Trailer Brakes
WARNING
Do not connect a trailer's hydraulicbrake system directly to yourvehicle's brake system. Your vehiclemay not have enough braking power andyour chances of having a collision greatlyincrease.
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.
Separate functioning brake systemsare required for safe control of towedvehicles and trailers weighing morethan 1500 pounds (680 kilograms)when loaded.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
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.
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 thegearshift in park (P) to aid engine andtransmission cooling and to help airconditioning performance.
•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 grade. However, ifyou must park on a grade:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase theengine temperature and cause theengine to shut down completely.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 13).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine will continue to operatewith limited power for a short time.
If the engine temperature continues to rise,the fuel supply to the engine will reduce.The air conditioning will switch off and theengine cooling fan will operate continually.
1.Reduce your speed gradually and stopyour vehicle as soon as it is safe to doso.
2.Switch the engine off immediately toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 84).
5.Have your vehicle checked by anauthorized dealer as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
