Towing

Note: Exceeding this limitation may significantly reduce the performance of your towing vehicle. Selecting a trailer with a low aerodynamic drag and rounded front design helps optimize performance and fuel economy. Note: For high altitude operation, reduce the gross combined weight by 2% per 1,000 ft (300 m) starting at the 1,000 ft (300 m) elevation point. Note: Certain states require electric trailer brakes for trailers over a specified weight. Be sure to check state regulations for this specified weight. The maximum trailer weights listed may be limited to this specified weight, as the vehicle’s electrical system may not include the wiring connector needed to activate electric trailer brakes. Your vehicle may tow a trailer provided the maximum trailer weight is less than or equal to the maximum trailer weight listed for your vehicle configuration on the following chart.

To calculate the maximum loaded trailer weight for your vehicle: 1. Start with the gross combined weight rating for your vehicle model and axle ratio. See the following chart. 2. Subtract all of the following that apply to your vehicle: • Vehicle curb weight • Hitch hardware weight, such as a draw bar, ball, locks or weight distributing • Driver weight • Passenger(s) weight • Payload, cargo and luggage weight • Aftermarket equipment weight. 3. This equals the maximum loaded trailer weight for this combination. Note: The trailer tongue load figures into the payload for your vehicle. Reduce the total payload by the final trailer tongue weight.

This feature applies your vehicle brakes at individual wheels and, if necessary, reduces engine power. If the trailer begins to sway, the stability control light flashes and the message TRAILER SWAY REDUCE SPEED appears in the information display. The first thing to do is slow your vehicle down, then pull safely to the side of the road and check for proper tongue load and trailer load distribution. See Load Carrying (page 289). Note: Do not exceed the trailer weight for your vehicle configuration listed in the chart below. Note: Make sure to take into consideration trailer frontal area. Do not exceed 36.5 feet² (3.39 meters²) if your vehicle is equipped with the standard towing package, or 60 feet² (5.57 meters²) if your vehicle is equipped with the optional heavy duty package.
