Inf Infor ormation on noise or unusual dr mation on noise or unusual driving c
t t er eris istics tics
While driving, pay attention to vibrations, noises
and unusual driving characteristics, e.g. pulling to
one side. This may indicate damage to the wheels
or tires. If you suspect that a tire is defective,
reduce your speed. Stop the vehicle as soon as
possible to check if wheels and tires have been
damaged or are no longer functioning properly.
Hidden tire damage could also be causing the
unusual driving characteristics. If no signs of dam-
age can be detected, have the tires and wheels
checked at a quali ed specialist workshop.

ARNING Risk of injury through damaged

tires

Damaged tires can cause tire pressure loss.
Check the tires regularly for signs of
#
damage and replace any damaged tires
immediately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two weeks, as
well as a er driving o -road or on rough roads.
Damaged wheels can lead to a loss of tire pres-
sure.
Look out for the following types of damage, for
example:
Cuts in the tires
R
Punctures in the tires
R
Tears in the tires
R
Bulges on tires
R
Deformation or severe corrosion on wheels

& W W ARNING
ARNING Risk of hydroplaning due to
insu cient tire tread
Insu cient tire tread will result in reduced tire
grip.
Thus, you should regularly check the
#
tread depth and the condition of the
tread across the entire width of all tires.
Minimum tread depth for:
Summer tires: â in (3 mm)
R
M+S tires: ã in (4 mm)
R
For safety reasons, replace the tires
iving char harac- ac-
#
before the legally prescribed limit for the
minimum tread depth is reached.
Conduct the following checks regularly on all
wheels, at least once a month or as required, e.g.
before a long journey or when driving o -road:
Check the tire pressure (
R
Check the valve caps
R
Valves must be protected from moisture and
dirt with valve caps speci cally approved by
Mercedes-Benz for your vehicle.
Visually inspect the tread depth and the tire
R
tread across the whole tire width
The minimum tread depth for summer use is
â in (3 mm) and for winter use ã in (4 mm).
Markings
tors (arrow) are integrated into the tire tread. They
are visible as soon as the tread depth is approx-
imately á in (1.6 mm).
Inf Infor ormation on dr mation on driving wit
At temperatures below 50 °F (10 °C) summer tires
lose elasticity and therefore traction and braking
power. Change the tires on your vehicle to M+S
tires. Using summer tires at very cold tempera-
tures could cause tears to form, thereby damaging
the tires permanently. Mercedes-Benz cannot
accept responsibility for this type of damage.
Always observe the maximum permissible speed
speci ed for the summer tires you have installed
( page 210).

Once you have installed the summer tires:
Check the tire pressure (
