Diagnostics connection
The diagnostics connection is used for connect- ing diagnostic equipment at a qualified special-
ist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. Qualified specialist workshop
A qualified specialist workshop has the neces-
sary special skills, tools and qualifications to
correctly carry out any necessary work on your
vehicle. This particularly applies to work rele-
vant to safety.
Observe the notes in the Service Booklet. Always have the following work carried out at a
qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conversions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about vehi-
cle checks if it has your registration data.
It is possible that your vehicle has not yet been
registered in your name in the following cases:
R if your vehicle was not purchased at an
authorised specialist dealer
R if your vehicle has not yet been inspected at a
Mercedes-Benz Service Centre
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle owner-
ship. You can do this at a Mercedes-Benz Ser-
vice Centre, for example. Correct use
If you remove any warning stickers, you or oth-
ers could fail to recognise certain dangers.
Leave warning stickers in position.
Observe the following information when driving
your vehicle:
R the safety notes in this manual
R the vehicle technical data
R traffic rules and regulations
R laws and safety standards pertaining to motor
vehicles Implied warranty
! Follow the instructions in this manual about
the proper operation of your vehicle as well as Operating safety

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 intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further informationcan be obtained at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre. ASSYST PLUS
237Maintenance and care Z

Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion.
Fire, naked flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes and clothing.
Wear suitable protective clothing; in
particular, gloves, an apron and a
face mask.
Immediately rinse electrolyte or acid
splashes off with clean water. Con-
sult a doctor if necessary. Wear eye protection.
Keep children at a safe distance.
Observe this Owner's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you use only batteries that have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the battery be damaged in the event of an accident.
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 ata qualified specialist workshop. You can also
charge the battery with a special 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.
If you use the key in the ignition lock and park
the vehicle, remove the key if you do not require
any electrical consumers. The vehicle will then
use very little energy, thus conserving battery
power.
If the power supply has been interrupted, e.g. if
the battery was discharged, you will have to:
R reset the function for automatically folding
the exterior mirrors in/out by folding the mir-
rors out once (Y page 85)
R reset the side windows (Y page 75) Charging the battery
Vehicles with a lithium-ion battery:
! Only use battery chargers with a maximum
charging voltage of 14.4 V.
All other vehicles 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. 252
