Connection of trailer lights to your vehicle's electrical system requires modifications to the vehicle's lighting circuit to increase its capacity and accommodate wiring changes. To ensure the trailer lights are connected properly, please consult your SUBARU dealer. Check for proper operation of the turn signals, the brake lights and parking lights each time you hitch up. n Tires WARNING Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load. Use of the temporary spare tire when towing can result in failure of the spare tire and/or less stability of the vehicle. Make sure that all the tires on your vehicle are properly inflated. OUTBACK: The recommended cold tire pressure under trailer towing conditions is indicated on the tire placard located under the door striker on the driver's side. Adjust the rear tire pressure to the recommended pressure shown on the tire placard when the tires are cold. Normal pressure should be maintained in the front tires. Other models: It is recommended to inflate the rear tires to 3 psi (20 kPa, 0.2 kg/cm2) above their normal operating pressure when the tires are cold. Normal pressure should be maintained in the front tires. Trailer tire condition, size, load rating and proper inflation pressure should be in accordance with the trailer manufacturer's specifications. In the event your vehicle gets a flat tire when towing a trailer, ask a commercial road service to repair the flat tire. If you carry a regular size spare tire in your vehicle or trailer as a precaution against getting a flat tire, be sure that the spare tire is firmly secured. 8-36
