Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The electrical cord is located on the
driver’s side of the engine compartment.
3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and some
other things. Instead of trying to list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

Hood Release
To open the hood, do the following:
1. Pull the hood release
handle with this
symbol on it. It is
located under the
instrument panel on
the driver’s side of
the vehicle.2. At the front of the vehicle, pull up on the
center of the hood, and push the secondary
hood release to the right.
3. After you have partially lifted the hood, gas
struts will automatically take over to lift and
hold the hood in the fully open position.
Before closing the hood, be sure all ller caps are
on properly. Then, pull the hood down to close.

Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed
to prevent coolant loss and possible engine
damage from overheating. Be sure the arrows
on the cap line up with the overow tube on the
radiator ller neck.
SeeEngine Compartment Overview on page 364
for more information on location.
Engine Overheating
You will nd a coolant temperature warning and a
coolant temperature gage on your vehicle’s
instrument panel. SeeEngine Coolant Temperature
Warning Message on page 227andEngine Coolant
Temperature Gage on page 221.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Turn it
off and get everyone away from the
vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when the vehicles
engine is overheated, the liquids in it can
catch re. You or others could be badly
burned. Stop your engine if it overheats,
and get out of the vehicle until the engine
is cool.
SeeOverheated Engine Protection
Operating Mode on page 380for
information on driving to a safe place
in an emergency.

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty. Always
turn off your radio and other accessories when
jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the
cigarette lighter or the accessory power
outlet(s). Turn off the radios and all lamps that
are not needed. This will avoid sparks and help
save both batteries. And it could save the radio!
4. Open the hood on the other vehicle and locate
the positive (+) and negative (−) terminal
locations on that vehicle.
You will not need to access your battery for
jump starting. Your vehicle has a remote
positive (+) jump starting terminal for that
purpose. The terminal is located under a
tethered cap at the front of the underhood fuse
block. SeeEngine Compartment Overview on
page 364for more information on location.Squeeze the tabs and
swing the cap out of the
way to access the
remote positive (+)
terminal.
You should always use the remote positive (+)
terminal instead of the positive (+) terminal
on the battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.

Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 404.
For any bulb changing procedure not listed in this
section, contact your dealer.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas
inside and can burst if you drop or
scratch the bulb. You or others could be
injured. Be sure to read and follow the
instructions on the bulb package.
Headlamps, Front Turn Signal,
Sidemarker, and Parking Lamps
1. Open the hood. SeeHood Release on
page 363for more information.
2. Push in on the
headlamp panel and
lift up the headlamp
retaining clip
partway, but do
not remove.
3. Remove the wing stud on the upper, outboard
side of the lamp assembly.
4. Unsnap the headlamp assembly by pulling it
forward, away from the vehicle.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers, and fusible thermal links.
Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse. Be
sure you replace a bad fuse with a new one of the
identical size and rating.
If you ever have a problem on the road and do not
have a spare fuse, you can borrow one that has the
same amperage. Just pick a feature of your vehicle
that you can get along without – like the radio or
cigarette lighter - and use its fuse, if it is the right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the oor
console fuse block and the underhood fuse and
relay center.
Floor Console Fuse Block
The oor console fuse block is located to the left
of the glove box near the oor. Pull the door
open to access the fuse block.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check
parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, and liftgate hinges. More
frequent lubrication may be required when
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth
will make them last longer, seal better, and not
stick or squeak.
