The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer/retailer for advice and information about towing a trailer with the vehicle. To identify the trailering capacity of the vehicle, read the information in "Weight of the Trailer" that appears later in this section.
