Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels ore powered.
General information
In all wheel dr ive, the driving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as well as
the current road conditions . A lso see
c> page 159, Electronic stabilization control
(ESC).
The all whee l drive concept is designed for high
engine power. Yo ur vehicle is exceptionally 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
c> ,&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on veh icles w ith all wheel dr ive
c> page 269, Snow chains.
Replacing tires
For vehicles with a ll wheel d rive, only wheels with
the same rolling circumference should be used .
Avoid wheels with different tread depths
c> poge 260.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficu lt terrain . Also see<=)
page 302.
A WARNING
--Also, in veh icles with all whee l drive, adapt
your driving style to the current road and
traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks.

Check ing and F illing
Selective catalytic
reduction (AdBlue)
General information
Applies to vehicles: with diesel engine
In vehicles with selective cata lytic reduction, a
urea solution (AdB lue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
Ad B lue is the marketing name for Diesel Exha ust
Fl uid (DEF).
The AdBl ue is carried in a separate ta nk in the ve­
hicle. The Ad Blue usage accounts for approxi­
mate ly 0.5% to 1.2% of the diesel f uel that is
used .
W hen a message about refilling the Ad B lue ap­
pears in the instrument cluster disp lay, you must
refill the Ad Blue you rself or have it refilled by an
author ized Audi dealer or authorized Audi Service
Facility ¢
page 235.
A WARNING
-
Failure to heed AdBlue refill informat ion in
the instrument cluster can prevent the vehicle
from being started and dr iven . If the vehicle
cannot be driven and an emergency arises,
perso na l in jur y can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry .
(D Tips
-The instrument cluster display indicates the
distance rema ining t hat can be driven
¢ page 234. If the AdBlue tank is com­
plete ly empty, the engine wi ll not start
again after the ignition is sw itched off.

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions d ue to failure
to follow rec ommended maintenance and use
requireme nts as s et forth in the Audi Owner's
Manual and Warranty & Maintenance booklet.
- Use only a high quality engine oi l that ex-
pressly complies with the Au di 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.
- Vehicles with gasoline eng ine: ACEA A3 o r
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles with diesel eng ine: ACEA C3 or
API CF with a viscosity grade of SAE OW-30
or SAE SW -30.
- For more information about engine oil that
has been approved for your vehicle, please
contact e ither your authorized Audi dea ler
or Audi Customer Relat ions at
1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.aud icanada.ca.
Engine oil consumption
The engine in your vehicle depends on an ode-
;::: quote amount of oil to lubricate and cool all of
~ its moving parts . co ,....,
~ In order to provide effective lubr ication and cool-,....,
:=: ing of internal engine components, all internal
Ch eck ing and Filling
combustion engines consume a certain amo unt
of oil. Oil consumption varies from engine to en­
gine and may change s ignificantly over the life of
the engine. Typ ically, engines w ith a specified
break-in period (see¢
page 77) consume more
o il during the break-in per iod than they consume
after o il consumption has stab il ized.
Under normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the amb ient tem­
perature and road co ndit ions. Further facto rs a re
the amount of oi l di lution from wate r condensa­
tion or fuel resid ue and the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unti l replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab ­
li shed or specified. There is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine oil leve l warning symbo l l!I
in the instrument cluster lights up, you should
check the oi l level as soon as possible
¢
page 242. Top off the o il at your earliest con­
venience ¢
page 242.
A WARNING
-Before you check anyt hing in the engine com-
partment, always read and heed all WARN­
INGS
¢page 236.
(D Note
Driving wit h an insufficient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressu re wa rning display. is not
an indicator of the oi l le vel. Do not rely on
i t. In stead , check th e oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before goi ng
on a long trip .

Radiator fan
The radiator fan switches on outomotico/ly by it­
self.
An auxiliary elect ric radiator fan sw itches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fa n
can cont inue runn ing fo r up to 10 minutes -even
with the ignition off . It ca n even switch on again
later by itself¢.&. , if
- the temperature of the engine coolant r ises due
to the heat bu ild -up from the engine in the e n­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight .
A WARNING
-To reduce the risk of pe rsonal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the eng ine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coo lant reaches a
certain tempe rature and w ill cont inue to run
until the coolant temperature drops.

ment.
Ch eck ing and Filling
Plug -in hybrid drive* : you can find important in ­
formation about the high -vo ltage battery under
¢ page 98.
The battery in yo ur Audi does not need any ma in­
tenance under
normal operating conditions . Audi
recommends having the electrolyte level check
by an authorized Audi dealer or author ized Audi
Service Facility when there are
high outside tem­
peratures or when dr iving all day. The e lectrolyte
level should also be checked each time the bat ­
tery is charged¢
page 249.
Have the battery checked when you bring your ve­
hicle in for an inspection. It is a good idea to re­
place the battery if it is more than 5 years old.

- Following the service intervals is critical to
maintain ing the service life and va lue of
your vehicle, especially the engine. Even if
the m ileage on the vehicle is low, do not ex­
ceed the time for the next service.
- Calculating the time to the next oil change
i s interrupted when the ve hicle battery is
disconnected. If the vehicle is not driven for
252
a long period of time, check the mainte ­
nance schedule so that you can fo llow the
maintenance intervals.

Tires and wheels
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear .
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in. (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion
¢ fig . 203 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones
¢ ..&. .
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires

country.
262
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice
versa . This will allow the tires to
have approximately the same
length of service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 288.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety. ,..
