service indicator Mercury Grand Marquis 2010 s User Guide

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

for 15 seconds without cranking the engine. If the service engine
soon
indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if the service engine soon
indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
POWER STEERING FLUID
Check the power steering fluid.
Refer toscheduled maintenance
information.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.

Example:When the odometer has accumulated 3,000 miles (4,828 km)
and the idle meter shows 61 hours, a 5,000 mile (8047 km) oil change
interval will have been reached: 3,000 road miles + (61 idle hours x
33 miles/idle hour) = 5,013 miles. In metric units this calculation would
be 4,828 kilometers + (61 idle hours x 53 km/idle hour) = 8,061 km.
REAR AXLE
Axle break-in – Police and middle eastern countries only
Rear axles in vehicles destined for use by police or in middle eastern
countries are equipped with a synthetic lubricant. Do not drive over
100 mph (160 km/h) for the first 1,000 miles (1,600 km) to allow axle
components to wear in. Additionally, only synthetic lubricant as specified
below should be used when maintenance is performed on the rear axle.

Battery - police
The Motorcraft
maintenance-free battery normally does not require
additional water during its life. However, for severe service usage or in
high temperature climates, the electrolyte level should be checked at
least every five months or 5,000 miles (8,000 km). If the electrolyte level
is below the level indicator in any cell, add enough pure water to bring
the level up to the indicator. Never add electrolyte (battery acid) to the
battery as this could shorten battery life.
Battery - long term storage
Make sure that the battery is fully charged before putting the vehicle in
storage. Disconnect the negative cable if it will be stored for an extended
period of time.
If the battery is discharged, allow it to warm to a moderate temperature,
such as 60°F (16°C), and use a battery charger rather than the vehicles
charging system to bring the battery back to full charge. Use a battery

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)
