Sitting correctly and safely


— If you use a forward-facing child safety seat
on the front passenger's seat, move the seat
as far back as possible so that it is as far as
possible from the front passenger's airbag.
While doing this, make sure the seat can be
adjusted all the way. A child in a child safety
seat on the front passenger's seat can re-
ceive a severe impact if the front passeng-
er's airbag deploys, which increases the risk
of serious or fatal injury.
— Replace the child safety seat after an acci-
dent because there could be damage that is
not visible.
— Even if a child is not sitting in the child safe-
ty seat, the child safety seat must be se-
cured. An unsecured child safety seat may
be thrown through the vehicle interior dur-
ing sudden braking maneuvers or an acci-
dent.

Correct positioning for children
Always secure children ina child safety seat de-
signed for the body size, weight, and age of the
child.
You can secure child safety seats in your vehicle
using the safety belts.
Applies to Coupe: You can also secure child safety
seats to the LATCH anchors and to the top tether
anchors. Depending on the child safety seat, it
may also be necessary to secure it to the top
tether anchor. In Canada, it is required by law to
secure forward-facing child safety seats to the
top tether anchors on the rear seats.
Applies to: Roadster: There are no top tether an-
chors installed in your vehicle. Do not use any
child safety seats or booster seats that require
top tether anchors.
Always transport children in the rear seats
Applies to: Coupe
Accident statistics show that children that are se-
cured correctly in the rear seats are safer than in
front seats. Always transport children in suitable
child safety seats secured on the rear seats.
Children in the front passenger's seat
If you use a child safety seat on the front passen-
ger seat, then the front passenger’s airbag must
be deactivated. Please note the important infor-
mation for this > page 55, Advanced airbag sys-
tem. If you must secure a forward-facing child
safety seat, move the front passenger's seat as
far back as possible so that it is as far as possible
from the front passenger's airbag. While doing
this, make sure the seat can be adjusted all the
way.
Only switch to a larger child safety seat when
absolutely necessary
Switch to a larger child safety seat only when ab-
solutely necessary. Secure your child using a safe-
ty belt without a child safety seat only if all of the
following statements are true:
— The child is large enough to sit upright in the
seat
— The child is able to sit with his or her back rest-
ing completely on the seat backrest
— The child is able to sit with his or her knees
bent over the edge of the seat surface
— The child is able to sit with both of his or her
feet completely touching the floor in the foot-
well
— The lap portion of the safety belt lies flat and
securely over the hip area and never over the
stomach
— The shoulder portion of the safety belt lies flat
and securely over the center of the shoulder
and the chest, and never under the arm, behind
the back, or over the neck or face.
—The child is able to maintain this seating posi-
tion throughout the entire trip
Read and follow the important information and
warnings regarding the correct use of safety
belts > page 49.
G) Tips
— Child safety seats can also be secured to
seats with side airbags. In the event of an
accident, children can also be protected by
the side airbags if the child is correctly se-
cured ina suitable child safety seat that is
attached correctly.

Sitting correctly and safely

— Applies to: Coupe: The lower LATCH anchors
as well as the safety belt may be required to
correctly install some child safety seats. Us-
ing both at the same time is permitted, pro-
vided that the fastening systems or safety
belts do not impair those in an adjacent
seating position.
— All child safety seats are constructed so that
they can be secured using the lap safety belt
in the vehicle.

Fig. 63 Rear bench seat: lower LATCH anchors
Observe the safety precautions > page 57.
In the United States and Canada, child safety
seats can be secured without safety belts using
the LATCH system. LATCH stands for Lower An-
chors and Tethers for Children. In Canada, similar
systems are called UCRA, LUAS, or UAS.
The Lower LATCH anchors in your vehicle are lo-
cated on the seats of the rear bench seat be-
tween the seat surface and the backrest. These
seating locations each have two lower LATCH an-
chors that can be used to secure a LATCH child
safety seat. Marking points with a > fig. 63 sym-
bol are located on the covers for the lower LATCH
anchors. You can locate the LATCH anchors using
the marking points.
> Remove the covers from both LATCH anchors.
> Secure the unused safety belt that is within
range of the child. To do this, fasten the safety
belt for the seat where the child safety seat will
be installed. Activate the belt retractor lock on
the fastened safety belt. To do this, pull the up-
60
per belt out completely and then allow it to re-
tract. You will hear a clicking sound while the
belt is retracting. It will not be possible to pull
the safety belt out any farther.
> Make sure the fastened safety belt does not
block access to the LATCH anchors. Otherwise,
it may not be possible to secure the child safety
seat to the LATCH anchors correctly.
>» Secure the child safety seat according to the
child safety seat manufacturer instructions.
> Pull on the child safety seat to check if both
sides are engaged correctly in the LATCH an-
chors.
> If possible, also secure the child safety seat to
the respective top tether anchor in the vehicle
=> page 62.

ZX WARNING
— The LATCH anchors in the vehicle are only
designed for child safety seats with the
LATCH system. To reduce the risk of serious
or fatal injury, never secure other child re-
straint systems, belts, or objects to the an-
chors.
-Achild in a child safety seat could play with
the unused safety belts and then become
entangled in them, which increases the risk
of fatal injury. Always secure the unused
safety belt so that it is not within reach of
children in child safety seats.

G) Tips
The LATCH anchors are designed for a total
weight (child and child safety seat combined)
up to 65 lbs (29 kg). If the total weight is
greater than this, the child safety seat must
be secured with the vehicle safety belt.
Securing child safety seats with a safety
rit
Observe the safety precautions > page 57. The
front passenger’s seat is a dangerous location for
a child, even with an advanced airbag system. If
you use a rear-facing child safety seat on the
front passenger’s seat, the front passenger’s air-
bag must be deactivated. Please note the impor-
tant information for this > page 59, Correct >

Securing child safety seats
> If you secure a child safety seat to the front
passenger's seat, adjust the front passenger's
seat to the highest position.
>» Secure the child safety seat according to the
child safety seat manufacturer instructions.
> If necessary, activate the belt retractor lock
=> page 67.
> If the child safety seat is secured on the front
passenger's seat, adjust the front passenger's
seat backrest until it rests flat against the child
safety seat. Also make sure that the upper safe-
ty belt fixture is behind the child safety seat.
> Applies to: Coupe: If you secure a child safety
seat on the rear seat, also secure it to the cor-
rect top tether anchor if possible > page 62.
Activating the belt retractor lock
If you secure a child safety seat using the vehicle
safety belt, you must activate the belt retractor
lock. Follow the child safety seat manufacturer
instructions.
The belt retractor lock prevents the safety belt
from becoming loose while driving, which could
result in the child safety seat no longer being ad-
equately secured.
> Secure the child safety seat according to the
child safety seat manufacturer instructions.
While doing so, pull out the safety belt. Insert
the safety belt into the belt latch that belongs
to that seat until it audibly locks.
> Pull the upper belt out completely and then al-
low it to retract. You will hear a clicking sound
while the belt is retracting. It will not be possi-
ble to pull the safety belt out any farther.
> Push the child safety seat into the seat and al-
low the belt to retract more.
> Make sure that the child safety seat cannot
move more than 1 inch (2.5 cm).
Deactivating the belt retractor lock
> Unbuckle the safety belt from the belt latch.
> Remove the child safety seat according to the
manufacturer instructions.
> Allow the safety belt to retract completely. The
belt retractor lock is deactivated.

Z\ WARNING
— A safety belt that is not locked by the belt
retractor lock or a locking device cannot se-
cure a child safety seat while driving or in
the event of an accident, which increases
the risk of fatal injury. Always make sure the
belt retractor lock on the safety belt is acti-
vated if the child safety seat manufacturer
instructions require it.
— Due to the risk of fatal injury, never place a
rear-facing child safety seat on the front
passenger's seat when the front passenger's
airbag is switched on.
—For the child safety seat to offer the maxi-
mum protection, it is especially important
to route the vehicle safety belt correctly. Al-
ways follow the instructions from the child
safety seat manufacturer for routing the
safety belt correctly. Incorrectly fastened
safety belts can cause injuries, even during

minor accidents.

Storage and convenience


— Never drive with containers that contain hot
liquid such as coffee or tea. The hot liquid
could spill and cause burns during a colli-
sion, sudden braking or other vehicle move-
ment. Spilled hot liquid can also increase
the risk of accidents and injuries.
— Only use soft containers in the cup holders.
Hard cups and glasses can increase the risk
of injury during a collision.
— Never use the cup holder or the adapter as
an ashtray because this is a fire hazard.

@) Note
Beverage containers in the cup holders should
always
have a lid. Otherwise, the liquid inside
could spill and cause damage to vehicle
equipment.
Storage areas and
compartments
Depending on vehicle equipment, there are a va-
riety of storage areas, compartments, and retain-
ers, such as the glove compartment, for safely
storing and securing objects.

ZA\ WARNING
—To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or
objects in the vehicle.
— Applies to: Coupe: No heavy or hard objects
may be placed on the storage compartment
behind the rear seat backrest. There is a risk
of
injuring the vehicle passengers when
braking suddenly.

64
— Applies to: Coupe: Only lightweight clothing
should be hung from the garment hooks in
the vehicle. Do not use clothes hangers to
hang clothing. The pockets of the clothing
must not contain any heavy, breakable, or
sharp-edged objects. This could impair the
effectiveness of the side curtain airbags.
() Note
Applies to: Coupe

Make sure that the heating grid strips for the
rear window defogger are not damaged by
abrasive objects.
Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
» Use non-elastic cords attached to the tie-downs
to secure objects.

ZX WARNING
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured to
the tie-downs with unsuitable or damaged
straps, this can increase the risk of injury
during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.

Intelligent Technology

Intelligent Technology
Electronic Stabilization
Control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the motor torque is reduced
in order to stabilize the vehicle. When the ESC
engages, the B indicator light flashes in the in-
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake assist
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
104
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this

Image recording
Surrounding area monitoring
Applies to: vehicles with surrounding area monitoring
Some vehicle functions require the vehicle’s path
to be detected and evaluated. This is done by
cameras installed permanently on the vehicle
that detect objects in the vehicle's surroundings
(such as obstacles or guard rails). The live images
from the cameras are transmitted to the applica-
ble control module.
The camera images are transmitted to the appli-
cable control module and stored for processing.
The control module analyzes the current camera
image using image evaluation software. This im-
age evaluation software detects anonymized
technical measurements, such as distances to ob-
jects. The control module evaluates these techni-
cal measurements and makes it possible for the
assist systems to control the vehicle, if necessary.

Board Diagnostic System (OBD)
Your vehicle is equipped with electronic control
modules for various vehicle systems such as the
256

airbags. These vehicle control modules store data
while driving normally that is required by an au-
thorized Audi dealer or authorized Audi Service
Facility for diagnosis and repair purposes. Only
certain types of data are recorded for a very short
period of time if a control module has detected a
system event. No noises, conversations, or im-
ages will be recorded in the vehicle.
The data may include information such as the ve-
hicle speed, the direction of travel, and informa-
tion about the brake system, or also the behavior
of the restraint system in the event of an acci-
dent. The stored data can be exported and down-
loaded with special devices, which must be con-
nected directly to the vehicle.
On Board Diagnostic System (OBD)
There is a diagnostic connector socket in the driv-
er's side footwell to read out the various control
modules and the event data recorder. Data re-
garding the function and condition of the elec-
tronic control modules is stored in the event
memory. Only have an authorized Audi dealer or
authorized Audi Service Facility read out and de-
lete the event memory.

ZA\ WARNING
— Incorrect use of the connection port for the
On Board Diagnostic System can cause mal-
functions, which can then result in accidents
and serious injuries.
— Only allow an authorized Audi dealer or au-
thorized Audi Service Facility to read out the

Accessories and technical changes

Usually maintenance and repair work requires
special tools, measuring devices, and other
equipment that is available to trained vehicle
technicians in order to help ensure that your vehi-
cle and all of its systems operate correctly, relia-
bly, and safely. Performing work on the vehicle
incorrectly can impair the operation and reliabili-
ty of your vehicle and may void one or more of
your vehicle's warranties.
Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.


— Never perform any work in the motor com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
— If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from improperly per-
formed work.


Z\ WARNING
Maintenance work, repairs, or technical modi-
fications to the vehicle (such as installing ad-
ditional equipment) that is not performed
correctly can cause serious injuries and in-
crease the risk of an accident.


ZA\ WARNING
The motor compartment in any motor vehicle
is a potentially dangerous area and can cause
serious personal injury.
— Always use extreme caution when doing any
work in the motor compartment. Always fol-
low commonly accepted safety practices and
use common sense. Never risk personal in-
jury.
