UTILITY OVERDRIVE OFF SWITCH • The parking brake must be firmly engaged and the wheels chocked during driveshaft removal and installation. The parking brake must remain engaged unless the vehicle is securely and properly connected to the tow vehicle, or the driveshaft is completely reinstalled. See your authorized dealer for proper driveshaft removal and reinstallation procedures, including flange orientation/alignment, use of thread-locking compound, proper bolt torque specifications, etc. Towing - Four-Wheel Drive Models • Overdrive can be locked out by pressing the O/D OFF switch located on the center console. An indicator light in the instrument cluster will illuminate to show that the switch has been activated. Pressing the switch a second time restores the Overdrive function. • When frequent transmission shifting occurs while using Overdrive, such as when operating the vehicle under heavy load conditions (for example, in hilly terrain, strong head winds, or trailer towing), turning off overdrive will improve performance and extend transmission life by reducing excessive shifting and heat buildup. NOTE: The transfer case must be shifted into N (Neutral), automatic transmission must be shifted into PARK, and manual transmission must be placed in gear (NOT in NEUTRAL) for recreational towing. • Bring the vehicle to a complete stop, turn off the engine and press and hold the brake pedal. • Shift the automatic transmission into NEUTRAL or depress the clutch pedal on a manual transmission. • Shift the transfer case lever into N (Neutral). • Start the engine and shift the transmission into REVERSE. • Release the brake pedal (and clutch pedal on manual transmissions) for five seconds and ensure that there is no vehicle movement. • Repeat the previous step with automatic transmission in DRIVE or manual transmission in first gear. • Turn OFF the engine and leave the ignition switch in the unlocked OFF position. • Firmly apply the parking brake and shift the transmission into PARK or place manual transmission in gear (NOT in Neutral). RECREATIONAL TOWING (BEHIND MOTORHOME) Towing - Two-Wheel Drive Models • Recreational towing with all four wheels on the ground is allowed ONLY if the rear driveshaft is removed. See your authorized dealer or refer to the Service Manual. Towing with the rear wheels on the ground while the driveshaft is connected can result in severe transmission damage. 52
