Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward -fac ­
ing child restraints that support the back,
neck and head in a crash.
Fig . 159 Sche matic overv iew: rearward-fac ing infant

Infants up to about one year (20 lbs . or 9 kg)
are best protected in special infan t carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re­
straints in which the ch ild faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash

The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.

A WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe­
ty and well-being require that the follow­ ing special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a
passenger front and side airbag.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble before installing the child restraint.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position.
- Make sure that the
PASSENGER AIR BAG

Child Safety 169
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and
80 lbs . (18 kg and 36 kg) who are less than 4
ft. 9 in. (57 inches/1.45 meters) tall.
Fig. 162 Rear seat: c hild p roperly restrained in a boos ­
ter seat
The vehicle's safety belts alone will not fit
most children until they are at least 4 ft. 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs.
(36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies and the safety belt can help protect them in a
crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to re­
strain a child on a booster seat.
.. The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body .
It must never lie across the throat or
neck . The lap belt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary .
.,. Secure unused safety belts on the rear seat
r:1;>page 166 .
Children up to about 40 lbs. (18 kg) are best
protected in child safety seats designed for
their age and weight. Experts say that the
skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without
a suitable child restraint.

1 70 Child Safety
It is usually best to put these children in ap­
propriate booster seats. Be sure the booster
seat meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the child's body in the right places. The
routing of the belt over the child's body is very
important for the child's protection, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle 's three point lap and shoulder belts .
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regard­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point lap and shoulder belts. The child 's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
child's stomach or abdomen.
In a crash, airbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the air­ bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an
inflating airbag. When an occupant is too
close, he or she will be struck violently and
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible. By keeping room between
the child's body and the front of the passen­
ger compartment, the airbag can inflate com- pletely and provide supplemental protection
in certain frontal collisions.
A WARNING
--
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per body.
It must never lie across the
throat or neck. The lap belt must lie
across the pelvis and never across the
stomach or abdomen. Make sure the belt
lies flat and snug. Pull on the belt to
tighten if necessary .
- Failure to properly route safety belts
over a child's body will cause severe inju­ ries in an accident or other emergency
situation
~ page 132 .
-The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat .
- Children on the front seat of any car, even with Advanced Airbags, can be seri­
ously injured or even killed when an air­bag inflates .
- Never let a child stand or kneel on any
seat .
- Never let a child ride in the cargo area of
your vehicle.
-Always remember that a child leaning
forward, sitting sideways or out of posi­ tion in any way during an accident can be
struck by a deploying airbag. This will re­
sult in serious personal injury or death.
- If you must install a booster seat on the
front passenger seat because of excep­
tional circumstances the
PASSENGER
AIR BAG OFF
light must come on and
stay on, whenever the ignition is switch­
ed on .

Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up, against or very near the in­
strument panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and

Braking
What affects braking efficiency?
Ne w brake p ads
During the first 250 miles (400 km), new
-
brake pads do not possess the ir full brak ing
effect, they have to be "broken in" first
c:> .&.. .,.

182 Intelligent technology
You can compensate for this slightly reduced
braking power by pushing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warra nty & Maint enance booklet . Failure
to have your brake pads inspected can result in red uced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessa ry wear on the brake system. If you
must use yo ur brakes, do not hold the brakes
down continuously . P u mp the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature and humidity .
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight
condensat ion or after washing your car, the
b rak ing effect can be reduced by moistu re or
ice on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few caref ul
b rake app lications .
At higher speeds and with the w indshield w ip­
e rs turned on, the brake pads press agains t
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for better brake response time under wet condit ions.
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 sa lt coating from brake d
iscs and pads with a few cautio us ap­
plications of the brake
Q ,&. .
Corrosion
The re may be a tendency for dirt to bu ild up
o n the brake pads and corros io n to fo rm on
the d iscs if the car is not driven regu la rly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed

Lo w brake fluid lev el
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake f lu id
level is monitored electronically.

Driving with your
quattro®
App lies to vehicles: with all-wheel dr ive
-
With all-wheel drive, all four wheels are driv­
en.
General information
With all-wheel drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
conditions at the time . See also
¢ page 179.
A center differential distributes the driving
power variably to the front and rear axle . It
works together with selective wheel torque control, which activates when driving through
curves
c> page 180. With the sport differen­
tial*, power distribution to the rear wheels is
variable and can be adjusted with drive select
c:>page 107.
The all-wheel drive concept is designed for
high engine power . Your vehicle is exception­
ally powerful and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions ¢
&.
Winter tires
When driving in the winter , your vehicle with
all-wheel drive has an advantage, even with
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 mounted on all four
wheels. See also ¢ page 242, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive¢
page 243, Snow
chains .
Replacing wheels/tires
Vehicles with all-wheel drive must always
have tires of the same size. Also avoid tires
with different tread depths. For details see
page
c> page 238, New tires and replacing
tires and wheels.
Off·Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle.
It is
therefore best to avoid rough tracks and un­
even terrain as much as possible. Also refer to
c:> page 187.
_& WARNING
-Always adjust your driving to road and traf-
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is limited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive vehicle. Always drive at speeds which are suited to the road con­
ditions - risk of crash .
