Bonnet
Important safety notes G
WARNING
An unlocked bonnet may open up when the
vehicle is in motion and block your view. There is a risk of an accident.
Never unlock the bonnet when driving. Before
every trip, ensure that the bonnet is locked. G
WARNING
When being opened and closed, the bonnet
may suddenly fall into the closed position.
There is a risk of injury to persons in the range of movement of the bonnet.
Open and close the bonnet only when nobody
is in the range of movement. G
WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade. G
WARNING
There are moving components in the engine
compartment. Certain components may con-
tinue to move or suddenly move again even
after the ignition has been switched off, e.g.
the radiator fan. There is a risk of injury.
If you have to carry out work in the engine
compartment:
R switch off the ignition
R never touch the dangerous areas surround-
ing moving components, e.g. the rotation
area of the fan R
remove jewellery and watches
R keep items of clothing and hair, for exam-
ple, away from moving parts. G
WARNING
The ignition system and the fuel injection sys- tem operate with a high voltage. If you touch
the live components, you could receive an
electric shock. There is a danger of injury.
Never touch components of the ignition sys-
tem or the fuel injection system when the
ignition is switched on.
Active bonnet (pedestrian protection) Operating principle
! A triggered active bonnet must be repaired
at a qualified specialist workshop. The active bonnet function will then be available again.
The additional pedestrian protection provided by the active bonnet will then be restored.
The active bonnet is available only for certain
countries.
The active bonnet can reduce the risk of injury to
pedestrians in certain accident situations. Rais- ing the active bonnet increases the clearance tohard components, such as the engine.
If the active bonnet has been triggered, it is
raised at the rear in the area around the hinge byapproximately 60 mm.
For the drive to the workshop, reset the trig-
gered active bonnet yourself. If the active bon-
net has been triggered, pedestrian protection
may be limited.
Resetting G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. 302

Depending on the operating conditions of the
vehicle, the remaining time or distance until the
next service due date is displayed.
The letter indicates which service is due. A A
stands for a minor service and B
Bfor a major ser-
vice. A number or another letter may be dis-
played after the letter.
For certain countries only: the position after the
letter A Aor B
Bindicates any necessary additional
maintenance work. If you notify a qualified spe-
cialist workshop of this display, you will receive a statement on the associated costs.
The ASSYST PLUS service interval display does
not take into account any periods of time during
which the battery is disconnected.
Maintaining the time-dependent service sched-
ule:

the multifunction display before disconnect-
ing the battery.
or
X After reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display. Hiding service messages

Resetting the ASSYST PLUS service
interval display !
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in the Service Booklet. This may otherwise lead
to increased wear and damage to the major
assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special service requirements The prescribed service interval is based on nor-
mal operation of the vehicle. Service work will
need to be performed more often if the vehicle is
operated under arduous conditions or increased loads, for example:
R Regular city driving with frequent intermedi-
ate stops
R If the vehicle is primarily used to travel short
distances
R For frequent use in mountainous terrain or on
poor road surfaces
R If the engine is often left idling for long periods
R In particularly dusty conditions, or if air-recir-
culation mode is frequently used.
In these or similar operating conditions, have
the interior filter, engine air cleaner, engine oil
and oil filter, for example, changed more fre-
quently. The tyres must be checked more fre-
quently if the vehicle is operated under
increased loads. Further information can be
obtained at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any Mercedes-Benz
Service Centre. ASSYST PLUS
307Maintenance and care Z

In order for the battery to achieve the maximum
possible service life, it should always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle. In such cases, have the battery disconnected at
a qualified specialist workshop. However, you
can also charge the battery with a charger rec-
ommended by Mercedes-Benz. For more infor-
mation, please contact a qualified specialist
workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for an exten- ded period. Consult a qualified specialist work-
shop if you wish to leave your vehicle parked up
for a long period of time.
When you park the vehicle, remove the key if you do not require any electrical consumers. The
vehicle will then use very little energy, thus con- serving battery power.
If the power supply has been interrupted, e.g. if
the battery was discharged, you will have to:
R set the clock using the multimedia system;
see the separate operating instructions
R reset the function for folding the exterior mir-
rors in/out automatically, by folding the mir-
rors out once (Y page 113) Charging the battery
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maximum
charging voltage of 14.8 V.
! Only charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment (Y page 325).
X Open the bonnet.
X Connect the battery charger to the positive
terminal and earth point in the same order as
when connecting the donor battery in the
jump-starting procedure (Y page 325).
If the indicator/warning lamps do not light up in
the instrument cluster at low temperatures, it is very likely that the discharged battery has fro-
zen. In this case, you may neither jump-start the vehicle nor charge the battery. The service life of
a battery that has been thawed may be reduced. The starting characteristics may be impaired,
especially at low temperatures. Have the
thawed battery checked at a qualified specialistworkshop.
Only charge the installed battery with a battery
charger which has been tested and approved by Mercedes-Benz. A battery charger unit specially
adapted for Mercedes-Benz vehicles and tested and approved by Mercedes-Benz is available as
an accessory. This device permits charging of
the battery while it is installed. Contact a
Mercedes-Benz Service Centre for information
and availability. Read the battery charger's
operating instructions before charging the bat-
tery. 324
