ingly.

plays malfunctions and warnings from certain systems. For this reason, you should always
make sure that your vehicle is safe to use. You

tby driving
an unsafe vehicle. G

jeopardised if maintenance wor kis carried
out incorrectly. As aresult, you could lose
control of the vehicle and cause an accident.
In addition, the safety systems may no longer
be able to protec tyou or others as they are
designed to do.

a qualified specialist workshop. The qualified
specialist workshop must have the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work

tems must be carried out at a qualified spe-
cialist workshop. Displays and operation
