■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 transmi ssion 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.
• The air conditioning system is being used when the vehicle interior tem-
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.

• Vehicles with an automatic air conditioning system: The windshield
defogger is turned on.
• The battery is not sufficiently charged.
• The vehicle starts to roll on an incline.
• Vehicles with a Multidrive: The hood is opened when the shift lever is in N
or P.
• Vehicles with a Multidrive: The shift lever is shifted into a position other
than N or P.
• The accelerator pedal is depressed.
• A large amount of electricity is being used.
• The driver’s door is opened.

■ 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.

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. 243, 246)
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. 343)
■ 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.
