Tether anchors and tether straps
Fig. 173 Te the r ancho rs: att achm ent hook locatio ns be
hi nd the rea r seatbacks
The tether anchors for the rear seating positions
are located on the backside of the rear seatbacks
¢ fig. 173.
A tether is a stra ight or V-shaped strap that at
taches the top part of a child restra int to special
anchorage points in the vehicle .
The purpose of the tether is to reduce the for
ward movement of the child restra int in a crash,
in order to he lp red uce the risk of head injury
that could be caused by striking the veh icle inte
rio r.
F orwa rd facing ch ild restraints manufactured af
ter September 1, 1999, are required by U.S. fed
eral regulations to comply with new child head movement performance requirements. These
new perfo rmance requirements make a tether
necessary on most new child safety seats .
A WARNING
Improper installation of child restraints will
increase the r isk of injury and death in a
crash .
- Always follow the instructions provided by
the manufacturer of the child restra int you
intend to install in your Aud i.
- Improper use of child restra int anchors (in
cluding tether anchors) can lead to injury in
a collision . The anchors are designed to
withstand only those lo ads imposed by cor
rectly fitted child restra ints.
- Never mou nt two chi ld restraint systems on
one LATCH lower a nchor po int.
Ch ild sa fety
- 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 anchorages
to secure safety be lts or other kinds of occu
pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If you must install a rearward facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PAS SEN GER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear seating position and have the a irbag system
inspected by your Audi dealer.

Child safety
Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.
.,. Depress the spring catch on the hook and re
leas e it from the anchorage.
(D Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently 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 systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc
tions carefully to determine how to properly in
stall the tether.
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, or
door.
- If you must install a rearward facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer.

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 .
Anti-slip regulation (ASR )
ASR reduces e ngine powe r whe n the d rive whee ls
begin s pin nin g and ad apts the force to the ro ad
con ditions. This m akes i t easier to s tar t, a cce ler
ate and drive up incl ines .
Electronic differential lock (EDL)
E DL applies t he b rakes to a whee l th at s tarts
sp inning a nd transfers the dr ive power to the
othe r drivi ng whee ls . This fu nction is n ot a vail a-
b le at hig he r sp eeds . .,..
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa
tions.
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 selectively as needed. This al
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the risk of sliding and of other
coll isions after an accident.
If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri
cal system are not function ing .
Switching on /off
Intelligent Technology
A WARNING
-- The ESC and its integrated systems cannot
overcome the limits posed by natural physi
cal laws. This is especia lly important on slip
pery or wet roads. If the systems begin act
ing to stabilize your vehicle, you should im
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking r isks. This cou ld increase your risk of
a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when dr iv
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
vent collisions -there is still a risk of acci
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The dr ive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
i n crease the risk of a collision .
(j) Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc
tion in engine power.
- You may hear noises when the systems de
scribed are working.
£SC turns on automatically when you start the engine.

The ESC is designed to function in levels. Depend
ing on the level that is se lected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de
pending on the level.

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢&, . The b reak-in pe
riod can be considerably longe r fo r vehicles with
182
ceramic brake rotors* . You can compensate for
this slightly reduced braking power by pushing harder on the brake pedal. Avoid heavy braking
l oads during the break-in per iod.
Op erating c ondition s and dri ving habits
The brak es on today 's automobiles are still sub
ject to wear, depending large ly on operating con
dit ions and driving habits ¢&, . On vehicles that
are either driven mostly in stop-and-go city traf
fic or are driven hard, the brake pads shou ld be
checked by your authorized Audi dealer more of
ten than specified in the
Warr ant y & Maint e
nance booklet .
Failure to have your brake pads
i nspected ca n result in red uced b rake perfo rm
ance.
On steep slopes, you should use the brak ing ef
fect of the engine . Th is way, you prevent unnec
essa ry wea r on the brake system. If you must use
you r brakes, do not ho ld the brakes down contin
u ous ly. P ump the brakes at intervals.
Operating noi se
Noises may occur when brak ing depending on the
speed, braking force and outside conditions such as temperature and h umid ity.
Due to the nature of the mater ials used in ceram
i c brake rotors*, no ises may become more appa-
rent at low speeds. ..,.
Effect of wat er and road salt
In ce rtain situations, for example after driving
through water, in heavy rain, afte r ove rnight con
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first w ith a few careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. Th is occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coat ing from brake discs
and pads with a few cautious applications of the b rake ¢_&. .
Due to their surface character istics, ceramic
brake roto rs* absorb mo isture in such condit ions.
This can cause a temporary reduc tion in braking
force compared to dry brakes. You can compe n
sate fo r th is by press ing the b rake peda l harder.
Corrosion
There may be a tende ncy for d irt to bu ild up on
the brake pads and corros ion to form on the discs
if the car is not dr iven regularly or only fo r sho rt
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is adv isable to
clean off the pads and discs by brak ing firmly a
few t imes from a mode rately h igh speed ¢,& .
Faults in the brake system
If you should notice a sudden increase in brake
pedal travel, then one of the two brake c ircuits
may have failed
¢ ,& .
Low brake fluid le vel
Malfunct ions can occur in the brake system if the
brake fl uid level is too low. The brake fluid level
is monitored electronically .
Intelligent Technology
Brake booster
The brake boos ter works w ith v acuum press ure
which is crea ted on ly when the engine is running

Brake lining wear status
Brake lining wea r may be chec ked by visua l in
spe ct ion of the condition of the brake pads
t hr ough the openings in t he wheel. If necessary,
the wheel may be removed for this inspection
¢ page 243, Replacing wheels .
_8 WARNING "'----
-New b rake pads don't have the best stop
p ing power and must be "broken-in" d uring
the initial 250 miles (400 km). The b reak-in
period can be considerably longer for
veh icles with ceramic brake roto rs*. You can
compensate for this by pressing the brake
pedal mo re firmly. This also applies late r
when new p ads are inst alled.
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit io ns pe rmit. O ther ro ad
users m ust no t be put at r is k - you may
cause an accident!
- Before descending a steep g rade, reduce
speed and shift transmission into a lower
gear o r lower driving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This cou ld cause t he b rakes to get
hot and dimin ish braking effic iency.
- Do not " ride the brakes" by rest ing your foot
on the pedal when you do not intend to brake. This may cause the brakes to over
heat, premature wear and increased stop
p ing distance .
- Unde r certain climatic and ope rating condi
tions such as passing t hrough water, d riving
i n heavy rain o r afte r wash ing the veh icle,
the effectiveness of the brakes ca n be re
duce d. In winter, ice can accum ulate on the
b rake pads, lin ings, discs and dr ums. Care
fu lly apply brakes for a test. Brakes will d ry
an d ice coatings will be cleaned off after a
few ca refu l brake applications.
183
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 .
