If Trouble Arises
■Tire Pressure Monitoring System Warning Light
●
Perform tire pressure adjustment wh en the tires are cold. Tire pressure
will vary according to the tire temperature, therefore let the vehicle stand
for 1 hour or only drive it 1 mile (1.6 km) or less before adjusting the tire
pressures. When pressure is adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may turn on after the tires cool
and pressure drops below specification.
Also, an illuminated TPMS warning ligh t, resulting from the tire air pres-
sure dropping due to cold ambient temperature will remain illuminated
even if the ambient temper ature rises. In this case, it will also be neces-
sary to adjust the tire air pressures. If the TPMS warning light illuminates
due to a drop in tire air pressure, make sure to check and adjust the tire
air pressures.
●Tires lose air naturally over time and the TPMS cannot tell if the tires are
getting too soft over time or you have a flat. However, when you find one
low tire in a set of four-that is an indication of trouble; you should have
someone drive the vehicle slowly forward so you can inspect any low
tire for cuts and any metal objects sticking through tread or sidewall. Put
a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be address ed by more than simply reinflating
the tire as leaks are dangerous - take it to your Toyota dealer.
WARNING
■If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, decrease
vehicle speed immediately and avoid sudden maneuvering and
braking
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden maneuvering
or braking. Vehicle driv ability could worsen and re sult in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position
where you can check the visual condition of the tire and determine if you
have enough air to proceed to a place where air may be added and the
system monitored again by your Toyota dealer or a tire repair station.
■Do not ignore the TPMS Warning Light
Ignoring the TPMS warning light is da ngerous, even if you know why it
is illuminated. Have th e problem taken care of as soon as possible
before it develops into a more serious situation that could lead to tire
failure and a dangerous accident.

or it is placed in a poor signal reception area.
The warning beep sound will be heard for about 3 seconds when
there is any abnormality in tire inflation pressures (→P. 218).
