ignition Mercury Grand Marquis 2010 s Repair Manual

a malfunction. Temporary malfunctions may cause the service engine
soon
indicator to illuminate. Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon
indicator should stay off the next time the engine is started. A driving
cycle consists of a cold engine startup followed by mixed city/highway
driving. No additional vehicle service is required.
If the service engine soon
indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon
indicator on can
result in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs.
Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the service engine soon
indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer to the On board
diagnostics (OBD-II) description in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position

TPMS reset tips:
•To reduce the chances of interference from another vehicle, TPMS
reset should be performed at least three feet (one meter) away from
another Ford Motor Company vehicle undergoing the TPMS reset
procedure at the same time.
•Do not wait more than two (2) minutes between resetting each tire
sensor or the system will timeout and the entire procedure will have
to be repeated on all four wheels.
•A double horn chirp indicates the need to repeat the procedure.
TPMS reset procedure
Note:It is recommended that you read the entire procedure before
attempting.
Note:To enter the reset mode, Steps 1–6 MUST be completed within
60 seconds.
1. Place the ignition in the off position and keep the key in the ignition.
2. Press and release the brake
pedal.
3. Cycle the ignition from off to on
three (3) times ending in the on
position—DO NOTstart the engine.

4. Press and hold the brake pedal
for two (2) seconds, then release.
5. Turn the ignition to off—DO
NOTremove the key.
6. Cycle the ignition from off to on three (3) times ending in on—DO
NOTstart the engine.
If the reset mode has been entered successfully, the horn will sound
once, and the TPMS indicator
will flash.
If after repeated attempts to enter the reset mode, the horn does not
sound, and the TPMS indicator
does not flash, seek service from
your authorized dealer.
7. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with theleft front tirein the following clockwise
order:
1. Left front tire (Front driver’s side)
2. Right front tire (Front passenger’s side)
3. Right rear tire (Rear passenger’s side)
4. Left rear tire (Rear driver’s side)

8.Left front tire:Place the TPMS reset tool against the left front tire
where the tire meets the rim, opposite from the valve stem (1) as shown.
This is where the sensor is located inside the rim.
Both tools, the TPMS training tool (part number 8C2Z-1A203-A)
or the Tire Pressure Monitor Activitation Tool (part number
204-363) must be held against the tire sidewall opposite the valve
stem as illustrated. For the TPMS training tool, the device should
be held as illustrated, with the arrow on the tool pointing
towards the rim; do not use the tool with the arrow pointing away
from the rim as it may not activate the sensor.
9. Press and release the activation button while holding either tool to the
side wall until the horn sounds. The horn will sound once within
approximately 10 seconds to indicate the process was successful.
Note:
•If a double horn chirp is heard, repeat the procedure. If a single horn
chirp is not heard, move the vehicle to rotate the wheels at least a
14-turn and repeat the procedure starting with Step 1.
•If the horn does not sound while attempting to reset any wheel, seek
service from your authorized dealer.
10. Perform Steps 8 and 9 on the right front tire, right rear tire and
finally the left rear tire. Training is complete after the horn sounds for
the last tire trained (left rear tire).
Turn the ignition to off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.

If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.
Brakes - police
The police vehicle is equipped with heavy-duty front disc brake pads to
meet the varying demands of different police service for fade resistance
and other performance requirements.
The police vehicle has standard anti-lock brakes and may be equipped
with traction control.
Brake fluid maintenance
Police pursuits involving hard braking result in very high temperatures in
the brake system, including the brake fluid. Over time, repeated
exposure to high brake temperatures can degrade brake fluid, potentially
reducing its boiling point. A lower boiling point could cause long brake
pedal travel and a loss of braking confidence during subsequent pursuit
driving. Ford recommends that police fleets replace the brake fluid at
every brake pad service interval. Brake fluid may be replaced more
frequently on vehicles involved in frequent high-speed pursuits with
heavy brake usage.
INTERIOR
Heavy-duty seats - police
The front seat assemblies, including the seat adjustment mechanisms and
supports, are ruggedly designed and ensure working comfort. An
anti-stab plate is integrated into the seat back to reduce the risk of
officer injury. An adjustable power lumbar system is standard on the
driver’s seat.
Seat belt extenders
Some police departments have begun employing the use of seat belt
extenders to make the practice of buckling and unbuckling seat belts
easier for officers wearing hip mounted radios, side arms, etc.
Seat belt extenders should never be worn when the lap strap will not
adjust snugly on the hips and/or when the intersection of the lap belt
and shoulder belt straps (measured along the lap strap) is less than six
(6) inches (15 cm) from an imaginary center line of the occupant’s body.
WARNING:Do not use extensions to change the fit of the
shoulder belt across the torso.
