Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out
for the open road, you’ll want to get to know your rig. Acquaint yourself with
the feel of handling and braking with the added weight of the trailer. And
always keep in mind that the vehicle you are driving is now a good deal
longer and not nearly
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety \
chains, electrical
connector, lights, tires and mirror adjustment.
If the trailer has electric brakes,
start your vehicle and trailer moving and then apply the trail\
er brake controller
by hand to be sure the brakes are working. This lets you check your
electrical connection at the same time.
If you have a rear-most window open and you pull a trailer with your
vehicle, carbon monoxide (CO) could come into your vehicle. You
can’t see or smell CO. It can cause unconsciousness or death (see
“Engine Exhaust” in the Index).
To maximize your safety when towing
a trailer:
Have your exhaust system inspected for leaks and make
Keep the rear-most windows closed.
If exhaust does come into your vehicle through a window in the
rear, or another opening, drive with your front, main heating \
or

on and with the fan on any speed. This will
bring fresh, outside air into your vehicle.
Do not use MAX NC

“Comfort Controls” in the Index.
necessary repairs before starting
on your trip.
During your trip, check occasionally to be sure that the load is secure, and
that the lights and any trailer brakes are still working.

Following Distance
Stay at least twice as far behind the vehicle ahead as you w\
ould when
driving your vehicle without a trailer. This can help you avoi\
d situations that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move your hand to the left.
To move the trailer to the
right, move your hand to the right. Always back up slowly and\
, if possible,
have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than n\
ormal. Do this so
your trailer wheels won’t strike soft shoulders, curbs, road \
signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument \
panel will flash
whenever you signal a turn or lane change. Properly hooked up,\
the trailer lights will also flash, telling other drivers you’re about to turn, change lanes,
or stop.
When towing a trailer, the green arrows on your instrument pan\
el will flash for
turns even
if the bulbs on the trailer are burned out. Thus, you may think \
drivers behind you are seeing your signal when they are not. \
It’s important to
check occasionally
to be sure the trailer bulbs are still working.
Driving on Grades
Reduce speed and shift to a lower gear before you start down 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.
You should use
D (or as you need to, a lower gear) when towing a trailer.
Operating your vehicle in
D when towing a trailer will minimize heat buildup
and extend the life
of your transmission.

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.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
shift to
P (Park).
5. Release the regular brakes.
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 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.

Other Warning Devices
If you carry reflective triangles, you can set one up at the sid\

300 feet (1 00 m) behind your vehicle.
Jump Starting
If your battery has run down, you may want to use another vehicle and some
jumper cables to start your vehicle. But please follow the ste\
ps below to
do it
safely.
Batteries can hurt you. They can be dangerous because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you don’t follow these steps exactly, some or all of these things
can hurt you.
Ignoring these steps could result in costly damage to your vehicle that
wouldn’t be covered by your warranty. Trying
to start your vehicle I-
pushing or pulling it won’t work, and it could damage your vehicle.
I
To Jump Start Your Vehicle
1. Check the other vehicle. It must have a 12-volt battery with a negative
ground system.

Page 208 of 345

Downloaded from www.Manualslib.com manuals search engine 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.
1 CAUTION
I
A You could be injured if the vehicles roll. Set the parking brake firmly
b on each vehicle. Put an automatic transmission in P (Park) or a
I manual transmission in N (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
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) and the
negative
(-) terminals on each battery.
1 CAUTION
A Using a match near a battery can cause battery gas to explode.
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 installed
in every new
GM vehicle. But if a battery has filler caps, be sure the
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 in\
sulation. If
they do, you could get a shock. The vehicles could be damaged\
, too.
Before you connect the cables, here are some things you should\
know.
Positive
(t) will go to positive (+) and negative (-) will go to negative
(-) or a metal engine part. Don’t connect (t) to (-) or you’ll get a
short that would damage the battery and maybe other parts,
too.
