up and possibly a fire.
There is a risk of an accident.
X Stop the vehicle without making any sudden steering or braking
manoeuvres. Pay attention to the traffic conditions as you do
so.
X Secure the vehicle against rolling away (Y page 183).

X
Check the tyre pressures at the next opportunity
(Y page 386).
X If necessary, correct the tyre pressure.
X Restart the tyre pressure monitor (Y page 387).Wheel sensor(s)

Important safety notes G
WARNING
Observe the legal requirements of the country
in which you are currently driving regarding
operating mobile communications equipment
in a vehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you must only do so if the traffic sit-
uatio npermits .Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fa xequipment 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 your safety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterior aerial. 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.
i There are various mobile phone brackets
that may be fitted in your vehicle; in some
cases, these are country-specific.
i You can connect a Bluetooth ®
-capable
mobile phone with Audio 20, Audio 50 or
COMAND Online via the Bluetooth ®
inter-
face. This also applies if your vehicle is
equipped with convenience telephony.
More information on suitable mobile phones,
mobile phone brackets and on connecting
Bluetooth ®
-capable mobile phones with
Audio 20, Audio 50 or COMAND Online can
be obtained:
R at your Mercedes-Benz Service Centre
R on the Internet at http://www.mercedes-

i The functions and services available when
you use the phone depend on your mobile
phone model and service provider.

phone bracket, you can speak to the person
you are calling using the hands-free system.
