A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
specia l anchorage points in the veh icle.
The purpose of the tether is to reduce the for·
ward movement of the ch ild restra int in a
crash, in order to help reduce the r isk of head
in ju ry that could be ca used by s tri king the ve
hicle interior.
Forward facing child restra ints manufactured
after September 1, 1999, a re required by U .S .
federal regulations to comply with new child
head movement performance requirements.
These new performance requ irements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a crash.
- Always follow the instructions prov ided
by the manufacturer of the ch ild re
stra int you intend to install in your Audi.
- Improper use of c hild restra int anchors
(including tether anchors) can lead to in ·
jury in a co llision. Th e anchors are de·
sign ed to withstand only those loads im
posed by cor rect ly fi tted ch ild restraints.
- Never mou nt two chi ld restraint systems
on one LA TCH lower anchor po int. -
Never attach two child restraint systems
to one tether strap or tether anchorage .
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho
rages to secure safety belts or other
kinds o f occupant restraints.
- Never secure or attac h any luggage or
other items to the LATCH lower ancho
rages or to the tether anchors.
- If you must install a rearwa rd facing
child safety seat on the front passenger
seat because of exceptional c ircumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately insta ll the rear-fac ing ch ild

release it from the anchorage .
0 Note
If you leave the child res traint with the
tether strap firmly insta lled for severa l
days, this cou ld leave a mark on the up
holstery on the seat cushion and backrest
in the area where the tether strap was in
stalled . The upholstery would a lso be per
manently stretched around the tether
strap . This applies especially to leather
seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint sys
tems come with a tether. P lease read and
heed the child restraint system manufactur
er's instructions carefully to determine how to properly install the tether .
A WARNING

Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy
ment time is adapted in
Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli
sion with the vehicle immediately ahead is al
so calculated . If the system senses an immi
nent collision the following functions can be
tr iggered :
- Braking guard c::>poge
88
-Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail
able. See your authorized Audi dealer immedi
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob
jects. This increases the risk of a colli
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path c::> page
82.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi
tions can prevent vehicles from being ac
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au
thorized Audi dealer check to make sure
that the system is working properly.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da
ta Recorde r (EDR), ins talled by some manu
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re
corders".
Some state laws restr ict the retr ieval or down
loading of data stored by EDR's that were in
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, em is
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op
erat ion for diagnostic and repa ir purposes.
The recording capacity of the electronic con
trol modules is limited to data (no sound is re
corded) and only a small amount of data is ac
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith special equip
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of ve hicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course. The in
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in
stead of the road surface), ESC will not be
able to help you steer the vehicle because con
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESC can
not override the vehicle's physical limits, in
crease the availab le tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibil ity of keeping the vehi cle under con
trol and on the road during ex treme maneu
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi
ence the benefits of ESC.

Braking
General information
What affects braking efficiency?
-
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat
ing condit ions and driving hab its
c::> .&. . On
vehicles that are either driven most ly in stop
and-go city t raff ic or are driven hard, the
brake pads should be checked by your author
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter
vals .
Moisture o r road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in .,,_
196 Intellig ent technolog y
-Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Electro-mechanical

The electro-mechanical power assist helps
the driver when steering.
Power stee ring adapts electronically based on
the veh icle speed.

General info rmation
With a ll Wheel Drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
condit ions at the time. See also ¢

Always read and follow safety precautions
Q _& .
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea
son tires) for improved driveability and brak
ing : these tires must be mo unted on
all fou r
wheel s. See also ¢ page 255 , Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
with all-wheel drive r::¢,
page 256, Snow
chains.
Replacing wh eels /tires
Vehicles with all-wheel drive m ust always
have ti res of the same s ize. A lso avo id tires
with different t read depths . For detai ls see
page r::¢,
page 251, New tires and replacing
tires and wheels .
Off-Road driving?
You r Audi does not have e nough ground clea r
ance to be used as an off-road vehicle . It is
t h erefore best to avoid rough tracks and un
even terrain as much as possib le . Also refer to
r::¢, page 200. ..,_
A WARNING ,~
Always adjust your driving to road and traf
fic conditio ns. Do not let the extra safety
a ff orded by all-wheel dr ive tempt you into
taking extra risks.
-Although the all-wheel dr ive is very ef
fec tive, a lways remember that b raking
capacity is limited by t ire traction . You
sho uld the refore no t dr ive at excess ive
speeds on icy or sl ippery road surf aces.
- On wet road su rfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aq uaplaning). If this sho uld occ ur, you
will have no warning from a sudden in
crease in engine speed as with a front
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con
ditions - risk of c rash.
Energy management
Starting ability is optimized
E nergy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a veh icle wit h a conven tional energy system
is not d riven for a long period of time , the bat
tery is discha rged by idling c urre nt cons umers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient ene rgy
avai lab le to start the engine.
I ntell igent energy ma nagement in your vehi
cle hand les the d istribution of electrical ener
gy . Starting abi lity is mar ked ly improved and
the life of the battery is extended .
B asically, energy management consists o f
battery diagno sis , idling current manage
ment
and dynamic ene rgy man agement.
Battery diagnosis
B atte ry d iagnosi s con tinuously dete rmines
the state of the battery. Se nso rs dete rm ine

temperature . This de termines the current
state of charge and the power of the battery.
Idling current management
Idli ng cur ren t management reduces energy
consump tion while the vehi cle is st anding.
With the ig nition switched o ff, it controls the
energy supply to the various electrical compo
nents . Data from batte ry diagnosis is consid
ered.
Depend ing on the ba ttery's state of cha rge,
individual consumers a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energy management
While t he vehi cle is being dr iven, dyn ami c en
ergy management distr ib utes the energy gen
erated according to the needs of the individ u
al components. It regulates consumption, so
that more e lectrical energy is not being used
than is being generated and ensures an opti
mal state of charge for the battery.
(D Tips
- But even energy management cannot negate the limits of physics. Consider
that the power and life of a battery are
lim ited.
- If start ing ability is t hreatened, the indi
cator light(•] appears ¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in s hort-distance
driv ing, in city traff ic and during the cold time
of year. Ab undant electrical energy is re
quired, but on ly a little is generated .
It is also
crit ical if the engi ne is not r unning and elec tri
ca l components are tu rned on . In this in
s tance ene rgy is be ing consumed b ut none is
being genera ted.
It is in precisely these situations that you will
notice ene rgy management active ly reg ulat-
i ng t he d istr ibu tion of ene rgy. ..,_ •

198 Intelligent technology
Vehicle stands for an e xte nded period
If you do not drive you r vehicle over a pe riod
of several days or weeks, elec trical compo

This reduces energy cons umption and main
tains starting capab ility over a longer period.
Some of the conven ience f unctions may not

power seat adjustment. T he conven ience
f u nctions w ill be ava ilable again when you
switch on t he ignit io n and start the engi ne.
With the engine turned off
If you listen to t he radio, for example, with
the eng ine turned off or use othe r MMI func
tions, the battery is b eing d ischa rged .
I f starting capab ility is jeopa rdized due to en
ergy consumpt ion, the following warning ap
pears in the MMI disp lay:
Please start the engine soon or the system
will be turned off.
T he warning ind icates that the system will be

you wish to cont inue using the f unctions, you
have to start the engine.
With the engine running
A ltho ugh elect ric al e nergy is genera ted when
the veh icle is being driven, the bat tery can be
come d ischarged. This ha ppens most ly w hen
litt le energy is be ing generated and a great
deal consumed and the battery 's state of
charge is not optimal.
To br ing the ene rgy balance back into equili
brium, cons umers which require especially
large amo unts of energy are temporarily cut
back or switched off. Heating systems in par
