G
WARNING
If you connect equipment to a diagnostics
connection, it can affect the operation of the
vehicle systems. This could compromise the
operating safety of your vehicle while driving.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection. G
WARNING
Loose equipment or cables hanging from a
device which are connected to a diagnostic
connection could impede pedal clearance.
The equipment or cables could get caught
between the pedals when driving and braking
suddenly. This could impair the function of the
pedals. There is a risk of accident.
Do not attach any equipment or cables in the
driver's footwell. !
If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring
information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop

In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Avoid the creation of sparks and
heat.
Avoid fire, naked flames and smok-
ing. Creation of sparks.
Battery acid is caustic.
Avoid contact with the skin, eyes
or clothing.
Wear eye protection.
Keep childre
naway. Observe this Owner's Manual.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at a qualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contac taquali-
fied specialist workshop.
Explosive gases are created during charging
and jump-starting.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz .These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
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 a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked up for a long period of time.
i
When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
i If the power supply has been interrupted,
e.g. due to a discharged battery, you will
have to:
R set the clock. Information on setting the
clock can be found in the separate oper-
ating instructions.
On vehicles with COMAND Online and a
navigation system, the clock is set auto-
matically.
R reset the head restraints on the front
seats (Y page 93).
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 100). 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 inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. Battery (vehicle)
