The tire pressure warning system may be disabled in the following condi-
tions:

● If electronic devices or facilities using similar radio wave frequencies
are nearby.

● If a window tint that affects the radio wave signals is installed.
● If there is a lot of snow or ice on the vehicle, in particular around the
