may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.

water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or moisture condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from the
windshield more quickly.
Select one of these available modes from the
right knob.

Use the lever located in the center of each outlet to
change the direction of the airflow. Use the thumbwheel
located above the side outlets to turn them on and off.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle has a passenger compartment air filter.
It is located on the passenger side at the base of
the windshield and can be accessed through a
removable panel under the hood of the vehicle.
The filter traps most of the pollen from air entering the
module. Like your engine’s air cleaner/filter, it may
need to be changed periodically.

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.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven in kilometers.
Trip Odometer
The trip odometer can record the number of kilometers
traveled for up to two trips.
The trip odometer
buttons are located to
the right of the steering
wheel above the ignition
switch.
You can cycle between the odometer and trip
odometers A and B by pressing the MODE button.
By pressing this button, you can tell how many
kilometers have been recorded on either Trip A or
Trip B since you last set the odometer back to zero.Press the RESET button until zeros appear to reset each
trip odometer. The RESET button resets only the trip
odometer that is being displayed. Each trip odometer
must be reset individually.
Tachometer
The tachometer
displays your engine
speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should turn on for a few
seconds when you turn the ignition to ON. If the light
does not come on then, have it fixed so it will be ready
to warn you if there is a problem.
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
and the engine is not
running, as a check
to show you it is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose generator drive
belt, or another electrical problem. Have it checked right
away. Driving while this light is on could drain your
battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

Anti-Lock Brake System Warning
Light
If your vehicle has an
anti-lock brake system,
this light will come on when
the ignition is turned to
ON and may stay on
for several seconds.
That is normal.
If the light stays on, turn the ignition to LOCK. Or, if the
light comes on, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you are driving, your vehicle needs service. If the
regular brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also on,
you do not have anti-lock brakes and there is a problem
with your regular brakes. SeeBrake System Warning
Light on page 3-35.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key to ON. This is
normal. If the light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
Speed Sensitive Power Steering
(SSPS) Warning Light
This warning light will
come on briefly when
you turn the ignition
to ON as a check to
show you it is working.
Then it should go out after a few seconds.
If the warning light does not come on, have it fixed so
it will be able to warn you if there is a problem.
If the warning light stays on, or comes on while you are
driving, the SSPS system may not be working. If this
happens, see your dealer for service.

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant temperature
gage. With the ignition
turned to ON, this
gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot. It means that your engine coolant has
overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-22.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (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 Check Engine 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.
