AUXILIARY POWER POINT (12VDC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
The auxiliary power point is located under the cup holder and ashtray
drawer in the center stack. The auxiliary power point for five passenger
vehicles is located in the floor console storage bin.
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer to
Fuses and
relays
in the
Roadside Emergencies
chapter for information on
checking and replacing fuses.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.

Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
Ford Motor Company recommends that an authorized dealer
inspect all steering column assemblies in use in vehicles involved
in a collision. Failure to inspect and if necessary replace the steering
column assembly could result in severe injury or death in the event of
a collision.
Do not attempt to service, repair, or modify the steering column,
its adaptive module, or its fuses. See your authorized dealer.
To properly position yourself away from the airbag:
Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your authorized
dealer.
The front passenger airbag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.

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.
Do not attempt to service, repair, or modify the airbag SRS, its
fuses or the seat cover on a seat containing an airbag. See your
authorized dealer.
All occupants of the vehicle should always wear their safety belts
even when an airbag SRS is provided.
How does the side airbag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
The side airbag system consists of
the following:
An inflatable nylon bag (airbag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
A special seat cover designed to allow airbag deployment.
The same warning light, electronic control and diagnostic unit as used
for the front airbags.
Two crash sensors located near the side of the vehicle.
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.

the customer has disabled the system using the traction control switch
located on the left side of the instrument panel.
The Traction Control™ system will be on every time you turn the
ignition key from OFF to ON until you deactivate the system using the
traction control switch on the instrument panel left of the steering
column.
STEERING
Ford Motor Company recommends that an authorized dealer
inspect all steering column assemblies in use in vehicles involved
in a collision. Failure to inspect and if necessary replace the steering
column assembly could result in severe injury or death in the event of
a collision.
Do not attempt to service, repair, or modify the steering column,
its adaptive module, or its fuses. See your authorized dealer.
To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running.
It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:

TRACTION-LOK™ AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok™ axle functions like a standard rear axle.
Extended use of other than the manufacturer’s specified size tires on a
Traction-Lok™ rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock – column-shift transmission
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, it is possible that a fuse
has blown or the vehicle’s brakelamps are not operating properly. Refer
to
Fuses and relays
in the
Roadside Emergencies
chapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to 2 (ACC).
2. Locate the access plug on the
underside of the steering column
cover.
3. Remove the access plug using a flat head screwdriver. Insert the
screwdriver into the access hole nearest the steering wheel. Then push
and hold the override button using a flat head screwdriver. Apply the
brake pedal and shift the transmission into N (Neutral) while continuing
to depress the override button.
4. Reinstall the access plug cover, start the vehicle and release the
parking brake.

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

CHANGING A FLAT TIRE
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.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.
Note:
The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer to
Tire Pressure Monitoring System
(TPMS)
in the
Tires, Wheels, and Loading
chapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.
