When indicator lamp :lights up green: pro-
gramming is finished.
When indicator lamp :flashes green: pro-
gramming was successful. The next step is to synchronize the rolling code (
Ypage 229).
XRelease button Bon remote control Afor
the garage door drive system.
If indicator lamp :lights up red: repeat the
programing procedure for the corresponding
button on the rear-view mirror. When doing so, vary the distance between remote control
A
and the rear-view mirror.
The required distance between remote con-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attemptsm ight be necessary. You
should test every position for at least
25 seconds before trying another position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Ypage 228).
If the garage door system uses arolling code,
you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you will
need to use the programming button on the door
drive control panel. The programming button
may be located in different places depending on
the manufact

urer. It is usually located on the
door drive unit on the garage ceiling.
Familiarize yourself with the garage door drive
operating instructions, e.g. under "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 116).

drive unit.
Usually,y ou now have 30 seconds to initiate
the next step.
XGet into the vehicle.
XPress previously programed button ;,=
or ? on the integrated garage door opener
repeatedly until the door closes.
The rolling code synchronization is then com-
plete.
Notes on programming the remote con-
trol
Canadianr adio frequency laws require a"break"
(or interruption) of the transmission signals
after broadcasting for afew seconds. Therefore,
these signals may not last long enough for the
integrated garage door opener. The signal is not
recognized during programming. Comparable

Adding engine oil
GWARNING
Certain components in the engine compart-
ment ,such as the engine, radiator and parts
of the exhaust system, can become very hot.
Workingint he engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
If engine oil comes into contact with hot com- ponentsint he engine compartment ,itmay
ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck.L et the engine cool down and
thoroughly clean the engine oil off the com-
ponentsb efore starting the engine.
HEnvironmenta lnote
When adding oil, take care not to spill any. If
oil enter sthe soil or waterways, it is harmful to
the environment.
!Use only engine oils and oil filters that are
approved for vehicles with aservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordanc ewith
Mercedes-Benz Specifications for Service
Products is availableata ny authorized
Mercedes-Benz Center. The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of 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.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick ,add 1.1 US qt (1.0 liter) of
engine oil.
XReplace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely.
XCheck the oil level again with the oil dipstick
(Ypage 234).

Workinginthe engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the componentsd escribed in the
following.
GWARNING
The cooling system is pressurized, particularly
when the motor is warm. If you open the cap,
you could be scalded if hot coolant sprays out.
There is arisk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Slowly
open the cap to relieve pressure.
Example
XPark the vehicle on alevel surface.
Only check the coolant level when the vehicle
is on alevel surface and the engine has cooled
down.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 116).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (
Ypage 116).
XCheck the coolant temperature gage in the
multifunction display.
The coolant temperature must be below
158 ‡(70 †).
XTurn the SmartKey to position u
(Ypage 116) in the ignition lock.
XSlowly turn cap :half aturn anti-clockwise
to allow excessp ressure to escape.
XTurn cap;further counter-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 0.6 in
(1.5 cm
)above marker bar =in the fuel filler
neck when warm, there is enough coolant in
expansion tank :.
XIf necessary, add coolant that has been tested
and approved by Mercedes-Benz.
XReplace cap;and turn it clockwise as far as
it will go.

Specia lservice requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account .Under arduous operating condition sor
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example:
Rregular cit ydrivingw ith frequent intermediate
stops
Rif the vehicle is primarily used to travel short
distances
Ruse in mountainous terrain or on poor road
surfaces
Rif the engin eisoften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eoil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at aqualified specialist workshop, e.g.
