Maintenance and care
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the switch is in “AUTO”, the wip-
ers may operate unexpectedly in

windshield where the raindrop
sensor is located is touched by
hand
●When a wet rag or similar is
held close to the raindrop sen-
sor
●If something bumps against the
windshield
●If you directly touch the raindrop
sensor body or if something
bumps into the raindrop sensor

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performance of each sys-
tem. If non-Toyota parts are used in
replacement or if a repair shop other
than a Toyota dealer performs
repairs, confirm the warranty cover-
age.
■Allow inspection and repairs to
be performed by a Toyota
dealer
●Toyota technicians are
well-trained specialists and are
kept up to date with the latest ser-
vice information. They are well
informed about the operation of all
systems on your vehicle.
●Keep a copy of the repair order. It
proves that the maintenance that
has been performed is under war-
ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.
