Brake System Warning Lamp
WARNING: Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury. It illuminates when you engage
the parking brake and the
ignition is on.
If it illuminates when your vehicle is
moving, make sure the parking brake is
disengaged. If the parking brake is
disengaged, this indicates low brake fluid
level or a brake system fault. Have your
vehicle checked as soon as possible.
Cruise Control Indicator It illuminates when you switch
the system on.
See
What Is Cruise Control
(page 246).
Direction Indicator Illuminates when you switch on
the left or right direction
indicator or the hazard flashers.
Flashes during operation. An increase in
the rate of flashing warns of a failed
indicator bulb.
Door Ajar Warning Lamp Displays when the ignition is on
and any door is not completely
closed. Electric Park Brake Illuminates or flashes when the
electric parking brake has a
condition that requires service.
See
Electric Parking Brake (page 220).
Electronic Limited Slip Differential
(If Equipped) Illuminated when using the
locking function of the electronic
limited slip differential.
Engine Coolant Temperature
Warning Lamp If it illuminates when your vehicle
is moving, this indicates that the
engine is overheating. Stop your
vehicle as soon as it is safe to do so and
switch the engine off. Have your vehicle
checked as soon as possible.
Fasten Seatbelt Warning Lamp It illuminates and a tone sounds
until you fasten the seatbelts.

Displays if the electronic limited slip differential has limited func-tionality. This could be due to an undersized spare tire or caused
by the system overheating. If an undersized spare tire is installed, replace the spare tire with a full-sized tire as soon as possible. Ifan undersized spare tire is not installed, the vehicle has reduced functionality. Have your vehicle checked as soon as possible.

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 129).
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.
