2000 Mercury Grand Marquis cooling

²Optional instrument cluster
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. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and care chapter.
Battery voltage gauge (if equipped)
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated), have the vehicle's
electrical system checked as soon as
possible.
Engine oil pressure gauge (if equipped)
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªHº and ªLº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.

²To prevent humidity buildup inside the vehicle, do not drive with the
climate control system in the OFF or MAX A/C position.
²Do not put objects under the front seat that will interfere with the
airflow to the back seats.
²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate your air
conditioner as you would normally.
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Also, avoid placing small objects on top of your instrument panel.
These objects can fall down into the defroster outlets and block
airflow and possibly damage your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
Electronic Automatic Temperature Control (EATC) system
(if equipped)
The EATC system will maintain a
selected temperature and
automatically control airflow. You
can override automatic operation
with any of the override controls or
the fan speed control.

To control the temperature, select
any temperature between 18ÉC
(65ÉF) and 29ÉC (85ÉF) by pressing
the blue (cooler) or red (warmer)
buttons.
For continuous maximum cooling, push the blue button until 16ÉC
(60ÉF) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the red button.
For continuous maximum heating, push the red button until 32ÉC (90ÉF)
is shown in the display window. The EATC will continue maximum
heating (disregarding the displayed temperature) until a cooler
temperature is selected by pressing the blue button.

switch between Fahrenheit and

If your vehicle has an English/Metric (E/M) control to change your
electronic instrument cluster display (if equipped) and the message
center display (if equipped) from English to Metric, this control will also
change the temperature display. Refer toElectronic Message Centerin

Driving while you tow
When towing a trailer:
²Ensure that you turn off your speed control. The speed control may
shut off automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
²Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10% of the loaded trailer weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Temporary spare tire information
Your vehicle may have a temporary or full-size spare tire. The temporary
spare tire for your vehicle is labeled as such. It is smaller than a regular
tire and is designed for emergency use only. Replace this tire with a
full-size tire as soon as possible.
If you use the temporary spare tire continuously or do not follow
these precautions, the tire could fail, causing you to lose control
of the vehicle, possibly injuring yourself or others.

Do not attempt to push start your vehicle. Automatic
transmissions do not have push-start capability.
Preparing your vehicle
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.

WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Only use a washer fluid that meets Ford specifications. Refer to
Lubricant specificationsin theCapacities and specificationschapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle's paint finish, wiper blades or washer system.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
ENGINE COOLANT
Checking engine coolant
Your engine's cooling system has been factory-filled with a 50/50 mixture
of distilled water and Ford Premium Engine Coolant E2FZ-19549-AA (in
Canada, Motorcraft CXC-10), or an equivalent premium engine coolant
that meets Ford specification ESE-M97B44-A.
A50/50 mixtureof distilled water and Ford Premium Engine Coolant
provides:
²maximum cooling system efficiency.
²freeze protection down to -36É C (-34É F).
²boiling protection up to 129É C (265É F).
