Tether anchors and tether straps
Fig. 14 1 Tether anchors: recess flaps behind th e rear
seatbacks
The tether anchors for the rear seating posi­
tions are located in recesses in the rear win­
dow shelf
c> fig. 141
A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
h icle inter ior .
Forward facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
These new performance requirements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld res traints
w ill increase the risk of inju ry and death in
a c rash.
- Always follow the instructions p rov ided
by the manufacturer of the chi ld re ­
straint you intend to install in your Audi.
- Improper use o f ch ild restraint anchors
(incl uding tether anchors) can lead to in­
jury in a co llision. The anchors are de-

signed to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems
to one tether strap or tether anchorage.
- Never attach a tether strap to a tie -down
hook i n the Luggage compartment .
- Never use child rest raint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints .
- Never secure or attach any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.

• Depress the spring catch on the hook and re­
lease it from the anchorage.
({D Note
If you leave the child restraint with the
tether strap firmly installed for several
days, this cou ld leave a mark on the up­
holstery on the seat c ushion and backrest
in the area whe re the te ther strap was in­
s talled. The upholstery wo uld a lso be per­
manently stretched around the tether
s t rap. 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
h eed the child rest raint system manufactur­
e r's instructions carefully to determ ine how to
p rope rly insta ll the tethe r.

Electroni c inte raxle diff ere ntial lo ck */
s e le ct ive w heel t orqu e cont rol *
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque
contro l (all wheel drive) operates when driving
through curves. The front whee l on the inside
of the curve or both wheels o n the inside of
the curve are braked selectively as needed .
This minimizes s liding in the front wheels and
a llows for more precise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
Post-collision bra ke ass ist
"Post-collision brake assist" can ass ist the
driver during a collision by reducing the dan­
ge r of slipp ing and further co llision and by au­
tomatic braking.
"Post-collision brake assist" functions during
front, side and rear collis ions when the a irbag
control module a detects a trigger level and
the co llision takes place at a dr iv ing speed
faster than 6 mph (10 km/h). The braking of
the vehicle happen automatically via the ESC
as long as the ESC, the hydraulic brake sys­
tem, and the vehicle electrical system are not
damaged from the coll ision.
The fo llowing activ ities override the automat­
ic braking during a collision:
- If the dr iver presses the accelerator peda l.
T here is no a utomatic braking.
- When the force on the press brake pedal is
stronger than the b raking force initiated by
the system . The vehicle is manually braked .
- When the ESC is damaged and the "post­
collision brake assist" is not availab le.
A WARNING
- The ESC, ABS, ASR, EDL, electron ic inter­
axle d ifferential lock or select ive wheel
torque control cannot overcome the laws
of physics. This is espec ially important
on sl ippery o r wet roads.
If the systems
begin acting to stabili ze your veh icle, you
should immediately alter your speed to
match the road and traffic conditions . Do
not let the increased safety prov ided
tempt you into tak ing risks. This could
increase your risk of a collision.
- Please note the risk of a collision increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead .
ESC, ABS, the brake assist system, EDL,
electronic interaxle differentia l lock or
selective whee l to rque control cannot
p revent coll is ions.
- Press the acce lerator pedal carefully
when acce le rat ing o n even, slippe ry sur­
f a ces such as ice and snow. The drive
wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
col lision.
(D Tips
- ABS and ASR only function correc tly
when all four wheels are eq uipped w ith
identical tires. Different t ire sizes can
lead to a reduction in engine power.
- Yo u may hear noises when the systems
described are working .
- If the

Brakes
New brake pads
New brake pads do not achieve their full brak­
ing effect during the first 400 km. They must
be "broken in" first. However, you can com­
pensate fo r the slightly reduced braking force ""

188 Smart Technology
by pressing firmly on the brake pedal. Avoid
heavy braking during the break-in period.
Wear Brake pad
wear is largely dependent on the
way the vehicle is driven and on operating
conditions. This is especially true if you are
driving frequently in the city and on curves or
with a sporty driving style.
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight
condensation 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 with a few careful
brake applications.
At higher speeds and with the windshield wip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This action which is not felt by the driver hap­
pens at regular intervals and facilitates a bet­
ter reaction time for the brakes in wet weath­
er.
The braking effect can also be reduced if you
are driving on salted roads and you do not ap­ ply the brakes for long periods of time. The
layer of salt on the brake rotors and pads
must be worn off first when the brakes are ap­
plied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake ro ­
tors and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
high speeds is recommended to clean the
brake rotors and pads
Q &. .
Brake system malfunction
if you notice that the brake pedal travel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary.
Low brake fluid level
When the brake fluid level is low, malfunc­
tions in the brake system may occur. The brake fluid level is electronically monitored .
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING
-- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes

ALL wheel drive
(quattro)
Appl ies to vehicles: wit h all whee l drive
In all wheel drive, all four wheels are pow ­
ered .
General information
In all wheel drive, the driving power is divided
between all four wheels. This happens auto­
mat ica lly depending on you r driv ing behavior
as we ll as the current road conditions. Re fer
to
¢ page 185, Electronic stabilization con ­
trol (ESC) .
The all wheel drive concept is designed for
h igh engine power . Yo ur vehicle is exception­
a lly powerful and has excellent driving charac ­
teristics bot h under normal driving conditions
and on snow and ice . A lways read and fo llow
safety precautions
c> & .
Wint er t ire s
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
conditions . However, in winter we recommend
using winter or all season t ires on
all four
wheels, because this will improve the braking
effec t.
Snow cha in s
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive
c> page 241, Snow chains.
Replacing tire s
For vehicles with a ll wheel d rive, only wheels
with the same ro lling circumference should be
u sed. Avoid wheels with different tread
depths ¢
page 236 .
Offroad vehicle?
You r A udi is not a n offroad vehicle -there is
not enoug h ground clearance. For this reason ,
avoid difficu lt terrain. Refer to
c::> page 266.
A WARNING ~
- Also, in vehicles with a ll w heel drive,
adapt your driving sty le to the c urrent
road and traffic cond itions. Do not let
the increased safety provided tempt you into taking risks .
- The braking ability of your veh icle is lim­
ited to the traction of the wheels. In this
way, it is not different from a two wheel d rive vehicle . Do not be tempted to ac­
celerate to a high speed when the road is
slippe ry this inc reases the r is k of an acci­
dent.
- Note that o n wet s treets, the front
wheels ca n "hydrop lane " if driv ing at
speeds that are too high. Unlik e fron t
wheel drive vehicles, the engine does not rev higher sudden ly when the vehicle be­
g ins hydroplaning. For this reason, pay
attention to the road conditions regard­ less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventiona l energy
system is not d riven for a long time , the bat­
te ry is drained by equ ipment ( for example the
immobilizer) . In certain c ircumstances, there
cou ld may not be enough energy to start the
engine .

Driving and the
environment
The first 1,000 miles (1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the fir st 600 mil es
(1,000 kilometers):
.,. Do not use full throttle.
.,. Do not drive at engine speeds tha t are more
than 2/3 of the max imum permitted RPM .
.. Avoid high engine sp eeds .
From 600 to 1,000 mile s (1,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
max imum pe rm iss ib le road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transmission is i n N (Ne utra l) or in gear.
After the break- in period
.. Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ome ter scale
¢ page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
i n. How well this break-i n process is done de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1 ,5 00 k ilome ters).
(D Note
Extremely h igh engine speeds a re auto­
ma tica lly reduced. However, t he se rpm

Driving and the environment 193
@) For the sake of the environment
Do not drive with unnecessar ily hi gh en­
g ine speeds -upsh ifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be slippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing t he f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 kilomete rs) afte r they a re install ed.
New brake pads have to be "burnished in" be­
fo re they have optima l grab¢ .&. .
D uring the brea k-in pe riod, you should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
