DRIVING TIPS Brakes and safety chains D Lexus recommends trailers with brakes that conform to any applicable federal and state/provincial regulations. D A safety chain must always be used between the towing vehicle and the trailer. Leave sufficient slack in the chain for turns. The chain should cross under the trailer tongue to prevent the tongue from dropping to the ground in case it becomes damaged or separated. For correct safety chain procedures, follow the hitch or trailer manufacturer's recommendations. Tires D Ensure that your vehicle's tires are properly inflated. Adjust the tire inflation pressure to the recommended cold tire inflation pressure indicated below: Tire inflation pressure, kPa (kgf/cm2 or bar, psi) P215/60R16 94V Front 200 (2.0, 29) Rear 200 (2.0, 29) P215/55R17 93V Front 220 (2.2, 32) Rear 220 (2.2, 32) D The trailer tires should be inflated to the pressure recommended by the trailer manufacturer in respect to the total trailer weight. CAUTION D If the total trailer weight exceeds 500 kg (1102 lb.), trailer brakes are required. D Never tap into your vehicle's hydraulic system as it will lower its braking effectiveness. 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 possible danger of the trailer wandering over into another lane. Trailer lights D 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. Break−in schedule D Lexus 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. 287
