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.When the mobile phone is inserted in the
cradle, you can operate the telephone us-
ing the following devices:
mobile phone keypad
COMAND telephone keypad
(page 115)
buttonss andt on the steering
wheel (

See also separate operating manual for in-
structions on how to use the mobile phone.
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 COMAND (Cockpit Man-
agement and Data System)
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 (approximate-
ly 14 m) every second.
1Observe all legal requirements.

tion steering wheel.
The battery is charged depending on its
charge status and the position of the
SmartKey in the starter switch. The
charge procedure will be indicated in
the mobile phone’s display.
You can place or receive phone calls. You
can control other functions of the mobile
phone via the control system (

Tires
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.6 mm), at which point
the tire is considered worn and should be
replaced.The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subject to extreme operating con-
ditions (e.g. high speeds, heavy loads, high
ambient temperatures).
Turn the SmartKey to starter switch po-
sition 0 and remove the SmartKey from
the starter switch, or press the
KEYLESS-GO* start/stop button
(page 317).
Take the SmartKey or the SmartKey with
KEYLESS-GO
* with you and lock the
vehicle when leaving.
!
Set the parking brake whenever parking or
leaving the vehicle. In addition, shift the auto-
matic transmission to P.
When parking on hills, always turn front wheels
towards the road curb.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tio n to an a rea whic h is a s afe d ista nc e fro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest Mercedes-Benz Center or tire
dealer for repairs.
Warning!
G
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the treadwear indicators (TWI) be-
come visible at approximately
1/16 in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1/8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Never allow sparks, flame or smoking
materials near gasoline!

skin or clothing. Direct skin contact with fu-
els and the inhalation of fuel vapors are
damaging to your health.
Switch off the engine before refueling.
