Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
higher revolutions per minute (RPM) than normal to make
sure the battery charges. High electrical loads may occur
when several of the following are on: headlamps, high
beams, fog lamps, rear window defogger, fan on high
speed, heated seats and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Monitor the battery voltage when in the BATTERY
SAVER ACTIVE mode.
If the voltmeter remains in the shaded area (below
11 volts) when driving then have the charging
system serviced immediately.
If the voltage increases above 12 volts then the
battery needs to be recharged. Try driving on
the highway with as few electrical accessories on
as possible.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information may
be displayed in English or metric units and appears as a
reection on the windshield. The HUD shows the
following:
Speedometer Reading
Turn Signal Indicators
High-beam Indicator Symbol
CHECK GAGES Message (for low oil pressure,
high coolant temperature, low oil level, high/low
battery, brake, ABS and air bag)
Low Fuel Warning Symbol
Radio Frequency and Playback Mode (with the
exception of the XM™ radio)

Tire Pressure Light
The check tire pressure system can alert you to a large
change in the pressure of one tire.
After the system has been
properly calibrated, the
TIRE PRESS light
will come on if a pressure
difference (low pressure)
is detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. SeeCheck Tire Pressure
System on page 5-68.
The TIRE PRESS light also comes on briey when you
turn your ignition key to START. If the light doesn’t
come on then, have it xed so it will be there to tell you
if the pressure in a tire is low.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-44.On vehicles with the optional Driver Information Center
(DIC), a CHECK TIRE PRESSURE message replaces
the TIRE PRESS light when the system detects a
pressure difference (low pressure) in one tire. SeeDIC
Warnings and Messages on page 3-61for more
information.
Malfunction Indicator Lamp
Service Engine Soon 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.
3-48

Check Gages Warning Light
If your vehicle has the
systems monitor, this light
will come on briey as a
bulb check when your
ignition is turned to ON.
If this light comes on and stays on while you are driving,
check your gages for fuel, coolant temperature, oil
pressure and voltage.
Door Ajar Light
If your vehicle has the
systems monitor, this light
will come on and a warning
chime will sound when the
driver’s door or one of the
passenger’s doors is not
completely closed.
On vehicles with a DIC, the door that is ajar will be shown
as an icon next to the vehicle outline and a message will
appear on the display. SeeDIC Warnings and Messages
on page 3-61for more information.

Tire Pressure Status:Press the SELECT button until
TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle’s tire
pressures are normal. If a potential problem is detected,
the display will show CHECK TIRE PRESSURE and
the tire pressure status will show TIRE PRESSURE
LOW. If you see the CHECK TIRE PRESSURE
message, you should stop as soon as you can and
check all your tires for damage. If a tire is at, seeIf a
Tire Goes Flat on page 5-79. Also check the tire
pressure in all four tires as soon as you can. See
Ination - Tire Pressure on page 5-67andCheck Tire
Pressure System on page 5-68.DIC Warnings and Messages
Other messages or warnings may appear in the DIC
display. For Canadian drivers, in addition to the
DIC message your DIC will display EXP with a number
after it which reects the following messages:
EXP

Once you are moving on the freeway, make certain you
allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

Cold Ination Pressure:The amount of air pressure in
a tire, measured in pounds per square inch (psi) before a
tire has built up heat from driving. SeeInation - Tire
Pressure on page 5-67.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment including
the maximum capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings:A code molded into the sidewall of a
tire signifying that the tire is in compliance with the U.S.
Department of Transportation motor vehicle safety
standards. The DOT code includes the Tire Identication
Number (TIN), an alphanumeric designator which can
also identify the tire manufacturer, production plant,
brand and date of production.
GVWR:Gross Vehicle Weight Rating, seeLoading
Your Vehicle on page 4-33.
GAWR FRT:Gross Axle Weight Rating for the front
axle, seeLoading Your Vehicle on page 4-33.
GAWR RR:Gross Axle Weight Rating for the rear axle,
seeLoading Your Vehicle on page 4-33.
Intended Outboard Sidewall:The side of an
asymmetrical tire that must always face outward when
mounted on a vehicle.Kilopascal (kPa):The metric unit for air pressure.
There are 6.9 kPa’s to one psi.
Light Truck (LT-Metric) Tire:A tire used on light duty
trucks and some multipurpose passenger vehicles.
Load Index:An assigned number ranging from 1 to 279
that corresponds to the load carrying capacity of a tire.
Maximum Ination Pressure:The maximum air
pressure to which a cold tire may be inated. The
maximum air pressure is molded onto the sidewall.
Maximum Load Rating:The load rating for a tire at the
maximum permissible ination pressure for that tire.
Maximum Loaded Vehicle Weight:The sum of curb
weight; accessory weight; vehicle capacity weight;
and production options weight.

Ination - Tire Pressure
The Tire and Loading Information label, shows the correct
ination pressures for your tires when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours or driven no more than 1 mile (1.6 km). See
Loading Your Vehicle on page 4-33, for the location of
your vehicle’s tire and loading information label.
If you’ll be driving at high speeds (e.g., speeds of
100 mph (160 km/h) or higher), where it is legal, set the
cold ination pressure to the maximum ination pressure
shown on the tire sidewall, or to 35 psi (244 kPa),
whichever is lower. See the example below. When you
end this high–speed driving, return to the cold ination
pressure shown on the Tire–Loading Information label.
Example:
You’ll nd maximum load and ination pressure molded
on the tire’s sidewall, in small letters near the rim
ange. It will read something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the ination pressure
for high-speed driving at 35 psi (244 kPa).Notice:Don’t let anyone tell you that underination
or overination is all right. It’s not. If your tires
don’t have enough air (underination), you can get
the following:
Too much exing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overination), you
can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards

Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
*If your vehicle has the GM Oil Life System, a computer
system lets you know when to change the oil and
lter. This is based on engine revolutions and engine
temperature and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
An ENGINE OIL CHANGE SOON message will come on.
Change your oil as soon as possible within the next two
times you stop for fuel. It is possible that, if you are driving
under the best conditions, the oil life system may not
indicate that an oil change is necessary for over a year.
However, your engine oil and lter must be changed at
least once a year and at this time the system must be
reset. It is also important to check your oil regularly and
keep it at the proper level.If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil on
page 5-16 for information on resetting the system.
Whenever the tires are rotated, the Check Tire Pressure
System must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-24.
