X Repeat the programming procedure. When
doing so, change the distance between the
garage door's remote control and the trans-
mitter buttons in the rear-view mirror.
i If the garage door system works with a
rolling code, after programming you must
synchronise the remote control integrated
in the rear-view mirror with the garage door
system receiver.

garage door opening system's operating
instructions, e.g. the sections on "Synchro-
nising the transmitter" or "Registering a new transmitter". You can also call the hot-
line mentioned above.

To obtain an accurate display of your com-
pass bearing, the correct geographical zone
must be set. If necessary, the compass must
also be calibrated (Y page 167).
If the compass is not calibrated or is malfunc-
tioning due to external interference, you will
see the Compass – – – message in the dis-
play.
i Large buildings, bridges, power lines or
large transmitting masts as well as metallic objects in or on the vehicle may interfere
with the compass display.
Setting the compass* X

installed in your vehicle.
In order to calibrate the compass correctly,
observe the following points:
R
find a suitable place where you can drive
the vehicle a full circle.
R calibrate the compass in the open and not
in the vicinity of steel constructions or high-
voltage transmission lines.
R switch off electric consumers, e.g.
Thermatic /multi-zone Thermotronic*,
windscreen wipers or rear window heating.
R close all doors and the tailgate. Features

compass calibration is impossible because of
external interference. Repeat calibration at
another location. Floormat* on the driver's side
G
Risk of accident
Make sure that there is sufficient clearance
around the pedals when floormats are used,
and that the floormats are properly secured.
The floormats must be correctly secured at all
times using retainers and press-studs. Before you drive off, check the floormats and
secure if necessary. A floormat which is not
properly secured can slip and, thereby, inter-
fere with the movement of the pedals.
Do not place floormats on top of one another.

The infrared reflecting glass prevents the
vehicle interior from becoming too hot. It also
blocks radio waves up into the gigahertz

! Refuel using only unleaded, sulphur-free
premium grade petrol with a minimum
octane number of 95 RON/85 MON con-
forming to European standard EN 228.
Otherwise, you could impair engine output
or damage the engine. i
As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the quality of the avail-
able fuel may not be adequate and could
cause coking around the inlet valve. In such
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
Further information on "Fuel" (Y page 287). Diesel (EN 590, DIN 51628)
G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628. Otherwise, you could
impair engine output or damage the engine.
! When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used.
! In countries in which diesel with a higher
sulphur content is available, the engine oil
should be renewed at more frequent inter-
vals. More information about intervals for
changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with the
EN 590 European standard or the Refuelling

Depending on driving style, the vehicle con-
sumes up to 0.8 l oil per 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.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Using the on-board computer*
i Only possible on the GL 450 CDI 4MATIC.
On all other models, a dipstick is used to
check the engine oil level (Y page 177).
X Make sure that the key is in position
2(Y page 63) in the ignition lock.
X Press the &or* button to select the
following message: The measurement takes a few seconds. You
will see one of the following messages in the
multi-function display:
R

ture and there is too much oil, you will see the
following message:

X Have excess oil siphoned off.
! There is a risk of damage to the engine or
the catalytic converter if there is excess oil
in the engine.

X Repeat the measurement after about five
minutes if the engine is at normal operating
temperature.
X Repeat the measurement after about
30 minutes if the engine is not at normal
operating temperature (if the engine was
only started briefly).
The following message appears if the engine
is running:
Engine oil level Not when engine on
X Switch off the engine and wait for five
