5-26 Removing the Wheel Covers (If Equipped)
If your vehicle is equipped with wheel covers, be sure to
use a wheel wrench to begin the process of loosening the
plastic wheel nut caps.
Once you have loosened
the plastic nut caps with
the wheel wrench, if
needed, you can finish
loosening them with
your fingers.
Then, using the flat end of the wheel wrench, pry along
the edge of the wheel cover until it comes off. Be
careful; the edge may be sharp. Don't try to remove the
cover with your bare hands.
Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.
2. Turn the jack handle clockwise to raise the jack
lift head.

CAUTION:
Getting under a vehicle when it is jacked up 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.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the jack
lift head into the proper location before raising
the vehicle.
5. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to fit under
the vehicle.
6. Remove all wheel nuts and take off the flat tire.

5-30
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
10. Tighten the wheel
nuts firmly in a
crisscross sequence

CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and
have the nuts tightened with a torque wrench
to 100 lb
-ft (140 N´m).

Filling Your Tank
CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don't smoke if you're near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.
The tethered fuel cap is located behind a hinged door on
the driver's side of your vehicle.
While refueling, let the fuel cap hang by the tether
below the fuel fill opening.
To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has a spring in it;
if you let go of the cap too soon, it will spring back
to the right.

6-7
CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel cap too quickly. This spray can happen if
your tank is nearly full, and is more likely in hot
weather. Open the fuel cap slowly and wait for
any ªhissº noise to stop. Then unscrew the cap
all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See ªCleaning the
Outside of Your Vehicleº in the Index.When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See ªMalfunction Indicator Lampº
in the Index.
The SERVICE ENGINE SOON or CHECK ENGINE
(Canada) light will come on if the fuel cap is not
properly reinstalled.
NOTICE:
If you need a new fuel cap, be sure to get the
right type. Your dealer can get one for you.
If you get the wrong type, it may not fit properly.
This may cause your malfunction indicator lamp
to light and may damage your fuel tank and
emissions system. See ªMalfunction Indicator
Lampº in the Index.
