California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
electronic keys, may contain
perchlorate materials. Perchlorate
Material–special handling may
apply. See www.dtsc.ca.gov/
hazardouswaste/perchlorate.
Accessories and
Modifications
Adding non-dealer accessories or
making modifications to the vehicle
can affect vehicle performance and
safety, including such things as
airbags, braking, stability, ride and
handling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. These accessories or
modifications could even cause
malfunction or damage not covered
by the vehicle warranty. Damage to suspension components
caused by modifying vehicle height
outside of factory settings will not be
covered by the vehicle warranty.
Damage to vehicle components
resulting from modifications or the
installation or use of non-GM
certified parts, including control
module or software modifications, is
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed to
complement and function with other
systems on the vehicle. See your
dealer to accessorize the vehicle
using genuine GM Accessories
installed by a dealer technician.

Adding Equipment to the
Airbag-Equipped Vehicle 072.
Lifting the Vehicle
{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the transmission inP (Park).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack, (Continued)

212 Vehicle Care
Warning (Continued)
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle or the vehicle
may fall and cause injury to you
or others.
If a jack is used to lift the vehicle,
follow the instructions that came
with the jack, and be sure to use the
correct lifting points to avoid
damaging the vehicle.
Caution
Lifting the vehicle improperly can
damage it and result in costly
repairs not covered by the vehicle
warranty. To lift the vehicle
properly and prevent vehicle
damage: . Be sure to place a block or
pad between the jack and
the vehicle.
. Lift only in the areas shown
in the following illustrations.
For additional information, see
your dealer and the service
manual.
Caution
The front jack pads must not
contact the rocker panels, the
front fenders, or the floor pan.
If they do, damage may occur. Lifting from the Front
–Frame
Use only a service jack with a lifting
pad diameter of 64 mm (2.5 in) or
smaller, and thick enough to make
sure the jack does not contact the
vehicle body.
Position the service jack and lifting
pad under the frame rail shipping
slot reinforcement.

How to Add Coolant to the
Coolant Surge Tank
{Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.If coolant is needed, be sure the
cooling system is cool, then add the
proper DEX-COOL coolant mixture
directly to the surge tank.
1. Open the Hatch/Trunk. See Hatch (Trunk) 023.
2. When the cooling system,
including the coolant surge
tank pressure cap and engine,
is no longer hot, remove the
pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left.
3. Keep turning the pressure cap slowly, and remove it.
4. Fill the coolant surge tank withthe proper mixture until the
level inside stabilizes at the
COLD FILL indicator in the
surge tank.
5. With the coolant surge tank pressure cap off, start the
engine and let it run until the
engine is hot.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level stabilizes at
the COLD FILL indicator in the
coolant surge tank.

Electrical System
Electrical System
Overload
The vehicle has fuses to protect
against an electrical system
overload.
Fuses protect power devices in the
vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by
fuses. This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers are
marked with their ampere rating.
Do not exceed the
specified amperage rating when
replacing fuses and circuit
breakers. Use of an oversized
(Continued)
Danger (Continued)
fuse or circuit breaker can result
in a vehicle fire. You and others
could be seriously injured or
killed.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
Instrument Panel Fuse
Block
The instrument panel fuse block is
behind the glove box. The glove box
can be accessed by unlatching the
door damper and squeezing the
pivot to release the damper ring.
Pull the glove box bin side walls in
