Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 188) and Lane Keeping
Assist (Ypage 190).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph(30 km/h). A warning
display in the exteriormirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turnsignal to change lanes,
you will also receive a visual and audible
collision warning. For this purpose, Blind Spot
Assist uses sensors in the rear bumper.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing theminthe 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
carefully, 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.
iUSA only:
This device has been approved by the FCC
as a "VehicularRadar 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 notpermitted by the
188Driving systems
Driving and parking

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
Rthere is poor visibility, e.g. due to fog, heavy
rain or snow
Ra narrow vehicle traveling in front, e.g. a
motorbike or bicycle
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 similar lane borders
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to
10 ft(3.0m)behind your vehicle and directly
nextto your vehicle, as shown in the diagram.
For this purpose, Blind Spot Assist uses radar
sensors in the rear bumper.
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 the vehicles are driving on the
inner side of their lane.
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 particularly long vehicles, e.g.
trucks, for a prolonged time.
The two 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 vicinityofthe sensors. For
example, the radar sensors must not be
covered by bicycle racks or overhanging
loads. Following a severe impact or in the
event of damage to the bumpers, have the
function of the radar sensors checked at a
qualified specialist workshop. Blind Spot
Assist may otherwise not work properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lampin the exterior mirrors lights up
yellow at speeds of up to 20 mph(30km/h).
At speeds above 20 mph (30 km/h), the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected withinthe monitoring
range of Blind Spot Assist at speeds above
Driving systems189
Driving and parking
Z

20 mph (30km/h), then warning lampon
the corresponding side lights up red. This
warning is always emitted whenavehicle
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 than7mph
(12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lampflashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp.There are no further warning tones.
Switching on Blind Spot Assist
XMake sure that Blind Spot Assist is
activated in the on-board computer
(Ypage 205).
XTurn the SmartKey to position2in the
ignition lock.
Warning lampsin 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 a camera at
the top of the windshield. Lane Keeping Assist
detects lane markings on the road and warns
you before you leave your lane
unintentionally.
Lane Keeping Assist camera
If you selectkmon the on-board computer in
theDisplay Unit Speed-/Odometer
function (Ypage 206), Lane Keeping Assist
is active starting ataspeed of 60 km/h. If the
milesdisplay unit is selected, the assistance
range begins at 40 mph.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
returnthe 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
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in

front, for vehicle speed, for braking in good
time and for staying in yourlane.
The Lane Keeping Assist does notkeep the
vehicle 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 spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
Rthere are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
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 lane
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.

WhenStandardis selected, no warning
vibration occurs if:
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Ra driving safety system intervenes, such as
ABS, BAS or ESP®.

Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a
freeway.
Rthe system recognizes solid lane markings.
