Your vehicle has also been equipped
with a TPMS malfunction telltale to
indicate when the system is not oper-
ating properly. When the malfunction
telltale is illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS mal-
function may occur for a variety of
reasons, including the installation of
incompatible replacement tires on the
vehicle. Always check the TPMS mal-
function telltale after replacing one or
more tires on your vehicle to ensure
that the replacement tires are compat-
ible with the TPMS.NOTICE
Do not use liquid sealants for a flat
tire as tire pressure sensors will be
damaged.
When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected
by the installation or removal of
tires.
The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
When the tires must be replaced,
replace the grommets for tire pres-
sure sensors as well.
Tire inflation pressure should be
adjusted for all 5 tires (including a
spare tire).
Warning tends to turn on when
driving at lower outside tempera-
ture, such as in winter, because tire
inflation pressure will be decreased
due to the low temperature. In this
case, after adjustment and initializa-
tion, leave the ignition on for about
20 minutes and increase the tire
inflation pressure by 20 to 30 kPa.
