& WARNING
Improper installation of child restraints will increase the risk of
injury and death in a crash.
• Always follow the instructions provided by the manufacturer
of the child restraint you intend to install in your Audi.
• Improper use of child restraint anchors (including tether
anchor s) can lead to injury in a collision. The anchors are designed
& WARNING (co ntinued )
to withstand only those loads imposed by correctly fitted child
restraint s.
• Never mount two child restraint systems on one LATCH lower
anchor po int .
• 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
belts or other kinds of occupant restraints.
• Never secure or attach any luggage or other items to the LATCH
lower anchorages or to the tether anchors .
• If a tether or other strap is used to attach a child restraint to
the front passenger seat, make sure that it is not so tight, that it
causes the weight-sensing mat to measure more weight than is
actually on the seat .
• The heavier weight registered can make the Advanced Airbag
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.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
i mmediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer. •

- Loosen the tension following the child restraint manufac
turer's instructions.
- Depress the spring catch on the hook and release it from
the anchorage.
0 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
cush ion and backrest in the area where the tether strap was installed.
Th e upholstery would also be permanent ly 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 w ith a tether.
Please read and heed the child rest raint system manufacturer's
instructions carefully to determine how to properly install the tether.
& 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. ,-

Electronic differential lock (EDL}
The ele ctr onic dif ferential lock mo nit ors the rot ational
s p eed of the d rive wheels .
General notes
The elec tron ic differe ntia l lock ( EDL) helps the ca r to sta rt movin g,
acce le ra te and climb a gradient on surfaces provid ing poor or almost
no grip. Without E DL, this would be difficult, if not impossible.
How the system works
Th e E DL operates au tomatically . It mo nitors the rotational s peed of
t he drive wheels on an axle with the he lp of the ABS sensors
~ page 19 2. If a noticeable difference in rotational speed between ..
Vehicle care Do-it-yourself service Technical data
Intelligent technologyL ______________________________________ _
the drive wheels on one axle is detected (e.g . on slippery ground on
one side),
the spinning wheel is braked, thereby transferring power to
the other drive wheel or wheels (all -wheel drive) . This is done up to a
speed of about 60 mph (100 km/h). Noises from the brake system
signal that wheel sp in is being controlled .
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface with
less grip, gradually increase the pressure on the accelerator pedal
until the car starts to move. The wheel less ab le to transfer power
spms .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operat ional and behaves in the same way as a vehicle
without EDL .
As soon as the brake has cooled down, EDL switch es on again auto
matically.
Electronic limited slip differential*
In vehicles w ith front wheel drive*, an electronic lim ited slip differen
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. This mini
m izes sliding on the front wheels and enables precise and neutral
driving through curves. The electronic limited slip differential does
not engage when d riving in wet conditions or snow.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL and the ele ctronic limited slip differential working,
the drive wheels can spin and reduce your ability to control your
ca r. -Risk of crash!
& WARNING (continued)
• The increased safety afforded by EDL and the electronic limited
slip differential does not mean that you can take safety risks .
Always adapt your driving style to the road conditions and traffic
situation.
[I) Tips
If a fau lt occurs in the ABS, the EDL is also not f unct ioni ng. This is
indicated by the ABS warning light=>
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabili zation program (ESP) . When the vehicle starts up and acceler
ates, the wheels are prevented from sp inning by adjust ing the engine
power to match the amount of grip available from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the speed
of the driven wheels. If the wheels start to spin, the engine torque is
reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range.
The ASR works in conjunction with the ABS. If a malfunction shou ld
occur in the ABS, the ASR w ill also be out of action .
[I) Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can .,

& 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 trans
mission 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.

'-----------------------------------------------
& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Carefully apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .

Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .
However, do no t expect that the ABS shortens bra king d istance under
all circumstances . When dr iv ing on grave l or on newly falle n snow on
top of icy s urfaces, braking d istance may be even longer, therefo re,
under these circumstances, it is especially important that yo u drive
slowly and with g re at c are.
How the ABS system works
An au tomatic c hec k is made when a speed of about 4 mp h (6 km/ h) is
reached. When t his happens, a pump ing noise can be heard.
If an ind ivi dual wheel begi ns to rot ate too s low ly in relat ion to ve hicle
speed and tends to loc k, t he ABS automatically reduces brake pres
s ur e to p revent t hat wheel from lo cking.
T hi s au tomatic adjustment p rocess w ill cause a
s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving ...

speed acco rding to the road and traffic conditions. Do not let the
e xtra safety afforded by th e ABS tempt you into taking extra risk s.
The ABS cannot overcome the laws of physics .
[ i J Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 16 .
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind ic at ed by t he A BS w arni ng light. •
Brake assistant
The broke assistant is designed to achieve the optimum
br oking effect.
Th e b rake ass istant he lps to inc rease t he effective brak ing powe r and
thus to ac hieve a shorter stopping distance.
If the driver presses the
bra ke ped al ve ry qu ickly, the b rake assistant au toma tically bo osts the
brak ing force to the max imum level, up to the point where the anti
lo ck brak e function (ABS) in tervenes to stop the whee ls from l ocking.
You should then keep the brake pedal pressed unti l the vehicle has
bra ke d to t he require d spee d. T he bra ke ass istan t swi tches itse lf off
as soon as you re lease the b rake pedal.
Th e brake assistant will not be operative if there is a ma lfu nctio n in

& 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 th e vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so always
