_& WARNING
Improper use of tether anchorages or low­
er anchorages can cause serious personal
injury in a crash.
- Always carefully follow the child re­
straint manufacturer's instructions for
proper installation and use of child re­
straint systems.
- Never use the
LATCH or tether anchorag­
es to attach safety belts or other kinds of
occupant restraints.
- Child restraint tether attachments and
lower attachments are only designed to
secure a child restraint that has been
equipped to use these anchorages.
- Tether anchorages and lower anchorages
are designed to withstand only those
loads imposed by correctly fitted child
restraints. Under no circumstances can
they be used safely for adult or child
safety belts or harnesses.
- Never mount more than one child re­
straint to a single tether or to a lower an­
chorage point. Attaching two child re­
straints to a single anchorage point can
cause the anchorage to fail and cause se­
rious personal injury in a crash.
(D Note
-Remove the guidance fixtures before
folding the rear seatback to prevent
damaging the seat cushion.
- If you leave the guidance fixtures instal­
led for several days, they could leave a
mark on the upholstery on the seat cush­
ion and backrest in the area that the
guidance fixtures were installed. The up­
holstery would also be permanently
stretched around the guidance fixtures.
This applies especially to leather seats.
Child Safety 221
Installing a child restra int with LATCH
lower anchorages
Whenever you install a child restraint always
follow the child restraint manufacturer's in­
structions.
Fig. 227 Lower anchorages: proper mounting
Mounting
.. Make sure the seatback of the rear seat
bench is in the upright position and securely
latched in place.
.. Attach both hook-on connectors with the
spring catch release on the child safety seat
onto the LATCH lower anchorage so that the
connectors lock into place
¢fig. 227.
.. Pull on the connector attachments to make
sure they are properly attached to the LATCH
lower anchorage .
.. Pull straps tight following the child re­
straint manufacturer's instructions.
Releasing
.. loosen the tension on the straps following
the child restraint manufacturer's instruc­
tions.
.. Depress the spring catches to release the
anchorage hooks from the lower anchorag­
es.
Remember: Use tether straps to help keep the
child restraint firmly in place.
A WARNING '-
Improper use of the LATCH system can in-
crease the risk of serious personal injury
and death in an accident.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDRs are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Intelligent technology 225
Electronic Stabilization
Control (ESC)
General information
The ESC improves the vehicle stability.
. ..---------..
------- -
Fig. 232 Center console with ESC sw itch
ESC is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especially when accelerat­
ing and cornering. ESC reduces the risk of
skidding and improves stability under all road
condit ions .
The system operates across the entire speed range in combination with the ABS system. If
the Anti-Lock Brake System (ABS) malfunc­
tions, the ESC will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic
Differential Lock (EDL) and the Anti-Slip Regu­
lation System (ASR) are integrated in the Elec­
tronic Stabilization Control. In addition to the
data prov ided by these functions, the ESC con­
trol unit requires additional measurement da­
ta provided by high performance sensors. The
rotational speed of the vehicle about its verti­
cal axis, vehicle acceleration in the fore-and­
aft and lateral directions, the brake pressure and the steering angle are all measured.
T he direction in wh ich the driver wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actual behavior of the ve­
hicle. If the two do not match, for example,
when the vehicle starts hydroplaning on a wet
road, ESC will automatically brake the appro-
priate wheel to correct the problem. ..,_

226 Intellig ent technol ogy
The vehicle is then stabilized by the forces act­
ing on the whee l during braking. If the vehicle
is
oversteering (rear tends to sk id out of the
turn), the brakes are ma inly applied on the
wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering
(tendency to slide out of the curve), the
brakes are applied as needed on the whee l
that is on the ins ide of the curve or addit ional­
l y on the o ther wheels. An acoustic s ignal indi­
cates when ESC b rake app lication cuts in
¢ A .
The system operates across the entire speed
range in combination with the ABS system
¢ page 229. If the Anti-Lock Brake System
(ABS) malfunctions, the ESC wi ll be out of ac­
tion as well .
Activating
When you turn on the engine, ESC w ill auto­
mat ica lly be act ivated and will perform a se lf­
test. As soon as the test is comp leted, the sys­
tem is in normal operating mode.
Offroad mod e
ESC should normally be ope rated in normal
mode because this ensures maximum vehicle
stability. If necessary, you can act ivate the
ESC offroad mode by pressing the but to n
¢ fig . 232 to obtain maximum traction and
braking ability when driving
off paved roads at
l ow speeds. In ESC offroad mode, the indica­
tor light

b ilization control (E S C): Offr oad . Wa rning !
R estric te d stabilit y
appears br iefly in the dis­
p lay .
The ESC offroad mode can be useful in the fo l­
low ing except ional situations when slip or a
h ighly effective differential locking function is
des irable . Examp les:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
whee ls severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck . When the
unusual situation is past, you
sho uld shift back to the norma l ESC operating
mode by pushing the button again . The mes­
sage
S ta b ilizat ion cont rol (ES C): O n then ap­
pears briefly in the display.
H ill desc ent control
The hill descent control is switched on in ESC
offroad mode . When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides ass istance by automatically apply ing the
brakes to keep vehicle speed constant. The ve ­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force. Hill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also axle
art iculation).
Hill descent contro l operates both d riving for­
ward and in reverse. Active hill descent con­
tro l is deactivated by pressing the accelerator
pedal until the condit ions for activation al­
ready listed are met again .
A WARNING
--
- The Electronic Stabilization Contro l is
neverthe less s ubject to the laws of phys­
ics. It is part icularly important to pay at­
tention to this fact on wet and slippe ry
roads . It i s therefore important that you
always adapt your dr iving to the cond i­
tion of the road and traffic conditions . Do
not a llow the increased safety provided
by the E lectronic Stabilization Contro l
system to lull you into accepting addi­
tional safety risks .
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pe ry road, the wheels may have an in­
creased tendency to sp in and the vehicle
may b reak away - dange r of skidding!
~

-Stability is limited in the ESC offroad
mode.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General notes
The electronic differentia l lock (EDL) helps the
car to start movi ng, accelerate and climb a
gradient on surfaces providing poor or almost
no grip. Without EDL, this would be difficult,
if not impossible.
H ow the system works
The ED L opera tes automatically. It monitors
the rotat iona l speed of wheels w ith the help
of the ABS sensors¢
page 229. If a noticea­
b le
slip is detected at the wheels (e .g. on slip ­
pery ground
on one side), the spinning whee ls
are braked and power is transferred to the
other wheels. This is done up to a speed of
about
60 mph (100 km/h) . Noises from the
brake system s ignal that wheel sp in is being
controlled.
Dri ving 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
w ith less gr ip, apply
plenty of throttle until
the car starts to move.
O verheating of br akes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads on this wheel, the EDL cuts out tempo­
rarily . T he vehicle remains operational and be­
haves in the same way as a veh icle w ithout
E DL.
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 carefu l
when depressing the acce le rator pedal.
Int ellig ent technolog y 22 7
Even with the EDL working, the drive
wheels can spin and red uce your ab ility
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your driving style to
the road condit ions and traffic situation .
(D Tips
If a fault occurs in the ABS, the EDL is also
not functioning. This is ind icated by the
ABS warning light¢
page 18.
Anti-Slip Regulation System (ASR )
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regu lation System (ASR) is inte­
grated in the Electronic Stabilization Control
(ESC). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the
amount of grip available from the road sur­
face .
How the sy stem works
ASR performs automat ically, i.e. without the
driver's intervention. With the aid of the ABS
sensors ¢
page 229, ASR monito rs the speed
of the dr iven wheels .
If the wheels start to
spin, engine torque is red uced automat ically
unt il the t ires find enough grip to lock onto
the ro ad surface. The system is active across
the entire speed range.
T he ASR works in conjunction with the ABS. If
a malfunc tion s hou ld occu r in the ABS, the
ASR wi ll also be out of act io n.
A WARNING ~
The increased safety affo rded by ASR does
not mean that you can take safety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation.

-Before descending a steep grade, reduce
speed and shift transmiss ion 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 dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the brakes to
overheat, prema ture wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions 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
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct ­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
sure which is created only when the engine is
running¢ &,.
Int ellig ent technolog y 229
A WARNING
-Never let the veh icle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­
der braking.
T he ABS contributes effect ively to vehicle con­
trol s ince it preve nts the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to skid .
With ABS y ou do not n eed to pump the
bra ke. Just h old t he br ake ped al d own .
However, do not expect the ABS to shorten
braking distance under
all circumstances.
When dr iving on g ravel or on new ly fallen
snow o n top of icy s urfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS s ystem works
An a utomat ic check is made when a speed of
about 12 mph (20 km/h) is reached . When
th is happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rotate too
s low ly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that whee l from locking .
T his automatic adjustment p rocess will cause
a
sli ght vibrati on of the brake pedal and some
noises to a le rt you that ve hicle speed m ust be
adapted to existing road and traffic condi ­
tions. •

8_ WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction . Always adjust your dr iv­
ing spee d according to the road and t raffic
co nditions. Do no t let t he extra sa fety af­
forded by the ABS tempt you into ta king
extra risks. The ABS cannot overcome the
laws of physics.
@ Tips
- If ABS is not functioning prope rly, a
warning light will come on. See
¢page 18 .
-If a fault occurs in the ABS, the EDL is al­
so not functioning. This is indicated by
the ABS warning light .
Brake assistant
The brake assistant is designed to achieve the
optimum braking effect .
The brake assistant helps to increase the ef­
fective b rak ing power and thus to achieve a
shorter stopp ing distance. If the driver
presses the brake pedal very quickly, the brake
assistant automatica lly boosts the braking
force to the maximum level, up to the point where the anti-lock brake function (ABS) inter­
venes to stop the wheels from locking. You
should then keep the brake pedal pressed un­
til the veh icle has braked to the required
speed . The brake assistant sw itches itself off
as soo n as you re lease the brake pedal.
Automatic full braking a ssist
This funct ion allows full brak ing in spite of
h igh brake pedal forces (e .g . when the brakes
a re 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 trave l. When the brake peda l is
r e leased, fu ll braking assis t switc hes off again
automatically.
I f the re is an ABS fa il ur e, the brake ass ista nt
and automatic full b rak ing ass ist are not avai l­
ab le . The brake assistant wi
ll not be operative if
there is a ma lfunction in the ABS .
8_ WARNING
-Please remember that the accident risk a l-
ways increases if you drive too fast, espe­
cially in corners or on a slippery road, or if
you follow the veh icle ahead of you too
closely. Increased r isk of an accident can­
not be compensated for even by the brake
assistant, so always maintain a safe speed.
Servotronic ® -
advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic ® power steering
system senses the road speed and electron i­
cally adjusts power assistance to provide com­
fortab le and safe steering response exact ly
matched to the vehicle speed .
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
The power steering fluid level is checked dur­
ing the scheduled maintenance services .
d) Note
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed .
This is most not iceable when turning the
stee ring wheel at low speeds (fo r example
when pa rking), - more effort w ill be re­
q uired than us ua l.
- Be aware o f the different than usual
steering response and adjust your steer ­
ing force accordingly.
- Have the problem checked and set r ight
by an Audi dealer as soon as possible .

@ Tips
- When the engine is running, never hold
the steer ing whee l turned a ll the way to
the right or t o the left f or longer than 15
seconds. The power steering pump w ill
overheat the hydraulic f lu id if you keep
hol ding the steer ing wheel turned all the
way. This is likely to damage the power
steering system.
- If the power steer ing system should fail
ent irely, or if the engine is not running
(fo r example, while being towed), you
will still be ab le to steer the vehicle.
However,
considerably more effort will
be required to do so.
- If the power s teer ing system should
have a leak, or is not functioning proper­
l y, contact yo ur authorized Audi dealer
immediately.
- The power stee ring system requires a
spec ially formulated hydraulic fluid. The
power steering reservo ir is the one locat­
ed farthest to the rear on the left side of
the engine compartment
c> page 266.
The co rrect flu id level in the reservoir is
i mportant for proper functioning of the
power steer ing .
Driving with your

Winter tires
When driving in the w inter, your ve hicl e w it h
all -wheel drive has an advan tage, even with
regu lar tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea­
son t ires) for improved driveability and brak-
Int ellig ent technolog y 231
ing: these tires must be mounted on all four
wheel s. See also ¢
page 295, Winter tires .
Tire chains
Where tire chains are mandatory o n certain
roads, this no rma lly also app lies to veh icles
with all-wheel drive¢
page 296, Snow
chains.
Replacing wheels /tires
Vehicles with all-wheel drive must always have ti res of t he same s ize. A lso avo id tires
with different t read depths. For det ails see

tires and wheels .
_& WARNING
A lways adj ust yo ur driv ing to road and traf­
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
-Altho ugh the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippe ry road surfaces .
- On wet road surfaces, be careful not to drive too fast because the front wheels
could begin to slide o n top of the water
(aquaplaning). If th is should occur, yo u
will have no warning from a s udden in­
crease in engine speed as w ith a front ­
wheel drive vehicle. Always drive at
speeds which are suited to the road con­
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventiona l energy system
is not driven for a long per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e.g. immobi liz e r). In certa in circumstan ces it ..,_
•
•

232 Intelligent technology
can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en­
e rg y management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regulates consumption, so
that more ele ctrical energy is not being used
than is being generated and ensures an opti­ mal state of cha rge for the battery.
{D) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
c> page 233,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing the cold time
of year . Abundant electrical energy is re ­
quired, but only a little is generated . It is also
critical if the engine is not running and e lectri­
ca l components are turned on . In this in­
stance energy is being consumed but none is
being generated.
It i s in precisely these situations that you will
notice energy management actively regulat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks , e lectr ica l compo­
nents are gradually cut back or sw itched off.
T his reduces energy consumption and main­
ta ins start ing capability over a longer period .
Take into consideration that when you unlock
your vehicle , some conven ience functions ,
s uc h as the inte rior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the e ngine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off or use other MMI func ­
tions, the battery is being discharged .
If starting capability is jeopardized due to en­
ergy consumption , the following warning ap­
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.
