Warning
G
Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can
cause serious burns an can occur just by
opening the hood. Stay away from the
engine if you see or hear steam coming
from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Instrument cluster
During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Make sure you are viewing the trip
odometer display (
page 127).
If it is not displayed, press the j or
k button on the multifunction
steering wheel repeatedly until the trip
odometer appears.
Press and hold reset button4
(page 22) until the trip odometer is
reset.
Tachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
SL 55 AMG
The tachometer of the SL 55 AMG does not
have a red marking denoting excessive en-
gine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive speed.
!Excessive coolant temperature triggers
the coolant temperature warning lamp
(page 304) and a warning in the
multifunction display (
page 286).
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

126 Controls in detailInstrument clusterOutside temperature indicator
The outside temperature is displayed in
the right multifunction display
(page 22). For information on how to se-
lect the unit of the displayed temperature,
i.e. degrees Celsius (°C) or degrees Fahr-
enheit (°F), see “Selecting temperature
display mode” (
page 140).The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next the sensor, not
by comparison to external displays, e.g.
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an Ice-Warning Device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

Control system
Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO start/stop button is in posi-
tion 1. The control system enables you to
call up information about your vehicle
change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, and much more.
The control system relays information to
the multifunction display.
Multifunction display
The multifunction display consists of the
display fields in the speedometer and the
tachometer. In its default state, the left
display field shows the trip and main
odometer, while the present outside tem-
perature appears in the right display field.
This default setting is referred to as the
standard display.

Warning!
G
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, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit 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 (approximate-
ly 14 m) every second.

Malfunction and warning messages are only
indicated for certain systems and are inten-
tionally not very detailed. The malfunction
and warning messages are simply a remind-
er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Center to address the malfunction and
warning messages (
page 291).
iThe message memory will be cleared
when you switch on the ignition. You
will then only see high priority malfunc-
tions (
