Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
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.
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.

tional or has not been removed/replaced

may be impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
!Make sure no objects fall into the open-
ings of the subwoofer between the rear
seats.
If necessary, contact an authorized
Mercedes-Benz Center to remove any
objects which may have fallen into the
openings.
