The trunk is the preferred place to carry
objects.
Warning!G
In order to help prevent spilling liquids
on vehicle occupants and/or vehicle
equipment, only use containers that fit into
the cup holder. Use lids on open containers
and do not fill containers to a height where
the contents, especially hot liquids, could
spill during braking, vehicle maneuvers, or in
an accident. Liquids spilled on vehicle
occupants may cause serious personal
injury. Liquids spilled on vehicle equipment
may cause damage not covered by the
Mercedes-Benz Limited Warranty.
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
Keep in mind that objects placed in the cup
holder may come loose during hard braking,
vehicle maneuvers, or in an accident and be
thrown around in the vehicle interior. Ob-
jects thrown around in the vehicle interior
may cause an accident and/or serious per-
sonal injury.

Cigarette lighter
Switch on the ignition (page 37).1Cigarette lighter
Push in cigarette lighter1.
Cigarette lighter1 will pop out auto-
matically when hot.
Reinsert cigarette lighter1 in its
socket after use.
Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do not injure themselves or start a fire
with the hot cigarette lighter.
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
!The lighter socket can be used to
accommodate 12V DC electrical accessories
(up to a maximum of 85 W) designed for use with
the standard “cigarette lighter” plug type. Keep
in mind, however, that connecting accessories
to the lighter socket (for example extensive con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, the lighter may no
longer be able to be placed in the heating
(pushed-in) position, or the lighter may pop out
too early with the lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC
electrical accessories designed for use with the
standard “cigarette lighter” plug type to the 12V
power outlets (
page 257) in your vehicle
whenever possible.

Warning!G
Whenever you are using floormats, make
sure there is enough clearance and the
floormats are securely fastened.
Floormats should always be securely fas-
tened using eyelets4 and retainer pins5.
Before driving off, check that the floormats
are securely in place and adjust them if
necessary. 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.
iTo install or remove the floormat more
easily, move the driver’s seat as far to the rear

Telephone*
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.
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.
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, pos-
sibly resulting in an accident and/or serious
personal injury.
Warning!G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. 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 telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the audio system or
COMAND*
1 if road, weather and traffic con-
ditions permit.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
