Economical and environmentally-friendly
driving
The amount of fue l consumption, the e nviron­
men tal impact and the wear to the engine ,
b rakes and ti res depends mostly on your dr iving
s tyle. W it h an anticipatory a nd econom ic dr iv ing
style , fu el consumpt ion can be reduced by ap ­
p roxima te ly 10 -15% . The following tips will help
you conse rve the environment and you r money at
the same time .
Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra ting.
W hen you drive wi th an tic ipa tion, you do not
n eed to brake as often and so yo u ac celerate less .
When possib le, let your vehicle coast w ith a
gear
engaged ,
for example, when you notice that the
next tra ffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt io n to ze ro (fuel shut-off dur ing decelera ­
tion) .
Shift efficiently
An effective way to save f uel is to upshift earlier .
Staying in a gear too long uses fue l unnecessari­
l y .
Press down o n the acce lerator peda l s lowly and
avoid "k ic k -down".
D riving
Avoid full acceleration
Yo u should rarely travel at the maxi mum vehicle
speed. High speeds cause a disproport ionate ly
high increase i n fue l cons umption, emissions and
t raffic noise. S lowe r driving saves fue l.
Reduce idling time
The Sta rt-Stop system* helps to red uce the idling
t ime a utoma tically. In veh icles w ithout the S ta rt­
Stop system *, i t is eff icient to sw itch the engine
off when stopped at railroad crossings and long
r ed lights. Stopping the engine for 30-40 sec­
onds a lready saves more fuel than the amo unt of
extra fue l needed to restart the engine.
It ta kes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase. Therefore, you sho uld begin driving im­
med iate ly after starting the engine. Avoid h igh
RPMs wh ile doing this .
Have maintenance performed regularly
By having maintenance pe rformed regu larly on
your vehicle, you can help to reduce fuel co n­
sumption before you even start to drive. The
maintenance condition of your vehicle not o nly
affects traffic safe ty a nd long-term val ue but al­
so impa cts
fuel consumption . A poorly main­
t ai ned engi ne ca n lead t o fuel co nsump tion that
is 1 0% hig he r th an no rmal.
Avoid short trips
The eng ine and exhaust cleaning system must
r each their optima l
operating temperature to ef­
fec tively reduce consu mption a nd emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reac hes operat ing

Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct press ure
r:!;> page 220. The
fuel consumpt io n can increase by 5% if the pres ­
s ur e is on ly 0 .5 bar too low. Due to t he inc reased
r oll ing resistance, low tire p ressures w ill also .,..

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your
engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine.
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard
your eng ine requi res, you m ay ad d a tot al of
no more than 0.5 q t (0.5
l) of a h igh-quali ty
"synthe tic"oil that meets t he following speci ­
fications.
- Applies to: gasoline engine: ACEA A3 or
API SM with a viscosity g rade of SAE 0W-30,
SAE SW -30 or SAE SW-40.
- Applies to: diesel engine: ACEA C3 or API C F
with a viscosity grade of SAE 0W-30 or
SAE SW-30.

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and cool­
ing of internal engine components, a ll inter nal
202
combust ion engines consume a certa in amo unt
of oil. Oil consumption varies from engine to en­
gine and may change signi ficantly over the life of
the engine. Typically, engines w ith a specified
break-in period (see
c:::;, page 66) consume more
o il dur ing the break-in per iod than they consume
af ter o il consumption has stab ilized .
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revo lutions per m inute) at
wh ich the engine is operated, the amb ient tem­
perature and road condit ions. Furt her facto rs a re
the amo unt of o il di lution from wate r condensa ­
t ion or fue l resid ue an d the oxidation level of the
o il. As any engine is sub je ct to wear as mileage
builds up, the oi l cons umption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumption can be estab ­
li shed or spec ified. The re is no alte rnative to reg­
ul ar and freq uent checking of the oi l level, see
Note .
If the yellow engine oi l level warning symbo l in
the instr ument cluster
El lights up, yo u should
check the o il level as soon as possible
c:::;, page 203. Top off the o il at your ea rliest con­
venience
c:::;, page 203.
A WARNING
Before you check a nyth ing in the e ng ine com­
par tment, always read and heed all WARN­
IN GS
c:::;, .&. in Working in the engin e compart­
ment on page 198.
(D Note
Drivi ng w it h an insuff ic ient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warn ing d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before going
on a long trip .

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much . This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident .
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.

@ For the sake of the environment
Reinstall su mmer tires at the appropriate
time, because they pro vide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
@ Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter tires are required, only
w inter t ires with the
& symbol may be per­
m itted .
Snow chains
Snow chains not only imp rove the dr iving in w in ­
ter ro ad conditions, b ut also the brak ing .
.,. Only install snow chains o n the front wheels .
T his applies also to ve hicles w ith all wheel
drive* .
.,. Check and correct the sea ting of the snow
chains a fter dr iv ing a few fee t, if necessa ry. Fo l­
l ow the instructions from the manufacturer .
.,. Note th e maximum speed of 30 mph (SO km/
h). Note the loca l regulat ions.
Use of snow chains is on ly permitted with certain
rim/t ire combinations due to technical reasons .
Check with an authorized Audi dealer or author ­
i z ed Aud i Service Fac ility to see if you may use
snow chains.
You must remove the snow c hains on roads w it h ­
out snow. Otherw ise, you could impa ir dr iv ing
ab ility and damage the tires.
A WARNING
Us ing incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
cont rol, which inc reases the risk of an acc i­
dent .
(D Note
-Snow cha ins can damage the rims/wheel
covers* if the chains come into d irec t con­
tac t wi th them . Remove the wheel cove rs*
first. Use coa ted snow chai ns.
226
- Us ing snow c hains that add more than 0. 4
inch (10.S mm) of height can severely dam­
age the whee l housings and other vehicle
components .
- Do not insta ll and use snow chains if there is
a malfunction in the adapt ive a ir suspen­
sion*, because the vehicle he ight will be
very low. If you drive wit h snow chains any­
way, the whee l housings and other vehicle
components can be seve rely damaged .
(D Tips
When using snow chains, it may be useful to
switc h on sport mode

Low aspect ratio tires
You r A udi is factory-equ ipped with low aspect ra­
tio t ires . T hese tires have bee n thoroug hly tested
a n d been sele cted specifi ca lly for your mode l for
thei r sup erb pe rformance, road fee l and han dling
u nder a var iety of driving conditions. Ask your au ­
thori zed Audi dea ler for more detai ls .
The low as pec t rat io o f these tires is indica ted by
a n umera l of
55 or le ss in t he t ire's si ze designa ­
tion . The numeral represents the ratio of the
tire's si dewa ll height in relation to its trea d width
expressed in percentage. Conventiona l tires have
a height/width ratio of 60 or more.
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to improper inflation pres­
sure. It is the refore important that low aspect
rat io tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tir e pressur es should
be checked at lea st once a month and always
before a long trip
¢ page 220.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potholes, curbs, gullies or
r idges on the road , particula rly if the tire is un -
der i nfla ted. .,..

Wheels
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
CD General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­ ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
228
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­ ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure tel ltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low t ire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
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 veh icle 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.
