A CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the setting
on
AUTO and the temperature between
65°F (18OC) and 85°F (29°C). That will
force outside
air into your vehicle. See
“Comfort Controls” in the Index.

This section tells you how to make your air system work
for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
You can control the heating, cooling and ventilation
systems in your vehicle. Guidelines for using these
systems are found later in this section.
Electronic Climate Control (ECC)
Driver’s Side Temperature Knob
The driver’s side TEMP/AUTO knob adjusts the air
temperature coming through the system. Turn the
TEMP/AUTO knob to the right to increase the
temperature and to the left to decrease the temperature.
Pressing this
knob puts the climate control system in an
automatic mode. For more information, see “Automatic
Operation” later in this section.
Passenger’s Side Temperature Knob
The right front passenger can control the temperature of
heated air for their own zone, independent from the
driver’s temperature setting. The passenger’s
temperature can
be set anywhere between 60 OF (1 6 O C)
and 90°F (32°C).
To turn the system on, press the passenger’s side
TEMP/AUTO knob. Rotate the knob to the right to
increase temperature and to the left to decrease. Pressing
the knob again turns
off the dual-zone function and
returns the system to the one-zone function, where the
driver controls the temperature.
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow
to decrease fan speed.

The outside temperature is always displayed when your
vehicle's ignition is on. If the outside temperature
display begins to flash, this means that icy road
conditions
are possible. Adjust your driving if needed.
The display will flash for about
30 seconds and then
remain on steady.
Mode Button
Press this button to deliver air through the floor, middle
or windshield outlets. The climate control system will
stay in the selected ECC mode until the MODE button is
pressed again or until the TEMP/AUTO knob is pressed.
Press the up or down arrow to see the available modes.
EnglisWetric Display
You can change the temperature display from English
(degrees Fahrenheit) to metric (degrees Celsius) by
pressing and holding the driver's side TEMP/AUTO
knob for approximately three seconds. Repeat the
process to change back to English from metric.
Automatic Operation
Pressing the driver's side TEMP/AUTO knob sets the
system for automatic operation. Once the system is set,
sensors will control the air delivery mode. Air will come
from the floor, middle, side
or windshield outlets. The
fan speed will
vary as the system maintains the selected
temperature setting. (All previous manually set mode
settings will change back to a fully automatic mode
when the climate control system is turned on this way.)
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the
75 "F (24°C)
setting and allow about 20 minutes for the system to
regulate air temperature. Adjust the temperature if
necessary. If you choose
60 OF (1 6 " C), the system will
remain at that maximum cooling setting and will not
regulate fan speed. If you choose the temperature of
90" F (32"C), the system will remain at that maximum
heating setting and will not regulate fan speed. Choosing
either maximum setting will not cause the system to heat
or cool any faster.

Downloaded from www.Manualslib.com manuals search engine 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.
~ A CAUTION:
’ If y!! 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. 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 highway 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.

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
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 the regular brakes, but do not shift into PARK (P).
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 shift into
PARK (P) firmly and apply the parking brake.
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;
Shift into a gear; and
0 Be sure the parking brake has released. Your
vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule booklet
for more on this. Things that are especially important in
trailer operation
are automatic transmission fluid (don’t
overfill), engine
oil, axle lubricant, drive belt, cooling
system and brake adjustment. 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.

Downloaded from www.Manualslib.com manuals search engine If you get the overheat warning with no sign of steam, try this for a minute or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting
3. If you’re in a traffic jam, shift to NEUTRAL (N);
and open the windows, as necessary.
otherwise, shift
to the highest gear while
driving
-- DRIVE (D) or THIRD (3).
If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back
on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.
Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fans

Downloaded from www.Manualslib.com manuals search engine 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.
If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
I
The coolant level should be at or slightly above the
KALTKOLD line (seam). 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.
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.
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.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
KALT/COLD line (seam), add a 50/50
mixture of clean water (preferably distilled) and
DEX-COOL@ coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap, is cool before you do it. (See “Engine
Coolant” in the Index for more information.)
’ A CAUTION: I
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the
cap when the cooling system, including the
coolant surge tank pressure cap, is hot. Wait
for the cooling system and coolant surge tank
pressure cap to cool if
you ever have to turn the
pressure cap.
5-16

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
