When towing your vehicle, turn the ignition to OFF. To prevent your battery from draining while towing, remove the RDO BATT and CLSTR fuses from the instrument panel fuse block. Be sure to replace the fuse when you reach your destination. See "Fuses and Circuit Breakers" in the Index. Be sure to use the proper towing equipment designed for recreational vehicle towing. Follow the instructions for the towing equipment. Dolly Towing (Two-Wheel Drive Models Only) CAUTION: Shifting a four-wheel-drive vehicle's transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in Park (P), for an automatic transmission, or if your vehicle is in gear, for a manual transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. Your vehicle should not be towed with all four wheels on the ground. Your transmission has no provision for internal lubrication while being towed. To properly tow your vehicle, it should be placed on a platform trailer with all four wheels off the ground. Towing with all four wheels on the ground should be avoided. 4-43
