by sending a signal from a sensor that is
installed in each wheel when the tire
pressure is severely low relative to the
selected TPMS mode.
The tire pressure monitoring system will

speeds above 40 km/h (25 mph). Also,
this system may not react immediately to a

sharp object).

serious vehicle damage and ser-

while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver's side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on
the tire placard. Refer to "Tires

pressure monitoring system
