Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servici ng or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a co llision.
There are some important th ings you have to
know to make sure that the effect iveness of
the system will not be impa ired and that dis­
carded components do not cause injury or po l­
lute the env ironment.
_& WARNING
Improper ca re, servicing and repair proce­
dures can increase the risk of personal in ­
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpected ly:
- Never cover, obstr uct, o r change the
steering wheel horn pad or airbag cover
or the instrument pane l or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners co uld damage the airbag cover
o r change the stiffness or strength of the
material so tha t the airbag cannot de­
ploy and protec t prope rly.
- Never repa ir, adjust, or change any par ts
of the airb ag sys tem.
- All wo rk on the stee ring wheel, inst ru­
ment pane l, front seats or electrical sys­
tem (incl uding t he inst allation of aud io
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
A irbag system 197
-For any work on the airbag system, we
strongly recommend that yo u see your
author ized Audi dealer or qualif ied work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
-Always make sure that the s ide a irbag
can inflate without interference:
- Never install seat covers or rep lace­
ment upholstery over the fron t seat­
backs tha t have not been specifically
approved by Audi.
- Never use addi tional seat cushions that
cover the areas where the side a irbags
i nflate.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side ai r­
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Aud i
deale r or qualified technician who has
the technical information, training and
specia l equipment necessary .
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
men t pa rts designed and approved espe­
cially fo r you r A udi model version. Re­
placemen t of complete airbag systems
or airbag components mus t be per ­
formed by qualified workshops on ly .
Make sure that any airbag serv ice action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alte rnator and starter are sepa rated
from the veh icle battery with a pyrotech­
nic circuit inte rrupte r.
- W ork on the pyrotechnic c ircuit inter ­
rupter m ust only be pe rformed by a
qualified dea le r - risk of an accident!
- If the vehicle or the circuit interr upter
is scrapped, all applicable safety pre­
cautions must be fo llowed.

206 Child Saf ety
seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re­
straints and for the d ifferent models of the
same kind of child restraint offered by child
restraint manufacturers .
The weight ranges for the individual types, makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced A ir­
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi ­
cal 1 yea r-old chi ld, the Advanced Airbag Sys­
tem compares the weight measured by the
weight sensing mat with the information stor­
ed in the electronic contro l unit.
The electron ic cont rol unit a lso registers the
tension on the front passenger safety belt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com­
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the be lt . T he input from this sen­
sor is then used with the we ight to "dec ide",
whe ther there is a ch ild restraint w ith a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use w ith an airbag . Always be sure
that the ch ild restraint is p roperly insta lled at
one of the rear seat ing pos itions . If in excep­
tional c ircu mstances you must use it on the
front passenger seat, carefu lly read all of the
info rmation on c hild safety and Advanced Air­
bags and heed a ll of the applicable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weig ht-sensing mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is a lways correct ly signa led
by the
PAS SENGER AIR BAG OFF light.
Many types and models of child restraints
have been available over the years, new mod­
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bo ttom of the ch ild restra int that sits
o n the seat, when they are inst alled on a vehi­
cle seat. These d ifferences make it v irtually
impossible to certify compliance with the re ­
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Administrat ion has
published a list of spec ific type, makes and
models of child restraints that mus t be used
to certify comp liance of the Advanced Airbag
System i n your veh icle w ith the suppression

234 Driving and en vironm ent
,8. WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especia lly true for vehicles with low­
slung chassis (sports chassis)* and fully load­
ed vehicles.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer . They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, maintenance and storage. Pay attention to additional information con ­
cerning the battery. Refer to
c::> page 268.
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 tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec­
tion will give you some tips on how you can help the environment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION 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 ore ac­
celerating.
., Avo id unnecessary accelerating and brak ing.
Vehicles use the most fuel when they are ac ­
celerating . If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traffic 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.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the environment.
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.

Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
offroad mode can be activated
c:::> page 224.
Hill descent control is a lso ava ilable in the off ­
road mode, which automat ically brakes the
ve hicl e and thereby keeps speed consta nt
when differe nt w heel speeds a re detected
when descending a hill
c:::> page 226. Your A ud i
a lso has permanent a ll-wheel drive in addi­
tion.
H oweve r, your Aud i is not a pure off road ve hi­
cle . It was not built for d riving unde r extreme
conditions, e.g. for trips that are in the nat ure
of an expedition .
Drive only on road s and offro ad sections
which match the de sign of y our vehicl e and
you r abilitie s as a dri ver. Ne ver t ake ri sks!
Before driving offroad
- Check the eng ine oi l level, t ire pressu re ,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items a nd other objects in the
l uggage compartment, and sec ure t hem
against s lid ing aro und .
After driving offroad
- After trips off road, remove any twigs and
othe r foreign objects from the grill , the un­
derbody and the wheels. Pay spec ia l atten­
t ion to fore ign ob jects (stones) which have
become lodged in t he tire tre ad.
- Clean t he body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty w indows , headlamp lenses, rear
li gh ts, and license plates .
- Perfo rm a brake check (particularly after
t ravell ing throug h water) .
Driving off road 237
A WARNING
-Drive especially attentively and plan
ahead in diff icu lt road conditions and
when off road. Excessive speed o r inco r­
rect maneuve rs can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
e r condition s. D rive e spe cially slowly off­
road when yo ur view is restricted.
- Please be aware that in offroad mode,
pa rti cularly on a smoo th and s lippery
road, the whee ls may have an increased
tendency to spin and the vehicle may
break away -danger of skidding!
- Stability is limited in the offroad mode .

240 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 159, Towing a trailer.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems. From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
c:::> A .
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear v is ion to the rear .
A WARNING ,-
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in yo ur vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches. The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any c ircumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
-
Warranty. Exceeding the Gross Vehicle ~

chains, make sure they wi ll not drag on the
road when you are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
0 Note
If you are going to tow a tra ile r, you must
activa te the trailer operation mode
~ page 159, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
cor e and consid eration.
To obta in the best poss ible handling of vehicle
and tra ile r, p le ase no te the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be especia lly careful when pass ing othe r
vehicles .
.. Observe speed limits.
.. Do not driv e at the maximum p ermissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight di stributio n
Towing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of los ing
steering control.
A "balanced" rig is eas ier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances. Whenever possi­
b le, transfer some cargo to the luggage com­
pa rtment of the tow veh icle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed . Re- duce your speed even more i
f load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
t ry to stop the swa ying by acceleratin g.
Observe speed limits. In some a reas, speeds
f or vehicles tow ing tra ile rs are lower than for
r egular vehicles.
Always apply brakes early. When driving down hill, shift into a lowe r gear to use the en­
gine braking effect to s low the vehicle . U se o f
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coo lant tempe ratu re gauge ~ page 10
must be observed caref ully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warn ing light in
the instr ume nt cluster starts flashing., pull
off the road , stop and let the engine
idle for
about two min utes to prevent heat build -up .
A WARNING "--
Anyone not proper ly restrained in a mov-
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
p rov ided by A udi .
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform­
ance and economy will great ly depend on how
ca refully you load your tra iler and operate
yo ur rig .
Before you act ua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep pract ic ing unt il you

recommended.
A WARNING
Stop! Before working in the engine com­
partment, a lways read and heed all WARN­
INGS
c> .&. in Working in the engine com­
partment on page 257. The engine com­
partment of any motor veh icle is a poten­
tially dangerous a rea and can cause ser i­
ous personal injury.
A WARNING
If you must change the engine oil in your
vehicle:
- Always wea r eye p rotection.
- T o reduce the r isk of burns from hot en-
gine oil let the engine cool down to the
touch.
- When removing the oil drai n plug with
yo ur finge rs, stay as far away as possible.
Always keep your forea rm pa ra ll el t o the
ground to he lp prevent hot oil from run­
ning down your arm.
- Dr ain the o il into a container designed
for this p urpose, one large enough to
hold at least the total amount of oil in
yo ur engine .
- T o reduce the r is k of po ison ing, never use
empty food or beverage containers that
might mis lead someone into drinking
from them.
- Engine oil is poisono us. Keep it well out
of the reach of children.
- Cont inuo us contact with used engine oil
is harmful to your skin . Always protect
yo ur sk in by washing thoro ughly with
soap and water.
@ Note
Never mix oil ad ditives with your engine
oil. These additives can damage your en­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.
(® For the sake of the environment
- Before changing the oil, first make sure
you know where you can prope rly dispose
of the old o il.
- Always dispose of used oil p roperly. Nev­
er dump it on garden soil, in wooded
areas, into streams or down sewage
dra ins.
- Recycle used o il by tak ing it to a used en­
gine oil collection facility in your area, or
contact a se rvice station.
- We strongly recommend that yo u have
your oil cha nged by an authorized Audi
dealer or a qualified workshop with the
special tools a nd expert ise required, and
prope r m eans of disposal.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter.
T he cooling sys tem is sealed and genera lly re­
quires little attention.
T he coo lin g sys tem has been fi lled a t the fac­
tory with a permanent coolan t which does not
need to be changed . The coo lant cons ists of a
mixture of specially conditioned water and the
manufacture r's g lycol-basedcoo lant add i-
t ive
Gl3 antifreeze with anticorrosion addi­
t ives (SO% for USA models; 60% for Canadian
models). This mixture both assures the neces­
sa ry frost protection and protects metal com ­
ponents in the eng ine's cooling system from
corros io n and scaling.
It also ra ises the bo il­
i ng po in t of the coolan t.
Do not reduce the concentration of the cool ­
ant in the summer by addi ng p lain water .
The
proportion of coolant additiv e must be at
lea st 50 % but not more than 60°/o
to main ­
t ai n ant ifree ze pro te ct io n and cooling eff ic ien­
cy .
If the coo lant fros t protec tion is too low '
t h e coo lant co uld freeze and damage the vehi-
cle heating and engine cooling system. ..,.

268 Check ing and filling
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on
<::> page 19 and
<::> page 32. Do not continue to operate the ve­
h icle . The complete brake system should be
thoroughly checked by an authorized Aud i
dea ler or qualified workshop and the cause
corrected. If the brake fluid level is too low,
the brake warning/indicator light will illum i­
nate . Contact an authorized Aud i dealer
im­
m ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh , corrosion in the brake system may result
after a per iod of t ime. The bo iling po int of the
brake fluid wi ll also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y tw o year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id reservo ir can be difficult to
reach, therefore, we recommend that yo u
have the brake f luid changed by you r author­
ized
Audi dea ler. Your dea ler has the correct
too ls, the right brake fluid and the know -how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only i n the closed orig inal container
o ut of the reach of children!
- Brake fa ilure can result from old or inap­
propriate b rake fluid. Observe these pre­
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid . The correct type of
brake f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cau se a vapo r lock if
the b rake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. This co uld resu lt in an accident.
(D Note
Bra ke fluid will damage the paint of you r
vehicle .
(® For the sake of the environment
Because of the p rob lem of p roper disposal
of b ra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
re commend that yo u have the brake fluid
changed by yo ur authorized Aud i dea ler.
Battery
General information
U nder normal ope rat ing cond itions, the bat­
tery in yo ur Audi does not need any ma inte­
nance. With
high o utside tempe ra tur es or
l ong dai ly drives we recommend that you have

wall.
The correct tire pressure for the spare wheel is
located on a label on the driver's side 8-p illar .
Because technical changes may be made to
vehicle equipment dur ing the model year, al­
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size info rmation on the vehicle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
l ongs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of yo ur pas­
sengers also depends on making s ure that load
limits are not exceeded . Veh icle load in­
cludes everybody and eve ryth ing in and on the
vehicle. These load limits are techn ica lly refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle We ight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two ax les.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side 8-pillar . The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the veh icle can carry . For the
location of the tire pressure label¢
