Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lat ing vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system.
If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle. This helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 90.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

Fig. 85 Front of th e veh icle: senso rs and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera
c:::> fig. 85
must neve r be cove red by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
c:::> page 209. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> page 86, fig. 88 .
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of veh icles are hard to detect;
for examp le motorcycles, veh icles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
-When driving through curves

& WARNING
A lways pay attention to traffic when adap ­
tive cruise contro l is switched on and brak­
ing g uard is active. As the driver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled o r disabled vehicle.

(D Note
- Make sure there is eno ugh clearance
above and below the veh icle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi ­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change d uring transpor t. The vehicle
may not be sec ured s uff icient ly if this
happens.

The Automatic Shift Lock only functions when
the vehicle is stationary or at speeds below
1 mph (2 km/h).
At speeds above about 1 mph (2 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the N position.
A time delay element prevents the se lector
l eve r from locking when it is moved thro ugh
the N position (going from R to 0/5). The lock­
ing e lement will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
prox imately 2 second, without the brake ped­
al being pressed.

110 Automatic Tran sm iss ion
multitronic transmission : Your vehicle is
equipped with
hill hold assist allowing you to
start while on an incline. The system is acti­
vated when the brake pedal is pressed down
and held
f o r a few s econds . The brake pres­
sure will hold for
a moment after the brake
pedal loosens to prevent the veh icle from roll­
ing backwards whi le starting up .
A WARNING
- The veh icle can also roll when the engine
is stopped.
- Unintended veh icle movement can cause
serious injury .
- Never leave your vehicle with the eng ine
running wh ile in gea r. If you must leave
yo ur vehicle when the engine is running,
act ivate the park ing brake and move the
selector lever to P .
- Power is st ill transmitted to the whee ls
when the engine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever pos ition
wh ile the vehicle is stat io nary and the
engine is running .
- Never shift into R or P wh ile driving .
- Before driv ing down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when dr iving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces b raking performance, inc reases
braking distance or causes comp lete fail­
ure of the brake system.
- T o prevent the veh icle from rolling back
when stoppi ng on incl ines, always hold it
in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipping clutch. The clutch opens auto ­
matically when it becomes too hot from the overload. An indicato
r lamp
ml illu­
minates and a driver message appears
¢ page 112 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving posit io n engaged when
checking under the hood . Make sure the
selector lever has securely engaged and is locked in P w it h the park ing brake set
¢ page 222 . Otherwise, any increase in
eng ine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
(D Note
-S tronic- and tiptronic transmission :
When stopping on an incl ine , do not try
t o hold the vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
peda l to prevent the vehicle from roll ing.
- S tronic- and tiptronic transmission : A l­
lowing the vehicle to ro ll when the en­
gine is stopped and the selector lever is

a gear that is su itable fo r the incline. H ill de­
scent contro l tries to ma inta in the speed ach­
ieved at the time o f braking, within phys ica l
and technical limitations. If may sti ll be nec -
essary to adj ust the speed with the brakes . ..,..
