This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Read the information on qualified
specialist workshops: (Y page 24).
Important safety notes
G
WARNING
The driver's concentration must always be
directed primarily at road traffic.
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 only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second.
G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R
speed
R
outside temperature
R
warning/indicator lamps
R
malfunction/warning messages
R
failure of any systems
Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on the vehicle. Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages.
G
WARNING
All categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.
Failure to repair the condition noted may
cause damage not covered by the Mercedes-
Benz Limited Warranty, or result in property
damage or personal injury.
For an illustration of the instrument cluster,

Displaying the coolant temperature
G
WARNING
Driving when your engine is 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 which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
!
A display message is shown if the coolant
temperature is too high.
Displays and operation
205
On-board computer and displays
Z
If the coolant temperature is over
248 ‡(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gauge is in the
instrument cluster on the right-hand side
(Y page 205).
Under normal operating conditions and with
the specified coolant level, the coolant
temperature may rise to 248 ‡ (120 †).
Tachometer
!
Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
The outside temperature display is in the
multifunction display (Y page 207).
Changes in the outside temperature are
displayed after a short delay.
Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
R
Cruise control activated (Y page 168):
The segments light up from the stored
speed to the maximum speed.

The red coolant
warning lamp comes on
while the engine is
running.
The coolant level is too low.
!
Avoid making long journeys with too little coolant in the engine
cooling system. The engine will otherwise be damaged.
If the coolant level is correct, the airflow to the engine radiator
may be blocked or the electric engine radiator fan may be
malfunctioning.
The coolant is too hot and the engine is no longer being cooled
sufficiently.

Leave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
X
Check the coolant level and add coolant, observing the warning
notes (Y page 285).
X
If you need to add coolant more often than usual, have the
engine coolant system checked.
X
Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
X
Do not start the engine again until the coolant temperature is
below 248 ‡(120 †). Otherwise, the engine could be damaged.

The coolant temperature has exceeded 248 ‡ (120 †). The
airflow to the engine radiator may be blocked or the coolant level

WARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.
