■Automatic car washes
● Fold the mirrors and remove the antenna before washing the vehicle. Start
washing from the front of the vehicle. Make sure to re-install the antenna
and extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
● Rear spoiler (if equipped) may not be washable in some automatic car
washes. There may also be an increased risk of damage to vehicle.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity of
the windows and door borders, and high mounted stoplight.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ When using a car wash (vehicles with a smart entry & start system
equipped with entry function)
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position
2 m (6 ft.) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
■ 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 following pre-
cautions.
• 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 driv-
ing or parking in hot weather
■ Bumpers
Do not scrub with abrasive cleaners.

NOTICE
■When using an automatic car wash (vehicles with a rain-sensing wind-
shield wiper)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wiper may operate and the wiper blade
may be damaged.
■ To prevent damage to the antenna
Remove the antenna in the following situations:
● When the antenna will touch the ceiling of a garage or other such places
● When a car cover is to be used to cover the vehicle
■ When using a high pressure car wash
● Vehicles with back camera: When washing the vehicle, do not let water of
the high pressure washer hit directly or the vicinity of the camera. Due to
the shock from the high pressure water, it is possible the device may not
operate as normal.
● Do not bring the nozzle tip close to boots (rubber or resin manufactured
cover), connectors or the following parts. The parts may be damaged if
they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts

■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.

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is carried
out approximately every 10000 km
(6000 miles).
When rotating front and rear tires
which have different tire inflation
pressures, do not fail to initialize
the tire pressure warning system
after tire rotation.
Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Toyota recommends
that tire rotation is carried out approximately every 10000 km
(6000 miles).

Maintenance and care
YARIS_HV_OM_Europe_OM52J66E
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. ( P. 522)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new ID codes must be registered in the tire pressure warning com-
puter and the tire pressure warning system must be initialized. Have
tire pressure warning valve and transmitter ID codes registered by
any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer. ( P. 455)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating front and rear tires which have different tire infla-
tion pressures
● When the tire inflation pressure is changed such as when chang-
ing traveling speed
● When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
Tire pressure warning system (if equipped)

■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the power switch to the
“LOCK” position (vehicles without a smart entry & start system)
or off (vehicles with a smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 598)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the power switch to the “ON” position (vehicles without a
smart entry & start system) or ON mode (vehicles with a smart
entry & start system).
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
Vehicles without a smart entry & start system:
Wait for a few minutes with the power switch in the “ON” position
and then turn the power switch to the “ACC” or “LOCK” position.
Vehicles with a smart entry & start system:
Wait for a few minutes with the power switch in ON mode and
then turn the power switch off.
