Before Towing a Trailer
Practice turning, stopping andbacking up to get the feel of yourvehicle-trailer combination beforestarting on a trip. When turning,make wider turns so the trailerwheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than70 mph (113 km/h) during thefirst 500 mi (800 km).
•Do not make full-throttlestarts.
•Check your hitch, electricalconnections and trailer wheellug nuts thoroughly after youhave traveled 50 mi (80 km).
•When stopped in congested orheavy traffic during hotweather, place the gearshift inpark (P) to aid engine andtransmission cooling and tohelp air conditioningperformance.
•Switch off the speed controlwith heavy loads or in hillyterrain. The speed control mayturn off automatically whenyou are towing on long, steep
grades.
•Shift to a lower gear whendriving down a long or steephill. Do not apply the brakescontinuously, as they mayoverheat and become lesseffective.
•If your transmission is equippedwith a Grade Assist orTow/Haul feature, use thisfeature when towing. Thisprovides engine braking andhelps eliminate excessivetransmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance forstopping with a trailerattached. Anticipate stops andbrake gradually.
•Avoid parking on a grade.However, if you must park on agrade:
1.Turn the steering wheel topoint your vehicle tires awayfrom traffic flow.
2.Set your vehicle parking brake.
3.Place the automatictransmission in park (P).
4.Place wheel chocks in the frontand back of the trailer wheels.(Chocks not included withvehicle.)
