2010 Mercury Grand Marquis service interval

•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer toAutomatic
transmission operationin theDrivingchapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•Practice turning, stopping and backing-up 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.
•Allow more distance for stopping with a trailer attached.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the FULL COLD level or within the
COLD FILL RANGE as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.

4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer toMaintenance
product specifications and capacitiesin this chapter for the proper
fluid type.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the MAX line that
do not trigger the brake system
warning lamp are within the normal
operating range, there is no need to
add fluid. If the fluid levels are outside of the normal operating range,
the performance of your brake system could be compromised, seek
service from your authorized dealer immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, i.e., if the transmission slips or
shifts slowly or if you notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about
30 minutes to allow fluid to cool before checking.

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.

ELECTRICAL
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

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.
