D If the total trailer weight exceeds 453 kg (1000 lb.), trailer brakes are required. D Never tap into your vehicle's hydraulic system as it would lower its braking effectiveness. CY30008 D The trailer tires should be inflated to the pressure recommended by the trailer manufacturer in respect to the total trailer weight. 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. SERVICE CONNECTOR BRAKE CONTROLLER FOR TOWING Your vehicle is equipped with a service connector for the towing brake controller as shown. Link the connector to the towing brake controller via the sub wire harness stored in the glove box. The detailed explanation of the sub wire harness circuit is packed together with the sub wire harness. Be sure to position the towing brake controller where it does not prevent the driver from operating the pedal. Toyota recommends that the sub wire harness be stored in the glove box when it is not in use. 2007 4Runner from Aug. '06 Prod. (OM35866U) 367
