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. For more information regarding the
system information messages, See
Information Messages (page 125).
Locking Function
(If Equipped) The lock button engages
‘locker
mode ’.
With the locker engaged, the system
electronically locks the differential causing
both half shafts to turn at the same rate.
This increases traction during off road
events.
The locker mode may automatically
disengage based on certain conditions
such as vehicle speed. When engaged, a
telltale in the instrument cluster will
illuminate amber and the switch button
will be illuminated. When the speed is
exceeded the telltale will turn gray, the
locker will be disengaged and be in
standby mode until the speed conditions
are met. If the eLSD system is faulted and
the locker cannot engage, a warning
message will be displayed in the
instrument cluster and the switch button
will flash. Spare Tire
If your vehicle is equipped with an
Electronic Limited Slip Differential, a spare
tire of a different size than the tire
provided, should not be used. 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 grades, 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 64).
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). See General
Information
(page 113).
If a fault is present in the system, a warning
message appears in the information
display and does not allow you to switch
the system on. See
Information
Messages (page 125).
If a sensor is blocked and cannot function,
the system becomes disabled and a
warning message appears in the
information display. The system returns to
a normal state once the blockage is
cleared.

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

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.
The camera may not operate correctly
under the following conditions:
• Nighttime or dark areas if one or both
reverse lamps are not operating.
• Mud, water or debris obstructs the

length less than 33 ft (10.1 m)?
If no, the system turns off.
If yes, the menu goes to the next screen.
• Trailer width measurement:
The width of the trailer is measured at the
front of the trailer. It is not measured at the
widest point of the trailer. The maximum
width at the front of the trailer that the
system can support is
8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is
8.5 ft (2.6 m)
or less.

The trailer length is the distance between
the trailer hitch ball and the rear of the
trailer. The maximum length that the
system can support is
33 ft (10.1 m).
• Enter length of trailer:
The default setting is
18 ft (5.5 m).
Toggling up or down using the menu
buttons increases or decreases the
measurement by
3 ft (1 m). Select a length
that is equal to or within 3 ft (1 m) of the
actual measured length. For example, if
the actual measured length is 25 ft (7.6 m),
toggle the length in the menu to
27 ft
(8.2 m). When you enter the length of the
trailer, the system setup is saved.
Note: If the trailer is actually a bike rack or
cargo rack with electrical lighting, enter a
length of
3 ft (1 m). Cross Traffic Alert
remains on for trailers with a length of 3 ft
(1 m) or less.
Note: Proper measurement and
measurement entry is required for the
system to function as designed. System Operation
When you connect a trailer to your vehicle,
the trailer set up menu appears in the
information display. This menu allows you
to set up a new trailer or choose from a
previously set up trailer. A warning

if you do not choose or add a new trailer.
Note:
The warning message may not
appear until your vehicle speed reaches
22 mph (35 km/h)
.
If you select a trailer in the information
display before connecting a trailer to your
vehicle, the system loads the configuration
for the selected trailer. When a trailer is
connected, a warning message appears.
Note: A second warning message may
appear stating that the Cross Traffic Alert
system has turned off. The Blind Spot
Information System with Trailer Tow
continues to function normally in this
situation.
Note: The system remembers the last
selected trailer set up when you start your
vehicle.
Trailer Considerations
The system is designed to work with a
trailer with a front width of
8.5 ft (2.6 m)
or less, and a total length from the trailer
hitch ball to the rear of the trailer of
33 ft
(10.1 m) or less.
Some trailers may cause a slight change
in system performance:
• Large box trailers may cause false
alerts to occur when driving next to
infrastructures or near parked cars. A
false alert may also occur while making
a 90-degree turn.
• Trailers that have a width greater than
8.5 ft (2.6 m)
at the front and have a
total length greater than 20 ft (6 m)
may cause delayed alerts when a
vehicle is passing at high speed.
