Releasing the Electric Parking
Brake if the Vehicle Battery is
Running Out of Charge
Connect a booster battery to the vehicle
battery to release the electric parking brake
if the vehicle battery is running out of
charge. See Jump Starting the Vehicle
(page 301).
HILL START ASSIST 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 or if you
rev the engine excessively. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:
There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.

WHAT IS REVERSE BRAKING
ASSIST
The system is designed to reduce impact
damage or avoid a collision completely by
using the sensors on the rear of your
vehicle. The system functions when in
reverse (R) and traveling at a speed of
1–
7 mph (1.5– 12 km/h).
If the system detects an obstacle behind
your vehicle, it provides a warning through
the rear parking aid or cross traffic alert
system.
REVERSE BRAKING ASSIST
PRECAUTIONS 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. WARNING:
To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. 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:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types,
and pedestrians. Apply the brakes when
necessary. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death.
The system only applies the brakes for a
short period of time when an event occurs.
The driver should take action as soon as
they notice the brakes apply in order to
remain in control of the vehicle.
Note: Certain add-on devices around the
bumper or fascia may create false alerts.
For example, large trailer hitches, bicycle 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: The system does not react to small
or moving objects, particularly those close
to the ground.
Note: The system does not operate during
hard acceleration or steering.

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: Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the
system may detect the trailer and provide
an alert or the system turns off. If the system
does not turn off, switch the system off
manually after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

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 and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
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 Press the button on the center
console. A light illuminates in the
control and a tone sounds when
the system is active.
SETTING THE HILL DESCENT
SPEED WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. 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.
When you reach the speed you prefer,
either by accelerating or decelerating,
remove your feet from the pedals. The
system maintains the chosen vehicle

WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. 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.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
The sensors are on the rear bumper.
The sensors are active when the
transmission is in reverse (R) and the
vehicle speed is less than 3 mph (5 km/h).
When the parking aid system sounds a
tone, the audio system may reduce the set
volume.
A warning tone sounds when your vehicle
approaches an object. As your vehicle
moves closer to an object, the rate of the
tone increases. The warning tone
continuously sounds when an object is 12 in
(30 cm)
or less from the center of the rear
bumper.
Note: There is a decreased coverage area
at the outer corners. The sensor coverage area is up to
70 in
(180 cm) from the rear bumper.
If the system detects a fault, a warning
message appears in the information
display.
The system detects large objects when
you shift into reverse (R) and any of the
following occur:
• Your vehicle is moving backward at low
speed.
• Your vehicle is stationary but an object
is approaching the rear of your vehicle
at low speed.
• Your vehicle is moving backward at low
speed and an object is moving toward
your vehicle, for example another
vehicle at low speed.
If your vehicle remains stationary for two
seconds the audible warning turns off. If
your vehicle moves backward the tone
sounds again.
Note: If the detected object is 12 in (30 cm)
or less from the rear bumper, the audible
warning does not turn off.
