When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
Resynchronizing Your Remote Keyless
Entry Transmitter
Your Keyless Entry System uses a continually changing
code for increased security. Normally, the receiver in
your vehicle will keep track
of this changing code.
0 Loss of synchronization will occur if the transmitter
is activated more than 256 times while out of range
of the vehicle.
Loss of synchronization will occur after battery
replacement
if the transmitter is immediately
activated more than
16 times while Out of range
of the vehicle.
If your key chain transmitter has stopped working, you
may need to resynchronize the transmitter to the vehicle
receiver.
To do this, press the LOCK and UNLOCK
buttons
together and hold for at least seven seconds, or
until the horn sounds when equipped with Content
Theft-Deterrent. Check transmitter.
It can be dangerous to drive with the trunk 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 open or if
electrical wiring
or other cable connections must
pass through the seal between the body and
the trunk:
Make sure all windows are shut.

Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition
key
is turned on, the LOW
OIL
LEVEL light will
briefly flash. If the light
does not flash, have it fixed
so it will be ready to warn
you if there’s
a problem.
Engine Coolant Temperature Light
TEMP
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
If the light stays on, stop th’e vehicle on a level surface
and
turn the engine off, Check the oil level using the
engine oil dipstick, (See “Engine Oil” in
the Index.)
The
oil level monitoring system only checks oil level
during the brief period between key ‘on and engine
crank. It
does not monitor engine oil level when the
engine
is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation to drain back into the oil pan.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do.
See “Engine Overheating” in the Index.

through the ducts near the floor. The remaining airflow
comes out of the defroster and side window vents.
4' DEFOG: This setting allows half of the air to go

window vents.
w.
DEFROST This setting directs most of the
air through the defroster vent. Some of the air goes
to the floor ducts and the side window vent. The air
conditioning compressor will run automatically in
this setting unless the outside temperature is below
38°F (3.3"C).
Air Conditioning COI - --- -1r Button
Press the A/C button to operate the air conditioning
compressor. The indicator light above the button will
glow when the button is pressed. ,You don't have to press
the button
to run the compressor in MAX or DEFROST
because
it will already be running in these modes.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle
to cool down.
For quick cool-down on very hot days, use
MAX with
the temperature knob all the way in the blue area.
If this
setting is used
for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use UPPER with the
temperature knob in the blue area and the
A/C button
pushed in. The system will bring in outside
air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob in
the middle and the A/C button pushed in. The system
will bring in outside air and direct it to your upper body,
while sending slightly warmed air to your lower body.
You may notice this temperature difference more at
some times than others.

Ventilation
For mild outside temperatures when little heating or
cooling is needed, use UPPER, with the AK button off,
to direct outside air through your vehicle. Your vehicle
also has the flow-through ventilation system described
later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use
DEFOG.
Air Conditioning with Automatic and
Auxiliary Temperature Control
(If Equipped)
With this system, you set a “desired cabin” temperature.
You can then either let the system automatically
control
airflow direction and amount (to maintain the desired
cabin temperature)
or you can manually adjust it. The
system works best
if you keep your windows closed
while using it.
