Information on noise or unusual driving
ch aracteristics
While driving, pay attention tovibrations, noises
and unusual driving characteristics, e.g. pulling to
one side. This may indicate damage tothe wheels
or tires. If you suspect that a tire is defective,
re duce your speed. Stop theve hicle as soon as
possible tocheck if wheels and tires ha vebeen
damaged or are no longer functioning properly.
Hidden tire damage could also be causing the
unusual driving characteristics. If no signs of
damage can be de tected, ha vethe tires and

WARNING Risk of accident from dam‐
aged tires
Dama ged tires can cause tire pressure loss.
As a result, you could lose control of your
ve hicle. #
Check the tires regularly for signs of
dama geand replace any damaged tires
immediatel y. Check
the wheels and tires of your vehicle for
damage regular ly, i.e. at least every two weeks,
as well as af ter driving off-road or on rough
ro ads. Damaged wheels can lead toa loss of tire
pressure.
Look out forth efo llowing types of damage, for
ex ample:
R cuts in the tires
R punctures in the tires
R tears in the tires
R bulges on tires
R deformation or se vere cor rosion on wheels &
WARNING Risk ofhydroplaning because
tire tread is too low
Insuf ficient tire tread will result in reduced
tire traction. The tire tread will no longer be
able todissipate water.
This increases therisk of hydroplaning on wet
ro ad sur faces, pa rticularly when tra veling at
an inappropriate speed. If

may exhibit dif fere nt le vels of wear at dif fer‐
ent locations on the tire tread. #
