Problems with the 115 V power socket
Problem
Possible causes/consequences and
M
MSolutions The warning lamp on
the 115 V power socket
is not lit. The on-board voltage is too low because the battery is too weak.
X Start the engine.
or
X Charge the battery (Y page 430).
If the indicator lamp still does not light up:
X Visit a qualified specialist workshop. The temperature of the DC/AC converter is temporarily too high.
X Remove the electronic device connector from the 115 V socket.
X Let the DC/AC converter cool down.
If the indicator lamp still does not light up after cooling down the
converter: X Visit a qualified specialist workshop. You have connected an electronic device that has a constant
nominal power of less than 150 watts, but has a very high switch-
on current. This device will not work. If you connect such a device, the 115 V power socket will not supply it with power.
X Connect a suitable electronic device. Coolbox in the rear compartment
Important safety notes G
WARNING
If you cover the ventilation grille for the cool-
box, it may overheat. There is a risk of fire.
Always make sure that the ventilation grille is not covered.
The ventilation grille for the coolbox is in the
trunk.
The coolbox can bear a maximum load of
7.7 lb (3.5 kg).
If you want to store a bottle in the upper com-
partment of the coolbox, the capacity of the
bottle must not exceed 17 fl. oz. (0.5 l).
Store only plastic bottles in the upper com-
partment of the coolbox. Using the coolbox

To open: pull handle :on the cover.
X Fold the cover out to the front.
X To switch cooling level to low: press but-
ton ;once.
An indicator lamp in the button lights up.
X To switch cooling level to high: press
button ;twice.
Both indicator lamps in the button light up.
X To switch off cooling: press button;
repeatedly until the indicator lamps go out.
The cooling output of the coolbox depends on
the ambient temperature and the selected
cooling level.
The coolbox reduces its cooling output or
switches off, if:
R many electrical consumers are turned on
R the starter battery is not sufficiently
charged
This is indicated by the flashing indicator
lamps in the button. The cooling function will automatically switch back on as soon as there is sufficient voltage.
Caring for the coolbox If you do not need to use the coolbox for an
extended period you should switch it off,
defrost it and clean it. After doing so, leave
the lid open for a time. Removing and installing the coolbox
You can remove the coolbox for maintenance
purposes.
X To remove: switch off the coolbox.
X Pull plug ;down and out.
X Unscrew both screws =.
X Pull out the coolbox.

Where possible, let the engine cool down and
touch only the components described in the
following. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a ser-
vice system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
center.
Damage to the engine or exhaust system is caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R replacing engine oil and oil filters after
the interval for replacement specified by
the service system has been exceeded
R using engine oil additives.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off. Example
X Turn cap :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 :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 405).

WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following. G
WARNING
The engine cooling system is pressurized, par- ticularly when the engine is warm. When 408

Comply with the important safety notes for
service products when handling brake fluid
(Y page 489).
The brake fluid change intervals can be found in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at

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.
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 not exceed 55% (antifreeze protection
do wn to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accord-
ance with
MB Specifications for Service 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.
