Introduction

The advanced speed limiter with proactive speed adjustment on your Seat Leon is designed to automatically adapt a maximum speed limit that you have previously saved to match detected, changing speed limits along your route.

The proactive speed limiter operates as an intelligent extension of the standard speed limiter system, seamlessly utilizing dynamic road sign display data from the infotainment system alongside integrated navigation map data.

This sophisticated proactive speed adjustment function is available depending on the specific equipment level of your Seat Leon, though availability may vary across different countries and regions.

WARNING The smart assistance technology behind the speed limiter with proactive speed adjustment cannot defy the unyielding laws of physics and operates only within established system boundaries. Never allow the increased driving convenience offered by this function to tempt you into taking risks that compromise safety. Serious accidents and severe injuries can occur if this proactive speed limiter is used carelessly or without proper driver supervision.

This automated system is never a replacement for continuous driver alertness and active awareness.

• Always adapt your vehicle speed and driving style to match prevailing visibility, weather, road surface, and traffic conditions.
• Always maintain full attention on the surrounding traffic and keep your eyes focused on the vehicle's environment at all times.
• Always remain fully prepared to take over and adjust your speed manually. If the road sign recognition system experiences a fault or if navigation map data is outdated, the vehicle speed may change unexpectedly and suddenly, or may no longer be appropriate for the immediate traffic situation. Furthermore, the speed chosen by the system may not always match your personal driving style.
• Always be ready to regulate your speed yourself. If you drive without an active route guidance destination set, if you deviate from the route calculated by the onboard navigation system, or if vehicle positioning is inaccurate because GPS satellite signals are weak, vehicle speed could adjust abruptly and inappropriately for current traffic conditions.
• Always ensure you update your navigation data regularly to keep map information current.
• Always observe official road speed limits independently. In situations where temporary or new speed restrictions are not yet included in the navigation database, the vehicle may exceed local speed limits if relied upon blindly.

Note Please also make sure to read and observe all general safety instructions and operational warnings relevant to the standard speed limiter.

Limitations of proactive speed adjustment

In addition to the standard operational boundaries associated with the dynamic road sign display system, the advanced speed limiter with proactive speed adjustment on your Seat Leon features several limitations that are inherent to the design of the system:

• The speed limiter with proactive speed adjustment is only capable of recognising physical or electronic road signs displaying an explicit numerical speed limit.
• Road signs or geographical markers that imply a speed restriction indirectly—such as standard town or city boundary entry signs—are recognised exclusively on the basis of onboard navigation map data.
• If the vehicle issues a warning for a speed restriction based solely on navigation database data without that specific sign being detected directly by the dynamic road sign camera, the indicated target speed will adjust back to the most recently saved baseline speed.
• The speed limiter with proactive speed adjustment is unavailable for detected speed restrictions lower than approximately 30 km/h (approx. 20 mph). Whenever such a zone is encountered, a corresponding explanatory message is shown on the instrument cluster display.

Activate proactive speed adjustment

The speed limiter with proactive speed adjustment can be easily enabled through the dedicated assistants configuration menu inside your vehicle's infotainment system.

Driving with proactive speed adjustment

• Activate the proactive speed adjustment feature within the menu settings.
• Switch on the main speed limiter and initiate active speed regulation.
• When the system successfully recognises a new speed limit sign, an advisory warning is displayed on the instrument cluster. This new speed threshold is then automatically stored in the speed limiter memory.

The system has recognised a new speed limit and is now using it for active speed regulation.

Interrupting speed adjustment

• Press the designated multifunction steering wheel button or release and press the accelerator pedal down twice rapidly.

  Following this action, the previously saved cruising speed is resumed.

• Press the button on the multifunction steering wheel. The current driving speed is adopted as the new limit.
• Press the button on the multifunction steering wheel. The system switches over to a passive standby state.

Adjust the displayed speed using the buttons on the multifunction steering wheel

+ 1 km/h (1 mph)

- 1 km/h (1 mph)

+ 10 km/h (5 mph)

- 10 km/h (5 mph)

If you adjust the indicated target speed excessively away from the detected limit, proactive speed adjustment is temporarily interrupted.

Note

• When a formal speed restriction is detected along the road, the proactive speed adjustment function will also adapt the saved target speed in the background, even if the primary speed limiter is not actively switched on.
• If your actual vehicle travel speed considerably exceeds the speed limit detected by the road signal recognition system, a prominent warning message is shown on the instrument cluster display to alert you.
• When merging onto a high-speed motorway or dual carriageway, the recommended highway speed is automatically stored as your desired target speed.

Special cases

On dedicated motorway entry slip roads and exit lanes, your Seat Leon system temporarily stops applying strict maximum permitted speed regulation automatically, ensuring you retain optimal manual control in line with changing road layouts and surrounding traffic conditions.

Troubleshooting

A message is displayed indicating that proactive speed adjustment is not currently available or not offered in your country.

• If this notification message remains displayed on your screen for an extended period of time and proactive speed adjustment is officially supported in your region, please contact an authorized specialist workshop for diagnosis.

Note Depending on the exact nature of the detected system anomaly, supplementary diagnostic information may be displayed under Vehicle status in the infotainment menu.
