G
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
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.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing, for example:

Traffic lights


Stop and right-of-way signs


Parking or stopping prohibited areas


Lane merging


Other road and traffic rules and regula-
tions


Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual
road/traffic situation. DVD maps do not
cover all areas nor all routes within an area.
For example, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.
Warning!
G
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
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.

233 Control systems
COMAND navigation system (route guidance)
COMAND navigation system (route guidance)
Route guidance
COMAND guides you to the destination us-
ing navigation commands in the form of
audible navigation announcements and
route guidance displays.
If, for any reason, you do not follow the
navigation commands or if you leave the
calculated route, COMAND automatically
calculates a new route to the destination.
If the map data contains the relevant infor-
mation, COMAND tries to avoid roads that
only have limited access, e.g. roads closed
to through-traffic and non-residents.Roads that have time restrictions (e.g.
closed on Sundays and public holidays) are
not considered for route guidance, if the
digital map contains the relevant informa-
tion.
Examples of displays and announce-
ments for a driving maneuver
Driving maneuvers have three phases:

Preparation phase


Announcement phase


Maneuver phase

You have reached your destination.


“Area of dest. reached”
You have arrived in the area of your
destination. The message appears, for
example, for relatively large POIs.


“New Route…”
COMAND calculates a new route, e.g.
because you have deviated from the
calculated route or due to a detour re-
port. Afterward, COMAND continues
route guidance.

The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window sun-
shade is in raised position.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.

G
DISTRONIC Plus adaptive cruise control is
no substitute for active driving involvement.
It does not react to pedestrians or stationary
objects, nor does it recognize or predict the
curvature and lane layout or the movement
of vehicles ahead. DISTRONIC Plus can only
apply a maximum of 40% of the vehicle’s
braking power.
DISTRONIC Plus may not detect narrow ve-
hicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle.
High-frequency sources such as toll sta-
tions, speed measuring systems etc. can
cause the DISTRONIC Plus system to tem-
porarily cease functioning.
Warning!
G
DISTRONIC Plus requires familiarity with its
operational characteristics. We strongly rec-
ommend that you review the following infor-
mation carefully before operating the
system.Warning!
G
DISTRONIC Plus cannot take street and traf-
fic conditions into account. Only use
DISTRONIC Plus if the road, weather and
traffic conditions make it advisable to travel
at a steady speed.Warning!
G
Use of DISTRONIC Plus can be dangerous
on slippery roads. Rapid changes in tire trac-
tion can result in wheel spin and loss of con-
trol.
DISTRONIC Plus does not act upon adverse
sight distance conditions. Do not use
DISTRONIC Plus during conditions of fog
and heavy rain, snow or sleet.Warning!
G
DISTRONIC Plus cannot take weather condi-
tions into account. Switch off
DISTRONIC Plus or do not turn it on if:

roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.


the sensor is dirty or visibility is
diminished due to snow, rain or fog. The
distance control could be impaired.
Always pay attention to traffic conditions
even while DISTRONIC Plus is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.

Warning!
G
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not DISTRONIC Plus is activated.
Use of DISTRONIC Plus can be dangerous
on winding roads as conditions do not allow
safe driving at a steady speed.
DISTRONIC Plus may not react to stationary
objects in the roadway (e.g. a stopped vehi-
cle in a traffic jam or a disabled vehicle).
DISTRONIC Plus will also not respond to on-
coming vehicles.
Switch off DISTRONIC Plus:

when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane


when entering a turn lane or highway off
ramp


in complex driving situations, such as in
highway construction zones
In these situations, DISTRONIC Plus will
continue to maintain the set speed unless
deactivated.
DISTRONIC Plus is designed and intended
only to maintain a set speed and keep a set
distance from moving objects in front of it.
i
Do not use DISTRONIC Plus if you are driv-
ing on a road with steep uphill or downhill slopes.
i
Due to its radar-emitting nature DISTRONIC
Plus may have an appearance similar to a radar
detector to law enforcement officials. You may
want to refer to this section of your Operator’s
Manual when asked.
