The compass is calibrated in the factory in order to compensate

for deviations caused by magnetic field intensity of the vehicle and

magnetic interference when operating the heated rear window.

Once the compass is calibrated, it never needs to be recalibrated

under normal operating conditions. If a strong deviation in magnetic

field intensity is detected, the compass automatically recalibrates

itself.

A calibration must be carried out if the compass is replaced.
Additionally, the user can fine tune the compass in order to adapt

it to the vehicle's surrounding area. By setting the respective

compass zone, the compass compensates for deviations in the

earth's magnetic field.

The calibration should take place at least 10 m from any source of
interference such as power lines, buildings and parked vehicles.

MODEL
163

The convenience control allows the driver to operate the electrical

seat adjustment, the power windows, the electric vent windows, the

electric outside rearview mirror as well as the electric sliding/pop-up

roof or the electric lamella sliding roof

when the ignition is switched

off.

To achieve this, the all-activity module (AAM) (N10) switches to the

corresponding loads via the convenience relay (F1k14)

circuit 30 .

As of 12.99 the vehicle is equipped with its own convenience relay for

seat adjustment (relay 1, F2k1). In addition the status of the

convenience control via CAN is transmitted to the extended activity

module (EAM, N10/1).

Conditions for control actuation

On all-activity module (AAM) (N10) configured for

I
up

to

11.99:

The convenience actuation becomes active as soon as

D
Circuit 15 ON is recognized

When circuit 15 is switched off, the convenience actuation is

deactivated after a door is opened
Otherwise

The convenience actuation is active in the following cases:
D
Circuit 15c ON

D
A front door is open

D
The remote control key is removed, however, the doors are not

yet opened

In both cases the convenience actuation remains active for 5 min.

Switch-on condition for circuit 15c

When the remote control key is inserted into the ignition lock, circuit

15c is switched on when the key is turned out of the zero position.

Circuit 15c switches off only after the remote control key is removed

from the ignition lock
