Tire Pressure Monitoring System (TPMS)
U.S. model
To see the inflation pressures of all
four tires, press the SEL/RESET
button on the steering wheel. The
display changes as shown above.
268
Canadian model
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator in the instrument
panel to come on. If this happens,
you will see which tire is losing
pressure on the multi-information
display along with a ''CHECK TIRE
PRESSURE'' message.
