Problems when programming
If you have problems when programming the
integrated remote control, please note the fol-
lowing:
RCheck the transmitter frequency used by
garage door drive remote control Aand
whetheritiss upported. The transmitter fre-
quency can usuall ybefound on the back of
remote control Afor the garage door drive.
The integrated remote control is compatible
with devicest hat have units which operate in
the frequency range of 280 to 390 MHz.
RReplace the batterie sinremote control A.
This increase sthe probability of remote con-
trol Asending astrong and precise signal to
the integrated remote control on the rear-
view mirror.
RWhen programming, hold remote control A
at varying distances and angle sfrom the
transmitter button that you are programming.
Try various anglesatad istance between2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control Ais available for
the same garage door drive, repeatt he same
programming steps with this remote control
A.B efore performing these steps, make sure
that new batterie shave been installed in
garage door drive remote control A.
RNote that some remote controls only transmit
foralimited amount of time (the indicator
lamp on the remote control goes out). Press
button Bon remote control Aagain before
transmission ends.
RAlign the antenna cabl eofthe garage door
opener unit. This can improve signal trans-
mission.

GWARNING
Opening the hood when the engine is over-
heated or when there is afire in the engine
compartment coul dexpose you to hot gases

Notes on the oil level
Depending on you rdriving style ,the vehicle
consumes up to 0.9 US qt (0.8 liters )ofoil per
600 mile s(1000 km). The oil consumption may
be higher than this whe nthe vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in ad ifferent location.
When checking the oil level:
Rpark the vehicle on alevels urface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine wa sonly started
briefly,w aita pproximately 30 minutes before
carrying out the measurement
Checking the oil level usingt he oil dip-
stick
Example: engine compartment
On the G63AMG, the oil levelc an be checked
using the oil dipstick.
XPul loil dipstick :out of the dipstick guide
tube.
XWipeo ff oil dipstick :.
XSlowly slide oil dipstick :into the guide tube
to the stop and take it out again after approx-
imately three seconds.
If the levelisb etween MIN mark =and MAX
mark ;,the oil levelisc orrect.
XIf the oil levelh as dropped to MIN mark =or
below, add 1.1 US qt (1.0 l)of engine oil.
On all other models, the on-board computer
must be used to check the engine oil level.
Checking the oil level using the on-
board computer
G5 50: the oil level can only be checked using
the on-board computer.
XMake sure that the SmartKey is in position 2
in the ignition lock.
XPress 9or: on the steering wheel to

Adding engine oil
!Use only engine oils and oil filters that are
approved for vehiclesw ithaservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any 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 specifiedbyt he
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 leadt o
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
HEnvironmental note
When adding oil, take care not to spilla ny. If
oil enters the soil or waterways ,itisharmful to
the environment.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd the amount of engine oil required.
Observe the specifications in the on-board com-
puter when doing so or fill carefully to the max-
imum mark on the oil dipstick.
The difference betweent he minimum mark and
the maximum mark on the oil dipstick is approx-
imatel y2.1 US qt (2.0 l).
XReplace cap :on the fille rneck and tighten
clockwise.
Ensur ethat the cap locks into place securely.

Checking coolant level
Checking the coolant level (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 104).
XCheck the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡(70 †).
XSlowlyt urn cap :half aturn counter-clock-
wise and allow excess pressure to escape.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the fillern eck 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 fillern eck
