Instruments and warning/indicator lights
& WARNING (continued)
• Canada models: If the brake warning light «D> and the ABS
warning light come on together, the rear wheels could lock up
first under hard braking . Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­ diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low . If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected.
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle. Do not rely on strained brakes to respond with maximum stopping
power in critical situations. You must allow for increased braking
distances . The extra distance used up by fading brakes could lead
to an accident. •

Driver message appears and does not go out again
If this driver notification appears after the ignition is turned on or
while driving and does not go out again , the battery's state of
charge is not in the optimal range . Starting capability is restricted.
Have the battery checked by an authorized Audi dealer as soon as
possible .•

• Always remove objects from the instrument panel. Any items
not stored could slide around inside the vehicle while driving or
when accelerating or when applying the brakes or when driving
around a corner.
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake or accelerate.
• Any articles of clothing that you have hung up must not inter­
fere with the driver's view. The coat hooks are designed only for
lightweight clothing. Never hang any clothing with hard, pointed
or heavy objects in the pockets on the coat hooks. During sudden
braking or in an accident -especially if the airbag is deployed -
these objects could injure any passengers inside the vehicle. •

& 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. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
- Turn on the ignition.
- Pull lever into position
G) ~ page 149, fig. 157.
- Press the lever in the
0 or O direction to increase or
decrease your speed.
- Release the lever to save that speed.
This function makes it possible, for example, to save the speed you
want before driving on the highway. Once on the highway, activate
the cruise control by pulling the lever toward
G). •
Swit ching th e syst em off
Temporary deactivation
- Press the brake pedal, or
- Press the lever into posit ion
0 (not clicked into place)
~ page 149, fig. 157, or
- Drive for longer than 5 minutes at more than 5 mph
(10 km/h) above the stored speed .
Switching off completely
- Press lever into position
0 (clicked into place), or
- Switch the ignition off.
The system retains the saved speed if you deactivate the cruise
control temporarily . To resume the saved speed, release the brake

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 .

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 .,_

preparation. This function does not perform any emergency braking
m aneuv ers by i tse lf ; t he driver m ust alw ays app ly the b rake s.
& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything in the driver 's footwell or let anything fall
into it . An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being swit ched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped .
• Only u se floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS=>
& in
" Description " on
page 152.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear -end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations .
• Never allow the closing speed between you and other vehicles
to be so high that the Adapt ive 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 risk of a rear -end cra sh.

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehi cles too closely , particularly at h igher
speeds increases the risk of colli sions and serious personal injury.
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic .
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffic , road , weather and
lighting conditions .
• Never rely on the distan ce control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other acc ident situations .
• Never allow the closing speed between you and other vehicles
to be so h igh 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 risk of a rear-end crash .
