WARNING■The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
WARNING■ The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
CAUTION
The control may automatically switch off when some brake assist systems (e.g.
ESC) intervene, when the maximum permissible engine speed is exceeded, etc.
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the elec-
trically connected trailer, the ACC becomes unavailable.
Radar sensorFig. 148
Mounting location of the radar
sensor
Read and observe and on page 150 first.
The radar sensor » Fig. 148 (From here on referred to as sensor) is used to as-
sess the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagnetic waves.
The sensor function may be impaired in the events of one of the following.
› The sensor is covered by mud, snow or debris, for example.
› The sensor or its immediate surroundings are covered by other objects, for
example, a sticker is attached.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or does not have “visibility” for any other reason, the fol- lowing message appears in the instrument cluster display » page 155.
WARNING■
If you suspect that the sensor is damaged, deactivate the ACC. Have the
sensor checked by a specialist garage.■
The sensor can become misaligned by collisions or by damage to the front
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to an impairment of the ACC function - risk of accidents! Have the sensor
checked by a specialist garage.
■
The area in front of and around the sensor must not be covered with
stickers, additional lights or similar items. This can lead to impaired function
of the sensor - risk of accidents!
150Driving
Note■If the proximity is changed in infotainment, the change will only come into
effect after a subsequent activation of the ACC.■
The proximity is dependent on the speed. The higher the speed, the greater
the proximity to the vehicle ahead.
■
On wet roads, a longer time interval to the vehicle ahead should always be
selected than on dry roads.
Special driving conditions
Fig. 152
Special conditions: Cornering / narrow vehicles or vehicles travel-
ling side by side
Fig. 153
Special conditions: Lane changes of other vehicles / stationary
vehicles
Read and observe
and on page 150 first.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adja-
cent lane » Fig. 152 -
. Your own vehicle is regulated with respect to this ve-
hicle and will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever .
» Fig. 151 on page 152 .
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the ra-
dar sensor until they are within the sensor's range » Fig. 152 -
.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 153 -
do not
have to be detected by the radar sensor in time. The result may be a delayed
ACC response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehi-
cle, » Fig. 153 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and stop the vehicle by applying the foot
brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is
stored) and the indicator is activated, the ACC interprets this situation as
meaning that the driver intends to overtake. The ACC automatically acceler-
ates the vehicle, thereby reducing the proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the
ACC accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 151 on page 152 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or over-
taking such a vehicle. 154Driving
The pre-warning display can occur in the following situations.› If there is a risk of collision with a moving obstacle at a driving speed range
of approx. 30 km/h to approx. 210 km/h.
› If there is a risk of collision with a stationary obstacle at a driving speed
range of approx. 30 km/h to approx. 85 km/h.
When the advance warning is issued, the brake pedal must be pressed or the
moving obstacle avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake Support
If the driver does not brake sufficiently in the event of an impending collision,
the system automatically increases the braking force.
The brake support only occurs as long as the brake pedal is being firmly press-
ed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by means of a steering intervention.
Activating/deactivating
Read and observe
and on page 155 first.
The function is automatically activated each time the ignition is switched on.

The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 156
Engine is automatically switched
off / automatic engine cut off is
not possible
Read and observe on page 158 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If, after stopping the vehicle, the check icon
» Fig. 156 appears on the dis-
play, then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Information about the current status of the system can be displayed in the In-
fotainment display » operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
Note
■
If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.

Further information on automatic transmission
Engine shut down takes place when the selector lever is in positions P, D/S , N
and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after
you release the brake pedal. The engine starts automatically by pressing the
gas pedal or by moving the selector lever into a different mode and releasing
the brake pedal.
If the engine is off due to the automatic and the selector lever is put to the R
position then the automatic starts the engine.
If the gear selector is moved from position R to the position D/S or N the vehi-
cle must reach a speed of more than 10 km / h before the automatic engine
shutdown starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 158 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle begins to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

Function
162
ProActive passenger protection (From here on referred to only as system) in-
creases passenger protection in the front seats in situations that could lead to
vehicle impact or overturning.
WARNING■ The increased safety by ProActive passenger protection must not tempt
you to take greater risks than otherwise – risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.

Applies to Octavia RS, Octavia RS.
161Assist systems
NoteThe system component service life is monitored electronically. Further infor-
mation » page 38 , Security systems .
Function
Read and observe
on page 161 first.
The system is activated whenever the ignition is switched on, and is ready tointervene automatically under the following conditions.
The engine is running.
The vehicle moves at a speed of more than 30 km/h.
In critical driving situations (e.g. during emergency braking or a sudden change
in direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
› The front passenger's and driver's seatbelts, if worn, are automatically
ten-
sioned closely over the body.
› The windows in the side doors (if open) are automatically closed up to a gap
of about 5 cm from the edge.
› The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.
The first level of protection can be deactivated by one of the following meas-
ures.
› Deactivation of the system in Infotainment
» Operating instructions for Info-
tainment , chapter Vehicle settings (CAR button) .
› Deactivation of TCS
» page 139.
› Selecting the driving mode Sport
» page 160.
Provided that the driving mode Sports is not selected, the system is activated over the two levels of protection after switching the ignition off and on again.
The second level of protection
The system intervenes only if the situation is evaluated as critical, such as in
panic braking at high speeds.
This level of protection cannot be deactivated.
Note
If the front passenger front airbag is deactivated » page 21 the belt tensioning
function for the front passenger seat is switched off.

Lane Assist (From here on referred to only as the system), helps to keep the
vehicle within the lane.
The system detects the boundary lines of a lane using the camera » Fig. 159.
When the vehicle approaches a detected line between lanes, the system
makes a light movement of the steering wheel in the opposite direction to the
boundary line. This corrective steering intervention can be overridden at any
time.
162Driving
WARNING■The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
Lane Assist can help you keep the vehicle within the lane. However, it
does not steer the vehicle for you. The driver retains full responsibility for
steering at all times.
■
Some objects on the road may be incorrectly detected as lines. As a re-
sult, an incorrect steering intervention may take place.
WARNINGThe detection capability of the camera may be limited by various external
influences. In such cases, the assistant may not detect the line between
two lanes at all or not properly. The detection capability of the camera may
be restricted in the following situations, for example.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When driving around “sharp” bends.
■
The camera is blinded by the sun.
■
The camera is blinded by the oncoming traffic.
■
The viewing range of the camera is impeded by a vehicle traveling ahead.
■
The camera viewing range is obstructed by an obstacle.
CAUTION
Do not attach any stickers or similar objects to the windscreen to avoid impair-
ing the functions of the Assist system.
Note
■ The system is designed for driving on motorways and roads with adequate
longitudinal markings.■
The system can detect both continuous and broken lines.
