Note:
The information display may show
messages during 4WD operation. See
Information Messages (page 123).
Your 4X4 control is located in one of the
following locations:
• On the instrument panel.
• On the
DRIVE MODE selection switch.
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: 2H may turn on or off automatically
based on Drive Mode selection. See
Drive
Control (page 261).
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: 4A may turn on or off automatically
based on Drive Mode selection. See
Drive
Control (page 261). 4H - 4X4 HIGH
Provides electronically locked four-wheel
drive power to 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:
4H 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/Ruts and Sand Drive Modes even when
the indicator lamp shows 4A. See
Drive
Control (page 261).
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 grades, or pulling heavy
objects. 4L - 4X4 low does not engage
when your vehicle is moving above
3 mph
(5 km/h); this is normal and should be no
reason for concern. Refer to Shifting to or
from 4L - 4X4 low for proper operation.
Note: 4L may turn off automatically based
on Drive Mode selection. See
Drive Control
(page 261).
Shifting Between 4WD System Modes
Note: Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement and
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.

(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 123).
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.

(page 302).
HILL START ASSIST WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. 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.
Note: If the engine is revved excessively, or
if a malfunction is detected, the system will
be deactivated.
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 will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes release automatically

when the engine has sufficient torque to
prevent your vehicle from rolling down the
grade. 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 will activate automatically on
any slope that will cause significant vehicle
rollback. For vehicles with a manual
transmission, you can switch this feature
off using the information display. See
Information Displays (page 111). The
system will remain on or off depending on
how it was last set.
Note: There is no warning lamp to indicate
the system is either on or off.
Note: If your vehicle is equipped with Auto
Hold, Hill Start Assist will not be available
while Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a complete standstill. Keep the brake pedal
pressed and select an uphill gear (for
example, drive (D) or first (1) when
facing uphill or reverse (R) when facing
downhill).
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time will automatically be extended if
you are in the process of driving off.
4. Drive off in the normal manner. The brakes will release automatically. Switching the System On and Off
You can switch this feature on or off if your
vehicle is equipped with a manual
transmission and an information display.
See
General Information (page 111). The
system remembers the last setting when
you start your vehicle.
If your vehicle is not equipped with a
manual transmission and an information
display, you cannot turn the system on or
off. When you switch the ignition on, the
system automatically turns on.

Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)
