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 esp\
ecially important in trailer operation are automatic transmission fluid (don’t ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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
Use the regular brakes, set the parking brake Or UIWK ihe wheels IW keep
your vehicle from rolling.

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.
1 CAUTION
* You could be injured if the vehicles roll. Set the parking brake \
firmly I
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 tra-fer case is not in
N (Neut--’).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
I
needed, and radios. This will avoid sparks and help save both \
batteries.
And it could save your radio!
4. Open the hoods and locate the batteries. Find the positive (t) arlu
negative
(-) terminals on each battery.
* Using a match near a battery can cause battery gas to explode. I
People have been hurt doing this, and some have been blinded. \
Use
a flashlight if you need more light.
You don’t need to add water to the Delco Freedom@ battery \
installer’
in every new
GM vehicle. But if a battery has filler caps, be sure thG
right amount of fluid is there.
If it is low, add water to take care of
that first.
If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t get it on you.
If
you accidentally get it in your eyes or on your skin, flush the place
I with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged, too.

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 de\
termine 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 choo\
se to have this
done at a 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
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 must 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 then 50°F (IO’C), drive the vehicle in D (3rd gear) until the
temperature gage moves and then remains steady for ten minutes.\
Then
follow the hot check procedures.
To 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 (10°C) or more. If it’s colder than 50°F (lO°C), you
may have to idle the engine longer. A hot check must follow when fluid is
added during a cold check.

If you have a 4.3L engine, you will have a flip-top handle. Flip\
the
handle up and then pull out the dipstick and wipe it clean with a rag or
paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again. Flip top handle should remain in open position.

PO1 65
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 where it should be, push the dipstick bac\
k in all the
way.
If you have a flip-top handle, flip the handle down to lock it 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 c\
heck. It
doesn’t take much fluid, generally less than a pint. Don’\
t overfill. We
recommend you use only fluid labeled DEXRON@lIE, because fluids \
with that
label are made especially for your automatic transmission. Damag\
e caused by
fluid other than 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 ba\
ck in all the
way. Flip the handle down
if you have a flip-top handle.
