operate:
• The transfer mode is not in L4 (part-time 4WD models) or L4L (full-time
4WD models).
• The rear differential is locked.
• The brake system overheats. The system will cease operation and a buzzer will sound to alert the
driver. At this time, the “TRAC OFF” indicator will come on. Stop the
vehicle in a safe place. Refrain from using the system until the indicator
stops flashing and stays on. (There is no problem with continuing nor-
mal driving.)
● In the following situations, the indicator flashes to alert the driver, but the
system will still operate:
• The shift lever is in N. (Engine braking will not occur.)
• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operation. The indicator will flash dur-
ing operation, and then go off when the system is fully off.

■Crawl Control is temp orarily canceled when
Vehicle speed exceeds 15 mph (25 km/h). The Crawl Control indicator
flashes until the vehicle speed is reduced.
■ Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Control indicator will flash until the sys-
tem is turned off completely.
● When the shift lever is shifted to P or N
● When the front-wheel drive control lever or switch is shifted to H4
● When the driver’s door is opened
● When the system is malfunctioning
● When the brake system overheats
Stop the vehicle in a safe place. (There is no problem with continuing
normal driving.)
● When the automatic transmission system overheats
Stop the vehicle in a safe place until the automatic transmission fluid tem-
perature warning light goes off.
■ Sounds and vibrations caused by the Crawl 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 Crawl Control system.
● Either of the following conditions may occur when the Crawl Control sys-
tem is operating. None of these indicates that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■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 surface
■Multi Terrain ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface, or in off-
road conditions (such as rough roads, sand and mud)
The Multi Terrain ABS operates in syn chronization with the Multi-terrain
Select.
■ Brake assist
Generates an increased level 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
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on an
incline or slippery slope
■LSD (Limited Slip Differential) (if equipped)
Transfers drive power to the rear tires when front tires spin, and vice
versa, in order to improve traction

driving.)
The system will be automatically restored after a short time.
■ Sounds and vibrations caused by the ABS, Multi Terrain ABS (if
equipped), brake assist, VSC, TRAC and hill-start assist control (if
equipped) systems
● 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 any of these systems.
● Any of the following conditions 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 after the ABS or Multi Terrain
ABS is activated.
• The brake pedal may move down slightly after the ABS or Multi Terrain ABS is activated.
■ Reactivation of the TRAC/VSC systems after turning off the engine
