SEAT Leon 3 coding: hidden features

Windows after ignition off

After switching off the engine you can still operate the windows for a while, as long as no door has been opened.

CodingLikely possibleModules: 09 Central Electrics

Automatic summer and winter time

The car clock switches to summer and winter time by itself. No more setting it by hand.

Start-stop – remember last setting

Makes the car remember whether you switched start-stop off, so you do not have to press the button every trip. We agree the setting in the workshop.

CodingLikely possibleBy agreementModules: 19 Data Bus On Board Diagnostic Interface, 09 Central Electrics

We agree the exact setting with you in the workshop.

Service interval setting

After maintenance we reset the service indicator and set the right interval, fixed or flexible.

Towbar coding after fitting

After a towbar is fitted we code the car so trailer lights, ESC trailer stabilisation and parking sensors work together properly.

CodingLikely possible

For a retrofit towbar it depends on the wiring kit.

Condition: Towbar fitted (factory or retrofit)

Cornering lights via the fog lamps

When turning at low speed the fog lamp on the inside of the bend lights up, so you see kerbs and cyclists better.

Daytime running lights – with rear lights

During the day the rear lights come on together with the daytime running lights, so you are seen better in poor visibility. We agree the exact setup.

CodingLikely possibleBy agreementModules: 09 Central Electrics

We agree the exact setting with you in the workshop.

Condition: LED or bulb rear lights; result differs per light type

High-beam assistant release or memory

With a front camera the car switches between low and high beam by itself. On newer models the assistant can stay on after every start.
