•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 air bag supplemental restraint systems
or its fuses. See your Ford or Lincoln Mercury
dealer.
Modifications to the front end of the vehicle,
including frame, bumper, front end body
structure and tow hooks may affect the
performance of the air bag sensors increasing the
risk of injury. Do not modify the front end of the
vehicle.
Children and air bags
For additional
important safety
information, read all
information on safety
restraints in this guide.
Children must always
be properly restrained.
Accident statistics
suggest that children
are safer when
properly restrained in
the rear seating
positions than in the front seating position. Failure
to follow these instructions may increase the risk of
injury in a collision.

3. Start the vehicle.
If it is necessary to use the above procedure to
move the gearshift lever, it is possible that a fuse
has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin the
Roadside emergencieschapter.
Do not drive your vehicle until you verify
that the brakelamps are working.
If your vehicle gets stuck in mud or snow it may be
rocked out by shifting from forward and reverse
gears, stopping between shifts, in a steady pattern.
Press lightly on 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 fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.

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 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).
Temporary spare tire information
Your vehicle may have a temporary spare tire. The
temporary spare tire for your vehicle is labeled as
such. It is smaller than a regular tire and is designed
for emergency use only. Replace this tire with a
full-size tire as soon as possible.
