Important safety notes
Up to three different door and gate systems
can be operated using the remote control
integrated in the overhead control panel.
i Certain garage door openers are not
compatible with the integrated remote
control. If you experience difficulties with
the programming of the integrated remote
control, contact an authorized Mercedes-
Benz Center or call the following telephone
assistance service:
R USA:  Mercedes-Benz Customer
Assistance Center on
1-800-FOR-MERCedes
R Canada:  Customer Service
on1-800-387-0100
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.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. 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. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and possible death.

Adding engine oilHEnvironmental note
When adding 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 which
have been approved for vehicles with a
service system. A list of the engine oils and
oil filters that have been tested and
approved according to the Mercedes-Benz
specifications for service products can be
found on the Internet at http://
www.mbusa.com (USA only). Further
information on tested and approved engine
oils and oil filters can be obtained from any
authorized Mercedes-Benz Center.
The following causes engine failure or
damage to the exhaust system:
Rusing engine oils and oil filters that are
not specifically approved for the service
system
Rreplacing the engine oil and oil filter later
than the specified replacement interval
required by the service system
Rusing engine oil additives
Example: engine oil cap
XTurn cap : counter-clockwise and remove
it.
XAdd the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
iThe difference in quantity between the
MIN mark and the MAX mark on the
dipstick is (depending on the engine)
approximately 1.6 to 2.1 US qt. (1.5 to 2 l).
! 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
converter. Have excess oil siphoned off.
Further information on engine oil
(Y page 337).
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
Checking and adding other service
products
Checking the coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position
2(Y page 151) in the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 151).
XCheck the coolant temperature display in
the instrument cluster.
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 pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The

then remain illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is lit, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
i If the tire pressure monitoring system
malfunctions, it may take up to 10 minutes
before the malfunction is displayed to you
by the tire pressure warning lamp flashing
for 60 seconds and then remaining lit.
When the error has been rectified, the tire
pressure warning lamp goes out after a few
minutes of driving.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tire pressure of each
tire is shown in the multifunction display.
i The tire pressure values in the on-board
computer may deviate from the inflation
pressure as measured using a tire pressure
checker at the filling station. The tire
pressures shown in the on-board computer
refer to pressures at sea level. At high
altitudes, a tire pressure checker will
display a higher tire pressure than the on-
board computer. In this case do not reduce
the tire pressure.
i If radio transmitting equipment (e.g. radio
headphones, a two-way radio) is operated
in or near the vehicle, this can lead to the
function of the tire pressure monitor being
impaired.i This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
1. This device may not cause harmful
interference, and
2. This device must withstand any
interference received, including
