Downloaded from www.Manualslib.com manuals search engine NOTICE:
Driving with the parking brake on can cause your
rear brakes to overheat.
You may have to replace
them, and you could also damage other parts of
your vehicle. Always check to be
sure your parking
brake is fully released before you drive.
If
you are towing a trailer and are parking on any hill,
see “Towing a Trailer” in the Index. That section shows
what to do first to keep the trailer from moving.
It can be dangerous to get out of your vehicle if
the shift lever
is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
If
you have left the engine running, the vehicle can
move suddenly.
You or others could be injured.
To be sure your vehicle won’t move, even when
you’re on fairly level ground, use the steps that
follow.

The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever
will return automatically.
H

An arrow on the instrument
panel will flash
in the
direction of the turn or
lane change.
To signal
a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it. As
you signal a
turn or a lane change, if the arrows flash
at twice the normal rate,
a signal bulb may be burned
out and other drivers may not see your turn signal.
If
a bulb is burned out, replace it to help avoid an
accident. If
the arrows don’t go on at all when you
signal a turn, check for burned-out bulbs and a blown
fuse (see “Fuses and Circuit Breakers”
in the Index).
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this light on the
instrument panel also will
be on.

n 8 1,
i .:.
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (kdh). Your
odometer shows how
far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used
in Canada).
You may wonder what happens if your vehicle needs a
new odometer installed. Laws vary as
to the procedure
that must be followed,
so check with your state or
provincial vehicle registration office.
But generally, if
the new odometer can be set to the mileage total of the
old odometer, then it must be. But if it can’t, then it’s set
at zero, and a label must be put on the driver’s door to
show the old mileage reading when the new odometer
was installed.
Trip Odometer
The trip odometer can tell
you how far your vehicle
has been driven since
you
last set the trip odometer
to zero.
To reset the trip odometer,
fully press the reset button
located near
the trip odometer readout.
The trip odometer can show either total miles or trip
miles by using the push control in
the cluster.

This optional system automatically controls vehicle top
speed. The system controller receives a signal from the
vehicle speed sensor and reduces power when the
vehicle speed reaches
the maximum 65 mph (105 kdh)
governed speed.
Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be 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 replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come 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 start the
engine 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 this 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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about
20 seconds, then it
will flash for about
55 seconds.
If the driver’s belt is already buckled, neither the tone
nor the light will come on.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensor, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR
BAG
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should
go out. This means
the system is ready.
If
the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away. The
air bag readiness light should flash for
a few
seconds
when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem.
Charging System Light
This light should come on
briefly
when you turn on the
ignition, before starting the
engine,
as a check to show
you it is working.
After the engine starts, the light should
go out. If it stays
on or comes on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the alternator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it
helps to turn off all your accessories, such as the radio
and air conditioner.

with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions
are at acceptable levels for the life
of the vehicle, helping
to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on to indicate that there
is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be
as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when
the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light
will also come on during a malfunction in one
of two ways:
0
0
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle.
GM or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
GM
or qualified service center diagnosis and service may
be required.

Downloaded from www.Manualslib.com manuals search engine Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may
go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank
of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
