HOW DOES FOUR-WHEEL
DRIVE WORK - RAPTOR
The 2-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 2-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive
auto, four-wheel drive high, and four-wheel
drive low as available modes of operation.
When four-wheel drive auto is selected,
the system continuously varies power to
the front wheels for optimum performance
for all on-road conditions. When either
four-wheel drive high or four-wheel drive
low are selected, the system provides
mechanically locked power to the front
and rear wheels for use in off-road or
slippery conditions such as deep snow,
sand or mud. Selecting four-wheel drive
low also provides additional gearing for
increased torque multiplication for
conditions like deep sand, steep slopes, or
pulling heavy objects. Additionally, the
system is capable of recreational flat
towing by putting the transfer case into
neutral (N). See Recreationally Towing
Your Vehicle (page 490).
There is further information on driving in
unique driving conditions.

•
Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked four-wheel drive mode.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
Mechanical Shift Blocking
On four-wheel drive vehicles with a
mechanically locked four-wheel drive high
mode, the transfer case distributes torque
to the front wheels by mechanically
interlocking the front and rear driveshafts
together. Various external factors can
affect shifting performance of this type of
system including, but not limited to:
• Vehicle acceleration.
• Dissimilar tire sizes.
• Steering input.
If the system detects a mechanical shift
blockage at speed after you select
two-wheel drive high, the message "4x4
Unable to Disengage See Manual", could
display momentarily. If this message
displays, one or more of the following
actions can relieve the mechanical shift
block:
• Momentary acceleration.
• Momentary braking.
• Bringing the vehicle to a stop.
• Shifting the transmission to neutral and
back to drive.
• Shifting the transmission to reverse
and back to drive.
• Driving the vehicle around a tight turn
at a slow speed. SELECTING A FOUR-WHEEL
DRIVE MODE - RAPTOR
The four-wheel drive mode control is on
the instrument panel.
To select a four-wheel drive mode, press
the four-wheel drive mode control button
of the desired mode. You can select
two-wheel drive high (2H), four-wheel
drive high (4H), or four-wheel drive auto

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to
pull away when your vehicle is on a slope
without using the parking brake.
HOW DOES HILL START
ASSIST WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake
pedal to the accelerator pedal. The brakes
release when the engine has developed
sufficient torque to prevent your vehicle
from rolling down the slope.

Side Wind Stabilization
Side wind stabilization is an advanced
feature that works by carefully applying
the brakes on one side of the vehicle to
reduce the effect of a side wind gust on
the vehicle's path.
Torque Vectoring by Brakes
Torque vectoring control applies brake
torque on the inner driven wheel in a curve
for better traction to avoid an understeer,
or oversteer situation. Unlike electronic
stability control, enhanced torque
vectoring control does not slow the
vehicle. It helps control excessive wheel
slip and gives the vehicle improved
cornering agility.
Traction Control
Traction control enhances your vehicle
’s
ability to maintain traction of the wheels
by detecting and controlling wheel spin.

LANE CENTERING
HOW DOES LANE CENTERING
WORK
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the middle of the lane
by applying continuous assistance steering
torque input toward the lane center on
highways.
Note: The adaptive cruise control gap
setting operates normally.
If you drive off-center within the lane, the
system sets and maintains that preferred
lane position. The system provides
continuous assistance steering torque
input toward the preferred position.
Note: The system can only set preferred
lane positions within the lane.
Note: If the system cancels, the preferred
position erases. On the next activation, the
system provides continuous assistance
steering torque input toward the lane center. LANE CENTERING PRECAUTIONS WARNING: Do not use the system
when towing a trailer. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
