2014 AUDI Q5 engine

It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter.
It i s 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 outside 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 cou ld
result in serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
(D Note
- Refueling with gasoline when your vehi­
cle has a d iesel 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 amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed .
- Vehicles with diesel engines must never
be refueled or dr iven with gasoline, kero­
sene, heat ing o il, or other non-specified
fuels that have not been expressly ap­ proved for use with the diese l eng ine.
Other kinds of fuel can cause se rious
damage to the fue l system and the en­
gine that is not covered by any Audi Lim ­
ited Warranty.
- If Diesel fuel shou ld get on any rubber
hose, it must be wiped off immediate ly.
Then wash the contaminated hose por­
tion with soap and warm water. Do not

Fuel tank
Fuel filler neck
The fue l filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power lock ing system should fa il, you
can still open the flap manually - for detailed
instruct ions see
¢ page 22 7.
You can find the fuel tank capacity of your ve ­
hicle in
~ page 290 .
The label on the inside of the fuel filler flap
tells you the correc t fuel for your vehicle. For
more information about fuel specifications,
see ~
page 222.
Your vehicle fue l tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and pollut ing the environment wh ile you
refue l your vehicle . In order to fi ll the tank
properly while protecting the environmen t,
please fo llow this refueling p rocedure caref ul­
ly .
A WARNING
-
Under normal operating conditions, never
carry additional fue l 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 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 con ­
tainer meets industry standards (ANSI/
ASTM F852 - 86).

gine).
A 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 injur ies.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fue l spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause spa rks that can ignite f uel va­
pors and cause a fire .
- Never get back into your vehicle whi le re­
fue ling.
If in exceptional circ umstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static e lectricity before touching the fill­
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors
released du ring refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­ eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel conta iner in your vehicle . The con­
tainer, fu ll o r empty may leak and could
cause a fire, especially i n a c rash.
- If , under exceptional c ircumstances, you
must transport a portab le fuel conta iner,
p lease observe the following: .,.

-Never f ill a portable 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 bu ild up while filling and can ig­
nite fuel vapors causing a fire .
- Always place 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 fill ing 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 spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ig hly 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).
(D Note
If any fuel has spilled onto the car, it
should be removed immediate ly to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add
more fue l because fuel may spill out. In
addition, the expansion space in the fuel
tank will be fi lled -causing the fue l to
overflow when it becomes warm and pol­
lute the environment.
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fuel to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
Fuel su ppl y and filling your fuel ta nk 22 7
-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 able to open the diesel misfueling
protector. If this is the case, try tu rning
the nozzle before insert ing it in the fuel
filler neck, use a different fuel pump or
see your authorized Audi dea ler
or au­
thorized repair facility for assistance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.
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
Applies to vehicles: wit h diese l en gi ne
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 emissions.
The Ad Blue is stored in a separate tank in the
vehicle . The Ad Blue 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 authorized Audi dealer or qualified
workshop as soon as the AdBlue refill mes­ sage appears in the instrument cluster
c;,page229.
A WARNING
Failure to heed Ad Blue 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, persona l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank ru ns dry.
