RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of three rotary control knobs.
NOTE: For the HVAC to operate efficiently and reduce
the possibility of fog build up on the interior of the
windows, the air exhausters should be kept clear at all
times. The air exhausters are the slots located on the rear
tailgate.
Heater Only — If Equipped
In snowy weather, always clear the air inlet grille at the
base of the windshield before driving your vehicle.
Manual Heater Control
172 UNDERSTANDING YOUR INSTRUMENT PANEL

Mix Outside air comes from the floor and defrost out-
lets. This mode works best in cold or snowy con-
ditions. It allows you to stay comfortable while
keeping the windshield clear.
Defrost Outside air comes from the windshield outlets
with a small amount being directed through the
floor outlets. Use this setting when necessary to defrost
your windshield.
NOTE: For improved safety, the A/C compressor is
activated when “Mix” or “Defrost” modes are selected.
This is done to assist in drying the air and it will help in
keeping the windshield from fogging.Operating Tips
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use lower blower speeds until the engine
warms up. When operating the system during the winter
months, make sure the air intake, located directly in front
of the windshield, is free of ice, slush, snow, or other
obstructions.

10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the normal starting procedure.Extreme Cold Weather (below –20°F or –29°C)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
If Engine Fails to Start
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while cranking the
engine. This should clear any excess fuel in case the
engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
Ignition Key Positions
STARTING AND OPERATING 183

If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” or “Extreme Cold
Weather” procedures should be repeated.
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
After Starting
The idle speed will automatically decrease as the engine
warms up.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord. The engine block
heater cord is found under the hood clipped to the tie rod
between the radiator grille and the dash panel.
184 STARTING AND OPERATING

WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
TRANSMISSION SHIFTING
6-Speed Manual Transmission
Follow the shift pattern on the gearshift knob.
NOTE: The backup lights will come on when your
vehicle is in reverse gear and the ignition is in the ON
position.Manual Shift Controls

Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE: With extended use, the flasher may wear down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in N
(Neutral), but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
Control to maximum heat, the Mode Control to floor, and
the Fan Control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.

Set the parking brake, place an automatic transmission in
P (Park) (or N (Neutral) for a manual transmission). Turn
off lights, heater, and other electrical loads. Observe
charge indicator in the battery. If indicator is light or
yellow, replace the battery.
CAUTION!
Use the “Jump Starting” procedure only when the
charge indicator is dark in the center. Do not attempt
jump starting when the battery charge indicator is
bright or yellow. If the charge indicator is dark and
has a green dot in the center, failure to start is not
due to a discharged battery and the cranking system
should be checked.
1. Attach one end of the jumper cable to the positive
terminal of the discharged battery and the other end of
the same cable to the positive terminal of the booster
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
2. Connect one end of the other jumper cable to the
negative terminal of the booster battery. Connect the
other end of the jumper cable to a good ground on the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
•Store the removed IOD fuse in the Power Distribution
Center location #11 labeled “IOD Storage.”
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
