'SI: .... .... Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
11-Keep the sw itch<®) pulled and depress the ac­
celerator. The parking brake stays applied and
prevents the vehicle from rolling backward .
11-You can release the switch© once you are su re
that you a re deve loping enough forwa rd mo­
mentum at the whee ls as you depress the ac­
celerator .
Depending on the weight of the rig (vehicle and
trailer) and the seve rity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch C®> pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake.
Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the sw itch<®) and contin­
ue to pull it to s low your vehicle down with the
parking brake.
11-As soon as you release the switch © or acceler-
ate, the brak ing process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking function is in itiated. The vehicle is braked
at all four wheels by activating the hydrau lic
brake system . The brake performance is sim ilar
to making an emergency stop¢,& .
In order not to activate the emergency brak ing by
mistake, an audib le warning tone (bu zzer)
sounds when the sw itch(®) is pu lled . As soon as
the switch(®) is released, or the accelerator pedal
i s depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
fai led or the brake pedal is obstructed. Using
t he parking brake to perform emergency
braking will slow your vehicle down as if you
D riving
had made a full brake applicat ion . The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDL). In corners and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end to
b reak away -risking an acc ident.
Start/Stop system
Description
Applies to: vehicles with Start-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO2 emissions.
In the Start-Stop-mode, the engine shuts off au­
tomatica lly when the vehicle is stopped, such as
at a traffic light . The ign ition remains switched
on during this stop phase. The eng ine will be au­
tomat ically restarted when needed.
The last Start-Stop-System setting (on/off using
the b utton
10 -I) will be restored when the igni­
t ion is turned on. The LED in the
10 ~1 button turns
on when the Start-Stop-System is switched off
manually .
Basic requirements for the Start-Stop mode
-The driver's door is closed.
- The driver' seat belt is latched .
- The hood is closed.
- The vehicle must have bee n driven faster than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle .
A WARNING

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 items using the tie-downs pro­
vided
¢ page 68, Luggage compartment .
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 lead ing to serious personal injury:
- Always keep in m ind 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 .

Child safety
The airbag on the passenger side makes the front
seat a potentially dangerous p lace for a child to
ride. The front seat is not the safest place for a
child in a forward-facing child seat. It is a very
dangerous place for an infant or a larger child in
a rearward-fac ing seat.
A WARNING
Not using a ch ild safety seat, using the wrong
child safety seat or improperly installing a
child restra int increases the r isk of serious
personal inju ry and death in a crash.
- Never install rear-facing chi ld safety seats
or infant carriers on the front passenger
seat -even with an Advanced Airbag System.
A chi ld will be seriously injured and can be
killed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest,
door or roof
c::, page 147, Child restraints on
the front seat -some important things to
know.
- Always install rear-facing child safety seats
or infant carr iers on the rear seat.
- Never install a rear-facing child restra int in
the forward-facing direct ion. Such restraints
are designed for the spec ial needs of infants
and very sma ll children and cannot protect
them properly if the seat is forward-fa cing.
- If you must install a rearward fac ing ch ild
safe ty seat on the front passenger seat be­
ca use of exceptiona l circumsta nces and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
the rear-facing chi ld safety seat in a rear
seat ing position and have the airbag system
inspected by your Audi dealer.
-Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used

Convertible child safety seats
Properly used convertible child safety seats can
help protect toddlers and children over age one
who weigh between 20 and 40 lbs. (9 and 18 kg)
in a crash.
Fig . 1 7 5 Schemat ic overv iew : installat ion of the attach ­
ments applicable to a LA TCH seat
Fig. 176 Schemat ic overv iew: i nstallat ion of the seat using
the vehicle's safety belt system
.. When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertib le locking retractor on the safety belt
to prevent the child safety seat from moving
c:> page 177 or install the seat using the LATCH
attachments .
.. Push the chi ld safety seat down wi th your full
we igh t to get the safe ty belt really tight so that
the seat cannot move forward or sideways
more than one inch (2 .5 cm)
c:>page 177.
.. If the child safety seat is equipped with a tether
strap, attach it to the tether anchors
c:>page 184.
.. Secure unused safety belts on the rear seat
c:>page 173.
A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs. (9 kg). ..,.

Child safety
-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
being used ¢
page 168. Special precautions
apply when installing a child safety seat on
the front passenger seat¢
page 147, Child
restraints on the front seat- some impor­
tant things to know.
178
A WARNING , .
Always take special precautions if you must
install a forward or rearward-facing child re­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward-facing child restraint is installed on the front pas­
senger seat, the
PASSENGER AIR BAG OFF
light must come on and stay on whenever
the ignition is switched on.
- If the PASSENGER AIR BAG OFF light does
not come on and stay on, perform the
checks described¢
page 156, Monitoring
the Advanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
- An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier .
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash.
A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag .
- Never put the forward-facing child restraint up, against or very near the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
-

adjustment range, as far away from the air­
bag as possible before installing the for­
ward-facing child restraint. The backrest must be adjusted to an upright posit ion .
- Make sure that the
PAS SEN GER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on .
A WARNING
Rearward-facing child restraints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and chi ld
against the backrest, center armrest, door
or roof.
- Always be especially careful if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight-mat in the seat and register a heavi ­
er weight in the Advanced Airbag System .
The heavier weight registered can make the system work as though an adult were on the
seat and deploy the Advanced Airbag when
it must be suppressed causing serious or
even fatal injury to the child.
- Make sure that the
PASSENGER AIR B AG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
sta ll the rear-fac ing ch ild safety sea t in a
rear seating position and have the airbag
system inspected by your Audi dealer.

To avoid fuel spill ing o r evaporating from the f uel
tank always close fuel filler cap properly and
comp let ely. An improperly closed fue l filler cap
may a lso caus e the MIL lamp ¢
page 28 to come
on (only vehicles with gasoline engine).
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly f lammable and can cause se­
vere burns and other injur ies.
-
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump no zzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fue l can cause a fire .
- Never use a cellular telephone wh ile refuel­
ing . The electromagnetic radiation can
cause spa rks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling .
If in except io na l circumstances you
must get back in you r vehicle while refue l­
ing, make certain tha t you close the door
and touch meta l to discharge static electric­
ity before touchi ng the filler nozz le again.
Static electricity can ca use spa rks that can
ignite fuel vapors released during refueling .
- Never smoke o r have an open flame any­
where in or near your vehicle when refueling or filling a portable f uel container.
- For yo ur safety , we strongly recommend
that you do not travel with a portable fue l
conta iner in your vehicle. The conta iner, full
or empty may leak and could cause a fire,
especially in a crash .
-If, under exceptional c ircumstances, you
must transport a portable fuel container,
please observe the follow ing :
- Neve r fi ll a portable fuel containe r wh ile i t
is anywhere in or on the vehicle (for exam ­
p le, in the luggage compartment, or on

Selective catalytic reduction (Ad Blue)
General information
Applies to: vehicles with selective catalytic reduction (SCR)
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions .
The Ad Blue is carried in a separate tank in the ve­
hicle. The AdBlue usage accounts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used.
When a message about Ad Blue appears in the in­
strument cluster display, you must refill the
Ad Blue yourself or have it refilled by an author­ ized Audi dealer or author ized Audi Service Facili­
ty
¢ page 217.
@ Tips
-The instrument cluster display indicates the
distance remaining that can be driven
¢page 216. If the AdBlue tank is com­
pletely empty , the eng ine will not start
again after the ign ition is switched off.
- Ad Blue is required by law to operate th is ve­
hicle.
