Air recirculation button
(if so equipped)
NOTE:
The air recirculation feature is available
only on those vehicles equipped with air
conditioning.
OFF position (indicator light OFF):
Outside air is drawn into the passenger
compartment and distributed through the
selected outlets.
Use the OFF position for normal heater or
air conditioner operation.
ON position (indicator light ON):
Interior air is recirculated inside the vehicle.
Depress the air recirculation button to acti-
vate the recirculation function when driving
on a dusty road or to avoid traffic fumes.
The air recirculation function is also used to
improve A/C performance during extremely
hot or humid conditions.
Air conditioner button
(if so equipped)
Start the engine, move the fan control dial to
the desired (one to four) position, and push
the air conditioner button to turn on the air
conditioner. The indicator light comes on
when the air conditioner is on. To turn off the
air conditioner, push the button again.
The air conditioner cooling function op-
erates only when the engine is running.
HEATER OPERATION
Heating
This mode is used to direct hot air mainly
from the floor outlets. A small amount of air
also flows from the defrost outlets.
1. Push the air recirculation button (if so
equipped) to the OFF position for normal
heating.
2. Move the air control dial to the
po-
sition.
3. Move the fan control dial to the desired
position.
4. Move the temperature control dial to thedesired position between the middle and
the hot position.
Ventilation
This mode directs outside air from the side
and center vents.
1. Push the air recirculation button (if so
equipped) to the OFF position.
2. Move the air control dial to the
po-
sition.
3. Move the fan control dial to the desired
position.
4. Move the temperature control dial to the
desired position.
Defrosting or defogging
This mode is used to defrost/defog the
windows.
1. Move the air control dial to the
po-
sition.
cWhen the
position is selected the
(air recalculation) function auto-
matically cancels. Outside air is drawn
into the passenger compartment to im-
prove the defogging performance.

For quick cooling when the outside tem-
perature is high, push the air recirculation
button to the ON position. Be sure to return
the air recirculation button to the OFF posi-
tion for normal cooling.
Dehumidified heating
This mode is used to heat and dehumidify
the air.
1. Push the air recirculation button to the
OFF position.
2. Move the air control dial to the
po-
sition.
3. Move the fan control dial to the desired
position.
4. Push on the air conditioner button. The
indicator light comes on.
5. Move the temperature control dial to the
desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidify the air.
1. Move the air control dial to the
po-
sition.
cWhen the
position is selected the
(air recalculation) function auto-
matically cancels. Outside air is drawn
into the passenger compartment to im-
prove the defogging performance.
2. Move the fan control dial to the desired
position.
3. Push on the air conditioner button. The
indicator light comes on.
4. Move the temperature control dial to the
desired position.
Operating tips
cKeep windows and sunroof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperaturegauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See ``If your
vehicle overheats'' in the ``In case of
emergency'' section of this manual.

cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
c
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with an automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P position.
If you move the shift selector lever to the P
position before blocking the wheels andapplying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature coolant rises
to an extremely high temperature when
the air conditioning system is on, turn off
the air conditioner. Coolant heat can be
additionally vented by opening the win-
dows, switching the fan control to high
and setting the temperature control to
the HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently. For
additional information see the ``Mainte-
nance'' section earlier in this manual.
