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
~- 9 in . (57 inches/1 .45 meters) tall.
Fig. 129 Passe nger seat : ch ild p rop erly rest ra in ed in a
boos ter sea t
Booster seats raise these children up so that
the safety belt will pass properly over the
stronge r parts of their bodies and the safety
belt can he lp pro tec t 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.
• Always position the shoulder portion of the
safety belt midway over the chi ld's shoulder . Child Safety 143
• Always make sure that the shou lder portion
of the safety belt never rests against or
across the child's neck.
• Always make sure that the ch ild can properly
we ar the lap portion of the belt low across
the th ighs or pelvis and
never over the
stomach or abdomen .
It is usually best to put these children in ap­
propr iate booster seats . Be sure the booster
seat meets all applicable safety standards .
Booster seats raise the seating position of the
child and repo sition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the right places . The
routing of the belt over the child's body is very
im portant for the child's protect ion, whether
or not a booster seat is used.
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 restra in any child, regard­
less of how big the chi ld is. A lways 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
poss ible around the pelvis. Never let the lap
belt portion of the safety be lt 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 th e occupant
as the occupan t moves forwa rd into the air­
bag .
A vehi cle occupant who is out of position and
too close to the airbag gets in the way of an
inflating airbag. When an occupa nt i s too
close, he or she will be struck violently and
will receive serious or possibly even fatal in -
jury.

144 Child Safety
In o rder for the airbag to offer protection, it is
important that all vehicle occupants, especia l­
l y any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
a irbag as poss ible. By keep ing room between
the child's body and the front of the passen­
ger compartment, the airbag can inflate com­
p letely and provide supplemen tal p rotection
i n cer tain frontal co llisions .
& WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrect ly installing a
booste r seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or ot her emergency situation. To help re­
duce the risk of ser ious personal injury
and/or death:
- Always make sure to position the should­
er port ion of the three-po int belt over
the midd le of ch ild's shou lder .
- Never let the shoulder port ion of the belt
rest against or across the neck, face,
chin, or throat of the child .
-Always make sure the lap belt portion of the three-po int be lt is worn snug and
passes as low as possib le across the
c hild's pelvis. Neve r let the belt pass over
the soft abdomen.
- Failure to properly route safe ty belts
over a ch ild 's body will cause severe inju­
ries in an acc iden t or other emergency
sit uation
c;, page 10 7.
- Children on t he front seat of any car ,
even w ith Advanced A irbags, can be seri ­
o usly injured or even killed when an air­
bag inflates .
- Never let a child stand or knee l on any
seat, for examp le the front seat.
- Never let a child ride in the ca rgo a rea of
yo ur vehicle.
- Always remember that a ch ild lean ing
f orward, sitting sideways or o ut o f posi ­
t ion in any way during an acc ident can be
struck by a deploying airbag. This will re­
sult in serious personal injury or death.

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the front passenger can be
locked with the convertible locking retractor
to properly secure child safety seats .
The safety belts emergency locking retractors
for the front passenger's seat safety belt have
a convertible locking retractor for ch ild re­
stra ints . The safety be lt must be locked so
that be lt webbing cannot unree l. The retrac­
tor can be act ivated to lock the safety belt and
prevent the safety be lt webb ing from loosen­
ing up during norma l driving. A child safety
seat can only be properly insta lled when the
safety belt is locked so that the chi ld and child
safety seat will stay in place.
Always remember : Even tho ugh your vehicle is
equipped with an Advanced Airbag system, a
ll-

child should always ride in the seat properly
restrained for its age and size .
A WARNING
Improperly installed child safety seats in­
crease the risk of ser ious personal injury
and death in a collision.
- Always make sure that the safety belt re­ tractor is locked when installing a ch ild
safety seat . An unlocked safety belt re­
tractor cannot hold the child safety seat
in place during normal driving or in a
crash.

A WARNING
- The limits of physics cannot be suspend­ed by ESP. Even in vehicles w ith ESP, you
should always adapt your driving to road
and traffic conditions. This is particular ly
t rue on a slippery and wet road. Do not
be tempted by the inc reased safety pro­
vided to take ris ks - danger of an acci­
dent!
- Please note tha t when ESP/ASR is deacti ­
vated, the drive whee ls can spin on icy
and slippery roads and the veh icle can
break away - danger of skidding!

a) Tips
- If Aud i magnetic ride* is malfunct io ni ng,
the ESP may not sw itch off or it may
switch off automatically.

Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels.
General notes
The electronic d ifferential lock (EDL) helps the
ca r to start moving, accele rate and climb a
gradient on su rfaces provid ing poor or a lmost
no g rip. Withou t EDL, this would be d iff icul t ,
i f not impossib le.
How the system works
The EDL operates automatica lly. It mon itors
the rotational speed of the dr ive wheels on an
axle with the help of the ABS sensors
c;:> page 153. If a noticeable difference in ro­
tational speed
between the drive wheels on
o ne axle is detected (e.g. on s lippery ground
on one side), the s pinning wheel is braked,
thereby t ransferring power to the other drive
whee l or wheels (a ll-wheel drive). This is done
up to a speed of about 60 mph (100 km/h). ..,_

150 Intelligent te chn olog y
Noises from the b rake system signal that
wheel spin is being controlled.
Driving off
When drivi ng off, a lways be sure to keep road
conditions in mind as you accelerate. If one
d rive wheel spi ns because it is on a surface
with less grip, gradua lly increase the press ure
on the accelerator pedal until the car starts to
move. The wheel less able to transfer power
spins.
O verheating of bra kes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads, the EDL cuts out temporarily. The vehi­
cle rema ins operationa l and behaves in the
same way as a vehicle without EDL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the acce lerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce yo ur ability
to contro l your car. -Risk of crash!
- The increased safety afforded by EDL
does not mean that you can ta ke safety
risks. Always adapt your dr iving sty le to
the road conditions and traff ic situa tion.
@ Tips
If a fa ult occurs in the ABS, the EDL is also
not f unct ion ing. This is indicated by the
ABS warning light ¢
page 17.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning wh en the car is
accelerating.
General notes
The Anti-Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
(ESP). When th e vehicle starts up and acceler- ates, the whee
ls are prevented from spinning
by adjusting the engine power to match the
amount of grip available from the road sur­
face.
How the system works
ASR pe rforms a utomat ica lly, i.e . w ithout t he
driver's intervention. With the aid of the ABS
sensors ¢
page 153, ASR monitors t he speed
of the dr iven whee ls . If the whee ls start to
spin, the engine torq ue is reduced automati­
cally until the tires find enough gr ip to lock
onto the road surface . The system is active
across the ent ire speed range .
The ASR works in conjunction with the ABS. If
a malfunction should occur in the ABS, the
ASR w ill also be out of act io n.
@ Tips
To ensure that the ASR works properly, all
four whee ls must be fitted wit h ident ica l
tires . Any differences in ro lling radius of
the tires can cause the system to reduce
engine power wh en this is not desired. See
a lso

Automatic mod e (normal operat ion)
- Automatic deployment: At a speed of about
75 mph (120 km/h), the rear spoiler deploys
automatically .
- Automatic retraction: When speed drops be­
low abo ut SO mph (80 km/h), the rear spoil­
er retracts automatically.
Manual mode
- Manua l dep loyment: Tapping briefly on the

Braking
General information
What affects braking efficiency?
Ope rating condition s and driving h abits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve ­
hicles that a re either dr iven mostly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be chec ked by yo ur author­
ized Audi dea ler mo re often than specified in
the
W arranty & Maintenanc e boo klet. Failure
to have your brake pads inspected can result in reduced brake performance .
On steep slopes, you should use the braking
effect o f 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 cont in uous ly. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, braking force and o utside condi­
tions such as temperature and humid ity.
Moisture o r ro ad s alt
U nder certa in conditions, for examp le, when
driving through water or very heavy rain , or
even after washing your vehicle, the b raking
effect can be reduced due to moist ure (or in
freezing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and t he brakes are not used. L ikewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap-
plications of the b rake ¢ .&, .

Anti-lock brake system (ABS)
ABS prevents the wheels from locking under braking.
The anti-lock brake system (ABS) makes a ma­
jor contribution to increasing active dr iving
safety. You should not expect that braking d is ­
tances will be
shortened under all circumstan­
ces with ABS. Braki ng d istance may even be­
come somewhat
longer, for example, on grav­
e l or in new snow on slippery g round, even if
you are driving care fully and s low ly.
ABS operation
When a vehicle speed of about 10 mph (20
km/h) is reached, an automatic test sequence
is run. Some noise from the pump may be au­
d ible.
I f the speed of a wheel slows down too much
r e lative to veh icle speed and it starts to lock,
brake pressure to this wheel is reduced. This
ad justment process can be felt as a
pul sin g
moti on of the br ake pedal , accompanied by
some noises. You as the driver are intentiona l­
ly being given the information that the whee ls
are tending to lock (ABS control range). In or ­
der for ABS to be able to operate optimally in
this range, you must keep the brake pedal de­ pressed - do not "pump the brakes ".
Brake a ssist ant
The brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only w hen the eng ine is run­
ning .
Automatic full br ak ing
This function allows full brak ing in spite of
high brake pedal forces (e.g. when the brakes
are severely stressed because the vehicle is
fully loaded) . The driver notices th is function
throug h a reduction of pedal force and in ­
creased pedal travel. When the brake pedal is released, fu ll braking assist switches off again
automatically .
Intellig ent technolog y 153
If there is an ABS failure, the b rake assistant
and automatic fu ll braking assist are not avail­
able.
A WARNING
- ABS cannot suspend the laws of physics.
You should keep th is in mind in particu­
lar on an icy or wet road . If ABS control
of braking intervenes, you should adjust
your speed immed iately to road and traf­
fic conditions. Do not be tempted by the increased safety provided to take risks -
danger o f an accident .
- Please keep in mind tha t the risk of an
accident is increased by driving too fast,
particularly in bends and on icy or wet
roads, and by driving too close to the ve­
hicle ahead . The increased risk of an acci­
dent cannot be reduced by the brake as­
sistant - danger of an accident.
(D Tips
If a malfunction occurs in the ABS, this is
s ignalled by an indicator light, see
<=:> page 17.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed.
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort .
Power steering will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis­
tance.

156 Intelligent technology
If starting capability is jeopa rdized due to en­
ergy consumption, a message appears in the
driver information disp lay.
You have to start the engine to charge the
battery.
With the engine running
A lthough electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens most ly when
little energy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased slightly . This is normal and not
a cause for concern . By increas ing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, th is
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge : battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig­
nition is turned on or whi le driving and it goes
out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notif ication appears after the ig­
nition is turned on or while driving and does
not go out again, the battery 's state of charge
is not in the optimal range. Starting ability is
restricted . Have the battery checked as soon
as possible by an autho rized Aud i dea le r o r
qualified wo rkshop.

- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 159
fuel consumption by 10 -15 percent. This sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as publishe d
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.
