Lane keeping system (Lane Assist)
Introduction
This chapter contains information on the followingsubjects:
Driving with the lane keeping system
Troubleshooting
The lane keeping system (Lane Assist) helps the driver stay in lane.
Using a camera in the windscreen, the lane departure warning system detects lane markings on the
road. If your vehicle moves too close to a recognised 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.
Adaptive lane guidance (depending on vehicle equipment)
The adaptive lane guidance system detects the preferred position in a lane and keeps the vehicle in
this position.
Adaptive lane guidance is switched on and off in the Driver assistance menu in the Infotainment
system Vehicle settings menu
System limits
Use the lane keeping system only on motorways and good main roads.
The system is not active under the following conditions:
The lane keeping system has not detected any lane markings.
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 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. The driver is
always responsible for staying in lane.
The lane keeping system cannot recognise all lane markings. Poor road surfaces, road structures or
objects could be recognised incorrectly as lane markings by the lane keeping system. The lane
keeping system should be switched off immediately in these situations.
Follow the information on the instrument cluster display and respond according to the commands.
If the camera's field of view is dirty, covered or damaged, the function of the lane keeping system
may be impaired.
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

Lane markings detected. System is regulating. Adaptive lane guidance active.
Switch off the lane keeping system in the following situations:
Very sporty driving.
In poor weather conditions and when driving on poor roads.
In roadworks and before crests in the road.
Driver intervention prompt
In the absence of any steering input, the system prompts the driver with acoustic warnings and a
display on the instrument cluster display to take over active steering.
If the driver does not respond, the system will give another warning by initiating a quick jolt of the
brake before switching to passive mode or activating Emergency Assist (with some equipment
levels).
Steering wheel vibration
The following situations can lead to vibration of the steering wheel:
If the corrective steering intervention is not sufficient to keep the vehicle in its lane.
If the system can no longer detect a lane during a significant steering intervention.
If there is a system fault, the lane keeping system can deactivate itself automatically.
Troubleshooting
First read and observe the introductoryinformation and safety warnings
No camera visibility, error message, system switches itself off
Clean the windscreen Caring for and cleaning the vehicle exterior
Check whether any damage is visible on the windscreen in the camera's field of view.
The system is not responding as expected
Regularly clean the camera's field of view, and keep it free from snow and ice.
Do not cover the camera's field of view.
Check the area of the windscreen that is in the camera's field of view for damage.
Do not fit any objects to the steering wheel.
Traffic Jam Assist
Traffic Jam Assist helps the driver to keep in lane, and also provides assistance when following other
vehicles in congestion or slow-moving traffic.
Driving through road works.
In urban areas.
WARNING
The intelligent technology of Traffic Jam Assist cannot overcome the laws of physics, and functions
only within the limits of the system. Always take care when using Traffic Jam Assist 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.
Do not use Traffic Jam Assist in urban traffic.
Do not use Traffic Jam Assist in poor visibility, on steep or winding roads, or on slippery road
surfaces e.g. on snow, ice, wet roads, loose chippings or flooded roads.
Never use Traffic Jam Assist offroad or on unsurfaced roads. Traffic Jam Assist is designed solely for
use on surfaced roads.
Traffic Jam Assist does not react to persons, animals or vehicles crossing or approaching in the same
lane.
If the speed reduction achieved by Traffic Jam Assist is insufficient, brake the vehicle immediately by
depressing the foot brake.
If the vehicle starts to roll unintentionally after the driver has been prompted to take control of the
vehicle, brake the vehicle immediately using the foot brake.
If a driver intervention prompt appears on the instrument cluster display, take control of the vehicle
immediately.
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 driver must be prepared to take control of the vehicle (by accelerating or braking) at all times.
If Traffic Jam Assist does not function as described in this chapter, do not use the system and go to a
qualified workshop.
If there is a fault in the system, visit a qualified workshop and have the system checked.
Semi-automatic vehicle control in a medical emergency (Emergency Assist)
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
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.
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
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
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
Blind Spot Monitor is not working
The indicator lamp lights up yellow.
Go to a qualified workshop.
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.
