Important safety notes G
WARNING
Always remember that you must concentrate
primarily on driving the vehicle. The driver's
concentration must always be directed
primarily at road traffic. For your own safety
and that of others, we recommend that you
stop the vehicle at a safe place and in
accordance
with the traffic conditions before
making or accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate the audio system or COMAND
(Cockpit Management and Data System) in
compliance with all legal requirements and
when the road, weather and traffic conditions
permit. You may otherwise not be able to
observe the traffic conditions, endangering
yourself and others.
Remember that your vehicle covers a distance
of 44 ft (approximately 14 m) a second when
it is traveling at only 30 mph (approximately
50 km/h). Drive sensibly – save fuel Observe the following tips to save fuel:
X
The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when
driving
in cold weather, in stop-and-go traffic
and in mountainous terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident
are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Pedals G
WARNING
Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or Driving tips

impacting the objects.
Even
if the object you approach is directly on
the ground, do not approach the object any
closer than the red guide line. Example: information in the COMAND display
Guide
lines ; and = show the approximate
distance to the rear area. Yellow guide
line ; indicates a distance of approximately
3 ft (1 m) and red guide line = indicates a
distance of approximately 10 in (0.25 m). The
distances only apply to objects that are at
ground level. Blue guide lines : depict the
width required for the vehicle. They are used
to align the vehicle with the edge of the road,
e.g. the curb. ATTENTION ASSIST
Important safety notes G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in
concentration too late or not at all. It is not a
substitute for a well-rested and attentive
driver.
Fatigue may cause you to recognize
hazardous situations too late, misjudge a
situation or react more slowly. For this
reason,
make sure you feel rested before you
begin driving and during your journey. Make
sure that you take regular breaks in time,
particularly on long journeys. Otherwise, you may fail to recognize dangers in time, cause
an accident and injure yourself and others.
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on freeways
and interstate highways. It is active in the
range between 50 mph (80 km/h
) and
112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R driving conditions, e.g. time, driving time
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the
surface is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R if you are currently using COMAND or
making a telephone call with it
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed Driving systems
