sensor VOLKSWAGEN T-ROC 2021 Owner´s Manual

The brake pedal will feel harder during an automatic braking operation.
Radar sensor
Front Assist detects driving situations by means of the radar sensor at the front of the vehicle
⇒ Front view . The radar sensor has a range of up to approximately 120 m.
Functions included in the system
The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle equipment)
are part of Front Assist and are automatically active when Front Assist is switched on.

WARNING
The intelligent technology used in Front Assist cannot overcome the laws of physics, and functions
only within the limits of the system. Never let the extra convenience afforded by Front Assist tempt
you into taking safety risks when driving. The driver is always responsible for braking in time.
If Front Assist issues a warning, brake your vehicle immediately depending on the traffic situation or
avoid the obstacle.
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 warnings and carry out unwanted braking interventions in certain
complex driving situations, e.g. at traffic islands.
Front Assist can issue unnecessary warnings and carry out unwanted braking interventions when its
function is impaired, e.g. if the radar sensor is dirty or its position has been changed.
Front Assist without Pedestrian Monitoring does not react to persons. In addition, the system does
not react to animals or to vehicles that are crossing or approaching in the same lane.
If you are unsure whether your vehicle possesses Pedestrian Monitoring, please enquire about this
at a qualified workshop before starting your journey.
Be prepared to take over control of the vehicle yourself at all times.
Warning levels and braking intervention
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Distance warning
The system detects when safety is endangered by driving too close to the vehicle in front. The
warning lamp lights up. Increase the distance.
Speed range: around 65 km/h (40 mph) to 250 km/h (155 mph).
Advance warning

The system is able to detect possible collisions with vehicles in front or pedestrians crossing in front
of the vehicle and prepares the vehicle for a possible emergency braking procedure.
A warning tone sounds and the red warning lamp lights up. Brake or take avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
Urgent warning
If the driver does not react to the advance warning, the system may initiate a short braking jolt in
order to draw attention to the increasing collision risk. Brake or take avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
Automatic braking
If the driver also does not react to the urgent warning, the vehicle can be braked automatically with
braking force that increases in several stages. The reduced speed means that it is possible to
minimise the consequences of an accident.
Speed range: around 5 km/h (3 mph) to 250 km/h (155 mph).
Braking intervention
If the system detects that the driver is braking insufficiently when there is a risk of collision, the
system can increase the braking force and help prevent a collision. The braking intervention takes
place only for as long as the brake pedal is pressed hard.
Speed range: around 5 km/h (3 mph) to 250 km/h (155 mph).
City Emergency Braking System
The City Emergency Braking System is part of Front Assist. If the driver does not react to a possible
collision, the system can also automatically brake the vehicle with increasing braking force without
any advance warning.
The red warning lamp lights up
Speed range: around 5 km/h (3 mph) to 30 km/h (20 mph).
Limits of Front Assist
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Front Assist is not available or its functions are restricted for a period of around 30 seconds (also
longer, depending on the driving situation) immediately after the vehicle is started.
Front Assist has physical and system-related limitations. You should therefore always be prepared to
take full control of the vehicle if necessary.
Delayed response
If the radar sensor is exposed to environmental conditions that impair sensor functioning, the
system may detect this only after a certain time. For this reason, possible functional restrictions may
be displayed only after a delay at the start of the journey and when driving ⇒ .

Objects that cannot be detected
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. vehicles
that are driving offset to your vehicle or motorbikes.
Vehicles that change into your lane directly in front of your vehicle.
Vehicles with bodies or attachments that project beyond the vehicle.
Oncoming vehicles or vehicles crossing your path.
Pedestrians who are stationary, moving towards the vehicle or moving in the same direction as the
vehicle.
Function limitations
In tight bends.
Driving in heavy rain, snow or heavy spray.
Driving in multi-storey car parks.
Driving on roads with embedded metal objects, e.g. railway tracks.
Reversing.
If TCS is switched off manually.
If ESC is taking corrective action.
If the radar sensor is dirty or covered.
If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to
the vehicle ⇒  .
If the vehicle accelerates hard or the accelerator is fully depressed.
In complex driving situations, e.g. at traffic islands.
In unclear traffic situations, e.g. vehicles ahead are braking heavily or turning off.
If there is a fault in Front Assist.
Switching off Front Assist
If the vehicle is used in a capacity other than driving in normal traffic, e.g. offroad.
If the vehicle is being towed or is loaded onto another vehicle.
If the radar sensor is covered temporarily by add-on parts, e.g. auxiliary headlights.
If the radar sensor is faulty.
After external force on the radar sensor, e.g. after a frontal collision.
In the event of multiple unwanted interventions.

WARNING
Failure to switch off Front Assist in the situations mentioned can result in accidents and serious
injuries.
Pedestrian Monitoring
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Pedestrian Monitoring can help to avoid accidents with pedestrians crossing the vehicle's path or to
mitigate the consequences of an accident.
The system gives a warning when there is a risk of collision, prepares the vehicle for emergency
braking, helps to brake the vehicle or performs an automatic brake intervention. In the event of an
advance warning, the warning lamp lights up in the instrument cluster
When Front Assist is switched on, Pedestrian Monitoring is active as part of Front Assist in a vehicle
speed range from approx. 5 km/h (3 mph) to 65 km/h (40 mph).
Pedestrian Monitoring is not available in all countries, depending on the vehicle equipment level.

WARNING
The intelligent Pedestrian Monitoring technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by the
Pedestrian Monitoring system tempt you into taking any safety risks when driving. The driver is
always responsible for braking in time.
If Pedestrian Monitoring issues a warning, brake your vehicle immediately depending on the traffic
situation or avoid the pedestrian.
Pedestrian Monitoring cannot prevent accidents and serious injuries on its own.
Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking
interventions in complex driving situations, e.g. on a main road that turns sharply.
Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking
interventions when its function is impaired, e.g. if the radar sensor is covered or its position has
been changed.
Be prepared to take over control of the vehicle yourself at all times.
Operating the area monitoring system (Front Assist)
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Front Assist and the advance warning (in some countries) are automatically switched on when you
switch on the ignition.
However, the system is not available or its functions are restricted for a period of around 30 seconds
(also longer, depending on the driving situation).

Volkswagen recommends that Front Assist and also the distance and advance warnings are switched
on at all times. Exceptions ⇒ Limits of Front Assist .
Switching on and off
Switch Front Assist on and off in the vehicle settings of the Infotainment system ⇒ Vehicle settings
menu .
Or: switch Front Assist on and off in the instrument cluster menus ⇒ Instrument cluster menus .
If you switch off Front Assist, the advance warning and distance warning will also be switched off.
The yellow indicator lamp lights up in the instrument cluster display. .
Setting the distance and advance warnings
Switch on Front Assist.
Switch the desired function on and off in the vehicle settings of the Infotainment system ⇒ Vehicle
settings menu .
Depending on the vehicle equipment, you can also set the warning time for the advance warning.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Front Assist is not available, the radar sensor does not have sufficient visibility.
The radar sensor is dirty. Clean the radar sensor ⇒ Vehicle care .
The visibility of the radar sensor is impaired due to the weather conditions, e.g. snow, or due to
detergent deposits or coatings. Clean the radar sensor ⇒ Vehicle care .
The visibility of the radar sensor is impaired by add-on parts, the trim frames of number plate
holders or stickers. Keep the area around the radar sensor free.
The radar sensor has been displaced or damaged, e.g. due to damage to the front of the vehicle.
Check whether damage is visible ⇒ Repairs and technical modifications .
Structural modifications have been made to the front of the vehicle.
The genuine Volkswagen badge is not used.
If the problem persists, switch off Front Assist and go to a qualified workshop.
Front Assist does not function as expected or is triggered unnecessarily several times.
The radar sensor is dirty. Clean the radar sensor ⇒ Vehicle care .
The system limits are not met ⇒ Limits of Front Assist .

If the radar sensor for the Adaptive Cruise Control (ACC) or the camera for the lane keeping system
is covered or moved, Emergency Assist may make unwanted braking or steering manoeuvres.
Emergency Assist does not react to persons, animals or vehicles crossing or approaching in the same
lane.

WARNING
If Emergency Assist is triggered unnecessarily, this can result in accidents and serious injuries.
If there is a malfunction in the Emergency Assist system, switch off the lane keeping system (Lane
Assist) ⇒ Driving with the lane keeping system . This will also switch off Emergency Assist.
Go to a qualified workshop and have the system checked. Volkswagen recommends using a
Volkswagen dealership for this purpose.
Blind Spot Monitor
Introduction
This chapter contains information on the followingsubjects:
⇒ Driving with the Blind Spot Monitor 
⇒ Troubleshooting 
Radar sensors monitor the area behind the vehicle. The system measures the distance and
difference in speed in relation to other vehicles and uses visual signals in the exterior mirrors to
inform the driver.
System limits
Use the Blind Spot Monitor only on surfaced roads.
The Blind Spot Monitor may not always interpret the traffic correctly in the following situations:
In tight bends.
When driving in the middle of two lanes.
When road lanes are of varying width.
At road crests.
In poor weather conditions.
Where there are special roadside structures, e.g. high or offset crash barriers.

WARNING
The intelligent technology used in the Blind Spot Monitor cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by the Blind

Spot Monitor tempt you into taking any safety risks when driving. Careless or unintentional use of
the Blind Spot Monitor can cause accidents and serious injuries. The system is not a substitute for
the full concentration of the driver.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Your hands should always be on the steering wheel so that you can steer at any time.
Pay attention to the indicator lamps in the exterior mirrors and in the instrument cluster display and
respond according to the commands.
Always pay close attention to the surroundings of the vehicle.
Never use the Blind Spot Monitor if the radar sensors are dirty, covered or damaged. These
conditions can impair the proper functioning of the system.
It may be hard to see the indicator lamp in the exterior mirror in direct sunlight.

Some settings can be saved in the user accounts of the personalisation function and can therefore
change automatically when the user account is changed ⇒ Personalisation .
Driving with the Blind Spot Monitor

Fig. 124 In the exterior mirrors: Blind Spot Monitor display.
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Switching on and off
Depending on the vehicle equipment, by means of the button for the driver assist systems ⇒ Button
for driver assist systems .
OR: using the Assist systems menu in the instrument cluster.
OR: with some equipment levels, in the Driver assistance menu in the Infotainment system
⇒ Vehicle settings menu .
When the Blind Spot Monitor is ready for operation, the yellow indicator lamp lights up once
briefly in the exterior mirrors.
This most recent system setting is retained even after the ignition has been switched off and on.

Function
When switched on, the Blind Spot Monitor is active from a speed of approx. 15 km/h (9 mph).
In the following driving situations, the yellow indicator lamp will light up in the corresponding
exterior mirror: ⇒ Fig. 124 
If your vehicle is being overtaken.
When overtaking another vehicle with a speed difference of up to approximately 10 km/h (6 mph).
No display will be shown if the takeover manoeuvre is much faster.
If a vehicle is detected in the blind spot and the turn signal is additionally activated in the direction
of the detected vehicle ⇒ , the yellow indicator lamp will flash.
In vehicles with the lane keeping system, the yellow indicator lamp will flash even if you do not
activate the turn signal when leaving your lane, provided that the lane keeping system is switched on
(Blind Spot Monitor Plus). The driver is warned by a corrective steering intervention when changing
lanes during a possible critical situation (information level, warning level). This also occurs when the
turn signal is activated for the corresponding direction. If the steering intervention is overridden by
the driver, the steering wheel vibrates to give an additional warning.
The quicker another vehicle approaches, the earlier there is a corresponding display in the exterior
mirror.
Automatic deactivation
The radar sensors for the Blind Spot Monitor will switch off automatically if, for example, the system
detects that a radar sensor is continuously covered. This can be caused by a layer of ice or snow in
front of the radar sensor, for example.
A text message will be shown on the instrument cluster display.
If the Blind Spot Monitor has been automatically deactivated, the system cannot be activated until
the ignition has been switched off and back on again.
The Blind Spot Monitor is automatically deactivated and cannot be activated when the factory-fitted
towing bracket is electrically connected to a trailer or similar ⇒ Trailer towing . Once a trailer is
electrically connected to the vehicle and the driver pulls away, a text message appears in the
instrument cluster display to inform the driver that the Blind Spot Monitor has been deactivated.
The Blind Spot Monitor will be automatically activated again when the trailer has been unhitched
from the vehicle. This applies if the function was previously activated. The Blind Spot Monitor must
be deactivated manually if you tow a trailer using a towing bracket that was not fitted at the factory.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Blind Spot Monitor is not working
The indicator lamp lights up yellow.
Go to a qualified workshop.

System fault
Clean the radar sensors or remove stickers or accessories from the radar sensors, mirrors and
bumper ⇒ Caring for and cleaning the vehicle exterior .
Check whether any damage is visible.
The system is not responding as expected
The radar sensors are dirty. The sensor visibility may be impaired by dirt and snow or also residue
from cleaning agents or coatings ⇒ Caring for and cleaning the vehicle exterior .
The prerequisites for system operation must be met ⇒ System limits .
The radar sensors are covered by water.
The vehicle is damaged in the area of the radar sensors, e.g. caused by parking collisions.
The detection ranges of the radar sensors are blocked by add-on parts, e.g. bicycle carriers.
Changes have been made to the paintwork in the area of the radar sensors or structural
modifications have been made, e.g. on the vehicle front end or the running gear.
Only Volkswagen-approved vehicle paints may be used on the rear bumper. Other vehicle paints can
restrict the function of the system or cause faults.
Tinting foils have been retrofitted on the side windows.
Parking and manoeuvring
Parking
Stopping and parking the vehicle
The actions should be carried out only in the given order:
Stop the vehicle on a suitable surface ⇒ .
Depress and hold the brake pedal until the engine has stopped.
Switch on the electronic parking brake ⇒ Electronic parking brake . The electronic parking brake is
switched on when the indicator lamp in the button ⇒ Fig. 125  lights up yellow and the indicator
lamp in the instrument cluster display lights up red.
On vehicles with a manual gearbox, either fully depress or disengage the clutch.
With an automatic gearbox, move the selector lever to position P.
Switch off the engine and take your foot off the brake pedal.
Turn the steering wheel slightly if necessary to engage the steering lock mechanism.
With a manual gearbox, select first gear for flat ground and uphill gradients, or reverse gear for
downhill gradients, and then release the clutch.
Please ensure that all occupants, in particular children, leave the vehicle.

Rear view camera system (Rear View) ⇒ Rear view camera system (Rear View) .
Park Assist ⇒ Park Assist .
The available systems vary according to the vehicle equipment level.
Limits of the parking systems
The sensors or cameras may not always be able to detect objects such as thin rails, fences, posts,
trees, very low or high obstacles and open or opening boot lids.
In some cases, dirt and ice on the sensors or cameras could be registered as an obstacle.
Limits of the rear view camera system
The rear view camera system shows only two-dimensional images on the screen. The lack of depth
of field means that potholes and protruding objects on the ground may only be detected with
difficulty, or may not be detected at all.
The system displays the orientation lines irrespective of the area surrounding the vehicle. There is no
automatic obstacle detection. Drivers must judge for themselves whether the vehicle will fit into the
parking space.

WARNING
The intelligent technology used in the parking systems cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by the
parking systems tempt you into taking any risks when driving. The parking systems cannot replace
the full concentration of the driver.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions.
Unintentional vehicle movements can cause serious injury.
Keep looking in the direction in which you are parking and at the relevant area surrounding the
vehicle.
Do not allow the displays in the instrument cluster and the images shown in the Infotainment
system to distract you from the traffic.
Always monitor the area around the vehicle as the parking systems will not always detect infants,
animals and objects.
The parking systems have blind spots in which obstacles and people are not registered.
External sources of sound and certain surfaces on objects and clothing may influence the signals of
the sensors. In certain circumstances, the systems will be unable to detect or properly detect people
and objects.
Certain objects, for example narrow posts or railings, may be difficult or impossible to see on the
screen because of its resolution or poor light conditions.
