12.11 Air suspension

Do not clean air suspension components with steam cleaner or high-
pressure cleaner. Do not use any organic solvents or scouring agents.
Approved cleaning agents are mild soap, methanol, ethanol and isopro-
pyl alcohol.
Inspect the air suspension bellows periodically for damage and leaks.
When not in use for an extended period, the vehicle level may gradually be-
come lower. To prevent permanent deformation and damage to the bellows:
Support the vehicle with steady legs or fill the air suspension bellows with
compressed air once weekly.
12.12 Electrical ventilation system
If the aspired air is led into the open via an outlet in the door or in the floor,
change the inserted active carbon filter once a year. If the air is led into the
open via the roof, the ventilation system is maintenance-free.

Further information can be obtained in the manufacturer's instruction
manual.

 Every alteration of the original condition of the vehicle can alter road
behaviour and jeopardize road safety.
 The special equipment and original spare parts recommended by
HYMER GmbH & Co. KG have been specially developed and sup-
plied for your vehicle. These products are available at the authorised

formed about admissible technical details and carries out the required
work correctly.
 The use of accessories, parts and fittings not supplied by HYMER

road safety. Even if an expert's report, a general type approval or a
design certification exists, there is no guarantee for the proper quality
of the product.
 No liability can be assumed for damage caused by products which
have not been released by HYMER GmbH & Co. KG . This also ap-
plies to impermissible alterations to the vehicle.
For safety reasons, spare parts for pieces of equipment must correspond
with manufacturer's instructions and be permitted by the manufacturer as a
spare part. These spare parts may only be fitted by the manufacturer or an
