4H (4X4 HIGH) provides mechanically locked four-wheel drive power

to front and rear wheels. The “4X4” light will illuminate in the
instrument cluster when this position is selected. 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.

4L (4X4 LOW) provides mechanically locked four-wheel drive when

extra power at reduced speeds is required. The “4X4 LOW” light will
illuminate in the instrument cluster when this position is selected.
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.

Note: If your vehicle is equipped with AdvanceTrac

௢, the

AdvanceTrac

௢ system will automatically turn off the stability

enhancement feature when you shift the Control Trac A4WD system into
4L (4X4 LOW). The brake traction enhancement feature will still be
enabled.

The AdvanceTrac

௢ stability enhancement system can be turned off

manually by pressing the AdvanceTrac

௢ button (refer to AdvanceTrac

Stability Enhancement System in this chapter) while operating in 2H,
A4WD or 4H while driving in deep sand, very deep snow or more
strenuous off-road maneuvers. This will disable the engine management
feature, allowing the vehicle to maintain full power and enhanced
momentum through the obstacle.

Utility and four-wheel drive vehicles are not designed for
cornering at speeds as high as passenger cars any more than

low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.

Note: The Control Trac selector knob should not be changed while the
rear wheels are slipping.
