Locking Rear Axle
If you have this feature, your rear axle 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 rear wheels has no traction and the other does, the
locking feature will allow the wheel with traction to move the vehicle.
To set the parking brake:
Hold the regular brake
pedal down with your
right foot. Push down the parking brake
pedal with your left
foot.
If the ignition is on, the brake system warning light will come on.
To release the parking brake:
Hold the regular brake
pedal down. Pull the lever, located just
above the parking
brake pedal, marked
RELEASE to release
the parking brake.
-
If the ignition is on when the parking brake is released, the brake system
warning light will
go off.

Warning Lights and Indicators
This section describes the warning lights and gages that may b\
e on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something
is wrong before it
becomes serious enough to cause an expensive repair or replacem\
ent.
Paying attention to your warning lights and gages could also s\
ave you or
others from injury.
Warning lights go on when there may be
or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition\
key just to
let you know they’re working.
If you are familiar with this section, you
should not be alarmed when this happens.

Gages can indicate when there may be or is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let
you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving,
or when one of the gages shows there may be a problem, check the
section that tells you what to do about
it. Please follow the manual’s advice.
Waiting
to do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re
a big help.
Brake System Warning Light
The red brake system
warning light is
located at the bottom
right corner
of the
instrument cluster
Your vehicle’s hydraulic brake system
is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good braking,
though, you need both parts working well.
Your vehicle also has rear-wheel anti-lock brakes.
If the warning light
comes on, there could be
a brake problem with either your regular or
rear-wheel anti-lock brakes, or both. Have your brake system inspected
right away.
This light should come on
as you start the vehicle. If it doesn’t come on
then, have it fixed so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully.
You may notice that the pedal is harder to push. Or, the pedal may
go closer
to the floor. It may take longer to stop. If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)

A CAUTION:
The brake system warning light will also come on when you set your
parking brake, and
it will stay on if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it means you have a
brake problem.
Water in Fuel Light
The red Water in Fuel
light,
if you have one,
is located near the
middle right edge of
the instrument cluster,
just below the turn
signal and lane change
indicator.
This light will come on to warn you
if there is water in the diesel fuel
system. For more information on how this light works, see “Diesel Fuel
Requirements and Fuel System”
in the Index.

or some other charging system problem.

your accessories, such as the radio and air conditioner.
