The yellow roll bar warning lamp
comes on or flickers when the
engine is running.
The roll bar system is malfunctioning.
For safety reasons, always have the roll
bar raised when driving with the retract-
able hardtop open.
Attempt to raise the roll bar manually
(page 81).

Have the roll bar checked by an au-
thorized Mercedes-Benz Center as
soon as possible.
Warning!
G
If the roll bar warning lamp does not come
on, does not go out after a long time, flickers
or comes on while driving as described
above, then the roll bar system is not oper-
ating properly and may not activate in an
accident. In this case, raise the roll bar man-
ually (
page 81) before continuing to drive.

The red seat belt telltale comes
on and a warning chime sounds
for approximately 6 seconds
after starting the engine with all
doors closed.
The seat belt telltale reminds you and your
passengers to fasten your seat belts before
driving off.

Fasten your seat belts.
The seat belt telltale goes out.

The red seat belt telltale remains
illuminated after driving off. The
vehicle’s speed does not exceed
15 mph (25 km/h).
You and/or your front passenger have
forgotten to fasten your seat belts.

Fasten your seat belts.
There are items placed on the front passen-
ger seat and therefore the system senses the
front passenger seat as being occupied.

Remove the items from the front
passenger seat and put them in a safe
place.

The red seat belt telltale flashes
and you additionally hear an in-
termittent warning chime with in-
creasing intensity for a maximum
of 60 seconds from the time the
vehicle’s speed exceeds 15 mph
(25 km/h).
You and/or your front passenger have

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 Center.
Warning!
G
In the event that a malfunction of the SRS is
indicated as outlined above, the SRS may
not be operational. For your safety, we
strongly recommend that you visit an
authorized Mercedes-Benz Center immedi-
ately to have the system checked; otherwise
the SRS may not be activated when needed
in an accident, 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.

USA only:
Combination low tire pressure/
TPMS malfunction telltale for
the TPMS illuminates continu-
ously.
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 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
combination low tire pressure/TPMS mal-
function telltale goes out after few minutes
driving.

USA only:
Combination low tire pressure/
TPMS malfunction telltale 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 mul-
tifunction display.

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.

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 underinflated tire causes the tire to over-
heat and can lead to tire failure.
Underinflation 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 underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
USA only:
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.

Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear in the in the multifunction display lo-
cated 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 152) 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 26) or but-
ton j, 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 or button j, k,
ÿ, or è on the multifunction steer-
ing wheel. They are then stored in the vehi-
cle status message memory (
page 152).
Remember that 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, 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 (

No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative. Contact your nearest au-
thorized Mercedes-Benz Center.
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, do so with
added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.

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