If you have problems when programming the
integrated remote control, please note the
following:
R check the transmitter frequency of garage
door remote control A(which can usually
be found on the back of the remote con-
trol).
The integrated remote control is compati-
ble with devices that have units which oper-
ate in the frequency range of 280 to
390 MHz.
R Replace the batteries in garage door
remote control A.This increases the prob-
ability of garage door remote control A
sending a strong and more precise signal
to the integrated remote control on the
rear-view mirror.
R when programming, hold garage door
remote control Aat varying distances and
angles from the transmitter button which
you are programming. Try various angles at
a distance between 5and 30 cm or at the
same angle but at varying distances.
R if there is another garage door remote con-
trol for the same device, perform the pro-
gramming steps again using that garage
door opener. Before performing these steps, make sure that new batteries have
been fitted in the garage door remote con-
trol.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

To avoid the risk of burns, only touch those
components described in the Owner's Manual
and observe the relevan tsafety notes. G
WARNING
The radiator fan between the radiator and the
engine can start automatically, even if the key
has been removed from th eignition lock. For
this reason, you must not reach into the fan
rotation area. You could otherwise be injured. Vehicles with
apetrol engine: The elec-
tronic ignitio nsystem uses high voltage. For
this reason, you mus tnever touch ignition
system components (ignition coil, ignition
cables, spark plug connectors or test socket)
while:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine

Checking the oil level using the oil dip-
stick
Example
:oil dipstick
On the G 65 AMG, the oil level can be checked
using the on-board computer only.
On all other models, the dipstick must be
used to chec kthe engine oil level.
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 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).
X Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
The oil level is correct if the level is between
MIN mark =and MAX mark ;.
X Top up the oil if necessary.
Checking the oil level using the on-
board computer !
Do not add too much oil. Topping up with
too much engine oil can result in damage
to the engine or to the catalytic converter.
Have excess engine oil siphoned off.

Do not touch the insides of the windows
with hard objects, e.g. an ice scraper or
ring. There is otherwise a risk of damaging
the windows.
! Cleant he water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away.T his
can lead to corrosion damage and damage
to electronic components.
X Cleant he inside and outside of the win-
dows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz. Cleaning the wiper blades G
WARNING
Switch off the windscreen wipers and remove
the key from the ignition lock before cleaning

screen wipers could otherwise move and
injure you.
! Do not pull on the wiper blade. Otherwise,
the wiper blade could be damaged.
! Do not clean wiper blades too often and
do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
! Hold the wiper arm securely when folding
back. The windscreen could be damaged if
the wiper arm hits against it suddenly.
X Fold the wiper arms away from the wind-
screen.
X Carefully clean the wiper blades with a
damp cloth.
X Fold the windscreen wipers back again
before switching on the ignition.
Cleaning the headlamps !

Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door.
X Place the warning triangle (Y page 304) or
warning lamps at a suitable distance.
Observe legal requirements. Battery (vehicle)
Important safety notes
Work on the battery, e.g. removing or instal-
ling, requires specialist knowledge and the
use of special tools. Therefore, always have
work on the battery carried out at a qualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to a short circuit and
damage your vehicle's electronic system. This
can disrupt driving safety systems such as
ABS (anti-lock braking system) or ESP ®
(Elec-
tronic Stability Program).
R If ABS malfunctions, the wheels can lock
during braking. This limits the steerability
of the vehicle when braking and the braking
distance may increase. There is a risk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it starts to skid or a wheel starts
to spin. There is a risk of accident.
You should therefore have all work involving
the battery carried out at a qualified specialist
workshop. Battery (vehicle)

For towing distances over 50 km, the entire
vehicle mus
tbe lifted up and transported.
! Only secure the tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Your vehicles is equipped with an auto-
matic transmission .Therefore, you must
not have the vehicle tow-started. The trans-
mission may otherwise be damaged. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could over-
turn.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per-
missible gross weight of your vehicle.
Information on your vehicle's gross vehicle
weight rating can be found on the vehicle
identification plate (Y page 340).
Observe the legal requirements for the rele-
vant countries when towing.
It is better to have the vehicle transported
than to have it towed.
If the transfer case can be shifted into neutral
N, you can tow the vehicle.
If the transfer case cannot be shifted into
neutral N, you can tow the vehicle with one
axle raised. Please bear the following in mind:
R remove the propeller shaft between the
transfer case and the rolling axle.
R turn the key to position 1in the ignition lock
(Y page 143). The battery must be connected and charged.
Otherwise, you:
R
cannot turn the key in the ignition lock to
position 2(Ypage 143)
R cannot shift the automatic transmission to
position N
i Deactivate the automatic locking feature

Electrical fuses
Important safety notes
G
WARNING
Only use fuses that have been approved for
Mercedes-Ben zvehicles and which have the
correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Using fuses which have not been
approved or attempting to repair or bridge
faulty fuses could cause the fuse to be over-
loaded and result in a fire. Have the cause traced and rectified at a qualified specialist
workshop.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle serve to disconnect
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replace dwith fuses of
the same rating, which you can recognise by
the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre. Before replacing a fuse
X Park the vehicle and apply the parking
brake.
X Switch off all electrical consumers.
X Remove the key from the ignition lock.
All indicator lamps in the instrumen tcluster
must be off.
The fuses are located in various fuse boxes:
R Main fuse box on the driver's side of the
dashboard
R Fuse box in the front-passenger footwell
R Fuse box in the transmission tunnel
R Fuse box in the battery case
