Audi Q7: Start/Stop system

Description

Applies to: vehicles with Start/Stop system

The Start/Stop system can help increase fuel economy and reduce CO2 emissions.

In Start/Stop mode, the engine shuts off automatically when stopped, for example at a traffic light. If certain conditions are met, the engine may stop before the vehicle has come to a complete stop. If you press the accelerator pedal when this happens, the engine will start and driving power will be transmitted.

The ignition and important assist systems such as the brake booster will remain available during the Stop phase. The engine will restart automatically when needed.

The Start/Stop system is automatically activated once the ignition is switched on.

Switching the Start/Stop system off and on

The button is located above the selector lever in the center console. The LED in the button turns on when the function is switched off.

• Press to switch the system on or off.

If you switch the system off during a Stop phase, the engine will start again automatically.

Basic requirements

• The driver's door and the hood must be closed and the driver's safety belt must be fastened.
• "P", "N", or "D" must be engaged.
• The steering wheel must not be turned far in either direction.
• The vehicle must have driven faster than 2 mph (3 km/h) since the last time it stopped.
• The vehicle is not in trailer mode.

Note

Always switch the Start/Stop system off when driving through water.

Tips

• Depending on the driving situation, the engine may already stop when coasting before the vehicle has come to a complete stop.
• If you select the "D" position after shifting into reverse, the vehicle must be driven faster than 6 mph (10 km/h) in order for the Start/Stop system to become active again.

  This makes it possible to maneuver without stopping the engine.

Stopping and starting the engine

Applies to: vehicles with Start/Stop system

• Press and hold the brake pedal until the vehicle has stopped. The indicator light appears in the instrument cluster once the engine stops automatically.
• The engine starts again when you remove your foot from the brake pedal. The indicator light turns off.

If the parking brake is set, the engine will only start again when the accelerator pedal is pressed.

Tips

• Press the brake pedal during a Stop phase to keep the vehicle from rolling.
• The ignition will turn off if you press the START ENGINE STOP button during a Stop phase.
• If you leave the vehicle briefly during a Stop phase and then enter again, the driver's door must be closed and the safety belt must be fastened in order for the engine to be able to restart.
• You can control 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. If you press the brake pedal harder, the engine will switch off.

Starting and stopping the engine automatically

Applies to: vehicles with Start/Stop system

The system checks if certain conditions are met before and during the Stop phase, and determines if the engine stops and how long it remains stopped. For example, if power usage is high, the engine will not be stopped. Along with other conditions, the following factors influence the automatic engine start or stop:

• Environmental conditions (slopes, inclines, elevation, temperature)
• Battery (charge status, temperature, power usage)
• Engine temperature
• Assist systems
• Driving behavior

Messages

Applies to: vehicles with Start/Stop system

The following messages may appear depending on the vehicle equipment:

Drive system: please start the vehicle manually

This message appears when specific conditions are not met during a Stop phase. The Start/Stop system will not be able to restart the engine. The engine must be started with the START ENGINE STOP button.

Vehicle starting system: malfunction! Please contact Service
