safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steerin gand the brake boostin
geffect. You will require considerably

ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in term
sofconsumption ,taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influenc ethe vehicle's consumption.
The ECO display consists of three bars:
R Acceleration
R Constant
R Coasting
The percen tvalue is th eaverage value of the
three bars .The three bars and the average
value commence with avalue of 50%. Ahigher
percentage indicates amoree conomical driv-
ing style.
The ECO display provides no information on
the actual fue lconsumption. Afixed percent-
age value of the ECO display does not corre-
spon dtoaf ixed consumption figure in
l/100km.
Apar tfromd rivin gstyle, consumption is
dependent on many factors such as:
R load
R tyre pressure
R cold start
R selected route
R number of consumer sthat are switched on Driving tips

If it is permitted by law to operate communi-
cations equipment whilet
he vehicle is in
motion, you must only do so if the traffic sit-
uationp ermits.Otherwise, yo ucould be dis-
tracted fro mthe traffi cconditions ,cause an
accident and injure yourself and others.
Two-way radios and fa xequipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronic sand thereby
jeopardise the operatin gsafety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
WARNING
Excessiv elevels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
int oa ccoun tcurren tscientific discussions
relatin gtothe possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronic sand mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.

tem may be damaged.
R in vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be fitted securely dur-
ing operation.
In order for the battery to achieve the maxi-
mum possibles ervice life, it must always be
sufficiently charged.
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 aqualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contact aquali-
fied 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 a
lengthy period. Consult aqualified specialist
workshop if you wish to leave your vehicle
parked up for along 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 After an interruption of the power supply,
e.g. the battery was discharged, you 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.
