FOUR-WHEEL DRIVE
PRECAUTIONS WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. 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 won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than an ordinary
passenger car. Always maintain steering
wheel control, especially in rough terrain.
Since sudden changes in terrain can result
in abrupt steering wheel motion, make sure
you grip the steering wheel from the outside. Do not grip the spokes. Drive
cautiously to avoid vehicle damage from
concealed objects such as rocks and
stumps. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE
LIMITATIONS
Operating Four-Wheel Drive with
a Spare or Mismatched Tires
(If
Equipped)
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could have
limited four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, we
recommend that you do not:
• Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Turn on a four-wheel drive mode
unless the vehicle is stationary.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit
four-wheel drive functionality, especially
when driving in a mechanically locked
four-wheel drive mode. You can experience
the following:

WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is a
device housed in the rear axle, and can
provide additional traction when needed.
HOW DOES THE ELECTRONIC
LOCKING DIFFERENTIAL
WORK - RAPTOR
You can activate the differential
electronically and shift it on the fly within
the operating speed range. The electronic
differential disengages when the vehicle
speed exceeds a set value and it reengages
when the vehicle speed goes below a set
value depending on drive mode. See
Switching the Electronic Locking
Differential On and Off (page 303). The
electronic locking differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction.
Note:
The electronic locking differential can
activate or deactivate automatically based
on speed, four-wheel drive mode, and drive
mode selection. See Switching the
Electronic Locking Differential On and
Off
(page 303).
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement results in
increased tire wear, noise and vibration.
Note: The electronic locking differential is
not available in 2H. HOW DOES THE ELECTRONIC
LOCKING DIFFERENTIAL
WORK
You can activate the differential
electronically and shift it on the fly within
the operating speed range. The electronic
differential disengages when the vehicle
speed exceeds a set value, and reengages
when the vehicle speed goes below a set
value. See
Switching the Electronic
Locking Differential On and Off (page
303). It also engages based on certain
selected drive modes. See Selecting a
Drive Mode (page 373). The electronic
locking differential is for use in mud, rocks,
sand, or any off-road condition where you
need maximum traction.
Note: The electronic locking differential can
activate or deactivate automatically based
on speed, four-wheel drive mode, and drive
mode selection.
See Switching the
Electronic Locking Differential On and
Off
(page 303).
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement results in
increased tire wear, noise and vibration.
ELECTRONIC LOCKING
DIFFERENTIAL PRECAUTIONS
Operating the Electronic Locking
Differential with a Spare or
Mismatched Tires
On vehicles with an electronic locking
differential, the size of the spare tire can
affect performance of the system. If there
is a significant difference between the two
rear tires, you may have limited electronic
locking differential functionality. If the
system has difficulty disengaging, release

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo speakers may
interfere with and adversely affect the
electronic stability control system.
Reducing the effectiveness of the
electronic stability control system 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 electronic stability
control system 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. WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.
If a driving condition activates either the
stability control or traction control you may
experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control enhances your
vehicle ’s ability to prevent skids or lateral
slides by applying brakes to one or more
of the wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
Roll stability control enhances your
vehicle ’s ability to prevent rollovers by
detecting your vehicle ’s roll motion and
the rate at which it changes by applying
the brakes to one or more wheels
individually.
Curve Control
Curve control enhances your vehicle ’s
ability to follow the road when cornering
severely or avoiding objects in the roadway.
Curve control operates by reducing engine
power and, if necessary, applying brakes
to one or more of the wheels individually.

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
fluorescent lamps, inclement weather,
air brakes, external motors and fans may
affect the correct operation of the
sensing system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. Note:
If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts.
When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp
objects.
Note: When using a programmed MyKey,
you cannot switch the parking aids off. See
MyKey ™
(page 98).
REAR PARKING AID
(IF EQUIPPED)
WHAT IS THE REAR PARKING AID
