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.

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, exp lo­
sions or serious in juries.
- Fuel ignites eas ily and can cause serious
burns and other injuries.
-
- If you do not switch the eng ine off when fu­
eling and/or do not insert the fuel nozz le
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and sta rt a fi re .
- Do not use the telephone while fueling. The electromagnet ic rays can cause spa rks,
w hich can ignite fuel vapors and sta rt a fi re .
- Do not s it in you r vehicle while fueling . If
yo u must make an except io n and enter your
vehicle again wh ile fue ling , close the door
and touch met al to discharge static electri c­
ity befo re touching the fue l nozzle. Static
elect ricity can create sparks, whic h can ig ­
nite vapors when f ue li ng.
- Do not smoke or have an open flame i n the
area when fueling your vehicle or filling a
fuel container because this increases the risk of an explos ion.
- For your safety, carrying f uel containers in
your vehicle is not recommended. Whether
full or empty, the conta iner can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­ port a fuel container, note the following:
- Never fill the fuel containe r with fuel
while it is in or on the vehicle. S tat ic elec­
t ricity is d isc har ged when filling wh ich can
Ch eck ing and Filling
cause the fuel vapors to ignite and in­
creases the risk of an exp losion.
- Always place a fue l container on t he
ground before fill ing .
- Always hold the fue l nozzle completely in
the fuel conta iner when fill ing.
- If the fuel containe r is made of meta l, the
fuel nozzle must always be in contact with
the container when filling it with f uel. This
~revents static elect ricity from discharg­
ing .
- Never spill fue l in the vehicle or the lug­
gage compartment. Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Fo llow lega l requirements when using,
stor ing and transporting fuel containers .
- Make su re the f uel container conforms to
industry standards (ANSI/ASTM F852-86).
(D Note
- Remove spilled fue l from vehicle pa int im­
mediately, because it can damage paint.
- Never drive unt il the fuel tank is complete ly
empty. The irreg ular s upply of fue l that re ­
sults from that can cause eng ine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
t he cata lytic converter .
- If the fuel tank runs complete ly empty in a
vehicle with a
diesel engine , the ignition
must remain switched on fo r at least 30
seconds afte r refueli ng before starti ng the
eng ine.
It may t ake longer than u sual fo r
t he engine to s tart, even up to a minute .
T his is because t he air must f irst b leed ou t
of the fue l system when starting the engine.
@ For the sake of the environment
- If the fue l nozzle is use d co rrectly, it w ill in­
dica te t hat the t ank is full the first t ime it
switches off a utomatica lly. Do not try to
add more fuel, because it can spill ove r. A l­
so, the expansion space in the tank w ill fill
'
w hich can resu lt in fuel sp illing out when it
becomes wa rm and pollut ing the e nviron­
ment.

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
side.

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.

Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
¢ .&. .
.8, WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns!
Wait until no steam or coolant flows out.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short circuits in the electrical system,
especially the battery.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en-
-
gine running, there is additional danger due ~

Tires and wheels
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehic le manufac­
turer for a tire of a designated
size that has not been driven for more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted.
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, air condi ­
tioning and additiona l weight of
op tional equipment.
E x tra load tire
means a tire designed to operate
at higher loads and at h igher in-
2 56
flation pressures than t he corre­
sponding standard tire. Extra load
tires may be identified as "XL",
"xl" , "EXTRA LOAD" , or "RF" on
the sidewall.
Gross A xle Weight Rating
("GAWR" )
means the load-carrying capacity
of a single axle system , measured
at the tire-ground interfaces.
Gross Vehicle Weight Rating ("GVWR")
means the max im um total loaded
weight of the vehicle .
Groove
means the space between two ad­
jacent tread ribs .

Tires and wheels
A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-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 266,
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 tire pressure in­ creases tire wear and has a
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change . If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8- pillar, always follow the specifica-
264
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load c:::>
table on
page 265
or for a full load
when the vehicle is partially
loaded.
tion on the 8-pillar label c:::>
page 263, fig. 204.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom- mended tire pressures in cold ..

The "GVWR" includes the weight
of the basic vehicle, all factory in­stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­ sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
Tires and wheels
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the driver's side B-pillar
¢ page 263,
fig. 204.
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to- tal load being transported -,..
