cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
i You must observe the legal requirements for
the country in which you are currently driving
when operating mobile communications
equipment in the vehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you may only do so if the traffic sit-
uation permits. You may otherwise be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus-
sion surrounding the 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 that mutual interference between the vehicle
electronics and mobile phones is minimised
An exterior aerial has the following advantages:
R it conducts the electromagnetic fields gener-
ated by a wireless device to the exterior
R the field strength in the vehicle interior is
lower than in a vehicle that does not have an
exterior aerial
Information on retrofitting two-way radios and
mobile phones (RF transmitters) (Y page 320).
General notes There are various mobile phone brackets that
may be fitted in your vehicle; in some cases,
these are country-specific.
You can connect a Bluetooth ®
-capable mobile
phone with COMAND Online through the Blue-
tooth ®
interface. This also applies if your vehicle
is equipped with convenience telephony. More information on suitable mobile phones,
mobile phone brackets and on connecting Blue-
tooth ®
-capable mobile phones with COMAND
Online can be obtained:

i The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Using a mobile phone If the mobile phone is inserted in the mobile
phone bracket, the mobile phone will be
charged and connected with the exterior aerial.
X Open the telephone compartment
(Y page 262).
X Place the mobile phone bracket into the pre-
installed fitting; see the separate installation
instructions for the mobile phone fitting.
X Insert the mobile phone into the mobile phone
bracket; see the separate installation instruc-
tions for the mobile phone fitting.
Operating the mobile phone You can operate the telephone using the
6
and ~ buttons on the multifunction steering
wheel. You can operate other mobile phone
functions via the on-board computer
(Y page 205).
When you remove the key from the ignition lock,
the mobile phone is disconnected from the
hands-free system. Active calls will first be
transferred to the mobile phone directly. Garage door opener
General notes The HomeLink

garage door opener integrated
in the rear-view mirror allows you to operate up
to three different door and gate systems.
Once programmed, the integrated garage door
opener in the rear-view mirror will assume the

when the vehicle is new or if you frequently drive
at high engine speeds.
Depending on the engine, the oil dipstick may be
installed at a different location.
When checking the oil level:
R park the vehicle on a level surface
R the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
R if the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait approximately 30 minutes before
carrying out the measurement
Checking the oil level using the oil dip-
stick 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. Example
X Pull oil dipstick :out of the oil dipstick tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide tube
to the stop, and take it out again.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =or
below, top up with 1.0 l of engine oil. Topping up engine oil 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. 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 does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the 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 service sys-
tem. You can obtain a list of the engine oils
and oil filters tested and approved in accord-
ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service Centre.
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 changing the engine oil and oil filter after
missing the change interval required by the
service system
R using engine oil additives
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off. 278
Engine compartmentMaintenance and care

Example: engine oil filler cap

The coolant temperature must be below
70 †.
X Turn the key to position 0(Y page 132) in the
ignition lock.
X Slowly turn cap ;half a turn anti-clockwise
to allow excess pressure to escape.
X Turn cap ;further anti-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank :.
If the coolant level is approximately 1.5 cm
above marker bar =in the filler neck when
warm, there is enough coolant in coolant
expansion tank :.
X If necessary, top up with coolant that has
been tested and approved by Mercedes-Benz.
