Towing

Your vehicle may be equipped with a temporary or conventional spare tire. A temporary spare tire is different in size (diameter or width), tread-type (All-Season or All-Terrain) or is from a different manufacturer than the road tires on your vehicle. Consult information on the tire label or Safety Compliance label for limitations when using. Launching or Retrieving a Boat or Personal Watercraft (PWC) Note: Disconnect the wiring to the trailer before backing the trailer into the water. Note: Reconnect the wiring to the trailer after removing the trailer from the water. When backing down a ramp during boat launching or retrieval: • Do not allow the static water level to rise above the bottom edge of the rear bumper. • Do not allow waves to break higher than 6 inches (15 centimeters) above the bottom edge of the rear bumper.

• Shift to a lower gear when driving down a long or steep hill. Do not apply the brakes continuously, as they may overheat and become less effective. • If your transmission is equipped with a Grade Assist or Tow/Haul feature, use this feature when towing. This provides engine braking and helps eliminate excessive transmission shifting for optimum fuel economy and transmission cooling. • If your vehicle is equipped with AdvanceTrac with RSC, this system may turn on during typical cornering maneuvers with a heavily loaded trailer. This is normal. Turning the corner at a slower speed while towing may reduce this tendency. • If your vehicle is equipped with Continuous Controlled Damping Suspension (CCD Suspension), you can select NORMAL or SPORT drive control modes for better experience while towing a trailer. See Information Displays (page 122).

• If you are towing a trailer frequently in hot weather, hilly conditions, at the gross combined weight rating (or any combination of these factors), consider refilling your rear axle with synthetic gear lubricant (if the axle is not already filled with it). See Capacities and Specifications (page 422). • Allow more distance for stopping with a trailer attached. Anticipate stops and brake gradually. • Avoid parking on a grade. However, if you must park on a grade: 1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake. 3. Place the transmission in park (P). 4. Place wheel chocks in the front and back of the trailer wheels. Note: Chocks are not included with your vehicle.
