Note:
Four-wheel drive mode availability
is based on drive mode selection. See Drive
Control (page 271).
Note: The information display may show
messages during four-wheel drive operation.
See
Information Messages (page 129).
2H - 4X2
Delivers power to the rear wheels only. The
information display momentarily shows
2H when this mode is selected. This mode
is appropriate for normal on-road driving
on dry pavement and provides the best
fuel economy.
Note: This may turn on or off automatically
based on drive mode selection. See
Drive
Control (page 271).
4A - 4X4 AUTO
Provides electronic controlled four-wheel
drive with power delivered to the front and
rear wheels, as required, for increased
traction. When you select this mode, the
information display shows 4A. The system
continuously monitors road conditions,
driver input as well as other vehicle sensors
and optimizes the system's behavior based
on drive mode selection.
Note: On vehicles with a rotary drive mode
switch, 4A should remain on in Mud/Rut and
Sand but with aggressive tuning, which
provides electronically locked four-wheel
drive power to front and rear wheels, the
same as traditional 4H.
Note: This may turn on or off automatically
based on drive mode selection. See
Drive
Control (page 271). 4H - 4X4 HIGH
Provides electronically locked four-wheel
drive power to the front and rear wheels.
When you select this mode, the
information display shows 4H. This mode
is not recommended for use on dry
pavement. This mode is only intended for
severe winter or off-road conditions, such
as deep snow, ice or shallow sand.
Note:
This may turn on or off automatically
based on drive mode selection. In
configurations with a rotary drive mode
switch, 4H functionality is within the
Mud/Rut and Sand drive modes even when
the indicator lamp shows 4A. See
Drive
Control (page 271).
4L - 4X4 LOW
Provides electronically locked four-wheel
drive power to both the front and rear
wheels with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep slopes, or pulling heavy
objects. Using 4L - 4X4 low does not
engage when your vehicle is moving above
3 mph (5 km/h)
. This is normal and is no
reason for concern.
Note: This may turn off automatically
based on drive mode selection. See
Drive
Control (page 271).
Shifting Between Four-Wheel Drive
System Modes
You can change between 2H to 4A or 4H
at a stop or when driving. The information
display may show a message indicating a
4X4 shift is in progress and the LED light
for the selected mode flashes. Once the
shift is complete, the information display
shows the system mode selected and the
LED light for the selected mode turns solid.

(If Equipped)

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.

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
