WHAT IS THE ELECTRONIC
LIMITED-SLIP DIFFERENTIAL
The electronic limited-slip differential 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 display in the
instrument cluster. Depending on the
warning, you may need to service your
vehicle. Operating the Electronic Limited-Slip
Differential with a Spare or Mismatched
Tires
If your vehicle has an electronic limited-slip
differential, do not use a spare tire of a
different size than the tire provided. If you
have a spare tire installed, a message may
appear indicating the system has disabled
automatically or reduced function to prevent
system overheat and damage. We
recommend you reinstall the repaired or
replaced spare tire as soon as possible.
When you replace the spare tire, the system
resumes 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
reaches normal operating temperatures,
system function restores and the electronic
limited-slip differential restored message
displays.

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to pull
away when your vehicle is on a slope without
using the parking brake.
HOW DOES HILL START ASSIST
WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake pedal
to the accelerator pedal. The brakes release
when the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope.
HILL START ASSIST PRECAUTIONS
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. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. HILL START ASSIST –

ELECTRIC POWER STEERING
ELECTRIC POWER STEERING
PRECAUTIONS
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
vehicle off. After at least 10 seconds, switch
the vehicle on and watch the information
display for a steering system warning
message. If a steering system warning
message returns, have the system checked
as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control. Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle manually
nor will it cause damage to the system.
Normal steering and driving allows the
system to cool down and steering assist
returns to normal.
Note:
There is no fluid reservoir to check or
fill.
ELECTRIC POWER STEERING
ADAPTIVE STEERING
(If Equipped)
The adaptive steering system changes the
steering ratio with changes to vehicle speed,
optimizing the steering response in all
conditions. The system also changes when
you switch on the transmission tow/haul
feature. When you select the tow/haul button,
the adaptive steering system reduces vehicle
sensitivity to steering inputs at higher vehicle
speeds, while maintaining the ease of
parking and maneuverability at low speeds. Note:
The adaptive steering system
continuously monitors for faults. If the system
detects a fault, a message appears in the
information display. If a red warning
message displays, stop your vehicle as soon
as it is safe to do so. The message could
clear if the fault is no longer present. If an
adaptive steering system warning message
appears each time you start your vehicle,
have the system checked as soon as
possible.
Note: The system has a locking device. It
remains mechanically locked at a fixed
steering ratio with the lock engaged. You
may notice a click when you turn your
vehicle on or off.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system shuts down and you retain a normal
steering function with a fixed steering ratio.
During this time, it is possible that the
steering wheel could not be straight when
the vehicle is driving straight ahead. In
addition, you could notice that the steering
wheel angle required to steer your vehicle
could be different.

Note:
During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device could engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to normal
operation. Adaptive Learning
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the brake
system to help operate advanced stability
control and crash avoidance systems.
Additionally, whenever you disconnect the
battery or install a new battery, you must
drive your vehicle a short distance before
the system relearns the strategy and
reactivates all systems.STEERING – TROUBLESHOOTING
STEERING – WARNING INDICATORS The adaptive steering system
indicator illuminates if the system
detects a fault during the
continuous diagnostic checks.
Note: If a red warning message displays,
stop your vehicle as soon as it is safe to do
so.
