Dinghy Towing Use the following procedure to tow your vehicle: 1. Shift the transmission to PARK (P). 2. Turn the engine off, but leave the ignition in ACCESSORY. 3. Firmly set the parking brake. 4. Securely attach the vehicle being towed to the tow vehicle. 6. Release the parking brake only after the vehicle being towed is firmly attached to the towing vehicle. You can use your vehicle's front mounted receiver with the proper accessories to tow it. See "Front Mounted Receiver" under If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-39. 7. Turn the ignition to ACCESSORY. 8. Disconnect the battery if you are going to tow for long distances or long periods of time. When towing your vehicle for extended periods of time, start your vehicle as often as possible to prevent battery drain. This should only be done when the tow vehicle is parked. {CAUTION: Shifting a full-time four-wheel-drive vehicle's transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. 5. Shift the transfer case to NEUTRAL (N). See Full-Time Four-Wheel Drive on page 2-36 for the proper procedure to select the NEUTRAL position for your vehicle. Dolly Towing Your vehicle cannot be dolly towed. If you must tow your vehicle behind another, use the dinghy towing procedure listed previously. Notice: Dolly towing your vehicle will damage drivetrain components. Do not dolly tow your vehicle. 4-52
