• 4A (Two-speed automatic 4WD) - 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 (Two-speed automatic 4WD) 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.

Note: Some noise may be heard as the system shifts or engages; this is

normal.

Note: 4X4 high mode is not intended for use on dry pavement.
