ZA WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.


Fuel level
The display @ > page 10, fig. 3 only works when
the ignition is switched on. When the display has
reached the reserve mark, a red LED turns on and
the iy indicator light turns on > page 198.
For the tank capacity in your vehicle, refer to the
Technical Data > page 264.
@) Note
Never drive until the tank is completely emp-
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom-
busted fuel will then enter the exhaust sys-
tem. This can cause overheating and damage
to the catalytic converter.

Do not switch the ignition off because you may
not be able to switch it on again.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
& Engine start system: malfunction! Please
contact Service
There is a malfunction in the engine start system.
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
*\ Engine stop while driving
If the S indicator light turns on, there may bea
malfunction in the engine or fuel supply.
More force is needed to steer and brake the mov-
ing vehicle when the engine is stopped. If the ve-
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.

ZA\ WARNING
If the engine stops while driving, you will need
to use more force to brake the vehicle. This in-
creases the risk of an accident. There will still
be power steering if the ignition is switched
on while the vehicle is rolling and there is suf-
ficient battery charge. Otherwise, you must

use greater force when steering.

53/8 Electronic Stabilization Control (ESC)

If the B indicator light blinks while driving, the
ESC or ASR (Anti-Slip Regulation) is actively regu-
lating.
If the BB indicator light turns on, the system has
switched the ESC off. In this case, you can switch
the ignition off and then on to switch the ESC on
again. The indicator light turns off when the sys-
tem is fully functional.
If the [J indicator light turns on, ESC was
switched off using the |2%] button > page 705.


Stabilization control (ESC/ABS): malfunction!
See owner's manual
If the B indicator lamp and the ES / Gass in-
dicator lamp turn on and the driver message ap-
pears, the ABS or electronic differential lock is
malfunctioning. This also causes the ESC to mal-
function. The brakes still function with their nor-
mal power, but ABS is not active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
@ Tips
For additional information on ESC and ABS,
see > page 104.
If the B indicator light turns on if there is a mal-
function in the engine control. Drive slowly to an
authorized Audi dealer or authorized Audi Service
Facility to have the engine checked.
§ Suspension control
Applies to: vehicles with Audi drive select
If the | 8 | indicator light turns on, then there is a
malfunction in the suspension control. Drive im-
mediately to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
repaired.

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.

Driving

Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button.


Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To stop the engine, press the
START ENGINE STOP] button twice in a row or


press and hold it one time.

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.

Driving

Parking
> Press the brake pedal to stop the vehicle.
> Pull the ©) switch to set the parking brake.
> Place the selector lever in the “P” position.
> Turn the engine off > /A\.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.

Z\ WARNING
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— Emergency braking should only be used in
an emergency, when the when the standard
brake pedal is malfunctioning or obstructed.
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 once it is released. In this
case, park the vehicle on level ground and
secure it by placing the selector lever in the
P position. See an authorized Audi dealer or
authorized Audi Service Facility for assis-
tance.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise children could start
the engine, release the parking brake or op-
erate electrical equipment such as power
windows, which increases the risk of an acci-
dent.
— 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.

80
@) Note
Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
@) Tips
— Noises when the parking brake is set and re-
leased 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.
Starting to drive
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.
> 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
If you take your foot off of the brake pedal when
driving on hills, the braking force will be held for
several seconds. At that time, you can start driv-
ing without the vehicle rolling backward.
Requirement: the driver's door must be closed,
the engine must be on, and the vehicle must be
traveling uphill.
> To activate hill hold assist, press and hold the
brake pedal for several seconds while the vehi-
cle is stationary.

ZA\ WARNING
—To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is >

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

can affect driving stability and increase the
risk of a collision.

@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in motor power.
— You may hear noises when the systems de-
scribed are working.
Sica Re meal
The ESC is automatically switched on when the ignition is switched on.

The ESC is designed to function in levels. Depend-
ing on the level that is selected, the stabilization
function of the ESC will be limited or switched
off. The amount of stabilization control will differ
depending on the level.
The following examples are unusual situations
where it may make sense to switch sport mode
on in order to allow the wheels to spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow or on loose ground
— Driving with snow chains







You should only switch sport mode on or
switch ESC/ASR off if your driving abilities and
road conditions permit.
— The stabilization function is limited when
sport mode is switched on. The driving
wheels could spin and the vehicle could
swerve, especially on slick or slippery road
surfaces.

Brakes
(eee eleurl sel)
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake sys-
tem is cleaned at regular intervals. This is done
by applying the brake pads to the brake rotors for
a short period of time when driving at high
speeds when the windshield wipers are switched
on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 miles (400 km). They
must be “broken in” first. However, you can com-
106
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.

ZA\ WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not
place your foot under the brake pedal.
@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.

8S1012721BE
Intelligent Technology

— Utilize the engine braking effect when driv-
ing downhill by selecting the “S” driving
program > page 82. This reduces the load
on the brakes. If you need to brake addition-
ally, brake in intervals and not continuously.
G) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 209.
