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 out
of range will also cause the transmitter not to work.
If only the instant alarm works, the transmitter needs
to be resynchronized to the receiver. Resynchronize by
pressing and holding both the buttons with the lock
and unlock symbols at the same time for about eight
seconds. You must be within range of the vehicle.
Once the transmitter has been resynchronized, the locks
will cycle (the horn may chirp and the exterior lamps
may flash) depending on the security feedback settings.
The system should now operate 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 any airflow selection except RECIRC.
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.

2-49 Rear Reading Lamps
These lamps will come on when you open the doors.
You can also turn them on by pressing the button on the
side of the lamp. Press it again to turn them off.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's
battery against drainage from the interior lamps,
trunk lamp, glove box lamp or cigarette lighters.
When the ignition is turned off, the power to these
features will automatically turn off after 10 minutes.Power will be restored for an additional 10 minutes if
any door is opened, the trunk is opened or the courtesy
lamp switch is turned on. To restore power back to
the cigarette lighters the ignition must be turned back
to RUN.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the battery
charges. High electrical loads may occur when several
of the following are on: headlamps, high beams, fog
lamps, rear window defogger, high blower fan, heated
seats and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the blower fan,
rear defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.

RECIRC: Press this button to limit the amount
of outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly
or limit the amount of outside air entering your vehicle
for some other reason. The RECIRC button and the
AUTO
-PUSH knob may be selected at the same time.
The system will remain in RECIRC until the ignition
is turned off, then the system will return back to the
previously selected mode. RECIRC may be selected
in all manual airflow modes except front defrost.
When the weather is cool or damp, operating in
RECIRC for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
switch back to outside air by turning off RECIRC,
select either DEFOG or front defrost mode and increase
the fan speed. To avoid refogging of the windows,
minimize your use of RECIRC under these conditions
and turn the A/C on to help dehumidify the air.
A/C: Press this button to turn the air conditioning
compressor on and off. If the system is operating in
the automatic mode, the A/C indicator light will
automatically illuminate. In the auto mode, the
A/C compressor will only operate when the system
determines it is needed.OFF: Turn the AUTO
-PUSH knob to OFF. Turning
the system off will cause the fan to turn off and the
airflow to be directed out the lower floor outlets. The
system will still try to keep the interior of the vehicle
at the previously chosen comfort setting. The outside
temperature will show in the display when the system
is set to OFF.
Air Conditioning
The air conditioner cools and dehumidifies the air for
the inside of the vehicle.
The air conditioning compressor is enabled in all
modes unless the A/C button is in the off position
(the indicator light will not be illuminated). However,
the air conditioning compressor will not operate when
the outside temperature is below 34
F (1
C). 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 cooling
and help fuel economy.

3-7
On very hot days, open the windows long enough to
let the hot air out. This reduces the time required to
cool the interior of the vehicle to a comfortable level.
If the system is in the automatic mode (AUTO
-PUSH
knob indicator light is on), during very hot days the
system will automatically go to the RECIRC mode and
the temperature door will initially be at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
F (16
C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will initially be
positioned at the full hot position. You can choose the
extreme comfort setting of 90
F (32
C), but the
system will not warm up any faster by selecting the
extreme comfort setting.In cold weather, the system will delay turning on the
fan to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature of the engine coolant increases. Turning the
AUTO FAN knob will override this delay by turning
off the automatic fan control mode and changing the
fan speed.
Defogging and Defrosting
On cool, humid days, use the defog setting to keep
the windows clear while also providing heat through the
lower outlets. Turn the AUTO
-PUSH knob clockwise to
DEF to quickly remove fog or ice from the windshield.
For maximum front defrost performance under extreme
icing or frosting conditions, increase the temperature
setting to 90
F (33
C) and increase the fan speed
to high.

3-10 Steering Wheel Controls for Climate Control
Some heating and cooling
controls can be adjusted
at the steering wheel.
Other touch controls
also operate some audio
controls. See ªAudio
Steering Wheel Controlsº
later in this section.
Press the upper part of the fan symbol button to override
the automatic fan control and increase the fan speed.
Press the lower part of the fan symbol button to override
the automatic fan control and reduce the fan speed.
Press either arrow on the TEMP button once to display
your current comfort setting in the digital display. Press
the upper part of the TEMP button again to provide a
warmer comfort setting or press the lower part of the
TEMP button again to provide a cooler comfort setting.
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 until the correct hour appears. The
letters AM or PM will appear on the display. Then, press
and hold MN until the correct minute appears. The clock
may be set with the ignition on or off. In addition, the
clock can also be automatically set, when tuned to an
RDS station that is broadcasting time, by pressing and
holding the HR and the MN button at the same time.
The display will show TIME UPDATED. If there is no
time available, NO UPDATE will be displayed.

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. Drive in the highest
gear possible.

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.

4-37
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet.
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 apply your parking
brake, and then shift to PARK (P).
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

Release the parking brake.
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 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.
Each of these is covered in this manual, and the Index
will help you find them quickly. 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. Two Electric Engine Cooling 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.
