2021 VOLKSWAGEN T-ROC cruise control

If automatic deceleration by ACC is not sufficient, ACC will request you to brake additionally by a
corresponding message on the instrument cluster. In addition, the red warning lamp lights up
and an acoustic warning is given. Brake immediately!
Radar sensor
ACC 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.

WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only
within the limits of the system. Never let the extra convenience tempt you into taking safety risks
when driving. Careless or unintentional use of the Adaptive Cruise Control (ACC) can cause accidents
and lead to serious injury. 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.
Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due
to snow, ice, wet roads, loose chippings, or on flooded roads.
Never use the ACC offroad or on non-surfaced roads. The ACC is designed for use on surfaced roads
only.
The ACC will not react to stationary vehicles.
The ACC will not react to persons, animals or vehicles crossing or approaching in the same lane.
Brake immediately if speed reduction by ACC is not sufficient.
Brake immediately if a request to brake appears on the instrument cluster display.
Brake if the vehicle starts rolling unintentionally after a request to brake.
Be prepared to control the speed yourself at all times.
Special driving situations

Fig. 118 On the instrument cluster display: slower vehicle detected in the left-hand lane (illustration).

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
Persons.
Animals.
Stationary vehicles.
Crossing or oncoming vehicles.
Other stationary obstacles.
If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise
control and this vehicle turns off the road or changes lane, the ACC will not react to the stationary
vehicle ⇒ Fig. 120  .
Bends
The radar sensor always measures straight ahead. For this reason, vehicles may be incorrectly
detected or vehicles driving ahead not detected in tight bends ⇒ Fig. 119  .
Vehicles outside the sensor range
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. motorbikes
⇒ Fig. 119  .
Vehicles that change into your lane directly in front of your vehicle ⇒ Fig. 120  .
Vehicles with bodies or attachments that project beyond the vehicle.

WARNING
If you use ACC in the above situations, this can result in accidents and serious injuries as well as
violation of legal regulations.
Switching ACC on and off

Traffic Jam Assist is an extension of the lane keeping system (Lane Assist) for vehicles with DSG ® and
combines its functions with the Adaptive Cruise Control (ACC). Please therefore read both these
chapters and observe the information about the system limits and warnings.
Traffic Jam Assist function
Traffic Jam Assist can maintain a time interval set by the driver to a vehicle in front and help the
vehicle to stay in lane ⇒ .
The system automatically controls acceleration, braking, steering and, if required, will decelerate to
a stop behind a vehicle that is stopping, and then pull away again automatically.
Use Traffic Jam Assist only on motorways and good main roads. Do not use Traffic Jam Assist in
urban traffic.
Switching Traffic Jam Assist on and off
Traffic Jam Assist is switched on and off together with the adaptive lane guidance of the lane
keeping system in the Infotainment system ⇒ Vehicle settings menu .
Traffic Jam Assist can also be switched off together with the lane keeping system via the button for
driver assist systems ⇒ Button for driver assist systems .
Technical requirements for using Traffic Jam Assist
The lane keeping system is switched on and active together with adaptive lane guidance ⇒ Driving
with the lane keeping system .
Adaptive Cruise Control (ACC) is switched on and active ⇒ Switching ACC on and off .
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. 123① .
The speed is under 60 km/h (35 mph).
Traffic Jam Assist is not active (indicator lamp for the lane keeping system lights up yellow)
As soon as one of the conditions indicated in ⇒ Technical requirements for using Traffic Jam Assist  is
no longer fulfilled.
If one of the conditions for the proper functioning of the lane keeping system is no longer fulfilled
⇒  .
If one of the conditions for the proper functioning of the Adaptive Cruise Control (ACC) is no longer
fulfilled ⇒ Limits of ACC .
Switch off Traffic Jam Assist in the following situations
Traffic Jam Assist should always be switched off in the following situations due to system limitations:
When a high level of concentration is required by the driver.
Very sporty driving.
In poor weather conditions, e.g. snow or heavy rain.

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.

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

Accessories, modifications, repairs and renewal of parts
Accessories and replacement parts
Volkswagen recommends that you seek advice from a Volkswagen dealership before purchasing
accessories, replacement parts or servicing materials, e.g. if the vehicle is to be retrofitted with
accessories or if parts need to be replaced. Volkswagen dealerships can recommend accessories,
replacement parts and service fluids suitable for your requirements. They can also provide
information regarding official regulations.
Volkswagen recommends that you use only approved Volkswagen accessories and Volkswagen
Genuine Parts®. These parts and accessories have been specially tested by Volkswagen for
suitability, reliability and safety. Volkswagen dealerships are also qualified to install them correctly.
Although the market is constantly scrutinised, Volkswagen cannot assume responsibility for the
reliability, safety and suitability of products Volkswagen has not approved. Volkswagen can
therefore assume no responsibility for these parts even if they have been approved by an official
testing agency or are covered by an official approval certificate.
Any retrofitted equipment which has a direct effect on the control of the vehicle must be approved
by Volkswagen for use in your vehicle and bear the e mark (the European Union's approval symbol).
These devices include cruise control systems or an electronically controlled suspension.
Any additional electrical components fitted that do not serve to control the vehicle itself must bear
the mark (manufacturer conformity declaration in the European Union). Such devices include
refrigerator boxes, computers and ventilator fans.

WARNING
Incorrectly performed repairs or modifications to your vehicle can impair the effectiveness of the
airbags and cause malfunctions, accidents and fatal injury.
re or position objects, e.g. telephone holders, in the deployment zone of the airbags
since these objects can cause serious or fatal injuries if the airbags are triggered.
Repairs and technical modifications
Repairs and technical modifications must always be carried out according to Volkswagen
specifications⇒ .
Unauthorised modifications to the electronic components or software in the vehicle may cause
malfunctions. As the electronic components are linked together in networks, these faults may
indirectly affect the operation of other systems. This can seriously impair safety, lead to excessive
wear of components, and also invalidate the type approval for the vehicle.
