same kind of child restrain t offered by child
restraint manufacturers.
T he weight ranges for the ind iv idual types,
makes and models o f ch ild restra ints tha t the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir
bag System. When a child restraint is being
used on the front passenger seat with a typi
cal 1 year-old ch ild, the Advanced Airbag Sys
tem compares the we ight measured by the
weight sens ing mat with the info rmat ion s to r
ed i n the electron ic cont rol unit.
The electron ic control unit a lso registers the
tension on the front passenger safety be lt.
The te nsio n on the safety be lt fo r the front
p assenger seat will be d iffe ren t fo r an ad ult
who is properly using the safety belt as com
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger measures the
tension on the be lt. The input from this sen
sor is then used with the we ight to "decide",
whether there is a ch ild restrai nt with a typ ical
1 year-o ld child on the front passenge r seat
and whether or no t the airbag must be turned
off.
Child restraints and Advanced Airbags
Regard less o f the child res traint that you use,
make sure that it has been ce rtified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu-
facturer for use with an airbag. Always be sure
that the child restraint is properly insta lled at
one of the rea r seat ing pos itions .
If in excep-
tional c ircumstances you must use it on the
fr ont passenge r seat, caref ully read all of the
i n formation on c hild safety and Adv ance d Air-
b ags an d heed a ll of the app licable WAR N-
I NGS . Ma ke certai n that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
fro nt passenger airbag is turned off and that
Child Sa fet y 167
the a irbag s tat us is always cor rect ly signaled
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
have been available over t he years, new mod
els are introduced regu larly incorporating new
and improved designs and o lde r models are
ta ken o ut of product ion . Ch ild restraints are
not standard ized. Child restraints of the same
type typically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they a re insta lled on a vehi
cl e sea t. T hese d iffe rences make i t vir tually
i mpossible to certify compl iance wi th t he re
quiremen ts for advanced airbags with each
and every ch ild restraint that has eve r been
sold in the past or wi ll be sold over the course
of the useful life of your veh icle.
For t his reason, the United S tates Na tional
Hig hway T raffic Safety Administration has

194 Driving and en vironm ent
@ For the sa ke of the environment
Even when the Emission Contro l System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
t he economy of your vehicle, as well as ex
haust and noise levels.
Fue l economy, environmental impact , and
wear on you r engine, bra kes and t ires la rgely
depend on th ree factors:
= yo ur personal dr iv ing sty le
- operating conditions
- technical lim itations
If yo u anticipate what you need to do next and
drive economically, you can easi ly cut your
fue l consumption by 10-15 percent. This sec
tion will give you some t ips on how you ca n
he lp the environmen t and your pocketbook.
(D Tips
The consumpt ion estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not co rre
spond to your actual consumption on the
road, wh ich will vary depending upon vehi
cle load an d speed, road and weather con
ditions, tr ip le ngth, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating .
.,. Avoid unnecessa ry accelerating and braking. Vehicles use the most fuel when they are ac
ce le rating. If you anticipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red .
· Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maxi-
m um speed .
Acce lerat ing gently red uces fue l cons ump
tion, engine wear, and does not disturb the
environment.
F uel consumpt ion, exhaust emissions a nd en
gine noise inc rease disproportionate ly at high
speeds . If yo u drive at approximately th ree
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weathe r con
ditions pe rm it.
Reducing unnecessary idling
Even when your car is jus t idling it burns up
fuel.
.. Shut the eng ine off when you are not driv
ing the vehicle .
.. Do not warm up the vehicle by letti ng the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail
r oad crossings, or at traffic lig hts that have
long wai ts on red . Tu rn ing the eng ine off for
j ust 30-40 seconds saves more fuel tha n is

It takes a long t ime for the engine to warm up
fully when it is ru nning at id le. However, wea r

218 Check ing and filling
Modern engine lubrication has taken a quan
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu
brication that can outlast traditional petrole
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 to he lp keep your vehicle's engine
running smoothly and help prevent the for
mat ion of harmfu l deposits, sometimes called
"sludge ", that ove r time can lead to expensive
repairs .
At the time of print ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifications of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every synthetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de
posits use only oi l with the fo llowing specifi
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica
tion s ingly or in comb inat ion with other des ig
nations and oil qua lity standards .
Visco sity
Engine oils are graded accord ing to their vis
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
SW40 is not available, you can also use viscos
ity grade SAE SW -30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart (
li ter) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is at or be low the
minimum mark -and no oi l that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top
off
with a high quality engine o il, preferab ly syn
thet ic-based, tha t mee ts ACEA A3 or API SM
specifications, but even then , only in v iscosity
grades SAE SW-40 , SAE SW-30, or SAE
OW-40. However, dur ing the entire time be
tween oil change inte rva ls , never top
off with
more than a total of 0.5 q t/ liter engine o il
t h at does not con form to Audi oi l specification
vw 502 00.
For more informa tion about eng ine oi l that
has been approved for your veh icle, please
contact e ither your authorized Aud i dealer or
Audi C ustomer Re lations at 1 (800) 822 -2834
or visit our web site at www .audiusa.com or
www.aud icanada .ca. Here you w ill also find a
current list of oils (manufacturers, brand
names e tc.) tha t conform to Audi oil s tanda rd
vw 502 00 .
Changing the engine oil
The eng ine oi l and oil fi lter must be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs .
Changi ng the oil at the recommended inter
vals is so very important because the lubricat ing proper ties of oil decrease gradually during
normal veh icle use . If you are not sure when
you have your oil changed, ask your author ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
should even be changed more frequent ly .
Change oil more often if you drive mostly
short distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
ditions, o r when you use your vehi cle where .,..

222 Check ing and filling
Engine 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 sealed and generally re
quires little attention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-basedcoolant additive G 13 antifreeze with
anticorrosion add itives (SO% for USA mode ls;
60% for Canadian models). This mixture both
assures the necessary frost protection and protects metal components in the engine's
cooling system from corrosion and scaling. It
a lso raises the boiling point of the coolant .
Do not reduce the concentration of the coo l
ant in the summer by adding plain water .
The
p ro po rti on of c ool ant add it iv e mu st b e at
lea st 50 % but not mo re th an 60%
to main
tain antifree ze protection and cooling efficien
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
_& WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
¢ &. in Working in the engine
compartment on page 215.
(]) Note
-
- Before winter sets in, have the coolant
checked to see if the coo lant additive in
your vehicle is s uffic ient to meet the cli
mate cond it ions . Th is is especially impor
tant if you live in a region where the w in
ter is extremely cold . If necessary, in- crease the p
roportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing on ly coolant ad
d itive G12++ or G13 for your veh icle .
This coolant additive is availab le at au
thor ized Audi dealers. Other types of
ant ifreeze can s ignificantly reduce cor
rosion pro tection. The resulting cor ro
sion can cause a loss o f coolant and se
rious engine damage.
- Do not add any type of rad iator leak seal
ant to yo ur vehicle's engine coolant .
Adding radiator repair fl uid may adverse
ly affect the function and performance of
your cooling system and cou ld resu lt in

sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this norma lly also applies to
veh icles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model
<=> page 274.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 24 7
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k
shop.
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi
tions . Ask your authorized Aud i dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 236, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
