04 SIENNA_U (L/O 0408) D Because stopping distance may be increased, vehicle- to- vehicle distance should be increased when towing a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and trailer length between you and the vehicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control. This is especially true on wet or slippery surfaces. D Crosswinds and rough roads will adversely affect handling of your vehicle and trailer, causing sway. Pay attention to the rear from time to time to prepare yourself for being passed by large trucks or buses, which may cause your vehicle and trailer to sway. If swaying happens, firmly grip the steering wheel and reduce speed immediately but gradually. Never increase speed. Steer straight ahead. If you make no extreme correction with the steering or brakes, the vehicle and trailer will stabilize. D Because of the added load of the trailer, your vehicle's engine may overheat on hot days (at temperatures over 30_C [85_F]) when going up a long or steep grade with a trailer. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull off the road and stop in a safe spot. Refer to "If your vehicle overheats" on page 410 in Section 4. D Avoid jerky starts or sudden acceleration. D Always place wheel blocks under both the vehicle and trailer wheels when parking. Apply the parking brake firmly. Put the transmission in "P". Avoid parking on a slope with a trailer, but if it cannot be avoided, do so only after performing the following: 1. Apply the brakes and hold. 2. Have someone place wheel blocks under both the vehicle and trailer wheels. 3. When the wheel blocks are in place, release your brakes slowly until the blocks absorb the load. 4. Apply the parking brake firmly. 5. Shift into "P" and turn off the engine. D Avoid jerky steering and sharp turns. The trailer could hit your vehicle in a tight turn. Slow down before making a turn to avoid the necessity of sudden braking. D Be careful when passing other vehicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer and be sure you have plenty of room before changing lanes. D Remember that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Therefore, compensate for this by making a larger than normal turning radius with your vehicle. D In order to maintain engine braking efficiency, do not place the transmission in "D". 402 2004 SIENNA from Aug. '04 Prod. (OM45422U)
