■Low Fuel Warning Light
The light illumination timing may vary because fuel inside the fuel tank moves
around according to the driving conditions and the vehicle post ure.
■ Seat Belt Warning Light
●The warning light flashes for about 6 seconds if the driver’s s eat belt is not
fastened when the ignition is switched ON.
● To allow the front passenger occupant classification sensor to function prop-
erly, do not place and sit on an additional seat cushion on the front passen-
ger’s seat. The sensor may not function properly because the ad ditional
seat cushion could cause sensor interference.
● If a small child is seated on the front passenger’s seat, the warning light may
not operate.
■ Tire Pressure Monitoring System Warning Light
●
Perform tire pressure adjustment when 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 adju sting the tire
pressures. When pressure is adjusted on hot tires to the cold i nflation
pressure, the TPMS warning light/beep may turn on after the tir es cool
and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from the tire air pres-
sure dropping due to cold ambient temperature will remain illum inated
even if the ambient t emperature rises. In this case, it will also be neces-
sary to adjust the tire air pressures. If the TPMS warning ligh t illuminates
due to a drop in tire air pressure, make sure to check and adju st 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 s idewall. Put
a few drops of water in the valve stem to see if it bubbles ind icating a
bad valve. Leaks need to be addressed by more than simply reinf lating
the tire as leaks are dangerous - take it to your Toyota dealer .

If Trouble Arises
WARNING
■If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, decr ease
vehicle speed immediately and avoid sudden maneuvering and
braking
If the tire pressure monitoring system warning light illuminate s or
flashes, or the tire pressure war ning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden mane uvering
or braking. Vehicle drivability co uld worsen and result 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 determ ine if you
have enough air to proceed to a place where air may be added an d the
system monitored again by your Toyota dealer or a tire repair s tation.
■Do not ignore the TPMS Warning Light
Ignoring the TPMS warning light is dangerous, even if you know why it
is illuminated. Have the problem taken care of as soon as possi ble
before it develops into a more serious situation that could lea d to tire
failure and a dangerous accident.
