2-14 Resynchronization
Pressing the transmitter buttons numerous times
(approximately 250 times) out of the vehicle's operating
range may cause the transmitter not to work. Replacing
the battery and pressing the transmitter buttons 10 or
more times out of range will also cause the transmitter
not to work.
To resynchronize the transmitter, you must be within the
vehicle's operating range. Press and hold the lock and
unlock buttons for approximately 5 to 10 seconds.
See your dealer for service if your transmitter still
doesn't work properly.
Trunk
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
65F (18C) and 85F (29C). That will
force outside air into your vehicle. See
ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

3-2
Comfort Controls
This section tells you how to make your air system work
for you.
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)
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.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 clockwise to increase the
temperature and counterclockwise to decrease the
temperature. Pressing this knob puts the climate control
system in an automatic mode. For more information,
see ªAutomatic Operationº later in this section.
Passenger's Side Temperature Knob
The right front passenger can control the temperature
of heated air for his/her own zone, independent from
the driver's temperature setting. The passenger's
temperature can be set anywhere between 60
F (16
C)
and 90
F (32
C).
To turn the system on, press the passenger's side
TEMP/OFF knob. Turn the knob clockwise to increase
temperature and counterclockwise 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.

3-3
Outside Temperature Display
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.
English/Metric 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 five 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
F (16
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.

4-24

Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.

If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.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.
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.

4-38 Parking on Hills
CAUTION:
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:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
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 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 system. 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 ªEngine Overheatingº
in the Index.

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 Fans
CAUTION:
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.

5-12
The coolant level should be at or slightly above the
KALT/COLD line (seam).
You may have a leak in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
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.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL
is not
covered by your new vehicle 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.

5-13 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, drinkable water 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 ªEngine Coolantº in the Index
for more information.
CAUTION:
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.
