Fig. 138 On the instrument cluster display: ACC active, vehicle detected on the left.

Always remain fully aware of the operational limitations and safety warnings described at the beginning of this chapter under Introduction.

Avoid undertaking on the right

If another vehicle is detected travelling in the left lane at a speed slower than your preselected cruising speed, your Seat Leon will automatically decelerate within comfortable system limits to prevent illegally passing it on the right ››› Fig. 138.

You can override and cancel this regulatory deceleration at any time by firmly depressing the accelerator pedal.

This intelligent function operates at vehicle speeds exceeding 80 km/h (50 mph) and may not be available in certain regional markets or countries.

Overtaking

When you switch on the directional turn signal to indicate an overtaking manoeuvre, the ACC temporarily reduces the following distance to the vehicle directly in front to support and streamline your passing action.

However, the system will never exceed your programmed cruising speed limit during this process.

This active overtaking support works at speeds over 80 km/h (50 mph) and may vary depending on local country specifications.

Stop&Go function

The Adaptive Cruise Control system can bring your Seat Leon to a complete standstill if the vehicle travelling in front of you stops.

On models equipped with manual gearboxes, you will need to keep the clutch pedal depressed to allow the car to come to a full stop without stalling.

The ACC remains temporarily active while stationary, and the advisory message "ACC ready to start" is displayed on the instrument cluster screen for a few seconds. You can extend or reactivate this ready window by pressing the button or by gripping the steering wheel if your car is equipped with Travel Assist. During this active standstill window, your vehicle will automatically move off again as soon as the vehicle ahead starts moving forward.

To resume driving when the "ACC ready to start" message is no longer displayed, once the leading vehicle has moved away:

• On vehicles with automatic transmission: Briefly depress the accelerator pedal.

On vehicles with a manual gearbox: Briefly depress the accelerator pedal and gently lift the clutch pedal.

• OR: Press the button on the multifunction steering wheel.
• OR: Grip the steering wheel firmly again if your vehicle is equipped with Travel Assist.

The ACC does not remain active and will disengage under the following conditions:

• The stationary waiting phase lasts for several continuous minutes.
• Any vehicle door is opened while stopped.
• The ignition is switched off.

WARNING When the message "ACC ready to start" is displayed on the instrument cluster screen and the leading vehicle moves off, your Seat Leon will accelerate and move forward automatically. In this active phase, sudden obstacles or pedestrians in the road may not be detected in time.

This can lead to severe collisions and personal injuries.

• Always visually check the road ahead before moving off, and apply the vehicle's service brakes yourself if necessary.
