rate . When the veh icle or parts of the re
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar with these requirements and we recom
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
pe rforms in a crash. For examp le, using tire-rim
comb inat ions not approved by Audi, lowering the
veh icle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control unit . Some suspension changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made . Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
ing when it should.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of serious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac
teristics as the components originally instal
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to: vehicles wit h knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .
Fig. 158 Driver 's knee air bag
The driver knee airbag is in the inst rument panel
u nderneath the steering wheel¢
fig. 158, the
airbag for the passenger is at about the same
height in the instrument pane l underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and lower thigh areas and supplements the protec
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 144, More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the dr iver or front passenger in
pos ition in a frontal collision so that the airbags
can provide supplemental protection .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu
pant restraint system in your vehicle. Always re
member that the airbag system can only help to
protect you if you are wear ing your safety be lt
and wea ring it properly. This is why you shou ld
always wea r your safety belt, not just because
t h e law requires you to do so ¢

Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require
ments for 3- and 6-year old children on the pas
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"s uppress ion " req uirements of the Safety Stand
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas
senger seat in child restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad ·
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to r ide. The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dangerous place for an infant or a
la rger child in a rearward-facing seat.
The vehicle's Advanced A irbag System has a ca
pac itive passenger detect io n system in the front
passenger seat cush ion that can detect the pres
ence of a baby or a child in a child restraint sys
tem on this seat .
The capacit ive passenger detection system regis
ters the changes that result in an electrical field
when a child, a child restraint, and a baby blanket
are on the front passenge r seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child restraint system resting on the seat. The meas
ured capacitance of a child restraint system var-
Child safety
ies depending on the type of system and specific
make and mode l.
T he elect rical capacitance of the various types,
makes, and models of child restra ints specified
by the U.S .National Highway Traff ic Safety Ad
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys
tem control unit together with the capacitances
typ ical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w it h a typical 1 year-old infant, the Ad
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic con
t rol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe
ty Standards and has been cert ified by its manu
facturer for use w ith an airbag . Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in exception
al circumstances you must use it on the front
passenger seat, carefully read all of the informa
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS . Make cer
tain that the chi ld and child restraint are correct
ly recognized by the capac itive passenger detec
t ion system in the front passenger seat, that the
front passenger a irbag is turned off, and that the
airbag status is always correctly s ignaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints have
been available over the years, new models are in
troduced regularly incorporating new and im
proved designs and older models are taken out of
production. Child restra ints are no t standardized.
Child restraints of the same type typically have
different weights and sizes and different "foot
prints", the size and shape of the bottom of the
chi ld restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossib le to certify compliance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been ..,.

Electronic Stabilization
Control (ESC)
Description
E SC helps to imp rove ro ad hold ing and vehicle
dynamics to help reduce the probab ility of skid
d ing and loss of veh icle control. It works only
when the engine is runn ing . ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicl e is begin ning to spin (yaw) o ut of contro l
and h elps you to ge t the veh icle b ack u nde r con
trol by se lectively bra king the wheels, and/or re
ducing engine powe r and providing steering as
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI in the in
strument cluster blinks when ESC is tak ing action
t o he lp you contro l the vehicle.
ESC has lim itations. It is important to remembe r
that ESC cannot overcome the laws o f physics. It
will not a lways be able to help out under all con
d itions you may come up aga inst . For example,
ESC may not always be ab le to help you master
situations where there is a sudde n change in the
coeff ic ie nt of fr iction of the road surface. W hen
there is a se ction of dry roa d that is sudde nly cov
e red with w ater, slush o r sn ow , ESC c annot pe r
form the same way i t wou ld on the dry s urface. If
the vehicle hydrop lanes (rides on a cushion of wa
ter instead of t he road su rface), ESC w ill not be
ab le to he lp you stee r the veh icle because contact
with the pavement has been inte rru pted and the
ve hicle cannot be b raked or steered . Dur ing fast
cor nering, part icu la rly on w inding roads, ESC
can not always deal as effect ive ly w it h difficult
d riving situat ions than a t lowe r speeds .
Always ad just yo ur speed and driving sty le to
road, traffic and weath er cond itions . ESC canno t
over ride the vehicle's phys ical lim its, increase the
ava ilab le traction, o r keep a ve hicle on t he road if
roa d depa rture is a re su lt of driver in attention .
I nstead, ESC imp roves the possibili ty of keep ing
180
t h e veh icle unde r contro l and on t he road d uring
extreme mane uvers by using the driver's steer ing
i nputs to help keep the veh icle go ing in the in
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rovide any assistance, you may not exper i
ence the be nefits of ESC.
ESC is switc hed on all the time. In certa in s itua
tions when you need less tract ion, you can sw itch
off ASR by press ing the button
[g] c:> page 181,
fig . 175 . Be sure to switc h ASR on aga in whe n
you no longer nee d less tract ion.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
A BS prevents the w heels from locking w hen bra k
i ng . The veh icle can still be steered even dur ing
hard braking. App ly steady p ressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake peda l ind icates that the system is act ing to
stab ilize the veh icle.
Brake a ssist system
The brake assist system can decrease b raking dis
tance. It increases b raking powe r whe n the dr iver
presses the b rake peda l quickly in emergency sit
uat ions. You must press a nd hold the brake peda l
u nt il the dange rous situation is over . In vehicles
with adaptive cruise co ntrol*, the brake ass ist
syste m is more se nsitive if the distance detected
t o t he veh icle ah ead is too sm all. On vehicle s wi th
a ctiv ate d a nd fun ctioni ng nigh t vis ion assi st*, the
brake assis t sys tem can respond more sensit ively
i f there is a warning .

The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow
erful and has excellent driving characterist ics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre
cautions
¢ ,&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con ditions . However, in winter we recommend using
winter or all season tires on all four wheels, be
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 233, Snow chains .
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid wheels with different tread depths
¢ page 225, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because th is increases the r isk of an acci
dent.
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two wheel drive vehi
cle. Do not be tempted to accelerate to a
high speed when the road is slippery this in
creases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high . Unlike front wheel drive
vehicles, the engine does not rev higher sud
denly when the vehicle begins hydroplaning.
Intelligent Technology
For this reason, pay attention to the road
conditions reg a rd less of your speed to re
duce the risk of an accident .

-Incorrect tire pressure in
creases tire wear and has a
negative effect on driving and

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operat ing properly . The TPMS mal
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
mately one minute and then remain cont inuously
illum inated . This sequence will continue upon
subsequent veh icle start-ups as long as the ma l
function ex ists .
When the malfunct io n indicator is illuminated,
the system may not be able to detect or signal low tire pressu re as intended . TP MS ma lfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate ti res or
wheels on the vehicle that prevent the TPMS
from functioning properly. A lways check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
t hat the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving .
The system uses sensors that measure the tem
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency .
The tire pressure monitoring system shows the current pressures and temperatures of the tires in the Infotainment system
c.>page 236. It also
compares the current t ire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
d ifferent from what is stored¢
page 237.
The system does not detect if the stored t i re
pressures match the recommended tire pres
sures. You must resave the tire pressures
c.> page 23 7:
-every time the tir e pressures change, for exam
ple when the load in the vehicle changes,
- after replac ing a tire, or
- if wheels with new wheel sensors are used .
236
A WARNING ,_
- The tire pressure monitoring system ass ists
the dr iver in monitoring tire pressures. The
driver is responsible for having the tires in
flated to the correct pressure.
- Do not change the t ire pressure when the
temperature of the tire is high . This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
ris k of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci
dent .
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to burst, for example. Inspect your t ires regu
larly.
@ Tips
- If tires are replaced, the sensors/va lves do
not need to be removed or replaced. Just re
placed the va lve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see your authorized Audi dealer
or authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors rep laced by an authorized Audi
dealer or authorized Audi Service Facility.

The specified tire pressure is the last tire pres
sure that was stored
¢ page 2 3 7 .
Note that the tire p ressure also depends on the
temperature of the t ire . Every 10 °C increase in
tire temperature results in the tire pressure in
creasing by approximate ly 0 .1 bar. The tire pres
sure increases as the eng ine becomes warmer
while driving.
