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.
0 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.
0 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 can
climb the
hill better.
0 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.
0 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.
0 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.

Downloaded from www.Manualslib.com manuals search engine 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, and 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
See “Trailer Wiring Harness” in the Index.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
! NOTICE:
~ When operating a power winch on your vehicle always leave the \
l transmission in the neutral position. Do not leave an automatic
transmission in
P (Park) or a manual transmission in gear or the
transmission may be damaged.
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.

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.
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.
6-15

Downloaded from www.Manualslib.com manuals search engine Wait at least 30 minutes before checking the transmission fluid level if you
have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 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 transmission fluid hot: Get the vehicle warmed up by driving
about
15 miles (24 km) when outside temperatures are above 50°F (10°C).
If it’s colder than 50°F (lO”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.
To check transmissionfluid 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 (10°C) 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 check,
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
0 Park your vehicle on a level place.
0 With the parking brake applied, place the shift lever in “P’ (Park).
With your foot on the brake pedal, move the shift lever through 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 fluids labeled DEXR0N’-I11 or DEXR0N’-IIE,
because fluids with those labels are made especially for your automatic
transmission. Damage caused by fluids other than DEXRON@-I11 or
DEXRON@-IIE
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back 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 fo 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.

1. Remove the filler (upper) plug.
2. Check that the lubricant level is up to the bottom of the filler plug hole.
3. If the fluid level is good, install the plug and be sure it is fully seated. If
the fluid level
is low, add more fluid as described in the next steps.
