When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a slope. However, ifyou must park on a slope:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.
2.Set your vehicle parking brake.
3.Place the automatic transmission inpark (P) or manual transmission in alow gear.
4.Place wheel chocks in front and backof the trailer wheels. Chocks are notincluded with your vehicle.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Any time the rear axle submerges in water,replace the rear axle lubricant. Water maycontaminate the rear axle lubricant, whichis not a normal maintenance inspectionitem unless there is a possibility of a leakor other axle repair is required.
