2014 SKODA OCTAVIA brake sensor

Hydraulic Brake Assist (HBA)Read and observe
on page 138 first.
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by the very quick operation of the brake pedal. To ach-
ieve the shortest possible braking distance, the brake pedal must be applied
firmly until the vehicle has come to a complete standstill.
The HBA is automatically switched off when the brake pedal is released.
Hill Hold Control (HHC)
Read and observe
on page 138 first.
HHC allows you, when driving on slopes, to move your foot from the brake
pedal to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is always active on slopes when in forward or reverse start off.
Multi-collision brake (MCB)
Read and observe
on page 138 first.
The MCB helps to decrease speed after a collision through automatic braking
interventions and to stabilize the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
A head-on or side collision occurred.
The impact speed was higher than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.
Trailer stabilisation (TSA)
Read and observe
on page 138 first.
The TSA helps the combination stable in situations where the trailer sways
and then the whole trailer combination.
TSA brakes the individual wheels of the towing vehicle in order to damp the
rocking motion of the entire vehicle combination.
The following conditions are required for the correct TSA function. The trailer was shipped from the factory or purchased from the ŠKODA
genuine accessories.
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The parking aid is activated.
The speed is higher than approx. 60 km/h.
The activated TSA is shown by the fact that after switching on the ignition, the
indicator light  in the instrument cluster lights up for about 2 seconds longer
than the indicator light .

The parking aid (hereinafter referred to only as system) draws attention via
acoustic signals or the Infotainment display when manoeuvring around obsta-
cles in the vicinity of the vehicle.
The system uses ultrasound waves to calculate the distance between the
bumper and an obstacle. Depending on the vehicle equipment, the ultrasonic
sensors are located in the back or in the front bumper » Fig. 139 on page 141 .

This is only possible within the range which is permitted by the power output
and braking power of the engine.WARNINGIf the engine power or engine braking effect is insufficient to maintain the
set speed, the driver must take control of vehicle operation.

Automatic control interruption
Automatic control interruption occurs if any of the following conditions are
met.
› The brake pedal is operated.
› When one of the brake assist systems (e.g. ESC) intervenes.
› Through an airbag deployment.
WARNING■
Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.
Note
During control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set

Adaptive cruise control (from here on referred to only as ACC) can maintain the
set speed or the proximity to the vehicle ahead consistently, without the need
to operate the gas or brake pedals.
The state in which the ACC maintains the speed or the proximity is described
as control from here on. 
149Assist systems

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

WARNINGThe sensor may not be able to distinguish all objects correctly under certain
circumstances. You should therefore not use ACC in the following cases -
risk of accidents!■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

Control is inactive (the numbers of the speed indications are small and of a
grey color).
Control activated - no vehicle detected.
Control deactivated - no speed stored.
Control active - vehicle is detected (the figures of the speed indications
are displayed larger or are highlighted).
The ACC can consistently maintain the set speed of 30-160 km/h, as well as
the proximity to the vehicle ahead ranging from a very small to a very long
time interval.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
If the delay of the ACC is insufficient in relation to the vehicle in front, in the
instrument cluster, the warning light  lights up and the display shows the
following message.
Apply the brake!
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.1234ABCD151Assist systems

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

Towing a trailer
When towing a trailer, the ACC control will be less powerful. The manner of
driving should therefore be adapted to this limitation.

Read and observe and on page 155 first.
The system support is provided in the following manner.
› Alerts you about a dangerous proximity to the vehicle ahead.
› Warns you of an impending collision.
› Prepares the brakes for emergency braking prior to a detected danger.
›Assists with a brake action triggered by the driver.
› If the driver fails to respond to a detected danger, automatic braking is per-
formed.
The system can work only if the following basic conditions are met. The system is activated.
TCS is enabled » page 138, Braking and stabilisation systems .
The vehicle is traveling forwards at a speed of more than approx. 5 km/h.
Note
The system can be impaired or may not be available, for example when driving
in “sharp ”curves or with an ESC engagement » page 138.
proximity warning (dangerous proximity)
Read and observe
and on page 155 first.
If a safe distance to the vehicle ahead is not maintained, the display of the in-strument cluster shows the symbol 
» Fig. 155 on page 156 -
 .
Immediately increase the proximity if the current traffic situation allows you
to do so!
The proximity at which the warning is displayed depends on the current speed.
The warning may occur when driving between about 60 km/h and 210 km/h.
Warning and automatic braking
Read and observe
and on page 155 first.
Emergency braking at low speed
In a driving speed range of approx. 5 km/h to approx. 30 km/h, the automatic
braking action is not preceded by a warning. In the event of an immediate risk
of impact, automatic braking is carried out with the breaking force increasing
in stages.

ing. 
156Driving

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.
