Get Driving -> Adaptive Cruise Control (ACC) Guide for Volkswagen T-Roc SUV First Generation (2017-2025)

The Adaptive Cruise Control (ACC) maintains a constant speed that you have set. If the vehicle approaches a vehicle in front, the ACC

automatically adapts the speed so that a distance you have selected is maintained.

Does the vehicle have ACC?

The vehicle is equipped with ACC. if the

button is present on the left-hand side of the multifunction steering wheel.

Speed range

You can set a speed between 20 km/h (15 mph) and 210 km/h (130 mph). Depending on equipment and country, the maximum speed

that can be set may be lower.

Driving with ACC

You can override a control intervention by the ACC system at any time. Cruise control will be stopped if you brake. If you accelerate,

control will be interrupted while you are accelerating and then resumed with the set speed.

The intervention by the ACC system is less dynamic when towing a trailer.

Driver intervention prompt

If automatic deceleration by the ACC system is not sufficient or the system limits have been reached, the ACC system 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. Take over control of the vehicle and be prepared to brake.

WARNING

ACC is not a substitute for the full attention of the driver and operates only within the limits of the system. ACC cannot detect all

driving situations and may not react or may react with a delay or in an undesired way. If you do not pay due attention, there is a risk

of accidents and serious or even fatal injuries.

● Always pay due attention and do not rely exclusively on the system. The driver is always responsible for all driving tasks.

● Observe the system limits (→ Adaptive Cruise Control (ACC)).

● Adapt your speed and the distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.

● Take control of the vehicle immediately if requested to do so by a prompt on the instrument cluster display or if the speed

reduction by ACC is not sufficient.

● Brake if the vehicle starts moving unintentionally, e.g. after a driver intervention prompt.

The functions described below are dependent on the equipment level and are not available in all countries.

Predictive cruise control system

If the vehicle is equipped with the Dynamic Road Sign Display function, ACC can predictively adapt the vehicle speed to detected speed

limits and the course of the road ahead .

Overtaking

If you indicate left (left-hand traffic: indicate right) to overtake, ACC can accelerate the vehicle and thus reduce the distance from the

vehicle in front. Your set speed will not be exceeded.

If ACC does not detect any vehicle in front after you have changed lane, ACC will accelerate the vehicle up to the set speed.

Stop-and-go traffic

ACC can brake vehicles with an automatic gearbox to a standstill and hold them stationary for a few seconds. ACC remains active and

the instrument cluster display shows ACC ready. During this time the vehicle will move off again automatically as soon as the vehicle in

front moves off.

After this time, the vehicle will automatically release the brakes. The vehicle will be free to roll and ACC control will be cancelled.

Extend readiness to drive:

—Depress the brake pedal.

ACC remains active as long as the brake pedal is depressed. When you take your foot off the brake pedal, ACC remains ready to pull

away for a few seconds.

—Press the

button.

Readiness to move off is prolonged for a few seconds.

The readiness to move off is ended if the driver’s seat belt is unfastened.

WARNING

If the message ACC ready to start is shown on the instrument cluster display and the vehicle in front moves off, your vehicle will

move off automatically. In some cases, obstacles in the vehicle’s path may not be detected. This can result in serious injury and

accidents.

● Always check the road ahead before moving off and brake the vehicle if necessary.

Inside Overtaking Prevention System

On the instrument cluster display: slower vehicle detected in

the left-hand lane (illustration).

Vehicles with Inside Overtaking Prevention System: If ACC detects a slower vehicle in the left-hand lane (left-hand traffic: in the right-

hand lane), ACC will brake the vehicle gently within the system limits and can therefore prevent a prohibited overtaking manoeuvre.

The function is active from a speed of around 80 km/h (around 50 mph).

Vehicles without Inside Overtaking Prevention System: When driving on a multi-lane road, cancel control if vehicles in the overtaking

lane are driving more slowly.

Limits of the sensors

ACC detects driving situations by means of the radar and ultrasound sensors in the front of the vehicle and the camera behind the

windscreen. The range of the radar sensor is up to approximately 120 m (around 400 ft).

WARNING

If you use ACC in driving situations that are outside the system limits, this could result in accidents and serious injuries as well as

violations of legal regulations.

● Observe the limits of the sensors (→ Sensors) and cancel control in the specified situations.

Objects that cannot be detected

ACC detects only vehicles that are moving in the same direction or stationary. The following are not detected:

—Persons.

—Animals.

—Crossing or oncoming vehicles.

—Other stationary obstacles.

Stationary vehicles

Stationary vehicle.

ACC reacts to stationary vehicles to a limited extent up to a speed of around 60 km/h (around 37 mph), provided a stationary vehicle is

detected and your own vehicle can be comfortably braked behind the stationary vehicle, subject to the system limits of the ACC. ACC

does not perform emergency braking → Fig. 1.

The response to stationary vehicles depends on the vehicle equipment and is not available in all countries.

Left-hand side of the multifunction steering wheel.

Switching on

1. Press the

button.

ACC is not yet performing a control intervention.

Starting control

1. While driving forwards, press the

button.

ACC stores the current speed and maintains the set distance. If the current speed is outside the defined speed range, ACC will set

the minimum speed when driving more slowly than the limit or the maximum speed when driving faster than the limit.

Relevant brake support systems are also activated (→ Brake support systems).

The following indicator lamps light up, depending on the driving situation:

ACC has taken control; no vehicle detected ahead.

ACC has taken control; vehicle detected ahead.

Cancelling system control

1. Briefly press the

button.

depress the brake pedal while driving.

The indicator lamp corresponding to the driving situation lights up grey, the speed and distance remain stored.

If a relevant brake support system is deactivated, control is automatically interrupted (→ Brake support systems).

Resuming control

1. Press the

button.

ACC adopts the last set speed and last set distance. The instrument cluster display shows the set speed and the indicator lamp

corresponding to the driving situation lights up.

Switching off

1. Press and hold the

button.

The set speed is deleted.

Changing to the speed limiter

1. Press the

button.

2. Select the speed limiter on the instrument cluster display.

ACC is switched off.

Depending on equipment, the

button is either on the multifunction steering wheel or on the turn signal lever.

Setting the distance

On the instrument cluster display: set distance for control

(illustration).

You can set the distance in five steps from very small to very large:

1. Press the

button.

2. Press the or button.

press the

button repeatedly until the required distance is selected.

The instrument cluster display shows the chosen setting → Fig. 1 1 . Please observe any country-specific regulations for the

minimum distance.

Control always starts at the level that the respective user had set at the end of the last trip.

If the ACC has not taken control, the set distance and vehicle are not highlighted on the instrument cluster display.

Adjusting the speed

You can adjust the stored speed within the defined speed range by means of the buttons on the multifunction steering wheel:

+ 1 km/h (1 mph):

Press the

button, only when ACC is active.

- 1 km/h (1 mph):

Press the

button, only when ACC is active.

+ 10 km/h (5 mph):

Press the button. The first time it is pressed, it jumps to the next higher ten (km/h) or five (mph) increment.

- 10 km/h (5 mph):

Press the button. The first time it is pressed, it jumps to the next lower ten (km/h) or fives (mph) increment

Press and hold the or button to continuously change the stored speed.

WARNING

ACC cannot detect all driving situations correctly. If you do not maintain the minimum distance to the vehicle in front or if the

difference in speed between the vehicle in front and your own vehicle is so great that the braking action of ACC is insufficient, you are

in danger of colliding with the vehicle in front. This can cause serious injuries or death.

● Always be prepared to brake the vehicle yourself.

● Press the accelerator to override Adaptive Cruise Control. 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.

Setting the system behaviour

You can influence how dynamically ACC reacts:

—Vehicles with driving profile selection:

Set preferred driving profile.

—Vehicles without driving profile selection:

Select the desired gearbox program in the Assist systems menu of the Infotainment system.

Some settings can be stored in the user accounts of the personalisation function and therefore change automatically when the

user account changes.

ACC not available

The indicator lamp lights up yellow. A message will also appear on the instrument cluster display.

—The radar sensor is dirty. Clean the radar sensor (→ Vehicle care).

—The view 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 view of the radar sensor is impaired by add-on parts, number plate holders with trim frames or stickers. Keep the area around

the radar sensor free (→ Accessories and replacement parts).

—The radar sensor has been displaced or damaged, e.g. due to damage to the front of the vehicle. Check whether damage is visible

(→ Accessories and replacement parts).

—Fault or malfunction. Switch off and restart the engine.

—The brakes have overheated, control was cancelled automatically. Allow the brakes to cool down and check their functionality again.

—If the problem persists, go to a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.

Depending on the malfunction, additional information may be displayed in the vehicle status (→ Vehicle settings menu).

Control cannot be started

Make sure that the following conditions are met:

—Vehicles with a manual gearbox: A forward gear other than 1st gear has been engaged and the speed is at least 25 km/h (16 mph).

—Vehicles with an automatic gearbox: A position has been selected for driving forward.

—The brake lights on the vehicle are working.

—The brake lights on the electrically connected trailer are in working order.

—ESC is not performing a control intervention.

—If control is to be started while the vehicle is stationary, depress the brake pedal. Otherwise, do not depress the brake pedal.

Unusual noises during automatic braking

This is normal and is not a fault.

The predictive cruise control adapts the vehicle speed to detected speed limits and the course of the road ahead, e.g. bends,

junctions, roundabouts.

The predictive cruise control is an extension of ACC and makes use of Dynamic Road Sign Display and navigation data provided in the

Infotainment system.

The predictive cruise control function is dependent on the equipment level and is not available in all countries.

WARNING

The predictive cruise control system is not a substitute for the full attention of the driver and operates only within the limits of the

system. The predictive cruise control system cannot detect all applicable speed limits and may not react or may react with a delay or

in an undesired way. If you do not pay due attention, there is a risk of accidents and serious or even fatal injuries.

● Always pay due attention and do not rely exclusively on the system. The driver is responsible for the stored vehicle speed at all

times.

● Observe the system limits (→ Predictive cruise control system).

● Ensure that your speed is always appropriate for the current visibility, weather and road/traffic conditions.

● Keep the navigation data up-to-date.

● Always observe the maximum speed limit.

● Please note that the speeds regulated by the system do not necessarily correspond to your driving style.

Also observe the system limits and the information for ACC.

The system also uses navigation data even if the vehicle does not have a navigation system. Keep the navigation data up-to-

date (→ Navigation). If you have any questions, please contact a suitably qualified workshop. Volkswagen recommends using

an authorised Volkswagen repairer.
