If the exterior lamp switch is set toU,

the headlamps may switch off unexpect-
edly when the system senses bright
ambient light, for example light from
oncoming traffic.


the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others,
activate headlamps by turning exterior lamp
switch toB when driving or when traffic
and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toB with the
vehicle at a standstill. Switching fromU
toB will briefly switch off the head-
lamps. Doing so while driving in low ambient
lighting conditions may result in an acci-
dent.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle's lights at all
times.

Turn the SmartKey in the starter switch to
position1 or2.

Call up the trip odometer and main
odometer by pressing buttonè
orÿ on the multifunction steering
wheel (
page 112).

Press buttonj ork until the
coolant temperature display appears.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.
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.
iExcessive coolant temperature triggers
a warning in the multifunction display.

Instrument cluster
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 111).

If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel until the trip odometer appears
(page 112).

Press and hold the reset button on the
instrument cluster (
page 22) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
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 23). For
information on how to select the unit of the
indicated temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
(
page 125).
!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.

110 Controls in detailInstrument clusterThe 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.

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 13.5 m) every second.
