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 locked.
●Do not keep driving with the rear differential lock switch on.

■When the rear differential is locked (vehicles with the rear differential
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 system
●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 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 the 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 power may be lost.

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 stating 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 improved 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
