The indicator lamp flashes:  
Turn the steering wheel to and fro.  
Switch the ignition off and then on again.  
Observe the messages on the instrument cluster display.  
Do not continue your journey if the indicator lamp still flashes after the ignition is switched on. Seek expert  
assistance.  
Introduction  
The cruise control system(CCS) helps to maintain a speed set by the driver.  
Speed range  
The cruise control system is available when driving forwards at speeds of approx. 20 km/h(around 15 mph) and  
above.  
Driving with the cruise control system  
You can exceed the stored speed at any time, e.g. to overtake. Control is interrupted for the duration of the  
acceleration manoeuvre and is then resumed with the stored speed.  
Displays  
When the cruise control system is switched on, the instrument cluster display shows the stored speed and the status  
of the cruise control system:  
Cruise control system switched on.  
or  
Cruise control system switched on, control intervention active.  
The indicator lamps are shown as small icons or are greyed out if the cruise control system is not regulating.  
The instrument cluster display shows--- if no speed is stored.  
Changing gear  
Cruise control is interrupted as soon as you press the clutch pedal and is resumed automatically after the gear  
change.  
Driving downhill  
Change to a lower gear before you drive downhill for an extended period. In this way you will make use of the engine  
braking effect and relieve the load on the brakes.  
WARNING  
Use of the cruise control system can lead to accidents and serious injuries if traffic does not allow you to drive at a  
safe distance at a constant speed.  
Never use the cruise control system in heavy traffic, if the distance to the vehicles in front is insufficient, on steep  
or winding roads, on slippery road surfaces e.g. due to snow, ice, wet roads, loose chippings, or on flooded roads.  
Never use the cruise control system when driving offroad or on unpaved road surfaces.  
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.  
Always switch cruise control off after use to avoid unintentional operation.  
It is dangerous to use a set speed that is too high for the prevailing road, traffic or weather conditions.

Introduction  
The speed limiter helps you to stop exceeding a selected speed.  
Speed range  
The speed limiter is available when driving forwards at speeds of approx. 30 km/h(around 20 mph) and above.  
Driving with the speed limiter  
You can interrupt the speed limiter at any time by depressing the accelerator all the way down until you meet  
resistance. As soon as the stored speed is exceeded, the green indicator lamp will flash and an acoustic warning may  
sound. The speed is stored in the memory.  
The speed control function switches back on automatically as soon as the speed drops back below the stored speed.  
Displays  
When the speed limiter is switched on, the instrument cluster display shows the stored speed and the status of the  
speed limiter:

or  
Speed limiter switched on, control active.  
The indicator lamps are shown as small icons or are greyed out if the speed limiter is not regulating.  
Driving downhill  
Change to a lower gear before you drive downhill for an extended period. In this way you will make use of the engine  
braking effect and relieve the load on the brakes.  
WARNING  
Always switch off the speed limiter after use to avoid unintentional cruise control.  
The speed limiter does not relieve the driver of their responsibility for the speed of the vehicle. Do not drive at full  
throttle if it is not required.  
Use of the speed limiter in adverse weather conditions is dangerous and can cause serious injury, e.g. through  
aquaplaning, snow, ice, or leaves. Use the speed limiter only when the road and weather conditions allow it to be  
used safely.

214  
Introduction  
The Adaptive Cruise Control(ACC) maintains a speed selected by the driver. If the vehicle approaches a vehicle in  
front, the ACC automatically adapts the speed so that a distance you have selected is maintained.  
Does my vehicle have the ACC function?  
The vehicle is equipped with ACC if you can make settings for ACC in the Assist systems menu in the Infotainment  
system.  
Speed range  
You can set a speed between 30 km/h(20 mph) and 210 km/h (130 mph). This speed range may differ in certain  
markets.  
Driving with ACC  
You can override the ACC at any time. Control will be cancelled if you brake. If you accelerate, the system will be  
interrupted for the duration of the acceleration process and will then continue again.  
Control by ACC is less dynamic when towing a trailer.  
Driver intervention prompt  
The ACC will send a message to the instrument cluster telling you to apply the brake if the ACC's automatic  
deceleration is insufficient, or if the system limits are reached. In addition, the red warning lamp lights up and  
an acoustic warning is given. Take control of the vehicle and be prepared to apply the brakes!  
Radar sensor  
ACC detects driving situations by means of the radar sensor at the front of the vehicle. The range of the radar sensor  
is up to approximately 160 m (around 520 ft).  
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 off-road or on non-surfaced roads. The ACC is designed for use on surfaced roads only.  
Take control of the vehicle immediately if a driver intervention prompt appears on the instrument cluster display  
or if the ACC does not reduce the speed sufficiently.  
Apply the brakes if the vehicle starts rolling unintentionally, e.g. after a driver intervention prompt.  
Be prepared to control the speed yourself at all times.  
215  
Special driving situations  
Overtaking  
If you are indicating left(or right when driving on the left)to overtake, the ACC accelerates the vehicle and reduces  
the gap to the vehicle in front. The system will not exceed the speed you have stored.  
If the ACC has not detected a vehicle in front once you have changed lanes, the ACC will accelerate the vehicle up to  
the selected speed.  
The overtake function is not available in all countries.  
Stop-and-go traffic  
ACC can brake the vehicle to a standstill and hold it stationary. The ACC remains active; the instrument cluster will  
display ACC ready for a few seconds.  
In vehicles which have Travel Assist, you can extend this time by continuing to hold the steering wheel.  
As long as ACC remains active, the vehicle will move off again automatically as soon as the vehicle in front moves off  
(depending on the vehicle equipment level and not available in all countries.)  
Extending or reactivating the period in which the vehicle is ready to pull away:  
Press the  
button.  
Vehicles with Travel Assist: Alternatively, take hold of the steering wheel again.  
Pulling away when the ACC is no longer ready and the vehicle in front is already a long way ahead:  
Press the  
button or briefly depress the accelerator.  
The ACC remains inactive in the following situations:  
The vehicle is stationary for several minutes.  
A vehicle door is opened.  
The ignition is switched off.  
WARNING  
If the message ACC ready appears 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 every time the vehicle starts to pull away and brake the vehicle if necessary.  
Inside Overtaking Prevention System  
216  
Fig. 1 On the display of the instrument cluster: Slower  
vehicle detected in the left-hand lane (illustration).  
If the ACC detects a slower vehicle in the left-hand lane(left-hand traffic: in the right-hand lane), the ACC will brake  
the vehicle gently within the system limits and can therefore prevent a prohibited overtaking manoeuvre. The  
function is active from speeds of approx. 80 km/h (around 50 mph), but is not available in all countries.  
Limits of the ACC  
When not to use the ACC  
For technical reasons, the ACC is not suitable for use in the following situations. Cancel control (→ Adaptive Cruise  
Control (ACC)):  
Driving in heavy rain, snow or heavy spray.  
Driving through road works, tunnels or toll stations.  
Driving on twisting roads, e.g. mountain roads  
Driving off-road  
Driving in multi-storey car parks.  
Driving on roads with embedded metal objects, e.g. railway tracks.  
Driving on roads with loose chippings  
Vehicles without Inside Overtaking Prevention System:On roads with more than one lane, if other vehicles are  
driving more slowly in the overtaking lane.  
WARNING  
Using the ACC in the situations listed above may lead to accidents, severe injuries and violations of the relevant  
statutory regulations.  
Delayed response  
If the radar sensor is exposed to environmental conditions that impair sensor functioning, the system may detect this  
only after a certain delay. For this reason, any restrictions to functions may be displayed only after a delay at the start  
of the journey and when driving (→ Adaptive Cruise Control (ACC)).  
Objects that cannot be detected  
The radar sensor only detects vehicles moving in the same direction as your vehicle. It cannot detect:  
Persons  
217  
Animals  
Crossing or oncoming vehicles  
Other stationary obstacles  
Stationary vehicles  
Fig. 1 Turning vehicle, stationary vehicle  
The ACC can react to stationary vehicles in a limited way up to a speed of around 60 km/h(approx 37 mph). To do so,  
the ACC must detect the stationary vehicle correctly and be able to brake your vehicle comfortably behind it, within  
the system limits. ACC does not perform emergency braking.  
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 react to the stationary vehicle → Fig. 1.  
Cornering  
Fig. 2 Driving through bends.  
The radar sensor always scans the area directly in front of the vehicle. For this reason, the ACC may detect vehicles  
erroneously or may not detect vehicles ahead when driving around tight bends → Fig. 2.  
Vehicles outside of the sensor's range  
Fig. 3 Narrow vehicle.  
218  
Fig. 4 Vehicle changes lane.  
ACC may not react or may react with a delay or with an unwanted response in the following driving situations:  
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. motorbikes→ Fig. 3.  
Vehicles that change into your lane directly in front of your vehicle→ Fig. 4.  
Vehicles with bodies or attachments that project beyond the vehicle.

Press and hold the corresponding button to continuously change the stored speed.  
WARNING  
If you do not maintain the minimum distance to a 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 the ACC is insufficient, you are in danger of colliding  
with the vehicle in front. Rain and winter conditions will also reduce the braking distance.  
The Adaptive Cruise Control may not be able to detect all driving situations correctly.  
Always be prepared to brake the vehicle yourself.  
Depressing the accelerator will override the Adaptive Cruise Control. In this case, the ACC will not brake the  
vehicle automatically.  
Observe any country-specific regulations regarding the minimum distance between vehicles.  
Maintain a larger gap in wet weather, snow or poor visibility.  
221  
Adjusting the way the ACC responds  
You can decide how sporty the response of the ACC should be:  
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 (→ Personalisation).  
Troubleshooting  
ACC not available.  
The indicator lamp lights up yellow.  
The radar sensor is dirty. Clean the radar sensor (→ Vehicle care, exterior).  
The radar sensor's range has been impaired by the weather, e.g. by snow, or residue/layers of cleaning agent.  
Clean the radar sensor (→ Vehicle care, exterior).  
The radar sensor's range is obstructed by add-on parts, trim frame for number plate holders or stickers. Remove  
any obstructions from the area around the radar sensor.  
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).

This is normal and is not a fault.  
222  
Introduction  
The emergency braking system (Front Assist) can detect imminent frontal collisions and issue corresponding  
warnings. The system can also provide assistance for braking and taking avoiding action and can also automatically  
brake the vehicle.  
Front Assist can help to avoid accidents, but is not a substitute for the full concentration of the driver. Front Assist  
functions only within the system limits. The warning times vary depending on the traffic situation and driver  
behaviour.  
Driving with Front Assist  
You can cancel automatic braking interventions by pressing the accelerator or steering.  
You can cancel automatic braking interventions by counter-steering.  
Automatic braking  
Front Assist can decelerate the vehicle to a standstill. The vehicle will not remain stationary. Depress the brake pedal!  
The brake pedal will feel harder during an automatic braking manoeuvre.  
Detection of the traffic situation  
Front Assist detects driving situations by means of a camera located in the upper area of the windscreen and a radar  
sensor in the front of the vehicle.  
Functions  
Front Assist includes the following functions depending on vehicle equipment and country:  
Pedestrian Monitoring.  
Cyclist Monitoring.  
Swerve assist.  
Turning emergency braking.  
The listed functions(where available) 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 risks when  
driving. The driver is always responsible for braking and steering in time.  
If Front Assist issues a warning, brake the vehicle immediately if the traffic allows or avoid the obstacle.  
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.  
Be prepared to take over control of the vehicle yourself at all times and to override automatic braking and  
steering interventions. Front Assist cannot prevent accidents and serious injuries on its own.  
Front Assist can issue unnecessary warnings and carry out unwanted braking or steering interventions in certain  
complex driving situations, e.g. at traffic islands.  
Front Assist can issue unnecessary warnings and carry out unwanted braking or steering interventions when its  
function is impaired, e.g. if the radar sensor is dirty or its position has been changed.  
Without Pedestrian Monitoring, Front Assist does not react to people. Without Cyclist Monitoring, Front Assist  
does not react to cyclists crossing the road. 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 about the functions installed in your vehicle, please contact a qualified workshop before starting  
your journey.  
223  
Make sure you are prepared to take over control of the vehicle at any time.  
Warning levels and braking intervention  
Depending on the vehicle equipment and within the limitations of the system, Front Assist is able to detect the  
following objects:  
Pedestrians, cyclists and vehicles moving relative to your vehicle.  
Crossing pedestrians and cyclists.  
Stationary vehicles.  
If you approach a detected object and maintaining speed would cause a collision without the intervention of the  
driver, Front Assist is able to intervene to provide support. The assistance may include an advance warning, an urgent  
warning and automatic braking.  
Under ideal conditions, this can prevent a collision or help to reduce the effects of the collision.  
Front Assist works in the following speed ranges:

vehicle.  
Advance warning  
The system detects a possible collision and prepares the vehicle for possible emergency braking.  
An acoustic warning sounds and the red warning lamp lights up. Brake or take evasive action!  
224  
Urgent warning  
If the driver fails to respond to the advance warning, the system may jolt the brakes briefly to make the driver aware  
of the increasing risk of a collision. Brake or take evasive action!  
Automatic braking  
If the driver fails to respond to the urgent warning, the vehicle may be braked automatically by applying increasing  
levels of brake force over several stages. The reduced speed may help to minimise the severity of an accident.  
Braking intervention  
If the system detects that the driver is braking insufficiently when there is a risk of collision, the system can increase  
the brake pressure, hence helping to prevent a collision. The braking intervention works only for as long as the brake  
pedal is depressed with force.  
Distance warning  
The system detects safety risks caused by driving too close to the vehicle in front. The indicator lamp lights up.  
Increase the distance.  
Speed range: approx. 65 km/h (40 mph) to 250 km/h (155 mph).  
Front Assist limits  
Front Assist is not available or its functions are restricted immediately after the vehicle is started. During this  
time, the indicator lamp lights up in the display of the instrument cluster.  
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 camera or radar sensor is exposed to environmental conditions that impair functioning, the system may detect  
this only after a certain delay. For this reason, any restrictions to functions may be displayed only after a delay at the  
start of the journey and when driving (→ Autonomous Emergency Braking (Front Assist)).  
Objects that cannot be detected  
Front Assist may not react or may react with a delay or with an unwanted response in the following situations:  
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 and cyclists who are stationary or moving towards the vehicle.  
When pedestrians are not identified as such, e.g. because they are partially or fully hidden.  
Objects or narrow objects such as walls, rails, fences, posts, trees or garage doors.  
225  
Function limitations  
Front Assist may not react or may react with a delay or with an unwanted response in the following situations:  
In tight bends.  
Driving in heavy rain, snow, fog or heavy spray.  
Driving in multi-storey car parks and tunnels.  
Driving on roads with embedded metal objects, e.g. railway tracks.  
Reversing.  
If ESC is regulating or faulty.  
If the radar sensor or camera window is dirty, covered or damaged.  
If several brake lights on the vehicle are defective.  
If there is a fault in several brake lights 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.  
When the sun is low in the sky, in darkness or with glare from oncoming vehicles.  
When driving into and out of tunnels.  
If there is a fault in Front Assist.  
Switching off Front Assist  
Front Assist is not suitable for use in the following situations due to the limitations of the system and must be  
switched off →  
:
If the vehicle is utilised in a capacity beyond usage on public roads, e.g. offroad or racing tracks.  
If the vehicle is being towed or is loaded onto another vehicle.  
If add-on parts cover the radar sensor or camera.  
If the camera or the radar sensor is faulty.  
After external force on the radar sensor, e.g. after a rear-end collision.  
If the windscreen is damaged in the area of the camera window.  
In the event of multiple unwanted interventions.  
WARNING  
Failure to switch off Front Assist in the situations mentioned can cause accidents and serious injuries.  
Pedestrian Monitoring  
Pedestrian and Cyclist Monitoring can help to avoid accidents with pedestrians and cyclists or to mitigate the  
consequences of an accident.  
The system may give a warning when there is a risk of collision, prepare the vehicle for emergency braking, help to  
brake the vehicle or perform an automatic brake intervention. In the event of an advance warning, the red warning  
lamp lights up in the instrument cluster display.  
When Front Assist is switched on and active, Pedestrian Monitoring is also active as an element of Front Assist.  
WARNING  
The intelligent technology of Pedestrian Monitoring cannot overcome the laws of physics, and functions only within  
the limits of the system. Never let the extra convenience afforded by Pedestrian Monitoring tempt you into taking  
any risks when driving. The driver is always responsible for braking in time.  
226  
If Pedestrian Monitoring issues a warning, brake your vehicle immediately depending on the traffic situation or  
avoid the object.  
Pedestrian Monitoring cannot prevent accidents and serious injuries by itself.  
Pedestrian and Cyclist Monitoring can issue unnecessary warnings and carry out unwanted braking interventions  
in complex driving situations, e.g. in a sharply turning main road with an intersection.  
Pedestrian and Cyclist 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 if the camera window is dirty.  
Make sure you are prepared to take over control of the vehicle at any time.  
Swerve support  
The swerve assist function can help to steer the vehicle around an obstacle in critical driving situations.  
If you steer to avoid an obstacle after an urgent warning, swerve assist can help you. Swerve support brakes  
individual wheels and corrects your steering wheel angle while you steer the vehicle.  
Speed range  
Swerve assist is available in a speed range from around 30 km/h(around 20 mph) up to 150 km/h (around 90 mph).  
Limits  
Swerve support does not react to crossing objects and animals. Always also observe the fundamental limits of Front  
Assist (→ Autonomous Emergency Braking (Front Assist)).  
227  
Oncoming vehicle braking when turning  
The oncoming vehicle braking when turning function can prevent the vehicle from colliding with an oncoming  
vehicle during a turn.  
If there is a risk of the vehicle colliding with an oncoming vehicle in the adjacent lane when turning, the oncoming  
vehicle braking when turning function can brake your vehicle. The vehicle can then remain in its own lane as a result.  
Speed range  
The oncoming vehicle braking when turning function is available at speeds of up to approximately 15 km/h(around  
9 mph).  
Limits  
The oncoming vehicle braking when turning function is available only if you have activated the turn signal and turned  
the steering wheel to start the turning manoeuvre. However, after changing from right-hand driving to left-hand  
driving or vice versa, the oncoming vehicle braking when turning function is only available after a certain time  
(30 minutes or more).  
The oncoming vehicle braking when turning function does not react to persons, animals, crossing vehicles or objects  
that are not detected as a vehicle. Always also observe the fundamental limits of Front Assist (→ Autonomous  
Emergency Braking (Front Assist)).  
228  
Operating Front Assist  
Front Assist and all the included functions(country-dependent) are automatically switched on when you switch on  
the ignition.  
However, Front Assist is not available or only available to a limited extent as long as the indicator lamp is lit.  
Volkswagen Commercial Vehicles recommends that Front Assist and all the included functions(country-dependent)  
are switched on at all times. Exceptions (→ Autonomous Emergency Braking (Front Assist)).

Introduction  
The lane keeping system(Lane Assist) helps the driver stay in lane. The function is not designed to keep the vehicle  
in lane automatically, nor is it suited to this purpose.  
Using a camera in the windscreen, the lane keeping system detects lane markings on the road. If your vehicle moves  
too close to a recognised road lane marking, the system will warn the driver with a corrective steering intervention.  
The corrective steering intervention can be overridden by the driver at any time.  
System limits  
Use the lane keeping system only on motorways and good main roads.  
The system is not available under the following conditions(passive system status):  
The vehicle speed is under approximately 55 km/h(around 30 mph).  
The lane keeping system has not detected a road lane marking.  
On tight bends  
Temporarily if the driving style is very sporty.  
WARNING  
The intelligent technology used in the lane keeping system cannot overcome the laws of physics, and functions only  
within the limits of the system. Always take care when using the lane departure warning system otherwise you  
could cause accidents or injuries. The system is not a substitute for the driver's full concentration and steering  
manoeuvres.  
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. The driver is always  
responsible for staying in lane.  
The lane keeping system cannot recognise all lane markings. In certain circumstances, the lane keeping system  
may detect poor road surfaces, road structures or objects incorrectly as lane markings. Immediately override any  
undesired intervention by the system.  
Observe the information on the instrument cluster display and respond according to the prompts, if permitted by  
the traffic situation.  
In the following situations, the lane keeping system may intervene in an unwanted manner or fail to intervene as  
designed. This means that it is crucial that the driver is attentive in these situations. It may be necessary to switch  
off the lane keeping system temporarily:  
Very sporty driving.  
In poor weather conditions and when driving on poor roads.  
Driving through road works.  
Crests and dips in the road.  
Always observe the area around the vehicle with care and watch the road ahead while driving.  
If the camera's field of view is dirty, covered or damaged, the function of the lane departure warning system may  
be impaired.  
231  
Driving with the lane keeping system  
Switching on and off  
Depending on country, the lane keeping system is always switched on when the ignition is switched on. You can also  
switch the lane keeping system on and off in the Assist systems menu on the Infotainment system and instrument  
cluster and view the current system status there.  
If there is a system fault, the lane keeping system can deactivate itself  
automatically.  
Speed range  
When road lane markings can be detected, the lane keeping system is ready to intervene at speeds above around  
60 km/h (around 35 mph) (system status active).

System is active and ready to perform control intervention.  
System controls (corrective steering intervention).  
If no warning lamp lights up, the system is not ready to intervene(passive system status) or is switched off.  
When the indicator is on, the system temporarily switches to passive mode to allow manual lane changes.  
The system also switches to the passive state temporarily if the driver applies a heavy steering input to override the  
corrective steering intervention.  
232  
If the comfort drive function(Travel Assist) is actively performing a control operation, there is no steering  
intervention and the lane keeping system is not displayed.  
Driver intervention prompt  
If there is no steering activity, the system prompts you to drive in the middle of the lane by means of acoustic  
warnings and a display on the instrument cluster.  
The system switches to the passive state if you do not react. Depending on the equipment, Emergency Assist will be  
activated providing it is switched on in the Infotainment system.  
Independently of steering activity, you are also prompted to drive in the middle of the lane by means of a display on  
the instrument cluster and acoustic warnings if the corrective steering intervention takes place for an extended time.  
Steering wheel vibration  
The following situations can lead to vibration of the steering wheel:  
The system can no longer detect a lane during a major steering intervention.  
You can also select theVibration or Steering wheel vibration option in the Assist systems menu on the Infotainment  
system. In this case, the steering wheel will vibrate if the vehicle drives across a detected road lane marking when the  
lane keeping system is active.

233  
Introduction  
Travel Assist combines Adaptive Cruise Control(ACC) with adaptive lane guidance. Within the system limits, this  
enables the driver to keep the vehicle at a preselected distance from the vehicle in front and stay in a predefined  
position within the lane.  
Travel Assist uses the same sensors as the Adaptive Cruise Control(ACC) and the lane keeping system (Lane Assist).  
Please, therefore, read the information on ACC and Lane Assist carefully and observe the system limits and warnings  
listed there.  
Speed range  
Travel Assist regulates at speeds between around 30 km/h(approximately 20 mph) and around 210 km/h  
(approximately 130 mph). Adaptive lane guidance can be used at speeds between 0 km/h (0 mph) and around  
250 km/h (approximately 155 mph). This speed range may differ in certain markets.  
Driving with Travel Assist  
Travel Assist controls the accelerator, brake and steering automatically. Within the system limits, Travel Assist can  
decelerate the vehicle to a standstill behind a vehicle that is stopping. It can also start driving again by itself.  
You can override Travel Assist regulation at any time.  
Does the vehicle have Travel Assist?  
The vehicle is fitted with Travel Assist if the multifunction steering wheel has a button.

Driver intervention prompt  
If you take your hands off the steering wheel, the system prompts you within a few seconds to take over active  
steering by way of acoustic warnings and a display on the instrument cluster.  
Travel Assist will be deactivated if you do not respond to the prompt.  
Alternatively, Emergency Assist will be activated(with some equipment levels).  
WARNING  
The intelligent technology used in Travel Assist cannot overcome the physical limits specified, and functions only  
within the limits of the system. Careless or unintentional use of Travel Assist can cause accidents and serious  
injuries. The system is not a substitute for the full concentration of the driver.  
Observe the system limits and information on Adaptive Cruise Control(ACC) and the lane keeping system (Lane  
Assist).  
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.  
Never use Travel Assist 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 Travel Assist offroad or on unsurfaced roads. Travel Assist is designed for use on surfaced roads only.  
Travel Assist does not react to persons, animals or vehicles crossing or approaching in the same lane.  
Brake immediately if a brake request is displayed on the instrument cluster display or if the speed reduction by  
Travel Assist is not sufficient.  
Brake if the vehicle starts rolling unintentionally, e.g. after a brake request.  
Your hands should always be on the steering wheel so that you are ready to steer at any time. The driver is always  
responsible for staying in lane.  
Take control of the vehicle immediately if a driver intervention prompt appears on the instrument cluster display.  
Be prepared to control the speed yourself at all times.

236  
Semi-automatic vehicle control in a medical emergency (Emergency Assist)  
Emergency Assist can detect a lack of activity on the part of the driver and keep the vehicle in the lane  
automatically, or brake the vehicle to a standstill if required. The system can therefore actively contribute to  
preventing or reducing the consequences of an accident.  
Emergency Assist uses the same sensors as the Adaptive Cruise Control(ACC) and the lane keeping system (Lane  
Assist). Please, therefore, read the information on ACC and Lane Assist carefully and observe the system limits and  
warnings listed there.  
Driver intervention prompt  
If the driver is inactive, Emergency Assist emits acoustic warnings and applies a braking jolt to prompt the driver to  
take control of the vehicle. A message also appears on the instrument cluster display and the volume of the  
Infotainment system is reduced.  
System intervention  
The system can brake the vehicle and keep it in lane if the driver does not react. The following indicator lamp lights  
up in the instrument cluster display:  
or  
System controls (corrective steering intervention).  
You can override control at any time by steering, accelerating strongly or braking.  
Other road users will be warned as follows when Emergency Assist is actively performing control interventions:  
The hazard warning lights will be switched on after a short time.  
The vehicle horn will sound(depending on speed).  
The following will happen as soon as the vehicle is stationary:  
The doors will be unlocked.  
The interior lighting will be switched on.

Fault or malfunction. Switch off and restart the engine.  
If the problem persists, switch off Emergency Assist and go to a qualified workshop.  
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.  
Emergency Assist cannot always prevent accidents and serious injuries on its own.  
If the radar sensor or the front camera are covered or have been displaced, Emergency Assist may carry out  
unwanted braking or steering interventions.  
Emergency Assist does not react to persons, animals or vehicles crossing or approaching in the same lane.  
WARNING  
If Emergency Assist is triggered unexpectedly, it can result in accidents and serious injuries.  
If the vehicle behaves differently to expected, cancel the intervention of Emergency Assist by accelerating  
strongly, braking or steering.  
Do not use Travel Assist and Lane Assist. Go to a qualified workshop and have the system checked.  
Introduction  
The lane change assist system(Side Assist) provides assistance when checking for traffic behind the vehicle.  
Radar sensors monitor the area behind the vehicle. The system measures the distance and speed difference in  
relation to other vehicles and informs the driver by means of visual signals in the exterior mirrors.  
System limits  
Use the lane change system only on paved roads.  
The lane change system may interpret the traffic situation incorrectly in the following driving situations, for example:  
On tight bends  
When driving in between two lanes  
When road lanes are not the same width  
At the brow of a hill  
In poor weather conditions  
Where there are special roadside structures, e.g. high or offset crash barriers.  
WARNING  
The intelligent technology used in the lane change system cannot overcome the laws of physics, and functions only  
within the limits of the system. Do not let the increased convenience of the lane change system tempt you into  
taking any safety risks. Always take care when using the lane change assist system as you could otherwise cause  
accidents or 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 must always remain on the steering wheel so that you can steer at any time.  
Observe the signals on the exterior mirror housing and in the instrument cluster display, and respond to the  
prompts.  
Always pay close attention to the area around your vehicle.  
Never use the lane change assist system if the radar sensors are dirty, covered or damaged. These circumstances  
can impair the proper functioning of the system.  
It may be hard to see the display in the exterior mirror in direct sunlight.  
238  
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).  
The radar sensors calibrate themselves once during the first kilometres after vehicle delivery and after sensor  
repairs. The sensor range may be restricted during the calibration phase.  
Driving with the lane change system  
Fig. 1 In the exterior mirror housing: Lane change system  
display (illustration).  
Switching on and off  
1. Press the  
button.  
2. Switch the lane change system on and off in the Assist systems menu in the instrument cluster.  
Depending on the equipment, you can also switch the lane change system on and off in the Assist systems menu in  
the Infotainment system. The yellow indicator lamp in the exterior mirror housing lights up once briefly when the  
1
lane change system is switched on → Fig. 1  
.
This most recent system setting is retained even after the ignition has been switched off and on.  
How the system works  
When switched on, the lane change system is active from speeds of around 15 km/h(around 9 mph). The lane  
change system is deactivated at speeds below 10 km/h (around 6 mph).  
The yellow indicator lamp lights up in the housing of the respective exterior mirror in the following driving situations  
:
If the vehicle is being overtaken.  
When overtaking another vehicle with a speed difference of up to approximately 15 km/h(around 9 mph). No  
display will be shown if the takeover manoeuvre is much faster.  
The yellow indicator lamp flashes if the system detects a potentially critical situation when you activate the turn  
signal in the direction of the detected vehicle.  
The quicker the vehicle approaches, the earlier it causes the display on the exterior mirror to light up.  
Lane change system “Side Assist Plus”  
If the vehicle is equipped with a lane keeping system(Lane Assist) and the system is switched on, it performs a  
239  
corrective steering intervention to warn you when changing lanes during a potentially critical situation (information  
level / warning level). The steering intervention also occurs when you operate the turn signal for the corresponding  
direction. If you override the steering intervention, the steering wheel vibrates to give an additional warning. For this,  
steering wheel vibration must be activated in the Assist systems menu in the Infotainment system.  
Automatic deactivation  
The lane change system will switch off automatically if the radar sensors are permanently covered. This can, for  
example, be caused by a layer of ice or snow in front of the radar sensor.  
A corresponding text notification is shown on the instrument cluster display.  
If the lane change system sensor has been automatically deactivated, the system cannot be activated until the  
ignition has been switched off and back on again.  
The lane change system is switched off automatically when the factory-fitted towing bracket is electrically  
connected to a trailer or similar. The lane change system is automatically switched on again when the trailer is  
unhitched from the vehicle. The lane change system must be switched off manually for non-factory-fitted towing  
brackets.  
Brightness  
The brightness of the visual display will automatically adapt to the light levels.  
Depending on the equipment, you can adjust the basic brightness of the display in the Assist systems menu in the  
Infotainment system. The lane change system is not active during the setting procedure.  
Troubleshooting  
Fault in lane change system.
