!Vehicles with rain sensor*:
Do not leave in intermittent setting
when vehicle is taken to an automatic
car wash or during windshield cleaning.

water sprayed on the windshield, and
wipers may be damaged as a result.

mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass when wiping occurs on a dry
windshield.

shield wipers, switch off the wipers.

79 Safety and Security
Anti-theft systems
Anti-theft systems
Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
Activating
Removing the key from the starter
switch activates the immobilizer.
Deactivating

Inserting the key in the starter switch
deactivates the immobilizer.
Anti-theft alarm system*
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
a door

the tailgate

the hood.
The alarm system will also be triggered
when

someone attempts to raise the vehicle

the vehicle is opened with the mechan-
ical key.Arming the alarm system
The alarm system is armed after locking
the vehicle with the remote control. The
turn signal lamps blink three times to indi-
cate that the alarm system is activated.
A red lamp in the switch for the tow-away
alarm will blink after approximately
10 seconds when the alarm system is
completely armed.
iIn case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Center
or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).
iIf the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid* sys-
tem (
page 211) provided Tele Aid*
service was subscribed to and properly
activated, and that necessary cellular
service and GPS coverage are avail-
able.
iIf the turn signal lamps do not blink
three times, the tow-away sensor* is
malfunctioning or one of the following
elements may not be properly closed:
a door

the tailgate

the hood
Close the respective element and lock
the vehicle again.

106 Controls in detailInstrument clusterOutside temperature indicatorThe temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

141 Controls in detail
Good visibility
Good visibility
Information on the windshield wipers
(page 48) and for setting the rear view
mirrors (
page 39) is found in the “Get-
ting started” section.
Rear view mirror
Inside rear view mirror, antiglare posi-
tion
Tilt the mirror to the antiglare night po-
sition using the lever at its lower edge.
Automatic antiglare rear view mirror*
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the inside rear view mirror will respond au-
tomatically to glare when

the ignition is switched on, and

incoming light from headlamps falls on
the sensor in the inside rear view mir-
ror.
The rear view mirror will not react if

reverse gear is engaged

the interior lighting is turned on
Warning!
G
The automatic antiglare function does not
react if incoming light is not aimed directly
at sensors in the inside rear view mirror.
The inside rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Glare can endanger you and others.Warning!
G
In the case of an accident liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.

230 OperationDriving instructionsControl and operation of radio trans-mitter
COMAND*, radio and telephone*Telephones* and two-way radios
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.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
Catalytic converter
Your Mercedes-Benz 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 Service Booklet.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit Man-
agement and Data System), radio or tele-
phone
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 approximately
44 feet (approximately 13.5 m) every sec-
ond.
1Observe 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, pos-
sibly resulting in an accident and/or
personal injury.
!To prevent damage to the catalytic con-
verters, use only premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and start a fire.

271 Practical hints
What to do if …
When the
ENGINE OIL LEVEL – CHECK LEV-
EL!
message appears while the engine is
running and at operating temperature, the
engine oil level has dropped to approxi-
mately the minimum mark on the dipstick.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the “full”
mark on the dipstick with an approved oil.
!The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in se-
rious engine damage that is not cov-
ered by the Mercedes-Benz Limited
Warranty.
