■If the low speed four-wheel drive indicator continues to flash and a
buzzer sounds
The shift lever is not in N and/or the vehicle is moving. Stop the vehicle com-
pletely, shift the shift lever to N and make sure that the indicator stops flash-

■ Operating the four-wheel drive control switch
Never operate the four-wheel drive control switch if the wheels have lost
traction. Doing so may cause an accident resulting in death or serious injury.
Stop the wheels from slipping or spinning before operating the switch.
NOTICE
■ To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
● Do not lock or unlock the center differential when the vehicle is turning or
when its wheels are spinning freely off the ground.

When the active traction control system is operating
If all wheels spin, the slip indica-
tor flashes to indicate that the
active traction control system
has been engaged.

■When the rear differential is locked (vehicles with a rear differential
lock system)
The active traction control system is activated only when vehicle speed is
less than 4 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 indi-
cate that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. This may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “A-TRAC” indicator will go off and the “TRAC OFF (TRC
OFF)” indicator will come on. Stop the vehicle in a safe place. (There is no
problem with continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■The active traction control system m ay 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.

CAUTION
■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 rugged 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 rear differential lock component parts.
● Do not drive over 5 mph (8 km/h) when the rear differential is locked.
● Do not keep driving with the rear differential lock switch on.
