TOWING A TRAILER - MACH 1
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).

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
•Consult your local motor vehicle lawsfor towing a trailer.
•See the instructions included withtowing accessories for the properinstallation and adjustmentspecifications.
•Service your vehicle more frequently ifyou tow a trailer. See your scheduledmaintenance information.
•If you use a rental trailer, follow theinstructions the rental agency givesyou.
You can find information on loadspecification terms found on the tire labeland Safety Compliance label as well asinstructions on calculating your vehicle'sload in the Load Carrying chapter. SeeLoad Limit (page 214).
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
Safety Chains
Note:Never attach safety chains to thebumper.
Always connect the safety chains to thehook retainers of your vehicle hitch.
To connect the safety chains, cross themunder the trailer tongue and allow enoughslack for turning tight corners. Do not allowthe chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, direction indicators and hazard lightsare working.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
