Start the hybrid system and make sure that the go to service warn-
ing light (vehicles with monochrome display) or “Maintenance
required for Traction battery cooling parts. See owner’s manual.” on
the multi-information display (vehicles with color display) turns off.
Vehicles with monochrome display
It may take up to 20 minutes for the light to turns off, after the hybrid
system is started. If the light does not turns off, even though the fil-
ter is clean, consult any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
Vehicles with color display
It may take up to 20 minutes for the message to turns off, after the
hybrid system is started. If the message does not turns off, even
though the filter is clean, consult any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
■ Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.

4247-1. Maintenance and care
YARIS_HV_OM_Europe_OM52J66E
■ Maintenance for air intake vent for cooling the hybrid battery (traction
battery)
● When the vehicle is continuously driven with the air intake vent blocked, the
traction battery may overheat and cause a decline in fuel consumption.
● The cleaning time for air intake vent differs depending on the driving envi-
ronment, etc.
■ Cleaning the cooling air intake vent
● If there are any uncertainties with cleaning the filter, consult any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. Han-
dling mistakes may lead to the cover or filter becoming damaged.
● When the vehicle is continuously driven with the filter clogged, the traction
battery may overheat which could lead to a decline in fuel consumption and
a breakdown.
● The cleaning time for filter differs depending on the driving environment, etc.
■ When the go to service warning light turns on (vehicles with mono-
chrome display) or “Maintenance re quired for Traction battery cooling
parts. See owner’s manual.” is displayed on the multi-information dis-
play (vehicles with color display)
● It is possible the air intake vent or filter is clogged due to accumulated dust.
Clean the air intake vent and filter, referring to the cleaning method.
● When continuously driven in this state, the hybrid battery (traction battery)
may overheat, which may lead to the driving distance by the electric motor
getting shorter, the fuel consumption worsening, and causing damage.
Clean the air intake vent periodically to prevent dust, etc., from collecting in
the air intake vent or filter.
● If the go to service warning light (vehicles with monochrome display) or the
display message in the Multi-Informat ion display (vehicles with color dis-
play) does not turn off, even if the air intake vent is cleaned, have the vehi-
cle inspected at any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer.
