6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
Wipe away any water.
Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■Black stainless steel window moldings (F
SPORT models)
The stainless steel window moldings are
made of black oxide coated stainless steel.
When cleaning the vehicle, do not scrub the
moldings with an abrasive cleaner as their
finish may be damaged or the color may
change.
■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 contains abrasives.
■Automatic car washes
●Fold the mirrors befo re washing the vehi-
cle. Start washing from the front of the
vehicle. Make sure to extend the mirrors
before driving.
●Brushes used in automatic car washes
may scratch the vehicle body and dam-
age the paint.
■High pressure car washes
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■When using a car wash
If the door handle becomes wet while the
electronic key is within the effective range,
the door may lock and unlock repeatedly. In
that case, follow the following correction
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the
vehicle is being wash ed. (Take care to
ensure that the key is not stolen.)
●Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.93)
■Aluminum wheels
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-
