■ Air conditioning system operation while the engine is stopped by the
Stop & Start system
● If the air conditioning system is being used in automatic mode, the fan
speed may be reduced or the fan may be stopped while the engine is
stopped by the Stop & Start system in order to reduce changes in the cabin
temperature.
● To ensure air conditioning system performance when the vehicle is stopped,
disable the Stop & Start system by pressing the Stop & Start cancel switch.

WARNING
■When the Stop & Start system is operating
● Keep the shift lever in N (manual transmission) and apply the brake pedal
or parking brake for safety while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Do not leave the vehicle while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Ensure that the engine is not stopped by the Stop & Start system while the
vehicle is in a poorly ventilated area. The engine may restart due to the
automatic engine start function, causing exhaust gases to collect and
enter the vehicle and resulting in death or a serious health hazard.

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control (if equipped)
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆Emergency brake signal
When the brakes are applied suddenly, the emergency flashers
automatically flash to alert the vehicle behind.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

YARIS_F_OM_Europe_OM52A54E■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●Vehicles with Multidrive: The shift lever is in a position other than P or N
(when starting off forward/backward on an upward incline).
●Vehicles with manual transmission: The shift lever is in a position other than
R when starting off forward on an upward incline, or the shift lever is in R
when starting off backward on an upward incline.
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●Vehicles with Multidrive: The shift lever is shifted to P or N.
●Vehicles with manual transmission: The shift lever is shifted to R when start-
ing off forward on an upward incline, or the shift lever is shifted to other than
R when starting off backward on an upward incline.
●The accelerator pedal is depressed.
●Approximately 2 seconds elapse.
●2 seconds at maximum elapsed after the brake pedal is released.
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRC, and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.

4466-1. Using the air conditioning system and defogger
YARIS_F_OM_Europe_OM52A54E■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.
■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.

• 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 refrain from using the Stop & Start system.
