Toyota Sienna 2006 Operating Manual page 407

Note: The tire pressure warning sys-
tem on your vehicle will warn you
when one of your tires is significantly
under- inflated and when some com-
binations of your tires are significant-
ly under- inflated. However, there are
other combinations of significantly
under- inflated tires for which your
tire pressure warning system may not
warm you. These other combinations
are relatively common, accounting for
approximately half the instances in
which vehicles have significantly un-
der- inflated tires. For example, your
system may not warm you when both
tires on the same side or on the
same axle of your vehicle are signifi-
cantly under- inflated. It is particularly
important, therefore, for you to check
the tire pressure in all of your tires
regularly and maintain proper pres-
sure.

lowing:
1. Park the vehicle at a safe place and
apply the parking brake. Stop the en-
gine.

warning light comes on, push the reset

sure the warning light goes off.
4. Push and hold the reset switch until
the low tire pressure warning light
blinks three times.
Vehicles without vehicle stability control

driving at the speeds of 30 km/h (19 mph)
or over for about 8 hours total, when the
tire pressure warning system detects the
normal tire pressure.
