Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in airow, which may occur more
often in dusty areas, indicate that the lter may need to
be replaced early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
The passenger compartment air lter and access
panel are located on the passenger’s side of
the engine compartment near the battery.

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 briey when you start the
engine just to let you know they are 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 is 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 are a big help.
Your vehicle may also have a Driver Information Center
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-64.

Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h).
There is only one scale for mph and km/h. Use
the Driver Information Center (DIC) controls to switch
between mph and km/h. SeeDIC Controls and Displays
on page 3-64for more information. The cluster will
calculate the proper speed and move the needle to the
correct position. Either the MPH or the km/h telltale
will illuminate, depending on which measurement you
choose.
The odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-64for more information.
Trip Odometer
The trip odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-64for more information.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6700 rpm.
If you continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure to
operate your vehicle below the fuel shut off rpm or
reduce your rpm quickly when the fuel shuts off.
Safety Belt Reminder Light
When the ignition button is pressed to START, a chime
will be provided for several seconds to remind people
to buckle their safety belts. The driver safety belt
light will also be provided and stay on for several
seconds, then it will ash for several more. You should
buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled and
the vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.

Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the
engine is running,
it shows the voltage
output of the charging
system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel
cluster and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter
reading at 10 volts or below could drain your battery
and disable your vehicle.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-29
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.
