Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you,
take the SmartKey with KEYLESS-GO* with
you and lock the vehicle. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
If the vehicle was previously centrally
locked with the SmartKey or the
SmartKey with KEYLESS-GO*, it will
not unlock using the central unlocking
switch2.
If the vehicle was previously locked
with the central locking switch1:
While in the global remote control
mode, the vehicle is unlocked com-
pletely when a door is opened from
the inside.
While in the selective remote con-
trol mode, only the door opened
from inside is unlocked.
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.
