er intervals, move the switch @ to the left/right.
In vehicles with a rain sensor *, the wipers turn on
in the rain once the vehicle speed exceeds ap­
proximate ly 2 mph (4 km/h). The higher the sen­
sitivity of the rain sensor that is set (switch ® to
the right), the earlier the windshield w ipers react
to mo isture on the windshield .
@-Slow wiping
@-Fast wiping
©-Sing le w ipe. If yo u hold the leve r in this posi­
tion longer, t he wipers sw itch from s low w iping
to fast wiping.
® -Clean the windshield . The wipe rs wipe one
time afte r several seconds of dr iv ing to remove
water drop lets . You can swi tch this func tion off
by moving the lever to position ® within 10 sec­
onds of the afterwipe . The afterwipe function is

®-Wipe the rear w indow. The rear w iper moves
about every 6 seco nds.
0 -Clean the rear window . The number of wipes
depends on how long the lever is held in pos it ion
(i) .
& WARNING
-The rain sensor is on ly intended to ass is t th e
driver . The driver may still be responsible
for manually switch ing the wipers on based
on visibility conditions .
- Th e windsh ield may not be treated with wa­
ter-repelling windshield coating agents . Un­
favorable conditions, such as wetness, dark­
ness or low sun, can result in i ncreased
glare, which increases the risk of an acci­
dent. Wiper blade chatter is also possible.
- Properly functioning windshield wiper
blades are required for a clea r view and safe
driving
~ page 39, Replacing windshield
wiper blades .
(D Note
-If there is frost, make sure the windshield
wiper blades are not frozen to the wind­
shield . Swi tching on the w indshield w ipers
when the b lades are frozen to the win d­
shield can damage the w iper blades.
- Th e windsh ie ld w iper system must be
switche d off (lever in posi tion
@ ) before us­
ing a ca r wash. This prevents the w ipers
from swit ching o n uni ntent iona lly an d caus­
ing damage to the winds hield wiper sys tem .
{I) Tips
- The wind shie ld w ipers sw itch off when the
ign ition is swi tched off. You can activa te t he
w indshield wipe rs a fter the ignition is
switched back on by moving the windshield
wiper lever to any position.
- Worn or dirty windshie ld wiper blades resu lt
in streaking . This can affect the rain sensor*
function. Check your windshield wiper blades regula rly. ..,.

braking effec t, which he lps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during dece lera­
tion) .
Shift effici en tly
Upshift ing earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari ­
ly.
P ress down o n the acce le ra tor peda l slowly and
avoid " kick -down ".
Avoid full acceleration
You should rare ly trave l at the maximum vehicle
speed. High speeds cause a d isproportionately
h igh inc rease in fuel consump tion, emissions and
tr affic no ise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopp ing the engine, for ex ­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engi ne for
30 -40 seconds already saves mo re fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to wa rm the en­
g ine up to ope ra ting tempe ra tu re. Wea r and
emissions are especially high in the wa rm -up
phase . Therefore, yo u should begi n driving im ­
mediately after starting the engine. Avoid high
RP Ms while doing t his .
Have maintenance performed r egularly
By having m ainten ance perfo rmed regu larly on
your ve hicle, yo u can he lp to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-te rm value but a l­
so impacts
fuel consumpt ion . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check th e
oil level when refueling . T he oil
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af ­
ter a certain amount of use. Therefo re, the oil
consumpt ion can o nly be properly judged after
58
approximately 3,0 00 miles (S,000 km) have been
driven .
Avoid short trips
The eng ine and exhaust clean ing system mus t
r each their optima l
operating temperature to ef­
fe ct ively reduce consump tion and emissions.
A cold engine uses a d isp roportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption no rmal izes on ly
a fter approximate ly 2.5 m iles (4 km) .
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct pressure ~
page 175. The
fuel consumpt ion can increase by 5% if the p res ­
s ur e is on ly 0.5 bar too low. Due to the i ncreased
rol ling resis tance, low tire p ressures w ill also
l ead to greater tire
wear and will affect driving
behavior .
Do no t drive on
winter tir es ye ar-r ound, as this
will consume up to 10% more f uel.
Eliminate unnecessary weight
S ince every po und of ext ra weight increases fuel
consump tion , a quick inspect io n of the luggage
compartmen t may be wo rth it to avoid unneces ­
s ar y we ight.
When not be ing used, a roof rack shou ld be re­
moved to decrease the w ind resistance of the ve­
hi cle. This will save yo u ap prox imately 1 2% fue l
at speeds from 62 -75 mph (100 -12 0 km/h).
Save energy
The eng ine drives the generator, which generates
e lectric ity; the fuel consumpt io n also increases
with t he demand for e lectricity . T he refore, sw itch

After driving offroad
- After dr iving offroad, remove branches and
other debr is from the radiator gr ille, unde r­
body, and whee ls. Look espec ially for foreign
objects (such as stones) that may be stuck in
the tire tread.
- Clean the vehicle body and underbody and in ­
spect the vehicle for possib le damage.
- Clean the windows, headlights, tail lig hts and
the license plate if they are dirty.
- Perfo rm a brake test (especially after dr iv ing
through water).
A WARNING
- Be especia lly aware and attent ive when driv­
ing under difficult conditions. Vehicle dam­
age and injuries may occur when driv ing at
excessively high speeds or with incorrect
dr iv ing maneuvers .
- Always adjust your speed and driving style
to the roads, terra in , traffic and weather
condit ions. Drive espec ially slowly if there is
low v is ibility when offroad .
- Please note that the wheels can spin more
and the vehicle can swerve when i n ESC off ­
road mode, especially when the road is slip­
pery or has loose surface mate rial.
- Driving stability is reduced in the ESC Off­
road mode .

Driving information
Applies to: vehicles with offroad mode
T here is only one right way to drive in difficult
conditions: slo wly and with caution!
Observe the following when driving on unpaved
roads :
.,. On ly driv e in terrain that is suitable for the ve­
hicle and your driving ability. Never take any
unnecessary risks!
.,. Dr ive slowly and caut iously!
.,. Pay attent ion to the
g round cl earan ce of your
veh icle . The clearance may va ry depending on
the load, ground compos ition and the environ­
ment. The g round clearance is reduced for spe­
cial suspension systems, such as sport s uspen­
sion. The dr iver is therefore responsible for de ­
ciding whether a vehicle can handle a specif ic
situation .
.,. Activate the
ESC offroad mode as needed
r=>page90 .
.,. Use the hill de sce nt ass ist when driving down
steep hills
r=> page 91 .
Difficult terrain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps , etc .) .
T o prevent th e vehicl e from bottoming out and to
reduce the risk of underbody damage, you should
drive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneven area, instead of driving across the cente r of the uneven area with all four wheels .
Drive quickly through sandy or marshy off-ro ad
sections and do not stop, if at all possible.

Automatic transmission
Introduction
The automatic transmission is controlled elec­
troni cally. Upshifting a nd downshifting o ccu r au -
tomat ically . ..,.

Trailer towing
If the tongue we ight is too low, this affects the
trai ler's handling. For driving safety, we recom­
mend to always utilize the maximum permitted
tongue we ight, but not exceed it. Yo u can reach
it, for example, by d istributing the cargo in the
tra iler cor rectly .
You can determ ine the tongue we ight, for exam­
p le, with a bathroom scale or a public weigh sta­
tion .
The permitted tongue weight for your vehicle is 220 lbs (100 kg) .
Load distribution
Poor cargo load and dist ribution can negatively
impact veh icle ha ndling. To have the lowest im­
pact as possib le, load the trai ler according to
these criteria :
- Store objec ts p refe rab ly in t he ve hicle lugg age
compartment . The vehicle shou ld always carry
the heaviest possible load and the trai ler
sho uld have the lightest possible load .
- Distribute the load in the tra iler so that the
heavy objects are as close to the axle as possi­
ble .
- Secure objects from sliding out of p lace.
- Utilize the max imum perm itted tongue we ight
i f poss ib le .
Tires Set the tire pressure on your vehicle for a "full load"; see the t ire pressu re sticker
r=:;, page 176 .
If necessa ry, also adjust t he tire p ressure on the
tr ail er according to the manufactu rer's re com­
mendation.
W inte r ti res s hou ld be mounted on the ve hicle
a nd on the trailer dur ing wi nte r temperatures.
Outside mirrors
If you cannot see the traff ic be hind the tra iler
with the standard exterior mirrors, then you must attach addit ional exte rior m irrors. Adjust
them so you have a s ufficient visibility behind
you .
Exterior lighting
Follow the legal regulat ions regarding the light ­
i n g eq uipment on your trailer. Contact an author-
74
ized Audi dealer or author ized Audi Service Facili ­
ty for more information .
Befo re st arting to dr ive , check all lighting eq uip­
ment on the hitched trailer.
The head light range cont rol ad justs automat ica l­
l y to the light range of the headlights .
Safety chains Make sure the safety chains are correct ly applied
whe n pu lling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves. Howeve r, they must not touch the
ground.
(D Tips
- Use chocks when park ing on inclines if the
t railer is loaded .
- We recommend also having the vehicle in­ spected between the inspection intervals if
you a re towing a trailer frequently.
- Avoid driv ing with a tra iler dur ing the veh i­
cle b reak-in per iod.
Driving with a trailer
Driving with a trailer requires extra caution .
Speed
Adhere to the legal speed limits. Fo llow the legal
regu lations specific to the country.
As the speed increases, the dr iving stab ility o f
the trai ler decreases . Therefore you should not
exceed the maximum lega l speed limit when
there are unfavorable road, weather and/or wind
cond it ions. T his especially applies when driving
downh ill.
You m ust always reduce your speed as soon as
you notice even the slightest swinging motion of
the tra iler . Never try to "stra ighten out" the trai l­
er by acce lerating.
The weight d istribution is very poor if the vehicle
i s empty and the trai ler is loaded. However if you
must drive under these circumstances, then dr ive
especially slowly . ..,.

Intelligent Technology
-Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.

The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck

All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths

Driving safety
Important things to do before driving
Safety is everybody's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
before driving always:
.. Make sure that all lights and signals are operat­
ing correctly.
.. Make sure that the tire pressure is correct .
.. Make sure that all windows are clean and afford
good visibility to the outside .
.,. Secure all luggage and other items carefully
¢ page 102, ¢page 45.
.,. Make sure that nothing can interfere with the
pedals.
.. Adjust front seat, head restraint and mirrors
correctly for your height.
.. Instruct passengers to adjust the head re­
straints according to their height.
.. Make sure to use the right child restraint cor­
rectly to protect children
¢ page 134, Child
safety.
.,. Sit properly in your seat and make sure that
your passengers do the same¢
page 42, Front
seats.
.. Fasten your safety belt and wear it properly. Al­
so instruct your passengers to fasten their safe­
ty belts properly ¢
page 106 .
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
¢ _&. . Therefore:
.. Do not let yourself be distracted by passengers
or by using a cellular telephone .
.. NEVER drive when your driving ability is im­
paired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed limits and plain common sense . .,.

Using the prope r engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty 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 Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please

www .audiusa.com or www .aud icanada .ca.
Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
