Warning
The operating safety of your vehicle could be jeopardized if maintenance work is carried out
incorrectly. As a
result, you could lose control of the vehicle and cause an accident. In addition,
the safety systems may no longer be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop. The qualified
specialist workshop must have the necessary specialist knowledge and tools to carry out the
work required. We recommend visiting an authorized Sprinter Dealer. In particular, work relevant
to safety or on safety-related systems must be carried out at a qualified specialist workshop. Problem Possible causes/consequences and
