TOWING A TRAILER
WARNING
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of your vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Note:Do not exceed the GVWR orthe GAWR specified on thecertification label. SeeRecommended Towing Weights(page 204).
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See Fuses(page 233).
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a ball mount with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page198).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.
