2013 MERCEDES-BENZ C-Class SEDAN Owner's Manual

Use Parking Guidance for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:
R On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 180) warning messages during the
parking procedure.
R When transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R Never use Parking Guidance with snow
chains or an emergency spare wheel
mounted.
R Make sure that the tire pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R The way you rvehicle is positioned in the
parking space after parkin gis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Parking
Guidance may guide you too far or not far
enough into a parking space. In some
cases, it may also lead you across or onto
the curb. If necessary, cancel the parking
procedure with Parking Guidance.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires. Detecting parking spaces 0002

Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol 0003as
a status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right 0022or the left 0002also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear.
Parking Guidance will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 5 ft (1.5 m) wide
R that are at least 4.3 ft (1.3 m) longer than
your vehicle
Ap arking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it. Driving systems

Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver. Driving systems
185Driving and parking Z

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 take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentratio nby taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey 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:
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 wit hit
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display X
Activate ATTENTION ASSIST using the on-
board computer (Y page 207).
Symbol 0002appears in the multifunction
display.
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the nhear an
intermittent warning tonet wice and the
Attention Assist: Drowsiness Detected message appears in the
multifunction display.
X If necessary, take a break.
X Press the 000Bbutton to confirm the
message.
On long journeys, take regular breaks in good
time to allow yourself to res tproperly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
precondition for this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue yourj ourney and starts assessing
your tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 186) and Lane Keeping
Assist (Y page 188).
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 speeds of
approximately 20 mph (30 km/h). A warning 186
Driving systemsDriving and parking

display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible
collision warning .Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
For Blind Spot Assist to assist you when
driving, the radar sensor system must be:
R activated(Y page 211)
R operational
Important safety notes
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
sufficien tdistance to the side for other road
users and obstacles. G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing the minthe blind spot area
R vehicles being overtaken at a speed
difference of more than 7.5 mph
(12 km/h)
R vehicles 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.
i USA only:
This device has been approved by the FCC
as a "VehicularR adar 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 no tpermitted 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:
R dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or
bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there 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 (3m) behind your vehicle and directly
nextt
o 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. Driving systems
187Driving and parking Z

Due to the nature of the system:
R
warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two rada rsensors 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.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the 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. 0002
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp 0002in the exterior mirrors lights up
yellow at speeds of up to 20 mph (30k m/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 withi nthe monitoring
range of Blind Spot Assist at speeds above
20 mph (30 km/h), warning lamp 0002on the
corresponding 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 7mph (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 lamp 0002flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp 0002.There are no further warning tones.

ignition lock.
Warning lamps 0002in the exterior mirrors
light up red for approximately
1.5 seconds and then turn yellow.
Lane Keeping Assist Important safety notes
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 your lane. G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings. 188
Driving systemsDriving and parking

In this case, Lane Keeping Assist may:
R
give an unnecessary warning
R not 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. G
WARNING
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
Keeping Assist.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient illuminatio nofthe road, or due
to snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are strong shadows cast on the lane General notes
Lane Keeping Assist monitors the area in
front of your vehicle with camera
0002, which is
mounted at the top of the windshield. Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. 0002

General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y
page 167),
Active Blind Spot Assist (Y page 190) and
Active Lane Keeping Assist (Y page 193).
Active Blind Spo tAssist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. Awarning
display in the exterior mirrors draws your
attentio nto vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If a risk of lateral collision is
detected, corrective braking may help you
avoid a collision. To support the course-
correcting brake application, Active Blind
Spot Assist uses the forward-facing radar
sensor system. The space available in the
direction of travel as well as to the side of the
vehicle is evaluated before a course-
correcting braking application is performed.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
R activated(Y page 211)
R operational
Important safety notes
Active Blind Spot Assist is only an aid. It does
not detect all traffic situations and road users
and is no substitute for attentive driving.
Always ensure that there is sufficient
distance to the side for other road users and
obstacles. 190
