MERCEDES-BENZ CLS COUPE 2010 Owners Manual

close to crash barriers or similar solid lane
borders.
Two Active Blind Spot Assist sensors are inte-
grated into the front and rear bumpers
respectively. An additiona lsensor is located
behind the cover in the radiator grille. Make
sure that the bumpers are free from dirt, ice
or slush around the sensors. The rear radar
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 radar
sensors checked at a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. Active Blind Spot Assist may other-
wise fail to work correctly.
Indicator and warning display :
Yellow indicator lamp/red warning lamp
When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights
up in yellow at speeds of up to 30 km/h. At
speeds above 30 km/h, the indicator lamp
goes out and Active Blind Spot Assist is
operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding 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 12 km/h. The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
then no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Active Blind Spot Assist is not active at speeds
below 30 km/h. The indicator lamps in the
exterior mirrors are yellow. Vehicles in the
monitoring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Optical and acoustic collision warning
When you switch on the appropriate turn sig-
nals to change lanes, and a vehicle is detec-
ted in the side monitoring range of Active
Blind Spot Assist, you receive an optical and
acoustic collision warning. You then hear a
double warning tone, and red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :.There are no fur-
ther warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of
lateral collision in the monitoring range,
under certain circumstances, it will brake the
vehicle briefly on one side. This is designed to
help you avoid a collision.
This function is available in the range between
30 km/h and 200 km/h.
When a course-correcting brake application
occurs, red warning lamp :flashes in the
exterior mirror and the following is shown in
the multifunction display, for example: 188

G
Risk of accident
Active Blind Spot Assist is only an aid
designed to assist driving .Itis not a substitute
for attentive driving. Automatic braking by the
system may not always be sufficient to avoid
a collision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapty our driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles and/or obstacles, e.g.
crash barriers, in the immediate vicinity of
your vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you brake or accelerate decisively.
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake. R
ESP ®
is deactivated.
R a loss of tyre pressure or a defective tyre
has been detected and displayed.
Activating Active Blind Spot Assist
X Make sure that the radar sensor system
(Y page 210) and Active Blind Spot Assist
(Y page 204) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Warning lamps :light up red in the exte-
rior mirrors for approximately 1.5 seconds
and then turn yellow.
Active Lane Keeping Assist Important safety notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of a camera
at the top of the windscreen. Active Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
:
Active Lane Keeping Assist camera
If you select km on the on-board computer in
the Display unit Speed-/odometer: (Y
page 205) function, Active Lane Keeping
Assist is activated starting at a speed of
60 km/h. If the miles display unit is selected,
the assistance range begins at 40 mph. Driving systems

G
Risk of accident
Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid and
may detect the lane markings on the road
incorrectly or not at all.
The system may be impaired or may not func-
tion if:
R several or no lane markings for a single lane
are present.
R there is poo rvisibility, e.g. due to insuffi-
cien tillumination of the road, or due to
snow, rain, fog or spray.
R there is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
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 on the road are unclear,
e.g. near roadworks.
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
R the road is narrow and winding.
Active Lane Keeping Assist cannot detect
road and traffic conditions. It is not a substi-
tute for attentive driving. You are responsible
for the vehicle's speed, braking in good time,
and steering correctly. Always adapt your
driving style to suit the prevailing road and
weathe rconditions .Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
Warning vibration in the steering wheel
A warning can be given when 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. 5seconds. In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R
you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend.
No warning vibration occurs if:
R you clearly and actively steer, brake, or
accelerate.
R you cut the corner on a sharp bend.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
R you switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Lane-correcting brake application
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Befor ethis, a warning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
If a lane-correcting brake application occurs,
the following message appears in the multi-
function display: 190

A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. G
Ris
kofa ccident
Active Lane Keeping Assist does no tkeep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Corrective braking may
not always be sufficien tto return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correc tsteering and for braking in good time.
Always adap tyour driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake, or
accelerate.
R you cut the corner on a sharp bend. R
you switch on the turn signals.
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.
R you have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
R ESP ®
is deactivated.
R the transmission is not in position D.
R a loss of tyre pressure or a defective tyre
has been detected and displayed.
Active Lane Keeping Assist does not detect
road and traffic conditions. An inappropriate
brake application may be interrupted at any
time if you:
R steer slightly in the opposite direction
R use a turn signal
R clearly brake or accelerate
Al ane-correcting brake applicatio nis inter-
rupted automatically if:
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.
R lane markings can no longer be recognised.
