Use only a hoist or a service jack to
lift the vehicle. Do not use any other
type of jack.
Lifting the Vehicle with a Hoist
To hoist lift, look for the four cutout
areas on the body flange.
Caution
Lifting the vehicle improperly can
damage the vehicle and result in
costly repairs not covered by the
warranty.
1. Front Lifting Points
2. Rear Lifting Points
Access the front lifting points (1) just

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 shift lever inP (Park).
3. Turn off the vehicle.
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,
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.
When using a jack 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
cause damage and result in
costly repairs not covered by the
warranty. Lift the vehicle using
only the lifting pads when lifting
the vehicle with a jack.
Use the lifting pads (1) to properly
lift the vehicle with a service jack.

This vehicle has an airbag system.
Before attempting to do your own
service work, seeAirbag System
Check 073.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records 0326.
Caution
Even small amounts of
contamination can cause damage
to vehicle systems. Do not allow
contaminants to contact the fluids,
reservoir caps, or dipsticks.
Hood
To open the hood:
1. Turn the vehicle off before opening the hood. If the vehicle
is on, the engine will start when
the hood is opened. See
Electric Mode 0176 and
Extended Range Mode 0176.
2. Pull the release handle with
this symbol. It is below the
instrument panel outboard of
the steering wheel.
3. Go to the front of the vehicleand locate the secondary
release lever under the front
left center of the hood. Push
the secondary hood release
lever to the right to disengage. 4. Lift the hood and release the
hood prop rod from its retainer
above the radiator support.
Place the prop rod securely
into the slot in the hood.
To close the hood:
1. Before closing the hood, check that all filler caps are properly
installed. Then, lift the hood to
relieve pressure on the
hood prop.
2. Remove the hood prop from the slot in the hood and return
it to its retainer above the
radiator support. The prop rod
must lock into place when
returning it to the retainer to
prevent hood damage.
3. Lower the hood 20 cm (8 in) above the vehicle and release
it so it fully latches. Check to
make sure the hood is firmly
closed. Repeat the process if
necessary.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0234.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
0 231 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:

cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the surge tank pressure
cap—even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.
If coolant is needed, add the proper
GM Premix DEX-COOL engine
coolant at the coolant surge tank.
The coolant surge tank pressure
cap can be removed when the
cooling system, including the surge
tank pressure cap and upper
radiator hose, is no longer hot. 1. Turn the pressure cap slowly counterclockwise. If a hiss is
heard, wait for that to stop.
A hiss means there is still
some pressure left.
2. Keep turning the cap and remove it.
3. Fill the coolant surge tank withthe proper mixture to the cold
fill line.
4. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
Caution
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.
