Garage door opener
The integrated remote control can operate up
to three separately controlled devices
compatible with HomeLink ®
 or some other
systems.
GWarning!
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.

The following will result in engine or
emission control system damage not
covered by the Mercedes-Benz Limited
Warranty:
RUsing engine oils and oil filters of
specification other than those expressly
required for the Maintenance System.
RChanging of oil and oil filter at change
intervals longer than those called for by
the Maintenance System.
RUsing any oil additives.
XUnscrew oil filler cap \000F with integrated oil
dipstick.
XAdd engine oil as required. Be careful not
to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
! Excess oil must be siphoned or drained
off. It could cause damage to the engine
and emission control system not covered
by the Mercedes-Benz Limited Warranty.
XScrew filler cap \000F back on filler neck.
Make sure the filler cap engages.
For more information on engine oil, see the
“Technical data” section (Y page 425) and
(Y page 426).
Transmission fluid level
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an
authorized Mercedes-Benz Center check the
transmission.
Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the
coolant temperature must be below 158‡
(70†).
GWarning!
In order to avoid any potentially serious burns:
RUse extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
RDo not remove the cap on the coolant
expansion tank if the coolant temperature
is above 158‡ (70†). Allow the engine to
cool down before removing the cap. The
coolant expansion tank contains hot fluid
and is under pressure.
RUsing a rag, slowly open the cap
approximately  1/2  turn counterclockwise
to relieve excess pressure. If opened
immediately, scalding hot fluid and steam
will be blown out under pressure.
RDo not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.

and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 11
 while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND 11
 (Cockpit
Management and Data System) if road,
weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet.
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Maintenance
Notes
The Maintenance System in your vehicle
tracks the distance driven and the time
elapsed since the last maintenance service.
It calculates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center. Have it serviced in accordance
with the Maintenance Booklet at the times
called for by the maintenance service
indicator.
i Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
Maintenance service indicator

Information on maintenance work and
maintenance intervals are specified in the
