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.

254 Fuel su ppl y and fillin g yo ur fu el t an k
- 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

-Yo u can obtain refill bottles from any au­
thorized Audi dealer or other 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 .
- 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).
Checking and filling 259
-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

-Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure ?
The correct tire pressure is especially impor ­
tant at high speeds . The pressure sho uld
therefo re be checked at least once a month
and a lways before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tire pre ssures?
Ad just the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
store the new tire pressures i n the t ire pres­
sure mon itor ing system
~ page 294.
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion ca n lead sudden tire failure, loss of
cont ro l, col lision, ser ious persona l inju ry
or even death.
- Whe n the wa rning symbo l

the instrument cl uster, s top an d inspect
the tires.
- Incorre ct tire pressure and/or unde rinfla­
t ion can cause inc reased t ire wear and
can affect the handling o f the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sud den tire fa il-

- The driver is responsib le for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker o n the dr iver's s ide B-pil­
lar .
- Onl y when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system can work cor­
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage .
Therefore it is ess ential that th e drive r
observe t he spec ified t ire p ress ure val ues
for the tires and the cor rect pressures for
the func tion of the t i re p ress ure moni to r­

- D riving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, d rive at
red uced speed to the nearest service sta­
tion to check the t ire press ure and add
air as requ ired .
(D Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve s tem caps o n all whee ls are sec urely
mounted o n the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumpt ion.
