Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.
Trunk Lock
To unlock the trunk lid from the outside, insert the door
key into the trunk lock and turn it counterclockwise.
Or, with the vehicle in PARK (P), press the open trunk
symbol on the remote keyless entry transmitter.
Remote Trunk Release
Press the remote trunk
release button located
behind the glove box door
to release the trunk lid
from inside the vehicle.
The shift lever must be in PARK (P), but the key does
not have to be in the ignition for the remote trunk
lid release button to work.

Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the ignition key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the ignition key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in RUN.
The power door locks are activated.
An illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on.
Reading Lamps
The reading lamps are located on the underside of the
rearview mirror. Press the button next to each lamp
to turn it on and off.
Dome Lamp
The dome lamp will come on when you open a door.
Battery Rundown Protection
This helps the vehicle’s battery from draining the battery
in case the interior courtesy lamps, reading lamps,
visor vanity lamps, trunk lamp, underhood lamp or glove
box lamps are left on. If any of these lamps are left
on while the ignition is off, they will automatically turn off
after 20 minutes. The lamps will not come back on
again until you do one of the following:
Turn the ignition on.
Turn the exterior lamps control off, then on.
Open a door.
If the vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.

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.
(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.
(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 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. Lubricate all hinges
and latches, including those for the body doors,
hood, secondary latch, pivots, spring anchor, release
pawl, rear compartment, glove box door and console
door. 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.
(g)If you drive regularly under dusty conditions, the
lter may require replacement more often.
