A pp lies to veh icles: w ith plug -in hybrid drive
Two options are available for charging the vehi­
cle:
- Charge at a public charging station with a spe­
cial charging cable*
c::>page 112.
- Charge with household and industrial power
sockets using the Audi e-tron charging system
c::> page 112.
Environmental conditions when using the
charging system
-Operating temperature : -13 °F (-25 °C) to 95 °F
(+35 °C)
- Humidity:
5% to 95%, non-condensing
- 13,000 feet (4,000 meters) maximum above
sea level
110
Warnings when using the charging system
£
Surfaces can become very hot when
in direct sunlight.
&~
Incorrect use increases the risk of
electric shock.
~"-
Do not use any extensions cords or
cable reels.
~
Do not use any travel adapters.
~~
Do not use any power strips.
~~~
Do not use any charging cables with
damage to the electronics or the
connecting wires.
.&_ WARNING
-
Sockets that are installed incorrectly can
cause electric shock or fire when charging the
high-voltage battery using the vehicle charg ­
ing connection.
- Installation and setup of the household con­
nection for the Audi e-tron charging system
may only be performed by a qualified elec­
trician. The qualified electrician is thereby
fully responsible for adhering to applicable
standards and regulations.
- Make sure that the selected charging con­ nection is suitable for drawing 16 amps .
- Make sure that the
110 volt socket is
grounded and shielded from water.
- Always check the fuse for the GFI outlet be­
fore connecting the charge cable.
- Never use a damaged GFI outlet.
- Read and follow the safety precautions in
the Audi charging dock* assembly instruc­
tions.
.&_ WARNING
If you are not familiar with the socket or the
e lectrical installation or it has not been
checked by qualified experts, never use it for
charging. Even very low charging currents can
cause ser ious damage and in particular fires if
the socket or electrical installation is in bad
condition. If necessary, get expert assistance

0 > co ,...., -If you are unable to determine whether or
not a particular fuel blend meets the speci­
ficat ions, 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 fue ls diffe r­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Warrant ies .
- If you experience a loss of fue l economy or
driveability and pe rformance prob lems due
to the use of one of these fuel blends, we r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Dete r­
gent Gasoline, please go to the official website (www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
(D Note
Damage o r malfunction due to poo r fuel q ual­
ity is not covered by the Aud i New Vehicle
Limited Warranty.
Ch eck ing and Filling
Diesel fuel
Applies to vehicles: wi th diesel engine
Always use U LSD (Ultra Low Sul fur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM D97S.
D iesel f ue l w it h con cen tratio ns of b iod iesel h igh­
er than 5% such as B11, B2 0 or B100 are strictly
prohib ited .
Se rvice station fuel pumps are labe led with the
correct f uel info rmation for easy recog nition by
the user. If the d iesel f uel pump is no t labeled
ask the station operator wha t fu el is being dis ­
pensed before filling up your vehicle .
UL SD No. 2 m ay not be available outside the USA
and Can ada . Be s ure to che ck before traveling to
other countries .
UL SD No . 2 can become thic ke r i n ve ry co ld tem­
peratures, and th is can imp air the engine's s tart ­
ing and running. Depend ing on the season, gas
stations provide ULS D No . 2 that flows be tter in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
soley for use w ith ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow imp rovers. These contain substances
that will severely damage the fuel system and the engine . Such damage will not be
covered by yo ur New Vehicle Limi ted War­
ranty .
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Immed iately contact the
nea res t author ized A udi dealer or author­
ize d Aud i Serv ice Facili ty fo r ass ist ance.
T hese f uels conta in su bstances tha t can se­
verely damage the fuel system an d the en­
gine if the engine is started.
- If the diese l fuel quality is poo r, it may be
necessary to have the wate r drained from
the water sepa rato r in the
fuel filter more
often t han spec ified in the maintenance
schedule. This can help reduce engine mal­
functions <=>

Checking and Filling
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you can
still open the flap manually· for deta iled instruc­
tions see~
page 232 .
You can find the fuel tank capacity of your vehicle
in
c::;, page 303 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle . For more in­
formation about fuel specifications, see
c::;, page 228 .
Your vehicle fuel tank has an onboard refuelling
vapor recovery system . This feature helps to pre·
vent fuel vapors from escap ing from the tank and
polluting the environment while you refuel your
veh icle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully .
.&, WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful a nd always observe local and
state laws regard ing the use, t ransportation
and storage of such fue l containers. Make cer·
tain the container meets industry standards (ANSI/ASTM F852 · 86).
(D Note
Never drive yo ur vehicle unt il the fuel tank is
completely empty. The ir regula r supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Checking and Filling
@ Tips
Fue l can age and may lead to prob lems when
starting. Audi recommends replacing the fuel
in your vehicle within six months.
@ Tips
- If the engi ne is running while fueling, va­
pors can escape or the fuel can spill over.
Because of th is, the fuel no zzle switches off
before the tank is full.
- Do not fuel the vehicle when the ignition is
switched on. Otherwise, the fuel gauge may
not show t he correct level after fueling the
vehicle .
- Diesel veh icles are equ ipped with a diesel
misfueling guard
1>. It allows the vehicle to
be f ueled on ly w ith a diesel fuel pump noz­
zle .
- A wo rn o r damaged nozzle or a nozzle that
i s too smal l may not be ab le to open the
diesel misfueling protector . If this is the
case, try t urning the nozzle before inserting
i t in the f uel fille r neck, u se a d ifferent fue l
pump or see an aut horized Audi dea ler or
a uthorized Audi Service Facility fo r assis­
tance .
- The misf ueling guard does not open when
adding fue l from a fue l conta iner . You can
bypass it by adding the diesel fuel slow ly.
- The fuel filler door on your ve hicle does not
l ock when you lock the vehicle from the in­
