Audi side assist lane-change system
The side assist system helps the driver to monitor dead corners and the situation on the road behind the vehicle. It warns, within the limits of the system, of vehicles approaching or moving in the same lane in the -1- zone: if a lane change is deemed critical, the -2- indicator in the exterior rear-view mirror is illuminated
The indication on the left exterior mirror helps when changing lanes to the left, and the indication on the right exterior mirror helps when changing lanes to the right.
As long as the turn signal light is not on, the side assist system informs the driver of recognized vehicles that are classified as critical. The indicator light on the corresponding mirror illuminates faintly.
The brightness of the display in the information stage is intentionally low so as not to disturb the driver when looking ahead.
If the driver has switched on the turn signal light, side assist warns him of detected vehicles that are regarded as critical. The indicator on the corresponding mirror lights up brightly. In this case it is necessary to check the driving situation by looking in the outside rear view mirror and glancing over your shoulder.
The side assist system starts to work at speeds of 30 km/h or more.
-A- approaching cars.
In certain cases, a vehicle is classified as critical to change lanes, even if it is farther away. The faster the car approaches, the earlier the indication on the outside mirror lights up.
-B- Cars coming in the flow
Cars coming in the flow are displayed in the exterior rearview mirror if they are classified as critical. All cars recognized by “side assist” are displayed in the blind spot at the latest.
-C- cars lagging behind
If slow overtaking of a detected vehicle (speed difference of less than 15 km/h) is performed, the indicator on the exterior mirror lights up when the vehicle is in the blind spot.
If you overtake a detected vehicle quickly (speed difference of more than 15 km/h), the indicator does not illuminate.
The radar sensors are designed in such a way that they cover the left and right adjacent lanes when the lane width is normal. In some situations, the indicator light on the exterior rearview mirror may illuminate even though no vehicle is in the critical zone for lane change, for example: For example:
When lanes are narrow, or if your vehicle is traveling almost to the edge of the lane. In this case, the next lane may be covered and a vehicle that is not in the adjacent lane is registered.
When the vehicle is driving in a curve. The side assist system may respond to a vehicle traveling in a lane one across from yours.
If the side assist system reacts to other objects (such as high or offset bumpers.
In bad weather. The side asist system is limited in functionality.
The radar sensors cannot be covered by stickers, deposits, bike holder, or similar items, as they interfere with the functionality of the system. The side assist system should not be used when driving with a trailer. For cleaning instructions, refer to the information on cleaning. Link.
Constantly monitor the situation on and around the car. The side assist system does not exempt the driver from the need for caution. Responsibility for lane changes and similar manoeuvres always rests with the driver.
In some situations the system may not work or may be limited.
With very fast approaching or lagging vehicles. The indicator may not illuminate in time.
In bad weather, such as: heavy rain, snow or heavy splashing.
In very wide lanes, on steep curves or when driving on elevated roads. Cars in the neighboring lane may not be registered because they are out of range of the system.
Bumps or damage to bumpers, fender arches and underbody can dislodge sensors. This may adversely affect the operation of the system. Have their functionality checked by a specialist company.
If the driver’s and front passenger’s door windows are tinted with film, the display in the exterior rearview mirror may be impaired.
To activate/deactivate the system, press the CAUTION key! When the side assist system is on, the LED in the button lights up.
You can adjust the brightness of the display in the Infotainment system*.
Select: CAR function key > System control button or Vehicle systems > Driver assistance > Audi side assist.
The brightness of the display automatically adjusts to the outside light in both information and warning mode. If the outside light is too dark or too bright, the degree of indication reaches an upper or lower limit due to automatic adaptation. In such cases it may be that no change is visible when adjusting or only visible after a change in the ambient conditions.
Adjust the brightness so that the indicator does not interfere with looking ahead during the information phase. If the driver changes the brightness, the indicator in the exterior mirror briefly shows the brightness for the information stage. The brightness of the warning stage is linked to the information stage brightness and is automatically set in conjunction with the latter.
The side assist system is inactive during adjustment.
The settings are automatically saved in memory and correspond to the radio key used.
If the side assist system is switched off on its own, the control lamp in the button goes out and an instruction for the driver appears in the instrument cluster display:
Audi side assist not available: sensors blocked
The view of the radar sensors is impaired. The area in front of the sensors must not be covered with a bike holder, stickers, dirt, etc. If necessary, clean the area in front of the sensors
Audi side assist: currently not available
The side assist may not be activated temporarily due to malfunctions (e.g. low battery charge).
Audi side assist: system fault
The system can no longer reliably detect vehicles and is switched off. Sensors are misaligned or damaged. Have the system checked by a workshop at the earliest opportunity.
Audi side assist not available when towing
If vehicles with factory-fitted trailer coupling have an electrical connection to the trailer’s power outlet, side assist is automatically disengaged. If a coupling ball bar is additionally installed, it is not possible to ensure that the system is switched off.
The side assist system must not be used when driving with a trailer.
