Downloaded from www.Manualslib.com manuals search engine Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. These parts can \
work
hard on mountain roads.
Know how to go down hills. The most important thing to know is this:
let your engine do some of the slowing down. Shift to a lower gear
when you go down a steep or long hill.
Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you ca\
n
climb the hill better.
Stay in your own lane when driving on two-lane roads in hills or
mountains. Don’t swing wide
or cut across the center of the road. Drive
at speeds that
let you stay in your own lane.
As you .go over the top of a hill, be alert. There could be something in
your lane, like a stalled
car or an accident.
You may see highway signs on mountains that warn of special
problems. Examples are long grades, passing or no-passing zones, a
falling- rocks area, or winding roads. Be alert to these and \
take
appropriate action.

When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, an\
d brake
adjustment. Each
of these is covered in this manual, and the Index will help
you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you
start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
Trailer Light Wiring

cover tabs
are fully inserted into the slots in the air cleaner housing and the
PCV air tube is properly seated in the left hand valve cover.
Refer to
the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.
NOTICE:
If’ the air cleaner is off, a backfire can cause a damaging engine
fire.
And, dirt can easily get into your engine, which will damage
it. Always have the
air cleaner in place when you’re driving.
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
GM dealership Service Department.
If you
do it yourself, be sure to follow all the instructions here, or you \
could
get a false reading on the dipstick.

I NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system, 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.
To get the right reading, the fluid should be at normal operating\

temperature, which is 180°F to 200°F (82°C to 93°C).
To check transmissionfluid hot: Get the vehicle warmed up by driving
about 15 miles (24
km) when outside temperatures are above 50°F (10OC).
If it's colder than 50°F (10" C), drive the vehicle in "D" (3rd Gear) until the
engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.
Tu check transmission fluid cold: A cold check is made after the vehicle has
been sitting for eight hours or more with the engine off and is used only as \
a
reference. Let the engine run at idle for five minutes if outside temperatures
are
50°F (10OC) or more. If it's colder than 50°F (lO"C), you may have to
idle the engine longer. Should the fluid level be low during a cold ch\
eck,
you
must perform a hot check before adding fluid. This will give you a\

more accurate reading of the fluid level.
To check the fluid hot or cold
Park your vehicle on a level place.
With the parking brake applied, place the shift lever in "P' (Park).
With your foot on the brake pedal, move the shift lever throu\
gh each
gear range, pausing
for about three seconds in each range. Then,
position the shift lever in
"P' (Park).
Let the engine run at idle for three minutes or more.

is in the
acceptable range,
push the dipstick
back in all the
way; then flip the
handle down to
lock the dipstick
in place.
How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants”
in the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level up to the COLD area for a cold check or the
HOT area for a hot check.
It doesn’t take much fluid, generally less than a pint.
Don’t overfill. We
recommend you use only fluid labeled DEXRON@-I11 or DEXRON@-IIE,
because fluids with that label are made especially for your automatic
transmission. Damage caused by fluid other than DEXRON@-I11 or
DEXR0N’-IIE is not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as described under “How to
Check.”
0 When the correct fluid level is obtained, push the dipstick ba\
ck in all
the way; then flip the handle down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid in your manual transmission
doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at a
GM dealership Service Department.
If you do it yourself, be sure to follow all the instructions\
here, or you could get a false reading.
