Dome Lamp Override
E(Dome Lamp Override):You can use the
dome override button, located below the exterior
lamps control, to set the dome and footwell
lamps to come on automatically when a door is
opened, or to remain off. To turn the lamps
off, press the button into the in position. With the
button in this position, the dome lamps will
remain off when the doors are open. To return
the lamps to automatic operation, press the
button again and return it to the out position.
With the button in this position, the dome lamps
will come on when you open a door.
Exit Lighting
With exit lighting, the interior lamps will come
on when you remove the key from the ignition.
The lamps will not come on if the dome override
button is pressed in.
Reading Lamps
Your vehicle has reading lamps. Press the button
located next to the lamp to turn them on or off.
These lamps will not come on with the dome lamps.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.

0(Defrost):Turn the right knob on the control
panel to this mode to direct most of the air to the
windshield, and the side window outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature
is near or below freezing. Recirculation is not
available in this mode.
Do not drive the vehicle until all the windows
are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window when
the key is in the ignition and turned to ON.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger
on or off. First press of this button will activate
the rear window defogger for 15 minutes and
each subsequent activation lasts seven and
one-half minutes.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and
on the side of your instrument panel to direct
the airow.
Your vehicle has air outlets that allow you to
adjust the direction and amount of airow inside
the vehicle. Move the louvers up or down to
change the direction of the airow. Use the
thumbwheel under the outlets to change the
direction of the airow from left to right.
Operation Tips

Enable recirculation mode for maximum
air conditioning performance.
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 path under the front seats clear
of objects to help circulate the air inside
of your vehicle more effectively.

If you put things inside your vehicle — like
suitcases, tools, packages, or anything
else — they will go as fast as the vehicle goes.
If you have to stop or turn quickly, or if there
is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops
of the seats.
Do not leave an unsecured child
restraint in your vehicle.
CAUTION: (Continued)
CAUTION: (Continued)

When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.

(E) Rim Diameter:Diameter of the wheel in
inches.
(F) Service Description:The service description
indicates the load range and speed rating of a
tire. The load index can range from 1 to 279.
Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission/
transaxle, power steering, power brakes, power
windows, power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire has built up
heat from driving. SeeInation - Tire Pressure
on page 375.
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 (DOT)
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. See
