ing lamp comes on
while the engine is run-
ning.The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may
be blocked or the electric engine radiator fan may be malfunc-
tioning.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
XObserve the additional display messages in the multifunction
display.

notes (
Ypage 539).
XIf you have to add coolant frequently, have the engine cooling
system checked.
XMake sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
XDo not start the engine again until the coolant temperature is
below 248‡(120 †). Otherwise, the engine could be damaged.

The red coolant warn-
ing lamp comes on
while the engine is run-
ning. A warning tone
also sounds.The coolant temperature has exceeded 248 ‡ (120 †). The air-
flow to the engine radiator may be blocked or the coolant level may
be too low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.

The yellow combination
low tire pressure tell-
tale/TPMS malfunction
telltale for the TPMS
(pressure loss or mal-
function) is lit.The tire pressure monitor has detected a loss of pressure in at
least one of the tires.
GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed
increase.
Rthey may wear excessively and/or unevenly, which may greatly
impair tire traction.
Rthe driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 171).
XObserve the additional display messages in the multifunction
display.
XCheck the tires and, if necessary, follow the instructions for a
flat tire (

XCheck the tire pressure (Ypage 575).
XIf necessary, correct the tire pressure.

COMAND

Useful information
i
These operating instructions describe all
the standard and optional equipment of
your COMAND system, as available at the
time of going to print. Country-specific dif-
ferences are possible. Please note that
your COMAND system may not be equip-
ped with all the features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops: (
Ypage 34).
Operating safety
Important safety notes
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating COMAND.
COMAND calculates the route to the destina-
tion without taking account of the following,
for example:
Rtraffic lights
Rstop and yield signs
Rmerging lanes
Rparking or stopping in a no parking/no
stopping zone
Rother road and traffic rules and regulations
Rnarrow bridges
COMAND can give incorrect navigation com-
mands if the actual street/traffic situation
does not correspond with the digital map's
data. Digital maps do not cover all areas nor
all routes in an area. For example, a route may
have been diverted or the direction of a one-
way street may have changed.
For this reason, you must always observe
road and traffic rules and regulations during
your journey. Road and traffic rules and reg-
ulations always have priority over the sys-
tem's driving recommendations.
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of con-
sulting the map display for directions. Look-
ing at the icons or map display can distract
you from traffic conditions and driving, and
increase the risk of an accident.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h) your vehicle covers
a distance of 44 feet (approximately 14 m)
per second.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio fre-
284Operating safety
COMAND

quency (RF) Exposure Guidelines in Supple-
ment C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). But it is desirable that it should be
installed and operated with at least8inches
(20 cm) and more between the radiator and a
person's body (excluding extremities: hands,
wrists, feet and legs.)
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
iUSA only: The wireless devices of this
vehicle comply with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1) These devices may not cause interfer-
ence, and
2) These devices must accept any interfer-
ence, including interference that may
cause undesired operation of the device.
Changes or modifications not expressly
approved by the party responsible for com- pliance could void the user's authority to
operate the equipment.
iCanada only: The wireless devices of this
vehicle comply with Industry Canada
license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1) These devices may not cause interfer-
ence, and
2) These devices must accept any interfer-
ence, including interference that may
cause undesired operation of the device.
Correct use
Observe the following information when using
COMAND:
Rthe safety notes in this manual
Rtraffic rules and regulations
Rlaws and safety standards pertaining to
motor vehicles
iWork improperly carried out on electronic
components or systems (e.g. radio, DVD
changer) and associated software could
cause them to cease functioning. Even sys-
tems that have not been modified could be
affected because the electronic systems
are connected. Electronic malfunctions
can seriously jeopardize the operational
safety of your vehicle.
iRoof antenna functionality (telephone,
satellite radio, GPS) can be affected by the
use of roof carrier systems.
Attaching metalized retrofit film to the
windshield may affect radio reception and
have a negative impact on all other anten-
nas (e.g. emergency antenna) in the vehicle
interior.
iTherefore, have all work on or modifica-
tions to electronic components carried out at a qualified specialist workshop. This
workshop should have the necessary spe-
cialist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use an authorized
Mercedes-Benz Center for this purpose. In
particular, work relevant to sa
fety or on
safety-related systems must be carried out
at a qualified specialist workshop.
iProtection against theft: this device is
equipped with technical provisions to pro-
tect it against theft. Further information on
protection against theft can be obtained
from an authorized Mercedes-Benz Center.
