Parking Sensor System - Seat ALHAMBRA Owner's Manual

Parking sensor system*

Introduction
The parking sensor system assists the driver when parking. When the vehicle
approaches an obstacle, forwards or backwards, an intermittent sound will
be heard, higher or lower depending on the distance. The shorter the
distance, the shorter the intervals between tones. If the vehicle is too close to
the obstacle, the sound signal becomes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
The sensor system on the bumpers transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacle and recep-
tion), this system continuously calculates the distance between the bumper
and the obstacle.

WARNING
The parking sensor system and the optical parking system cannot replace
driver awareness.
The sensors have blind spots in which obstacles and people are not
registered.
Always observe the area around the vehicle, as the sensors do not
always detect small children, animals or objects.
The surface of certain objects and some clothing do not reflect the
ultrasound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these types
of clothes.

Operating instructions
WARNING (continued)
External sound sources can affect the parking distance aid signals. In
this case, under certain circumstances, people and objects will not be
detected.
Caution
The sensors may not always be able to detect objects such as trailer draw
bars, thin rails, fences, posts, trees and open luggage compartments, etc.
This could result in damage to your car.
Although the parking sensor system detects and warns of the presence of
an obstacle, the obstacle could disappear from the angle of measurement of
the sensors if it is too high or low and the system would no longer indicate it.
Therefore, it will not warn you of these objects. Ignoring the warnings of the
parking sensor system could cause considerable damage to the vehicle.
The bumper sensors may become damaged or misaligned, for example,
when parking.
To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.

When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray the sensors briefly at a distance of no less than 10 cm (4 inches).
Note
Acoustic sources may lead to erroneous warnings on the parking sensor
system, e.g. rough tarmac, cobbles or the noise of other vehicles.
