Four-Wheel Drive (If Equipped)

PRINCIPLE OF OPERATION This system is a proactive system. It has the ability to anticipate wheel slip and transfer torque to the rear wheels before slip occurs. Even when wheel slip is not present, the system is continuouslymaking adjustments to the torque distribution, in an attempt to improve straight line and cornering behavior, both on and off road. The system automatically turns on every time you switch the ignition on. If any component requires maintenance, a message appears in the information display. USING FOUR-WHEEL DRIVE WARNING Vehicles with a higher center of gravity such as utility and four-wheel drive vehicles handle differently than vehicles with a lower center of gravity. 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, excessive speed and abrupt maneuvers in these vehicles. Failure to drive cautiously could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. The intelligent 4WD system continuously monitors vehicle conditions and automatically adjusts the power distribution between the front and rear wheels. It combines transparent all-surface operation with highly capable four-wheel drive.

The 4WD system is always active and requires no driver input. It is capable of handling all road conditions, including street and highway driving as well as off-road and winter driving. The driver can optimizemore 4WD control bymoving the terrainmanagement switch for the correct terrain. See UsingTerrainControl (page 199). Note: Awarningmessage will be displayed in the information display when an 4WD system fault is present See Information Messages (page 118). An 4WD systemfault will cause the 4WD system to default to front-wheel drive only mode. When this warning message is displayed, have your vehicle serviced at an authorized dealer Note: Awarningmessage will be displayed in the information display if the 4WD system has overheated See Information Messages (page 118). This condition may occur if the vehiclewas operated in extreme conditions with excessive wheel slip, such as deep sand. To resume normal 4WD function as soon as possible, stop the vehicle in a safe location and stop the engine for at least 10 minutes. After the engine has been restarted and the 4WD system has adequately cooled, the warning message will turn off and normal 4WD function will return. Do not use a spare tire of a different size other than the tire provided. If the mini-spare tire is installed, the4WDsystem may disable automatically and enter front-wheel drive only mode to protect driveline components. This condition will be indicated by a warning in the information display See Information Messages (page 118). If there is awarning message in the information display from using the spare tire, this indicator should turn off after reinstalling the repaired or replaced normal road tire and cycling the ignition off and on. It is recommended to
