Static 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 refueling or filling a portable fuel container.
- For your safety, we strong ly recommend
that you do not travel with a portable fuel
container in your vehicle. The container, 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 portable fuel container whi le it
is anywhere in or on the vehicle (for exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can bui ld up
while filling and can ignite fuel vapors causing a fire.
- Always place a portable fuel container on
the ground before filling.
-Always keep the fi ller nozzle complete ly
ins ide the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozz le must always be in
contact w ith the container . Th is will help
prevent static e lectricity from discharg ing
and cause a fire .
- Never sp ill fuel inside the vehicle or lug­
gage compartment. Fue l vapors are highly
flammab le.
- Always observe local and state/provincial laws rega rding the use, storage and trans­
portat ion of fuel contai ners.
- Make certa in the fuel container meets in­
dustry standards (ANSI/ ASTM F852 -86) .
(D 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 correctly operated nozzle sw itches off automatically for the first time,
the tank is full . Do not try to add more fuel
Fu el a nd R efu elin g
because f uel 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 pollute the environment.
@ Tips
- Running your engine whi le refue lling may
cause vapors to escape or even cause fue l to
spill out of the tank. This would then sh ut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition turned on. The fuel gauge may otherwise not indicate the correct fuel level after refu­
elling .
- Diesel vehicles* are equipped with a diesel
m isfueling protector .
It allows the vehicle to
be fueled only with a d iesel fue l pump noz­
zle . A wo rn o r damaged nozzle o r a nozz le
that is too small may not be able to open
the diesel misfueling protector.
If this is the
case , try turning the nozzle before insert ing
it in the fuel filler neck, use a different fuel
pump or see your authorized A udi dealer or
authorized repair facility for assistance.
- The fuel fi ller f lap 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.

Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (Ad Blue) is injected into the ex­
haust system before
a nitrogen oxide catalytic
converter to reduce nitrogen emissions .
The AdBlue is carried in a separate tank in the ve­
hicle. The AdB lue usage accounts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used.
When a message about refilling the Ad Blue ap­
pears in the instrument cluster disp lay, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility ¢
page 219.

engine was facto ry-filled with a high-qua lity oil
which can usually be used throughout the entire
year.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Ma intenance booklet.
- Use only a high qua lity eng ine oil that ex-
pressly complies w ith the Audi o il quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to prov ide effective lubrication and coo l­
i ng of internal engine components, all internal
combust ion engines consume a certa in amount
of oil. Oil consumpt ion va ries from engine to en­
gine and may change sig nificantly over the life of
the engine. Typically, eng ines wi th a specified
break -in period (see¢
page 198) consume mo re
o il during t he b reak-in period than they co nsume
after oil consumption has stabilized .
Un der normal cond itions, the rate o f oi l con­
sumption depends on the q uality and viscos ity o f
the oil, the RPM (revolutions per min ute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the ox idat ion leve l of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may inc rease over
time unt il rep lacement of worn compone nts may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be estab­
li shed or spec ified. There is no alte rnative to reg­
u lar and frequent checking of the oil leve l, see
Note .

Cooling system
Coolant
T he engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
T he cooling system has been filled at the factory
with a permanent coolant which doe s not need to
be changed . T he cool ant consists of a mixture of
specia lly condit io ned water and the ma nufactur ­
e r's g lycol-basedcoo lant additive G 13 antifreeze
w ith a nticorros ion add itives (50% for USA mod­
e ls; 60% for Canadian models) . Thi s m ixt ure bot h
a ssures the ne cessary frost protection and pro­
tec ts meta l components in the engine 's cooling
system from corrosion and sca ling. It a lso raises
the boiling point of the coolant.
D o not red uce the conce ntra tion o f th e coo lant i n
the summer by add ing p la in wa ter.
The propor­
tion of coolant additive must be at least 50% but not more than 60 %
to maintain antifreeze
protection and cooling efficiency . If the coolant
frost protection is too low, the coolan t could
freeze and damage t he vehicle heat ing and en­
g ine cooling system .
For yea r-round driving, antifree ze is added at the
factory for tempe ratu res down to:
- -31°F ( -35°C) USA
- - 4 0°F ( - 40°C) C anada .
I f yo u mu st add coo lant, use a m ixt ure of wate r
a nd coolant add it ive. Mixing the coolant additive
with d istilled water is recommende d.

@ Note
- Be fore winte r sets in , have the coo lant
checke d to see if the coolant additive in you r
vehicle is sufficient to meet the climate con­ diti ons. This is espec ia lly important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the p ropo rtion
o f coolan t addi tive to 60%.
- Whe n adding coolant additive to your cool­
