CHANGING THE TIRES
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrity of your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
If your vehicle is equipped with a tire pressure monitoring
system, refer toTire Pressure Monitoring System (if
equipped)in theMaintenance and specificationssection for
important information. If the tire pressure monitor sensor becomes
damaged, it will no longer function.
Spare tire information
The spare tire can be used as a spare or a regular tire and is identical to
the other tires on your vehicle.
If your vehicle is equipped with AWD, a spare tire of a different
size than the road tires should not be used. Such a tire could
make the vehicle difficult to control as well as result in damage to
driveline components.

Stopping and securing the vehicle
1. If you get a flat tire while driving,
do not apply the brake heavily;
instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.
2. Park on a level surface, activate
the hazard flashers and set the
parking brake.
3. Place gearshift lever in P (Park)
and turn engine OFF.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park).
Note:Passengers should not remain
in the vehicle when the vehicle is
being jacked.
4. Block the wheel that is diagonally
opposite of the flat tire using the
wheel chock provided with your
vehicle.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just in front of the
rear bumper. The spare tire winch drive
nut is located at the rear center of the
cargo area under a lid.
Jack, lug nut wrench, jack
handle, wheel chockBehind the rear seat under the carpeted
floor lid in the cargo floor. The tools are
located in a bag attached to the jack.

2. Insert the lug wrench on the
winch drive nut.
The wrench will stop moving and
forward resistance to turning will be
felt when properly engaged.
3. Turn the wrench
counterclockwise until the tire is
lowered to the ground and the cable
has slack. When turning the wrench,
make sure that it does not scuff the
kick plate.
4. Slide the tire rearward, lift one
side and remove the retainer from
the spare tire.
Changing the spare tire
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block the wheel that is
diagonally opposite (other end of the vehicle) to the tire being
changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

JUMP STARTING YOUR VEHICLE
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 vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
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.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.

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 weekly with Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause 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 away the 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 they are 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 spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
