■How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the engine switch to OFF.
Initialization cannot be performe d while the vehicle is moved.
Adjust the tire inflation pressure to the specified cold tire inflation pressure
level. (P. 5 6 9 )
Make sure to adjust the tire pressure to the specified cold tire inflation pressure
level. The tire pressure warning system w ill operate based on this pressure level.
Turn the engine switch to IGNITION ON mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
“--” will be displayed for inflation
pressure of each tire on the multi-
information display while the tire
pressure warning system determines
the position on the multi-information
display.
When position of each tire is determined, the inflation pressure of each tire will be
displayed on the multi-information display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for approx-
imately 10 minutes.
When initialization is complete , the inflation pressure of each tire will be displayed
on the multi-information display.
Initialization will take long er than approximately 10 minutes if the vehicle is
stopped for a long time, su ch as at traffic signals.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique ID
code. When replacing a tire pressure warning valve and transmitter, it is nec-
essary to register the ID code of tire pressure warning valve and transmitter.

Maintenance and care
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air- port or other facility th at generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
If tire position information is not correctl y displayed due to the radio wave conditions,
the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carry ing out initialization or tire inflation pres-
sure adjustment.
●If you have accidentally turned the engine swit ch off during initialization, it is not neces-
sary to press the reset switch again as init ialization will restart automatically when the
engine switch has been turned to IG NITION ON mode for the next time.
●If you accidentally press the reset switch when initialization is not necessary, adjust the
tire inflation pressure to the specified level when the tires are co ld, and conduct initial-
ization again.
●While the position of each tire is being de termined and the inflation pressures are not
being displayed on the mu lti-information display, if the in flation pressure of a tire drops,
the tire pressure warning light will come on.
