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 129).
Press and hold reset button on the in-
strument cluster (
page 22) 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 306).
128 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
The tachometer of the CL 55 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 22). 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 148).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 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.

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, we recommend that you
pull over to a safe location and stop before
making or taking a telephone call. If you
choose to use the telephone while driving,
please use the hands-free device and only
use the telephone when weather, road and
traffic conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
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.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and / or
personal injury.

Automatic transmission
Automatic transmission
For more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
page 45).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current op-
erating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by adjust-
ing its gear shift program.The automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever positionD with
gear ranges (
page 159)
the selected shift program (C/S)
(page 163)
or
(C/S/M) (CL 55 AMG only)
(page 164)
the position of the accelerator pedal
the vehicle speed
The current gear selector lever position
and shift program (
C/S) or (
C/S/M) appear
in the tachometer display (
page 22).When the gear selector lever is in
positionD, you can influence transmission
shifting by:
limiting the gear range
changing gears manually
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
It is dangerous to shift the gear selector le-
ver out of P or N if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or reverse. You could
lose control of the vehicle and hit someone
or something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
