After any vehicle collision, the combination lap and shoulder belt
system at all passenger seating positions must be checked by an
authorized dealer to verify that the “automatic locking retractor”
feature for child seats is still functioning properly, in addition to other
checks for proper safety belt system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly “automatic locking retractor” feature or
any other safety belt function is not operating properly. In addition, all
safety belts should be checked for proper function. Failure to replace
the belt and retractor assembly could increase the risk of injury in
collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner tightens the safety belts firmly against the
occupant’s body at the start of the crash.
When the optional Safety Canopysystem, seat-mounted side airbags,
and/or the front airbags are activated, the safety belt pretensioners for
the driver and right front passenger seating positions will be activated
when the respective seatbelt is properly buckled.
The driver and front passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the
vehicle is involved in a collision that results in deployment of front
airbags, seat-mounted side airbags and Safety Canopy(if equipped),
and safety belt pretensioners.
Refer to theSafety belt maintenancesection in this chapter.

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 9 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 restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within approximately 7 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 restraint system warning
light will flash 4 times per second for 3 seconds.
•This will enable the Belt-Minder
feature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash 4 times per second for 3 seconds, followed by 3
seconds with the light off, then followed by the restraint system
warning light flashing 4 times per second for 3 seconds again.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front safety belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat LATCH and tether anchors, and attaching
hardware, should be inspected after a collision. Ford Motor Company
recommends that all safety belt assemblies in use in vehicles involved in
a collision be replaced. However, if the collision was minor and an
authorized dealer finds that the belts do not show damage and continue
to operate properly, they do not need to be replaced. Safety belt
assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.

Any alteration/modification to the front passenger seat may
affect the performance of the front passenger sensing system.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAirbag readinesssection
in theInstrument Clusterchapter. Routine maintenance of the airbag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Seat-mounted side airbag system
Do not place objects or mount equipment on or near the airbag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying airbag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side airbags and
increase the risk of injury in an accident.
Do not lean your head on the door. The side airbag could injure
you as it deploys from the side of the seatback.

If the Safety Canopy
system has deployed,the
Safety Canopywill not
function again. The Safety
Canopysystem (including the
A, B and C pillar trim) must be
inspected and serviced by an
authorized dealer.If the Safety
Canopyis not replaced, the
unrepaired area will increase the
risk of injury in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness light (same light as for front airbag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision or rollover event.
Disposal of airbags and airbag equipped vehicles
(including pretensioners)
See your authorized dealer. Airbags MUST BE disposed of by qualified
personnel.

Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in theDrivingchapter. Information on transfer case
maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
Do not become overconfident in the ability of 4WD and AWD
vehicles. Although a 4WD or AWD vehicle may accelerate better
than two-wheel drive vehicle in low traction situations, it won’t stop
any faster than two-wheel drive vehicles. Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
•Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs than a vehicle with a longer
wheelbase.

cracking, cuts, bruises and other signs of damage or excessive wear. If
internal damage to the tire is suspected, have the tire demounted and
inspected in case it needs to be repaired or replaced. For your safety,
tires that are damaged or show signs of excessive wear should not be
used because they are more likely to blow out or fail.
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire wear
When the tread is worn down to
1/16th of an inch (2 mm), tires must
be replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or “wear bars”, which
look like narrow strips of smooth
rubber across the tread will appear
on the tire when the tread is worn
down to 1/16th of an inch (2 mm).
When the tire tread wears down to
the same height as these “wear bars”, the tire is worn out and must be
replaced.
Damage
Periodically inspect the tire treads and sidewalls for damage (such as
bulges in the tread or sidewalls, cracks in the tread groove and
separation in the tread or sidewall). If damage is observed or suspected
have the tire inspected by a tire professional. Tires can be damaged
during off-road use, so inspection after off-road use is also
recommended.
Age
Tires degrade over time depending on many factors such as
weather, storage conditions, and conditions of use (load, speed,
inflation pressure, etc.) the tires experience throughout their lives.
In general, tires should be replaced after six years regardless of tread
wear. However, heat caused by hot climates or frequent high loading
conditions can accelerate the aging process and may require tires to be
replaced more frequently.
You should replace your spare tire when you replace the road tires or
after six years due to aging even if it has not been used.

If your vehicle is stuck in snow, mud, sand, etc.,do notrapidly
spin the tires; spinning the tires can tear the tire and cause an
explosion. A tire can explode in as little as three to five seconds.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front wheel drive (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance informationthat comes with your vehicle) will
help your tires wear more evenly, providing better tire performance and
longer tire life. Unless otherwise specified, rotate the tires approximately
every 5,000 miles (8,000 km).

TIRE PRESSURE MONITORING SYSTEM (TPMS)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
The Tire Pressure Monitoring System is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, see
Inflating your tiresin this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.

TRAILER TOWING
Trailer towing with your vehicle may require the use of a trailer tow
option package.
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing procedure:
•Stay within your vehicle’s load limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
•Do not tow a trailer until your vehicle has been driven at least
500 miles (800 km).
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter when figuring the total weight of your
vehicle.
Your vehicle is equipped with a standard Class II integrated hitch and
requires only a draw bar and ball with a 19 mm (3/4 inch) shank
diameter. An optional Class III/Class IV hitch is also available.
Note:Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.

Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make 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.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
