- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt midway over the child's shoulde r.
- Always make sure that the shoulder portion of the safety belt never rests against or across the child's neck.
- Always make sure that the child can properly wear the lap
portion of the belt low across the thighs or pelvis and
never over the stomach or abdomen.
Children up to at least 8 years old (over 40 lbs. or 18 kg) are best
protected in child safety seats des igned for their age and we ight.
Experts say that the skeletal structure, particularly the pelvis, of
these ch ild ren is not fully developed, and they must not use the
veh icle safety belts w ithout a suitable ch ild restraint .
Children up to about 40 lbs (18 kg) are best protected in child safety
seats des igned for their age and weig ht. Expe rts say that the skeletal
structure, particularly the pelvis, of these children is not fully devel­
oped, and they must not use the vehicle safety bel ts witho ut a suit­
able child restraint .
It is usually best to put these chi ldren in appropriate 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 sho ulder parts of the safety bel t so that they pass
across the child's body in the right places. The routing of the belt over
the ch ild 's body is very impo rtant for the chi ld's p rotection, whether
or not a booster seat is used. Children age 12 and under must always
ride in the rea r seat.
Chi ld ren who are at least 4 ft. 9 in . (57 inches/1.45 meters) tall can
generally use the vehicle's three point lap and shoulder belts . Never
use the lap belt port ion of the vehicle 's safe ty belt alone to restra in
any child, regard less of how big the child is. Always remember that children do not have the pronounced pelvic structure requ
ired for the
proper func tion o f lap belt por tion of the vehicle's three poin t lap and
shoulder belts . The ch ild's safety absolutely requires that a lap belt
portio n of the safety be lt 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 m ust inflate with in a blink of an eye and with
considerable force. In order to do its job, the airbag needs room to
inflate so tha t it w ill be the re to protect t he occ upant as the occupant
moves forward into the a irbag.
A vehicle occupant who is out of position and too close to the airbag gets in the way of an inflating a irbag. When a n occupant is too close,
he or she will be struck violently and will receive serious or possibly
even fata l injury.
In order for the airbag to offer protection, it is important that all
vehicle occupants, especia lly any ch ild ren, who must be in the front
seat because of exceptional circumstances, be properly restra ined
and as far away from the airbag as possib le .
By keeping room
between the child's body and the front of the passenger compart­
ment, the a irbag can inflate completely and provide supplemental
protection in certa in frontal collisions .

• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates .
• Never let a child stand or kneel on any seat, for e xample the
front seat.
• Ne ver let a child ride in the cargo area of your vehicle .
• Alway s remember that a child leaning forward, sitting side­
ways or out of position in any way during an accident can be struck
by a deploying airbag . This will result in seriou s personal injury or
death.
• If you must install a booster seat on the front pas senger seat
because of exceptional circumstances the PASSENGER AIR BAG
OFF light must come on and stay on, whenever the ignition is

& WARNING (continued)
• 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 arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install the rearward-facing child safety seat
in a rear seating position and have the airbag system inspected by
your authorized Audi dealer. •

How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .

Intelligent t echnology
---------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors=>
page 245. If a not iceab le
slip is detected at the wheels (e.g. on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
Electronic limited slip differential
In vehicles w ith front wheel drive *, an e lectron ic lim ited slip d ifferen­
tial engages when driving on curves . The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. T his m ini­
m izes sliding on the front wheels and enables precise and neutral dr
iv ing t hrouge curves. The electronic lim ited slip differentia l does
no t engage whe n driving in we t cond it io ns or snow.
& WARNING
• Wh en acc elerating on slipp ery s urface s, such a s on ice or snow,
always be careful when depre ssing the accele rator pedal. Even
with the EDL and the electroni c limited slip differential working,
the dr ive wh eels can spin and reduce you r ability to control your
c ar . -Ri sk of cra sh!
• The increased safet y afforded b y EDL and the electronic l imited
slip differ ential d oes not mean th at you can take safety risks .
Alw ay s adapt your d riving st yle to the road c onditions and traffi c
si tuation.
[ i ] Tips
If a fa ult occurs in the ABS, the EDL is also not funct ioning. This is
ind icated by the ABS warn ing light=>
page 15 . •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is a ccelerating.
General notes
T he Anti-Slip Regu lation System (ASR) is in tegrated in the electronic
stabilization program (ESP) . When the veh icle starts up and acceler­
a tes, the wheels are preven ted from sp inning by adjust ing the engine
power to match the amount of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervent ion.
With the a id o f the ABS sensors=>
page 245, ASR moni tors the speed
of the driven wheels. If the wheels start to spin, engine torque is
reduced automatically unti l the tires find enough grip to lock onto
the road s urface. The system is active across the entire speed range . .,

Intelligent technology
--------------------------------------------------' '----'----
Functioning of Anti-Lock Brake System
(ABS}
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents the
w heels from
locking whe n the brakes are applied . This means t hat t he
vehicle rema ins steerable and is less likely to skid.
With ABS you do not need to pump the brake. Ju st hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance under all
circu mstances. When d riving on gr ave l o r on new ly falle n snow o n top
of icy s urfaces, braking distance may be even longer, therefore, under
t he se c ir cu mstances, i t is especially importa nt that you dr ive slowly
and with great care.
How the ABS system works
An a utomat ic check is made when a speed of about 12 mph (20 km/h)
is reached. When this happens, a pumping noise can be heard.
If an individ ual w heel beg ins to rotate too slow ly in relat ion to vehicle
speed and tends to lock, t he ABS automat ic al ly reduces brake pres­
sure to prevent t hat wheel from locking .
Thi s automatic adjustment process w ill cause a
slight vibrat ion of
t he bra ke ped al and some noises to aler t you th at vehicle s peed mus t
be adapted to existing road and traff ic conditions.
& WARNING
Although the ABS is very effective , always remember that braking
capability i s limited by tire traction . Always adjust your driving
speed acco rding to the road and traffic condition s. Do not let the
extra safety afforded by the ABS tempt you into taking extra risk s.
T he ABS cannot overcome the laws of physics .
Controls and equip­ ment Safety first Vehicle operation
(I] Tips
•
If ABS is no t fun ct io ni ng prope rly, a wa rning light will come on .
See =>
page 15.
• If a fault occurs in the A BS, the EDL is also not functioning . This is
indicated by t he ABS warn ing light .•
Brake assist
Brake assist is designed to achieve the optimum braking
effect.
Bra ke ass ist helps to i ncrease the effe ctive br aking power and thus to
achieve a shorte r stopping distance . If the d river presses the brake
peda l very quickly, brake assist automatically boosts the bra king
force to the max imum level, up to the po int whe re the anti-lock b rake
function (ABS) intervenes to stop t he wheels from locki ng . You
should then keep the br ake peda l pressed unti l the veh icle has braked
to the required speed . Brake ass ist switches itself off as soon as you
re le ase the br ake pedal.
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow the vehicle ahead of you too clo sely. Increased ri sk of an
accident cannot be compensated for even by brake assist , so
alway s maintain a safe speed .•
