4A (4X4 AUTO)
- provides electronic control four-wheel drive with
power delivered to the front and rear wheels, as required, for
increased traction. This is appropriate for all on-road driving
conditions, including as dry road surfaces, but is especially useful on
wet pavement, snow, dirt, or gravel.
•
4H (4X4 HIGH)
- provides electronically locked four-wheel drive
power to front and rear wheels. This position is not recommended for
use on dry pavement. This position is only intended for severe winter
or off-road conditions, such as deep snow, ice or shallow sand.
Note:
Do not use 4H (4X4 HIGH) on dry, hard surfaced roads. Doing so can
produce excessive noise and increased tire wear. 4H (4X4 HIGH) is
only intended for consistently slippery or loose surfaces. Use of 4H
(4X4 HIGH) on these surfaces may produce some noise (such as
occasional clunks), but will not damage drive components.
•
4L (4X4 LOW)
- provides electronically locked four-wheel drive when
extra power at reduced speeds is required. This position is not
recommended for use on dry pavement. Use this position for off-road
low-speed operation or when extra power is required, such as climbing
steep grades, going through deep sand or pulling a boat out of the
water. 4L (4X4 LOW) will not engage while the vehicle is moving
above 3 mph (5 km/h); this is normal and should be no reason for
concern. Refer to
Shifting to/from 4L (4X4 LOW)
for proper
operation.
Note:
Do not use 4L (4X4 LOW) on dry, hard surfaced roads. Doing so
can produce excessive noise and increased tire wear. 4L (4X4 LOW) is
only intended for consistently slippery or loose surfaces. Use of 4L (4X4
LOW) on these surfaces may produce some noise (such as occasional
clunks), but will not damage drive components.
Note:
The AdvanceTrac system has the ability to take over control of
the transfer case clutch and disable it during driving maneuvers when
necessary.
Shifting between 2H (4X2) and 4A (4WD AUTO) or 4H (4X4 HIGH )
Move the control from 2H to 4A or 4H at a stop or while driving at any
forward speed. The message center may display
4X4 SHIFT IN
PROGRESS
during the system shift. The message center will then
display
4X4 AUTO
if 4A has been selected or
4X4 HIGH
if 4H is
selected. The message center will momentarily display
4X2
if 2H has
been selected.
Note:
Do not perform this operation if the rear wheels are slipping.
