Maintaining the vehicle’s exterior
When washing the vehicle, be careful not to
touch the hood grilles, bezels in the radiator
grilles, or exhaust pipes and surrounding
area until they have cooled sufficiently, as
these components may cause burns.

• Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
• Do not flush water over or into the hood grilles (especially the arrowed portion in the
illustration).
• Do not flush water over or into the exhaust pipes and surrounding area or the bezels in
the radiator grilles until they have cooled sufficiently.
When using a high-pressure washer
• Do not aim the head of the nozzle at the hood grilles or radiator grilles. Doing so may
negatively affect the engine or cause a malfunction in the electric cooling fan motors that
may result in overheating.
• Do not allow the nozzles of the car wash to come within close proximity of the windows
or rear hatch.
Do not use automatic car washes as they may scratch the vehicle body and damage
the paint.

■Rear quarter glass
The rear quar ter glass is made from
polycarbonate resin. As this material
i s e a s i l y s c r a t c h e d c o m p a r e d t o
conventional glass, observe the following
procedure when cleaning:
1 Remove dust and dirt on the surface
with plenty of water.
2 Clean the surface using a mild soap or neu tral detergent.
3 Rinse it with adequate water.
When cleaning the rear quarter glass:
• Do not use wax, window cleaner or abrasive cleaner.
• Do not touch glass surface with anything hard or sharp.
• Do not use window scraper or deicer.
Do not attach stickers or apply water repellent coating to the rear quarter glass. Contact
with glue or other agents may cause the glass to become cloudy or blemished.
■
■Active rear wing
The active rear wing can be manually operated to allow excess water to be removed
after the vehicle is washed.
Manual operation is only possible when the vehicle is stationary with the ignition
switch in the “ON” position.
If the active rear wing is left in the raised
position, it will automatically retract when
the vehicle speed exceeds 16 MPH (25
km/h).
Before operating the switch to manually retract the active rear wing, make sure that the
area surrounding the wing is clear. Watch the active rear wing while operating the switch
to ensure that the operation proceeds smoothly.

■Waxing the vehicle
When water no longer clearly beads on the vehicle’s painted surfaces, apply a non-
abrasive wax.
Using waxes that contain abrasive compounds may damage the paint finish.
Do not use wax on vehicles painted “Matte Black”.

Special selection color “Matte Black”
The special selection color “Matte Black” overlays a black base with a clear coating.
This coating is made up of microscopic sillica particles mixed into a clear resin that
cancels out shine.
Applying excessive pressure to the painted surfaces may damage the resin coating
and result in an uneven or marred finish. To prevent this from occurring, rinse the
vehicle using a liberal amount of water and make sure to only use a soft sponge or
chamois when washing the vehicle.
Do not apply wax.
Doing so will leave a thin layer of wax on the clear resin coating that cannot be
evenly removed, causing the matte finish to appear blemished and uneven.
Quickly wipe away anything that adheres to the painted surfaces
Leaving alkaline liquids such as washer fluid on the paint surface may leave marks
or otherwise damage the paint. Quickly wipe away anything that adheres to the
painted surfaces.

■Maintaining the genuine leather areas
The leather areas throughout the interior are colored with water-soluble dyes and
feature a light pigmentation applied to the outer surface.
The leather is dyed to the desired hue from its original color of grey and then
imbedded with pigments to increase its durability. As a natural material, the leather is
supple and comfortable, breathable and moisture permeable.
■
■Daily maintenance
Remove dirt and dust using a vacuum cleaner and then wipe with a soft, dry cloth. For
cleaning, follow the procedure below:
1 Wipe off any excess dirt and dust with a soft cloth dampened with diluted detergent.
Use a diluted water solution of approximately 5% neutral wool detergent.
2 Wring out any excess water from the cloth and thoroughly wipe off all remaining
traces of detergent.
3 Wipe the surface with a dry, soft cloth to remove any remaining moisture. Allow
the leather to dry in a shaded and ventilated area.
Do not use any protective agents (coatings etc). Doing so may cause the instrument panel
to reflect onto the windshield, obstructing the front view.

■Maintaining the Alcantara® areas
Alcantara® is an artificial leather made from nonwoven micro fiber impregnated with
synthetic resins.
Durable, dirt proof and fire-resistant, this material offers suede-like softness with ample
breathability and moisture permeability.
■
■Daily maintenance
Brush the surfaces using a soft brush. Do not brush hard as doing so may cause
damage. For difficult to clean areas, follow the procedure below:
1 Wipe the surfaces clean with a soft cloth that has been dampened in cold or
lukewarm water and squeezed out.
2 Allow the artificial leather to dry in a shaded and ventilated area.

■Maintaining the CFRP (Carbon Fiber Reinforced
Plastics) areas
Some interior components such as the instrument panel and rear hatch are made
from the same CFRP material as the main body shell. These exposed components
feature a deep and three-dimensional presence with a special clear coating.
Additionally, panels underneath the windows have a matte coating to prevent glare
and reflections.
■
■Daily maintenance
For cleaning, follow the procedure below:
1 Wipe dirty surfaces with a dampened soft cloth or synthetic chamois.
2 Wipe away any remaining moisture with a soft, dry cloth.
• Do not rub the matte coated surfaces strongly as doing so may damage the surface or
cause it to shine.
• Do not use wax, polish or polishing cleaners. Especially use caution around the
instrument panel, as improper care may cause the instrument panel to reflect off of the
windshield, obstructing the driver's front view.
