Maintenance
WARNING
Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward
speed.

NOTICE
• Water washing in the engine
compartment including high pressure
water washing may cause the failure
of electrical circuits located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle
(if equipped)
Automatic car wash which uses
rotating brushes should not be used
as this can damage the surface of your
vehicle. A steam cleaner which washes
the vehicle surface at high temperature
may result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber towel
or sponge) when washing your vehicle
and dry with a microfiber towel. When
you hand wash your vehicle, you should
not use a cleaner that finishes with
wax. If the vehicle surface is too dirty
(sand, dirt, dust, contaminant, etc.),
clean the surface with water before
washing the car.
Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to maintain
its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.
