2022 TOYOTA COROLLA air conditioning

4127-1. Maintenance and care
NOTICE
●To prevent the wheels from corrod-
ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard
brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the
lenses.
■To prevent damage to the wind-
shield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver
side wiper arm upward first, and repeat for the passenger side. When
returning the wipers to their original
position, do so from the passenger side first.
■When using an automatic car wash (vehicles with rain-sensing
windshield wipers)
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”,
the wipers may operate and the wiper
blades may be damaged.
■When using a high pressure car
wash
●Vehicles with rear view monitor sys-
tem: When washing the vehicle, do
not spray the camera or its sur- rounding area directly with a high
pressure washer. Shock applied
from high pressure water may cause the device to not operate
normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-
tured cover), connectors or the fol-
lowing parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●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 c onditioning 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.

WA R N I N G
●Do not smoke, cause sparks or
expose an open flame to fuel or the
battery. Fuel and battery fumes are flammable.
●Be extremely cautious when work-ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●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 engine switch is OFF.
With the engine 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.426)
■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.
