Note: The information display may show
messages during 4WD operation. See
Information Messages (page 119).
Your 4X4 control is located in one of the
following locations:
• On the instrument panel.
• On the DRIVE MODE selection switch.
2H (4X2)
Delivers power to the rear wheels only. The
information display momentarily shows
2H when this mode is selected. This mode
is appropriate for normal on-road driving
on dry pavement and provides the best
fuel economy.
Note: 2H may turn on or off automatically
based on Drive Mode selection. See Drive
Control (page 251).
4A (4X4 AUTO)
Provides electronic controlled four-wheel
drive with power delivered to the front and
rear wheels, as required, for increased
traction. The Information Display will
display 4A when this mode is selected. The
system continuously monitors road
conditions, driver's input as well as other
vehicle sensors and optimizes the system's
behavior based on drive mode selection.
Note: 4A may turn on or off automatically
based on Drive Mode selection. See Drive
Control (page 251).
4H (4X4 HIGH)
Provides electronically locked four-wheel
drive power to front and rear wheels. The
information display will display 4H when
this mode is selected. This mode is not
recommended for use on dry pavement.
This mode is only intended for severe
winter or off-road conditions, such as deep
snow, ice or shallow sand.
Note: 4H may turn on or off automatically
based on Drive Mode selection. In certain
configurations, 4H-like functionality is
contained within specific off-road Drive
Modes even when the indicator lamp shows
4A. See Drive Control (page 251).
4L (4X4 LOW)
Provides electronically locked four-wheel
drive power to both the front and rear
wheels with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep grades, or pulling heavy
objects. 4L (4X4 low) will not engage while
your vehicle is moving above 3 mph
(5 km/h); this is normal and should be no
reason for concern. Refer to Shifting to or
from 4L (4X4 low) for proper operation.
Note: 4L may turn off automatically based
on Drive Mode selection. See Drive Control
(page 251).
Shifting Between 4WD System Modes
Note: Momentarily releasing the accelerator
pedal while a shift in progress message
displays improves engagement and
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
You can change between 2H to 4A or 4H
at a stop or while driving. The information
display may display a message indicating
a 4X4 shift is in progress and the LED light
for the selected mode flashes. Once the
shift is complete the information display
shows the system mode selected and the
LED light for the selected mode turns solid.
Shifting To or From 4L (4X4 LOW)
Note: 4L mode is not intended for use on
dry pavement.
