PTS is activated automatically when
you switch on the ignition. PTS is deacti-
vated when the speed exceeds 15 km/h.
The Parktronic system is reactivated when
the vehicle's speed falls below this.
PTS monitors the area around your vehicle
using six sensors in the front bumper and
four sensors in the rear bumper.

Pay particular attention to objects above or
below sensors when parking, such as flower pots
or trailer towbars. PTS does not detect such
objects when they are in the immediate vicinity.
You could otherwise damage the vehicle or
objects.
Sources of ultrasonic waves, such as a lorry's
compressed-air brakes or a pneumatic drill could
cause PTS to malfunction.
