PRINCIPLES OF OPERATION
WARNING:Airbags do not inflate slowly or gently, and the risk
of injury from a deploying airbag is the greatest close to the trim
covering the airbag module.
WARNING: All occupants of your vehicle, including the driver,
should always properly wear their safety belts, even when an
airbag supplemental restraint system is provided. Failure to properly
wear your safety belt could seriously increase the risk of injury or
death.
WARNING: Airbags can kill or injure a child in a child seat.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
WARNING: Never place your arm over the airbag module, as a
deploying airbag can result in serious arm fractures or other
injuries.
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 upon which the child seat is installed all the way back.
WARNING: Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses as you could be
seriously injured or killed. Contact your authorized dealer as soon as
possible.
WARNING: Several airbag system components get hot after
inflation. Do not touch them after inflation as this may result in
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 upon which the child seat is installed all the way back.
The driver and front passenger
airbags will 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 later in
this chapter.
Proper Driver and Front Passenger Seating Adjustment
WARNING:The National Highway Traffic Safety Administration
recommends a minimum distance of at least 10 inches (25
centimeters) between an occupant’s chest and the driver airbag module.
To properly position yourself away from the airbag:
• Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
• Recline the seat slightly (one or two degrees) from the upright
position.
After all occupants have adjusted their seats and put on safety belts, 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 is greatly increased.

Children and Airbags
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 upon which the child seat is installed all the way back.
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.
SIDE AIRBAGS
WARNING: Do not place objects or mount equipment on or near
the airbag cover, on the side of the seatbacks (of the front seats),
or in front seat 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: Do not use accessory seat covers. The use of
accessory seat covers may prevent the deployment of the side
airbags and increase the risk of injury in an accident.
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
airbag, its fuses or the seat cover on a seat containing an airbag,
as you could be seriously injured or killed. Contact your authorized
dealer as soon as possible.
Supplementary Restraints System 47
2015 Navigator(nav)
Owners Guide gf, 2nd Printing, December 2014
USA (fus)

The system consists of:
•Safety canopy curtain airbags
located above the trim panels
over the front and rear side
windows identified by wording on
the B-pillar trim.
• A flexible headliner which opens above the side doors to allow air
curtain deployment.
•Crash sensors and monitoring system with readiness
indicator. See Crash Sensors and Airbag Indicator in this
chapter.
Children 12 years old and under should always be properly restrained in
the rear seats. 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 opening.
The design and development of the Safety Canopy 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).
CRASH SENSORS AND AIRBAG INDICATOR
WARNING: Modifying or adding equipment to the front end of
your vehicle (including frame, bumper, front end body structure
and tow hooks) may affect the performance of the airbag system,
increasing the risk of injury. Do not modify the front end of your
vehicle.

Blind Spot Information System (BLIS®) with Cross Traffic Alert
(CTA) (If Equipped)
Refer toBlind Spot Information System (BLIS®) with Cross Traffic
Alert (CTA) in theDriving Aids chapter.
INTERIOR MIRROR
WARNING: Do not adjust the mirror when your vehicle is
moving.
Note: Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum or ammonia based cleaning products.
You can adjust the interior mirror to your preference. Some mirrors also
have a second pivot point. This lets you move the mirror head up or
down and from side to side.
Auto-Dimming Mirror
Note: Do not block the sensors on the front and back of the mirror.
Mirror performance may be affected. A rear center passenger or raised
rear center head restraint may also block light from reaching the sensor.
The mirror will dim automatically to reduce glare when bright lights are
detected from behind your vehicle. It will automatically return to normal
reflection when you select reverse gear to make sure you have a clear
view when backing up.
CHILDMINDER MIRROR (IF EQUIPPED)
On double bin overhead consoles, the conversation mirror allows the
driver to view the rear seating area.
WARNING: Do not use the childminder mirror to view rearward
traffic, do not allow rear passengers to distract you from the
driving task, and make sure the rear view mirror has a clear view of
rearward traffic. Failure to do so could increase the risk of a crash from
an unseen vehicle, which may result in serious injury.

Adjusting the Second-Row Center 20% Seat (If Equipped)
Note:Move this seat forward to keep a child in a child restraint close to
the front seat occupants. Move the seat to the full rearward position
when it is occupied by older children or adults, including children in
booster seats.
Lift the handle to move the seat
forward or backward.
Rear Heated Seats (If Equipped)
WARNING: Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, or other physical conditions,
must exercise care when using the seat heater. The seat heater may
cause burns even at low temperatures, especially if used for long
periods of time. Do not place anything on the seat that insulates against
heat, such as a blanket or cushion, because this may cause the seat
heater to overheat. Do not puncture the seat with pins, needles, or
other pointed objects because this may damage the heating element
which may cause the seat heater to overheat. An overheated seat may
cause serious personal injury.
Note: Do not do the following:
• Place heavy objects on the seat
• Operate the seat heater if water or any other liquid is spilled on the
seat. Allow the seat to dry thoroughly.
The rear seat heat controls are located on the rear of the center console.

GENERAL INFORMATION
Notice to Utility Vehicle, Van and Truck Owners
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
• Avoid sharp turns and abrupt maneuvers.
• Drive at safe speeds for the conditions.
• Keep tires properly inflated.
• Never overload or improperly load your vehicle.
• Make sure every passenger is properly restrained.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts. Children and infants must use
appropriate restraints to minimize the risk of injury or ejection.
Utility vehicles, vans and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles, vans and
trucks are not designed for cornering
at speeds as high as passenger cars
any more than low-slung sports cars
are designed to perform satisfactorily
under off-road conditions.
Four-Wheel Drive System (If Equipped)
WARNING: Do not become overconfident in the ability of
four-wheel drive vehicles. Although a four-wheel drive vehicle
may accelerate better than a two-wheel drive vehicle in low-traction
situations, it will not stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
A vehicle equipped with four-wheel drive (when selected) has the ability
to use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
