Flat tyre

Notes on flat tyres
& WARNING Risk of accident due to a flat
tyre
A flat tyre strongly impairs the vehicle's driv‐
ing characteristics, as well as its steering and
braking characteristics.
Do not drive with a flat tyre.
#
Replace the flat tyre with the spare
#
wheel. Alternatively, consult a qualified
specialist workshop.
You will find a sticker with the Mercedes-Benz
Service24h telephone number on the B-pillar on
the driver's side, for example.
For vehicles with a spare wheel, information in

battery carried out at a qualified specialist work‐
shop.
& WARNING Risk of an accident due to
work carried out incorrectly on the bat‐
tery
Work carried out incorrectly on the battery
can, for example, lead to a short circuit. This
can restrict functions relevant for safety sys‐
tems and impair the operating safety of your
vehicle.
