7-1. Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■
Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■
Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
NOTICE
■
When using a high pressure
car wash
●
When washing the vehicle, do
not spray the camera or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●
Do not spray water directly on
the radar which is equipped
behind the emblem. Otherwise
it may cause the device to be
damaged.
●
Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●
Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●
Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.

of detergent, as they may dis-
color the vehicle interior or
cause streaks or damage to
painted surfaces:
• Areas other than the seats and
steering wheel: Organic sub-
stances such as benzene or
gasoline, alkaline or acidic solu-
tions, dye, and bleach
• Seats: Alkaline or acidic solu-
tions, such as thinner, benzene,
and alcohol
• Steering wheel: Organic sub-
stances, such as thinner, and
cleaner that contains alcohol

Remove dirt using a
water-dampened soft cloth or
synthetic chamois.
Wipe the surface with a dry,
soft cloth to remove any
remaining moisture.
■
Cleaning the areas with
satin-finish metal accents
The metal areas use a layer of real
metal for the surface. It is necessary
to clean them regularly. If dirty areas
are left uncleaned for long periods
of time, they may be difficult to
clean.
Remove dirt and dust using a
vacuum cleaner.
Wipe off any excess dirt and
dust with a soft cloth damp-
ened with diluted detergent.
Use a diluted water solution of
approximately 5% neutral wool
detergent.
