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.

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.

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.

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.

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)
309Breakdown assistance Z

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
(Y page 74). You could otherwise be locked
