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.)

AUTOMATIC TRANSMISSION
FLUID CHECK
WARNING
The dipstick cap and surroundingcomponents may be hot; gloves arerecommended.
Note:Automatic transmission fluidexpands when warmed. To obtain anaccurate fluid check, drive the vehicle untilit is at normal operating temperature(approximately 20 miles [30 km]). If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be turned off for about 30 minutesto allow fluid to cool to normal operatingtemperature 150°F - 170°F (66°C - 77°C)before checking.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes.
Your transmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,(i.e., if the transmission slips or shiftsslowly) or if you notice some sign of fluidleakage. To check the fluid level:
1.Drive the vehicle 20 miles (30 km) oruntil it reaches normal operatingtemperature
2.Park the vehicle on a level surface andengage the parking brake
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.Latch the gearshift lever in P (Park)and leave the engine running.
5.Remove the dipstick, wiping it cleanwith a clean, dry lint free rag. Ifnecessary, refer to Under HoodOverview in this chapter for thelocation of the dipstick.
6.Install the dipstick making sure it is fullyseated in the filler tube.
7.Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature or ambient temperature.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Low fluid level
Do not drive the vehicle if there is noindication of fluid on the dipstick and theambient temperature is above 50°F(10°C).
Correct fluid level

Parking brake fluid
Note:Do not fill the parking brake throughthe vent plug (A) (located on top of thetransmission).
Check the parking brake fluid level only ifthere is visible signs of fluid leakage. Ifnecessary, fill the parking brake assemblyto the bottom of the filler plug hole (B)(located on the driver side of thetransmission). See Capacities andSpecifications (page 114).
POWER STEERING FLUID
CHECK
Note:The power steering cap has both acold and hot indicator on the dipstick.
1.Start the engine and let it run until itreaches normal operating temperature(the engine coolant temperature gaugeindicator will be near the center of thenormal area between H and C).
2.While the engine idles, turn the steeringwheel left and right several times.
3.Turn the engine off.
