WARNING: Your vehicle isnot approved for trailer towing.Never tow a trailer with yourvehicle.
TOWING A TRAILER
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
Note:There may be electricalitems such as fuses or relays thatcan affect trailer towing operation.See Fuses (page 246).
The load capacity of your vehicleis designated by weight notvolume. You may not necessarilybe able to use all available spacewhen loading your vehicle ortrailer.
Towing a trailer places extra loadon the engine, transmission, axle,brakes, tires, and suspension.Inspect these components before,during and after towing.
Load Placement
To help minimize how trailermovement affects the vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest items in thecenter of the left and right sidetrailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to go
above 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 thevehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibration
or shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in the Load Carryingchapter. See Load Limit (page214).
