CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt
buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (if equipped), child safety seat
LATCH and tether anchors, and attaching
hardware, should be inspected after a
crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.
We recommend that all seatbelt
assemblies in use in vehicles involved in a
crash be replaced. However, if the crash
was minor and an authorized dealer finds
that the belts do not show damage and
continue to operate properly, they do not
need to be replaced. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 391). SEATBELT EXTENSIONS WARNING:
Persons who fit into
the vehicle's seatbelt should not use an
extension. Unnecessary use could result
in serious personal injury in the event of
a crash. WARNING:
Only use extensions
provided free of charge by our dealers.
The dealer will provide an extension
designed specifically for this vehicle,
model year and seating position. The use
of an extension intended for another
vehicle, model year or seating position
may not offer you the full protection of
your vehicle's seatbelt restraint system. WARNING:
Never use seatbelt
extensions to install child restraints. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.

particularly to occupants who are not
properly restrained or are otherwise out of
position at the time of airbag deployment.
Thus, it is extremely important that
occupants be properly restrained as far
away from the airbag module as possible
while maintaining vehicle control.
Routine maintenance of the airbags is not
required.
DRIVER AND PASSENGER
AIRBAGS
WARNING: Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. The driver and front passenger airbags
deploy during significant frontal and near
frontal crashes.
The driver and passenger front airbag
system consists of:
•
Driver and passenger airbag modules. · Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator
(page 53).
Passenger Airbag On and Off
Switch
(If Equipped) WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING:
The front passenger
airbag is not designed to offer protection
to an occupant in the center seating
position. WARNING:
Your vehicle may have
an airbag deactivation switch. Before
driving, always look at the switch to
make sure it is in the appropriate
position. Failure to put the switch in the
proper position can increase the risk of
serious injury or death in a crash. The front passenger airbag on and off
switch has indicators that illuminate,
indicating that the front passenger frontal
airbag is either on or off. The indicators are
near the center of the instrument panel.
Note:
The OFF and ON indicators illuminate
for a short period of time when you switch
the ignition on to confirm it is functional.

switch is off and you switch the ignition
on, have the passenger airbag switch
serviced immediately by a qualified
technician. WARNING:
To avoid switching on
the airbag, always remove the ignition
key with the switch in the off position. WARNING:
If your vehicle has rear
seats, always transport children who are
12 and younger in the rear seat. Always
use seatbelts and child restraints
properly. Do not place a child in a rear
facing infant seat in the front seat unless
your vehicle is equipped with an airbag
on and off switch and the passenger
airbag is turned off. This is because the
back of the infant seat is too close to the
inflating airbag and the risk of a fatal
injury to the infant when the airbag
inflates is substantial.
The passenger airbag on and off switch is
in the glovebox. 1. Insert the ignition key, turn the switch
to OFF and hold in OFF while removing
the key.
2. When you switch the ignition on, the passenger airbag off light illuminates
briefly, momentarily shuts off and then
switches back on. This indicates that

After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. Properly seated occupants sit
upright, lean against the seat back, and
center themselves on the seat cushion,
with their feet comfortably extended on
the floor. Sitting improperly can increase
the chance of injury in a crash event. For
example, if an occupant slouches, lies
down, turns sideways, sits forward, leans
forward or sideways, or puts one or both
feet up, the chance of injury during a crash
greatly increases.
Children and Airbags
WARNING: Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. 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 crash. If two adults and a child occupy a Regular
Cab, properly restrain the child in the
center front unless doing so would interfere
with driving your vehicle. This provides lap
and shoulder belt protection for all
occupants, and airbag protection for the
adults. A child or infant properly restrained
in the center front seat should not incur
risk of serious injury from the airbags.
SIDE AIRBAGS
WARNING:
Do not place objects
or mount equipment on or near the
airbag cover, on the side of the front or
rear seatbacks, or in areas that may
come into contact with a deploying
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Accessory seat covers
not released by Ford Motor Company
could prevent the deployment of the
airbags and increase the risk of injuries
in a crash. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death.

PRINCIPLE OF OPERATION
MyKey allows you to program keys with
restricted driving modes to promote good
driving habits. You can program the
restrictions to all keys but one. Any keys
that you did not program are administrator
keys or admin keys.
You can use admin keys to:
•
Create a MyKey with certain vehicle
restrictions.
• Program certain MyKey settings.
• Clear all MyKey restrictions.
After you program a MyKey, you can view
the following information through the
information display:
• The total number of admin keys and
MyKeys for your vehicle.
• The total distance a MyKey driver
traveled with your vehicle.
Note: Every MyKey receives the same
restrictions and settings. You cannot
program them individually.
Note: For vehicles equipped with a
push-button start switch: When both a
MyKey and an admin key are present when
you start your vehicle, the system recognizes
the admin key only.
Standard Settings
Not every vehicle includes the features
listed below. If your vehicle has this
equipment, then you cannot change the
following settings when using a MyKey:
• Seatbelt reminder or Belt-Minder™.
MyKey mutes the audio system until
drivers, and in some instances,
passengers, fasten their seatbelts.
• Earlier low-fuel warning. The low-fuel
warning activates earlier for MyKey
drivers, giving them more time to refuel. •
Certain driver alerts, stability systems
or parking aids turn on automatically
when you use the MyKey system. For
example, Blind Spot Information
System (BLIS), cross traffic alert, lane
departure warning or forward collision
warning.
• Restricted touchscreen operation in
some markets. For example, MyKey
may prevent manual navigation
destination input while the vehicle is in
any gear other than park (P) or when
the vehicle reaches a certain rate of
speed.
• Satellite radio adult content
restrictions, if this feature is available
in your market.
Note: MyKey drivers may be able to switch
the lane departure warning feature off, but
this feature turns back on automatically
with every new key cycle.
Note: If your vehicle includes an AM/FM
radio or a very basic audio system, then the
radio may not mute.
Optional Settings
You can configure certain vehicle feature
settings when you first create a MyKey. You
can also change the settings afterward
with an admin key.
Note: Not every feature applies to every
vehicle in every market. When they are
available for your vehicle, then they appear
in your information display, providing
choices to switch them on or off, or to select
a more specific setting.
• Various vehicle speed limits so the
MyKey driver cannot exceed certain
speeds. The information display shows
warnings followed by an audible tone
when the MyKey driver reaches the set
speed. You cannot override the set
speed by fully depressing the
accelerator pedal.
