When to use the Stop & Start system
●If the engine is stopped by the Stop & Start system and the shift lever is
shifted into a position other than N with the clutch pedal released, a buzzer
will sound and Stop & Start indicator will flash. This indicates that the engine
is only stopped by the Stop & Start system, not that the engine has been
turned off completely.
● Use the Stop & Start system when stopping the vehicle temporarily at red
lights, intersections, etc. When stopping the vehicle for a longer period of
time, turn off the engine completely.
● When the system cannot operate, is canceled, or is malfunctioning, warning
messages and the warning buzzer are used to inform the driver. ( →P. 539)
● Vehicles with smart entry and start system: Even if the engine switch is
pressed during an engine stop, the engine does not restart. Start the engine
by shifting the shift lever to N and performing a normal engine start opera-
tion.
● When the engine restarts after having been stopped by the Stop & Start sys-
tem, the power outlet may be temporar ily unusable, but this does not indi-
cate a malfunction.
● Installation and removal of electrical components and wireless devices may
affect the Stop & Start system, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■ If the windshield is fogged up while the engine is stopped by the Stop &
Start system
Turn the windshield defogger on. (The engine will start due to the automatic
engine start function.) ( →P. 394, 401)
If the windshield fogs up frequently, press the Stop & Start cancel switch to
deactivate the system.
■ Air conditioning system while the engine is stopped by the Stop & Start
system (vehicles with an air conditioning system)
While the engine is stopped by the Stop & Start system, the air conditioning
system (cooling, heating and dehumidifying functions) is cancelled and it only
blows air or stops blowing air. In order to prevent the air conditioning system
from being cancelled, deactivate the Stop & Start system by pressing the Stop
& Start cancel switch.

AVENSIS_OM_OM20C66E_(EE)
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior.
● Vehicles with air conditioning system : During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
■ When the outside temperature falls to nearly 0°C (32°F) (vehicles with air
conditioning system)
The dehumidification function may not operate even when is
pressed.
■ 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.
■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with Stop & Start system)
When the engine is stopped due to the Stop & Start system operations, the air
conditioning cooling, heating and dehumidif ication functions turn off and only
ambient temperature air is blown, and there is a possibility that the blowing of
ambient temperature air will stop. To prevent the air conditioning system from
turning off, press the Stop & Start cancel switch to deactivate the system.
■ When the windshield is fogged up and the engine is stopped due to the
Stop & Start system (vehicles with Stop & Start system)
Press the Stop & Start cancel switch to restart the engine and turn
on to defog the windshield. Simply pressing will restart the engine
and defog the windshield.
If the windshield continuously fogs up, press the Stop & Start cancel switch
and refrain from using the Stop & Start system.
