fuel AUDI Q7 2014 Owner´s Manual

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 fuel 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 start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine id le 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 serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Refueling with gasoline when your vehi­
cle has a diesel engine can cause very se­
rious and expens ive engine and fuel sys­
tem damage that is not covered by any
A udi Limited Warranty.
- If you put any amou nt of incorrect fuel in
the fuel tank, do not start the engine un-

der any circumstances. Immediately con­
tact the nearest authorized Audi dea ler
or authorized Audi Service Fac ility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start ­
ed .
- Veh icles with diesel engines must never
be refueled or driven with gasoline, kero­
sene, heating oil, or other non-specified
fuels that have not been expressly ap­ proved for use with the diesel engine.
Other kinds of fuel can cause serious
damage to the fuel system and the en­
gine that is not covered by any Audi Lim­
ited Warranty.
- If Diesel fuel should 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.

The label on the inside of the fuel filler flap
tells you the correct fuel for your veh icle. For
more information abo ut fuel specifications,
see c::>
page 249.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and pollut ing the environment while you
refuel yo ur vehicle. In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful-

_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause afire in a collision. If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F8S2 -86).
(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supp ly
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling
Fig . 232 Right rear vehicle side : Open ing t he fue l filler
fl ap
Fig. 233 Fu el cap hooked on the opened fue l filler fl ap
When adding fuel, the ignition and any cellu­
lar phones in the vehicle must be switched
off . When activating the central locking, the fuel
filler flap is automatically unlocked or
locked. Refuel the vehicle with the ignition
turned
off.
Taking the fuel cap off
.,. To open the fue l filler f lap, press on the left
side of the flap¢
fig. 232 -arrow-.
.,. Unscrew fue l filler cap counter-clockwise
and hang it on the fuel filler flap ¢
fig. 233.
.,. Check the label on the inside of the fuel fill­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Refuelling procedure
.,. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it wi ll
go .
.,. Select a medium refuelling rate so that the
nozzle switches off automatically when the
tank is fu ll.
Putting the fuel cap back on
.,. After filling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
.,. Close the fuel filler flap.
T o avoid fuel spilling 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 27
to come on (only vehicles with gasoline en ­
gine) .
_&. WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe bu rns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fu lly into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
f low . Fu el spray and overflowing fue l can
cause a fire.
- Never use a cellular telephone while re­
fue ling. The electromagnetic radiat ion
can cause sparks that can ignite fuel va­
pors and cause a fire .

-Never get back into your vehicle while 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
static electricity before touching the fill­
er nozzle again. Stat ic electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.
- For your safety, we strongly recommend
that you do not trave l w ith a portab le
fuel container in your vehicle. The con­
tainer, full or empty may leak and cou ld
cause a fire, especia lly in a crash .
-If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for examp le, in the luggage compart­
ment, or on the trunk). Static electr ici­
ty can bui ld up while fi lling and can ig­
nite fuel vapors causing a fire.
- Always p lace a portable fuel container
on the ground before filling.
-Always keep the filler nozzle complete­
ly inside the portable container before
and during filling .
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. This will
he lp prevent static electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852 -86).

@ Note
If any fuel has spilled onto the car, it
shou ld be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank w ill be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
0) Tips
-Running your eng ine while refuelling
may cause vapors to escape or even
cause fuel to sp ill out of the tank . Th is
would then shut off the fuel nozzle be­
fore the tank is ful l.
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­
erwise not indicate the correct f uel level
after refuelling.
- Diesel vehicles* are equipped with a d ie­
sel misfueling protector . It allows the
vehicle to be fueled only with a diese l
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before inserting it in the fuel
filler neck, use a different fuel pump or
see your authorized Aud i dea ler or au­
thorized repair facility for assistance. •

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (Ad Blue) is injected into the
exhaust system before a nitrogen oxide cata­ lytic converter to reduce nitrogen emiss ions.
The AdBlue is stored in a separate tank in the
vehicle. The AdBlue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by your author ized Audi dealer or qualified
workshop as soon as the AdBlue refill mes- sage appears
in the instrum ent cluster
r=>page 255.
.&_ WARNING
-
Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­ hicle from being started and driven. If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry.
(D Tips
- The instrument cluster disp lay ind icates
the distance remaining that can be driv­
en
r=> page 254. If the AdBlue tank is
completely empty, the engine will not
start again after the ignit ion is switched
off.

til fluid stops flowing into the tank.
• Turn the bottle to the left without pressing
on the bottom .
Closing the filler tube
• Turn the cap clockwise on the filler tube
with the lug wrench until you hear it tighten
completely.
• Close the tank cover.
After filling
The vehicle must be driven. The system may
take up to two minutes to detect that the
Ad Blue has been filled.
• If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster , switch the ignition on
for about 15 seconds before starting the en­
gine.
A WARNING
, -
AdBlue can irritate the skin, eyes and res-
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
Q) Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the Ad Blue and do not di­ lute it with water.
-AdBlue is not a diesel additive . Do not
add it to the diesel tank. If Ad Blue is
mixed with diesel fuel, it can lead to
damage to the engine and the Ad Blue
tank system. The Limited New Vehicle
Warranty does not cover such damage.
- Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet. Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue has already crystal­ lized, 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 vehi­
cle. If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow Ad Blue to come into con­
tact with clothing. If there is contact
with the fluid, flush immediately with
plenty of water.
(D Tips
- You can obtain refill bottles from any au­
thorized Audi dealer or other qualified
workshop .
- Follow the Ad Blue manufacturer's in­
structions for usage and storage.

258 Checking and filling
-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. Wait 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
th ick 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: -
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

C han gin g the en gin e o il
The engine oil and oil filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls specified in your vehicle 's War­
r anty
& M aintenance booklet. Do not ex ceed
t hese intervals -harmf ul depos its from old
engine oi l can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inte r­
va ls is so very important because the lub ric at­
ing p roperties o f oi l decrease grad ually during
norma l vehicle use . If you are not sure when
you have yo ur oi l changed, ask your a uthor­
ized A udi Service Advisor.
Unde r some ci rc u mstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing po int for
l ong periods .
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a short time . This is no rmal and is not
a reason to change the o il mo re often than
r ec om mended.
Damage or malfun ctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine oil
that complies with Audi oi l standard

· Engine oil consumption
To provide effective l ubr ication and cooling for
interna l eng ine parts, all interna l combustion
engines use some oi l. Oi l consumption varies
from eng ine to engine and may change over
the life of the engine . Engines tend to use
more o il du ring the b reak-in period tha n they
do afterward, when o il cons umption has sta­
bilized. Depend ing on the way the vehicle is
driven and the operating conditions, oil con­
s u mption can be up to
1 quart per 1,200
miles (l liter per 2,000 km) . Consumption
may be higher within the first
3,000 m iles
(5,000 km) .
U nder normal conditions , the rate of oi l con ­
s u mption depends on oi l quality as well as vis­
cosity, engine speed (rpm), outs ide tempera ­
ture, road conditions, the amount of oil dilu­
tion caused by condensed water or fue l resi­
due, and ox idat ion of the o il. Oi l consumption
may increas e with eng ine wear over time, un­
t il rep lacement of worn engine pa rts may be­
come ne cessa ry.
Because of all these var iables, there is no
standard o r "n orma l" rate of o il cons umption .
We urge you to check the engine oil level at
regular interval s, preferably every time y ou
fill the fuel t ank, and always before a long
trip .
The oil pres sure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while dr iving (above 1500 rpm), a
buzzer will sound. It indicate s that the oil
pressure is too low . Stop the engine immedi ­
ately , check the engine oil level and add oil if
necessa ry. If the engine oil level is normal,
but the l ight continues to fla sh, do not keep
driving or let the engine idle, as damage may
occur .

262 Checking and filling
If you believe your engine uses too much oil,
we recommend that you consult your author­
ized Audi dealer so that the cause of your con ­
cern can be properly diagnosed. Keep in m ind
that accurate measurement of oil consump­
tion requires great care and may take some
time. Your Audi dealer has inst ruct ions for
how to measure oil consumption accurately .

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
