There could be a malfunction in the engine
electronics or in the fuel supply system.
Carry out the following steps:XIf you are starting the engine with the
SmartKey: Turn the SmartKey in the starter
switch to position  0 and repeat the starting
procedure.XIf you are starting the engine with KEYLESS-
GO: Close any doors that may be open to
allow for better detection of the SmartKey.
or
XStart the engine with the SmartKey as radio

XLet the starter cool for about 2 minutes.XRepeat the starting procedure.
If the engine does not start after several
starting attempts:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.Driving offGWarning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
!  Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service life
of the engine. This is not covered by the
Mercedes-Benz Limited Warranty.
Drive off immediately after starting the
engine to warm up the engine efficiently.
The engine must be at operating
temperature before using full engine
power. The engine has reached operating
temperature once the engine oil
temperature indicator in the AMG menu of
the control system has stopped flashing.
At engine temperatures below 32‡ (0†),
the engine’s maximum speed is restricted
in order to protect it from damage. Avoid
driving your vehicle at full speed when the
engine is cold to prevent premature engine
wear and/or diminished comfort.
!  You have forgotten to release the
electronic parking brake when driving off if
R an acoustic warning sounds
R the message  Release Parking Brake
appears in the multifunction display
R the red indicator lamp for the electronic
parking brake  0049 (USA only) or  0024

Release the electronic parking brake.
!  Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.

Instrument cluster
Introduction
For a full view illustration of the instrument
cluster, see “Instrument cluster”
( Y  page 34).
GWarning!
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.
The language setting for the multifunction
display can be changed via COMAND system
( Y  page 99).
Activating the instrument cluster
The instrument cluster is activated when you
R open the driver’s door
R switch on the ignition
R switch on the exterior lamps
Engine oil temperature gauge
The engine oil temperature gauge is located
in the instrument cluster. The engine oil
temperature may rise up to 140† under
normal driving conditions.
!  The engine should not be operated with
the engine oil temperature above 140†.
Doing so may cause serious damage which
is not covered by the Mercedes-Benz
Limited Warranty.
The temperature of the transmission fluid and
coolant are displayed in the AMG menu
( Y  page 287).
Tachometer
The red marking on the tachometer
( Y  page  34) denotes excessive engine speed.
!  Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
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 indicator is
displayed in the multifunction display
( Y  page 273).
GWarning!
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.
Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster  (Y  page  34). Once the fuel
level has fallen below the reserve mark, the
yellow fuel tank reserve warning lamp  00B8
for the fuel reserve comes on.

RACE START
RACE START enables optimum acceleration
from a standing start with suitable high-grip
road surface conditions.   
GWarning!
RACE START is only available when ESC
SPORT is activated. ESC SPORT only
stabilizes the vehicle to a certain extent if it is
swerving or the wheels are spinning.
RACE START may only be used on closed
roads. Always adapt your speed and driving
style to suit the current road and weather
conditions.
Conditions for activation
RACE START can be activated when
R the doors are closed
R the trunk is closed
R the hood is closed
R the engine is running and the transmission
and the engine have reached their
operating temperature. The engine has
reached its operating temperature when
the engine oil temperature indicator in the
multifunction display stops flashing.

! To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel may
reach the catalytic converter, causing it to
overheat and potentially start a fire.
i Only use premium unleaded gasoline with
a minimum Posted Octane Rating of 91
(average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump. Please
contact gas station personnel in case
labels on the pump cannot be found.
For more information on gasoline, see
“Premium unleaded gasoline”
( Y  page 425), see “Fuel requirements”
( Y  page 427), or contact an authorized
Mercedes-Benz Center, or visit
http://www.MBUSA.com  (USA only).
Locking/unlocking the vehicle with the
SmartKey automatically locks/unlocks the
fuel filler flap.
i In case the central locking system does
not release the fuel filler flap, or the

Roadside Assistance or an authorized
Mercedes-Benz Center.
The fuel filler flap is located on the right-hand
side of the vehicle towards the rear.   XTurn off the engine.i Leaving the engine running and the fuel
filler cap open can cause the yellow engine
malfunction indicator lamp  00BB to
illuminate.

This could cause the hood to come loose and
injure you and/or others.
Opening
GWarning!
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature display to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department.
GWarning!
You could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions.
GWarning!
