Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front and
rear turn signal lamps will flash on and off.
The hazard warning flasher
button is located on top of
the steering column.
Your hazard warning flashers work no matter what
position your key is in, and even if the key isn't in.
Press the button to make the front and rear turn signal
lamps flash on and off. Press the button again to turn
the flashers off.
When the hazard warning flashers are on, the turn
signals won't work.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind
your vehicle.

5-29 Removing the Flat Tire and Installing
the Spare Tire
1. If there is a wheel cover, loosen the plastic nut caps
with the wheel wrench. They won't come off. Then,
using the flat end of the wheel wrench, pry along the
edge of the cover until it comes off. Be careful; the
edges may be sharp. Don't try to remove the cover
with your bare hands.
If your vehicle has aluminum wheels, remove the
wheel nut caps using the wheel wrench.
2. Loosen the wheel
nuts
-- but do not
remove them
-- using
the folding wrench.
(Turn the handle about
180 degrees, then flip
the handle back to
the starting position.
This avoids taking the
wrench off the lug nut
for each turn.)For wheels with a wheel lock key, use the wheel lock
key between the lock nut and folding wrench. The key
is supplied in the front passenger door pocket.
NOTICE:
To help avoid damage to lock nut or wheel lock
key, do not use an impact wrench with this key.
3. Near each wheel,
there is a notch in
the vehicle's body.
Position the jack and
raise the jack head
until it fits firmly
into the notch in the
vehicle's frame nearest
the flat tire.

If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.
How to Reset the Change Engine Oil Message
The GM Oil Life System
calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to a change
engine oil message being turned on, reset the system.
If your vehicle does not have the optional Driver
Information Center (DIC), do the following:
1. With the ignition key in ON but the engine off,
fully push and release the accelerator pedal slowly
three times within five seconds.
2. Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back
on, the engine oil life monitor has not reset. Repeat
the procedure.
If your vehicle has the optional DIC, do the following:
1. Turn the ignition to ON with the engine off.2. Press the MODE button until the DIC reads OIL
LIFE LEFT/HOLD SET TO RESET.
3. Press and hold the SET button until 100%
is displayed.
You will hear three chimes and the CHANGE
ENGINE OIL message will go off. If the CHANGE
ENGINE OIL message comes back on, the monitor
has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly throw away clothing or rags
containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or
into streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have
a problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.

6-29 How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
When the engine compartment is hot, the level should be
at the H (hot) mark. When it's cold, the level should be
at the C (cold) mark. If the fluid is at the ADD mark,
you should add fluid.
What to Use
To determine what kind of fluid to use, see
ªRecommended Fluids and Lubricantsº in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing. See ªEngine Compartment
Overviewº in the Index for reservoir location.
Adding Washer Fluid
The windshield washer fluid
reservoir is located in the
engine compartment on the
passenger's side of the
vehicle, near the fuse and
relay center.
Open the cap with the washer
symbol on it. Add washer
fluid until the tank is full.
