11 Using the parking aid
The rear sensors (MWE820, 860) are activated automatically by engaging the
reverse gear with the ignition on or the engine running. The speaker will emit a
double beep.
The front sensors (MWE890) are automatically activated as soon as the ignition is
switched on and the speed of the vehicle lies between 0 and around 15 km/h.
As an option, instead of being connected to the speed signal, the control electronics
of the front sensors can be connected to the reversing light or an external switch.

The sensors are active in the following cases:
• For around 30 seconds after the motor is started
• When the reverse gear is engaged and the control electronics are connected to
the reversing light
• For around 30 seconds after the reverse gear is disengaged
• The sensors can be activated with an external button (accessory) for a duration of
around 30 seconds.
As soon as there is an obstacle within the detection range, a repeated signal tone is
emitted.
As you approach, the tone sequence and the flashing frequency change, depending
on the zone in which the obstacle is, thus indicating the distance (fig. d).
MWE860 (optional MWE890): The nearer the obstacle gets, the more LEDs light
up on the display.

NOTE
Before using either of these functions, hold down the button on the
control electronics for 2 seconds (see chapter “Restoring the factory
settings” on page 10).
NOTICE!
Stop the vehicle immediately and investigate the situation (getting out if
necessary), if the following happens while you are manoeuvring:
when manoeuvring, the device first indicates an obstacle and the tone
sequence speeds up normally (e.g. from slow to medium). Suddenly the
signal tone slows down, or no obstacle is indicated at all.
This means that the original obstacle is in the blind spot of the sensors
(construction-related characteristic), and it is possible to hit it.
