Audi adaptive cruise
control
Description
A ppl ie s to: ve hicles w ith Audi adaptive cruise co ntro l
Fig. 107 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by both regulating the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system . If the sys­
tem detects a vehicle driving ahead, the adaptive
cru ise control can brake and acce lerate your vehi­
cle. This increases driving comfort dur ing long
tr ips on highways and in stop-and -go traff ic (au ­
tomatic transmission*).
What can adaptive cruise control do?
The adaptive cruise contro l system uses video, ra­
dar, ultrasound and navigation data. Veh icles
108
driving ahead can be recognized up to 650 feet
(200 m) away.
P red ictive functions offer the driver additional
comfort and contribute to the reduction in fue l
consumption and CO2 emiss ions
r:!> page 115.
On open roads with no traffic , it functions like a
c ruise control system. The stored speed is main­
tained . When approaching a vehicle driving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle dr iving
ahead, adaptive cruise control accelerates up to
the stored speed.
App lies to: vehicles wit h auto matic transmissions
In stop-and-go traffic, adaptive cruise control can
brake until the veh icle is stationary and then can
also start driving again automat ically under cer­
ta in cond itions
r:!> page 112 .
In traffic jams or s top-and-go traffic, traffic jam
ass ist can ass ist the driver
r:!> page 116.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "contro l speed"
r:!> page 110, Switching on/off.
When dr iving, you can stop cruise control
c:>page 113 or change the speed c::;,page 112 at
any time .
You can also set the distance to the vehicle driv­ i ng ahead and set the driving mode of the adap­
tive cru ise cont rol
