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, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.
i
The 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.

Coolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(
page 24).
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 125).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 126) until the trip
odometer appears in the multifunction
display.
Press and hold the reset button in the
instrument cluster (
page 122) until
the trip odometer is reset.
Warning!G
Driving when your engine is badly
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.
!
Excessive coolant temperature triggers
a warning in the multifunction display
(
page 368).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by
the Mercedes-Benz Limited Warranty.
i
During severe operating conditions,
e.g. stop-and-go traffic, the coolant
temperature may rise close to 248°F
(120°C).

Tachometer
The red marking on the tachometer
(
page 24) denotes 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 indicated in the
multifunction display (
page 125).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 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
engine 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.

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,
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.
