• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an authorized Audi
dealer as soon as possible.
• If a steering malfunction occurs, this is signaled with the or.
~ indicator lights and a warning tone, see.
[ i] Tips
• If the power steering system should fail, or if the engine is not
running (for example, while being towed} , you will still be able to
steer the vehicle. However, more effort will be required to do so.
• If the power steering system is not functioning properly, contact
your authorized Audi dealer immediately.
Ap plies to vehicles : w ith A ll Wheel Drive
0 iving w i h your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=> page
184, "Electronic differ
ential lock (EDU".
Winter tires
When driving in the winter , your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-season tires} for improved
driveability and braking : these tires must be mounted on all four
wheels. See also=> page 250, "Winter tires".
Controls and equip ment Safety first Vehicle operation
Intelligent technology
Snow
chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=> page 251, "Snow
chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page => page 246, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=> page 192.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua planing}.
If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle . Always drive at speeds which are suited to the road condi
tions. -risk of crash. •

conditi ons permit. •
Reducing unnecessary Idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the eng ine run at
idle.
I t makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at railroad crossings, or at traffic lights that have long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle . However, wear and noxious emissions a re especial ly
high when the engine is warming up . So you should drive away as
soon as you start the engine and avoid running at high RPMs whi le
the engine is stil l warming up .
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idl ing also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .•
Regular maintenance
A badly tuned en gine unnecessarily wastes a lot of fuel.
- Have your v ehicl e serv ice d at reg ular intervals.

By having your vehicle regularly serviced by an Audi dea ler helps to
ensure that i t runs properly and economically . The conditio n of your
vehic le not only affects its safety and abi lity to hold its va lue, it also
affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load and speed .
I t is normal for the oi l consumption of a new eng ine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometres) be fore you can proper ly assess o il consumpt ion.
This also applies to fuel consumption and engine output .

washed in specia l wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high -p ressure
power washer is safe as l ong as y ou observe a few simple
rules .
-Before using the power washer, make s ure you have read
and understood the WAR NINGS=::;,
& in "General infor
mati on" o n
page 198.
-Always follow the operating instructions for the power
washer. - Make sure that the jet o
n the spray hose pro duces a "fan
sha ped sp ray".
D o
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particula rly to the
operating
pre ssure
and the spraying di stance . Maintain a sufficient distance
to soft materia ls such as rubber hoses and sound/vibration dead
ening materia ls (part icularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should not exceed 140 °F (60 °Cl.
& WARNING
Never wash tire s with a jet that sp ra ys water in a dir e ct stream .
Thi s could cau se invisible damage to the tire s and we ake n them ,
eve n if th e spra y is from a re lativel y lo ng dis tanc e an d f or a sh o rt

a nd per sona l injur y.
0 Note
To avoid damaging your vehicle, always make sure that there is
suffic ient distance between the spray head and soft materia ls like
rubber hoses, plastic parts and sound -deadening materials . Never
aim the spray head at the same p oint for a long time . This also
applies to cleaning headlights and painted bumpers . Remember :
the c loser the nozzle is to the surface of the material, the greater the
stress on the mater ial. •

Engine oil consumption
The engine in your vehicle depends on an adequate
am ount of oil to lubricate and c ool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ificantly over the life of the engine . Typically,
engines with a specified break-in period (see~
page 190) consume
more oil during the break-in period than they co nsume after o il
consumption has stabilized .
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fue l residue and the oxidation level of the oil. As
any engine is subject to wear as mileage bu ilds up, the oil consump
tion may increase over time until rep lacement of worn components
may become necessary .
With all these variables coming into play, no standa rd rate of oil
consumption can be estab lished or specified. There is no a lternative
t o regula r and frequent checking of the oil level, see Note.
I f the yellow engine oil level warning symbol in the instrument
cluster _ lights up, y ou should check t he oi l level as soon as
possible
with the oil dipstick~ page 221. Top off the oil at your
earl iest co nvenience ~
page 222.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
~ & in "Working in the engine
c ompartment " on
page 217 .
0 Note
Driving with an insuff ic ie n t o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pressure w arning display ce,. is not an indi cator of the oil
level . Do not rely on it. Instead, check the oil level in your engine at
regular interv als , prefe rably ea ch time you refuel , and always before
going on a long trip.
• I f you have the impression your engine consumes excessive
amoun ts of oi l, we recommend tha t you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measureme nt of oil consumption requires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil consumption accurately. •

Battery
General information
Your vehicle is equipped with a specia l battery, an AGM battery. This
ba ttery is loca ted in the luggage compar tment and must be
replaced with an original equipment battery. Under normal oper
ating conditions, the battery is
ma inten anc e-free .
Have the battery checked when you take your vehicle in for service .
You a re well advised to replace a battery that is o lder than 5 years .
Disconn ecting th e batt ery te rmin als
Some vehicle functions (power w indow regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected again. To prevent this, the battery should only be disconnected from the
vehic le electrical sys tem when abso lutely necessary for repairs .
Vehi cles not dri ven for lo ng p eriods
If you are going to let your vehic le stand for a long time and n ot
drive it, you should remember there are e lectrica l components
whic h are still functioning and they will draw energy from the
battery and drain it, for example, the engine immobilizer. To prevent
t his, you can eithe r charge the batte ry occasionally to keep it in
good working condition or you can disconnect the negative cable
on the battery.
W int er op erati on
During the winter months, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le starting, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling o nly short distances . Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 232. A we ll charged battery will not only preven t starting
problems when the weather is cold, but will also last longer.
Repla cing batter y
The new battery must hav e the same capacity, voltage ( 12 volts),
amperage, construction and p lug sea ling, as the orig inal battery .
Specifications are listed on the battery housing. Batteries specia lly
developed by Aud i fulfill the main tenance, output, and safe ty
requirements. ...,
