Downloaded from www.Manualslib.com manuals search engine City Driving One of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals.
Here are ways to increase your safety

Know the best way to get to where you are going. Get
a city map and plan
your trip into an unknown part of
the city just as you would for a cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next
part, “Freeway Driving.”)
Treat a green light as a warning signal. A traffic light
is there because the corner is busy enough
to need it.
When a light turns green,
and just before you start to
move, check both ways for vehicles that have not
cleared the intersection or may be running the
red light.

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

-1AUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell it,
so you might not
know it is in your vehicle. Clear away
snow from
around the base
of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for
a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Recreational Vehicle Towing
Vehicles with two-wheel drive or the electronic shift
transfer case require special modifications before they
can be towed
in this manner. Please contact your dealer
for the towing information that is appropriate for your
particular vehicle.

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 H-T--- ess
The light duty trailer wir 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 rear 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.
Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps. Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground wire.
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.

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play (1/4 inch to
1/2 inch or 6 rnm to 12 mm) in the pedal is normal.
It isn’t
a good idea to “top off” your clutch fluid. Adding
fluid won’t correct a leak. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule, Owner Checks
and Services, to determine how often you should check
the fluid level in your clutch master cylinder reservoir
and for the proper fluid. See “Owner Checks and
Services” and “Recommended Fluids and Lubricants”
in the Index.
How to Check
The proper fluid should be added if the level does not
reach the bottom
of the diaphragm when it’s in place in
the reservoir. See the instructions on the reservoir cap.

Downloaded from www.Manualslib.com manuals search engine Headlamps Fuses and Circuit Breakers
The headlamp wiring is protected by an internal
circuit breaker. An electrical overload will cause the
lamps to go
on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is
too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away. The
wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace
a bad fuse with a new one of the identical size
and rating.
If
you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as
you can.

Downloaded from www.Manualslib.com manuals search engine At Least Twice a Year Automatic Transmission Check
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are working properly. Look
for any other loose or damaged
safety belt system parts. If you
see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The
air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas
of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission’’ in the Index. Check for leaks.
A fluid loss may indicate a problem. Have the system
inspected and repaired if needed. Check the transmission fluid level; add
if needed. See
“Automatic Transmission” in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid” in the Index. A fluid loss in
this system could indicate a problem. Have the system inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
