hills, or in deep snow or mud. If the selector lever is

until the vehicle is going slowly enough.
The parking brakes uses the brakes on the rear wheels.
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.

how many miles you have Warning lights and gages can signal t\

driven since you last set it wrong before it becomes serious enough to cause an

TO reset, push expensive repair or replacement. Paying attention to
the button. your warning lights and gages could also save 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.
This section describes the warning lights and gages that
are on your vehicle. The pictures will help
you locate
them. 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.

Fuel Gage
I
Your fuel gage is a bar graph. When you fill the tank,
the bar segments will light up. The fuel gage shows
about how much fuel is in your
tank. It works only when
the ignition is on. When the fuel gage shows only two
bar segments the
“LOW’ light will come on. If the fuel
~ supply is in the one bar segment, the yellow warning bar
’ will flash to remind you to get more fuel soon.
At the gas station, the gas pump shuts off before the
gage reads
“F’.
It takes more (or less) gas to fill up than the gage
said. For example, the gage said
1/2 full, but it took
more
- or less - than half of the tank’s, capacity to fill
it.
Engine Oil Pressure Gage and Light
When “LOW, comes on
there could be a problem
with your engine oil
pressure.
~ Here are concerns some owners have had about the fuel You
can also read your oil pressure directly from the
~ gage. All these situations are normal and indicate gage on you\
r instrument panel.
I
nothing wrong with the fuel gage.

problem. 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

warn you if there’s a problem. This light will
also come
on when you set your parking
brake, and 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. If the
light comes on while 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.)
I A CAUTION:
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake warning light on can lead
to an accident.

road and stopped carefully, have the vehicle
towed for service.
