1
The red SRS indicator lamp
comes on while driving.
There is a malfunction in the restraint sys-
tems. The air bags or Emergency Tensioning
Devices (ETDs) could deploy unexpectedly or
fail to activate in an accident.

Drive with added caution to the near-
est authorized Mercedes-Benz Cen-
ter.
Warning!
G
In the event a malfunction of the SRS is indi-
cated as outlined above, the SRS may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in an
accident and/or injury to you or to others.

Low tire pressure telltale for the
Advanced TPMS* illuminates
continuously.
The Advanced TPMS* detects a loss of
pressure in at least one tire.

Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic situation
around you.

Read and observe messages in the mul-
tifunction display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
low tire pressure telltale goes out after few
minutes driving.

392 Practical hintsWhat to do if …Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly under-inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.

(USA only)75The indicator lamp illuminates and remains
illuminated with the weight of a typical adult
or someone larger than a small individual on
the front passenger seat.
The system is malfunctioning.

Have the system checked as soon as
possible by an authorized
Mercedes-Benz Center.

Read and observe messages in the
multifunction display and follow cor-
rective steps (
page 403).
Warning!

If the

indicator lamp
illuminates and remains illuminated with the
weight of a typical adult or someone larger

ger seat, do not have any passenger use the
front passenger seat until the system has
been repaired.

(USA only)75The indicator lamp does not illuminate
and/or does not remain illuminated
with the weight of a typical
12-month-old child in a standard child
restraint or less on the front passenger
seat.
The system is malfunctioning.

Make sure that there is nothing between seat cush-
ion and child seat and check installation of the child
seat.

Make sure that no objects applying supplemental
weight onto the seat are present.

Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged behind or around the seat, head
restraints pushing against roof etc.). The system
may recognize such forces as supplemental weight.

If the light remains out, have the system checked as
soon as possible by an authorized Mercedes-Benz
Center. Do not transport a child on the front passen-
ger seat until the system has been repaired.

Read and observe messages in the multifunction
display and follow corrective steps (
page 403).

rized Mercedes-Benz Center as soon as
possible.

396 Practical hintsWhat to do if …Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 151) displays both cleared and
uncleared messages.
High-priority messages appear in the mul-
tifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 148) or
buttonj, k, ÿ or è on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display us-
ing the reset button (
page 148) or
buttonj, k, ÿ or è on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 164). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.

On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may ap-
pear in the multifunction display.
For your convenience the messages are di-
vided into two sections:

Text messages (
page 398)


Symbol messages (
page 411)
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.i
Switching on the ignition causes all instru-
ment cluster lamps (except low beam headlamp
indicator lamp, high beam headlamp indicator
lamp, and turn signal indicator lamps unless ac-
tivated) as well as the multifunction display to
come on. Make sure the lamps and multifunction
display are in working order before starting your
journey.
