SEAT Leon Owner's Manual / Tips and Maintenance / Driving and the environment / Trailer towing / What do you need to bear in mind when towing a trailer?

Your vehicle may be used to tow a trailer when fitted with the correct equipment.

If the car is supplied with a factory-fitted towing bracket it will already have the necessary technical modifications and meet the statutory requirements for towing a trailer. For the after-market fitting of a trailer towing bracket.

Your vehicle is fitted with a 12-pin connector for the electrical connection between the trailer and the vehicle.

If the trailer has a 7-pin plug you will need to use an adapter cable. This is available from any SEAT dealer.

Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to the maximum permitted trailer weight, you can then climb correspondingly steeper gradients.

The maximum trailer weights listed are only applicable for altitudes up to 1,000 m above sea level. With increasing altitude the engine power and therefore the vehicle's climbing ability are impaired because of the reduced air density. The maximum trailer weight has to be reduced accordingly. The weight of the vehicle and trailer combination must be reduced by 10% for every further 1,000 m (or part thereof). The gross combination weight is the actual weight of the laden vehicle plus the actual weight of the laden trailer.

Where possible, operate the trailer with the maximum permitted draw bar weight on the ball joint of the towing bracket, but do not exceed the specified limit.

The figures for trailer weights and draw bar weights that are given on the data plate of the towing bracket are for certification purposes only. The correct figures for your specific model, which may be lower than these figures for the towing bracket, are given in the registration documents􀂟 Section “Technical data”.

Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as possible. Loads carried in the trailer must be secured to prevent them moving.

Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in accordance with the trailer manufacturer's recommendations.

Exterior mirrors
Check whether you can see enough of the road behind the trailer with the standard mirrors. If this is not the case you should have additional mirrors fitted. Both exterior mirrors should be mounted on hinged extension brackets. Adjust the mirrors to give sufficient vision to the rear.


Never transport people in a trailer. This could result in fatal accidents.

• Towing a trailer places additional demands on the vehicle. We recommend additional services between the normal inspection intervals if the vehicle is used frequently for towing a trailer.
