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.

Maintenance and care
YARIS_HV_OM_Europe_OM52J66E
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Vehicles without a smart entry & start system: Make sure that the power
switch is in the “LOCK” position and the “READY” indicator are off.
● Vehicles with a smart entry & start system: Make sure that the “Power 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 fluids
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 damage
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
Vehicles without a smart entry & start system
Be sure the power switch is in the “LOCK” position.
With the power switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 443)
Vehicles with a smart entry & start system
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fan may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 443)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.

Tire inflation pressure
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
● Reduced fuel economy
● Reduced driving comfort and poor handling
● Reduced tire life due to wear
● Reduced safety
● Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■ Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
● Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation
pressure reading.
● Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
● It is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. ( P. 598)
