Start/Stop – Auto-start exceptions
Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving, for instance in heavy traffic or at a traffic light to help reduce fuel consumption.
In certain situations or conditions, the engine may auto-start even though the driver is still pressing the brake pedal, such as if:
| Condition/situation |
|---|
| Condensation forms on the windows. |
| The climate system cannot keep the desired settings in the passenger compartment. |
| Electrical current consumption is temporarily high or the main battery's charge is below the minimum level. |
| The brake pedal is pumped repeatedly. |
| The hood has been opened1. |
| The vehicle begins to move or increases speed slightly (if the engine auto-stopped before the vehicle was at a standstill (see ECO*)). |
| The driver unbuckles his/her seat belt while the gear selector is in the D or N positions. |
| The steering wheel is turned1. |
| The gear selector is moved from D to S2, R or "+/–". |
| The driver's door is opened with the gear selector in D – an audible signal and a text message will inform the driver that Start/Stop is active. |
Warning
Do not open the hood if the engine has auto-stopped. The engine could suddenly auto-start.
Before opening the hood:
- Switch off the ignition using the START/STOP ENGINE button.
- Be aware that if the engine has been running, components in the engine compartment will be very hot.
If the engine does not auto-start, this could be due to:
- The driver's seat belt is not fastened
- The gear selector is in P and the driver's door is opened
In these cases, the driver will have to restart the engine by pressing the START/STOP ENGINE button.
