CD only functions when the ignition is
sw itched on. To prevent engine damage, p lease
observe the following notes about the tempera­
ture ranges.
Cold range
If on ly the LEDs in the left area of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full ac­
celerating and heavy engine loads .
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on. If
the . indicator light in the Infotain­
ment system display turns on, the coolant tem­
perature is too high
c::;, page 12.

(I;} Note
-Aux iliary head lights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en ­
gine load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating w ill increase. See an authorized
Audi dealer or author ized Audi Service Fa ­
cility for assistance .
Fuel level
The indicator@ only func tions when the ignition
i s sw itched on. If the fuel level drops below 1.9
gal (7
L), a red LED will light up and the rD indi­
cator light will turn on
c::;, page 15. The LED
blinks red when the fuel level is very low.
The fuel tank capacity of your veh icle is listed in
the
Technical Data section c;, page 288. ..,.

Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends , we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engin e
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TI ER Dete rgent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle Limited Warranty.

Refueling
Fueling procedure
Your vehicle is equipped with a capless fuel filler
system .
Fig. 172 R ight rea r sid e of the vehicle : ope ning the fuel
fil ler door
Fig. 173 R ig ht rea r sid e of t he ve hicle: fuel pum p nozz le
in ser ted
The fuel filler door is unlocked or locked by the
central locking system.
.. Press on the left side of the fuel filler door to
open
r:::;, fig . 172.
.. Insert the fuel pump nozzle all the way into the
fuel tank filler neck
r:::;, fig. 173. Make sure it is
seated correctly.
.. Begin fueling. Once the fuel pump no zzle turns
off the first time, the fuel tank is full. Do not
continue fueling, or else the expansion space in
the tank will be filled with fuel.
.. After the fuel pump has switched off, wait five
seconds before removing it to allow the rest of
the fuel to finish dripping into the fuel tank.
.. Close the fuel filler door and then press on the
left side until it latches.
The correct fuel type for your vehicle can be
found on a label located on the inside of the f uel

_& WARNING
An improper f uel ing p rocedure and improper
hand ling of fue l can lead to exp losions, fires,
severe b urns and other injuries .
- Do not smoke and keep away from open
flames .
- T he ig nition m ust be switched off whe n re ­
f ueling .
- Cell pho nes, radio devices and o ther radio
equipment s hou ld always be switched off
w hen refueling . Electromagnetic rays cou ld
cause sparks and start a fire .
- If you do not insert the fuel pump nozzle a ll
the way into the filler tube, then fue l can
leak out. Spilled fue l can ignite and start a
fire.
- Never get into the vehicle when refueling. If
there is an exceptional s ituation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle aga in . This will reduce the
r isk of electrostat ic d ischarge that can cause
flying sparks . Sparks can start a fire when
ref uel ing .
_& WARNING
We recommend that you do not t ransport any
fue l co nta iners in t he veh icle. Fue l cou ld leak
out of the containe r and ignite, espe cially dur ­
ing an accident. This can cause exp losions,
fires and injuries .
- If you must transport fuel in a fue l contain ­
er, please note the following:
Ch eck ing and F illing
- Always place a fue l container on the
ground before filling . Never fill the fue l
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
wh ile refueling and the fuel vapors could
i gnite .
- For fuel containers made of metal, the fuel p ump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,
stor ing and t ransporti ng f uel conta iners.
- Make su re that the fuel containe r meets
t h e in dust ry standa rds, for example ANS I
o r ASTM F8S2 -86.
@ Note
- Remove fuel that has overflowed onto any
veh icle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel
tank is completely
empty. The irregula r supply of fue l that re­
sults from that can cause eng ine misfi res.
U nc ombus ted fuel will ente r th e exhaus t
system and increase the risk of damage to
the cata lytic converter.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise f uel
ca n leak o ut w hen the ve hicle is warming up.
(D Tips
- If adverse weat her co nd it io ns cause the f uel
filler door to freeze shut, p ress o n the cen ­
t er of the fi ller door wit h the hee l of your
hand and then try opening it again .
- Th e fuel fi ller door on yo ur vehicle does no t
lock if yo u lock the vehicle from the inside
using the central locking switch.
(D Tips
- Yo ur vehicle is eq uipped w ith a misfue ling
guard. It a llows the vehicle to be f ueled on -

Emissions control
systems
Catal ytic conve rt er
The vehicle may on ly be driven with unleaded
gasoline, otherwise the catalyt ic converter will be
destroyed.
Never drive until the tank is completely empty.
The irregular supply of f uel that results from that
can cause engine m isfires. Uncombusted fuel will
enter the exhaust system, wh ich can cause over­
heat ing and damage to the catalyt ic converter .
A WARNING
The temperature of the exhaust system is
high, both when d riving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become ho t. This could result in bu rns.
- Do not park your vehicle ove r flammable
materials such as g rass or leaves because
the high temperat ure of the em iss ions con­
trol system co uld s tart a fire.
- Do not apply underbody p rotectant in the
exha ust system area, because this inc reases
the risk of fi re.

-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important safe­
ty precautions
inc:> page 256,
Tires and vehicle load limits .
-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 t ire pressure in ­
creases tire wear and has a
negative effect on driving and
braking behavior, which in ­
creases the risk of an acc iden t.
