Children and air bags
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.
Air bags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Front air bags are designed to inflate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.

The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags).
•Safety canopy
system (if equipped). Refer toSafety canopy

systemlater in this chapter.
•one or more impact and safing sensors.
•a readiness light and tone.
•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 wiring (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.

How does the Safety Canopysystem work?
The design and development of the
Safety Canopy
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 (including the Safety
Canopy
).
The Safety Canopy
system
consists of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of the vehicle).
•A headliner that will flex to open
above the side doors to allow Safety Canopy
deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two side crash sensors mounted at the base of the B-pillar (one on
each side).
•Two side crash sensors located at the c-pillar behind the rear doors
(one on each side).
•Roll over sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats (if equipped). The Safety Canopy
will
not interfere with children restrained using a properly installed child or
booster seat because it is designed to inflate downward from the
headliner above the doors along the side window openings.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.

spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the AdvanceTrac
stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac

operation you may experience the following:
•A rumble or grinding noise.
•A slight deceleration of the vehicle.
•The AdvanceTrac
indicator light will flash.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
system. Also, do not install a stereo
loudspeaker near the rear console or either rear seat. The
speaker vibrations can adversely affect the AdvanceTrac

sensors located in this area.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac
event
is an indication that at least some of the tires have exceeded their
ability to grip the road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To 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.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).

Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the RSS system may create false beeps.
The RSS detects obstacles up to 2
meters (6 ft.) from the rear bumper
with a decreased coverage area at
the outer corners of the bumper,
(refer to the figures for approximate
zone coverage areas). As you move
closer to the obstacle, the rate of
the tone increases. When the
obstacle is less than 25.0 cm (10
in.) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 25.0 cm (10 in.) from the side
of the vehicle, the tone will sound
for only three seconds. Once the
system detects an object
approaching, the tone will sound
again.
The RSS automatically turns on
when the gear selector is placed in
R (Reverse) and the ignition is ON.
An RSS control on the instrument
panel allows the driver to turn the
RSS on and off. To turn the RSS off,
the ignition must be ON, and the
gear selector in R (Reverse). An
indicator light on the control will
illuminate when the system is turned off. If the indicator light illuminates
when the RSS is not turned off, it may indicate a failure in the RSS.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.

CHANGING THE TIRES
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.
The use of tire sealants may damage your tires. The use of tire
sealants may also damage your tire pressure monitoring system
(if equipped).
If your vehicle is equipped with a tire pressure monitoring
system, refer toTire Pressure Monitoring System (if
equipped)in theMaintenance and specificationssection for
important information. If the tire pressure monitor sensor becomes
damaged, it will no longer function.
Dissimilar spare tire/wheel information
Failure to follow these guidelines could result in an increased
risk of tire failure, loss of vehicle control, injury or death.
Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel, then it is intended for temporary
use only. This means that if you need to use it, you should replace it as
soon as possible with a road tire/wheel that is the same size and type as
the road tires and wheels that were originally provided by Ford. If the
dissimilar spare tire or wheel is damaged, it should be replaced rather
than repaired.
When driving with the dissimilar spare tire/wheel,do not:
•Exceed 70 mph (113 km/h)
•Use more than one dissimilar spare tire/wheel at a time
•Use commercial car washing equipment
•Use snow chains on the end of the vehicle with the dissimilar spare
tire/wheel

The usage of a dissimilar spare tire/wheel can lead to impairment of the
following:
•Handling, stability and braking performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel Driving Capability (if applicable)
•Load Leveling Adjustment (if applicable)
When driving with the dissimilar spare tire/wheel additional caution
should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a dissimilar spare tire/wheel and seek
service as soon as possible.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the system indicator light will illuminate when the spare
is in use. To restore the full functionality of the monitoring system, all
road wheels equipped with tire pressure monitoring sensors must be
mounted on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by a dealer or
a qualified technician in order to prevent damage to the TPMS sensor.
Replace the spare tire with a road tire as soon as possible.
If your vehicle is equipped with AWD, a spare tire of a different
size than the road tires should not be used. Such a tire could
make the vehicle difficult to control as well as result in damage to
driveline components.

temperature. Contained air temperature is dependent upon several
factors such as rate of tire rotation, tire deflection, amount of braking,
etc. In similar manner, the tire pressure will decrease if the contained air
temperature decreases. For example, if the vehicle is stationary over
night with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease approximately 3 psi (20.7
kPa) for a drop of 30° F (16.6° C) in ambient temperature. This lower
pressure value may be detected by the TPMS as being significantly lower
than the cold pressure indicated on your vehicles tire label, and activate
the TPMS warning for low tire pressure. If the low warning light is on,
visually check each tire to verify that no tire is flat. If one or more tires
are flat, repair of fix as necessary. If all tires appear to be inflated,
carefully drive the vehicle to the nearest location where air can be added
to the tires. Turn the ignition to the “off” position. Inflate all the tires to
the recommended cold pressure.
The system uses radio-frequency to monitor the tire pressure on all tires
excluding the spare tire. The sensors transmit the tire pressure readings
to the receiver module located in the vehicle. The receiver module then
electronically transmits the status to the message center. For more tire
warning information, refer to theMessage Centerin theDriver controls
chapter.
This device complies with part 15 of the FCC rules and with RS-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, seeTire
inflation pressurein this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.

Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to the valve stem. The tire
pressure sensor must be
unbolted from the wheel prior to
tire removal. The sensor can be
removed by loosening the nut at the valve stem. Failure to
remove the sensor may damage it.The rubber grommet (washer)
between the wheel and the tire pressure sensor needs to be replaced
when any tire is changed to minimize air leaks.
The tire pressure should be checked periodically (at least monthly) using
a tire gauge, refer toTire inflation pressurein this chapter.
USING SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires or traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” tire cables. See
your dealer or qualified service technician for more information on tire
cables for your vehicle.
Follow these guidelines when using snow tires and traction devices:
•Cables or chains should only be used on the rear wheels.
•Install cables or chains securely, verifying that the cables or chains do
not touch any wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables or chains rub or bang against
the vehicle, stop and retighten them. If this does not work, remove the
cables or chains to prevent vehicle damage.
•Avoid overloading your vehicle.
•Remove the cables or chains when they are no longer needed.
•Do not use cables or chains on dry roads.
