\.J ' During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it
is locked -especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D) Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking
brake releases automatically and your vehicle
starts to move
c::> page 75.
(D Tips
- Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
Driving
- If there is a power failure, the parking brake
will not set if it is released, and it will not
release if it is set

Audi dealer or authorized Audi Service Fa­
cility for assistance.
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver's door must be closed
and the driver's safety belt must be fastened.
.,. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­ er is maintained for a brief moment
c::> ..&. to pre ­
vent the vehicle from rolling back when starting .
During this time, you can easily begin to move
your vehicle.
_& WARNING
A ppl ies to: ve hicles with hill hold assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately .
- The intelligent technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks.

- Please note that a small amount of power is
tra nsmi tted if the vehicle is stoppe d tem po­
rari ly wh ile in the D/S or R sele ctor leve r po­
sitio n. T o reduce the ris k of an ac cident, you
m ust c ontin ue pressing firm ly on the brake
pe dal while the ve hicle is stopped so that it
does not roll.
- Never engage the R or P selector level pos i­
tion s while dr iving. It could ca use a crash .
- Before driving down a s teep slope, redu ce
your speed and sh ift into a lower gear w ith
"t i p tronic" .
- Do not ri de the brakes or press the brake
pe dal too often or too long when dr iv ing
downhill . Constant braking causes t he
brakes to ove rheat and substant ia lly re­
duces brak ing performance, increases brak­

\.J ' -Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving . Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of veh icle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
stowed and secured in the luggage compart­
ment.
L oose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma­
neuver or in a collision.
.. Distribute the load evenly in the luggage com­
partment.
.. Always place and properly secure heavy items in
the luggage compartment as far forward as
possible.
.,. Secure luggage using the tie-downs provided
¢ page 55 .
.,. Make sure that the rear seatback is securely
latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment using the tie-down hooks and
suitable straps.
Driving safety
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the
luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and handle differently.
- Please observe information on safe driving
¢page 129.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving .
- Never transport objects larger than those
f itting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
A WARNING
Always make sure that the doors, all win­
dows , the power roof* and the rear lid are se­
curely closed and locked to reduce the r isk of
in jury when the vehicle is not being used.

\.J ' -Therefore, always wear your safety belts and
make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel with both
hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in­
jury if the driver's airbag inflates .
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
& WARNING
Objects between you and the airbag will in ­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
- Always make sure nothing is in the front air-
-
bag deployment zone that could be struck
by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked ,,AIRBAG" on
the steering wheel, instrument panel or the seat backrests; never place them between
these areas and you or any other person in
the vehicle .
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in­
jury in a collision, especially when the air­ bags inflate .
Airbag system
-Never recline the front passenger seat to
transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­
den maneuver. Objects near the airbags can
fly dangerously through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
& WARNING
= -
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­ ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
= The Advanced Airbag System can deploy in
accordance with the .,low risk" opt ion for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­ itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­
hicle was certified is on the front passenger
seat and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standard ..,.

A WARNING -
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.
- 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 collision.
- Always make sure that the rear seat back­
rest to which the center rear safety belt* is
attached is securely latched whenever the
rear center safety belt is being used to se­
cure a child restraint.
- If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will
strike parts of the vehicle interior. The child
can be seriously injured or killed.
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates.
- The inflating airbag will hit the child safety seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats or infant carriers on the rear seat.
- Forward -facing child safety seats or infant
carriers installed on the front passenger's
seat may interfere with the deployment of
the airbag and cause serious injury to the
child.
- It is safer to install a forward-facing child
safety seat on the rear seat.
-Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see
~ page 195 .
You can find the fuel tank capacity of your vehicle in
~ page 262 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For mo re in­
formation about fuel specifications , see
~ page 191 .
You r vehicle fuel tank has an onboa rd refuelling
vapor recovery sys tem . 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 follow this
refueling procedure carefully.
_& WARNING
Under norma l 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 regarding 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. The irregular supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalyt ic
converter.

Checking and Filling
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ~ page 262.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp~
page 25 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries .
- Fuel ignites easily and can cause serious burns and other injuries .
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling . If
you must make an exception and enter your
vehicle again while fueling, close the door
and touch metal to discharge static electric­ity before touching the fuel nozzle . Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion.
- Always place a fuel container on the
ground before filling.
- Always hold the fuel nozzle completely in
the fuel container when filling.
194
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex ­
plosive and increases the risk of serious in­
jury or death .
- Follow legal requirements when using, storing and transporting fuel containers .
- Make sure the fuel container conforms to industry standards (ANSI/ASTM F852-86).
(D Note
-Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter .
(D Note
Applies to: vehicles with diesel eng ines
If the fuel tank runs completely empty, the
ignition must remain switched on for at least
30 seconds after refueling before starting the
engine. It may take longer than usual for the
engine to start, even up to a minute. This is
because the air must first bleed out of the
fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(y Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside.
(D Tips
Applies to: veh icles with diesel e ngin es
Diesel vehicles are equipped with a misfueling
guard
l) . It allows the vehicle to be fueled on-
ly with a diesel fuel pump nozzle . .,.

-A worn or damaged nozzle or a nozz le that
i s too sma ll may not be ab le to open the
diesel misfueling guard. If this is the case,
try turning the nozzle before insert ing it in
the fue l fi ller neck, use a different fuel
pump, o r see an a uth orized Audi dea ler or

Selective catalytic reduction (AdBlue/DEF)
General information
Appl ies to: vehicles with selective catalytic reduct io n
In vehicles with selective catalyt ic reduction, a
urea sol ution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
converter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or DEF (Diesel Ex­
haust F luid) . Ad Blue is used in the fo llow ing .
The Ad Blue is carried in a separate tank in the ve­
hicle . The AdBlue usage acco unts for app rox i­
mately 0 .5% to 2.5% of the diesel fuel that is
u sed .
When a message about refi lling the AdBlue ap­
