YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
■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 .
