Changing lanes
If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if:
Ryou are driving at a speed greater than
45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RDistance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
iWhen you change lanes, Distance Pilot
DISTRONIC monitors the left lane.
Stopping
GWARNING
If you leave the vehicle when it is only being
braked by Distance Pilot DISTRONIC, it could
roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDistance Pilot DISTRONIC is switched off
using the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always deactivate
Distance Pilot DISTRONIC and secure the
vehicle against rolling away.
Further information on deactivating Distance
Pilot DISTRONIC (
Ypage 136).
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
The elect
ric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
Rthe driver's seat belt is not fastened and the
driver's door is open
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
Ra system malfunction occurs
Rthe power supply is insufficient
If a malfunction occurs, the transmission may
also shift to position jautomatically.
Setting a speed

This will only happen if ATTENTION ASSIST still
detects typical indicators of fatigue or increas-
ing lapses in concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 150) and Lane Keeping
Assist (Ypage 152).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you will
also receive an optical and audible warning.
Blind Spot Assist supports you from a speed of
approximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe 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.
iUSA only:
This device has been approved by the FCC as
a "Vehicular Radar System". The radar sensor is intended for use 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 tam-
per 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.
Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, e.g. by overhang-ing loads. Following a severe impact or in the
event of damage to the bumpers, have the func-
tion of the radar sensors checked at a qualified
specialist workshop. Blind Spot Assist may no
longer work properly.
Monitoring area
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow 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 other road boundaries
Vehicles in the monitoring range are then not
indicated.
150Driving systems
Driving and parking
(Example)
At a distance of around 1.6 ft (0.5 m);from the
vehicle, Blind Spot Assist monitors the area up
to 10 ft (3 m) next to =and behind :your
vehicle, as shown in the picture.
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 driv-
ing 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
Rwarnings may be interrupted when driving
alongside long vehicles, e.g. trucks, for a pro-
longed time
Warning lamp
:Warning lamp Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If Blind Spot Assist is activated, warning lamp
:
in the exterior mirrors lights up yellow at speeds
of up to 20 mph (30 km/ h). At speeds above
20 mph (30 km/h), the warning lamp goes out
and Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Blind Spot Assist
is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. The red warning lamp flashes on the
relevant exterior mirror. If the turn signal
remains on, detected vehicles are indicated by
the flashing of the red warning lamp on the exte-
rior mirror. There are no further warning tones.
Activating Blind Spot Assist
XMake sure that Blind Spot Assist is activated
in the on-board computer (Ypage 163).
XSelect SmartKey position 2with the Start/
Stop button.
Warning lamps in the exterior mirrors light up
red for approximately 1.5 seconds and then
turn yellow.

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era:which is attached behind the top of the
windshield. Lane Keeping Assist detects lane
markings on the road and can warn you before
you leave your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/hand 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist. If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep-
ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no or several unclear lane markings
for one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
Switching on Lane Keeping Assist
XActivate Lane Keeping Assist using the on-
board computer; to do so, select Standardor
Adaptive(Ypage 164).
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected,

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper- age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and value. The fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is on the fuse box in the
cargo compartment (
Ypage 257).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. an authorized Mercedes-Benz Center.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
!Make sure that no moisture can enter the
fuse box when the cover is open.
!When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
