252 Fuel supply and filling your fuel tank
_&. 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. •

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
