3524-6. Using the driving support systems
YARIS_F_OM_Europe_OM52K19E
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
● The emergency flashers are off
● Actual vehicle speed is over 55 km/h (35 mph)
● The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation
■ Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
● The emergency flashers are turned on
● The brake pedal is released
● The system judges from the vehicle deceleration that is not a sudden brak-
ing operation

4486-1. Using the air conditioning system and defogger
YARIS_F_OM_Europe_OM52K19E
■ Ventilation and air conditioning odors
● To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in AUTO mode.
■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with a Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the auto-
matic air conditioning cooling, heating and dehumidification functions turn off
and the fan speed is decreased according to the outside temperature etc. or
air blowing stops. To stop the air conditioning system from turning off, press
the Stop & Start cancel switch and refr ain from using the Stop & Start system.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.

Seat heaters
: If equipped
WARNING
■Burns
● Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
■ To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■ To prevent battery discharge
Turn the seat heaters off when the engine is not running.
