disabled by the Stop & Start cancel switch, it will be automatically re-enabled
once the engine switch is turned off then the engine is started.
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 auto-
matically cut off in order to maintain power for the Stop & Start system func-
tion.
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 automati-
cally 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.

3664-5. Using the driving support systems
UK_AURIS/AURIS_HV_EE (OM12F76E)When to use the Stop & Start system
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.
Stop & Start system warning buzzer
If the engine is stopped by the Stop & Start system and the following action is
performed, a buzzer will sound and the 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.
The shift lever is shifted to a position other than N with the clutch pedal
released.
If the Stop & Start cancel indicator continues to flash
The Stop & Start system may be malfunctioning. 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

UK_AURIS/AURIS_HV_EE (OM12F76E)Reduced effectiveness of the EPS system
Except hybrid model: The effectiveness of the EPS system is reduced to pre-
vent the system from overheating when there is frequent steering input over
an extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the engine off. The effectiveness will improve after a short while.
Hybrid model: The effectiveness of the EPS system is reduced to prevent the
system from overheating when there is frequent steering input over an
extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the hybrid system off. The effectiveness will improve after a short
while.
