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-

perature.

The restoration time may become

shorter when the coating is warmed by

applying warm water.

●

Deep scratches caused by keys, coins,

etc. cannot be restored.

●

Do not use wax that contain abrasives.

: The soft top roof does not have a self-

restoring coat.

■

Cleaning the areas with metal accents

Do not use baking soda (sodium bicarbon-

ate) and wax that contains abrasives.

■

Automatic car washes

Lexus does not recommend using an auto-

matic car wash.

●

Fold the mirrors before washing the vehi-

cle. Start washing from the front of the

vehicle. Make sure to extend the mirrors

before driving.
