SEAT Leon Owner's Manual / Operating instructions / Driving / Acoustic parking aid system*

Rear parking aid

The parking aid system will use an acoustic signal to warn of the approach of any object towards the rear of the vehicle.

The acoustic parking aid system will measure the distance between the rear of the vehicle and any possible obstacle using four ultrasonic sensors located on the rear bumper. The measuring range of the sensors starts at approximately and depending on the nature of the obstacle at a distance of:

• side of the rear bumper: 0.8 m
• centre of the rear bumper: 1.3 m

The system is activated by engagement of the reverse gear. A brief acoustic signal confirms the activation and correct function of the system.

The distance warning will begin as soon as an obstacle is detected by the system. The frequency of the bleeps emitted by the system will increase rapidly as the vehicle approaches the obstacle.

Within a short distance of about 25 cm, a continuous signal sounds (stop signal). The driver should not reverse any further.

Trailer towing
For vehicles fitted with a tow bar by the manufacturer, the parking aid system will not be activated by the engagement of the reverse gear when pulling a trailer, as the trailer's electric connecter will be plugged into the vehicle.

To avoid system malfunctions, when not driving with a trailer, remove the trailer hitch.

Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is engaged, this indicates that there is a fault in the parking aid system.

If the fault continues until the ignition is turned off, the acoustic signal warning of the fault will not be emitted every time the system is reactivated (by engaging the reverse gear). Thus, the system ready indication will not sound either. Have the fault repaired by an Authorised Service Centre as soon as possible.

If there is no ready signal or no acoustic warning signal then the parking aid loudspeaker is faulty and may not warn of obstacles.

To ensure that the system works properly, the sensors must be kept clean and free of ice and snow.


• The sensors have blind spots in which obstacles may not be detected.
• Always look out for small children and animals because the system will not always detect them. Always pay attention when reversing to avoid accidents.
• The parking aid is not a replacement for driver awareness. The driver must take full responsibility for parking and other manoeuvres.

• Please note that low obstacles detected by the system may no longer be registered by the sensors as the car moves closer, so the system will not give any further warning. Certain kinds of obstacles (such as wire fences, chains, thin posts or trailer draw bars, high kerbs or painted railings etc) may not always be detected by the system, so there is a risk of damaging the vehicle in such cases.
• Obstacles with uniform edges and bumps may not be detected immediately by the system due to their geometry. Take special care around this type of obstacle such as corners, rectangular objects, etc.., these can cause damage to the vehicle.
• Be especially careful when manoeuvring into a corner between two perpendicular walls. Survey the approach of the wall to the side of the vehicle (using the mirrors)
• The parking aid system does not replace use of the mirrors for manoeuvres.

• Distant ultra-sonic sources (hammers, tyres, construction machinery, other vehicles with PDC) may interfere with the operation of the system.
• Periodic cleaning of the sensors, take care not to damage or scratch them.

When cleaning with high pressure washers or steam cleaners, the sensors should be sprayed for only a very short period and from a distance of more than 10 cm.

    The handbrake should always be firmly applied when the vehicle is parked. Always note the following points when parking the vehicle: – Use the foot brake to stop the vehicle. – Apply the handb ...
