WHAT IS HILL DESCENT CONTROL
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as ice
or extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of
vehicle control, crash or serious injury.
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
Note:The system does not function below
3 mph (5 km/h).
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.The system can maintain vehicle speeds on
downhill slopes between 3–20 mph
(5–32 km/h). Above 20 mph (32 km/h), the
system remains on but the descent speed
cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The amount
of time that the system can remain active
before cooling varies with conditions. The
system provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed.
SWITCHING HILL DESCENT
CONTROL ON AND OFF
You can switch the hill descent control on
and off through the touchscreen.
SETTING THE HILL DESCENT
SPEED
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
WARNING: The system does not
control speed in low traction conditions or
extremely steep slopes. 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 personal injury.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.

PRINCIPLE OF OPERATION
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,
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.
Note:If your vehicle has MyKey™, the sensing
system cannot be switched off when a
MyKey™ is present. See Principle of
Operation (page 78).Note:Keep the sensors on the bumper or
fascia 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:If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
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 may block the normal detection zone
of the system. Remove the add-on device to
prevent false alerts.
Note:When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert.The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
touchscreen, information display or from the
pop-up message that appears once you shift
the transmission into reverse (R). If your
vehicle has a parking aid button, you can
switch the system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.
See Information Messages (page 142).

E71621
When driving on a different line
than the vehicle in front. AB With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road. C
In these cases, the system may brake late or
unexpectedly.
If something hits the front end of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detection.

Trailer Lamps
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights,
direction indicators and hazard flashers are
working.
Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your
vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park
(P).
4. Place wheel chocks in front and back of
the trailer wheels. (Chocks not included
with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:Disconnect the wiring to the trailer
before backing the trailer into the water.
