Comfort Controls
With this system, you can control the heating and
ventilation in
your vehicle. If you have the air
conditioning option, you can also control cooling.
Your vehicle also has the flow-through ventilation
system
described later in this section.
Fan Control Knob
Turn the fan knob to select the force of air
you want.
Temperature Control Knob
Turn the center knob to change the temperature of the
air flowing from the heating system. Turn it toward the
red area (clockwise) for warmer air and toward the blue
area (counterclockwise) for cooler
air.
Air Control Knob
OFF’: The system is off.
2 VENT: Air flows through the upper air vents.
12 BI-LEVEL: Air is directed through the upper air
vents and the heater ducts.
ld HEATER: This setting directs most of the air
through the heater ducts and some of the air through the
windshield defroster vents.
‘3 BLEND: Air is directed through the windshield
defroster vents and the heater ducts.
DEFROST: This setting directs most of the air
through the windshield defroster vents and some of the
air through the heater ducts.

Air Conditioning
The air conditioning system uses the same controls as
the heating system, except that the air control knob has
two extra settings, described below.
MAX: Provides maximum cooling or quick cool-down
on very hot days. This setting recirculates most
of the air
inside your vehicle. If it is used for long periods of time,
the
air may become dry. This setting directs air through
the upper
air vents.
A/C: Use for normal cooling on hot days. This
setting cools outside air and directs it through the
upper air vents.
The
air conditioner compressor operates in MAX, NC,
bi-level, blend and defrost when the outside temperature is above
freezing. 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 cooling and help fuel economy.
Cooling
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.
2. Turn the temperature control knob to a

Heater” in the Index.
Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to bi-level.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed. For mild outside temperatures when little heating
or
cooling is needed,
you can still direct outside air through
your vehicle.
1. Turn the air control knob to vent.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your
trips safer and more enjoyable.

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.
ra 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.
A CAUTION: I
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.

0 Shift into a gear; and
0 Release the parking brake.
Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a
hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your
parking brake, and then shift to
PARK (P) for an
automatic transmission, or
REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
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, drive belts, 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
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Cooling Engine Fans
A CAUTION: I
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure
you. Keep hands, clothing and tools
away from any underhood electric fan.
I I
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
5-17

When it is cool, remove the coolant recovery tank cap
and look at the dipstick.
The coolant level should be at
FULL COLD.
If it isn't, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you
do, you can be burned.
Don't run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine
fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
I
Engine damage from running your engine
without coolant isn't covered
by your warranty.
5-18

If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans
are running. If the
engine is overheating, both fans should be running.
If
they aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD add a 50150 mixture of clean water
(preferably distilled) and DEX-COOL@ engine coolant
at the coolant recovery tank. (See “Engine Coolant” in
the Index for more information.)
a CAUTION:
-1
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
