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 nearest
authorized Mercedes-Benz Center.
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 contact 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.

H
(USA only)
Combination low tire
pressure/TPMS malfunction tell-
tale for the TPMS illuminates
continuously.
(Canada only)
Low tire pressure telltale for the
Advanced TPMS* illuminates
continuously.
The TPMS (USA only) or Advanced TPMS*
(Canada only) 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 situa-
tion around you.

Read and observe messages in the
multifunction display (
page 356).
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.
H
(USA only)
Combination low tire
pressure/TPMS malfunction tell-
tale for the TPMS flashes for
60 seconds and then stays illu-
minated.
There is a malfunction in the TPMS.

Read and observe messages in the
multifunction display (
page 356).

Have the TPMS checked by an
authorized Mercedes-Benz Center.
After the malfunction has been remedied
the combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.

352 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.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.

(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 (

If 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 (

356 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 141) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 26) or
buttonj, k, è orÿ on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button or buttonj,
k, è orÿ on the multifunction
steering wheel. They are then stored in the
vehicle status message memory
(
page 153). Remember that clearing a
message will only make the message
disappear. Clearing a message will not
correct the condition that caused the mes-
sage to appear.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated,
addressed 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
divided into two sections:

Text messages (
page 358)


Symbol messages (
page 370)
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, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.

Switching on the ignition causes all
instrument cluster lamps (except high beam
headlamp indicator lamp and turn signal indica-
tor lamps unless activated) as well as the multi-
function display to come on. Make sure the
lamps and multifunction display are in working
order before starting your journey.
