Vehicles without a smart key system
To check that the indicator goes off, turn the engine switch to the “ON” posi-
tion, but do not start the engine.
Vehicles with a smart key system
To check that the indicator goes off, turn the engine switch to IGNITION ON

WARNING
■ To avoid an accident
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or ragged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to differential lock component parts.
● Do not drive over 5 mph (8 km/h) when the differential is locke d.
● Do not keep driving with the rear differential lock switch on.

Driving
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.
