•The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights.
How does the Restraint Safety System work?
The Restraint Safety System can adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the restraints control module. During a crash, the
restraints control module may activate the safety belt pretensioners
and/or either one or both stages of the dual-stage airbag supplemental
restraints based on crash severity and occupant conditions.
SOS POST-CRASH ALERT SYSTEM™
The system flashes the turn signal lamps and sounds the horn
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle, such as front, side, side curtain or Safety
Canopy.
The horn and lamps will turn off when:
•the hazard control button is pressed
•the panic button (if equipped) is pressed on the remote entry
transmitter, or
•your vehicle runs out of power.
DRIVER AND PASSENGER AIRBAGS
WARNING:Never place your arm or any objects over an airbag
module. Placing your arm over a deploying airbag can result in
serious arm fractures or other injuries. Objects placed on or over the
airbag inflation area may cause those objects to be propelled by the
airbag into your face and torso causing serious injury.
WARNING:Airbags can kill or injure a child in a child seat.
Never place a rear-facing child seat in front of an active airbag. If
you must use a forward-facing child seat in the front seat, move the
seat all the way back.

STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the 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:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components

Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your tire pressure monitoring system.
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged.
Safety Practices
WARNING:If your vehicle is stuck in snow, mud, sand, etc., do
not rapidly 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.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits.
•Avoid fast starts, stops and turns.
•Avoid potholes and objects on the road.
•Do not run over curbs or hit the tire against a curb when parking.
Highway Hazards
No matter how carefully you drive, there is 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 the 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.
