1. Bring the vehicle to a rolling speed of
3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Move the 4WD switch to the desired
mode.
The information display will display a
message indicating a 4X4 shift is in
progress. The information display will then
display the system mode selected. If any
of the above shift conditions are not
present, the shift will not occur and the
information display will display information
guiding the driver through the proper
shifting procedures. If the above conditions
are not satisfied in 30 seconds, the system
reverts back to the previous 4WD mode or
drive mode.
If Shift Delayed Pull Forward is displayed
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.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
