Stop/start Prohibition Condition Evaluated By A/C Auto Amp. (During Stop/start Operation)
During stop/start operation, when any of the following conditions is met, A/C auto amp. judges that stop/start
system operation is prohibited, cancels stop/start permit signal (inhibit), and requests ECM to restart engine.
• AUTO switch: Pressed
• A/C switch: Pressed.
• MAX DEF switch (for Europe and Russia) / DEF switch (except for Europe and Russia): Pressed [only when
ambient temperature is 25
°
C (77
°
F) or less]
• Passenger room temperature: Becomes 20
°
C (68
°
F) or less (when A/C switch is ON/OFF) or 30
°
C (86
°
F) or
more (only when A/C switch is ON)
• Evaporator temperature: Becomes 16
°
C (60.8
°
F) or more (only when A/C switch is ON)
A/C CONTROL DURING STOP/START OPERATION
During stop/start operation, A/C auto amp. changes air flow and control characteristics of air inlet within a
range that does not adversely affect the comfort level, prolongs stop/start operation time and reduces power
consumption for improving fuel economy. Refer to the following items for details of each control.
Air Flow Control
Air flow reduction control during stop/start operation
• A/C auto amp increases voltage to power transistor gate compared to ordinary operation and reduces volt-
age to blower motor. This reduces air flow.
• Due to reduced airflow, the amount of air that passes evaporator is reduced. Increase of evaporator temper-
ature can be moderated. This helps prevent a rise in evaporator temperature from meeting the stop/start
prohibition condition, prolonging stop/start operation time.
• Also, by decreasing the voltage applied to blower motor, power consumption is reduced. This moderates
alternator power output after engine is restarted.
NOTE:
When the fan switch is operated while stop/start is operating, the air flow changes to the setting from before
stop/start is activated. (The air flow indicator also changes in the same way.)
Air Inlet Control
Air inlet change control during stop/start operation
• A/C auto amp. increases recirculation air mixing ratio compared to ordinary operation.
• By increasing recirculation air mixing ratio, cooled air in passenger room is circulated in larger amount than
during ordinary operation and increase of evaporator temperature can be moderated. This helps prevent
stop/start prohibition condition (evaporator temperature) from being met and prolongs stop/start operation
time.
