Maintenance and care
 Remove dirt and dust using a
vacuum cleaner. Wipe dirty sur-
faces with a cloth dampened with
lukewarm water.
 If dirt cannot be removed, wipe it
off with a soft cloth dampened
with neutral detergent 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 foaming-
type cleaners available. Use a sponge or brush to apply the foam. Rub in over-lapping circles. Do not use water. Wipe
dirty surfaces and let them dry. Excel- lent 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 exces-
sive wear, fraying or cuts.
NOTICE
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-
cle body. Otherwise resin section, such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously 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.
●Do not wash the underside of the vehicle using a high pressure car
washer.
●Do not use the washer on the area
around the charging port lid. Water could get into the AC charging inlet and could damage the vehicle.

Maintenance and care
WARNING
■When working on the engine compartment
●Make sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and dam-age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience
discomfort, consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.482)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.
