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.

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.

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-
