· Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat.
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
~ ,&. .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat.
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to pull the belt
out of the retractor. The convertible locking re­
tractor is now activated.
.. Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly.
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
_&. WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch the Start-Stop-System* off
when driving through water
9 page 79.
@ Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water (corrosion).
Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
... Always use lead-free gasoline 9 page 208,
Fuel supply.
... Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
9 page 220, Adding engine oil~-
.,. Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
Driving and the environment
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
CD Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil level
9page220.
- Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur

Fuel and Refueling
These fuels contain substances that can se ­
verely damage the fue l system and the en­
gine if the engine is started .
Refueling
Fuel filler neck
The fuel fill er neck is located on the right rear
side panel beh ind the fuel fil ler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see ¢
page 212.
You can find the fuel tank capacity of your vehicle
i n
¢ page 271 .
The label on the inside of the fuel filler flap tells
you the correc t fuel for you r vehicle . For more in­
formation about fuel specifications , see
¢ page 208 .
Your vehicle fuel t ank has an onboard refuelling
vapor recovery system . This fea tu re helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully.
8_ WARNING
Under normal operating conditions, never car­
ry additiona l fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
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 always observe local and
state laws regard ing the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. T he irregular supply of
fue l can cause m isfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Refuelling
Fig. 178 Righ t re ar v ehicl e side : O penin g the fuel fill er flap
Fig. 179 Fuel fille r flap w it h att ach ed fuel c ap
When act iv a ting the central locking, the fuel fill­
er flap is automatically unlocked or locked. Re ­
fuel the veh icle with the ignition switched
off.
Taking the fuel cap off
.. Press the left s ide of the fuel filler flap to open
i t ¢
fig. 178 -arrow-.
.. Unscrew fuel filler cap counter-clockwise and
hang it on the fuel filler flap~
fig. 179.
.. Check the label on the inside of the fuel filler
flap to determine if the vehicle must be fueled
w ith gasoline or diesel fuel.
Refuelling procedure
.. Insert the fuel nozzle from the gasoline pump
into the fuel filler neck as far as it will go .
.. Select a med ium refuelling rate so that the
nozz le switches off automatica lly when the
tank is full.
Putting the fuel cap back on
.. After filling your tank, twist the fuel filler cap
clockw ise as far as it will go .
.. Close the fuel filler flap.

To avoid fuel spilling or evaporating from the fuel
tank always close fuel filler cap properly and
completely. An improperly closed fuel filler cap
may also cause the MIL lamp
c> page 28 to come
on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
-
-Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler nozzle again.
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 strongly 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 while it
is anywhere in or on the vehicle (for exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors
causing a fire.
- Always place a portable fuel container on
the ground before filling.
Fuel and Refueling
- Always keep the filler nozzle completely
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 discharging
and cause a fire.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable .
- Always observe local and state/provincial
laws regarding the use, storage and trans­
portation of fuel containers.
- Make certain the fuel container meets in­ dustry standards (ANSI/ ASTM F852 -86) .
(D Note
If any fuel has spilled onto the car, it should
be removed immediately 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 fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D 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 before the tank is full.
- Do not refuel your vehicle with the ignition
switched on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- Diesel vehicles* are equipped with a diesel
misfueling protector.
It allows the vehicle
to be fueled only with a diesel fuel pump nozzle. A worn or damaged nozzle or a noz­
zle that is too small may not be able to open
the diesel misfueling protector. If this is the .,..

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consu Lt your Audi dealer to
have the cause of your concern properly di­
agnosed . Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
Fig. 187 I n fo tai nme nt: oil level indic a to r
• Park your vehicle on a level surface.
" Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
" Select : the
ICAR I function button > (Car)* Sys­
tems
control button > Service & control > Oil
level.
.. Check the oil level in the Infotainment system
display ¢
fig. 187. Add engine oil if the bar of
the oil level indicator is near "min"
¢page 220.
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0 .5 liter per
220
1,000 km). Consumption may be higher within
the first 3,000 miles (5,000 km).
Because of this, the engine oil level must be
checked regularly. It would be best to check each
time you refuel your vehicle and before long
drives.
{!) Tips
The oil level indicator in the instrument clus­
ter display is only an informational display. If
the oil level is too low, a minimum oil warning
appears in the instrument cluster. Add oil. If
the hood was opened, the current oil level is
shown in the instrument cluster the next time
the ignition is switched on.
