Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following
circumstances:
●When changing the tire inflation pressure by changing traveling
speed or load weight, etc.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.
■How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (→P. 417)
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 START STOP” switch to IGNITION ON
mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly three times.
Wait for a few minutes with the IGNITION ON mode, and then
