2012 MERCEDES-BENZ G-CLASS SUV warning

Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind yourv ehicle 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 the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, 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 vicinit yofthe sensors. The
radar sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam-
age to the bumpers, have the function of the
radar sensors checked at aqualified special-
ist workshop. Blind Spot Assist may other-
wise no twork properly. Indicator and warning display G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles approaching and driving by with a
speed difference of more than approx-
imately 11 km/h
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. :
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is switched on, indicator
lamp :in the exterior mirrors lights up yel-
low up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out
and 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
always occurs 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. Blind Spot Assist is then
deactivated. Driving systems

Important safety notes G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles approaching and driving by with a
speed difference of more than approx-
imately 11 km/h 192
Driving systemsDriving and parking

In such situations, Active Blind Spot Assist
cannot warn you or intervene. There is a risk
of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Active Blind Spot Assist is only an aid.Itm ay
fail to detect some vehicles and is no substi-
tute for attentive driving.
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors.
R visibility is poor, e.g .due to fog, heavy rain
or snow.
R there is a narrow vehicl etravelling in front,
e.g. a motorcycle or bicycle.
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 other road boundaries.
General notes Active Blind Spot Assist uses a rada
rsensor
system to monitor the side areas of your vehi-
cle which are behind the driver. Awarning
display in the exterior mirrors draws your
attentio nto vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lane, you will
also receive an optical and audible collision
warning. If a risk of lateral collision is detec-
ted, corrective braking may help you avoid a
collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facing radar sensor sys-
tem.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Monitoring range G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correct your course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
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.
Active Blind Spot Assist monitors the area up
to 3.0 m behind your vehicle and directly next
to your vehicle, as shown in the diagram. For
this purpose, Active 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 there are vehicles at the edge
of their lane nearest your vehicle. Driving systems

Due to the nature of the system:
R
warnings may be issued in error when driv-
ing close to crash barriers or simila rsolid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, for
example lorries, for a prolonged time.
Two Active Blind Spot Assist radar sensors
are integrated into the front and rear bumpers
respectively. An additional radar sensor is
located behind the cover in the radiator grille.
Make sure that the bumpers and the cover in
the radiator grille are free of dirt, ice or slush.
The rear sensors must not be covered, e.g. 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. Active Blind Spot Assist may oth-
erwise no longer work properly.
Indicator and warning display G
WARNING
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 and cause an acci-
dent and injure yourself and others. :
Yellow indicator lamp/red warning lamp
When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights up 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
always occurs 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.
Visual and acoustic collision warning When you switch on the turn signals to
change lanes and a vehicle is detected in the
side monitoring range, you receive a visual
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. 194

Course-correcting brake application
G
WARNING
Active Blind Spot Assist is only an aid
designed to assis tdriving. It is 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 adapt yourd riving style to suitthe
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. If a course-correcting brake application
occurs, red warning lamp
:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;appears in the
multifunction display.
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is designed to help you avoid a col-
lision.
The course-correcting brake application is
available in the range between 30 km/h and
200 km/h.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R a vehicle approaches too closely on 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, e.g.
ESP ®
.
R ESP ®
is deactivated.
R the LOW RANGE off-road gear is activated.
R a loss of tyre pressure has been detected.

audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe manoeuvring, parking and exiting a park-
ing space. Check in front, behind and to the
sides of the vehicle before manoeuvring,
parking or exiting a parking space. There
must not be any persons, animals or objects
in the area in which yo uare manoeuvring.
PARKTRONIC cannot identify any persons or
objects outside of the detection range. As a
result, PARKTRONIC cannot warn you about
objects in this area.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
