tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the

Illustrations in this manual are simpli-
fied for explanation and may not repre-
sent the actual vehicle.
Glossiness of a surface is seen by the
human eyes by a difference in the
amount of light that reflects off the sur-
face.
A surface painted with normal clear
coat is flat and smooth. As the amount
of light that reflects off the surface is
large, the vehicle body will appear
glossy.
A surface painted with a matte clear
coat is slightly uneven due to the added
matting agent. As the light shining on
an uneven surface is diffused signifi-
cantly, the amount of light reflected is
small, making the vehicle body look not
glossy, with a unique texture.

Maintenance and care
●Rain water, sea water, and other liquids
that may cause water stains
●Sand, pollen, volcanic ash, and other par-
ticulate matter
●Dead insects, bird droppings, etc.
●Sap, leaves, flowers, etc.
●Mud, snow, anti-freezing agents, and
other road debris
●Gasoline, engine oil, asphalt, and other
oily materials
■Do not apply a coating to the vehicle
Do not apply a coating to the vehicle body,
as it will form a film over the painted sur-
faces, filling the matte clear coat surface,
making it more flat. As a result, it will
become more glossy, possibly permanently
losing its matte properties.
Take care in order to not damage the
painted surfaces.
When minor damage occurs to a vehi-
cle with a normal clear coat, it can be
repaired by polishing it or using touch
up paint. In contrast, a matte clear coat cannot be repaired using these meth-
ods.
If these methods are used the uneven-
ness of the matte clear coat may be
removed or filled in. In either case, the
surface will become more flat, making
