Child safety
-Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
- Never put the forward-facing child restraint
up, aga inst or very near the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-fac ing child restraint. The backrest
must be adjusted to an upright posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
_&. WARNING
Rearward-fac ing ch ild restra ints:
- 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 inflates -even with an Ad ­
vanced Airbag System .
- T he inflating airbag wil l hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest, door
or roof.
- Always be especially carefu l if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the t ime
whenever the ignition is switched on .
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immed iately in­
stall the rear-fac ing ch ild safety seat in a
rear seating position and have the airbag

· Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint.
Always heed the child safety seat manufacturer's
instructions when installing a child restraint in
your vehicle . T o activate the convert ible locking
retractor:
.. Place the child restraint on a seat, preferably on
the rear seat .
.. Slowly pull the belt
all the way out.
.. Route it around or through the child restraint
belt pat h
c::> ,&..
.. Push the ch ild safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety be lt back into the retractor un­
til the belt lies flat and snug on the ch ild safety
seat.
.. You should hear a "clicking" noise as the belt
w inds back into the inertia reel. Test the con­
vert ible lock ing retractor by pulling on the belt .
You should no longer be able to pull the belt
out of the ret ractor. The convertible locking re­
tractor is now activated .
.. Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly .
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or s ideways more than
one inch (2 .5 cm).
_&. WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.
- Always make sure that the safety belt re­
tractor is loc ked when insta lling a child safe­
ty seat. An unlocked safety belt retractor
cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a chi ld is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

manufacturer's instructions.
"' Depress the spring catch on the hook and re­
lease it from the anchorage.
(D Note
If you leave the child restraint with the tether
strap firmly insta lled for several days, this
could leave a mark on the upholstery on the
seat cush ion and backrest in the area where
the tether strap was installed. The upholstery
wou ld also be permanently stretched around
the tether strap. This applies espec ially to
leather seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems
come with a tether. P lease read and heed the
child restraint system manufacturer's instruc­
tions carefully to determ ine how to properly in­
stall the tether .
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
ser iously injured and can be killed if the front
airbag inflates -even w ith an Advanced A irbag
System.
- T he inflating a irbag w ill hit the chi ld safety
s eat or infant carrie r wi th grea t fo rce and
will smash the chi ld safety seat and chi ld
against t he backrest, center armrest, or
doo r.
- If you mus t install a rearward facing chi ld
safety seat on the front passenger seat be­
cause of exceptional c ircumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install

Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common . All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas ­
oline. For more information on TOP TIER Deter-
"' gent Gasoline, please go to the off icial webs ite

stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
@ Note
- Yo ur vehicle's diesel engine was designed
soley for use with ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These conta in substances
that will severe ly damage the fuel system
and the engine . Such damage will not be
covered by you r New Veh icle Limited War­
ranty.
- If you put any amount of incorrect fuel i n
the fuel tank, do not start the eng ine under

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.
The cooling system is sea led and generally re ­
q ui res lit tle atten tion.
The cooling system has been filled at the factory
w ith a pe rma nen t coolan t which does no t need to
be ch anged . T he coolant consists o f a mixture o f
specia lly condit ioned wa ter and the man ufactu r­
er's glycol -based coolant additive Gl3 antifreeze
with anticor rosion add itives (SO% for USA mod­
e ls · 60% for Canadian models) . Th is m ixture bot h

system from corrosion and scaling . It also raises
t h e boiling point of the coo lant .
D o no t redu ce the con cen tra tion of the coolan t in
the summer by ad ding plain water.
The prop or­
tion of coolant additive mu st be at least 50%
but not more than 60%
to maintai n antifr eeze
protection and cooling efficiency . If the coo lant
frost pro tec tion is too low, the coo lant co uld
freeze and damage the vehicle heating and en­
gine cooling system .
For year- ro und driving, antifreeze is added at the
factory for temperatures down to :
-- 31°F(-3S° C)USA
- -40 °F ( - 40 ° C) C anada.
If you must add coolant, use a mixture of water
and coolant additiv e. Mix ing the coo lant add it ive
with dis tilled wa te r is recommended .
A WARNING
Befo re you c hec k anythi ng i n the engi ne com ­
partment, always re ad and heed a ll WA RN­
IN GS
~page 198.
(D Note
- Befor e wi nter sets in , have the coo la nt
c hecke d to see if the cool an t additive in you r
vehicle is sufficient to meet the climate con ­
ditions . This is espec ia lly impo rtant if you
live in a region where the winter is extreme ­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to yo ur cool ­
ing system, remember:
- We recommend us ing o nly coo la nt addi­
tive G12 ++ o r G13 ( che ck the label) fo r
your ve hicl e. This coolant addi tive is av ail­
a ble at autho rized Aud i dea le rs . Othe r
types of ant ifreeze can significant ly re­
d uce corrosion protection. The resulting
corrosion can ca use a loss o f coolant and
serious engine damage.
- Do not add any type of rad iator leak sealant
to y our vehicle's engine coolant. Adding ra­
diator repa ir fluid may adversely affect the
function and perfo rmance of your cooling .,,.
205

Checking and F ill in g
sure you are using the correct brake f luid .
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir .
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can ser iously affect the effic iency of
the brakes as well as your safety . This
could res ult in an accident.
(D Note
Brake flu id will damage the paint of your vehi­
cle .
@ For the sake of the environment
Because of the problem of proper d isposa l of
brake fluid as well as the spec ia l tools re-
quired and the necessary expertise, we rec ­
ommend tha t you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
The battery in yo ur Audi does not need any ma in­
tenance under normal operating conditions. Aud i
recommends having the electro lyte level check by
an author ized Audi dealer or author ized Audi
Service Fac ility when the re a re
high outside tem­
pe ratu res or when dr iv ing a ll day. The electroly te
leve l sho uld also be checked ea ch t ime the bat ­
t ery is charged
9 page 210 .
Have the battery checked when you br ing you r ve­
hicle in fo r an inspec tio n. It is a good idea to re­
p la ce the batte ry if i t is more than 5 ye ars old .
During certai n types of a irbag dep loyments, the
battery is disconnect ed from the vehicle electr i­
cal system fo r safety reasons
9 .&. in Repair, care
and disposal of the airbags on page 163.
Disconnecting the battery terminals
Some veh icle functions (such as power windows)
are not ava ilable when the batte ry is disco nnect­
ed. These functions must be programmed after
the ba ttery is reconnec ted. To avoid havi ng to do
t his , on ly disconnect the b attery from the veh icle
