The engine does not auto-stop in the following cases:

  • The car has not reached approx. 10 km/h (6 mph) after starting.
  • After a number of repeated auto stops, speed must again exceed approx. 10 km/h (6 mph) before the next auto stop.
  • The driver has unfastened the seatbelt.
  • The capacity of the starter battery is below the minimum permissible level.
  • The engine is not at normal operating temperature.
  • The ambient temperature is under -5 °C (23 °F) or above approx. 30 °C (86 °F).
  • The windscreen's electric heating is activated.
  • The environment in the passenger compartment deviates from the set values.
  • The car is reversed.
  • The starter battery's temperature is below or above the permitted limit values.
  • The driver makes sweeping steering wheel movements.
  • The road is very steep.
  • The bonnet is opened.
  • When driving at high altitudes when the engine has not reached operating temperature.
  • The ABS system has been activated.
  • In the event of heavy braking (even without the ABS system having been activated).

The engine does not auto-start

In the following cases the engine does not auto-start after having auto-stopped:

  • The driver is unbelted, the gear selector is in P position and the driver's door is open - a normal start must take place.

With manual gearbox:

  • The driver is unrestrained.

Involuntary stop with manual gearbox

If a start-up fails and the engine stops, proceed as follows:

  1. Check that the driver side's seatbelt is locked in the seatbelt buckle.
  2. Depress the clutch pedal again - the engine starts automatically.
  3. In certain cases the gear lever must be set in neutral position. A message is shown in the driver display - follow the recommendation given.

In the following cases, the engine auto-starts even if the driver does not take his/her foot off the brake pedal:

  • High humidity in the passenger compartment forms misting on the windows.
  • The environment in the passenger compartment deviates from the set values.
  • There is a temporarily high current take-off or starter battery capacity drops below the lowest permissible level.
  • Repeated pumping of the brake pedal.
  • The bonnet is opened.
  • The car starts to roll or increase speed slightly if the car auto-stopped without being completely stationary.

The following applies to automatic gearbox:

  • The driver's seatbelt buckle is opened with the gear selector in D or N position.
  • The gear selector is moved from D to R or M (±) position.
  • The driver's door is opened with the gear selector in D position - a "ping" sound and text message indicate that the ignition is on.
