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

to front and rear wheels. The “4X4 HIGH” 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威 with RSC, the

AdvanceTrac威 with RSC 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威 with RSC stability enhancement system can be turned

off manually by pressing the AdvanceTrac威 with RSC button (refer to

AdvanceTrac威 with Roll Stability Control (RSC) 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.
