Operation

Driving instructions

Radio transmitters, such as a portable tele-
phone or a citizens band unit should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.

Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.

Your Mercedes-Benz is equipped with 
monolithic type catalytic converters, an 
important element in conjunction with the 
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper 
operating condition by following our rec-
ommended maintenance instructions as 
outlined in your Service Booklet.

G

Please do not forget that your primary re-
sponsibility is to drive the vehicle safely. 
Only operate the COMAND (Cockpit Man-
agement and Data System), radio or tele-
phone

1

 if road, weather and traffic 

conditions permit.

Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is 
covering a distance of approximately 
44 feet (approximately 13.5 m) every sec-
ond.

Observe all legal requirements.

G

Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or 
personal injury.

!

To prevent damage to the catalytic con-
verters, use only premium unleaded 
gasoline in this vehicle.

Any noticeable irregularities in engine 
operation should be dealt with prompt-
ly. Otherwise, excessive unburned fuel 
may reach the catalytic converter, 
causing it to overheat and start a fire.
