Fig. 117 Rear of the ve hicle: pos itio n of t he sensors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faste r a vehicle approaches,
the soo ner t he d isplay in the exter io r mirro r will
turn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
100
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles left behind
If you slowly pass a veh icle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph (1 S km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
T he display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph (15 km/h)).
Functional limitations
The radar senso rs are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain situations , the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that
i s cr itical for a lane change. For example:
- if the lanes are narrow or if your are dr iving on
the edge of your lane. If thi s is the case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if yo u are driving through a c urve . Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
- if side assist reacts to other objects (such as
high or disp laced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar senso rs
q fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . Do not
use side assist when towing a trailer. For infor ­
mation on cleaning, refer to
q page 184.
A WARNING
- Always pay attention to traffic and to the
area around your veh icle. S ide ass ist cannot
replace a dr iver's attention. The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuvers.

-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.
- Sid e assist cannot detect a ll vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, 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 are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window g lass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

A WARNING
- The rear view camera does not show the en­
tire area behind the vehicle¢
page 108,
fig . 123.
Watch out especially for small chil­
dren and animals . The rear view camera can­
not always detect them, posing risk of an
accident!
- Please note that objects not touching the
ground can appear to be further away than
they really are (for example, the bumper of
a parked vehicle, a trailer hitch, or the rear
of a truck). In this case, you should not use
the help lines to help with parking, which poses danger of an accident!
cg) Note
- Low obstacles already signaled by a warning can disappear from the system's detection
range as they are approached and will not
continue to be signaled. Objects such as
barrier chains, trailer draw bars, thin paint­
ed vertical poles or fences may not be de­
tected by the system, posing risk of dam­ age.
- In the MMI display, the direction of travel of the vehicle rear is represented depending on
the steering wheel angle. The vehicle front
swings out more than the vehicle rear. Main­
tain plenty of distance from an obstacle so
that your outside mirror or a corner of your
vehicle does not collide with any obstacles -
danger of accident!

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
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 164 or ¢page 171, fig. 165. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

M N
ci LL co
rl I.O
"' N
"' rl
In extreme cases, EDL a utomatica lly switches off
to help keep the brake on the braked whee l from
overheating. EDL w ill switch on again automati ­
cally when conditions have returned to normal.
Steering re commendat ion
The ESC helps to stabilize the ve hicle by chang ing
the steering torque.
I n vehicles with dynamic steeri ng*, ESC also
h e lps to stabilize the steering in critical s itua­
tions .
Electronic interaxle differential lock* /
sel ectiv e wheel torque control*
The electron ic in teraxle d iffe ren tial lock (front
wheel drive) or the selective wheel torq ue contro l
(all wheel drive) operates when driving through
curves. The front whee l on the ins ide of the cu rve
or both whee ls on the inside of the curve are
braked selectively as needed. Thi s allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
ci al ly impo rtant on slippe ry or wet roads. If
the sys tems begin acting to stabilize your
Switching on/off
Smart Technology
veh icle, you shou ld immediately change
your speed to matc h the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks . Do ing 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 losing con­
trol of the vehicle inc reases when dr iving
too fast, espec ially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth su rfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that can not always help to reduce
the risk of loss of vehicle cont rol.
{!) Tips
-ABS and ASR only work correct ly when a ll
four wheels are equipped w ith ident ica l
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

Trailer mode notes
Important to know
Your vehicle hand les differently when tow ing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trailer generally requires steering
action opposite to that when backing up your ve­
hicle without a trailer .
Maintain a greater distance between your vehicle
and the one in front of you. You wi ll need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot acce l­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your A udi may require
more frequent maintenance due to the ex­
tra load
¢ page 248 .
Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
.. Apply the foot brake.
.. Have someone place chocks under both the ve­
hicle and the trailer wheels.
Trailer mode
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
.. Turn the whee ls towards the curb .
.. App ly the parking brake.
.. Move the selector lever to P.
When restarting after parking:
.. App ly the foot brake.
.. Start the engine.
.. Move the selector lever to D/S .
.. Release the parking brake and slowly pull out
and away from the wheel chocks.
.. Stop and have someone retrieve the wheel
chocks .
(D Tips
If you move the selector lever of the automat­
ic transmission to P before applying the park­
in g brake and before blocking the wheels, you
may have to use more force later to move the
l ever out of the P position.
