Full-Time Four-Wheel
Drive
Full-Time Four-Wheel Drive sends
engine power to all four wheels
for extra traction. To get the most
out of Full-Time Four-Wheel Drive,
you must be familiar with its
operation.
Transfer Case Buttons
The transfer case buttons are
located to the right of the instrument
panel cluster. Use these switches to
shift into and out of the different
Full-Time Four-Wheel Drive modes.4
m(Four-Wheel High):This
setting is used for driving in most
street and highway situations.
You can also use this setting for
light or variable off-road conditions.
N (Neutral):Shift the transfer
case to Neutral only when towing
the vehicle. SeeRecreational
Vehicle Towing on page 4-40or
Towing Your Vehicle on page 4-40
for more information.
Notice:Driving on pavement in
Four-Wheel High Lock or Four
Wheel Low Lock for extended
periods may cause premature
wear on the vehicle powertrain
and tires. Do not drive in
Four-Wheel High Lock or
Four-Wheel Low Lock on
pavement for extended periods.
4
mQ(Four-Wheel-High Lock):
Use this setting when you need
extra traction in most off-road
situations such as sand, mud, snow
or level, rocky trails.Notice:Operating the vehicle in
Four-Wheel-Low Lock above
30 mph (48 km/h) for any
extended period of time could
cause damage to the transfer
case. Do not operate the vehicle
in Four-Wheel-Low Lock above
30 mph (48 km/h) for extended
periods.
4
nQ(Four-Wheel-Low Lock):
This setting delivers extra torque to
all four wheels and is used for
extreme off-road conditions.
If the vehicle has locking axles,
they can be locked for additional
traction in extreme off-road
situations. SeeLocking Rear Axle
on page 4-8andLocking Front Axle
on page 4-9.
Indicator lights in the buttons show
which setting the transfer case
is in. The indicator lights will come

fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
The cruise control disengages, if the
vehicle has the Traction Control
System (TCS) and it begins to limit
wheel spin. SeeTraction Control
