Using tether straps on rearward-facing
child restraints
Curren tly , few rear-facing child res traint sys ­
tems come with a tethe r. P lease re ad an d
heed the child res traint system manufactur­
er's instructions carefully to determine how to
properly insta ll the tethe r.
A WARNING
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates -even with an Ad ­
vanced Airbag System.
- The inflating a irbag w ill hit the child
safety seat or infant carrier w ith g reat
force and w ill smash the ch ild safety seat
and child against the backrest, ce nte r
armrest, or door.
- A tight tether or other st rap on a rear­
wa rd-fa cing child restra int attached to
the fro nt p assenger se at can put too
much pressure on the weight -ma t in the
seat and register a heavier we ight in the
Advanced Airbag System. The heavier
we ight registered can make the system
work as though an ad ult were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing se rious or
ev en fatal injury to the child.
- If you must install a rearward facing child safety seat o n the front passenger
seat because of exceptional circumstan­ ces a nd the
PASSENGER AIR BAG OFF

Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Aud i pre sense can ini tia te steps to help pro­
t ect veh icle occupants in certain situa tions.
The funct ions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
certain driv ing situations :
- Tightening of the safety belts (for examp le,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
s lightly and are ready to be tightened again .
- Closing the w indows and the sunroof* : the
windows and the sunroof* close leaving a
small open gap .
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the dep loy­
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so ca lculated . If the system senses an immi­
nent collision the follow ing functions can be
tr iggered :
-Audi braking guard
c::> page 92
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi p re sense rear includes the functions in
Audi pre sense basic. In addition, the likeli ­
hood of a rear -end collis ion with the vehicle
coming from behind is also calc ulated.
If the risk
of a co llision is detected, the following
functions can be triggered :
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats : the settings for the
power head restrains, the upper sections of
t he backrests and the pneumatic side bol­
s ters* are optim ized for the front seats and
the outboard rea r seats*. If a collision does
not occur, the previo us seat settings are re­
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
A udi pre sense front and Audi pre sense rea r.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
-Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk o f a coll is ion and serio us personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli ­
sion.
- Aud i p re sense does not detect peop le or
animals or objects that are crossing the
vehicle's path
c::> page 86.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from be ing ac­
curately detected and in some cases they
may not be detected at all.

190 Intelligent technology
Intelligent technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs for the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's 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.
A lthough 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, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal 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 ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a control unit. Some of
the data then stored may re late 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.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the engine is running. ESP detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw) out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steer ing assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
liJ in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP cannot overcome the laws of
physics. It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered w ith water,
slush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a ve hicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle unde r con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

214 Cleaning and protection
leathe r, whi ch has a smooth surface and
comes in various co lors .
The intensity of the color determines the v is u ­
a l charac ter istics and appearance. If the sur­
face of the leather has a typical natu ral look,
then the leather is a nappa leather that has been left in a relatively natural cond ition. This
leather offers particularly good comfort and
breathes well. F ine veins, closed grains, insect
b ites, skin folds , and subtle var iations in co lor
remain visible . These c haracteristics demon­
strate that the mater ia l is natural.
Natural nappa leather is not covered by a col­
or fi nish . It is therefore more sensitive to soil ­
i ng and wear, w hich is something you need to
consider if ch ild ren , an ima ls or othe r factors
might prove to be particular ly hard on the
l eathe r.
By contrast, leat her types that are covered by
a co lored finish layer a re mor e durable . This
has a posit ive effect o n the leather's resist­
a nce to wear and soil ing in daily use. On the
o ther hand , the typical characteris tics of na tu­
ra l leather a re barely or not apparent. Howev ­
e r, this does not mean that the leather itself
is of infer ior quality.
Care and handling
Because of the exclusive na ture of the types of
l eather that Audi uses and the ir unique prop­
erties (such as sensitivity to oils, grease, soi l­
ing, etc.), you will need to be somewhat care­
fu l w ith these leathers, and a ce rtain type of
care is required. For examp le, dark clot hing
materials can d iscolor leather sea ts (especial­
ly if such clot hing is damp and was not dyed
correctly) . Dust and d irt part icles in po res,
folds , and seams can have a n ab ras ive effect
and can damage the leathe r sur face as well as
weaken seams.
The leather should be cleaned regula rly as
needed. After havi ng been used for a re lative ly
l ong time, yo ur leather sea ts will acqui re a
ri ch aged finish. This is a charac ter istic of n at­
u ra l lea ther and a sign o f true quality . In order to maintain the val
ue of this nat ural
product over the life of your vehicle, you
sho uld follow the recommendat ions be low :
(D Note
- To keep your leather from b leaching o ut,
do not allow it to be exposed to b right
sunlight for long periods of time . If you
have to leave the ve hicle parked outside
for long per iods, cover the leather to
protect it from direct exposure to sun ­
light .
- Sharp objects on cloth ing, such as zip­
pers, rivets or sharp pieces on belts can
leave permane nt sc ratches or sc rape
ma rks on the su rface of the leather.
(0 Tips
- After each time you clean the leather and
at regular intervals, use a leathe r preser­
vative c reme that contains UV-b locke rs
and tha t works into the leat he r. Thi s
c reme will nour ish a nd moistu rize the
leather, helping it to breathe and stay
supple. It a lso helps to build up a p rotec­
tive coating on the surface.
- Clean the leat her every 2 -3 months,
and clean any a reas that get soi led .
- Remove fresh ma rks made by ballpo int
pe ns, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- P reserve the color o f the leather as need ­
ed by using a specia l co lore d leathe r care
creme to touch up areas of uneven color .
Cleaning and caring for leather
upholstery and trim
Applies to vehicles: with natural leather
Natural lea ther requires special care and at­
tention .
Normal cleaning
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth . .,.

216 Cleaning and protecti on
- To avoid damage, have stubborn stains
removed by a commercial cleaning spe­
cialist.
- Do not use br ushes, stiff sponges or sim­
ilarly abrasive cleaning aids.
Safety belts
Only well-maintained safety belts work relia ­
bly when needed .
> Keep belts clean.
> For cleaning, use a mild soap and wate r sol­
ution . Let be lts dry thoroughly and away
from direct sunlight .
> Do not allow inertia reel safety be lts to re­
tract before they are completely dry.
> Check the condition of your safety belts reg­
ularly .
Heavily soiled safety belts may not retract
properly.
.&_ WARNING
Damaged safety belts can break in a crash.
- Anything that might damage your safety
belts could mean that you and your pas­
sengers would not be adequately pro­
tected in an acc ident.
- Safety belt performance depends on cor­
rect installation. Never remove belts
from the vehicle to clean them.
- Do not use chemical cleani ng agents,
bleach or dyes. They have corrosive prop­
ert ies which weaken the webbi ng.
- When cleani ng your safety belts, inspect
them for damage.
If you discove r dam­
age, see you r A udi dealer.
- Always read and heed all WARNI NGS and
other information

A WARNING
-=
-The cooling system is under pressure and
can get very hot . Reduce the risk of
scald ing from hot coolant by following
these steps .
- Turn
off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glycol in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire. Excess cool­
ant w ill be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze
Q page 229 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while obse rv­
ing all environmental regulations.
Checkin g and fillin g
Radiator fan
The radiator fan switches on automatically by
itself .
The rad iator fan is dr iven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
An auxiliary electric radiator fan* switches on
and
off depending on coolant temperature
and other vehicle operat ing cond it ions .
After you switch the engine
off, the aux iliary
fan can continue running for up to 10 minutes - even with the ignition
off. It can even switch
on again later by itself
Q &., if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coolant reaches a certa in temperature and w ill
continue to ru n until the coolant temper­
ature drops.

246 Tires and wheels
valve stem caps on all wheels are secure ly
mounted on the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded will not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle control, but can also damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
l oad limits are techn ica lly referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory installed accessories, a full
tank of fuel , oil, coo lant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any luggage in the ve­
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weight of the
l oaded trailer must be included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-p illar. You r A udi has 5 seat ing
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Vehicles with pow- er individual rear seats* have
4 seating posi ­
tions,
2 in the front and 2 in the rear for total
seat ing capac ity of
4. Each seating position
has a safety belt¢
page 137, Safety belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle (including the weight of a
trailer hitch and the tongue weight of the
loaded trailer) is lim ited . The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the max imum combined weight of a ll of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label¢
page 242, fig. 184.
A WARNING ,___
Overloading a vehicle can cause loss of ve­
h icl e contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle with in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.
