126 Controls in detailLightingManual headlamp mode
The low beam headlamps and parking
lamps can be switched on and off with the
exterior lamp switch. For exterior lamp
switch, see (
page 125).Automatic headlamp mode
The following lamps switch on and off au-
tomatically depending on the brightness of
the ambient light:


Low beam headlamps


Tail and parking lamps


License plate lamps


Side marker lamps.
iWith the SmartKey removed from the
starter switch or the engine turned off
with KEYLESS-GO* and the driver’s
door open, a warning sounds if the
parking lamps or low beam headlamps
are switched on.
The message
TURN OFF LIGHTS
appears in the multifunction display.
Warning!
G
If the exterior lamp switch is set toU,

the headlamps may switch off unexpect-
edly when the system senses bright am-
bient 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, acti-
vate headlamps by turning exterior lamp
switch to B when driving or when traffic
and/or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from position U to B with the
vehicle at a standstill. Switching from U
to B 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.iThe front fog lamps and rear fog lamp
cannot be switched on manually with
exterior lamp switch in positionU.
To activate the fog lamps, turn exterior
lamp switch to positionB and pull
the exterior lamp switch to first or sec-
ond stop (
page 128).

135 Controls in detail
Instrument cluster
Coolant temperature gauge
During severe operating conditions,
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to 248° F (120°C),
i.e. close to the red zone of the coolant
temperature gauge.
The engine should not be operated with
the coolant temperature above 248° F
(120°C), i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not cov-
ered by the Mercedes-Benz Limited War-
ranty.
Trip odometer
Make sure you are viewing the trip
odometer display.

If it is not displayed, press the è or
ÿ button on the multifunction
steering wheel repeatedly until the trip
odometer appears (
page 137).

Press and hold reset buttonJ in the
instrument cluster (
page 134) until
the trip odometer is reset.
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 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
(page 345).

136 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.
CL 55 AMG and CL 65 AMG
The tachometer of the CL 55 AMG and
CL 65 AMG does not have a red marking
denoting excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive engine speed.
Outside temperature indicator
The outside temperature is displayed in
the instrument cluster (
page 24). For in-
formation on how to select the unit of the
displayed temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
(
page 157).
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.
Clock
The time is indicated in the instrument
cluster in the tachometer display.
You can adjust the clock using the
COMAND system. Refer to separate
COMAND operating instructions.
!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.

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.

function steering wheel will alter what is
shown in the multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-
menus.
The individual functions are then found
within the relevant menu (radio or CD op-
erations under
AUDIO
