If the Stop & Start cancel switch is pressed while the vehicle is
stopped
●When the engine is stopped by the Stop & Start system, pressing
the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
●With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
After the engine is stopped by the Stop & Start system when the vehi-
cle is on an incline, brake force is temporarily maintained to prevent
rolling backwards until the engine is restarted and drive force is gener-
ated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
●This function operates on flat surfaces as well as steep inclines.
●Sound may be generated from the brakes, but this is not a malfunc-
tion.
●Brake pedal response may change and vibration may occur, but
these are not malfunctions.

●In the following circumstances the engine may not be stopped by the Stop &
Start system. This is not a malfunction of the Stop & Start system.
• Engine coolant temperature or transmission fluid temperature is too low
or too high.
• The outside temperature is extremely low.
• The air conditioning system is being used when the outside temperature
is high or low.

perature is extremely high such as after the vehicle was parked under the
hot sun.
• Vehicles with an automatic air conditioning system: The windshield
defogger is being used.
• The battery is undergoing a periodic recharge.
• The battery is not sufficiently charged, such as if the vehicle has been
parked for a long time and the battery charge has decreased, the electric
load is large, the battery fluid temperature is excessively low or the bat-
tery has deteriorated.
• The battery fluid temperature is extremely low or high.
• Due to traffic or other circumstances the vehicle is stopped repeatedly,
resulting in the amount of time the engine is stopped by the Stop & Start
system to become excessively high.
• The driver’s seat belt is unfastened.
• The driver’s door is opened.
• The hood is opened.
• The vehicle is stopped on a steep hill.

YARIS_F_OM_Europe_OM52A54E■The Stop & Start system protection feature
Vehicles without a smart entry & start system
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the engine switch to the “LOCK” position then to the
“ACC” or “ON” position re-enables the audio system.
Vehicles with a smart entry & start system
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the engine switch off then to ACCESSORY mode or
IGNITION ON mode re-enables the audio system.
■Hood
Even if the hood is closed after the engine is started with the hood open, the
Stop & Start system will not operate. Close the hood, turn the engine switch
off, wait 30 seconds or more, and then start the engine. (P. 241, 243)
Vehicles with a Multidrive: If the hood is opened while the engine is stopped
by the Stop & Start system and the shift lever is in N or P, the engine will
restart.
■When to use the Stop & Start system
When the system does not operate, is canceled, or is malfunctioning, warning
messages (vehicles with color display only) and a warning buzzer are used to
inform the driver. (P. 350)
■Stop & Start system warning buzzer
If the engine is stopped by the Stop & Start system and either of the following
actions is performed, a buzzer will sound and the Stop & Start indicator will
flash (Multidrive), or a buzzer will sound (manual transmission). This indi-
cates that the engine is only stopped by the Stop & Start system, not that the
engine has been turned off completely.
Vehicles with a Multidrive
The driver’s door is opened when the shift lever is in D or M.
Vehicles with a manual transmission
The shift lever is shifted into a position other than N with the clutch pedal
released.

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.
