Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or whatever.
There is something about
an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone
of the engine, and the rush of the wind
against the vehicle that can make
you sleepy. Don’t let it
happen
to you! If it does, your vehicle can leave the
road in less than a secund, and you could crash and
be injured.
What can
you do about highway hypnosis? First, be
aware that
it can happen.
Then here are
some tips:

instruments frequently.

both. For safety. treat drowsiness on the highway as
an
emergency.

planning
to visit there, here are some tips that can make
your trips safer and more enjoyable. (See “Off-Road
Driving’’ in the Index for information about driving

Here are some tips for winter driving:
Have your vehicle in good shape for winter.
0 You may want to put winter emergency supplies in
your vehicle. Include an ice scraper,
a small
brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel,
a flashlight, a red cloth and
reflective warning triangles. And, if you will be driving
under severe conditions, include a
small bag of sand, a
piece of old carpet or a couple of burlap bags to help
provide traction. Be
sure you properly secure these
items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation.
You’ll
have a lot less traction or “grip” and will need to be
very careful.

Downloaded from www.Manualslib.com manuals search engine Driving with a Trailer
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 necessary repairs before
starting on your trip.
0 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 cooling system on and
with the
fan on
any speed. This will bring fresh,
outside
air into your vehicle. Do not use
MAX A/C because it only recirculates the
air inside your vehicle. (See b‘ Comfort
Controls”
in the Index.) 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 as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments). safety chains. electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes. start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets
you check your
electrical connection at the same time.
During your trip. check occasionally to be sure that the
load is secure. and that the lamps and any trailer brakes
are still working.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
The light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver’s
side corner frame crossmember on four-door vehicles.
The heavy-duty trailer wiring has
a 30-amp feed wire
with an inline
fuse located by the junction block. See
“Fuses and Circuit Breakers”
in the Index. Both
harnesses have no 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.
0 Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
0 Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
0 White (Light Gage): 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.

Make sure the tire and carrier are secure.

Compact Spare Tire (If Equipped)
Although the compact spare tire 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).
After installing the compact spare on your vehicle,
you should stop as
soon as possible and make sure
your spare tire
is correctly inflated. The compact
spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
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.
