2013 AUDI Q7 fuel cap

258 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system shou ld fail, you
can still open the flap manua lly -for detailed
instructions see ¢
page 261.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 322 .
The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see ¢
page 256.
Your vehicle fuel tank has an on-board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING
-Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, 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 and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the ..,.

container meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is complete ly empty. The irregular supply
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalyt ic converter.

er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Fuel suppl y and filli ng your fuel t ank 259
Refuelling p ro cedur e
• Insert the fuel nozz le from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medi um refue lling rate so that the
nozz le switches off automatically when the
tank is full.
Pu tting th e fuel cap bac k on
• After fi lling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 2 7
to come on (only vehicles with gasoline en­
gine).
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off wh ile refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over­
f low. Fue l spray and overflowing fue l can
cause a fi re.
- Never use a cel lu lar telephone while re­
fueling. The electromagnetic rad iation
can cause sparks that can ignite f uel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling. If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
stat ic electricity before touching the fill­
er nozzle again. Static e lectricity can
cause sparks that can ignite fuel vapors re leased du ring refuel ing .
- Never smoke or have an open flame any­
where in or near your veh icle when refu-
eling or filling a portab le fue l conta iner.

- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portab le fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­ n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
-Always keep the fi ller nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full. Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol­
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­
erwise not indicate the correct fuel level
after refuelling.
- Diesel vehicles* are equipped with a die­ sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au­
thorized repair facility for assistance.

Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

General information
App lies to vehicles : with diesel engine
On vehicles w ith select ive catalytic reduction,
an urea solut ion (Ad Blue ®) is injected into the
exhaust system befo re a nitrogen oxide cata­
lytic converter to reduce nitrogen em iss ions.
The AdBlue is stored in a separate tank in the
veh icle. The AdBlue usage accounts for ap­
p rox imately 0.5% to 1.2% of the diese l fuel
that is used. The Ad Blue tank capaci ty is ap ­
pr ox ima tely 6 gallons (23 liters).
You must refill the Ad Blue or have it refilled
by your authorized A udi dealer or qualified

workshop .
- Follow the Ad Blue manufacturer's in­
struct ions for usage and storage. •
•

-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
Checking and filling 265
- First, fully apply the parking brake,
move selector lever to "P" (Park) .
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
