4X4 HIGH

USING FOUR-WHEEL DRIVE Note: For important information regarding safe operation of this type of vehicle, see General Information in the Wheels and Tires chapter. Note: Do not use SLIPPERY , DEEP CONDITIONS or SLOW CLIMB on dry, hard surfaced roads. Doing so produces excessive noise, increases tire wear and may damage drive components. The 4X4 system in these modes is only intended for consistently slippery or loose surfaces. 4X4 Indicator Lights 4X2

Continuously illuminates when a drive mode that uses 4H is selected.

WARNING Vehicles with a higher center of gravity (utility and four-wheel drive vehicles) handle differently than vehicles with a lower center of gravity (passenger cars). Avoid sharp turns, excessive speed and abrupt steering in these vehicles. Failure to drive cautiously increases the risk of losing control of your vehicle, vehicle rollover, personal injury and death. Note: The AdvanceTrac® with RSC® stability enhancement system can be turned off manually by pressing the AdvanceTrac button. See Using Traction Control (page 233). This disables the engine management feature, allowing the vehicle to maintain full power and enhanced momentum through the obstacle. Note: Drive modes should not be changed when the rear wheels are slipping. Your vehicle engages 4X4 modes based on the currently selected Drive Mode. See Drive Mode Control (page 287).
