S The trailer cargo load should be distributed so that the tongue load is 9 to 11% of the total trailer weight, not exceeding the maximum of 158 kg (350 lb.) for vehicles with towing kit or 90 kg (200 lb.) for vehicles without towing kit. Never load the trailer with more weight in the back than in the front. About 60% of the trailer load should be in the front half of the trailer and the remaining 40% in the rear. HITCHES S Use only a hitch which is recommended by the hitch manufacturer and conforms to the total trailer weight requirement. S Follow the directions supplied by the hitch manufacturer. Lubricate the hitch ball with a light coat of grease. S Toyota recommends removing the trailer hitch whenever you are not towing a trailer to reduce the possibility of additional damage caused by the hitch if your vehicle is struck from behind. After removing the hitch, seal any mounting holes in the vehicle body to prevent entry of pollutants such as exhaust fumes, dirt, water, etc. S 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. ! CAUTION S If the total trailer weight exceeds 453 kg (1000 lb.), trailer brakes are required. S Never tap into your vehicle's hydraulic system as it would lower its braking effectiveness. S 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. NOTICE Do not use axle-mounted hitches as they can cause damage to the axle housing, wheel bearings, wheels or tires. Also, never install a hitch which may interfere with the normal function of an Energy Absorbing Bumper, if so equipped. BRAKES AND SAFETY CHAINS S Toyota recommends trailers with brakes that conform to any applicable federal and state/provincial regulations. 132
