Driving with a Trailer (CONT.)
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer 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 panel 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.
Your vehicle has bulb warning .lights.
When you plug trailer lights into your
vehicle’s lighting system, its bulb
warning lights may not let you know if
one
of your lights goes out. So, when
you have trailer lights plugged in, be
sure to check your vehicle and trailer
lights from time to time to be sure
they’re all working. Once you disconnect the trailer lights, the bulb
warning lights again can tell you if one
of your vehicle lights
is out.
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 Wh) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
it’s best to drive in
D instead of (or,
as you need to, a lower gear). This will
minimize heat build-up and extend the
life of your transaxle.

Using a match near a battery
4 L can cause battery gas to
explode. Peopk have been hurt
doing this, and some have been
blinded. Use a flashlight if you need
more light.
Be sure the battery has enough
water. 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. lf it is low, add wafer to take
care of that first. If you don’t,
explcrsive 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
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.
Before you connect the cables, here are
some things you should know. Positive
(+) will go to positive (+) and negative
(-) will go to negative (-) or a metal
engine part.
Don’t connect
(+) to (-) or you’ll get a
short that would damage the battery
and maybe other parts, too.
Fans or other moving engine
A parts can injure you badly.
Keep your hands away
from
moving parts once the engines are
running.
6. Connect the red positive (+) cable to
the positive
(+) terminal of the
vehicle with the dead battery.
Use a remote positive
(+) terminal if
the vehicle has one.

Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 kPa). The compact spare is
made to go up to
3,000 miles
(5 000 Inn), so you can finish your trip
and have
your full-size tire repaired or
replaced where
you want. Of course, it’s
best to replace your spare with a full-
size tire as soon as you can. Your spare
will last longer and be in good shape in
case you need it again. Your anti-lock
brake system warning light may come
on when you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.
Don’t use your compact spare on some
other vehicle.
And don’t
mix your compact spare or
wheel with other wheels or tires. They
won’t fit. Keep your spare and its wheel
together.

The proper fluid should be added if the
level does not reach the bottom of the
diaphragm when it’s

Adding only plain water to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water or the wrong
mix, your engine could get too hot
but you wouldn’t get the overheat
warning. Your engine could catch fire and you or others could be
burned. Use a
50/50 mix of clean
water and a proper antifreeze.
