Section 4 Driving Your Vehicle

Remember: ABS does not change the time you
need to get your foot up to the brake pedal
or always decrease stopping distance. If you get
too close to the vehicle in front of you, you will not
have time to apply your brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may feel the brakes vibrate, or you may notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Locking Differential
If your vehicle has this feature, your locking
differential can give you additional traction on snow,
mud, ice, sand or gravel. It works like a standard
axle most of the time, but when one of the wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
StabiliTrak®System
Your vehicle may be equipped with the
StabiliTrak®system which combines antilock
brake, traction and stability control systems and
helps the driver maintain directional control of the
vehicle in most driving conditions.
When you rst start your vehicle and begin to
drive away, the system performs several diagnostic
checks to ensure there are no problems. You
may hear or feel the system working. This
is normal and does not mean there is a problem
with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately
two miles of driving before the system initializes.

How to Check Lubricant
To get an accurate reading, the vehicle should be
on a level surface.
A:Fill Plug
B:Drain PlugIf the level is below the bottom of the ller plug
hole, located on the front axle, you may need
to add some lubricant:
When the differential is cold, add enough
lubricant to raise the level from 0 (0 mm)
to 1/8 inch (3.2 mm) below the ller plug hole.
When the differential is at operating
temperature (warm), add enough lubricant
to raise the level to the bottom of the ller
plug hole.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 561.
