²The 4WD HIGH mode provides
four-wheel drive with full power
to both axles. It is only intended
for severe winter or off-road
conditions, such as deep snow
and ice (where no dry or wet
pavement remains uncovered),
and shallow sand.
²The 4WD LOW mode supplies
four-wheel drive with full power
to both axles and includes a
lower gear ratio for low-speed. It
is only intended for off-road
applications that require extra
power including deep sand,
steep grades and pulling a boat
and trailer out of the water.
The vehicle should not be
operated in 4WD HIGH and
4WD LOW on dry or merely wet
pavement. Doing so will
produce excessive noise,
increase tire wear and may
damage driveline components.
These modes are intended for
use only on consistently
slippery or loose surfaces.
If your vehicle is equipped with
4WD or AWD, a spare tire of a
different size than the road
tires should never be used.
Such a tire could result in
damage to driveline
components and make the
vehicle difficult to control.HIGH

CHANGING THE TIRES
If you get a flat tire while driving,
do not apply the brake heavily.
Instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.

spare tire that may be used as a
spare or a regular tire. The spare
tire is not equipped with wheel
trim. The wheel trim from the
original wheel/tire may be used on
the spare.
If your vehicle is equipped with
