open. X
Stop the vehicle. Pay attention to the traffic
conditions as you do so.
X Close the bonnet. V At least one door is open. The display
symbol shows you which doors are open. X
Close the doors. D The cooling fan for the coolant is faulty. X
If the coolant temperature is less than 120 †,
you can continue driving to the nearest quali-
fied specialist workshop.
X In doing so, avoid heavy loads on the engine
(e.g. driving in mountainous terrain) and stop-
and-go driving. @ Vehicle rising

Troubleshooting
283Problem Possible cause/consequence Suggested solutions
The steering wheel heating* indi-
cator lamp on the lower left lever
of the steering column is flashing. There is insufficient voltage
because too many consumers are
switched on. The steering wheel
heating* has switched itself off
automatically. X
Switch off consumers that are not required, e.g. reading lamps,
interior lighting, etc.
The steering wheel heating* will automatically switch back on as
soon as there is sufficient voltage again. The indicator lamp in the
2
button on the Thermatic/4-zone
Thermotronic* control panel
flashes three times when you
press the button. The cooling sys-
tem cannot be switched on. Cooling has been deactivated
due to a malfunction. X
Visit a qualified specialist workshop. The indicator lamp in the
¯
rear-window heating button is
flashing. The rear-window heat-
ing has switched itself off prema-
turely or cannot be switched on. There is insufficient voltage
because too many consumers are
switched on. X
Switch off consumers that are not required, e.g. reading lamps,
interior lighting, etc.
The rear-window heating will automatically switch back on as soon
as there is sufficient voltage again. Vehicles with automatic child
seat recognition on the front-
passenger seat*:
The
5 PASSENGER AIRBAG
OFF warning lamp on the centre
console is lit. A special Mercedes-Benz child
seat with automatic child seat
recognition has been fitted to the
front-passenger seat. The front-
passenger airbag has therefore
been disabled. Practical advice

Risk of accident
Only have a trailer coupling retrofitted at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
! If you have a trailer tow hitch retrofitted,
changes to the cooling system may be nec-
essary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chas-
sis frame. Saloon

Service products and capacities
388 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 quantity of anti-
freeze protection. You could otherwise
damage the engine.
There is more information about coolant
and topping it up on Mercedes-Benz Spec-
ifications for Service Products Sheet
310.1.
! 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:
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 using an antifreeze/corrosion inhibi-
tor 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. Have the
renewal confirmed in the Service Booklet.
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
