vide supplemental protection in certain frontal
collisions.
.,&. WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situation. To help reduce the risk of se­
rious personal injury and/or death:
- The shoulder belt must lie as close to the
center 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 must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary .
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
¢ page 245.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restraint in place
¢page 62. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Never let a child put the shoulder belt under
the arm or behind the back, because it could
cause severe injuries in a crash.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates .
- Never let a child stand or kneel on any seat,
for example the front seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
288
any way during an accident can be struck by
a deploying airbag. This will result in serious
personal injury or death .
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the
PASSENGER AIR BAG

Securing child seats
· Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts for the rear seats and for the
front passenger 's seat have a convertible locking
retractor for child safety seats . The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size .

loose child safety seat can fly around d uring
a sudden stop or in a collision .
- Always ma ke sure that the rear seat bac k­
rest to wh ich the center rea r safety be lt is
attached is secure ly latched whenever the
rear center safety belt is being used to se­
cure a ch ild rest raint.
- If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will
strike parts of the vehicle interior. The ch ild
can be seriously injured or killed.
- Never install rear-facing child safety seats or infant carriers on the front passenger
seat. A child will be serious ly injured and
can be killed when the passenger airbag in ­
flates .
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and ch ild
against the backrest, center armrest, door
o r roof.
- Always install rear-faci ng child safety seats
o r infant carriers on the rear seat.
- Forward-fac ing ch ild safety seats or infant
c a rriers ins talled on the front passenge r's

· 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 restrain t in
your vehicle . To activate the convertible 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 path
~ ,&. .
.. Push the child 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 belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat.
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to putt the belt
out of the retractor. 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 sideways more than
one inch (2 .5 cm) .
A 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 locked when installing a child
safety seat. An unlocked safety belt retrac­
tor 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 child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

To avoid fuel spill ing or evaporating from the fuel
tank always close fuel cap p roperly and com­
p letely . An improperly closed fue l filler cap may
a lso cause the MIL lamp¢
page 25 to come on .
A WARNING -
Not paying attention when fueling or han ­
dling fue l incorrectly can lead to fires, exp lo ­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when fu ­
eling and/or do not insert the fuel nozz le
completely into the tank opening, fue l can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do not use the telephone whi le fueling. The
electromagnetic rays can cause sparks,
wh ich can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling. If
you must make an except ion and enter your
vehicle again wh ile fueling , close the door
and touch meta l to discharge static electric­
ity befo re touching the fue l nozzle . Static
elect ricity can create spar ks, wh ich can ig ­
nite vapors when fue ling.
- Do not smoke or have an open flame in the
area when fueling your veh icle or filling a
fuel contai ner because th is increases the
risk of an explosion .
- For yo ur safety , carrying f uel containers in
yo ur vehicle is no t recommended. Whethe r
f ull or empty, the conta iner can leak and
cause a fire in the event of an accident .
- If you must make an exception and trans­
port a fuel container, note the following :
- Never fill the fuel container with fuel
while it is in or on the vehicle. Stat ic elec ­
tr icity is d ischa rged when filling wh ich can
cause the f uel vapors to ignite and in­
creases the r isk of an explos ion.
- Always p lace a fuel container on the
g ro u nd before fi llin g.
Ch eck ing and Filling
-Always hold the fuel nozzle completely in
the fuel container when filling .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents stat ic electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Follow lega l requirements when using,
stor ing and transporti ng fuel containers .
- Make sure the fuel container conforms to
industry standards (ANSI/AS TM F8S2 -86).
@ Note
- Remove spilled fuel from vehicle pa int im­
mediately, because it can damage paint.
- Never drive until the fuel tank is complete ly
empty. The irregular supply of fue l that re­
sults from that can cause eng ine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter .
- If the fuel tank runs complete ly empty in a
vehicle with a diesel engine , the ignition
must remain switched on fo r at least 30
seconds afte r ref ueli ng before starting the
eng ine. It may take longer than usual fo r
t he engine to s tart, even up to a minu te .
T his is because the air must first b leed out
of the fue l system when starting the eng in e.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(D Tips
D iesel ve hicles are eq uipped w ith a diesel mis­
fueling guard .
It allows the vehi cle to be fu­
eled on ly with a diesel fuel pump nozzle. A
worn or damaged nozzle or a nozzle that is
too small may not be able to open the diese l
misfueling guard. If this is the case, try turn­
i ng the nozzle before inserting it in the fue l
filler tube, use a different fuel p ump or see an

General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve­ hicle. The Ad B lue usage accounts for approxi­
mately 1.0% to 2.5% of the diesel fuel that is
used.
When a message about refi lling the AdBlue ap­
pears in the instrument cluster display, you must
ref ill the Ad B lue yourself or have it refilled by an

dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consumpt ion
r equi res great ca re and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
.. Park you r vehicle on a level surface.
.. Shut the engine off when it is warm.
.. Switch only the ignition back on.

indicato r is near "min "¢
page 308 .
The engine oil consumpt ion may be up to
0 .5 quart pe r 600 miles (0.5 l iter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be highe r d uring the
fi rst 3 ,000 mi les (5,000 km). Because of this, the
engine o il level must be checked regu larly. I t
wou ld be best to check each time you refuel your

when the engine is runn ing, because this is
a fire hazard .
- Always clean sk in thoroughly if it comes into
contact with eng ine oil.

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,

Changing brake fluid
Hove the broke fluid changed by on experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will also decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
every
two years .
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS

significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-infla­
tion also reduces fue l eff ic iency and tire tread
life, and may affect the vehicle's hand ling and
stopping ab ility.
Please note that the TPMS is not a substitute for
proper tire ma intenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat io n of the TPMS low tire p res­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approxi­
mate ly one m inute and then remain cont inuo usly
illum inated. This sequence will continue upon
subseq uent ve hicle start -ups as long as the ma l­
function exists.
When t he mal funct io n ind icator is ill umin ated,
the system may not be ab le to detec t or signal
l ow tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, incl uding the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensu re
that the replacement or alte rnate ti res and
wheels a llow the TPMS to con tinue to func tion
p roperly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function.
Using the ABS sensors, the tire pressure mo nitor ­
ing system compa res the tire tread circ umfe r­
ence an d vib ration cha racteristics of the individ u­
a l tires. If the pressure changes in one or more
tires, this is ind icated in the instrument cluster
d isp lay with an
RE indicator light and a message.

If only one tire is affected, the location of that
t ir e will be indicated.
