or experiences a malfunction.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

◆Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on
an incline or slippery slope
◆LSD (Limited Slip Differential) (if equipped)
Transfers drive power to the rear tires when front tires spin, and
vice versa, in order to improve traction
◆KDSS (Kinetic Dynamic Suspension System) (if equipped)
Enhances ride comfort and handling response by using a hydraulic
control system to cont rol the suspension stabilizer bars in response
to road surface and driving condi tions during cornering or off-road
driving
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the TRAC/VSC/
Trailer Sway Control systems are
operating.
If the vehicle is in danger of slip-
ping or rolling backward when
starting on an incline, or if any of
the drive wheels spins, the slip
indicator flashes to indicate that
the TRAC/VSC/Trailer Sway Con-
trol/hill-start assist control sys-
tems are operating.
The stop lights and high mounted
stoplight turn on and a buzzer
(intermittent) sounds when the hill-
start assist control system is oper-
ating.

■When the “TRAC OFF” indicator li ght comes on even if the VSC off
switch has not been pressed
TRAC, hill-start assist control, downhill assist control and Crawl Control can-
not be operated. Contact your Toyota dealer.
■ Hill-start assist contro l 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” indicator will come on. Stop the
vehicle in a safe place. (There is no problem with continuing with normal driv-
ing.)
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, Trailer Sway Control, TRAC 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 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 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/VSC/Trailer Sway Control systems after turn-
ing off the engine
Turning off the engine after turning off the TRAC/VSC/Trailer Sway Control
systems will automatically reactivate them.

Reactivation of the VSC and Trailer Sway Control system linked to vehi-
cle speed (2WD models)
When the TRAC system is turned off and the AUTO LSD system is turned on,
the VSC and Trailer Sway Control system will turn on when vehicle speed
increases. However, when the TRAC, VSC and Trailer Sway Control systems
are turned off, the systems will not turn on even when vehicle speed
increases.
■ Reactivation of the TRAC/VSC/Trail er Sway Control systems (4WD mod-
els)
If the TRAC/VSC/Trailer Sway Contro l systems are turned off, the systems
will not turn on even when vehicle speed increases.
CAUTION
■ The ABS and Multi Terrain ABS do not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS or Multi Terrain ABS is operating may
exceed that of normal conditions
The ABS and Multi Terrain ABS are not designed to shorten the vehicle’s
stopping distance. Always maintain a safe distance from the vehicle in front
of you, especially in the following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces
■ TRAC may not operat e 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.
■ Hill-start assist control do es not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
