315 Operation
Tires and wheels
For additional information on tire load
rating, see “Load identification”
(page 317).Tire speed rating
The tire speed rating6 (
page 313)
indicates the approved maximum speed
for the tire.
Warning!
G
The tire load rating must always be at least
half of the GAWR (
page 323) of your vehi-
cle. Otherwise, tire failure may be the result
which may cause an accident and/or seri-
ous personal injury to you or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.
Warning!
G
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard located
on the driver’s door B-pillar. Overloading the
tires can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
iTire load rating5 (
page 313) and
tire speed rating6 (page 313) are
also referred to as “service descrip-
tion”.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others. iTire load rating5 (
page 313) and
tire speed rating6 (page 313) are
also referred to as “service descrip-
tion”.

319 Operation
Tires and wheels
Tire type code
The code4 (
page 318) may, at the
option of the manufacturer, be used as a
descriptive code for identifying significant
characteristics of the tire.
Date of manufacture
The date of manufacture5 (
page 318)
identifies the week and year of manufac-
ture.
The first two figures identify the week,
starting with “01” to represent the first full
week of the calendar year. The second two
figures represent the year.
For example, “3202” represents the 32nd
week of 2002.
Maximum tire load
1Maximum tire load rating
The maximum tire load is the maximum
weight the tires are designed to support.For more information on tire load rating

340 Practical hintsWhat to do if …?Lamps in instrument cluster
General information:If any of the following lamps in the instru-
ment cluster fails to come on during the
bulb self-check when switching on theignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow Antilock Brake
System (ABS) indicator lamp
comes on while driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP
® are
also switched off (see messages in multi-
function display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*,
Distronic*, and the automatic transmission
may also be malfunctioning.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

Read and observe messages in the mul-
tifunction display (
page 353).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.
The battery may not be charged sufficiently.

Switch off electrical consumers that are
currently not needed, e.g. seat heat-
ing*.

If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value again,
the ABS is operational again.
