• 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.

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

hitch, electrical connections and trailer wheel lug nuts.

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

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

• 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.

When backing down a ramp during boat launching or retrieval:

• do not allow the static water level to rise above the bottom edge of

the rear bumper.

• do not allow waves to break higher than 6 inches (15 cm) above the

bottom edge of the rear bumper.

Exceeding these limits may allow water to enter vehicle components:

• causing internal damage to the components.

• affecting driveability, emissions and reliability.

Replace the rear axle lubricant any time the axle has been submerged in

water. Rear axle lubricant quantities are not to be checked or changed

unless a leak is suspected or repair required.

RECREATIONAL TOWING

Follow these guidelines if you have a need for recreational (RV) towing.

An example of recreational towing would be towing your vehicle behind

a motorhome. These guidelines are designed to ensure that your

transmission is not damaged.

Note: Put your climate control system in recirculated air mode to

prevent exhaust fumes from entering the vehicle. Refer to the Climate

controls chapter for more information.
