*1: These lights turn on when the engine switch is turned to the “ON” position
(vehicles without a smart entry & start system) or IGNITION ON mode
(vehicles with a smart entry & start system) to indicate that a system check
is being performed. They will turn off after the engine is started, or after a
few seconds. There may be a malfunction in a system if a light does not
come on, or if the lights do not turn off. Have the vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

Driving

WARNING
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

YARIS_F_OM_Europe_OM52A54E
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. 585)
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. 512)
■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.

Maintenance and care
YARIS_F_OM_Europe_OM52A54E■
How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine 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. 659)
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 engine switch to the “ON” position (vehicles without a
smart entry & start system) or IGNITION 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 min-
utes with the engine switch in the “ON” position and then turn the
engine switch to the “ACC” or “LOCK” position.
Vehicles with a smart entry & start system: Wait for a few minutes
with the engine switch in IGNITION ON mode and then turn the
engine switch off.

5127-3. Do-it-yourself maintenance
YARIS_F_OM_Europe_OM52A54E
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■Replacing tire and wheels (vehicles with a tire pressure warning system)
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays
on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
■Low profile tires (vehicles with 195/50R16 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
■Routine tire inflation pressure checks (vehicles with a tire pressure
warning system)
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.

tem)

5147-3. Do-it-yourself maintenance
YARIS_F_OM_Europe_OM52A54E■When initialization of the tire pressure warning system has failed (vehi-
cles with a tire pressure warning system)
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
■Registering ID codes
The ID codes of the tire pressure warning valve and transmitters for two sets
of wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels of both normal tires and snow tires
are registered beforehand.
For information about changing ID codes, ask any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer as soon as possible.
