'03 4Runner_U (L/O 0208) TIRES 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. The towing connector can be also connected to the trailer brake and trailer sub battery. BREAK-IN SCHEDULE D Ensure that your vehicle's tires are properly inflated. See page 318 in Section 7-2 and page 342 in Section 8 for instructions. D The trailer tires should be inflated to the pressure recommended by the trailer manufacturer in respect to the total trailer weight. TOWING LIGHTS CONNECTOR FOR TRAILER 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. 2003 4RUNNER from Aug.
