2008 Mercury Mountaineer automatic transmission

Before following the procedure, make sure that:
•The parking brake is set
•The gearshift is in P (Park) (automatic transmission)
•The ignition switch is in the OFF position
•The driver and front passenger safety belts are unbuckled
While the design allows you to deactivate your Belt-Minder
, this
system is designed to improve your chances of being safely
belted and surviving an accident. We recommend you leave the
Belt-Minder
system activated for yourself and others who may use the
vehicle. To reduce the risk of injury, do not deactivate/activate the
Belt-Minder
feature while driving the vehicle.
1. Turn the ignition switch to the RUN (or ON) position. DO NOT START
THE ENGINE.
2. Wait until the safety belt warning light turns off (Approximately 1
minute).
•Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, at a moderate speed, buckle
then unbuckle the safety belt nine times, ending in the unbuckled state.
Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
•After Step 3, the safety belt warning light will be turned on for three
seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minder
feature for that seating position if it
is currently enabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds.
•This will enable the Belt-Minder
feature for that seating position if it
is currently disabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds, followed by three
seconds with the light off, then followed by the safety belt warning
light flashing four times per second for three seconds again.

Driving while you tow
When towing a trailer:
•To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1600 km) of a new vehicle.
•To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph (112
km/h) with no full throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with an automatic transmissionsection in theDriving
chapter.)
•Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
•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
•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.
•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.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.

Tires, Wheels and Loading

Vehicles with a higher center of gravity such as utility vehicles
and trucks handle differently than vehicles with a lower center
of gravity. Utility vehicles and trucks arenotdesigned for cornering at
speeds as high as passenger cars any more than low-slung sports cars
are designed to perform satisfactorily under off-road conditions. Avoid
sharp turns, excessive speed or abrupt maneuvers in these vehicles.
Failure to drive cautiously could result in an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Do not overload your vehicle
and use extra precautions, such as driving at slower speeds, avoiding
abrupt steering changes and allowing for increased stopping distance,
when driving a heavily loaded vehicle. Over-loading or loading the
vehicle improperly can deteriorate handling capability and contribute
to loss of vehicle control and vehicle rollover.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Remove the rubber pad at the
bottom of the cup holder to locate
the access cap of the floor shifter
assembly.
3. Using a screwdriver (or
equivalent), remove the access
panel and depress the shifter lever
on the shift mechanism.
4. Apply the brake and shift into N (Neutral).

Driving with a 5–speed automatic transmission (if equipped)
This vehicle is equipped with an Adaptive Transmission Control Strategy.
This Adaptive Transmission Control Strategy offers the optimal
transmission operation and shift quality. When the vehicle’s battery has
been disconnected for any type of service or repair, the transmission will
need to relearn the normal shift strategy parameters, much like having to
reset your radio stations when your vehicle battery has been
disconnected. The Adaptive Transmission Control Strategy allows the
transmission to relearn these operating parameters. This learning process
could take several transmission upshifts and downshifts; during this
learning process, slightly firmer shifts may occur. After this learning
process, normal shift feel and shift scheduling will resume.

Note:Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
JUMP STARTING
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
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.
