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 nylon 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 crash sensors located under the outboard side of the front seats,
attached near the floor.
•Two crash sensors located at the base of the “C” pillars above the
wheel house.
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 or an unbuckled child or small person in the 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 to theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.

Any difficulty with the system is indicated by one or more of the
following:
•The readiness light (same light as used for front airbag system) will
either flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned to the on position.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Disposal of airbags and airbag equipped vehicles
(including pretensioners)
See your authorized dealer. Airbags MUST BE disposed of by qualified
personnel.
SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAirbag supplemental restraint system
(SRS)in this chapter for special instructions about using airbags.
Important child restraint precautions
WARNING:Always make sure your child is secured properly in
a device that is appropriate for their height, age and weight.
Child safety restraints must be purchased separately from the vehicle.
Failure to follow these instructions and guidelines may result in an
increased risk of serious injury or death to your child.
WARNING:All children are shaped differently. The
Recommendations for Safety Restraints are based on probable
child height, age and weight thresholds from NHTSA and other safety
organizations or are the minimum requirements of law. Ford
recommends checking with a NHTSA Certified Child Passenger Safety
Technician (CPST) and your pediatrician to make sure your child seat
is appropriate for your child, and is compatible with and properly
installed in the vehicle. To locate a child seat fitting station and CPST
contact the NHTSA toll free at 1-888-327-4236 or on the internet at
http://www.nhtsa.dot.gov. Failure to properly restrain children in safety
seats made especially for their height, age, and weight may result in an
increased risk of serious injury or death to your child.

Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Pressure Warning Lamp will turn ON if the tire pressure is
significantly low. Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturer’s recommended tire
pressure. Even if the light turns ON and a short time later turns OFF,
your tire pressure still needs to be checked. Visit www.checkmytires.org
for additional information.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the TPMS system will continue to identify an issue to remind you
that the damaged road wheel/tire needs to be repaired and put back on
your vehicle.
To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with TPMS
in this section.

When you believe your system is not operating properly
The main function of the Tire Pressure Monitoring System is to warn you
when your tires need air. It can also warn you in the event the system is no
longer capable of functioning as intended. Please refer to the following

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. 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 recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If

STARTING
Positions of the ignition
1. Off— locks the gearshift lever
and allows key removal. This
position also shuts the engine and
all electrical accessories off.
2. Accessory— allows the electrical
accessories such as the radio to
operate while the engine is not
running.
3. On— all electrical circuits operational. Warning lights illuminated. Key
position when driving.
4. Start— cranks the engine. Release the key as soon as the engine
starts.
Starting your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian Interference-Causing Equipment
standard requirements regulating the impulse electrical field strength of
radio noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
To avoid potential transmission damage at extremely cold temperatures
(below -20°F [-30°C]), it is recommended that the vehicle be warmed up
to normal operating temperature before driving at highway speeds above
50 mph (80 km/h). Normal operating temperature is normally reached
after 10 minutes of moderate driving or idling.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.

How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of energy per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.

ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled and
the ABS light is on, normal braking
is still effective. If your BRAKE
warning lamp illuminates with the
parking brake released, have your
brake system serviced immediately.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance and does not
decrease the time necessary to apply the brakes.
Parking brake
To set the parking brake (1), pull
the parking brake handle up as far
as possible.
The BRAKE warning lamp will
illuminate and will remain
illuminated until the parking brake
is released.
To release, press and hold the button (2), pull the handle up slightly,
then push the handle down.
