Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than an ordinary
passenger car. Always maintain steering
wheel control, 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. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
Note: Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. Four-wheel
drive high or four-wheel drive low mode is
only intended for consistently slippery or
loose surfaces. Use of four-wheel drive low
mode on these surfaces could produce
some noise, such as occasional clunks, but
should not damage drive components.
When transitioning from consistently loose
or slippery surfaces, be sure the four-wheel
drive system is not mechanically blocked
once on dry, hard surfaced roads in
two-wheel drive high.
FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. four-wheel
drive high or four-wheel drive low mode is
only intended for consistently slippery or
loose surfaces. Use of four low mode on
these surfaces could produce some noise
,such as occasional clunks, but should not
damage drive components. When
transitioning from consistently loose or
slippery surfaces, be sure the four-wheel
drive system is not mechanically blocked
once on dry, hard surfaced roads in
two-wheel drive high.
Operating Four-Wheel Drive with
a Spare or Mismatched tires
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could 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
four-wheel drive mode turned on.
Turn on a four-wheel drive mode
unless the vehicle is stationary.
Use a four-wheel drive mode on dry
pavement.
When driving with the full-size dissimilar
spare wheel and tire assembly, four-wheel
drive functionality can be limited,
especially when driving in a mechanically
locked four-wheel drive mode. You can
