2002 Mercury Mountaineer heating

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the
indicated area between the“H”and
“C”). If it enters the red section, the
engine is overheating. Stop the
vehicle as soon as safely possible,
switch off the engine immediately
and let the engine cool. Refer to
Engine coolantin theMaintenance and carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
Odometer
Registers the total kilometers (miles) of the vehicle.

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.
•MAX 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 restricted to instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle. When placed in MAX A/C, the A/C indicator will be
illuminated and cannot be manually disabled.
•
(Panel)-Distributes outside air through the instrument panel
registers. Heating and air conditioning capabilities are provided in this
mode. Push the A/C control in order to cool the vehicle below the
outside temperature. For added customer comfort, the system will
allow some airflow through the floor ducts in this mode.
•OFF (0)-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.
•
(Panel and floor)-Distributes outside air through the instrument
panel registers and the floor ducts. Heating and air conditioning
capabilities are provided in this mode. Push the A/C control in order
to cool the vehicle below the outside temperature. 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.
•
(Floor)-Distributes outside air through the floor ducts. Heating
and air conditioning capabilities are provided in this mode. Push the
A/C control in order to cool the vehicle below the outside
temperature.
•
(Floor and defrost)-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,
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 windshield defrost
ducts. If the outside temperature is about 6°C (43°F) or higher, the air
conditioner will automatically dehumidify the air to reduce fogging.
(Note that the A/C indicator does not illuminate when this mode is
selected.)

Auxiliary climate controls (if equipped)
Your vehicle may be equipped with auxiliary climate controls which are
located in the overhead console of the first row and in the headliner for
second row seating. The auxiliary climate control feature provides
increased capacity to quickly heat or cool your vehicle.
If your vehicle is equipped with a manual heating and air conditioning
system, the auxiliary climate controls are dependent on the main climate
control system. If the main climate control system is in the OFF position,
the auxiliary climate controls will not work.
If your vehicle is equipped with a DEATC system, the auxiliary climate
controls are independent of the main climate control system. If the main
climate control system is in the OFF position, the auxiliary climate
controls will still work. However, the A/C function will not operate unless
the A/C control has been selected on the main climate control system.
