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 rec-
ommend that you pull over to a safe location 
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the 
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from 
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km / h), your vehicle is 
covering a distance of 44 feet (approximate-
ly 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, pos-
sibly resulting in an accident and/or 
personal injury.

the outside of the vehicle.
The external antenna must be approved by 
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved 
external antenna. Refer to the radio trans-
mitter operation instructions regarding use 
of an external antenna.
Before driving off, check that the floormats 
are securely in place and adjust them if nec-
essary. A loose floormat could slip and 
hinder proper functioning of the pedals.
Do not place several floormats on top of 
each other as this may impair pedal move-
ment.

Catalytic converter (gasoline engine)
Your vehicle 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 Maintenance Booklet.

To prevent damage to the catalytic convert-
ers, only use 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, which could 
potentially start a fire.
