T
e Park Ass ist system has certa in system-rela ted
limitations and th e driver should be particularly
carefully when using the Park Assist system => 4::,..
One element of the Park Assi st system is the Park­
Pilo~ which is des igned to provide assist an ce
when parkin g.
In vehicles w ith ParkP ilot optical display the scan ­
ned area to the front , rear and to the sides of the
vehicle will be shown on the screen of the radio or
the navigat ion sys tem. W ith in the scope permitted
by the sys tem , the pos it ion of obstacles w ill be

T he
Park Ass is t system cannot be sw itched on if
the factory -fitted towing bracket is e lectrically co n­

..._A W ARN ING
D o not le t the extra convenience afforded by
the Park Assist system tempt you into taking
any risks when driving-this can cause acci­
dents. The system is not a substitute for the
full concentration of the driver.
• Un intentional vehicle movements can
cause serious injury.
A WARNING (Continuec;f) -
• Always adapt your speed and driving style
to suit visibility, weather, road and traffic con­
ditions.
• The surface of certain objects, including
clothing, as well as external noise sources do
not reflect the signals from the Park Assist
system or the parking distance warning sen­
sors or can cause the system to fail to detect
objects or persons.
• Sensors have blind spots in which obsta­
cles and people cannot be detected.
• Always monitor the area around the vehi­
cle as the sensors will not always detect in­
fants, animals and objects.
..
A WARNING .. p k
When driving into or out of a parking space
using the Park Assist system, the steering
wheel will automatically make quick turning
movements. You could be injured if you at­
tempt to touch the steering wheel spokes.
• The Park Assist system uses parked vehi­
cles, the kerb and other objects as guidance.
Please ensure that the wheels and tyres are not
damaged when parking the vehicle. If necessa­
ry, stop the parking procedure in good time to
prevent damage to the vehicle.
• The sensors may not always be able to de­
tect objects such as trailer drawbars, thin rails,
fences, posts, trees and open or opening tail ­
gates. This can result in damage to your vehi­
cle.
•
If the ParkPilot has detected an obstacle
and issued a warning, the obstacle may move
out of the detection range of the sensors as the
vehicle approaches it, particularly if the object
is very high or very low. These objects are no
longer registered. The vehicle can sustain con­
siderable damage if the warning given by the
ParkPilot is ignored. The same applies to the
Park Assist system, for example when parking
behind a lorry o r a motorbike. Therefore, al­
ways check the space in front of and behind
the vehicle and stop the vehicle in good time if
necessary.

Switch off the ACC if you suspect that the radar
sensor has been damaged or its position has
been altered. This can help to prevent further
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
the system or cause it to be switched off .
• Repair work on the radar sensor will require
special knowledge and tools. Volkswagen rec­

this purpose.
• Remove snow with a brush, and remove ice
preferably with a solvent-free de-icer spray. <1

When the adapt ive cruise control (ACC) is switch­
ed on, the green indicator lamp f) in the instrument
c
luste r lights up, and the speed memory and the
status
of the adaptive cruise contro l are shown in
the disp la y ~Fig. 165.
Conditions for starting the adaptive cruise
control
• The selector lever must be in position D or S or
be in the Tiptron ic gate. A forward gear, but not 1st
gear , must be selected
in the manu al gearbox .
• In vehicles with a manual gearbox , the actual
speed should be minimum 30 km /h (18 mph) if no
speed is stored .
Controlling speed
When switched on, the speed can be stored and
set. The stored speed can vary from the speed
ac­
tually
being driven if the distance is b ein g act ively
controlled.
Action
The system is switched on. No speed has yet
been stored and the speed is not yet being con-
trolled.
This sw itches between the CCS and the speed
limiter ~page 222 .

situations
J""'("'n First read and observe the Introductory
L-.kJ.l ir"'formation and safety warnings & on
page 226.
The adapttve cruise contro l (ACC) should be
s it c hed off in the following situations due t o sys­
tem limitations -~:
• When turning off roads. driving around round­
abouts, narrow curves. joining motorways, exiting
from motorways or driving through road works, to
prevent th e vehicle from unnecessarily accelerat­
ing to the set speed in these situations
• When driving through a tunnel as this situation
could impair the system function.
• On roads with more than one lane, if other vehi­
cles are driving more s lowly in the fast la ne . The
slower vehicles in the other lane would be o ve rtak­
en from the right side in this case.
• In heavy rain, snow or spray as vehicles tra ve l­
ling
ahead cannot be monitored sufficiently or
maybe cannot be monitored a t all.
Special driving situations
A WARNING
Failure to switch off the ACC in the above ­
mentioned situations can cause acciden ts
and result in serious injuries.
• Switch off the ACC in critical driving situa.
tions.

~ trol in the above-mentioned situations can
cause a violation of legal requirements. <

The adaptive cruise control (ACC) has physical
and system-rel ated limits . As such, certain ACC
system reactions may occur, from the driver's per-
232 While driving
spective , unexpectedly or with some delay. You
should therefore always be prepared to take full
control of the vehicle if necessary .

Stationary phase (only vehicles with
autornatic gearbox)
If the adap tive cruise control has decele ra t d the
vehicle to a standstill, the adapt.ive cruise contr o l
will not be switched off automatically wh en the
brake pedal is depressed .
The electronic parking brake will be activated auto4
matically and the adap tive cruise control will be
switched off if one of the following situations occurs
while the vehicle is stationary:
• The safety be lt is unfastened .
• The driver's door is opened.
• The ignition is switched off.
• The stationary phase lasts longer than approxi4
mately 3 minutes .
Driving off after a stationary phase (only
vehicles with automatic gearbox)
After a stationary phase, the adaptive cruise con­
trol can start the vehicle moving automatically as
soon as the vehicle in front begins to move again.
Overtaking
If the turn signal is activated when starting an over­
taking manoeuvre , the adaptive cruise control ac­
celerates the vehicle automatically and thus re­
duces the distance to the vehicle in front.
If you move your vehicle into the overtaking lane
and there is no vehicle ahead of you , the ACC will
automatically increase the speed to your set level
and maintain it.
Acceleration can be stopped at any point
by de­
Pressing the brake pedal or pressing the @ button
on the multifunction steering wheel ~page 229.
When driving through bends
While dr iving through bends, the radar sensor may
sometimes lose the ve hicle travelling ahead or
rnay r eac t to a ve hicle in the next lane
; Fig. 169 A. In such situations, the vehicle might
.
ecel e rate unnec essarily or not react to the veh icle
