If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steadypattern. Press lightlyon the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fullyreleased, but the brake warning lamp
remains illuminated, the brakes maynot be working properly.
See your dealer or a qualified service technician.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
Emergency maneuvers
•In an unavoidable emergencysituation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel onlyas rapidlyand as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergencystop, avoid skidding the tires and do not
attempt anysharp steering wheel movements.

sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, tryto keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadilythrough the terrain. Applythe accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capabilitymaybe limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle maystall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectivelyas drybrakes. Drying can be improved bymoving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, applythe accelerator slowlyand avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.

Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originallyprovided byFord Motor Companybecause it can affect
the safetyand performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover, and/or serious
personal injuryor death.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand and load-carrying capacity. If you have questions
regarding tire replacement, see an authorized Ford or Lincoln/Mercury
dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford Motor Companyrecommends, you should not use
these tires for highwaydriving.
If you use anytire/wheel combination not recommended byFord Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure.
Do not use “aftermarket lift kits” or other suspension modifications,
whether or not theyare used with larger tires and wheels.
These “aftermarket lift kits” could adverselyaffect the vehicle’s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highwaydriving because theyare more
likelyto blow out or fail.
You should carefullyobserve the recommended tire inflation pressure
found on the safetycompliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adverselyaffect the wayyour vehicle
handles. Do not exceed the Ford Motor Companyrecommended pressure
even if it is less than the maximum pressure allowed for the tire.
Driving

Each daybefore you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires, and adjust if
required. Check tire pressure with a
tire gauge everyfew weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodicallyinspect the tire treads and remove stones, nails, glass or
other objects that maybe wedged in the tread grooves. Check for holes
or cuts that maypermit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
in case it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide both reasonablysafe, predictable performance
whether loaded or emptyand durable load carrying capability. For this
reason, Ford Motor Companystronglyrecommends that you do not make
modifications such as adding or removing parts (such as lift kits or
stabilizer bars) or byusing replacement parts not equivalent to the
original factoryequipment.
Anymodifications to a vehicle that raise the center of gravitycan make
it more likelythe vehicle will roll over as a result of a loss of control.
Ford Motor Companyrecommends that caution be used with anyvehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properlymayvoid the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adverselyaffect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavyoff-road usage.
POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some vehicles maybe equipped with Power Take Off (PTO) capability.
These vehicles have a special transmission case, internal components and
calibration for PTO usage.

Book. These instructions are available through your Ford dealer; they
include the list of vehicle models recommended for snowplowing and
snowplow weight limits. Use of the Snowplow Package Option, or its
equivalent, along with these instructions will help avoid possible
powertrain and chassis damage from snowplowing.
The front and rear GAWR, GVWR, Total AccessoryReserve Capacity
(TARC) and tire inflation pressures are found on the SafetyCompliance
Certification Label located on one of the vehicle’s door jambs. This label
is applied to all vehicles completed byFord Motor Company. Incomplete
vehicles built byFord Motor Companywill have an Incomplete Vehicle
Label in place of the SafetyCompliance Label. The TARC does not apply
to Incomplete Vehicles and will not be shown on the Incomplete Vehicle
Label. The weight of the vehicle with occupants must never exceed the
front and rear GAWR or the GVWR.
The TARC is the weight of the permanentlyattached equipment that can
be added to the vehicle without violating the vehicle’s SafetyCompliance
Certification. This includes the snowplow mounting hardware but does
not include the removable portion of the snowplow assembly.
Installing the snowplow
Read the following instructions before installing a snowplow:
•Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find your vehicle’s front GAWR.
•
The Front Axle AccessoryReserve Capacityand the TARC listed on the
bottom right of the SafetyCompliance Certification Label will determine
whether or not the addition of a snowplow will overload your vehicle.
•The weight of the snowplow and supporting components distributed to
the front axle must not exceed the Front Axle AccessoryReserve
Capacity.
•The total weight of the snowplow and aftermarket equipment must
not exceed the TARC.
•The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the SafetyCompliance Certification Label.
•The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the GCWR for
towing.
•Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.

•Tires have their maximum inflation pressure and associated load rating
imprinted on the tire sidewall. This pressure mayor maynot be the
same as that shown as recommended on the vehicle. The vehicle
operator mayhave to adjust the tire inflation pressure to
accommodate the snowplow and payload. Consult your dealer or
equipment installer for help with proper inflation pressures.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•After installing a snowplow to the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle’s Workshop
Manual.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Removing snowplow
After removing a snowplow from the vehicle, ensure the vehicle’s front toe
alignment and front ride height are within specification (reset if required).
Snowplowing with your air bag-equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploythe air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properlywear their safetybelts, even when an air bag (SRS) is
provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment byits manufacturer. Doing so maycause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modifythe Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercurydealer.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•graduallydecrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowlymove to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrityof your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
Spare tire information
Your vehicle maybe equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire maybe used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injuryor death.
If your vehicle is equipped with a tire pressure monitoring
system, refer to Tire Pressure Monitoring System (if equipped)
in the Maintenance and specifications section for important information
before changing your tires. If the tire pressure monitoring system
becomes damaged, it will no longer function.

14. Insert the jack handle into the
pump linkage.
15. Use an up-and-down motion
with the jack handle to raise the
wheel completelyoff the ground.
Hydraulicjacks are equipped
with a pressure release valve
that prevents lifting loads which
exceed the jack’s rated capacity.
16. Remove the lug nuts with the lug wrench.
17. Replace the flat tire with the spare tire, making sure the valve stem
is facing outward on all front an inboard rear wheels. If replacing the
outboard wheel, the valve stem must be facing inward. Reinstall the lug
nuts until the wheel is snug against the hub. Do not fullytighten the lug
nuts until the wheel has been lowered.
18. Lower the wheel byslowlyturning the release valve
counterclockwise. Opening the release valve slowlywill provide a more
controlled rate of descent.

2. Slide the wheel partiallyunder the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
3. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantlyand the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your dealer for
assistance at your earliest convenience.
4. Check that the tire lies flat against the frame and is properly
tightened. Tryto push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire mayresult in failure of the winch cable and loss of the tire.
5. Repeat this tightness check procedure when servicing the spare tire
pressure (everysix months, per scheduled maintenance guide), or at any
time that the spare tire is disturbed through service of other
components.
6. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key(if equipped) and jack handle.
JUMP STARTING YOUR VEHICLE
The gases around the batterycan explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injuryor
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
Preparing your vehicle
When the batteryis disconnected or a new batteryis installed, the
transmission must relearn its shift strategy. As a result, the transmission
mayhave firm and/or soft shifts. This operation is considered normal and
will not affect function or durabilityof the transmission. Over time, the
adaptive learning process will fullyupdate transmission operation.

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clearcoat paint
finish. In order to maintain their shine:
•Clean weeklywith Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation mayrequire agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never applyanycleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes maycause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear awaythe clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when theyare clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spraya hot engine with cold water to avoid cracking the
engine block or other engine components.
•SprayMotorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.
