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.
HILL START ASSIST
PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system will turn
off if a malfunction is apparent. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. HILL START ASSIST –

WHAT IS TRACTION CONTROL
The traction control system helps to avoid
drive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss of
traction can compromise steering control
and stability of the vehicle. The traction
control system applies the brakes to
individual wheels and when needed,
reduces engine power at the same time to
increase traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. The traction control system turns on each
time you switch the ignition on.
The button for the stability and traction
control system is on the instrument panel. Press and release the button to switch
traction control off. The stability control
system remains fully active, to switch it off,
press and hold the button for a few
seconds, then release.
When you switch traction control off, a
message and an illuminated icon appear
on the instrument cluster.
Press the switch again to turn the traction
control system back on to normal
operation.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Your vehicle may have MyKey restrictions
regarding this feature. See
What Is
MyKey (page 98).

INDICATOR
Stability and Traction Control
Indicator If the indicator does not
illuminate when you switch the
ignition on, or remains on when
the engine is running, this indicates a
malfunction. Have your vehicle checked
by an authorized dealer as soon as
possible. The traction control off indicator
illuminates when you switch the
traction control system off, or
when an alternative stability control mode
is selected that requires the traction
control off depending on the drive mode
selected.

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.

TOW/HAUL - RAPTOR For improved transmission
operation when towing a trailer
or a heavy load. This mode
moves upshifts to higher engine speeds to
reduce the frequency of transmission
shifting. This mode also provides engine
braking in all forward gears, which slows
your vehicle and assists you in controlling
your vehicle when descending a slope. The
amount of downshift braking provided
varies based on the amount you press the
brake pedal.
All four-wheel drive modes are selectable
when in tow/haul mode. This mode does
not default to a certain four-wheel drive
mode and maintains the previous
selection.
