Information on driving
R If the vehicle is heavily loaded, chec kthe
tire pressures and correct them if neces-
sary.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- cate that the wheels or tires are damaged.If you suspect that atire is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tires checked at aqualified specialist workshop.

Observe the notes in the "Changing awheel"
section (Y page 270). Drivin
gwiths ummer tires
At temperatures below 45 ‡(+7† ), summer
tires experience aconsiderable loss in elas-
ticity and therefore traction and braking
power. Change the tires on you rvehicle to
M+S tires. Using summe rtires at very cold
temperatures coul dcause cracks to form,
thereb ydamaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
00CF in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7† ), use win-
ter tires or all-season tires. Both type softire
are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possibl egrip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. Thi sisbecause
these tires were specifically developed for
driving in snow.
Use M+S tires of the same make and tread on
allw heels to maintain safe handling charac-
teristics.
Always observe the maximu mpermissible
spee dspecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressure s(Ypag e253).
X Restart the tire pressure monitor
(Y pag e259). 252
