Descend a hill in the same gear you

would use to climb up the hill to

avoid excessive brake application

and brake overheating. Do not

descend in neutral, disengage

overdrive or manually shift to a

lower gear. When descending a

steep hill, avoid sudden hard

braking as you could lose control.

When you brake hard, the front

wheels can’t turn and if they aren’t

turning, you won’t be able to steer.

The front wheels have to be turning in order to steer the vehicle. Rapid

pumping of the brake pedal will help you slow the vehicle and still

maintain steering control.

If your vehicle has anti-lock brakes, apply the brakes steadily. Do not

“pump” the brakes.

Driving on snow and ice

4WD vehicles have advantages over 2WD vehicles in snow and ice but

can skid like any other vehicle.

Should you start to slide while driving on snowy or icy roads, turn the

steering wheel in the direction of the slide until you regain control.

Avoid sudden applications of power and quick changes of direction on

snow and ice. Apply the accelerator slowly and steadily when starting

from a full stop.

Avoid sudden braking as well. Although a 4WD vehicle may accelerate

better than a two-wheel drive vehicle in snow and ice, it won’t stop any

faster, because as in other vehicles, braking occurs at all four wheels. Do

not become overconfident as to road conditions.

Make sure you allow sufficient distance between you and other vehicles

for stopping as well as drive slower than usual and consider using one of

the lower gears. In emergency stopping situations, avoid locking of the

wheels. Use a “squeeze” technique, push on the brake pedal with a

steadily increasing force which allows the wheels to brake yet continue

to roll so that you may steer in the direction you want to travel. If you

lock the wheels, release the brake pedal and repeat the squeeze

technique. If your vehicle is equipped with a Four Wheel Anti-Lock

Brake System (ABS), apply the brake steadily. Do not “pump” the

brakes. Refer to the Brakes section of this chapter for additional

information on the operation of the anti-lock brake system.
