The AdvanceTrac威 with RSC stability enhancement system can be turned

off manually by pressing the AdvanceTrac威 with RSC button (refer to

AdvanceTrac威 with Roll Stability Control (RSC) Stability

Enhancement System in this chapter) while operating in 2H, 4A or 4H

while driving in deep sand, very deep snow or more strenuous off-road

maneuvers. This will disable the engine management feature, allowing

the vehicle to maintain full power and enhanced momentum through the

obstacle.

How your vehicle differs from other vehicles

Truck and utility vehicles can differ from some other vehicles. Your

vehicle may be higher to allow it to travel over rough terrain without

getting hung up or damaging underbody components.

The differences that make your vehicle so versatile also make it handle

differently than an ordinary passenger car.

Maintain steering wheel control at all times, especially in rough terrain.

Since sudden changes in terrain can result in abrupt steering wheel

motion, make sure you grip the steering wheel from the outside. Do not

grip the spokes.

Drive cautiously to avoid vehicle damage from concealed objects such as

rocks and stumps.

You should either know the terrain or examine maps of the area before

driving. Map out your route before driving in the area. To maintain

steering and braking control of your vehicle, you must have all four

wheels on the ground and they must be rolling, not sliding or spinning.

Basic operating principles

• Do not use 4H (4x4) or 4L (4x4 LOW) on dry, hard surfaced roads.

This may damage the driveline and axles.

• Drive slower in strong crosswinds which can affect the normal steering

characteristics of your vehicle.

• Be extremely careful when driving on pavement made slippery by

loose sand, water, gravel, snow or ice.

If your vehicle goes off the edge of the pavement

• If your vehicle goes off the edge of the pavement, slow down, but

avoid severe brake application. Ease the vehicle back onto the

pavement only after reducing your speed. Do not turn the steering

wheel too sharply while returning to the road surface.

• It may be safer to stay on the apron or shoulder of the road and slow

down gradually before returning to the pavement. You may lose

control if you do not slow down or if you turn the steering wheel too

sharply or abruptly.
