2002 Toyota 4Runner Owners Manual - Page 218

'02 4Runner_U (L/O 0108) D Never tow a trailer without using a safety chain securely attached to both the trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of the trailer wandering over into another lane. TIRES BREAK-IN SCHEDULE D Toyota recommends that you do not tow a trailer with a new vehicle or a vehicle with any new power train component (engine, transmission, differential, wheel bearing, etc.) for the first 800 km (500 miles) of driving. MAINTENANCE D If you tow a trailer, your vehicle will require more frequent maintenance due to the additional load. For this information, please refer to the scheduled maintenance information in the "Scheduled Maintenance Guide" or "Owner's Manual Supplement". D Ensure that your vehicle's tires are properly inflated. See Section 7-2 for instructions. D The trailer tires should be inflated to the pressure recommended by the trailer manufacturer in respect to the total trailer weight. TRAILER LIGHTS D Your vehicle is equipped with a wire harness stored in the rear end under body. Some models are fitted with a socket for trailer lights under the rear bumper. Use either of them to connect and operate the trailer lights. However, the trailer lights must comply with federal, state/provincial and local regulations. See your local recreational vehicle dealer or rental agency for the correct type of wiring and relays for your trailer. Check for correct operation of the turn signals and stop lights each time you hitch up. Direct splicing may damage your vehicle's electrical system and cause a malfunction of your lights. 2002 MY 4RUNNER_U (OM35787U) D Retighten all fixing bolts of the towing ball and bracket after approximately 1000 km (600 miles) of trailer driving. 218
