Instruments and warning/indicator lights
• It comes on for approximately 15 seconds as a warning of
reduced ground clearance, if the dynamic mode is activated and if
the ignition is switched on~
page 207, "Chassis controls".
• If the warning/indicator light flashes in conjunction with the ;,
warning/indicator light, you should not drive the vehicle immedi­
ately in order to prevent damage to the underbody. The two
warning/indicator lights flashing together points to an extreme Low
level. A very
pronounced lowering of the vehicle (extreme Low level)
can result, for example, from a heavy load. As soon as the level has
returned to normal, the warning/indicator lights stop flashing, and
you can drive away.
0 Note
If the warning/indicator light flashes in conjunction with the
warning/indicator light, you should not drive the vehicle because
low-lying vehicle parts can bottom out as you drive over uneven
ground and be damaged as a result. •
High beam ~D
The ~D warning/indicator light illuminates when the high beams are
on or when you use the headlight flasher. For more information
about using the high beams, see~
page 77. •

This warning/indicator light monitors the ABS and the
electronic differential lock (EDL).
The warning/indicator light will come on for a few seconds when the
ignition is switched on . The light will go out after an automatic
check sequence is completed.
There is a malfunction in the ABS when:
• The warning/indicator light does not illuminate when you switch
on the ignition .
• The warning/indicator light does not go out after a few seconds.
• Th e warning/indicator light illuminates while driving.
The brake system will still respond even without the assistance of
the ABS system. See your authorized Audi dealer as soon as
possible to restore full braking performance.
For more information
regarding the ABS~
page 292.
The ABS warning light and the brake warning light come on
together. The ABS will not work and you will notice a change in
braking response and performance .
Malfunction in the brake system
If the brake warning light~ page 23and the ABS warning illuminate
together there may be a malfunction in the ABS, and there may also
be a malfunction in the brake system itself~& .
In the event of a
malfunction in the brake system the warning/indi ­
cator light

& WARNING (continued)
• Never use the cruise control when driving off-road or on
unpaved roads. The Cruise control is intended for use only when
the vehicle is being operated on paved roads , and is not suitable
for use off -road or on unpaved roads .
[ i J Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down ­
shift to a lower gear or use the brakes to slow down. •
Changing speed
-Press lever in the 0 or O direction ~ page 149, fig. 157
to increase or decrease your speed.
- Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The symbol will go out but the saved speed will be retained. •

Adaptive Cruise Control
Speed and distance control system
Applies to vehicles: with Adaptive Cruise Control
Description
The Adaptive Cr uise Contr ol driver assi stance program is
a combined speed and distance control system .
Fig . 159 Fron t
bu mper : Po siti on of
r a d ar sen sor (n ot
vi sibl e from out side)
Adaptive Cruise Contro l can help make driving more relaxed and
less tiring, particularly during long trips on interstates or other
highways that are generally straight . T he system can also assist in
stop and go traffic.
The Adaptive Cruise Control works within a speed range between 0 and 95 mph (150 km/h). Set ACC to maintain a constant, legal travel
speed between 20 and 95 mph (30 -150 km/h) that is appropriate for
prevailing traffic conditions. Se lect a following distance to the
vehic le ahead and ACC will adjust your speed to maintain that
d istance down to a stop . At a speed below 20 mph (30 km/h), the
m ini mum speed setti ng of 20 mph (30 km/h) will be selected auto ­
matically.
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times. H
ow doe s it work ?
You can operate the Adaptive Cruise Control using the lever on the steering whee l column =:>
page 156, "How is the speed st ored?" and
=:>
page 158, "How is the distance (time interval) set? ".
Driver information
I mportant informa tion is brought up in the speedometer and in the
instrument clus ter d isplay as the vehic le is being driven
=:>
page 160, "Driver information".
What is import ant for you to know
T he Adaptive Cruise Contro l is set with system -specified limits; that
is, as a drive r, you will have to adjust the speed and distance to the
vehic le ahead in some instances=:>
page 164, "Driver intervention
prompt" and ~
page 165, "Sys tem li mita tions" .
& WARNING
Improper u se of the Adaptive Cruise Control can cause collisions ,
other a ccidents and serious personal injury .
• Alway s re member that the Adaptive Crui se Control has limit s -
it will not slow the vehicle down or maintain the set distance
whe n you driv e to wards an ob stacle or something on or ne ar the
road that is not moving , such as vehi cle s stopped in a tr affic j am ,
a stalled or disabled vehicle.
• Alway s rem ember that the Adaptive Cruise Control cannot
detect a veh icle that i s dri ving towards you in your traffic lane and
that it cannot detect narrow v eh icles su ch a s motorcycles and
bicycle s.
• Never driv e at speed s that are too fa st for tr affic , road and
weather condition s.
• Never follow a vehicle so closely th at you cannot stop your
vehicle safel y. The Adaptive Cruise Control cannot slow or br ake _.,

& W ARNING (continu ed )
the veh icle safely when you follow another vehicle too closely .
Always remember that the Adaptive Crui se Control has a braking
power th at is only about 30 % of the vehicle 's maximum braking
ability . The automatic braking function cannot bring the vehicle to
a sudden or emergen cy stop . Always be prepared to bra ke and
take evasive action to avoid collisions and other accident situa ­
tions .
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to
slow your vehicle safely . If closing speed is too high , you must
apply the brakes yourself to reduce the ri sk of a rear -end crash .
• Never rest your foot on the accelerator pedal , especially when
the Adapt ive Cruise Control is being used . Pressure on the a cceler ­
ator will override the ACC braking function and prevent the brakes
from being appl ied when ACC detects a situation when the brakes
must be applied.
• Never use Adapt ive Cruise Control when you cannot drive
safely at a steady speed , including on city streets , on winding
roads or when road conditions are poor (for example , on ice,
gravel, in fog , heavy r ain or on wet roads that increase the risk of
hydroplaning
I.
• The radar sensor's vision can be reduced by rain , snow and
heavy road spray . These and similar conditions can prevent vehi ­
cles up ahead from being accurately detected and in some cases
they may not be detected at all . Do not use ACC when the radar
sensors cannot accurately detect veh icles moving ahead of you in
traffic.
• Always turn off Adaptive Cruise Control when entering turn
lanes , exit lanes and construction zones or in similar situations
because the vehicle will automati cally accelerate to the stored
speed when the road ahead is clear.
• To prevent unintended operation , always switch ACC off when
it is not be ing used .
Controls and equip ­
ment
[ i ] Tips
• For sa fety reasons , the sto red speed is de leted w he n th e ig nit ion
is turned off.
• The E lectronic Stabilization Program (ESP) and the Anti -Slip
R egu lation (ASR) cannot be deacti vated when the Adaptive Cruise
Co ntrol is sw itc hed on . If the ESP and the Anti-Slip Regula tion (AS R)
has been deactivated and you then switch on the Adaptive C rui se
Contro l, t he ESP func tion w ill also be act iva ted automat ica lly .
• Damage caused by accidents an d so me mino r co llisions can
affect t he radar sensor sett ings and cause the sys tem to ma lfun c­
tion or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should stil l check before driving to make sure it is free of ice and
s n ow. If necessary, clean the area near t he radar sensor carefully
~ page 15 2, fig. 159 .
• To ensure that the radar sensor is not blocked, foreign objects
(e .g. stickers, la rger l icense plate mount s, add -on pa rts) must not
cove r th e area near t he radar sensor~ page 152, fig. 159. The area
nea r the rada r sensor must not be painted, either .

Ap plies to vehi cles : wi th Ad aptive Cruise Co nt rol
How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sens or.
Fig. 160 Bas ic p rin­
ci pl e diagra m: R adar
s en sor measur eme nt
ra nge
Adaptive Cruise Contro l uses a radar sensor in the fron t of the
vehic le=> fig. 160. The system has limitations=>
page 165. Things
t hat are not moving in your lane and in your direction of travel will
not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made. If a measurement
is not possible, the system cannot respond and wil l not react to a
vehic le or something else up ahead.
Op en ro ad
When the road is clear, the Adaptive Cruise Contro l works like cruise
control. It maintains a constant target speed specified by the driver.
D rivi ng in t raffi c
If a slower vehicle driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)=>
page 164,
"Driver intervention prompt" and=> page 165, "System l imitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed wh ile adjusting=>
& in "Description" on
page 752 .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel­
era tes up to the speed that you have set .
If the vehicle ahead s lows to a stop, ACC wi ll slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabil ities . ACC will not make an emergency stop. The text
message
ACC off : manu al c ontro l! appears in the instrument c luster
display . Once the veh ic le stops, you must depress the brake peda l
to prevent the vehicle from moving forward or "creeping" .
Depressing the brake pedal turns off ACC. When the veh ic le ahead
acce lerates you can reactivate ACC =>
page 157, as soon as your
vehic le has reached a speed of 1 mph (2 km/h).
S ituati ons re quir in g dri ver int erve ntion
In some situations you will have to use the footbrake to slow the
vehic le down in order to keep a safe distance from vehic le in front
of you or to avoid a rear-end collision. In this situation, a symbol
appears and a warning tone sounds=>
page 164.
Passing anoth er v ehicl e
If you move into the passing lane and no vehicle is detected ahead,
the Adap tive Cruise Contro l accelerates to the speed you have set
and maintains it.
Ov erriding A CC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you re lease the accelerator peda l, the system
adjusts back down to the speed you previously set.
Redu cin g stopping di stan ce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum d istance, the brakes are automat ically
prepared for emergency braking by the driver. The brake pads are
moved very c lose to the brake discs without actually braking the
vehic le. This brake assis tant feature reacts more quickly to the
driver's braking, and also works when Adap tive Cruise Contro l is off.
The stopping distance is reduced as a result of this advance brake .,_
