Audi Q5: Starting/stopping the engine

Applies to vehicles: with Start-Stop-System

Fig. 104 Instrument duster: Engine switched off (stop phase)

• Slow the vehicle to a stop using the brake and keep pressing the brake pedal. The engine will switch off. The indicator light appears in the instrument cluster display and also appears in the trip computer.
• When you take your foot off the brake pedal, the engine restarts. The indicator light turns off.

Additional information

The engine will switch off in the P, D/S and N positions as well as in manual mode. In the P position, the engine will also remain off if you take your foot off the brake pedal. The engine starts again when you select another selector lever position and take your foot off the brake pedal.

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

Shift from D/S 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 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.

Tips

• Press the brake pedal during a stop phase to keep the vehicle from rolling.
• The ignition will turn off if you press the button during a stop phase.
• The image in the display is slightly different in some models.

Engine will not switch off

Before each stop phase, the system checks if certain conditions have been met. For example, the engine will not be switched off in the following situations:

• The engine has not reached the minimum required temperature for Start-Stop-mode.
• The interior temperature selected by the А/С system has not been reached.
• The outside temperature is extremely high/low.
• The windshield is being defrosted.
• The parking system is switched on.
• The battery charge level is too low.
• The steering wheel is sharply turned or there is a steering movement.
• After engaging the reverse gear.
• On sharp inclines.

Engine automatically restarts

The stop phase is interrupted in the following situations, for example. The engine restarts without any action by the driver.

• The interior temperature varies from the temperature selected in the А/С system.
• The windshield is being defrosted.
• The brake pedal is pressed several times in a row.
• The battery charge level becomes too low.
• High power consumption.

Switching the ignition off automatically

To prevent the battery from draining, the ignition will switch off automatically when all of the following conditions have been met:

• The vehicle has already been driven.
• The engine has been turned off by the Start-Stop- System.
• The driver's door is opened.
• The driver's seat belt is removed.
• The brake pedal is not pressed down.
• The vehicle is stationary.

In this case, the activated low beam will be replaced by the side marker lights. The side marker 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

Never allow the engine to run in confined spaces - danger of asphyxiation.

Tips

If you shift into the D/S or N positions 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.
