Toyota Sienna 2006 Operating Manual page 668

The following instructions for
checking tire inflation pressure
should be observed:
" The
pressure should
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading.
" Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
" Take special care when adding
air to the compact spare tire.
The smaller tire size can gain
pressure very quickly. Add com-
pressed air in small quantities and
check the pressure often until it
reaches the specified pressure.

" Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.

" Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.
