Get Driving -> Start/stop system Guide for Volkswagen T-Roc SUV First Generation (2017-2025)

Functional description

The start/stop system automatically switches off the engine shortly before stopping or when the vehicle comes to a standstill and

when the vehicle is stationary.

On vehicles with manual gearbox, the engine switches off only if no gear is engaged and the clutch pedal is not pressed when coasting

to a stop or at vehicle standstill.

The engine restarts automatically whenever necessary for the vehicle and the detected situation.

The function is automatically activated every time the ignition is switched on.

Indicator lamps

The instrument cluster display will show information about the current status.

If the indicator lamp lights up, the start/stop system is available and automatic engine stop is active.

If the

indicator lamp lights up, the start/stop system is not available or the start/stop system has started the engine automatically.

Conditions for an automatic restart of the engine

—Vehicles with an automatic gearbox: When the foot is taken off the brake pedal or the accelerator is pressed.

—Vehicles with a manual gearbox: If the clutch is pressed.

—If the temperature in the vehicle interior greatly increases or decreases.

—If the vehicle starts rolling.

—If the electric voltage of the 12-volt vehicle battery drops.

Start-Stop mode with automatic Adaptive Cruise Control (ACC)

The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a standstill with an active braking

intervention.

In the following instances, the engine will restart when ACC is active:

—If the accelerator is pressed.

—When ACC has resumed speed and distance control.

—If the vehicle ahead has moved on.

The engine will also be restarted if the Adaptive Cruise Control (ACC) is deactivated and the vehicle ahead moves further away.

selection.

WARNING

The engine can start suddenly if the start/stop system is activated when working in the bonnet space. This can lead to accidents and

serious injuries.

● Always deactivate the start/stop system when working in the bonnet space.

WARNING

When the engine is switched off, certain vehicle systems do not function or function only to a restricted extent, e.g. brake servo or

power steering. As a result, more force has to be used for steering and more pressure has to be applied to the brake pedal to stop the

vehicle. If the vehicle is in motion, this can cause loss of control over the vehicle, accidents and serious or fatal injuries.

● Never switch off the engine while the vehicle is in motion.

WARNING

The airbags and belt tensioners do not function when the engine is switched off. This can result in accidents and serious or fatal

injuries.

● Never switch off the engine while the vehicle is in motion.

WARNING

When the ignition is switched off, the steering lock may activate and you will no longer be able to steer the vehicle. If the vehicle is in

motion, this can cause loss of control over the vehicle, accidents and serious or fatal injuries.

● Never switch off the ignition while the vehicle is in motion.

NOTICE

If the start/stop system is used in very high outside temperatures over a long period, the 12-volt vehicle battery can be damaged.

● Avoid using the start/stop system at very high outside temperatures.

Engine no longer starts automatically

1. Start the engine manually (→ Starting the engine).

2. Deactivating the start/stop system manually (→ Start/stop system).

3. In this case, go to a suitably qualified workshop and have the system checked. Volkswagen recommends using an authorised
