starter Mercury Grand Marquis 2004 Owner's Manuals

Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
1. Turn the key to 4 (ON) without
turning the key to 5 (START).
2. Turn the key to 5 (START), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -10°F (-23°C) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.

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.
