Driving
■When the rear differential is l ocked (vehicles with the rear di fferential
lock system)
The active traction control system is activated only when the vehicle speed is
less than 3 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control sys tem
● A sound may be heard from the engine compartment when the engin e is
started or just after the vehicle begins to move. This sound do es not indicate
that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. It may occur
when the system is operating.
■ If the brake system overheats
The system will cease operation, a buzzer will sound to alert t he driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
The system will be automatically restored after a short time.
WARNING
■ The active traction control system may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and powe r may be lost.

3104-5. Using the driving support systems
Operate the Multi-terrain Select
mode selector dial during Multi-
terrain Select control to select a
mode.
■The Multi-terrain Select can be operated when
●The four-wheel drive control switch is in “4L” position.
● The Crawl Control is off.
■ When using the Multi-terrain Select
The VSC system cannot be switched on or off.
A message will be shown on the multi-information display statin g that this
function cannot be switched using the VSC off switch.
■ 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.
If the current tires slip is too large, driveability can be imp roved by selecting a
mode with a smaller slip amount. Conversely, selecting a mode with a larger
slip can improve driveability, if the current tire slip is too small.
■ When the vehicle is stuck

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
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 suddenl y,
or if the brakes are applied while driving on a slippery road s urface,
or in off-road conditions (such as rough roads, sand and mud)
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control (if equipped)
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 ope rate if
VSC system 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 vehicl e or accelerating on slippery roads
To help enhance driving safety and performance, the following
systems operate autom atically 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.
