has already been programmed, indicator
lamp : will only start flashing yellow at a
rate of once a second after ten seconds
have elapsed.
XRelease button ;, = or ?.Features255Stowage and featuresZ

XPoint remote control A at a distance of
2 to 8 inches (5 to 20 cm) at buttons ;
to ? on the rear-view mirror.
i
The required distance between remote
control A and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be
necessary. You should test every position
for at least 25 seconds before trying
another position.
XPress and hold button B on remote control
A until indicator lamp : lights up green.
If indicator lamp : lights up green or
flashes, then programming has been
successful.XRelease button B on remote control A for
the garage door drive system.

XRepeat the programming 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.
i If the indicator lamp flashes green after
successful programming, the garage door
system is operating on a rolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronizing the rolling code
Your vehicle must be within reach of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
Observe the safety notes when performing
the rolling code synchronization
( Y page 254).
XTurn the SmartKey to position 2 in the

Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers are
designed to "time-out" in the same manner.
Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps

Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check the transmitter frequency of garage
door drive remote control A. This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280 to 390MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood that garage door remote control
A will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button that you are programming. Try
various angles at a distance between
2 and 12 inches (5 to 30 cm) or at the same
angle but at varying distances.
R If another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control A.
R Note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button B on remote control
A again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening/closing the garage door

Engine oil
Notes on the oil level
Depending on the driving style, the vehicle
consumes up to 0.9 US qts (0.8 l) of oil over
a distance of 600 miles (1,000 km). The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
AMG vehicles: before operation on race
tracks, check the oil level and ( Y page 261)
add oil if necessary (Y page 262). Race track
operation is only permitted with a maximum
engine oil level.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
Checking the oil level using the oil
dipstickXPull oil dipstick : out of the dipstick guide
tube.XWipe off oil dipstick :.XSlowly 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.XIf the oil level is at or below MIN mark =,
add 0.55 US qt to 1.1 US qt ( 0.5 to 1.0 l) of
engine oil.Engine compartment261Maintenance and careZ

Adding engine oilGWARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
