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 seat 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 tether bracket assemblies (if equipped),
LATCH child seat tether anchors and lower anchors (if equipped), and
attaching hardware, should be inspected after a collision. Ford Motor
Company recommends that all safety belt assemblies used in vehicles
involved in a collision be replaced. However, if the collision was minor
and a qualified technician 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.
Refer toCleaning and maintaining the safety beltsin theCleaning
chapter.
AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Your vehicle is equipped with a crash sensing and diagnostic module
which records information about the air bag and sensor systems. In the

•diagnostic module.
•and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
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 toAir bag readinesssection
in theInstrument clusterchapter. Routine maintenance of the air bag 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 your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety Canopy
system (if equipped)
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.

Several Safety Canopy
system components get hot
after inflation. Do not touch them
after inflation.
If the Safety Canopysystem has deployed,the Safety
Canopywill not function again. The Safety Canopy
system (including the A, B and C pillar trim) must be inspected
and serviced by a qualified technician in accordance with the
vehicle service manual.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 theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front air bag 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 your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a collision
or rollover event.
Disposal of air bags and air bag equipped vehicles
(including pretensioners)
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.

summer grade ethanol is used in cold weather conditions, you may
experience increased cranking times, rough idle or hesitation until the
engine has warmed up. Consult your fuel distributor for the availability of
winter grade ethanol.
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
If you should experience cold weather starting problems on E
85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and carechapter for
more information on ethanol.
If the engine fails to start using the preceding instructions
1. Press the accelerator pedal 1/3 to 1/2 way to floor and hold.
2. Turn the key to START position.
3. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
4. If the engine still fails to start, repeat steps one through three.
5. After the engine starts, hold your foot on the brake pedal, put the
gearshift lever in gear and release the parking brake. Slowly release the
brake pedal and drive away in a normal manner.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23°C
(-10°F) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a“metal-to-metal,”“continuous grinding”or
“continuous squeal”sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle’s
anti-lock brake system. The ABS performs a self-check after you start
the engine and begin to drive away. A brief mechanical noise may be
heard during this test. This is normal. If a malfunction is found, the ABS
warning light will come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.

Each day before 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 every few weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor overloaded.
Periodically inspect the tire treads and remove stones, nails, glass or
other objects that may be wedged in the tread grooves. Check for holes
or cuts that may permit 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 reliable and reasonably predictable
performance whether loaded or empty and durable load carrying
capability. For this reason, Ford Motor Company strongly recommends
that you do not make modifications such as adding or removing parts
(such as lift kits or stabilizer bars) or by using replacement parts not
equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.
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 800 km
(500 miles).
•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. Remember to figure in the tongue
load of your loaded vehicle when figuring the total weight.
Note:Do not exceed the GVWR or the GAWR specified on the
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
control, and personal injury.

Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Never connect any trailer lighting to the vehicle’s taillamp
circuits, because it may damage the electrical system resulting in
fire. Contact your local Ford dealership for assistance in proper trailer
tow wiring installation. Additional electrical equipment may be
required.
Driving while you tow
When towing a trailer:
•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 a 4–speed automatic transmissionsection in this
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 your scheduled maintenance guide for
more information.

Power distribution box
The power distribution box is
located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle’s main electrical systems
from overloads.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, always replace the cover to
the Power Distribution Box before reconnecting the battery or
refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and specificationschapter.

CHANGING THE TIRES
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.
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 to Tire Pressure Monitoring System (if equipped)
in theMaintenance and caresection 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. The spare is
identical to the other tires on your vehicle, although the wheel will not
match.
If your vehicle is equipped with AWD, 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 injury or death.
