PRECAUTION
PRECAUTIONS WHEN INSPECTING STOP AND START SYSTEM
NOTICE:
When the audio and visual system volume is high, a fail-safe function may operate in order to maintain the operation of stop and start control. The fail-safe function is canceled when the ignition switch is turned off. Using the same power source for the audio and visual system and other systems allows the fail-safe functions to operate more precisely.

PRECAUTIONS WHEN AUXILIARY BATTERY IS DISCHARGED AFTER LEAVING VEHICLE FOR A LONG TIME
HINT:
If the vehicle has not been driven for a long time, the auxiliary battery charge will be low and stop and start control operation will be prohibited. If the integrated current value does not exceed the threshold*1 even though the auxiliary battery has been charged until the charging current decreases to 5 A or less, perform an integrated current value initialization*2 and drive the vehicle for approximately 5 to 40 minutes until the stop and start system operates.
*1: Refer to System Description for details on the integrated current threshold.

*2: Use the GTS to perform Integrated Current Value Initialization.

PRECAUTIONS WHEN CONNECTING/DISCONNECTING CABLE TO/FROM NEGATIVE AUXILIARY BATTERY TERMINAL
HINT:
In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item Status of Battery Charge Control changes from "Refresh Charge Mode". (Usually, by idling the engine for 5 to 60 minutes with the auxiliary battery fluid temperature at 11°C (52°F) or higher, the refresh charge will be completed.)
If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.
(a) If power is not supplied to the audio and visual system when the ignition switch is turned to ON for the first time after the auxiliary battery has been reconnected, DTC P323A19 will be stored. Perform either of the following operations:
(1) Turn the ignition switch from ON to off twice.
(2) After turning the ignition switch from ON to off, clear the DTCs.
Powertrain > Stop and Start > Clear DTCsIF THE ENGINE FAILS TO RESTART FROM IDLING STOP
NOTICE:
If the engine fails to restart when stopped by stop and start control, the brake actuator may be activated.
Brake actuator activation conditions:
*: When the engine is not running.

PRECAUTIONS AFTER CHARGING AUXILIARY BATTERY
HINT:
If the auxiliary battery is replaced or charged with the cables connected after stop and start control has been prohibited due to a low auxiliary battery charge, perform the integrated current value initialization using the GTS.

If the Data List item "Integrated Current" indicates 0 A-sec or more, initialization is not necessary.
PRECAUTIONS FOR FOUR-WHEEL TOWING
NOTICE:
If the vehicle is to be towed with all four wheels on the ground, turn the ignition switch off and then to ON without starting the engine. Only tow the vehicle at speeds below 30 km/h (19 mph) for distances of less than 80 km in a forward direction.
