Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet
road,
you can't stop. accelerate or turn as well because
your tire-to-road traction
isn't as good as on dry roads.
And,
if your tires don't have much tread left, you'll get
even less traction. It's always wise to go slower and be
cautious
if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving
on dry pavement.
The heavier the rain, the harder
it is to see. Even if your
windshield wiper blades are
in good shape, a heavy rain
can make it harder to see road signs and traffic signals,
pavement markings, the edge
of the road and even
people walking.
It's wise
to keep your wiping equipment in good shape
and keep your windshield washer tank filled with
washer hid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield. or when strim of rubber start to separate
from the inserts.

At the entrance, there is usually a ramp that leads to the
freeway.
If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try to determine where you expect to
blend with the
flow. Try to merge into the gap at close to
the prevailing speed. Switch
on your turn signal, check
your mirrors and glance over your shoulder as often as
necessary. Try to blend smoothly with the traffic flow.
Once
you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate
if it’s slower. Stay
in the right lane unless
you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving on
the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the
next exit. The
exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think
you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes
you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts
in
GM retail facilities all across North America. They’ll be
ready and willing to help if you need it.

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;
0 Shift into a gear; and
0 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
and 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 Wiring Harness
The trailer wiring harness is an eight-wire harness
assembly. The harness
is stored under the vehicle, on the
driver's side corner frame crossmember. The harness has
a 30-amp feed wire
with an inline fuse located by the
junction block. See "Fuses and Circuit Breakers"
in the
Index. The harness does not have
a connector and
should be wired by
a qualified electrical technician. The
technician can use the following color code chart when
connecting
the wiring harness to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
Red: Use for battery charging; it connects to the
starter solenoid.
Light Green: Back-up lamps.
Brown: Tdillarnps and parking lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gauge): Ground wire.
White (Light Gauge): Auxiliary stoplamp.
Securely attach the harness to the trailer, then tape
or strap it to your vehicle's frame rail. Be sure you leave
it loose enough so the wiring doesn't bend or break, but
not
so loose that it drags on the ground. Store the
harness
in its original place. Wrap the harness together
and tie
it neatly so it won't be damaged.
