Audi A6 Typ 4G: Stopping/starting the engine

Applies to: vehicles with Start/Stop system

Fig. 80 Instrument cluster: engine switched off (stop phase)

• Brake the vehicle to a stop. The engine stops shortly before the vehicle comes to a stop or if the vehicle is stationary. Keep your foot on the brake pedal. The indicator light appears in the information line at the bottom of the instrument cluster display. The needle in the tachometer also moves into the READY position.
• The engine starts again when you take your foot off the brake pedal. The indicator light turns off.

Additional information

The engine stops in the P, N and D selector lever positions.

If you select the R position during a stop phase, the engine will start again.

Shift to P quickly to prevent the engine from starting unintentionally when shifting through R.

You can determine for yourself if the engine will stop or not by reducing or increasing the amount of force you use to press the brake pedal. For example, if you only lightly press on the brake pedal in stop-and-go traffic or when turning, the engine will not switch off when the vehicle is stationary.

As soon as you press the brake down harder, the engine will switch off.

General information

Applies to: vehicles with Start/Stop system

The standard Start/Stop mode con be canceled for various system-related reasons.

Engine does not switch off

Before and during each stop phase, the system checks if certain conditions have been met. If the indicator light appears in the instrument cluster display, the engine will not be stopped, for example in the following situations:

• The engine has not reached the minimum required temperature for Start/Stop mode.
• The interior temperature selected by the A/C system has not been reached.
• The outside temperature is extremely high/low.
• The windshield is being defrosted .
• The parking system is be switched on.
• The vehicle battery charge level is too low.
• The steering wheel is turned at a sharp angle or is moving.
• After engaging the reverse gear.
• On sharp inclines.

Engine automatically restarts

The standard Start/Stop mode will be canceled during a stop phase in the following situations.

The engine restarts without any action by the driver.

• The vehicle rolls, for example while on a slope.
• The interior temperature differs from the temperature selected in the A/C system.
• The windshield is being defrosted .
• The brake pedal is pressed several times in a row.
• The vehicle battery charge level is too low.
• Power consumption is high.

The engine can turn off again when the conditions for Start-Stop mode are met.

Ignition is switched off automatically

To prevent the vehicle battery from draining, the ignition will switch off automatically under the following conditions:

• The vehicle must have already been driven.
• The Start/Stop system has stopped the engine.
• The driver's door must be open.
• The driver's safety belt must be unbuckled.
• The brake pedal must not be pressed.
• The vehicle must be stationary.

In this case, the activated low beam is replaced by the parking light. The parking lights will switch off after approximately 30 minutes or when you lock the vehicle.

If the Start/Stop system has not turned off the engine or if you have switched the Start/Stop system off manually, the ignition will not be automatically switched off and the engine will continue to run.

WARNING

To reduce the risk of poisoning, never allow the engine to run in confined spaces.

Tips

If you select the D or N selector lever position after shifting into reverse, the vehicle must be driven faster than 6 mph (10 km/h) in order for the engine to switch off again.
