unconsciousness and even death.
If you must drive with the rear window, endgate
or liftgate open or
if electrical wiring or other
cable connections must pass through the seal
between the body and the rear window, endgate
or liftgate:
Make sure all windows are shut.

XlAX A/C: This setting provides maximuM cooling
with the least amount of work. MAX A/C recirculates
much
of the air inside your vehicle so it cools quickly.

+’ HEATER: This setting directs warmed air through
the heater floor outlets and windshield defroster outlets.
‘H BLEND: Airflow is divided equally between the
heater floor outlet and the windshield defroster outlets.
DEFROST This setting directs most air through
w.
the windshield defroster outlets and some through the
heater outlets.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner
to work its best.
For quick cool-down
on very hot days, use MAX A/C
with the temperature knob turned counterclockwise.
This setting should be used to keep odors and/or dust
from entering the vehicle. For normal cooling on
hot days, use
A/C with the temperature knob
turned counterclockwise. On
cool but sunny days, use BI-LEVEL
A/C to deliver
warm
air to the floor and cooler air to the instrument
panel outlets.
When
the air conditioner is on, you may sometimes
notice slight changes in your vehicle‘s engine speed and
power. This is normal because the system is designed
to cycle
the compressor on and off to keep the
desired temperature.
Heating
The heater works best if you keep your windows closed
while using
it. On cold days, use HEATER with the
temperature knob turned clockwise. BLEND is useful
in
cool weather when you have fog or ice on the
windshield
or side windows.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer
air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.

ror mild outside temperatures when little heating or
cooling is needed. use VENT to direct outside air
through your vehicle.
Airtlow is through the instrument
panel outlets.
Your vehicle's ventilation system supplies outside air- to
the inside
of yo11r vehicle when it is moving. When the
vehicle
is not moving. you can get outside air to flow
through
by selecting any mode and any fan speed.
You
will find air outlets in the center and on the sides of
your instrument panel. You
can move the
outlets to direct the flow of air, or
close the outlets altogether. When you close an outlet. it
will increase the flow of air coming out of my outIets
that are open.

At fast speeds, water splashes
on your ignition system
and your vehicle can stall. Stalling can also occur if you
b get your tailpipe under water. And, as long as your
tailpipe is under water, you’ll never be able
to start your
engine. When
you go through water, remember that
when your brakes get wet, it may take you longer
to stop.
I A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving throwh water.
After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis or under the hood. These
accumulations can be
a fire hazard.
After operation in mud or sand, have
the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure.
steering, suspension, wheels, tires and exhaust system
for damage. Also, check the fuel lines and cooling
system for any leakage.
Your vehicle will require more frequent service due
to
off-road use. Refer to the Maintenance Schedule for
additional information.

Downloaded from www.Manualslib.com manuals search engine Keep your vehicle in good shape. Check all fluid
levels and
also the brakes, tires. cooling system and
transmission. These parts can work hard
on
mountain roads.
Know how to go down hills. The most important
thing
to know is this: let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
A CAUTION:
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a
hill.
You could crash. Shift down to let your
engine assist your brakes on a steep
downhill slope.
I A CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work
of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.
Know how to go uphill. You may want to shift down to a
lower gear. The lower gears help cool your engine and
transmission. and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads
in hills or mountains. Don‘t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something
in your lane. like a. stalled car or an accident.
You may see hishway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones.
a falling rocks area or winding
roads.
Be alert to these and take appropriate action.

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.

Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
whiie you:
Start your engine:
Shift into a gear: and
Release the parking brake.
3,. 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.
