If No Steam Is Coming From Your
Engine
An overheat warning, along with a Check Coolant Level
message, can indicate a serious problem. SeeDIC
Warnings and Messages on page 3-64.
If you get an engine overheat warning with no Check
Coolant Level message, but see or hear no steam, the
problem may not be too serious. Sometimes the
engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the temperature control to the highest heat
setting and open the windows, as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there’s still no sign of steam, you can idle the engine
for three minutes while you’re parked. If you still
have the warning,turn off the engine and get everyone
out of the vehicleuntil it cools down.
You may decide not to lift the hood but to get service
help right away.

4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle. SeeEngine Compartment Overview
on page 5-12for more information on location of 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.

Headlamps, Sidemarker, and
Parking Lamps
If your vehicle has halogen headlamps, you can replace
the bulbs using the following procedure. Use this
procedure to replace the front sidemarker and parking
lamp bulbs also.
If you only need to change the sidemarker bulb, there is
an alternate procedure. SeeSidemarker Lamps on
page 5-57.
To remove the headlamp assembly from the vehicle and
access the bulbs, follow these steps:
1. Open the hood. SeeHood Release on page 5-11
for more information.
2. Use a tool to remove all of the fasteners along the
top surface of the front fascia.
3. Use a tool to remove the one screw and
one retainer on top of the headlamp assembly.
4. Gently pull the front fascia away from the headlamp
assembly and remove the screw attached to the
bracket located at the lower inboard side of
the headlamp assembly.5. Pull the headlamp assembly straight out to
disengage the snap in the retainer at the lower
outboard back surface of the assembly and then
turn the lamp so that the inboard corner clears the
front fascia and pull the lamp out
6. Remove the electrical harness connector from the
back side of the headlamp assembly access cap.
To replace the headlamp high and/or low beam bulb(s),
do the following:
1. Remove the three Torx
®screws on the back of the
access cap.
2. You can now access the low and high beam bulbs.
Turn the low beam (upper) bulb socket
one-eighth turn counterclockwise to remove it from
the assembly. Turn the high beam (lower) bulb
socket one-eighth turn clockwise to remove it from
the assembly.
3. Replace the bulb. SeeReplacement Bulbs on
page 5-58for the proper bulb number.
4. Reinstall the three Torx
®screws while making sure
the access cap seal gasket is located in the access
cap seal channel.

Maintenance 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.
#Lubricate the front suspension, ball joints, steering
linkage, transmission shift linkage and parking
brake cable guides. Ball joints should not be lubricated
unless their temperature is 10°F (-12°C) or higher,
or they could be damaged.
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, cha ng, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose or missing parts,
signs of wear or lack of lubrication. Inspect power
steering lines and hoses for proper hook-up, binding,
leaks, cracks, cha ng, 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 blade inserts 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 air bag
coverings, and have them repaired or replaced. (The air
bag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latch, pivots, spring anchor,
release pawl, hood hinges, body door hinges, rear
compartment hinges and any folding seat hardware.
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.
See Weatherstrips on page 5-96.
