2-9 Resynchronization
Pressing the remote keyless entry 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 out of range will also cause the
transmitter not to work. If only the fuel door button
works, the transmitter needs to be resynchronized to the
receiver. Do this by pressing and holding both the
LOCK and UNLOCK buttons on the transmitter for
about eight seconds. You must be within range of
the vehicle.
Once the transmitter has been resynchronized, the horn
will chirp and the exterior lamps will flash once. The
system should now operate properly. See your dealer
for service if your transmitter 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.

2-71
If this message appears and stays on while driving or
after starting your vehicle, have it checked immediately
to determine the cause of this problem. To help the
generator recharge the battery quickly, you can reduce
the load on the electrical system by turning off the
accessories. You can monitor battery voltage on the DIC
by pressing the INFO (SKIP) button. The normal range
is 11.5 to 15.5 volts.
BRAKE VACUUM PROBLEM
-108: The circuit in
the brake booster vacuum has shorted or is loose when
this message appears. Your vehicle may lose power
brakes but you will still have the use of manual brakes.
The power brakes will not be affected if the problem is
caused by a failed sensor. Have your vehicle serviced
immediately at your dealership.
CHANGE ENGINE OIL
- 82: This means that the life
of the engine oil has expired and it should be changed
within 200 miles (322 km). See ªEngine Oilº and ªFilter
Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.CHANGE TRANS FLUID

Comfort Controls
This section tells you how to make your air system work
for you.
With the ECC system, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Climate Control Panel
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 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.
Press the TEMP/AUTO knob to put the system
in the automatic mode.
Passenger's Side Temperature Button
With this dual
-zone feature, the right front passenger
can control the temperature of air for his/her own zone.
The passenger can select a four degree warmer or cooler
temperature from the driver's setting. To turn the system
on, press the PASS/TEMP button. Press the up arrow
to increase the temperature and press the down arrow to
decrease the climate setting. Pressing the OFF button
will turn off the dual
-zone function.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the SKIP INFO button (above the
radio) until ENGLISH/METRIC RESET displays. Once
displayed, press the NO INFO RESET button to select.

3-3
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off
and by vehicle speed.
Mode Button
Press the MODE button to deliver air through the floor,
middle or windshield outlets. The system will stay in the
selected mode until the MODE button is pressed again.
Press the up or down arrow to cycle through the
available modes.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will vary as the system maintains the selected
temperature setting.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 30 minutes for the system to
regulate. Turn the TEMP/AUTO knob to 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.
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 may move to the instrument
panel air outlets and floor outlets (bi
-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.

3-9

When you enter a vehicle in cold weather, adjust the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.
HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. SeeªAudio
Steering Wheel Controlsº in
the Index.
FAN SPEED: Press the up arrow lever to increase
the fan speed and the down arrow lever to decrease
fan speed.TEMP: Press the up arrow lever to increase the

This feature allows both driver's (driver 1 or 2 depending
on the number on the back of your remote keyless entry
transmitter) to personalize their own climate control
settings. For more information, see ªMemory and
Personalization Featuresº in the Index.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Setting the Clock
Press and hold HR or MN until the time display begins
to change. Release the button as you get close to the
correct time. The time may be set anytime the clock is
displayed. There is a two
-second delay before the clock
goes into time
-set mode.

4-24
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
transaxle. 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.
CAUTION:
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
transaxle, 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.

4-38 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 transaxle fluid (don't
overfill), engine oil, 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.
