passenger’s seat belt (with the passenger
seat occupied) is not fastened with both
doors closed,
R the seat belt telltale 7 remains
illuminated for as long as either the driver’s
or passenger’s seat belt is not fastened.
R and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a
maximum of 60 seconds or until the
driver’s and passenger’s seat belt are
fastened.
If you and/or your passenger release the
seat belt during driving, the seat belt
telltale 7 starts flashing and the
warning chime sounds as described before.
If the driver’s or the passenger’s seat belt
remains unfastened after 60 seconds, the
warning chime stops sounding, the seat
belt telltale 7 stops flashing but
continues to be illuminated.
After a vehicle standstill, the warning chime
is reactivated and the seat belt telltale
7 is flashing again if the vehicle speed
once exceeds 15 mph (25 km/h).
The seat belt telltale 7 will only go out if
both the driver’s and the passenger’s seat
belt (with the passenger seat occupied) are
fastened, or the vehicle is standing still and a
door is opened.
For more information, see “Practical hints”
( Y page 256).
Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts are equipped with ETDs and
seat belt force limiters.
The ETDs are designed to activate in the
following cases:
R in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R if the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” ( Y page 38)
R in certain vehicle rollovers if the system
determines an additional degree of
protection
The ETDs will only activate if the seat belts are
fastened (latch plate properly inserted into
buckle).
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit
more snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
i The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest.GWarning!
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center.
Automatic comfort-fit feature seat belt
The automatic comfort-fit feature reduces the
retracting force of the seat belts when they
are in normal use.

dangers, deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in
unconsciousness and death.
! When you open the trunk, the trunk lid
swings open upwards. Always make sure
there is sufficient overhead clearance.
You can open the trunk when the vehicle is
stationary and the retractable hardtop is fully

GWarning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†).
! Excessive coolant temperature triggers a
warning in the multifunction display and the
red coolant temperature warning
lamp ? in the instrument cluster comes
on.
The engine should not be operated with a
coolant temperature above 248‡ (120†).

Control system
Introduction
The control system is activated as soon as the
starter switch is in position 1.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to set the language for
messages in the instrument cluster display,
and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display.
Multifunction steering wheel
