Check tire wear pattern on all wheels

Greater wear at the shoulder compared to

the center of the tire is normal for the front

wheel tires. Wear on the rear tires is uniformly

distributed across the total tread, whereby

wear on vehicles with rear-wheel drive in the
middle of the tread is somewhat greater than

at the shoulders. In event of unusual tire

pattern:

Measure the depth of tread of the tires on al

the wheels and note the measurement in the

table on the maintenance sheet.

Measure depth of tread at point of

greatest wear. Perform measurement at

outside, inside and center of tread.

Minimum depth of tread 1.6 mm.

For safety reasons, tires should be

replaced before the minimum depth of tread is

reached:

D
Summer tires for approx. 2 to 3 mm depth

of tread

D
Winter tires at approx. 4 mm depth of tread

Change round wheels on front and rear axles
If necessary, and only on vehicles without

mixed tires

Retain running direction of wheels, as
otherwise handling performances and comfort

may be impaired and tire wear increased.

MODEL
163 with CODE (414a) Electric glass sliding/pop-up roof

Function prerequisites

D
Voltage not too low or too high

D
Switch-on conditions for convenience control fulfilled

Function

The sliding roof and pop-up roof can be closed by pressing the

switch (SR, S13/2)
. The sliding/pop-up roof can only be closed by

continuously pressing the
switch (SR, S13/2)
.

The express close function is not available for safety reasons.


If the sliding/pop-up roof has not been synchronized, it opens only in

the pop-up roof direction each time the
switch (SR, S13/2) is

actuated. Upon reaching its end position, i.e. before the pop-up roof

is completely open,
synchronization
is accomplished.
After successful synchronization, the sliding/pop-up roof can then be

controlled without limitations.

Vehicles
up to 11.99:

The power for the
sliding/pop-up roof (M12)
is supplied via a

fuse directly to c. 30.

The power for the
switch (SR, S13/2)
is supplied via the

convenience relay (F1k14)
, which is actuated by the
all-activity

module (AAM, N10)
.

Vehicles
as of 12.99:

The power for the
sliding/pop-up roof (M12)
is supplied via a

fuse directly to c. 30. The power for the
switch (SHD, S13/2) is

supplied via a lead to the
extended-activity module (EAM,

N10/1) , this power is switched through only when the switch-on

conditions for the convenience control are fulfilled and the EAM is

coded accordingly.

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.

Zone setting

1
Press the MODE button on the trip computer

until the compass direction is displayed

2
Press the RESET button once

The current compass zone is displayed

3
Press the RESET button until the desired

compass zone is displayed

The maps for determining the correct

compass zone can be found in the owner's

manual. If the RESET button is not pressed

within 5 seconds, the point of the compass is

displayed again.

The calibration mode is active and remains

active until the calibration process has

concluded. If the ignition is switched off and

on, calibration mode remains active, even if
CAL
no longer is displayed.

km/h.

Calibration process concluded.

Although the display can change from
CAL
to

the point of the compass before the

calibration drive has been concluded, the

calibration process is still active and must be

carried out exactly as described.

Convenience control, function
7.4.97

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
