If you are transporting children in the vehicle,
read the information and follow the safety
precautions > page 57.
Safety systems monitoring
The ka indicator light in the instrument cluster
monitors the safety systems such as the airbags
(including the control modules, sensor, and wir-
ing) and the belt tensioners. It turns on when you
switch the ignition on and turns off after several
seconds.
If the indicator light does not turn on when the
ignition is switched on, does not turn off after
several seconds, or turns on or flashes while driv-
ing, there may be a malfunction in one of the
safety systems. Drive to an authorized Audi deal-
er or authorized Audi Service Facility immediately
to have the malfunction corrected.
ZA\ WARNING
Have the malfunction in the safety systems in-
spected immediately. Otherwise, there is a
risk that the systems may not activate during
an accident, which increases the risk of seri-
ous or fatal injury.

Sitting correctly and safely
The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
Driver's airbag
Front passenger's airbag
Side airbags
Applies
to: Coupe: Head curtain airbag with
ejection mitigation

Knee airbags
Airbags offer the best possible protection in your
vehicle during an accident when they are used to-
gether with safety belts that are fastened cor-
rectly, and when passengers are sitting in the
correct seating position. Airbags are a supple-
mentary restraint system and do not replace
safety belts.
Applies to: Coupe: Airbags may deploy during
head-on, side-impact, or rollover collisions.
Applies to: Roadster: Airbags may deploy during
head-on or side-impact collisions.
The deployment area for the airbag system can-
not be defined for every situation, since the cir-
cumstances surrounding accidents can vary wide-
ly. Factors that play an important role include the
condition of the object that the vehicle hits (hard
or soft), the angle of impact, vehicle speed, etc.
The deciding factor for the deployment of the air-
bag system is the deceleration that occurs during
an accident. Sensors in the vehicle are designed
to detect the severity of an accident in conjunc-
tion with the control module, and to provide a
targeted and timely deployment of the restraint
system. If the vehicle deceleration that is meas-
ured during an accident is below the specified
reference values in the control module, then the
airbags will not deploy, even though the vehicle
may be severely damaged from the accident. In
these cases, the vehicle occupants will be pro-
tected by the safety belts if they are fastened and
worn correctly.
The deployment of the front passenger's airbag
will depend on the occupancy of the seat
=> page 55.
Each deployed airbag is filled with gas. When this
occurs, the airbag covers open and the airbags
unfold with great force into the deployment zone
within milliseconds. Inflated airbags reduce the
movement of passengers wearing safety belts in
the direction of the impact and thus help to re-
duce the risk of injury. They can help to protect
the head, upper body, and lap, for example. How-
ever, there is the possibility that airbag deploy-
ment can cause injuries.
The airbag system only works when the ignition
is turned on.
If you or other vehicle passengers have physical
limitations that prevent sitting in a correct posi-
tion, modifications to the vehicle may be neces-
sary. For more information, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty, or call Audi customer support at
1-800-822-2834.
) Tips
Applies to: Coupe
The side curtain airbags in your vehicle have
ejection mitigation functions. This reduces
the risk of being ejected from the vehicle inte-
rior during an accident, especially in the event
of a vehicle rollover.
Advanced airbag system
Fig. 62 Headliner: indicator light to display the status of
the front passenger's airbag
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of the United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to these requirements, the front Ad-
vanced Airbag System on the passenger’s side

Sitting correctly and safely
Always make sure the indicator light corresponds
to the occupancy of the front passenger's seat.
— An adult or individual of similar size in the
front passenger's seat: the front passenger's
airbag must be activated, therefore
PASSENGER AIR BAG ON @ must remain
turned on.
— An individual of smaller size (for example, an
adolescent or small adult) in the front pas-
senger's seat: the front passenger's airbag
must be activated, so
PASSENGER AIR BAG ON ® must stay on.
— Child in a child safety seat on the front pas-
senger's seat: the front passenger's airbag
must be deactivated, so
PASSENGER AIR BAG OFF #; must stay on.
— Front passenger's seat not occupied: the front
passenger's airbag must be deactivated, so
PASSENGER AIR BAG OFF $; must stay on.
Z\ WARNING
— An adult or a person with a small stature
(such as a young person or small adult) seat-
ed on the front passenger's seat will not be
protected by the passenger's airbag in the
event of a collision if the passenger's airbag
is deactivated. This increases the risk of in-
jury and death. Always make sure that
PASSENGER AIR BAG ON @ remains on
while driving. If
PASSENGER AIR BAG ON @ does not
turn on, make sure the front passenger is
sitting correctly in the seat > page 45 and
that there is nothing covering the front pas-
senger's seat (such as blankets or pillows). If
PASSENGER AIR BAG ON @ still does
not turn on, the front passenger's seat must
not be used. Drive to an authorized Audi
dealer or authorized Audi Service Facility
and have the airbag system inspected.
—Achild ina child safety seat on the front
passenger's seat - especially in a rear-facing
child safety seat - can receive a severe im-
pact if the front passenger's airbag deploys,
which increases the risk of serious or fatal
injury. Applies to Coupe: Always secure child
safety seats on the rear seats. If special cir-
cumstances require the use of a child safety
seat on the front passenger's seat, always
make sure that
PASSENGER AIR BAG OFF &%; stays on
while driving. If
PASSENGER AIR BAG OFF #%; does not
turn on, remove the child safety seat and in-
stall it again according to the child safety
seat manufacturer instructions. If
PASSENGER AIR BAG OFF &%; still does
not turn on, the front passenger's seat must
not be used. Drive to an authorized Audi
dealer or authorized Audi Service Facility
and have the airbag system inspected.
— Fluids, electronic devices, or mechanical
damage on the front passenger's seat may
cause the front passenger seat occupant de-
tection to malfunction. The system may
then incorrectly detect if the front passeng-
er's seat is occupied. As a result, it could de-
ploy the front passenger’s airbag incorrectly
or fail to deploy it, which increases the risk
of serious or fatal injury. Make sure that no
wet objects (such as a wet hand towel) and
no fluids come into contact with the front
passenger's seat cushion. If the front pas-
senger's seat becomes wet, dry it immedi-
ately. Make sure no electronic devices (such
as a laptop or a retrofitted seat heater) are
on the front passenger's seat. Do not trans-
port any objects on or under the front pas-
senger's seat.
— Seat covers or protective covers may prevent
the advanced airbag system from correctly
detecting child safety seats or passengers in
the front passenger's seat. You must not use
seat covers or protective covers on the front
passenger's seat that are not specifically ap-
proved for use on Audi seats with an ad-
vanced airbag system.
Child safety seats
General information
When installing and using child safety seats, fol-
low the information in this Owner's Manual, the
applicable state and federal regulations, and the

ZA\ WARNING
To reduce the risk of serious or fatal injuries,
children must always be secured in the vehicle
with a child safety seat that is appropriate for
their body size, weight, and age.
— Children ages 12 and under must be trans-
ported using the appropriate child safety
seat. Note differences in regulations be-
tween states and countries. Applies to
Coupe: Also follow the information about
the correct seating position on the rear
bench seat > page 48.
— Child safety seats secured incorrectly in the
vehicle may cause serious or fatal injuries in
the event of an accident. Always secure the
child safety seat according to the manufac-
turer instructions.
— Children or babies must not under any cir-
cumstances be held on the lap of the driver
or other passengers while driving.
— Do not secure more than one child in a child
safety seat.
— Never allow a child to sit in a child safety
seat unsupervised.
— Never allow children to ride unsecured in
the vehicle or to stand or kneel on the seats
while driving. In the event of an accident, a
child could be propelled through the vehicle.
58
This can cause serious or fatal injuries for
the child and passengers.
— If children use an incorrect seating position
while driving, they have a higher risk of in-
jury during a sudden braking maneuver or
accident. This especially applies to children
in the front passenger's seat or children who
have their head near the side airbag deploy-
ment area, if the airbag system is deployed
during an accident. This incorrect seating
position can cause severe or even fatal inju-
ries.
— Applies to: Coupe: Make sure there is
enough space in front of the child in the
child safety seat. If necessary, adjust the an-
gle and position of the seat in front of the
child safety seat.
— The rear side of a forward-facing child safety
seat should be positioned as close as possi-
ble to the backrest on the vehicle seat.
— Applies to: Coupe:Always make sure that the
backrest on the seat where the child safety
seat is installed is securely locked in place
and cannot move forward. Otherwise, the
backrest where the child safety seat is se-
cured could move forward in the event of an
accident or other emergency situation.
— NEVER use a rear-facing child safety seat on
a seat with an ACTIVATED FRONT AIRBAG;
this could cause DEATH or SERIOUS INJURIES
toa CHILD.
— Applies to: Coupe: Always secure child
safety seats on the rear seats.
— If you use a child safety seat on the front
passenger seat, then the front passenger’s
airbag must be deactivated. Always make
sure that PASSENGER AIR BAG OFF %;
stays on while driving. If
PASSENGER AIR BAG OFF #, does not
turn on, remove the child safety seat and
install it again according to the child safe-
ty seat manufacturer instructions. If
PASSENGER AIR BAG OFF 2%; still does
not turn on, the front passenger's seat
must not be used. Drive to an authorized
Audi dealer or authorized Audi Service Fa-
cility and have the airbag system inspect-
ed.

Warm and cold
Warm and cold
Climate control system
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It functions most effectively when the windows
are closed. If there is a build-up of heat inside the
vehicle, ventilation can help to speed up the cool-
ing process.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
coolant has reached a certain temperature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
ZA WARNING
Poor visibility can lead to accidents.
— For safer driving, keep all windows free of
ice, snow and fog.
— Become familiar as quickly as possible with
the correct use and function of the climate
control system, especially with the defrost-
ing and defogging function.
— When the temperature is below freezing,
only use the windshield washer system after
the
windshield has been warmed by the cli-
mate control system. The washer fluid could
freeze on the windshield and impair visibili-
ty.
©) Note
— If you suspect that the climate control sys-
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
— Repairs to the Audi climate control system
require special technical knowledge and
special tools. Have it inspected by an au-
thorized Audi dealer or a qualified electron-
ics store.
(@) For the sake of the environment
Reducing the amount of fuel used also re-
duces the amount of pollutants that enter the
air.
G) Tips
—To prevent interference with the heating
and cooling output and to reduce the risk of
the windows fogging over, the air intake in
front of the windshield must be free of ice,
snow, or leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.
— The flows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug-
gage compartment cover.

@) Note
To reduce the risk of damage to the seat heat-
ing elements, do not kneel on the seats or
place heavy pressure on one area of the seat.
@) Tips
— The setting for the seat heating on the driv-
er's side is assigned to the key that is in use.
— If the front passenger's seat heating is
turned on, it will not turn on again automat-
ically if more than 10 minutes have passed
between switching the ignition off and
switching it on again.

The neck heating has three levels. If you turn the
knob to the right, the neck heating switches on
=> fig. 82. The LEDs above the seat symbol indi-
cate the ventilation level. Turn the knob to the
left to reduce ventilation. To switch off the neck
heating, keep turning the knob to the left until
no LEDs are turned on.
72
When the power top is closed, the neck heating
will switch automatically from setting 3 to set-
ting 2 after approximately six minutes.
ZA WARNING
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the neck heating. To reduce the risk of
injury, these individuals should not use neck
heating.
— The output from the neck heating may be-
come very hot temporarily if the air vents in
the seats > fig. 87 are covered by clothing
or similar objects when the system is switch-
ed on. This can cause burns on unprotected
skin exposed directly to the vents.
@ Tips
— The fan speed is always lower when the
power top is closed than when it is open.
— Energy management > page 109 may re-
duce the heat output if the battery voltage
is too low.

General information
Breaking in
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine and other drive com-
ponents.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
tion. The engine can be increased RPM gradually
during the next 300 miles (S00 km).
Trailer mode
® Note
Your Audi is not designed for towing a trailer.
Damage caused by towing a trailer is not cov-
ered by the warranty.
Reducing the risk of vehicle damage
@) Note
When driving on poor roads, over curbs, and
on steep ramps, make sure that components
that hang below the vehicle, such as the spoil-
er and exhaust system, are not struck because
they could be damaged. This especially ap-
plies
to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water
If you must drive through water, follow these in-
structions:
— Check the stability of the ground, the current,
and the water depth. If the ground is unstable,
there is a strong current, or there are waves,
the water must only reach up to the lower edge
of the body at the most.
— Deactivate the Start/Stop system*.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash
above the lower edge of the body. Oncoming
vehicles could also create waves.
— Do not stop the vehicle while in the water.
— Drive in reverse.
— Do not turn the engine off.
ZA WARNING
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
@) Note
Vehicle components such as the motor, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
ter
Gi) Tips
If possible, avoid driving through salt water
because it increases the risk of corrosion. Use
fresh water to clean any vehicle components
that come into contact with salt water.
Efficient and environmentally-friendly
driving
The amount of fuel consumption, the environ-
mental impact, and the wear to the engine,
brakes, and tires depends mostly on your driving
style. Note the following information for efficient
and environmentally-conscious driving:
— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not let the engine run while the vehicle
parked.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You may need to use more
force when braking or steering. Because you
cannot brake and steer as you usually would,
this could lead to accidents and serious inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@) Note
If the engine has been under heavy load for an
extended period of time, heat builds up in the
engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
@) Tips
For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again auto-
matically or it may continue to run, even if the
ignition is switched off.
