USING FOUR-WHEEL DRIVE
Note:The 4WD temporarily disabled
message will be displayed if the 4WD
system has overheated and defaulted to
front-wheel drive. This condition may occur
if the vehicle is operated in extreme high
load conditions or with excessive wheel slip,
such as deep sand. To resume normal 4WD
function as soon as possible, stop the
vehicle in a safe location and turn off the
engine. The 4WD restored message will be
displayed for approximately five seconds
after the system cools and normal 4WD
function returns.
Note: The Intelligent 4WD system gives
your vehicle some limited off-road
capabilities. Operating your vehicle in
conditions other than moderate sand, snow,
mud or rough roads could subject it to
excessive stress which might result in
damage. This damage is not covered under
your warranty.
Note: When a 4WD system fault is present,
the warning 4WD malfunction Service
required will display in the information
display. The 4WD system is not functioning
correctly and defaulted to front-wheel drive.
When this warning is displayed, have your
vehicle serviced at an authorized dealer.
You will be able to see the power
distribution between the front and rear
wheels represented by an icon in your
information display. More power to either
front or rear wheels will be displayed by
more area filled in. Your vehicle may be equipped with a
full-time four-wheel drive (4WD) system.
The 4WD system is a proactive system,
meaning it not only responds to wheel slip
between the front and rear wheels but also
has the ability to anticipate wheel slip and
transfer torque to the rear wheels before
slip occurs. Even when no wheel slip is
present, the Intelligent 4WD system is
continuously making adjustments to the
torque distribution, in an attempt to
improve the vehicle
’s straight line and
cornering behavior, both on and off road.
The system is active all the time and
requires no input from the operator.
All components of the Intelligent 4WD
system are sealed for life and require no
maintenance.
If your vehicle is equipped with Intelligent
4WD, a spare tire of a different size other
than the tire provided should never be
used. If the spare tire is installed, the 4WD
system may disable automatically and
enter front-wheel drive only mode to
protect driveline components. This
condition may be indicated by a 4WD Off
message in the Information displays
chapter. See Information displays in the
Instrument Cluster chapter for more
information. If there is a 4WD Off message
in the information display from using the
spare tire, this indicator should turn off
after reinstalling the repaired or replaced
normal road tire and driving a short
distance. It is recommended to reinstall
the repaired or replaced road tire as soon
as possible. Major dissimilar tire sizes
between the front and rear axles could
cause the 4WD system to stop functioning
and default to front-wheel drive or damage
the 4WD system.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING
When a wheel is installed, 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. Ensure that any fasteners that
attach the rotor to the hub are secured 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
the vehicle is in motion, resulting in loss of control.

recommended replacement fasteners.
Retighten the lug nuts to the specified torque within 100 miles (160 km) after any wheel
disturbance (tire rotation, changing a flat tire, wheel removal, etc.).
