Maintenance for the cooling air intake vent of the hybrid battery
(traction battery)

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.

WARNING
■Water in the vehicle
● Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vents, and in the rear seat. Doing so
may cause the hybrid battery, electrical components, etc., to malfunction
or catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 44)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.
■ When doing maintenance on the cooling air intake vent and filter for
the hybrid battery (traction battery)
● Do not clean using water or any liquids. If the hybrid battery gets wet, there
is a danger of the battery being damaged leading to a vehicle fire.
● When removing the lower rear seat cover (left side), be sure to turn the
power switch OFF and stop the hybrid system.

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

■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non- nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35°C [-31°F])
For more details about coolant, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer, test the cap and check for leaks in the
cooling system.
WARNING
■ When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■ When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

WARNING
■Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12-volt battery:
● Do not cause sparks by touching the 12-volt battery terminals with tools.
● Do not smoke or light a match near the 12-volt battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the 12-volt battery.
● Keep children away from 12-volt battery.
■ Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-
volt battery in a garage or closed room where there is insufficient ventila-
tion.
■ When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first. If the positive (+) terminal
is disconnected first and touches a surrounding metal surface sparks will be
produced, possibly starting a fire. It could also result in an electric shock or
serious injury.
■ How to recharge the 12-volt battery
Only perform a slow charge (3.5 A or less). The 12-volt battery may explode
if charged at a quicker rate.
