TOWING A TRAILER
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Towing trailers beyondthe maximum recommended grosstrailer weight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
Note:There may be electrical itemssuch as fuses or relays that can affecttrailer towing operation. See Fuses(page 277).
The load capacity of your vehicle isdesignated by weight not volume. Youmay not necessarily be able to use allavailable space when loading yourvehicle or trailer.
Towing a trailer places extra load on theengine, transmission, axle, brakes, tires,and suspension. Inspect thesecomponents before, during and aftertowing.
Load Placement
To help minimize how trailer movementaffects the vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items in the centerof the left and right side trailer tires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight.
•Select a ball mount with the correctrise or drop. When both the loadedvehicle and trailer are connected, thetrailer frame should be level, orslightly angled down toward thevehicle, when viewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located in theLoad Carrying chapter. See Load Limit(page 248).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.
