LIMITED SLIP DIFFERENTIAL (IF
EQUIPPED)
The Electronic Limited Slip Differential (eLSD)
system directs torque, enabling the vehicle
to drive over terrain and road conditions that
a conventional axle cannot. The system is
active at all times and requires no input from
the driver.
Note: If your vehicle is not at optimal
operating conditions or a system fault is
present, a warning may be displayed in the
instrument cluster. Depending on the
warning, your vehicle may need to be
serviced. You can find more information
regarding the system information messages
in the Information Displays chapter.
See
Information Messages (page 138).
Spare Tire
If your vehicle has an Electronic Limited Slip
Differential, do not use a spare tire of a
different size than the tire provided. If a spare
tire is installed, a message may appear,
indicating the system has disabled
automatically or reduced function to prevent system overheat and damage. It is
recommended to reinstall the repaired or
replaced road tire as soon as possible. When
the road tire is replaced, the system will
resume normal operation on the next key
cycle.
Trailer Towing
The Electronic Limited Slip Differential
enhances vehicle stability during trailer tow
operation. During high demand trailering
events, such as steep slopes, high speeds
or with a spare tire, the system may provide
a warning in the instrument cluster and
reduce function or enter a temporarily
disabled state. To resume normal function,
stop the vehicle in a safe location and allow
the unit to adequately cool. Once the system
has reached normal operating temperatures,
system function will be restored and the
Electronic Limited Slip Differential Restored
message will be displayed.

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:
Certain add-on devices installed
around the bumper or fascia may create
false beeps. 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.
Note: Keep the sensors, located 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 alarms. See your
authorized technician.
Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 78).
We recommend that you take some time to
get to know the system and its limitations by
reading this section.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system automatically turns on
each time you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the radio
volume returns to the previous level. You can turn the system on or off
by pressing the parking aid button.
If your vehicle does not have a
parking aid button, the system can be
switched off through the information display
menu or from the pop-up message that
appears once you shift the transmission into
reverse (R).

WARNING: Active park assist does
not apply the brakes under any
circumstances. 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.
Active park assist is a multi-step process and
may require you to shift the transmission
multiple times. Follow the onscreen
instructions until the parking maneuver is
complete.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose to
override the system by grabbing the steering
wheel, or by taking full control of your vehicle
after pressing the active park assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel when
using active park assist. The sensors are on the front and rear
bumpers.
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: The sensors may not detect objects
with surfaces that absorb ultrasonic waves.
The sensors may falsely detect objects due
to ultrasonic interference caused by
motorcycle exhausts, truck air brakes or
horns, for example.
Note: If you change any tires, the system
must recalibrate and may not correctly
operate for a short time.
The system may not correctly operate in any
of the following conditions:
• You use a spare tire or a tire that is
significantly worn more than the other
tires.
• One or more tires are incorrectly inflated.
• You try to park on a tight curve. •
Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow, fog,
high humidity and high temperatures.
Do not use the system if:
• You have attached an add-on accessory
close to the sensors on the front or rear
of your vehicle. For example, a bike rack
or trailer.
• You have attached an overhanging
object to the roof. For example, a
surfboard.
• The front bumper, rear bumper or the
side sensors are damaged.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.

WARNING: Use caution when the
rear cargo door is ajar. If the rear cargo
door is ajar, the camera will be out of
position and the video image may be
incorrect. All guidelines disappear when
the rear cargo door is ajar. Failure to follow
this instruction could result in personal
injury. WARNING:
Use caution when turning
camera features on or off when the
transmission is not in park (P). Make sure
your vehicle is not moving.
The rear view camera system provides a
video image of the area behind your vehicle.
During operation, lines appear in the display
which represent your vehicle ’s path and
proximity to objects behind your vehicle. The camera is located on the luggage
compartment door, above the license plate.
Using the Rear View Camera System
The rear view camera system displays what
is behind your vehicle when you place the
transmission in reverse (R).
Note:
The reverse sensing system is not
effective at speeds above
3 mph (5 km/h)
and may not detect certain angular or
moving objects. The system uses three types of guides to
help you see what is behind your vehicle:
•
Active guidelines (if equipped): Show the
intended path of your vehicle when
reversing.
• Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another object
behind you.
• Centerline: Helps align the center of your
vehicle with an object. For example, a
trailer.
Note: If the transmission is in reverse (R) and
the luggage compartment door or liftgate is
open, no rear view camera features display.
Note: When towing, the camera only sees
what you are towing. This might not provide
adequate coverage as it usually provides in
normal operation and some objects might
not be seen. In some vehicles, the
guidelines may disappear when you connect
the trailer tow connector.
