or animals, or to vehicles that cross or approach  
from the opposite direction in the same lane.  
— In case of adverse weather conditions.  
— In case of special constructions on the margins, e.g. g., high  
or misaligned guardrails.  
If the emergency assistant (Emergency Assist) intervenes  
inappropriately, accidents and serious injuries can occur.  
The intelligent technology of Lane Change Assist cannot  
overcome the limits imposed by the laws of physics and only  
works within the limits of the system. Never let the increased  
comfort provided by Lane Change Assist induce you to take any  
risk that compromises safety. If lane change assist is used  
carelessly or inadvertently, accidents and serious injuries can  
result. The system cannot replace the attention of the driver.  
· If the emergency assist does not work correctly, if  
necessary, interrupt it by moving the steering  
wheel or pressing the brake pedal and deactivate  
the lane departure warning assistant (Lane  
Assist) so that the emergency assist is also  
deactivated ÿ p. 176.  
· Do not use the driving assistant (Travel As sist)  
or the lane departure warning assistant (Lane  
Assist), go to a specialized workshop and have  
the system checked. Volkswagen recommends  
going to a Volkswagen dealer for this.  
· Always adapt the speed and the safety distance  
with respect to the preceding vehicle depending  
on the visibility, weather, road and traffic  
· Always keep your hands on the wheel to be ready  
to intervene in the steering at any time.

· Always carefully observe the surroundings of  
the vehicle.  
Lane Change Assist assists the driver by recording the  
traffic situation behind the vehicle.  
· Never use Lane Change Assist if the radar sensors  
are dirty, covered or damaged. The operation of  
the system can be affected in these cases.  
Radar sensors monitor the area behind the vehicle. The system  
measures the distance and the difference in speed in relation to  
other vehicles and informs the driver through optical signals in the  
exterior mirrors.  
· In case of direct sunlight, the visual display of  
the exterior mirrors may be limited.  
Some settings can be saved to user accounts in the  
personalization function.  
System limitations

Lane Change Assist cannot correctly interpret the traffic situation  
in the following driving situations, among others:  
kilometers after vehicle delivery and after a repair to the  
radar sensors. During the calibration phase, the range of the  
sensors may be limited.

— In case of driving between two lanes.  
— In case of lanes of different width.

If the vehicle is equipped with Lane Departure Warning Assist and  
is switched on, the driver is warned when changing lanes in the  
event of a possible critical situation (information level, warning  
level) by correcting the direction. This also happens when the  
indicator is connected for the corresponding direction. If the driver  
cancels this intervention in the direction, the system warns, in  
addition, with a vibration of the steering wheel. To do this, the  
steering wheel vibration must be activated in the infotainment  
system, in the vehicle settings menu.

— Radar sensors are covered with water.  
— The vehicle is damaged in the area of the radar sensors,  
e.g. e.g., due to some blow to the side  
— The detection area of the radar sensors is blocked by an

— There have been paint changes in the area of the radar  
sensors or structural changes, e.g. e.g. at the front of the  
vehicle or on the running gear.
