Shifting to or from 4L - 4X4 LOW
Note:
4L mode is not intended for use on dry
pavement.
1. Bring the vehicle to a rolling speed of 3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desired mode.
The information display shows a message
indicating a 4X4 shift is in progress. The
information display shows the system mode
selected. If any of the previous shift
conditions are not present, the shift does not
occur and the information display shows the
information guiding the driver through the
proper shifting procedures. If the previous
conditions are not satisfied in 30 seconds,
the system reverts back to the previous 4WD
mode or drive mode. If
Shift Delayed Pull Forward displays in the
information display, transfer case gear tooth
blockage is present. To alleviate this
condition, place the transmission in a forward
gear, move the vehicle forward
approximately
5 ft (2 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift.
Operating 4WD Vehicles with Spare or
Mismatched Tires
On four-wheel drive vehicles, the size of the
spare tire can affect the 4X4 system. If there
is a significant difference between the size
of the spare tire and the remaining tires, you
may have limited four-wheel drive
functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the vehicle
is stationary.
• Use a 4WD mode on dry pavement. Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
•
Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
How Your Vehicle Differs from Other
Vehicles WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.

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: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It’ s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’ s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions: •
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:

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

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.
