Problem
Possible causes/consequences and P Solutions
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system. X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. X
Have the cause rectified immediately at a qualified specialist
workshop.
The coolant tempera-
ture gauge shows a
value above 248 ‡
(120 †). The coolant
warning lamp may also
be on and a warning
tone may sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently. X
Stop as soon as possible and allow the engine and the coolant to
cool down. X
Check the coolant level ( Y
page 311). Observe the warning
notes as you do so and add coolant if necessary.
DYNAMIC SELECT button (all vehicles
except Mercedes-AMG vehicles)
Use the DYNAMIC SELECT button to change
the drive program. Depending on the drive
program selected the following vehicle char-
acteristics will change: R
the drive (engine and transmission man-
agement) R
the steering R
the availability of the ECO start/stop func-
tion R
the climate control:
Each time you start the engine with the
SmartKey or the Start/Stop button, drive pro-
gram C is activated. For further information
about starting the engine, see ( Y
page 151). X
Press DYNAMIC SELECT button C as many
times as necessary until the desired drive
program is selected.
The selected drive program appears in the
multifunction display. After five seconds
the display goes out and the status icon of
the selected drive program appears.
In addition, the current drive program set-
tings are displayed briefly in the Audio 20 or
COMAND display.
i In a few countries, the ECO start/stop
function is deactivated at the factory due to
the available fuel grade. In this case, the
ECO start/stop function is not available in
any drive program, regardless of the display
in the Audio 20 or COMAND display.DYNAMIC SELECT button (all vehicles except Mercedes-AMG vehicles) 157

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 engine is limited within a range to protect
the engine when the red band is reached.
Outside temperature display You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul-
tifunction display ( Y
page 221).
There is a short delay before a change in out-
side temperature appears in the multifunc-
tion display.
Coolant temperature display
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
! A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side
( Y
page 31). Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †).

Problem
Possible causes/consequences and P SolutionsX
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 311). X
If you have to add coolant frequently, have the engine cooling
system checked. X
Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice. X
At coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop. X
Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic.
Driving systems
Problem
Possible causes/consequences and P Solutions

Example: engine oil cap X
Turn cap C counter-clockwise and remove
it. X
Add engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 l) of
engine oil. X
Replace cap C on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely. X
Check the oil level again with the oil dip-
stick ( Y
page 310).
Further information on engine oil
( Y
page 379).
Checking and adding other service
products
Checking coolant level
G WARNING
The cooling system is pressurized, particularly
when the motor is warm. If you open the cap,
you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
! The coolant may only be checked and cor-
rected when the engine is cool (coolant
temperature below 104 ‡ (40 †). Check-
ing the coolant when the coolant tempera-
ture is above 104 ‡ (40 †) may result in
damage to the engine or to the engine cool-
ing system. Example X
Park the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the engine has
cooled down. X
Turn the SmartKey to position 2 in the igni-
tion lock ( Y
page 149). X
Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
104 ‡ (40 †). X
Turn the SmartKey to position 0 in the igni-
tion lock ( Y
page 149). X
Slowly turn cap C counter-clockwise and
to relieve excess pressure. X
Turn cap C further counter-clockwise and
remove it.
If the coolant is at the level of marker bar

Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet. Comply with the important safety precautions
for service products when handling coolant
( Y
page 377).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks: R
corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡( -37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †) .R
no t exceed 55 % (antifreeze protection
do wn to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends coolant or anti-
freeze/corrosion inhibitor concentrate in
accordance with MB Specifications for Ser-
vice Products 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked with every main-
tenance interval at a qualified specialist
workshop.
