Interior filter: cleaning housing and re‐  
newing filter element  
Procedure  
Note  
Use a dust and pollen filter with at least an activated char‐  
coal layer, ideally an additional allergy filter layer.  
Pollen, soot, fine dust, unpleasant odours, ozone, nitrogen  
oxide and allergies can be filtered out effectively in this way.  
⇒ Heating, air conditioning; Rep. gr. 87; Front heater and air  
conditioning unit; Removing and installing dust and pollen filter.  
4.56  
Transportation mode: switching off  
Note  
The transportation mode is responsible for assuring the  
starting capability of vehicle.  
Battery discharging is reduced by the transportation mode,  
because electrical consumers are switched off.  
All vehicle functions which are not necessarily used during  
vehicle transportation and require no-load voltage or battery  
capacity are switched off with the activated transportation  
mode, with regard to the service life of battery.  
These are especially all functions in the vehicle which can  
reduce the battery capacity when being misused.  
Examples are radios, electronically operated flaps and at‐  
tachments and anti-theft alarm systems which can produce  
faults during transportation.  
– Switch transportation mode off/on ⇒ page 30 .  
4.57  
Transportation devices: removing  
blocking pieces  
Note  
On some models blocking pieces are fitted to the suspen‐  
sion strut piston rod.  
The blocking pieces prevent the springs compressing and  
possible damage to the vehicle when being driven onto a  
vehicle transporter or railway wagon.  
The blocking pieces must be removed without reservation  
before delivering the vehicle. A notice reading “Warning!”  
and attached to the interior rear view mirror highlights this  
point with absolute clarity.  
– Vehicles with blocking pieces fitted to the suspension struts  
have a label hanging from the mirror -arrow-.

Removing blocking pieces on piston rod  
– Relieve weight on coil springs by raising vehicle with a hoist.  
– Slide suspension strut protective sleeve -arrow- upwards.  
Note  
On the front axle, up to 3 blocking pieces are installed on  
each side.  
Usage of any auxiliary means for removal (such as lubricant  
spray, silicone or similar) is not permitted.  
– Push visible blocking piece -arrow- off piston rod.  
– Slightly press in bellows to sense the remaining blocking  
pieces. Slide them downwards on piston rod towards shock  
absorber cap using the folds of the bellows.  
– Push remaining blocking pieces off piston rod.  
– Check bellows -arrows- all-round for dents and rectify any  
dents.

– To rectify dents, slide bellows upwards, reach inside the  
bellows with your hand and press out the dents.  
– Check that bellows are properly engaged in axial bearing:  
♦ Correct position: bellows can be turned around rotational  
axis while seated in axial bearing.  
♦ Otherwise pull bellows all-round out of axial bearing by one  
notch.  
♦ After that, the bellows should be able to be turned around  
rotational axis.
