Child safety
_& WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly install ing a
child restra int increases the risk of serious
personal injury and death in a crash.
- Never install rear-facing child safety seats or infant carr iers on the front passenger
seat -
even with an Advanced Airbag System.
A chi ld will be seriously injured and can be
k illed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, door or roof
c> page 144, Child restraints on the front
seat -some important things to know.
-Always install rear-facing child safety seats
or infant carr iers on the rear seat.
- Never install a rear-facing child restraint in
the forward-facing direction. Such restraints are designed for the special needs of infants
and
very small children and cannot protect
them properly if the seat is forward-facing.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be­ cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
the rear-fa cing ch ild safety seat in a rear
seating position and have the airbag systetn inspected by your Audi dealer.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any ch ild restraint system on
this seat .
- Make sure that there are no wet objects
(such as a wet towel) and no water or other
liquids on the front passenge r seat cushion .
- Never place objects on the seat (such as a
laptop, CD player, elect ronic games dev ice,
power inverter or seat heater for child
seats). These may influence the e lectr ica l

capacitance measured by the capacitive pas­
senger detect ion system and can also fly
around in an accident and cause serious per­
sonal injury .
- Always read and heed all WARNINGS when­
ever us ing a child restrained in a vehicle is
being used.:.>

Convertible child safety seats
Properly used convertible child safety seats can
help protect toddlers and children over age one
who weigh between 20 and 40 lbs. (9 and 18 kg)
in a crash .

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) .
T oddlers and children who are o lder 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 ch ild safety seat cert ified
for the ir s ize and weight <=>
fig. 147 and
¢ fig. 148 .
The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to
ride . The front seat is not the safest place for a
child in a fo rward-facing child safety seat. It is a
ve ry dangero us p lace for an infant or a larger
chi ld in a rearward-facing seat.
_.6 WARNING
-Not using a ch ild safety seat, using the wrong
child safety seat or improper ly installing a
child restraint increases the risk of serious
personal injury and death in a collis ion or oth­
er emergency situation.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inf lates.
A ch ild 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 Ad­
vanced Airbag System.
- T he inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and chi ld
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 fac ing ch ild
safety seat on the front passenger seat be-
Ch ild safety
cause of exceptional circumstances and the
PASS ENGER AIR BA G OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your Audi dealer.
- The rear side of the ch ild safety seat should
be positioned as close as possible to the
backrest on the veh icle seat.
- For adjustable head restraints: adjust or re­
move the rear seat head rest raint if it is dif­
ficult to insta ll the ch ild seat with the head
restraint in place¢
page 55. Install the
head res traint again immed iate ly once the
child seat is removed. Driving witho ut head
restraints or with head restraints that are
not properly ad justed increases the r isk of
serious or fatal neck injury dramatically.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
be ing used ¢

erwise added to the front passenger seat,
never install any ch ild rest raint system on
t h is seat.
- Make s ure that the re a re no wet objects
(s uch as a wet towe l) and no water or other
liquids o n the front passenger seat cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games dev ice,
power inverter or se at heater for child
seats) . These may influence the e lectrica l
capacitance measured by the capacitive pas­
senger detection system and can also fly
around in an accident and cause serious per­
sonal injury.
- Make sure that the

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and 80
lbs. (18 kg and 36 kg) who are less than 4
ft. 9
in . (57 inches/1.45 meters) tall.
Fi g. 1 49 Rear seat: ch ild prope rly restra ined in a booster
seat
The vehicle's safety belts a lone w ill not fit most
ch ild ren until they are at leas t 4 ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs. (36 kg) . Booste r seats raise these ch ildren up so
that the sa fety belt will pass p roper ly over the
stronger parts of their bodies and the safety be lt
can help protect them in a crash.
.,. Do not use the convertib le locking re trac tor
when using the veh icle's safety be lt to restrain
a child on a booster seat.
.,. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck . The
lap belt m ust lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and sn ug. Pu ll on the be lt to tight­
en if necessary.
.,. Secure unused safety belts on the rear seat
c>page 171.
Children up to at least 8 years o ld (over 40 lbs or
18 kg) a re best protected in child safety seats de­
signed for their age and weight . Experts say that
the skeletal structure, part icu larly the pelvis, of
these ch ildren is not fully developed, and they
must not use the vehicle safety belts without a
su itable child restraint.

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high qual ity eng ine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives into the engine oil. Doing so can cause en­

your engine requires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the following speci­

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 65) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase over
ti me unt il replacement of wo rn compo nents may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
