COROLLA_U
7-1.Maintenance and care
Working from top to bottom,
liberally 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
waterproof coating deterio-
rates.
If water does not bead on a clean
surface, apply wax when the vehi-
cle body is cool.
■Automatic car washes
●Fold the mirrors before washing
the vehicle. 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
surface and harm your vehicle’s
paint.
●Vehicles with a rear spoiler: In cer-
tain automatic car washes, the rear spoiler may interfere with
machine operation. This may pre-
vent the vehicle from being
cleaned properly or result in dam-
age to the rear spoiler.
■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 (vehi-
cles with a smart key system)
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 pro-
cedures 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
washed. (Take care to ensure that
the key is not stolen.)
●Set the electronic key to bat-
tery-saving mode to disable the
smart key system. ( P.112)
■Aluminum wheels (if equipped)
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to observe the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the
wheels when they are hot, such
as after driving or parking in hot
weather
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
Cleaning and protect-
ing the vehicle exte-
rior
Perform cleaning in a man-
ner appropriate to each
component and its material.

Maintenance and care
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.
■Precautions regarding the
exhaust pipe
Exhaust gasses cause the
exhaust pipe to become quite hot.
When washing the vehicle, be
careful not to touch the pipe until it
has cooled sufficiently, as touch-
ing a hot exhaust pipe can cause
burns.
■Precaution regarding the rear
bumper with Blind Spot Moni-
tor (if equipped)
If the paint of the rear bumper is
chipped or scratched, the system
may malfunction. If this occurs,
consult your Toyota dealer.
NOTICE
■To prevent paint deteriora-
tion and corrosion on the
body and components (alumi-
num wheels, etc.)
●Wash the vehicle immediately in
the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on
the paint surface
• After driving in an area contami- nated with soot, oily smoke,
mine dust, iron powder or chem-
ical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint
surface
●If the paint is chipped or
scratched, have it repaired
immediately.
●To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity when storing 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 sur-
faces of the lights.
Wax may cause damage to the
lenses.
■To prevent damage to the
windshield 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 a high pressure
car wash
●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 manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
