Mode selector control
Controls the direction of the
airflow to the inside of the vehicle.
The air conditioning compressor
will operate in all modes except
PANEL and FLOOR. However, the
air conditioning will only function
if the outside temperature is about
10ÉC (50ÉF) or above.
Since the air conditioner removes
considerable moisture from the air
during operation, it is normal if
clear water drips on the ground
under the air conditioner drain
while the system is working and
even after you have stopped the
vehicle.
Under normal conditions, your
vehicle's climate control system
should be left in any position other
than MAX A/C or OFF when the
vehicle is parked. This allows the
vehicle to ªbreatheº through the
outside air inlet duct.
²MAX A/C-Uses recirculated air
to cool the vehicle. MAX A/C is
noisier than A/C but more
economical and will cool the
inside of the vehicle faster.
Airflow will be from the
instrument panel registers. This
mode can also be used to
prevent undesirable odors from
entering the vehicle.
²A/C-Uses outside air to cool the

vehicle. It is quieter than MAX
A/C but not as economical.
Airflow will be from the
instrument panel registers.
²PANEL-Distributes outside air
through the instrument panel
registers. However, the air will
not be cooled below the outside
temperature because the air
conditioning does not operate in
this mode.
²OFF-Outside air is shut out and
the fan will not operate. For
short periods of time only, use
this mode to prevent
undesirable odors from entering
the vehicle.
²PANEL & FLOOR-Distributes
outside air through the
instrument panel registers and
the floor ducts. Heating and air
conditioning capabilities are
provided in this mode. For
added customer comfort, when
the temperature control knob is
anywhere in between the full
hot and full cold positions, the
air distributed through the floor
ducts will be slightly warmer
than the air sent to the
instrument panel registers.
²FLOOR-Allows for maximum
heating by distributing outside
air through the floor ducts.
However, the air will not be
cooled below the outside
temperature because the air
conditioning does not operate in
this mode.

²FLR & DEF-Distributes outside
air through the windshield
defroster ducts and the floor
ducts. Heating and air
conditioning capabilities are
provided in this mode. For
added customer comfort, the air
distributed through the floor
ducts will be slightly warmer
than the air sent to the
windshield defroster ducts. If
the temperature is about 10ÉC
(50ÉF) or higher, the air
conditioner will automatically
dehumidify the air to prevent
fogging.
²DEF
-Distributes outside
air through the windshield
defroster ducts. It can be used
to clear ice or fog from the
windshield. If the temperature is
about 10ÉC (50ÉF) or higher, the
air conditioner will automatically
dehumidify the air to prevent
fogging.
Operating tips
²In humid weather, select DEF
before driving. This will
prevent your windshield from
fogging. After a few minutes,
select any desired position.
²To prevent humidity buildup
inside the vehicle, don't drive
with the climate control system
in the OFF position.
²Don't put objects under the
front seat that will interfere with
the airflow to the back seats (if
equipped).

4. Insert an appropriate diameter
rod (paperclip) into the small hole
underneath the compass module
and gently press the switch for 1
to 2 seconds until ZONE and the
current zone setting is displayed
on the trip computer.
5. Release the switch, then slowly
press down again. Press the switch
repeatedly until the correct zone
setting for your geographic
location is displayed on the trip
computer.
6. To exit the zone setting mode,
release pressure from the switch
for greater than two seconds.
Compass calibration adjustment
Perform this adjustment in an
open area free from steel
structures and high voltage lines.
For optimum calibration, turn off
all electrical accessories (heater/air
conditioning, wipers, etc.) and
make sure all vehicle doors are
shut.
1. Start the vehicle.

If you ever smell exhaust
fumes of any kind inside
your vehicle, have your dealer
inspect and fix your vehicle
immediately. Do not drive if you
smell exhaust fumes. These
fumes are harmful and could kill
you.
Have the exhaust and body
ventilation systems checked
whenever:
²the vehicle is raised for service
²the sound of the exhaust system
changes
²the vehicle has been damaged in
a collision
Important ventilating
information
If the engine is idling while the
vehicle is stopped in an open area
for long periods of time, open the
windows at least 2.5 cm (one
inch).
Adjust the heating or air
conditioning (if equipped) to bring
in fresh air.
Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.

no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
When fail-safe mode is
activated
²Pull off the road as soon as
possible.
²Immediately turn the engine off
to prevent severe engine
damage.
²Wait for the engine to cool.
²Check the coolant level.
CHECKING AND ADDING
POWER STEERING FLUID
Check the power steering fluid at
least twice a year. If adding fluid is
necessary, use only MERCONt
ATF power steering fluid.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge will be near the
center of the NORMAL band).
