Reduce speed and shift to a lower gear before you start dawn a long or
steep downgrade. If you don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission, you should use “D” when towing a
trailer. Operating your vehicle
in “D” when towing a trailer will minimize
heat buildup and extend the life of your transmission.
Or, if you have a
rrianual transmission with fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start to move. People
can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet, or into

3. When the wheel chocks are in place, release the regular brakes until the

4. Reapply the regular brakes. Then apply your parking brake, and \
then

in a drive gear-not in “N” (Neutral).

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

Jump Starting
If your battery has run down, you may want to use another ve\
hicle and some
jumper cables to
start your vehicle. But please follow the steps below to do
it safely.
NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your warranty.
Trying to start your vehicle by pushing or pulling
it could
damage your vehicle, even
if you have a manual transmission.
And
if you have an automatic transmission, it won’t start that
way.

To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery wlm a\
negauve
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative \
ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other. If they are, it could cause
a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical syst\
ems.
You could be injured if the vehicles roll, Set the parking brake
firmly
on each vehicle. Put an automatic transmission in “P” (Park)\
or a
manual transmission
in “N’ (Neutral). If you have a four-wheel drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N’ (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights t\
hat aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!
I NOTICE:

If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative

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”

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

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.
