2010 TOYOTA SIENNA speed

236 2-5. Driving information
CAUTION
■To avoid an accident
●Do not exceed 45 mph (72 km/h) or posted towing speed limit, whichever
is lower. As instability (swaying) of the towing vehicle-trailer combination
increases as speed increases, exceeding 45 mph (72 km/h) may cause
loss of control.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
● Avoid holding the brake pedal down too long or applying the brakes too
frequently. This could cause the brakes to overheat and result in reduced
braking efficiency.
