Brake-Shift Interlock
WARNING: Do not drive yourvehicle until you verify that thestoplamps are working.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) whichmeans your vehicle can roll freely. Toavoid unwanted vehicle movement,always fully apply the parking brake priorto doing this procedure. Use wheelschocks if appropriate.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents moving thegearshift lever from park (P) when theignition is in the on position and the brakepedal is not pressed.
If you cannot move the gearshift lever outof park (P) position with the ignition in theon position and the brake pedal pressed,a malfunction may have occurred. It ispossible that a fuse has blown or yourvehicle’s brake lamps are not operatingproperly. See Fuse Specification Chart(page 71).
If the fuse is not blown and the brakelamps are working properly, the followingprocedure can allow you to move thegearshift lever from park (P):
1.Apply the parking brake. Turn key tothe lock position, and then remove thekey.
2.Disconnect the negative black batterycable from the battery.
3.Insert the key and turn to the offposition. Shift the transmission toneutral (N).
4.Reconnect the negative black batterycable to the battery.
5.Start the vehicle.
Note:See your authorized dealer as soonas possible if this procedure is used.
If Your Vehicle Gets Stuck In Mudor Snow
Note:Do not rock your vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires may occur, or theengine may overheat.

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.
Separate functioning brake systemsare required for safe control of towedvehicles and trailers weighing morethan 1500 lb (680 kg) when loaded.
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.
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.
