174 Child Safety
• When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertible locking feature on the safety
belt to prevent the child safety seat from
moving
c::;, page 177 or install the seat using
the LATCH attachments .
• Push the child safety seat down with your
full weight to get the safety belt really tight so that the seat cannot move forward or
sideways more than one inch (2.5 cm)
c::;, page 177.
• If the child safety seat is equipped with a
tether strap, attach it to the tether anchors
c::;, page 183.
• Secure unused safety belts on the rear seat
c::;, page 172.
A toddler or child is usually too large for an in­
fant restraint if it is more than one year old
and weighs more than 20 lbs. (9 kg) .
Toddlers and children who are older than one
year up to about 4 years old and weigh more
than 20 lbs (9 kg) up to 40 lbs. (18 kg) must
always be properly restrained in a child safety
seat certified for their size and weight
c::;, fig. 134 and c::;, fig . 135.
The airbag on the passenger side makes the
front seat a poten tially dangerous place for a
child to ride . The front seat is not the safest
place for a child in a forward-facing child safe­
ty seat.
It is a very dangerous place for an in­
fant or a larger child in a rearward-facing seat.
A WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death in a
collision or other emergency situation.
- Children on the front seat of any car,
even with Advanced Airbags, can be seri­
ously injured or even killed when an air­
bag inflates. 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 in-
-
flates -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
arm rest, door or roof .
- Always install rear-facing child safety
seats on the rear seat .
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan ­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
Audi dealer.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat.
- For adjustable head restraints: adjust or
remove the rear seat head restraint if it
is difficult to install the child seat with
the head restraint in place
c::;, page 55. In­
stall the head restraint again immediate­ ly once the child seat is removed. Driving
without head restraints or with head re­ straints that are not properly adjusted
increases the risk of serious or fatal neck
injury dramatically.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
¢page 131, Safety
belts, c::;, page 140, Airbag system
and
c::;, page 166, Important things to know.
A WARNING
-
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe­
ty and well-being require that the follow­
ing special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer for use on a front seat with a passenger front and side airbag.

178 Child Safety
-If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear -facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger airbag inflates.
- 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, door or roof.
- Always install rear-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safety seats or in­
fant carriers installed on the front pas­
senger's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child.
- It is safer to install a forward-facing
child safety seat on the rear seat.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used¢
page 166. Special
precautions apply when installing a child
safety seat on the front passenger seat
¢ page 142, Child restraints on the front
seat -some important things to know .
A WARNING
-
Always take special precautions if you
must install a forward or rearward-facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF
light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described ¢
page 152, Moni­
toring the Advanced Airbag System.
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion .
-An improperly installed child restraint can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child.
-Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- After checking to make sure that the
child restraint is properly installed, make
certain that the child restraint is correct­ ly recognized by the capacitive passenger
detection system in the front passenger
seat and that the
PASSENGER AIR BAG
OFF
light signals the correct front pas­
senger frontal airbag status.
A WARNING
-Forward-facing child restraints:
- Always make sure the forward-facing seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up, against or very near the in­
strument panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the forward-facing child restraint. The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.

194 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
> Always use lead-free gaso line¢ page 206,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
¢ page 215, Adding engine oil > Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- Never touch the exhaust tail pipes once
they have become hot . This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢page 215.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel

Caring and cleaning
General information
Regular, proper care helps to maintain your
vehicle's val ue . It can also be a requirement
when submitting warranty claims for corro­
sion damage and paint defects on the body.
The necessary care products can be obtained
from your a uthorized Audi dea ler . Read and
follow the instructions for use on the packag­
i ng.
A WARNING
- Us ing clean ing and care products incor­
rectly can be dangerous to your hea lth .
- Always store cleaning and care products
out of reach of children to reduce the r isk
of po isoning.
-
@ For the sake of the environment
- Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not d ispose of leftover cleaning and
care products with household trash.
Car washes
T he longer that deposits such as insects, bird
droppings, tree sap or road sa lt rema in on the
veh icle, the more the surface can be dam­
aged . High tempe ratures such as those
caused by sunlight increase the cor rosive ef­
fect .
Before washing, rinse off heavy depos its with
p lenty of water .
Also, was h the underside of your ve hicle once
road salt stops be ing used for the season.
P ressure wash ers
When washing your veh icles w ith a pressure
washer, always fo llow the operating instruc­
tions provided with the pressure washe r. T his
is especially important in regard to the pres ­
sure and spraying d istance. Do not aim the
spray directly at seals on side w indows, doors,
the hood, the rear lid or the sunroof* or at
Caring and cle anin g 201
tires, rubber hoses, insulating material, sen ­
sors * or camera lenses* . Keep a distance of at
l east 16 inches (40 cm).
Do not remove snow and ice with a p ressure
washe r.
Neve r use rotary nozzles or high pressure noz­
z les.
T he wate r temperature must not be above
140
°F (60 °() .
Automatic car washes
Spray off the ve hicle before washing.
Make sure that the windows and roof * are
c losed and the winds hield wipers are off . Fol­
l ow instructions from the car wash operator,
especially if there are accessories attached to
your vehicle.
If possible, use car washes that do not have
brushes .
Washing by hand

working down using a soft sponge or cleaning
brush . Use solvent -free clean ing products.
Washing vehicles with matte finish paint
by hand
T o avoid damaging the paint when washing,
f irst remove dust and large particles from
your vehicle . Insects, grease spots and finger­
prints are best removed with a spec ial cleaner
for matte finish paint .
Apply t he p rod uct using a microfiber cloth . To
avo id damaging the paint surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water . Then
clean using a neutra l shampoo and a soft mi ­
crofiber cloth .
Rinse the ve hicle thoroughly again and le t it

214 Checking and Filling
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods .
Detergent additives in the o il wi ll make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports.
In order to provide effective lubrication and
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible
¢
page 215. Top off the oil at your earliest
convenience
~ page 215.
A WARNING
-~
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 210.
(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.

complexity of today's automobi les, have
steadi ly reduced the scope of maintenanc e
and repairs which can be carried out by vehicle
owners.
Also, safety and env ir onm ental con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even vo id your vehicle war­
ranty. The refo re, p roof of servic ing in accord­
ance w ith the ma intenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
I f in doubt about any servicing , have it done
by your authorized Audi dealer or any other
p roperly equipped and q ualified workshop .
We strong ly urge you to give your aut horized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
Performing limit ed m aintenance you rself
The fo llowing pages describe a limited num­
