Notes on noise or unusual handling charac‐
te rist ics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tires are damaged. If you suspect that a tire is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tires for dama ge. Hidden tire dam‐
age could also be causing the unusual handling
ch aracteristics. If youfind no signs of damage,
ha ve the tires and wheels checked at a qualified
specialist workshop.
Re gular checking of wheels and tires
0071
WARNING Risk of accident from dam‐
aged tires
Dama ged tires can cause tire pressure loss.
As a result, you could lose cont rol of your
ve hicle.
00BBCheck the tires regularly for signs of
dama geand replace any damaged tires
immediatel y.
0071
WARNING Risk of aquaplaning due to
insuf ficient tire tread
Insuff icient tire tread will result in reduced
tire grip. The tire tread is no longer able to
dissipate water.
This means that in heavy rain or slush the
ri sk of hydroplaning is increased, in particu‐
lar if vehicle speed is not adap tedto suit the
conditions.
If th e tire pressure is too high or too lo w,
tires may exhibit dif fere nt le vels of wear at
dif fere nt locations on the tire conta ct sur‐
fa ce.
00BBThus, you should regularly check the
tread de pth and the condition of the tire
conta ct surf ace across the entire width
of all tires.
Minimum tread dep thfor:
RSummer tires: 00CEin (3 mm)
RM+S tires: 00CFin (4 mm)
00BBFor saf etyre asons, replace the tires
before the legally prescribed limit for
th e minimum tread dep thisreached.
Car ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
RCheck the tire pressure (→page 354).
RVisual inspection of wheels and tires for
damage.
RCheck theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.
RVisual check of the tire tread dep thand the
tire contact surf ace condition across the
entire width.
