jure each other in an accident .
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and can be killed when the passenger airbag in­
flates - even with an Advanced Airbag Sys­
tem .
- 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.
- Make sure there is enough space in front of
the child in the child seat. If necessary, ad­
just the angle and position of the seat in
front of the child seat.
- Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child. Always install for­
ward-facing child safety seats on the rear
seat.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require that the following
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 pas­
senger front and side airbag.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat to the highest position in the up and down
adjustment range and move it back to the 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 .
- Always make sure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child re-

erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from being moved to the rearmost position in its fore
and aft adjustment range.
- Always make sure that the backrest is in the upright position.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er 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
otherwise added to the front passenger seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for child seats). These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision .

(UJ) Note
The engine oil leve l mus t not be unde r the

(D Tips
The o il level indica tor in the disp lay is on ly an

low, a minimum oi l warning appears in the in ­
strument cluster. Add oil and close the hood.
The current oil level is d isplayed in the Info­
tainment system the next t ime the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.S liter/1,000 km), de­
pending on driving style and operating condi­
tions. In RS models, the o il consumption may
be up to 1 qt/600 mi (0 .8 l/ 1,000 km). Con­
sumpt io n may be h igher du ring the first
3,00 0 miles (5, 000 km). Be cause of this, the
eng ine o il level must be checked reg ularly. It
Ch eck ing and F illing
is best to check each time you refue l yo ur ve ­
hicle and before long drives.
- In order to p rov ide effective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oi l consumption var ies
from engine to engine and may change sig­ nifica ntly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more o il du ring the break-in pe­
r iod than they consume afte r oil cons ump­
tion has stabilized.
- Under norma l condit ions, the rate of oil
c ons umption depends on the q ual ity and
vis cos ity of the oil, the R PM (revo lutions per
m in ute) a t which the engine is operated, the
ambient temperature and road conditions .
Furt her factors are the amount of oi l di lu­
tion from water condensat ion or fue l resi ­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
- With all these var iables com ing into play,
no sta ndard rate of o il consumption can be
established o r specified. There is no a lter na­
ti ve to c hec king the oil leve l reg ula rly and
frequently.
- If you have the impress ion your engine co n­
sumes excessive amo unts of o il, we recom ­
mend that yo u consult an author ized A udi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that the
accurate measurement of o il consumption
requires great care and may take some
time. An authorized Aud i dealer has instruc­
tions about how to measure o il consump­
tion accurately.

when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k

Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

Checking and Filling
(D Note
If the vehicle will be parked for long periods
of t ime , protect it against the co ld so that it
will not be destroyed by "freezing"

Vehicle battery
The term "vehicle battery " refers to the 12 Volt
bat tery in your vehicle.
Not running the vehicle for long pe riods of
t ime
If you do not drive your vehicle for several days o r
weeks , electri cal equipment is gr adually scaled
back or switched off . This reduces energy use and
ensures the veh icle w ill be able to start after long
periods of time
c::> page 126 . Some conve nience
functions, s uch as interior lighting or power seat
adj ustment, may not be available under certa in
circumstances. These convenience f unct ions w ill
be ava ilab le aga in once you switch the ignition on
and start the engine .
E ven w hen electrica l equ ipme nt is swi tched off,
the equipment can still d rain the vehicle battery
if the vehicle is not driven for long periods of
time . Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery .
The vehicle battery must be charged every month
t o reduce the risk of this happening
c::> page 202.
Contact an author ized Audi dealer or authorized
Aud i Serv ice Facility for more information .
Winter operati on
Cold weather places higher demands on the vehi­
cle battery. This results in reduced start ing abili ­
ty . Have the vehicle battery checked by an au­
thor ized Audi dealer or authorized Audi Service
Facility before the co ld time of year .
