• Consider turning overdrive off (4–speed transmissions) or using the

tow/haul feature (5–speed transmissions) to eliminate excessive

shifting and assist in transmission cooling. For additional information,

refer to Automatic transmission operation in the Driving chapter.

• Allow more distance for stopping with a trailer attached; anticipate

stops and brake gradually.

When descending long, steep downhill grades, always use a lower gear to

provide engine braking to save wear on brakes. Use D (Overdrive OFF)

on moderately steep hills, 2 (Second) on steep hills, and 1 (First) on

very steep hills. Do not apply your brakes continuously, as they

may overheat and become less effective.

Servicing after towing

If you tow a trailer for long distances, your vehicle will require more

frequent service intervals. Refer to Special operating conditions in the

Scheduled Maintenance Guide chapter.

Trailer towing tips

• Practice turning, stopping and backing-up before starting on a trip to

get the feel of the vehicle-trailer combination. When turning, make

wider turns so the trailer wheels will clear curbs and other obstacles.

• To aid in engine/transmission cooling and A/C efficiency during hot

weather while stopped in traffic, place the gearshift lever in P (Park).

• After you have traveled 50 miles (80 km), thoroughly check your

hitch, electrical connections and trailer wheel lug nuts.

• If you will be towing a trailer frequently in hot weather, hilly

conditions, at GCWR, or any combination of these factors, consider

refilling your rear axle with synthetic gear lube if not already so

equipped. Refer to the Maintenance and Specifications chapter for

the lubricant specification. Remember that regardless of the rear axle

lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a

new vehicle, and that the first 500 miles (800 km) of towing be done

at no faster than 70 mph (113 km/h) with no full throttle starts.

• Do not tow a trailer for the first 500 miles (800 km) after changing

the rear axle lube.

• Vehicles with trailers should not be parked on a grade. If you must

park on a grade, place wheel chocks under the trailer’s wheels.

Launching or retrieving a boat

Disconnect the wiring to the trailer before backing the trailer

into the water. Reconnect the wiring to the trailer after the

trailer is removed from the water.
