Tips for driving with DISTRONIC PLUS
General notes
Pay particular attention in the following traffic
situations:
RCornering, going into and coming out of a
bend
RVehicles traveling onadifferent line
ROther vehicles changinglanes
RNarrow vehicles
RObstructions and stationary vehicles
RCrossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles traveling onadifferent line
DISTRONIC PLUS may not detectvehicles
traveling onadifferent line. The distance to
the vehicle in frontwill be too short.
Driving systems185
Driving and parking
Z

Other vehicles changing lanes
DISTRONIC PLUS has not detected the
vehicle cutting in yet. The distancetothis
vehicle will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in frontonthe edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the detected vehicle turnsacorner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away,especiallyonsteep
slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.

ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognizefatigue
or increasing inattentiveness in time or fail to
recognizethem at all. The system is not a
substitute forawell-rested and attentive
driver.
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on 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 takeabreak.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
Ryour personal driving style, e.g. steering
characteristics
Rjourney details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the road condition is poor, e.g. if the
surface is uneven or if there are potholes
Rif there isastrongside wind
Rif you have adoptedasporty driving style
with high cornering speeds or high rates of
acceleration
Rif you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
Rif you are currently using COMAND or
makingatelephone call with it
Rif the time has been set incorrectly

Lane Tracking package
General notes
The Lane Tracking package consistsofBlind
Spot Assist (Ypage 207) and Lane Keeping
Assist (Ypage 209).
Blind Spot Assist
General notes
Blind Spot Assist usesaradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you fromaspeed of
approximately 20 mph(30km/h).Awarning
displayinthe exteriormirrors draws your
attention to vehicles detected in the
monitored area. If you thenswitchonthe
correspondingturnsignal to change lanes,
you will also receiveavisual and audible
collision warning. BlindSpot Assist uses
sensors in the rear bumper for monitoring
purposes.
For BlindSpot Assist to assist you, the radar
sensor system must be operational.
Important safety notes
GWARNING
BlindSpot Assist does not reactto:
Rvehicles overtaken too closely on the side,
placingtheminthe blind spot area
Rvehicles which approach withalarge speed
differential and overtake your vehicle
Asaresult, Blind Spot Assist may not give
warnings in such situations. There isarisk of
an accident.
Always observe the traffic conditions
carefully, and maintainasafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

This device has been approved by the FCC
asa"Vehicular RadarSystem". The radar
sensor is intended foruse in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rpoor visibility, e.g. due to fog, heavy rain,
snow or spray
Rnarrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or similarlane borders
Vehiclesinthemonitoringrangeare then not
indicated.
BlindSpotAssist monitors the area up to
10 ft (3 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if there are vehicles driving at the
inner edge of their lanes.
Due to the nature of the system:
Rwarnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for
example by cycle racks or overhanging loads.
Followingasevere impact or in the event of
damage to the bumpers, have the function of
the sensors checked ataqualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display
