If You’re Stuck: In Sand, Mud, Ice or
Snow
What you don’t want to do when your vehicle is stuck is to spin your
wheels. The method known as “rocking” can help you get o\
ut when you’re stuck, but you must use caution.
If you let your tires spin at high speed, they can explode and \
you or I
I-, others could be injured. And, the transmission or other parts of the
vehicle can overheat. That could cause an engine compartment fi\
re or other damage. When you’re stuck, spin the wheels as litt\
le as
possible. Don’t spin the wheels above
35 mph (55 kmlh) as shown
on the speedometer.

Fuels in Foreign Countries
If you plan on driving in another country outside the US. or Canada,
unleaded fuel may be hard
to find. Do not use leaded gasoline. If you use
even one tank full, your emission controls won’t work well \
or at all. With
continuous use, spark plugs can get fouled, the exhaust system \
can corrode,
and your engine
oil can deteriorate quickly. Your vehicle’s three-way catalytic
converter and oxygen sensor will be damaged.
All of that means costly
repairs that wouldn’t
be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company
that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us where
you’re
going and give your Vehicle Identification Number (VIN).

If you get gasoline on you and then something ignites it, you\
could
be badly burned. Gasoline can spray out on you
if you open the fuel
filler cap too quickly. This spray can happen
if your tank is nearly
full, and
is more likely in hot weather. Open the fuel filler cap slowly
and wait
for any “hiss” noise to stop.

When you put the cap back on, turn it to the right (clockwise) until you hear

Engine Block Heater:
An engine block heater can be a big help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If your vehicle has this option, see
“Engine Block Heater” in the Index.
What to Do with Used Oil:
Used engine oil contains things that have caused skin cancer in
laboratory animals. Don’t let
used oil stay on your skin for very long.

Used oil can be a real threat to the environment. If YOU change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t ever
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.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your automatic transmission fluid level is when the
engine
oil is changed. Refer to the Maintenance Schedule to determine when
to change your fluid. See “Scheduled Maintenance Services” in \
the Index.
How to Check:
Because this operation can be a little difficult, you may choose to have this
done at a General Motors dealership Sewice Department.
If you do it yourself, be sure to follow all the instructions here, or you could
get
a false reading on the dipstick.
NOTICE I
I
Too much or too little fluid can damage your transmission. Too much can
mean that some of the fluid could come out and fail
on hot engine parts,
I
starting a fire. Be sure to get an accurate reading if you check-your
transmission fluid.
Wait at least
30 minutes before checking the transmission fluid level if you
have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather.
While pulling a trailer.
