X Make sure, that the air supply to the radiator
is not blocked, e.g. by slush.

Pull over and stop the vehicle safely and switch
off the engine, paying attention to road and
traffic conditions.
X Check the poly-V-belt.
X If the poly-V-belt is torn: do not continue
driving. Consult a qualified specialist work-
shop.
X If the poly-V-belt is not damaged: do not
start the engine again until the display mes-
sage disappears. Otherwise, there is a risk of
engine damage. B Top up coolant See
Owner's Manual The coolant level is too low. X
Top up the coolant, observing the warning
notes before doing so (Y page 175).
X If the coolant needs topping up more often than
usual, have the engine coolant system checked
at a qualified specialist workshop. 3 Power steer. mal-

Risk of accident
There is no power assistance for the steer-
ing. You will need to use more force to
steer.
The steering assistant STEER CONTROL is
also deactivated. X
Check whether you are able to apply the extra
force required.
X If you are able to steer safely: carefully drive
on to a qualified specialist workshop.
X If you are unable to steer safely : do not drive
on. Contact the nearest qualified specialist
workshop. Practical advice

Troubleshooting
234 Problem Possible cause/consequence Suggested solutions
Vehicles with a petrol engine:
The engine is not running
smoothly and is misfiring. There is a malfunction in the
engine electronics or a mechani-
cal component of the engine con-
trol unit. X
Onl y depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist work-
shop.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. A coolant temperature of over
120 °C is displayed. The coolant
warning lamp may also be on and
a warning tone may sound
(Y page 97). The coolant level is too low. The
coolant is too hot and the engine
is no longer being cooled suffi-
ciently. X
Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 175). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the
radiator fan may be faulty. The
coolant is too hot and the engine
is no longer being cooled suffi-
ciently. X
If the coolant temperature is less than 120 °C, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Practical advice

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Owner's Manual in the relevant chapter
since:
R parts and service products are matched
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as you could other-
wise endanger yourself and others.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Before refuelling, always turn off the
engine. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health.

Engine oils for vehicles without a diesel
particle filter may also be used temporarily in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.

Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec-
tion. !
Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. You could otherwise damage the
engine.
More information on coolant and refilling
can be found in the Mercedes-Benz Speci-
fications for Service Products, sheet no.
310.1 and is available from any Mercedes-
Benz Service Centre. !
Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 °C.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should: Technical data

R
be at least 50%. This will protect the cooling
system against freezing down to around –
37 °C.
R not exceed 55% concentration (antifreeze
protection down to –45 °C); otherwise,
heat will not be effectively dissipated.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The cooling system contains a filling
which must be renewed after 15 years, or
after 250, 000 km at the latest.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz, and
observe the recommended mixing ratios. Technical data
