Instrument cluster illumination
Use the reset button1 to adjust the illu-
mination brightness for the instrument
cluster.
Warning!
G
If the instrument cluster or the multifunction
display, or both, are inoperative or malfunc-
tioning, warning messages will not be re-
layed when potential danger exists. This
may cause you and others to be unaware of
certain risks and/or personal injury.
Contact the nearest authorized
Mercedes-Benz Center as soon as possible.
iThe instrument cluster illumination is
dimmed or brightened automatically to
suit ambient light conditions.
The instrument cluster illumination will
also be adjusted automatically when
you switch on the vehicle’s exterior
lamps.

To brighten illumination
Turn the reset button1 in the instru-
ment cluster clockwise.
The instrument cluster illumination will
brighten.
To dim illumination
Turn the reset button1 in the instru-
ment cluster counterclockwise.
The instrument cluster illumination will

Coolant temperature indicator
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 odome-
ter display (
page 153).
If it is not displayed, press button è
or ÿ repeatedly until the trip
odometer appears.
Press and hold the reset button1
(page 150) until the trip odometer is
reset.
Warning!
G
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 and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
iExcessive coolant temperature trigger

152 Controls in detailInstrument clusterTachometer
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.
Outside temperature indicator
The outside temperature is displayed in
the instrument cluster (
page 24).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. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
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.
!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.
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
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
position1. 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

play, and much more.
The control system relays information to
the multifunction display.

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.

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 (
