●If Crawl Control is used continuously for a long time, the buzzer will sound, a malfunc-
tion notification will be displayed on the multi-information display, the Crawl Control
indicator will go off, and Crawl Control will be temporarily inoperable as a result of the
brake system overheating. In this event, stop the vehicle immediately in a safe place,
and allow the brake system to cool down sufficiently until the TRAC OFF indicator
goes off. (In the meantime, normal driving is possible.)
●If Crawl Control is used continuously for a long time, the buzzer will sound, the system

■When it is difficult to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed by LOOSE
ROCK, MOGUL, ROCK & DIRT and ROCK mode.
Drivability can be improved by selecting a mo de which provides a smaller amount of tire
slippage than the current mode when the amount of tire slippage is large, or conversely
selecting a mode which provides a larger amou nt of tire slippage than the current mode
when the amount of ti re slippage is small.
■When the vehicle is stuck
Switching the transfer and differential
For the operation of the following functions, refer to the following pages.
●Four-wheel drive system ( P. 3 0 5 )
●Center differential lock ( P. 3 0 6 )

The brake system may overheat. In this case, a buzzer will sound, the TRAC OFF indica-
tor will flash, and Multi-terrain Select will be temporarily inoperable. In this event, stop
the vehicle immediately in a safe place, and allow the brake system to cool down suffi-
ciently. (There is no problem wi th continuing normal driving.)
After a short time, the TRAC OFF indicator will go off, and you will be able to use Multi-
terrain Select.

Driving assist systems
◆Multi Terrain 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 su
rface, or in off-road conditions (such as
rough roads, sand and mud)
◆Brake assist
Generates an increased leve l 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
◆Active TRAC (Traction Control)
Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippery roads, or in off-road conditions
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on an incline or
slippery slope
◆AVS (Adaptive Variable Suspension system)
By independently controlling the damping force of the shock absorbers for each of
the 4 wheels according to the road and dr iving conditions, this system helps riding
comfort with superior stee ring stability, and helps good vehicle posture. When
SPORT S+ mode is selected by the drivin g mode select switches, the damping force
is suitable for sporty driving. ( P. 2 8 6 )
◆VGRS (Variable Gear Ratio Steering)
Helps to adjust the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine to rque when trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC turned off
or experiences a malfunction.
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.

The slip indicator light flashes to indi-
cate that the VSC/Trailer Sway Con-
trol/Active TRAC/hill-start assist
control systems have been engaged.
The stop lights and high mounted stop-
light turn on when
the hill-start assist
control system or Trailer Sway Control is
operating.
If the vehicle gets stuck in fresh snow or mud, Active TRAC system reduce
power from the engine to the wheels. You may need to turn the system off to
enable you to rock the vehicle in order to free it.
Quickly push and release the button to
turn off Active TRAC.
The TRAC OFF indicator will come on.
Push the button again to turn the system
back on.
■Turning off Active TRAC, VSC and Trailer Sway Control
Push and hold the button for more than 3 seconds while the vehicle is stopped to turn off
Active TRAC, VSC and Trailer Sway Control
The VSC OFF indicator light and TRAC OFF indicator will come on.

Push the button again to turn the system back on.
*: On vehicles with pre-collision system, pre-collision brake assist and pre-collision brak-ing will also be disabled. The PCS warning light will come on and the message will be
shown on the multi-information display. ( P. 2 5 0 )
■Automatic reactivation of Active TRAC, VSC and Trailer Sway Control
Turning the engine switch off after turning off the Active TRAC and VSC systems will
automatically re-enable them.

■Automatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC system will turn on when
vehicle speed increases.
■Automatic Active TRAC, VSC and Trailer Sway Control reactivation
If the Active TRAC, VSC and Trailer Sway Control are turned off, the systems will not
turn on even when vehicle speed increases.
■If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and the TRAC OFF
indicator will flash, and Active TRAC and hill- start assist control will be temporarily inop-
erable. In this event, stop the vehicle immediately in a safe place, and allow the brake sys-
tem to cool down sufficiently until the TR AC OFF indicator goes off. (There is no
problem with continuing normal driving.)
■Sounds and vibrations caused by the Mult i Terrain ABS, brake assist, Active TRAC,
VSC, Trailer Sway Control, hill-start assist control and VGRS
●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 condit ions 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 af ter the Multi Terrain ABS is activated.
• The brake pedal may move down slightly after the Multi Terrain ABS is activated.
■Hill-start assist cont rol is operational when
●The shift lever is in D or S.
●The brake pedal is not depressed.
■VGRS is disabled in the following situations
●During stopping or the steering wheel has been moved for a long time while driving at
lower speeds.
●After the engine is restarted at less than -22°F (-30°C).
●If you disconnect the battery with the steeri ng wheel turned, the center position of the
steering wheel could be slightly and tempor ary changed. To initialize the VGRS, drive
for a short while.
