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.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a
hill. You could crash. Shift down to let your
engine assist your brakes on
a steep
downhill slope.
A CAUTION: . -.
Coasting downhill in NEUTRAL (N) or with the
ignition
otf is dangerous. Your brakes will have to
do all the work
of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when
you go downhill.
0 Know how to go uphill. You may want to shift down to a
lower gear. The lower gears help cool yo~~r 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.
You may see highway signs on nmuntains 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
I, Apply your reg~~lar brakes and lwld 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 nlore 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. ~~xle lubricant, belt, cooling system
and
brakc adjustment. Each of these is covered in this
manurd.
and the Index will help you find then] 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.

Automatic Transmission Fluid
Operating the engine with the air cleaner off can
cause you or others
to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires.
If it isn't there, and the engine
backfires, you could be burned. Don't drive with
it
off, and be careful working on the engine with
the air cleaner
off.
I 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.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid
and filter every 50.000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi. police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See "Scheduled Maintenance Services"
in the Index.

How to Check
Because this operation can be a little difficult, you may
choose to hm;e this done at your
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 parts, 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:
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.
0 While pulling a trailer.
To get the right reading, the fluid slwuld be at normal
operating temperature. which
is 180°F to 200°F (82°C
to 93°C).
Checking 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 ( IOOC), drive the
vehicle
in DRIVE (D) until the engine temperature gage
rnoves and then remains steady for
10 minutes. Then
follow the hot check procedures.
6-15

Checking Transmission Fluid Cold
A cold check is made after the vehicle hus been sitting
for eight hours or
Inore with the engine off and is lwd
only as a reference. Let the engine run rlt idle for five
minutes
if outside temperatures are 50°F ( 10°C) oI
more. If it’s colder than 50°F ( IOOC), you may have to
idle the engine longer. Should the fluid level be low
during a cold check, you rrlwst perfor111 a hot check
before adding fluid. This
will give you a more accurate
reading
of the fluid level.
Checking the Fluid Hot or Cold
Park your vehicle on a level place. Keep the
engine running.
With the parking brake applicd. place the shift le\;er
in PARK (P).
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 shit’t
lever
in PARK (P).
Let the engine run at idle for three minutes or more.
I. Flip the handle LIP and then pull out the dipstick and
wipc it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
6-16

3. Check both sides of the dipstick. and read the lower
level.
The fluid level must be in the COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level 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.
Add fluid
only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.) If
the fluid level is low, add only enough of the proper
tluid
to bring the 1wel up to the HOT area for a hot
check.
It doesn't take much fluid. generally less than
one pint (0.5 L). Ih f o\*erfi//.
NOTICE:
We recomnlend you use only fluid labeled
DEXRON@-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused
by fluid other than DEXRON-111
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 YOLK manual
transmission doesn't require changing.
How to Check
Because this operation can be a little dii'licult, you
may choose to have this done at your GM dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get
false reading.
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 parts, starting a
fire. Be
~ sure to get an accurate reading if you check your
~ transmission fluid.
