2-5. Driving information NOTICE n When installing a trailer hitch l Use only the position recommended by your Lexus dealer. Do not install the trailer hitch on the bumper; this may cause body damage. l Do not use axle-mounted hitches, as they can cause damage to the axle housing, wheel bearings, wheels or tires. n Brakes Lexus recommends trailers with brakes that conform to all applicable federal and state/provincial regulations. n Safety chain 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 the case that it becomes damaged or separated. For the correct safety chain installation procedure, ask your Lexus dealer. n Do not directly splice trailer lights Directly splicing trailer lights may damage your vehicle's electrical system and cause a malfunction. 186
