•
The knee airbag(s) may deploy based
on crash severity and occupant
conditions.
• The Safety Canopy inflates in certain
side impact crashes or rollover events.
The Safety Canopy may activate in
other types of crashes if the vehicle
experiences sufficient sideways motion
or deformation, or a certain likelihood
of rollover.
Airbags and Police Equipment 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:
Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment. Failure to
follow this instruction could result in
personal injury or death.
Dual driver and passenger airbags, side
airbags and knee airbags affect the way
police equipment can be mounted in police
vehicles.
Any surfaces that could come into contact
with an airbag, once it has deployed, must
not damage the airbag or alter its
deployment path. Once the airbag has fully deployed, any
peripheral equipment surfaces that could
come into contact with the airbag, such as
when the airbag deflates with the loading
of an occupant, must not damage the
airbag or alter its deployment path. Sharp
edges, corners or protrusions could
damage the nylon airbag material and
reduce the effectiveness of the airbag.
Some approximate dimensions for airbags,
at full inflation, are provided. These
dimensions are somewhat flexible and
represent free form deployments without
the loading of occupants. The shaded
areas in Figures 8 through 10 represent
available police equipment mounting
zones. These zones are shown for police
vehicles with standard bucket seats. The
zone dimensions provided in Figures 8
through 10 are approximate and will vary
with the loading of occupants in the seats.
All airbag and equipment mounting zone
dimensions are approximate due to
different airbag deployment
characteristics.
Do not mount equipment between the side
of the front seat and the door trim that will
block deployment of the side airbag.
Do not mount equipment between the
seats and the body side as shown in Figure
7 that would prevent the side curtain airbag
from achieving occupant coverage.

CONNECTING A TRAILER
PRECAUTIONS
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
Consult your local motor vehicle laws for
towing a trailer.
See the instructions included with towing
accessories for the proper installation and
adjustment specifications.
Service your vehicle more frequently if you
tow a trailer. See
Normal Scheduled
Maintenance (page 667).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as
part of your vehicle load when calculating
the total vehicle weight.
Do not exceed the load limits. See
Calculating the Load Limit
(page 415).
HITCHES
HOOKING UP A TRAILER USING A
WEIGHT-DISTRIBUTING HITCH WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may
cause unpredictable handling, and could
result in serious personal injury.
A weight-distributing hitch helps distribute
tongue load to all towing vehicle and trailer
wheels. For more information, visit the links
in the following table. Website

CONNECTING A TRAILER
Recognizing a Trailer
1. Attach the trailer and wiring connector
to your vehicle.
2. Switch on your vehicle.
3. Set up a profile for the trailer using the
touchscreen.
Note: If your vehicle does not recognize the
trailer, press and hold the brake pedal for a
few seconds.
Note: Trailer profiles store trailer types,
dimensions, preferences, trailer specific
mileage and fuel economy.
Note: Disabling the trailer detection
notification makes the default trailer profile
active when the system detects a
connection.

What does it mean if the system
displays that it is not available?
There could be a sub-system that the
system uses that is not correctly
operating or there could be a battery
voltage issue. If the system continues
to display it is not available, visit your
authorized dealer to have your vehicle
checked.
What does it mean if the system
displays that driving is required to
initialize steering? The steering system needs to learn
internal parameters to fully turn on the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes. This could
also occur when your vehicle is new,
there is a battery voltage issue or if the
steering system has been serviced.
What does it mean if the system does
not detect a trailer when configured
with a sensor? Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 448). Repeat
calibration on a different route if you
have verified sensor installation.
What does it mean if the system
requires you to pull forward to
initialize? This occurs when the vehicle has not
moved during the current key cycle
after you connect and select the trailer
in the touchscreen or you operate the
system at speeds below
1 mph
(1 km/h) for an extended period of
time. Drive forward above 2 mph
(3 km/h) and the system indicates
when it initializes. What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle?
You are at the maximum controllable
trailer angle for the system. Place your
vehicle in drive (D) and pull forward to
get the truck and trailer back to an
in-line position. If this message
consistently displays, this could
indicate the sensor is incorrectly
installed, the trailer needs to be
recalibrated or the drawbar or the
trailer dimensions are outside of the
supported range. The system is
designed to work with drawbars that
have a license plate to hitch ball center
measurement of
9–18 in (23–46 cm)
when installed. The system is designed
to work with trailers that have a hitch
point to center of the axle or axles
measurement of
6– 33 ft
(1.85– 10.05 m). Do not attempt to use
drawbars or trailers that have a length
outside of this range as the system
performance degrades and could
cause improper system function.
Check that the correct trailer is
selected in the touchscreen. Verify the
sensor is installed according to the
instructions included in the sensor kit
and check that the drawbar and the
trailer dimensions are within the
allowed range. Then, delete the trailer
from the system and repeat the setup
process to calibrate the trailer.

OFF-ROAD DRIVING
WHAT IS OFF-ROAD DRIVING
Off-road driving is driving your vehicle on
unsurfaced roads or trails, made from dirt,
rocks, sand and mud.
OFF-ROAD DRIVING
PRECAUTIONS - RAPTOR
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
Before going off-road driving, consult with
all the appropriate government entities to
determine where you are legally allowed
to operate your vehicle and what permits
or registrations are required to do so.
Inspect your vehicle before and after any
off-road driving.
Familiarize yourself with the dimensions
of your vehicle including approach angles,
breakover angles, and ground clearance.
Also familiarize yourself with the features
of your vehicle. Some of these features
such as drive modes and cameras can
improve your off-road driving experience.
Secure loose objects inside your vehicle
and in the cargo area.
BASIC OFF-ROAD DRIVING
TECHNIQUES - RAPTOR
Grip the steering wheel with your thumbs
on the outside of the rim. This reduces the
risk of injury due to abrupt steering wheel
motions that occur when negotiating rough
terrain. If you are driving in a dusty area, be sure to
leave ample distance between your vehicle
and any other vehicles to allow for
adequate vision.
BASIC OFF-ROAD DRIVING
TECHNIQUES
Off-road Driving Hints
Before taking your vehicle off-roading, a
basic vehicle inspection should be done to
make sure that the vehicle is in top working
condition. It is always recommended that
at least two vehicles are used while
off-roading. The buddy system helps make
sure that help is close at hand should a
vehicle become stuck or damaged. It is also
wise to take supplies such as a first aid kit,
supply of water, tow strap, cell or satellite
phone with you any time an off-road
excursion is planned.
1. Grip the steering wheel with thumbs
on the outside of the rim. This will
reduce the risk of injury due to abrupt
steering wheel motions that occur
when negotiating rough terrain.
2. Throttle, brake and steering inputs should be made in a smooth and
controlled manner. Sudden inputs to
the controls can cause loss of traction
or upset the vehicle, especially while
on loose terrain or while crossing
obstacles such as rocks or logs.
3. Look ahead on your route noting upcoming obstacles, or any other
factors which may indicate a change
in available traction, and adjust the
vehicle speed and route accordingly.
4. When driving off-road, if the front or rear suspension is bottoming out
and/or excessive contact with the
skid-plates is encountered, reduce
vehicle speed to avoid potential
damage to the vehicle.
