Child sa fety
Advanced front airbag system and children
Your veh icle is equipped w ith a front "Advanced
A irbag System" in comp liance w it h United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your veh icle has
been certified to meet the " low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the a irbag inflates. In addit ion, the
system has been certified to comply w ith the
" su ppress io n" req uirements of the Safety S tand­
ard, to tu rn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven tho ugh yo ur vehicle is equipped with an
Ad a
vanced Airbag system, a chi ld should a lways ride
in the seat proper ly restrained for its age and
size. The airbag on the passenger side makes the
front seat a potentially dangerous p lace for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dange rous place for a n infant or a
larger child in a rearward-fac ing seat.
The vehicle's Advanced Airbag System has a ca­
pac itive passenger detect ion system in the front
passenger seat cush ion that ca n detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on t his seat .
The capac it ive passenger detect ion system regis ­
ters the changes that result in an electr ical field
when a c hild, a child restra int, and a baby blanket
a re on the front passenge r seat. The change in
t he meas ured capacitance due to t he p resence o f
a child, a chi ld restraint, and a baby b lanket on
the front passenger seat is re lated to the chi ld
restraint system resting on the seat . The meas ­
ured capacitance of a ch ild restraint system var-
218
ies depending on the type of system and specific
make and mode l.
The elect rical capac ita nce of the va rious types,
makes, and models of child restra in ts speci fied
by the U.S . National Highway Tra ffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
c hi ld restraint is used on the front passenger
seat w it h a typical 1 year-old infant, t he Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detect ion
system wi th the data stored in the e lec tronic co n­
tro l unit .
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
factu rer for use w ith an airbag . If in exceptional
c ir cumstances you m ust use it on the front pas­
senger seat, ca refully read all of the information
o n chi ld safety and Advanced Airbags and heed
a ll of th e app licab le WARNINGS . Make certain
that the chi ld and chi ld restraint are correctly
recognized by the capacitive passenger detection
system in the front passenger seat, that the front passenger a irbag is turned off, and that the air­
bag status is always correct ly signa led by the
PASSENGER AIR BAG OFF ~; light.
Many types and models of child restra ints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production . Ch ild rest rai nts are not standa rdized .
Child res tra ints of the same type typically have
d iffe rent weights and sizes and diffe re nt "foot ­
pr ints", the size and shape o f th e bo ttom of the
ch ild restraint that sits on the seat, w hen they
are installed on a vehicle seat . These differences
make it virtua lly impossib le to certify comp liance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .

Chec king and Filling
the engine . Con tact an authorized A udi
dealer or authorized Audi Service Facility to
have excess eng ine oil extracted if necessa­
ry.
@ Tips
The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operat ing condi­
tions. Consumption may be hig her during the
first 3,000 m iles (5,000 km) . Because of th is,
the engine o il level must be checked reg ular­
l y .
It is best to check each time you refuel
your vehicle and befo re long drives.
- In order to prov ide effec tive lubrication and
cooling of internal engine components, a ll
internal combustion engines consume acer­
tain amount of oil. Oil consumption var ies
from engine to engine and may change sig­ nificantly over the life of the engine . Typi­
cally, eng ines with a specified break-in peri­
od consume more oil during the break-in pe­
r iod than they consume after oil consump­
tion has stabilized .
- Under normal condit ions, the rate of oil
consumption depends on the quality and
viscos ity of the oil, the RPM (revolutions per
m in ute) at which the engine is operated, the
ambient temperatu re and road conditions .
Further factors a re t he amo unt of oi l di lu­
t ion 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
time until replacement of worn components may become necessary.
- With all these var iables coming into play,
no standard rate of o il consumption can be
established or specified. There is no alterna­
t ive to check ing the oil leve l regularly and
frequently.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult a n author ized Audi
dea le r to have the cause of your conc ern
properly diagnosed. Keep in mind tha t the
acc ura te measurement of o il cons umption
requires great care and may take some

tions about how to measure oil consump ­
tion acc urately.

lubricating properties of oil diminish gradually
during normal vehicle use.
Unde r some c ircu mstances the eng ine o il should
be changed more frequently . Change oil mo re of­
ten if you drive most ly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have your vehi­
cle where temperatures remain below free zing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
A ud i de ale r or
a qualified service station .
If you c hoo se to change your o il y our self , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection .
- To reduce the risk of burns from hot engine oil, let the eng ine cool down to the touch.
-
- When removing the o il drain plug with your
fingers, stay as far away as poss ible. A lways
keep your forearm paralle l to the ground to
help prevent hot o il from runn ing down your
arm .
- Drai n the oil into a container designed for
this pu rpose, one large enough to hold at
least the total amount of oil in your e ng ine .
- Engine oil is poisonous . Keep it well out of
the reach of ch ild ren .
- Cont inuous contact w ith used eng ine oi l is
harmful to your sk in. A lways protect your

mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
