How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the engine switch to off. Initialization cannot be performed while the vehicle is moved.
Adjust the tire inflation pressure to th e specified cold tire inflation pressure
level. (  P. 569)Make sure to adjust the tire pressure to the specified cold tire inflation pressure
level. The tire pressure warning system will 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 displa y while the tire
pressure warning system determines
the position of each tire.
When position of each tire is determined, the inflation pressure of each tire will be
displayed on the mult i-information display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for approx-
imately 10 minutes. When initialization is comple te, 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.
