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 the following. 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. 3RZ-FE engine 158 kg (350 lb.) 5VZ-FE engine 226 kg (500 lb.) HITCHES S Use only a weight carrying hitch designed for the total trailer weight. Toyota does not recommend using a weight distribution (load equalizing) hitch. S The hitch must be bolted securely to the vehicle frame and installed according to the hitch manufacturer's instructions. S The hitch ball and king pin should have a light coat of grease. S Toyota recommends removing the hitch when not towing to prevent injury and/or damage due to the hitch in event of a rear end collision. After removal of the hitch, seal the installation area to prevent entry of exhaust fumes and mud. 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 an axle-mounting hitch as it may cause damage to the axle housing, wheel bearings, wheels and or tires. BRAKES AND SAFETY CHAINS S Toyota recommends trailers with brakes that conform to any applicable federal and state/provincial regulations. 145
