motion, you must only do so if the traffic sit-
uation permits. Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and yours afety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterio raerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial.

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.

ured at a filling station with a pressure gauge.
The tyre pressures shown by the on-board
computer refer to those measured at sea
level. At high altitudes, the tyre pressure val-
ues indicated by a pressur
egauge are higher
than those shown by the on-board computer.
In this case, do no treduce the tyre pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Checking tyre pressure electronically X
Make sure that the key is in position 2
(Y page 143)in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The curren ttyre pressur efor each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for over
20 minutes, the message Tyre pressureswill be displayed after a few
minutes of driving appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyrepressure monitor active display mes-
sage is shown instead of the tyre pressure
display .The tyre pressures are already being
monitored.
i If a spare wheel is fitted, the system may
continue to show the tyre pressure of the
wheel that has been removed for a few
minutes. If this occurs, note that the value
displayed for the position where the spare
tyre is fitted is not the same as the spare
tyre's current tyre pressure. Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display.
Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
X If the Please correct tyre pres‐ surePlease correct tyre pressure
message appears in the multifunction dis-
play, check the tyre pressure on all four
wheels and correct it if necessary.
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Restarting the tyre pressure monitor When you restar
tthe tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new referencev alues after you
have changed the tyre pressure .However,
you can also define reference values man-
ually as described here.
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page 325).
X Make sure that the key is in position 2
(Y page 143) in the ignition lock.
