Check tires on all wheels
 Check tread as well as outer and inner 
sidewalls on all tires for signs of damage such 
as cuts, punctures, cracks, breakouts, 
separation and ingressed foreign matter. If 
damage is present

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: 
#
Determine cause for increased tire wear and 
rectify, then:

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.

Closing sliding /pop-up roof, function

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.
