ESSENTIAL TOWING CHECKS
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.
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. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the 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, turn signals and hazard lights areworking.
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
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mph(80 km/h).
•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.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.

At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is noneed to pull off the road. You can continueto drive your vehicle.
The air conditioning may turn on and offduring severe operating conditions toprotect the engine from overheating. Whenthe coolant temperature decreases to thenormal operating temperature, the airconditioning turns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.However, check the fluid level if thetransmission is not working properly, forexample if the transmission slips, shiftsslowly or if there are signs of fluid loss.
Replace the transmission fluid and filteron your vehicle at the specified serviceinterval. See Scheduled Maintenance(page 325).
Automatic transmission fluid expandswhen warmed. To check the fluid levelconsistently and accurately, do thefollowing:
1.Drive the vehicle until it reaches normaloperating temperature. This may takeup to 20 mi (30 km). Make sure thatthe transmission fluid temperaturegauge on the instrument cluster iswithin normal operating temperature196–215°F (91–102°C) beforechecking.
2.Make sure that your vehicle is on levelground.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.
4.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N) and leave the enginerunning.
5.Open the hood. See Opening andClosing the Hood (page 223).
6.Remove the dipstick and wipe it witha clean, lint-free cloth. See UnderHood Overview (page 225).
7.Replace the dipstick and remove itagain to check the fluid level.

8.If the fluid level is correct, replace thedipstick and make sure it is fully seated.
Note:If the fluid level is between themaximum and minimum marks, the fluidlevel is acceptable. Do not add fluid.
Transmission Fluid Level
Low Fluid Level
If the fluid level is at or below the minimummark, add fluid immediately. SeeAutomatic Transmission FluidCapacity and Specification (page 307).
Note:If there is no indication of fluid on thedipstick, have your vehicle checkedimmediately.
Correct Fluid Level
Make sure that the fluid level is betweenthe maximum and minimum marks.
High Fluid Level
Do not add fluid further than the maximummark. Fluid levels above the maximummark could cause shift or engagementconcerns and possible damage.
Note:An overheating condition can causehigh fluid levels.
Adding Transmission Fluid
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials couldaffect transmission operation and resultin damage to internal transmissioncomponents and could lead totransmission damage that the vehicleWarranty does not cover.
Use only recommended transmission fluidthat meets our specifications. SeeAutomatic Transmission FluidCapacity and Specification (page 307).
Note:Use of a non-approved automatictransmission fluid could cause internaltransmission component damage.
If necessary, add fluid in 8 fl oz (250 ml)increments through the filler tube until thelevel is correct.
If an overfill occurs, remove excess fluidand have your vehicle checked as soon aspossible.
