Downloaded from www.Manualslib.com manuals search engine Possible radar sensor function impairments
The adaptive cruise control will switch off tempora­
rily if th e radar sensor function is impaired , e .g .
due to heavy rain, spray , snow, ice or mud . A cor­
responding message will appear in the instrument
clu ster display .
Clean the radar sensors as re­
quired .
The adaptive cruise control will automatically be
available again as soon as the radar sensors are
no longer impaired . The message in the instrument
cluster display goes out, and the adaptive cruise
control can be reactivated .
~trong. reflected radiation of the radar signal , e.g.
1n mult1-storey car parks , can impair the function of
the radar sensor .
Towing a trailer
The adaptive cruise control operates with reduced
dynamics when the
vehicle is towing a trailer .
Overheated brakes
If the brak~s. overheat , e .g . following heavy braking
or when
dnv1ng down steep inclines for long peri­
ods , the
ada~tive cruise control may be deactiva­
ted
t~mpor~nly. A correspond ing message will ap­
p e ar
.m the tns~rument cluster display. lt is then not
poss1ble to act1vate the adaptive cruise control.
As soon as the temperature of the brakes has de­
creased sufficiently , the adaptive cruise control can
be activated again. The message in the instrument
cluster
display goes out. If the message ACC not
ava i 1 ab 1 e does not go out for a long time, there
is a fault. Proceed to a qualified workshop. Volks­
wagen recommends using a Volkswagen dealer­
ship for this purpose.

If the message ACC ready for start ap·
pears
in the instrument cluster display and
th_e vehicle in front moves off, your vehicle
w1ll move off automatically. In some cases
the radar
sensor may be unable to detect ob·
st~cles that are located in the vehicle's path.
Th1s can result in serious injury and acci·
dents.
l
• Always check the road ahead before the
veh~cle pulls away. If necessary, cancel the
pulling away procedure by depressing the
brake
pedal.

The area monitoring system (Front Assist) helps to
avoid rear-end collisions.
lt uses a radar sensor to monitor traffic situations
up to a distance of approximately 120 metres in
front of the vehicle within a speed range of approx­
i
mately 5 km/h (3 mph) to 210 km/h (130 mph) .
The area monitoring system (Front Assist) can
warn the driver about imminent collisions, pre­
pare the vehicle for emergency braking in case
of danger, assist with braking, and initiate auto­
matic braking.

Distance warning
If the system detects danger from driving too close
to.the vehicle in front , the system can warn the
~nver by showing a corresponding message in the
~nstrument cluster display ~page 236. The warn­
Ing Period varies according to the traffic situation
a
nd the driver's response . Front Assist is not a
sub t · · s ltue for the full concentration of the dnver .
Advance warning
h lfth e system detects a potential collision with a ve­ICI · e .e .1n front, the system can warn the driver by 1111tt1ng an acoustic warning and showing a corre-spond· · PI lng message in the instrument clus~er diS-
ay ~Page 236 . The warning period vanes ac- carding
to the
traffic situation and the driver's re­
sponse . Front Assist is not a substitue for the
full
concentration of the driver .
At the
same time it prepares the vehicle for possi­
ble emergency braking ~ ~.
Urgent warning
If the driver fails to respond to the advance warn­
ing, the system can initiate a quick jolt of the brake
in order to draw the driver's attention to the
in­
creasing danger of a collision.
Automatic braking
If the driver also fails to react to the urgent warn­
ing, the system can slow the vehicle down auto­
matically by gradually increasing the braking force.
The system can help to reduce the consequences
of an accident by reducing the speed at which a
potential collision might take place .
Brake assistance
If Front Assist detects that the driver is not braking
sufficiently when there is a risk
of collision , the sys­
tem can increase the braking force and thereby
help to prevent a collision . Brake assistance works
only
for as long as the brake pedal is pressed
hard.
The intelligent technology used in Front As­
sist cannot overcome the laws of physics.
The driver is always responsible for braking
in time. If Front Assist issues a warning, im­
mediately apply the foot brake to slow the ve­
hicle down or avoid the obstacle, depending
on the traffic situation.
• Adapt your speed and distance from the
vehicles ahead to suit visibility, weather, road
and traffic conditions.
• Front Assist cannot prevent accidents and
serious injuries on its own.
• Front Assist can issue unnecessary warn­
ings and carry out unwanted braking inter­
ventions in certain complex driving situa­
tions, e.g . at traffic islands.

The area in fron t of and around the radar sensor
must not be covered by objects such as stickers or
auxiliary headlights, as this can impair the function
of Front Assist.
Any structural modifications to the vehicle, e .g .
l
owering the vehicle or making alterations to the
front end tri m , can impair the function of Front As­
sist. Structural mod1fictions should therefore only
be carried out by a qualifie d workshop. Volkswa­
gen recommends using a Volkswagen dealership
for th is purpose.
Incorrectly performed repa irs to the fron t end of the
vehic le can alter the position of the radar sensor
and therefore tmpai r the functi on of Front Assist.
Repair work should therefore only be carrie d out
y a qualified workshop. Volkswagen recommends
u sm g a Volkswagen dealership for this purpose.
CD
Switch off Front Assist if you suspect that the
radar sensor has been damaged or its positio n
has been altered. This can help to prevent fur­
ther damage. Have the radar sensor realigned.
• The radar sensor could be moved if it is hit
for example in parking manoeuvres. Readjust-'
ing the sensor could impair the performance of
t h e system or cause it to be switched off.
• Repair work on the radar sensor w ill require
special knowledge and tools. Volkswagen rec­
ommends using a Volkswagen dealership for
this purpose.
• Remove snow with a brush, and remove ice
preferably with a solvent-free de-leer spray. ~rating the area monitoring system (Front Assist)
