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.
Wring out any excess water
from the cloth and thoroughly
wipe off all remaining traces
of detergent.
 Wipe the surface with a dry,
soft cloth to remove any
remaining moisture. Allow the
leather to dry in a shaded and
ventilated area.
■Caring for leather areas
Toyota recommends cleaning the
interior of the vehicle at least twice a
year to maintain the quality of the
vehicle’s interior.
 Remove dirt and dust using a
vacuum cleaner.
 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.
NOTICE
■Cleaning the inside of the rear
window
●Do not use glass cleaner to
