stops), wait
15 seconds and start over.
When the engine starts, let go of the key and
the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see,
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Coolant Heater (If Equipped)
In very cold weather, 0°F (- 1 SOC) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located
on the driver’s side of the engine
compartment, behind the underhood fuse block.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire.
You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don’t,
it could be damaged.

Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here,
we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
Your automatic transmission may have a shift lever
located on the console between the seats
or on the
steering column.
There
are several different positions for your shift lever.
If your vehicle is equipped with a column shift lever, it
features an electronic shift position indicator within the
instrument cluster. This display must be powered
anytime the shift lever is capable
of being moved out of
PARK (P). This means that if your key is in OFF, but
not locked, there will be
a small current drain on your
battery which could discharge your battery over a period
of time. If you need to leave your key in the ignition in
OFF for an extended period, it is recommended that you
disconnect the battery cable from the battery to prevent
discharging your battery. PARK
(P): This
locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever is
not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You
or others could be injured. To be sure your
vehicle won’t move, even when you’re on
fairly
level ground, always set your parking brake and
move the shift lever to PARK
(P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a nailer’’ in
the Index.

Downloaded from www.Manualslib.com manuals search engine With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and floor outlets. On bright
sunny days in cool weather, the airflow may come out of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most
normal conditions.
If your vehicle
is sitting out on a warm day and you
have the fan set
on AUTO, the air will first flow out of
the floor air outlets for a few seconds. That is normal.
This
is to expel hot air from the air outlets. As the air is
cooled, the airflow will move through the air
conditioning outlets. Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode

RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. In the AUTO mode, the system
will use
recirculation as necessary
to cool the air. Pressing the
recirculation button
will change the operation to a
manual mode and the air will recirculate non-stop. Press
this button again to turn off the recirculation feature. RECIRCULATION may be selected

inside the vehicle when the A/C light
is on.
Air conditioning
will be automatically disabled when
the outside temperature drops below a level which air
conditioning is ineffective.
Remember that
in order for the automatic system to perform
well,
it needs A/C to provide cooling performance.

Downloaded from www.Manualslib.com manuals search engine 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 to the left. 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 to the left.
On vehicles equipped with the Electronic Climate
Control system, this same performance can be achieved
as long as the A/C is enabled and the outside air button
is not active.
Heating
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.
The heater works best if you keep your windows closed
while using it. On cold days,
use HEATER with the
temperature knob turned
to the right. 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.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside
of your 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.

Downloaded from www.Manualslib.com manuals search engine You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side-to-side by rotating the
thumbwheel located in the center of the vent. The vent
can be tilted
up and down also. To control the amount of
airflow through the outlets, rotate the thumbwheel
below the vent.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such
as leaves). The heater
and defroster will work far better, reducing the
chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, move the
fan control to high for
a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
objects. This helps air to circulate throughout
your vehicle.
Keep the air path under the front seats clear of
Defogging and Defrosting
On cool, humid days, use BLEND to keep the
windshield and side windows clear.
Use DEFROST to remove fog or ice from the
windshield quickly in extreme humid or cold conditions.
Turn the temperature knob to the right and move the fan
control toward high.
