Knee airbag system (driver’s side only)
The knee airbag is located under the instrument panel. The system
works along with the driver’s front airbag to help reduce injury to the
legs. When the driver’s airbag activates in a collision, the knee airbag
deploys from under the instrument panel.
As with front and side airbags, it is important to be properly seated and
restrained to reduce the risk of death or serious injury.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions,

WARNING:Do not attempt to service, repair, or modify the
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. Contact your authorized dealer as soon as possible.
WARNING: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 bag (airbag) with an
inflator 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.
•Crash sensors located on the
front doors and C pillars (one
sensor on each pillar on each 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 side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.

How does the side air curtain system work?
The design and development of the
side air curtain 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 side air
curtain systems).
The side air curtain system consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner and above the doors.
•The headliner will flex to open
above the side doors to allow air
curtain deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two pressure sensors located in the front doors.
•Two crash sensors located on the rocker panel between the “C” pillar.
Side air curtains and side airbags, in combination with safety belts, can
help reduce the risk of severe injuries in the event of a significant side
impact collision.
Children 12 years old and under should always be properly restrained in
the rear seats. The side air curtain 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 side air curtains are mounted to the sheet metal above the first and
second row seats. In certain lateral collisions, the air curtain and
seat-mounted side airbag on the side affected by the collision will be
inflated, except that the passenger sensing system will deactivate the
passenger seat-mounted side airbag if it detects an empty unbuckled
passenger seat. The air curtain was designed to inflate between the side
window area and occupant to further enhance the head protection

provided to occupants in side impact collisions. The seat-mounted side
airbag was designed to inflate between the door panel and occupant to
further enhance the protection provided occupants in side impact
collisions.
The side air curtain system SRS is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the sensors to close an
electrical circuit that initiates air curtain and seat-mounted side airbag
inflation.
The fact that the side air curtain and seat-mounted side airbag 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. The side air curtain system is designed to inflate in side
impact collisions, not roll-over, rear impact, frontal or near-frontal
collisions, unless the collision causes sufficient lateral deceleration.
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING:If the side air
curtain has deployed,the
air curtain will not function
again. The side air curtain
system (including the A, B and
C pillar trim and headliner)
must be inspected and serviced
by an authorized dealer.If the
air curtain is 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 toWarning lights and
chimesin theInstrument Clusterchapter. Routine maintenance of the
side airbag 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 airbag system) will either
flash or stay lit.

WARNING:When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional precautions
listed below. If the beads do not seat at the maximum pressure
indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft (3.66 m) away from the tire
wheel assembly.
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
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

The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-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.
WARNING: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,
seeInflating your tiresin 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 a TPMS
Each road tire is equipped with
a tire pressure sensor located
inside the tire/wheel cavity. The
pressure sensor is attached to
the valve stem. The pressure
sensor is covered by the tire and
is not visible unless the tire is
removed. Care must be taken
when changing the tire to avoid
damaging the sensor.It is
recommended that you always have
your tires serviced by an authorized dealer.
The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer toInflating your tiresin this chapter.

•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTracsystem activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily. Have the system serviced by an authorized dealer immediately.
The AdvanceTracsystem automatically enables each time the engine is
started. All features of the AdvanceTracsystem (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTracsystem includes a stability control light and a stability
control off light in the instrument cluster. Both the stability control light
and the stability control off light in the instrument cluster will illuminate
temporarily during start-up as part of a system self-check. The stability
control light may illuminate during certain driving situations which may

Activating HSA
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the HSA system
will be activated automatically in D (Drive) uphill or R (Reverse)
downhill.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately two to three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
Note:If the engine is revved excessively, HSA will be deactivated.
Deactivating hill start assist
To deactivate HSA, perform one of the following:
•Apply the parking brake.
•Drive off uphill without re-applying the brake.
•Wait for two to three seconds until the HSA system deactivates
automatically.
•If hill start assist is active in D (Drive), select R (Reverse).
•If hill start assist is active in R (Reverse), select N (Neutral).
Note:The HSA warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If a malfunction is
detected in the HSA system, HSA will be deactivated and this warning
lamp will appear on the instrument cluster.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
