2003 Mercury Grand Marquis ignition

Brake system warning
•Standard instrument cluster
•Optional instrument cluster
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position (alternatively for some vehicles
when the ignition is moved from the ON position to START position, the
light will momentarily illuminate prior to reaching the START position).
It also illuminates if the parking brake is engaged. If the brake system
warning light does not illuminate as described, seek service immediately.
Illumination after the parking brake is released indicates low brake fluid
level or a brake system malfunction and the brake system should be
serviced immediately by a qualified technician. Refer toBrakesin the
Drivingchapter for more information.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has
malfunctioned and is disabled, however, the normal brake system will
still function unless the brake warning light also remains illuminated and
parking brake is off. Refer toBrakesin theDrivingchapter for more
information.

Optional instrument cluster gauges
Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the 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
ignition and let it cool. Refer toEngine coolantin theMaintenance
and specificationschapter.
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.

•Floor – Distributes outside air through the floor ducts. The air cannot
be cooled below the outside temperature.
•Mix – Distributes outside air through the floor ducts, the windshield
defroster ducts and the side window demisters. The A/C compressor
will operate automatically if the outside temperature is above
approximately 2°C (36°F). The air distributed through the floor ducts
will be slightly warmer than that sent to the windshield defroster
ducts and the side window demisters.
•
Defrost – Distributes outside air through the windshield defroster
ducts and the side window demisters. The A/C compressor will
operate automatically if the outside temperature is above
approximately 2°C (36°F). This mode will clear ice and fog from the
windshield.
Since the air conditioner removes moisture from the air, it is
considered normal operation if water drips on the ground under
the air conditioner drain.
Operating tips
•To reduce fogging under humid weather conditions, place the climate
control system in Defrost and Rear Defrost (if equipped) mode before
driving.
•To reduce humidity buildup inside the vehicle: Do not drive with the
climate control system in Off mode. Do not drive with the climate
control system in Max A/C mode (if equipped).
•Under normal weather conditions, do not leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
•Under snowy or dirty weather conditions, leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
•Remove any snow, ice or leaves from the exterior base of the
windshield.
•To increase the efficiency of the A/C (if equipped), drive with the
windows slightly open for 2–3 minutes or until the vehicle has been
“aired” out.
•Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.

To aid in side window defogging/demisting in cold weather conditions:
1. Select VENT
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer panel vents towards to side windows
To increase airflow to the outer panel vents, close the central panel
vents.
