2021 AUDI TT key battery

8S1012721BE
Assist systems


— If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
— In poor weather conditions such as heavy
rain, snow or heavy mist.
— On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor

range.

() Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or authorized Audi
Service Facility check their function.
@ Tips
— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect:
—The system complies with United States FCC
regulations and ISED regulations
=> page 261.
Sic Rema
Applies to: vehicles with Audi side assist

MENU > Select in the Infotainment system: but-
ton > Vehicle > left control button >Driver as-
sistance > Audi side assist

If the system is activated, the displays in the ex-
terior mirrors will turn on briefly when the igni-
tion is switched on.
Adjusting the display brightness
Applies to: vehicles with Audi side assist
The display brightness can be adjusted in the In-
fotainment system.

MENU > Select in the Infotainment system: but-
ton > Vehicle > left control button >Driver as-
sistance > Audi side assist

The display brightness adjusts automatically to
the brightness of the surroundings, both in the
information and in the warning stage. In very
dark or very bright surroundings, the automatic
adjustment will set the display to the minimum
or maximum level. In such cases, you may notice
no change when adjusting the brightness, or the
change may only be noticeable once the sur-
roundings change.
Adjust the brightness to a level where the display
in the information stage will not disrupt your
view
ahead. If you change the brightness, the dis-
play in the exterior mirror will briefly show the
brightness level in the information stage. The
brightness of the warning stage is linked to the
brightness in the information stage and is adjust-
ed along with the information stage.
(i) Tips
— Side assist is not active while you are mak-
ing the adjustment.
— Your settings are automatically stored and
assigned to the remote control key being
used.
