Audi adapt ive cru ise control and brak ing gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydrop lan
ing). Using the system under these condi
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora
rily when driving in turn ing lanes, on ex
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak
ing guard do not react to people, animals,
objects cross ing the road or oncoming ob
jects .
- The function of the radar sensor can be af
fected by reflective objects such as guard rails, the entrance to a tunnel , heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un
der these conditions.
- To prevent unin tended operation, always
switch adaptive c ruise control off when it is
not be ing used .
(D Note
The sensor can be displaced by impa cts or
damage to the bumper, wheel housing and
underbody . That could affect the adaptive
cruise contro l system and braking gua rd . Have
your authorized A udi dealer or authorized
Audi Service Facility check their function .

In curves
Applies to vehicles: with Audi adapt ive cruise contro l
Fig. 117 Example: dri ving in to a c urve
When dr iving into a curve c:::> fig. 117 and out of a
curve, the adaptive cruise control may react to a
vehicle in the next lane and apply the brakes . You
can override or prevent the braking by pressing
the accelerator peda l briefly .
Stationary objects
Applies to vehicles: wi th Audi adaptive cruise control
Fig . 118 Example: objec t cha ngin g la n es and sta tionary
ob jec t
The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, if ave
hicle @, which has already been de tec ted by the
adap tive cruise con trol, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to
the stat ionary vehicle.
Audi side a ssist
- Improper reliance on the side assist system
can cause collisions and serious personal in
jury:
- Never rely only on side assist when chang
ing lanes.
- Always check rear view mirrors to make sure that it is safe to change lanes.
- Side assist cannot detect a ll vehicles under
all conditions -danger of accident!
- Please note that side assist indicates there
are approaching vehicles, o r vehicles in your
blind spot, only after your vehicle has
reached a dr iv ing speed of at least 19 mph
(30 km/h).
- In certa in situations, the system may not
func tion or its funct ion may be lim ited. For
example:
- if vehicles are approaching or be ing left
behind very qu ickly. The display may not
turn on in time .
- in poor weather condit ions such as heavy
ra in, snow or heavy m ist .
- 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 ar e outside of the sensor
range.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov ing , servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system and prevent that system from working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce
dures can increase the risk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
- Never cover, obstruct, or change the steer
ing wheel horn pad or airbag cover or the in
strument panel or modify them in any way .
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov
ering the airbag units .
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois
tened with plain water. Solvents or cleaners could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or electrical system (in
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
Airbag system
who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that you see your au
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can
inflate without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately by an authorized Audi dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technician who has the technical
information, training and special equipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag components must be performed by qualified work
shops only. Make sure that any airbag serv
ice action is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE
PLACEMENT RECORD.
- In accidents when an airbag is deployed, the
vehicle battery separates the alternator and
the starter from the vehicle electrical sys tem for safety reasons with a pyrotechnic
circuit interrupter .
- Work on the pyrotechnic circuit interrupt
er must only be performed by a qualified
dealer -risk of an accident!
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) reinfor
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti
cal s ituations such as the vehicle oversteering
and understeering or the wheels sp inning. The
veh icle is stab ilized by applying the brakes or re
ducing engine torque. Once the ESC is act ive, the
indicator light
m blinks in the instrument clus
ter.
The fol low ing systems a re integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up when
brak ing . The vehicle can still be steered even dur
ing hard braking. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is help
ing you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking d is
tance . It increases braking power when the dr iver
presses the brake pedal quick ly in emergency s it
uations. You must press and hold the brake pedal
unti l the situation is over. In vehicles w ith adap
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve
hicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler
ate and drive up hills.
Smart Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other whee ls.
This function is not avai lable at higher speeds .
In extreme cases, EDL automatically sw itches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati
ca lly when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
On vehicles with dynam ic steering*, ESC helps
stab ilize the steer ing in crit ical situat ions .
Selective wheel torque control
Selective wheel torque control is used when driv
ing on curves. The front wheel on the inside of
the curve or both wheels on the inside of the
curve are braked select ively as needed. This al
lows more precise driving in curves. The applica
ble system may not activate when driving in wet
o r snowy conditions .
A WARNING
-
-The ESC and its integrated systems cannot
overcome the laws of physics. This is espe
cially important on slippery or wet roads. If
the systems begin acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of los ing con
trol of the vehicle increases when driving
too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions - there is st ill a risk of acc idents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function indicator is combined with the low tire pressure telltale . When the system detects a
malfunct ion, the telltale will flash for approxi
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle start-ups as long as the mal
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
