Control and operation of radio 
transmitters
COMAND system, radio and telephone*
Telephones and two-way radios
Radio transmitters, such as a portable 
telephone or a citizens band unit should 
only be used inside the vehicle if they are 
connected to an antenna that is installed 
on the outside of the vehicle.
Refer to the radio transmitter operation 
instructions regarding use of an external 
antenna.
Catalytic converter (gasoline engine)
Your vehicle is equipped with monolith-
ic-type catalytic converters, an important 
element in conjunction with the oxygen 
sensors to achieve substantial control of 
the pollutants in the exhaust emissions. 
Keep your vehicle in proper operating con-
dition by following our recommended 
maintenance instructions as outlined in 
your Maintenance Booklet.
Warning!
G
Do not forget that your primary respon-
sibility is to drive the vehicle. Only operate 
the COMAND system, radio or telephone
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 
44 feet (approximately 14 m) every second.

Observe all legal requirements.
Warning!
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, 
possibly resulting in an accident and/or 
personal injury.
!
To prevent damage to the catalytic convert-
ers, use only premium unleaded gasoline in this 
vehicle.
Any noticeable irregularities in engine operation 
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat and potentially 
start a fire.
