Emergency Trunk Release Handle
Notice:Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
enabling them to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located on the underside of the trunk lid.
This handle will glow following exposure to light. Pull the
release handle down to open the trunk from the inside.
Liftgate (Hatchback)
{CAUTION:
Exhaust gases may enter the vehicle if it is driven
with the liftgate, trunk/hatch open, or with any
objects that pass through the seal between the
body and the trunk/hatch or liftgate. Engine exhaust
contains Carbon Monoxide (CO) which cannot be
seen or smelled. It can cause unconsciousness and
even death.
If the vehicle must be driven with the liftgate, or
trunk/hatch open:
Close all of the windows.
Fully open the air outlets on or under the
instrument panel.
CAUTION: (Continued)

Immobilizer Operation
The vehicle may have a passive theft-deterrent system.
The immobilizer system prevents the vehicle from
being started by an unauthorized person by isolating the
power supply to the ignition system, the fuel pump
and the fuel injectors.
The system is automatically armed when the key is
removed from the ignition. You do not have to manually
arm or disarm the system.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the key
head that is electronically coded. The correct key will
start the vehicle. An invalid key immobilizes the engine.
If your key is ever damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light ashes or comes on,
there may be a problem with the theft-deterrent system.
Turn the ignition off and try again.If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-87. If the engine still does not
start with the other key, your vehicle needs service.
If your vehicle does start, the rst key may be faulty.
See your dealer/retailer who can have a new key made.
Up to 10 keys may be programmed for the vehicle.
If you lose or damage your keys, only a dealer/retailer
can have new keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart the engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer/retailer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside Assistance.
SeeRoadside Assistance Program on page 7-7.

Content Theft-Deterrent
Your vehicle may have a content theft-deterrent system.
The theft-deterrent system will not arm when you lock
the doors using the key or the manual door lock. It arms
only when you use the remote keyless entry transmitter.
Arming the System
To arm the system, do the following:
1. Close the doors, the windows, the hood, and the
trunk or liftgate.
Make sure that the windows are closed, as the
system can be armed even if the windows are open.
2. Turn the key to LOCK/OFF and remove the
key from the ignition.
If the key is inserted in the ignition, the transmitter
will not arm the theft-deterrent system.3. Lock the doors by pressing the lock button on the
remote keyless entry transmitter.
The LED light on the transmitter will ash once.
All of the doors will lock.
The hazard warning lamps will ash once and
the horn will sound.
The security light will ash continuously to
indicate that the theft-deterrent system is armed.
The security light is located on the center of
the instrument panel near the clock.
To avoid activating the alarm by accident, do one of the
following:
Unlock the driver’s or passenger’s front door using
the key.
Press the unlock button on the remote keyless
entry transmitter.
Unlocking a door any other way will activate the alarm
when a door or the trunk or liftgate is opened.
If you do not want to arm the theft-deterrent system,
lock the vehicle using the key or the manual door locks.

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.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
Towing
Towing Your Vehicle
To avoid damage, the disabled vehicle should be towed
with all four wheels off the ground. Consult your
dealer/retailer or a professional towing service if the
disabled vehicle must be towed. SeeRoadside
Assistance Program on page 7-7.
To tow the vehicle behind another vehicle for
recreational purposes, such as behind a motorhome,
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing the vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle
with two wheels on the ground and two wheels up on a
device known as a dolly.

4. Securely place the hood prop into the slot on the
inner fender.Before closing the hood, be sure all the ller caps are
on properly. Then lift the hood to relieve pressure on the
hood prop. Remove the hood prop from the slot in the
inner fender and return the prop to its retainer. Lower the
hood 12 inches (30 cm) above the vehicle and release
it so it fully latches. Check to make sure the hood is
closed and repeat the process if necessary.

4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the Maximum mark, add more of the proper mixture
to the coolant surge tank until the level reaches
the mark.
5. Replace the pressure cap. Be sure the pressure
cap is hand-tight and fully seated.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.Engine Overheating
The vehicle has an indicator to warn of the engine
overheating.
There is a coolant temperature gage on the instrument
panel cluster. SeeEngine Coolant Temperature
Gage on page 3-31.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
SeeRoadside Assistance Program on page 7-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fan is running.
If the engine is overheating, the fan should be
running. If it is not, do not continue to run the engine
and have the vehicle serviced.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:If the engine catches re because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.

If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, wheel nuts, and TPMS
sensors for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts on your vehicle can be dangerous. It
could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts, and wheel nuts for
replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-70for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how far it
has been driven. It could fail suddenly and cause a
crash. If you have to replace a wheel, use a new
GM original equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class “S” type chains
that are the proper size for your tires. Install them
on the front tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.
