2021 VOLKSWAGEN T-ROC brake light

WARNING
If you do not maintain the minimum distance to a vehicle in front and the difference in speed
between the vehicle in front and your own vehicle is so great that the braking action of the ACC is
insufficient, you are in danger of colliding with the vehicle in front. The braking distance is also
longer in rain and winter road conditions.
ACC may not be able to detect all driving situations correctly.
Always be prepared to brake the vehicle yourself.
Speed and distance control are overridden when you press the accelerator. ACC does not brake
automatically in this case.
Observe any country-specific regulations relating to the minimum distance.
Always set a larger distance in wet or snowy conditions or when visibility is poor.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .

Area monitoring system (Front Assist)
Introduction
This chapter contains information on the followingsubjects:
⇒ Warning levels and braking intervention 
⇒ Limits of Front Assist 
⇒ Pedestrian Monitoring 
⇒ Operating the area monitoring system (Front Assist) 
⇒ Troubleshooting 
The area monitoring system (Front Assist) with City Emergency Braking System and Pedestrian
Monitoring can help to avoid accidents.
Within the limits of the system, Front Assist can warn the driver about imminent collisions, prepare
the vehicle for emergency braking, assist with braking, and initiate automatic braking. The warning
time varies depending on the traffic situation and driver behaviour.
Front Assist is not a substitute for the full concentration of the driver.
Driving with Front Assist
You can cancel the automatic braking interventions of Front Assist by steering or pressing the
accelerator.
Automatic braking
Front Assist can decelerate the vehicle to a standstill. The vehicle will then not be held permanently.
Depress the brake pedal.

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).

Emergency Assist detects a lack of activity on the part of the driver and can keep the vehicle in lane
automatically, or brake the vehicle to a standstill if required. The system can therefore actively help
to prevent an accident.
Emergency Assist is an extension of the lane keeping system (Lane Assist), and combines these
functions with the Adaptive Cruise Control (ACC). Please therefore read both these chapters and
observe the information about the system limits and warnings.
Description
If there is no driver activity, Emergency Assist prompts the driver to take control of the vehicle again
by visual and acoustic warnings and by braking jolts.
If the driver remains inactive, the system automatically controls the accelerator, brake and steering
to slow the vehicle down and keep it in lane ⇒ . If there is sufficient stopping distance, the system
decelerates the vehicle to a complete stop and switches on the electronic parking brake
automatically ⇒ Operating the electronic parking brake .
When Emergency Assist is actively controlling the vehicle, the hazard warning lights are switched on
and the vehicle performs slight snaking movements within its lane to warn other road users.
The hazard warning lights can be deactivated by pressing the accelerator or brake, by making a
steering intervention or, depending on the situation, by pressing the button for the hazard warning
lights.
When Emergency Assist has been triggered, the system is not available again until the ignition has
been switched off and then back on.
Prerequisites
The lane keeping system and ACC are switched on.
The selector lever is in position D/S or in the Tiptronic gate.
The system has detected a lane marking on both the right and left sides of the vehicle ⇒ Fig. 123 .
Switching Emergency Assist on and off
Emergency Assist is activated automatically when the lane keeping system ⇒ Driving with the lane
keeping system  is switched on.

WARNING
The intelligent technology used in Emergency Assist cannot overcome the laws of physics, and
functions only within the limits of the system. The driver is always responsible for controlling the
vehicle.
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.
Emergency Assist cannot always prevent accidents and serious injuries on its own.

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.
