■ Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.
