■
Self-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●
The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●
The restoration time differs depending on
the depth of the scratch and outside tem-
