System limits
r-('n First read and observe the Introductory L-J,:.U Information and safety warnings & on page 307.
The area monitoring system (Front Assist) has physical and system-related limits. The driver may therefore feel that, in certain circumstances, some Front Assist reactions occur unexpectedly or with a delay. You should therefore always be prepared to take full control of the vehicle if necessary.
The following conditions can prevent Front Assist from reacting, or cause a delay in its reaction:
• In tight bends.
• If the accelerator is fully depressed.
• If Front Assist is switched off or there is a fault.
• If TCS or ESC is switched off manually.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the radar sensor is dirty or covered.
• If the vehicle is reversing.
• Under hard acceleration.
• In snow or heavy rain.
• In case of narrow vehicles, e.g. motorbikes.
• If vehicles are travelling slightly to the left or right of your vehicle.
• If vehicles are crossing in front of your vehicle.
• If there is oncoming traffic.
• In uncertain traffic situations.
• 1/Vhen loads or attachment parts on other vehi-cles protrude to the side, rear or above the normal dimensions of the vehicle. Lane change assist system (Side Assist)

The lane change assist system (Side As-
sist) provides assistance when checking
for traffic behind the vehicle.
The lane change assist system cannot be switched on if the factory-fitted towing bracket is electrically connected to the trailer. The lane change assist system must be switched off manually for non-fac-tory-fitted towing brackets.
The lane change assist system has been designed for use on surfaced roads only.

A WARNING
The Intelligent technology of the lane change assist system (Side Assist) cannot change the laws of physics or the system-related ve-hicle limitations. Always take care when us-Ing 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 should always be on the steer-Ing wheel so that you can steer at any time.
• Pay attention to the visual displays in the exterior mirror housing and in the Instrument cluster display, and respond to the com-mands.
• The lane change assist system may react to special roadside structures, e.g. high or offset crash barriers. This can lead to error warnings. ,..

A WARNING (Continued)
• Never use the lane change assist system on unsurfaced roads. The lane change assist system has been designed exclusively for use on surfaced roads.
• Always pay close attention to what Is hap-pening around the vehicle.
• Never use the lane change assist system, If the radar sensors are dirty, covered or dam-aged. These circumstances can Impair the proper functioning of the system.
• lt may be hard to see the display In the ex-terior mirror In direct sunlight.
• The sensors In the rear bumper can be shif-ted or damaged through Impacts, e.g. when parking. As a result the system may switch it-self off or at least be impaired.

Lights up or Possible cause flashes
The lane change assist system is cur-rently not available.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will go out after a few seconds.
• The system sensors In the bumper must be kept clean and free of ice and snow and not be covered up otherwise the system will not work properly.
m Only Volkswagen-approved vehicle paints L!..J may be used on the rear bumper. Other vehi-cle paints could limit or even distort the function of the lane change assist system.
m If the lane change assist system does not L!..J function as described in this chapter, or after a collision with another vehicle, do not use the sys-tem. Go to a qualified workshop.
m Go to a qualified workshop and have the sys-L!..J tern checked ifthere is a fault in the system or after an accident. A WARNING
Failure to observe illuminated warning lamps and text messages can lead to your vehicle breaking down in traffic, and can cause acci-dent and serious Injury.
• Never ignore any illuminated warning lamps or text messages.
• Stop the vehicle as soon as possible and when safe to do so.
Failure to observe illuminated Indicator lamps and text messages can lead to your vehicle be-Ing damaged. Driver assist systems 313

Operation

r-f"n First read and observe the introductory L-W! information and safety warnings & on page 312.
Visual display in the exterior Situation mirror housing
The lane change assist system uses radar sensors to monitor the area behind the vehicle. The system then measures the distance and the difference in speed to other vehicles. The lane change assist system is activated at speeds over approximately 10 km/h (6 m ph) and deactivated at speeds under 5 km/h (3 mph). The driver receives infonmation via the visual display in the exterior mirror housing.
Visual display in the exterior mirror housing
The visual displays 248 in the exterior mirror housing notify the driver of following traffic on ei-ther side of the vehicle whenever a traffic situation is classified as critical when the driver intends to change lanes.
Tinted side windows or retrofitted tinting foils can negatively affect or distort the visual displays in the exterior mirror.

Radar sensors
The radar sensors are on the left and right behind the rear bumper and are not visible from outside. They monitor an area of approximately 70 metres behind the vehicle and the blind spots to the right and left of the vehicle. The monitored area to the side of the vehicle is approximately one lane wide.
The width of the lane is not detected in individual cases. but is predefined in the system. For this rea-son. incorrect displays could be shown when driv-
314 I While driving
ing in narrow lanes or when driving in the middle of 2 lanes. In the same way, vehicles travelling in the lane next to the one you wish to change to could be detected, as could solid objects such as safety barriers. and trigger an incorrect warning.

The following driving situations trigger a light in the exterior mirror 249 [ID (arrow) or 250 [ID (arrow):
• When another vehicle is overtaking your vehi-cle 249
• When overtaking another vehicle 250 with a speed difference of up to approximately 15 km/h (9 m ph). No display will be shown if the take-over manoeuvre is much faster.
The display in the exterior mirror will be shown ear-lier the faster you are nearing another vehicle as the lane change assist system calculates the
speed difference to other vehicles. For this reason, the display could be activated at different times de-spite your vehicle being at the same distance from other vehicles.
Physical and system-specific limits
The lane change assist system might, for example, interpret the traffic situation incorrectly in certain driving situations. In the following situations, for ex-ample:
• In tight bends.
• When road lanes are of varying width.
• At the brow of a hill.
• In poor weather conditions.
• Where there are special roadside structures, e.g. high or offset crash barriers. <1

The Driver Alert System determines the driving be-haviour at the beginning of a journey and uses it to evaluate the tiredness of the driver. This is com-pared to the behaviour of the driver while actually driving. If the system detects that the driver may be tired, an acoustic warning signal ("gong") will sound and an explanatory message or symbol (BREAK or =>Fig. 251) will appear in the instrument cluster display. The message on the instrument cluster display appears for about five seconds and may be repeated once. The last displayed mes-sage is saved by the system.
The message in the instrument cluster display can be switched off by pressing the (OK/RESIT I button on the wiper lever or the@ button on the multifunc-

A WARNING (Continued)
• The system cannot always detect the driv-er's level of alertness. Observe the Informa-tion In the section "Function limitations" =>page 316.
• In certain situations, the system may wrongly Interpret Intentional driving manoeu-vres as a lack of alertness from the driver.
• No urgent warning will be given In the event of the phenomenon known as "micro-sleep".
• Follow the Information on the Instrument cluster display and respond according to the commands.
