Problem
Possible causes/consequences and P Solutions
The engine is not running
smoothly and is misfir-
ing. There is am alfunction in the engine electronics or in am echanical
componen toft he engine management system.X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. X
Have the cause rectified immediately at aq ualified specialist work-
shop.
The coolant temperature
gauge shows av alue
above 248 ‡( 120 †).
The coolant warning
lamp may also be on and
aw arning 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 235). Observe the warning notes
as you do so and add coolant if necessary.
If the coolant level is correct ,t he engine radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled sufficiently. 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 moun-
tainou st errai na nd stop-and-go traffic.
DYNAMIC SELEC Tb uttonUse the DYNAMIC SELECT button to change the
drive program. Depending on the drive program
selected the following vehicle characteristics

the availability of the ECO start/stop function
Each time you start the engine with the Smart-
Key or the Start/Stop button, drive program C is
activated. For further information about starting
the engine, see ( Y

Press DYNAMIC SELECT button C as many
times as necessary until the desired drive
progra miss elected.
The selected drive progra ma ppears in the

Workin gint he engine compartment poses a
risk of injury.
Where possible, let the engine cool down and
touch only the component sd escribed in the
following.
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 ar isk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
Example X
Park the vehicle on al evel surface.
Only check the coolant level when the vehicle
is on al evel surface and the engine has cooled
down. X
Turn the SmartKey to position H in the igni-
tion lock ( Y
page 116).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice ( Y
page 116).X
Check the coolant temperature gage in the
multifunction display.
The coolant temperature must be below
158 ‡( 70 †).X

R
seals R
trim R
ventilation slots
Damaged seals or electrical component sc an
lead to leaks or failures.
! Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
! Do not affix: R
stickers R
films R
magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit aq ualified specialist workshop.X
Remove dirt immediately ,w here possible,
while avoiding rubbing too hard. X
Soak insect remains with insect remover and
rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse off
the treated areas afterwards. X
Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid. X
Use tar remover to remove tar stains. X
Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz .T his is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull ,t he paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot. X
Use as uitable touch-up stick, e.g. MB Touch-
Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally. Matt ef inish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following can give the paint ag lossy
appearance and thus reduce the matt effect: R
Rubbing hard with unsuitable agents R
Washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically ,tos hiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Only use automatic car washes which cor-
respond to the latest technological stand-
ards. Never use wash programs which finish
by treating the vehicle with hot wax.
Observe these notes if your vehicle has ac lear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
ac lear matte finish.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the decorative film
! The following may have an effect on the ser-
vice life and coloring of decorative film: R
sunlight R
temperature, e.g. hot-air fan R
weather conditions R
stone impacts and dirt R
chemical cleaning agents R
greasy substances
! Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it as hiny finish.
! Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.240
