Some the equipment listed here is only instal-
led in certain models or is available as an op-
tion.
Indicator lights overview
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal-
functions. Some warning and indicator lights
turn on when you switch the ignition on and must
turn off when the drive system is switched on or
while driving.
With some indicator lights, messages may ap-
pear and warning signals may sound. The indica-
tor lights and messages may be covered by other
displays. To show them again, select the second
tab for messages with the multifunction steering
wheel > page 72.
Some indicator lights in the display can display in
several colors.
OMe ile Lins
If the A or A indicator light turns on, check the
message in the instrument cluster.
COAT
The following indicator lights may be available,
depending on the vehicle equipment:

8S1012721BE
Instrument cluster

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.

Driving

Driving
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.

Driving

appears in the instrument cluster once the en-
gine stops automatically.
> The engine starts again when you remove your
foot from the brake pedal. The indicator light
turns off.
Additional information for automatic
transmissions
The engine stops in the "P", "N" and "D" selector
lever positions.
If you select the “R” gear during a Stop phase
while pressing the brake pedal, the engine will
start again.
Shift to "P" quickly to prevent the engine from
starting unintentionally when shifting through
"RM.
You can control if the engine will stop or not by
reducing or increasing the amount of force you
use to press the brake pedal. For example, if you
only lightly press on the brake pedal in stop-and-
go traffic or when turning, the engine will not
switch off when the vehicle is stationary. If you
press the brake pedal harder, the engine will
switch off.
@) Tips
— Press the brake pedal during a Stop phase
to keep the vehicle from rolling.
— The ignition will turn off if you press the
START ENGINE STOP] button during a Stop


phase.
— When you stop and the Start/Stop system
turns the engine off, the ignition remains
on. Make sure the ignition is switched off
before you leave the vehicle or else the bat-
tery could drain.
General information
Applies to: vehicles with Start/Stop system
Starting and stopping the engine automat-
ically
The system checks if certain conditions are met
before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
78
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.
Ignition is switched off automatically
To prevent the vehicle battery from draining, the
ignition will switch off automatically under the
following conditions:
— If the vehicle has already been driven
— If the Start/Stop system has stopped the en-
gine
— If the driver's door is opened
— If the driver's safety belt is unbuckled
— If the brake pedal is not pressed
— If the vehicle is stationary
In this case, the parking lights switch on in place
of the low beams and the message Side marker
lights will switch off automatically in 30 mi-
nutes. See owner's manual appears in the Info-
tainment system display. The side marker lights
will switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start/Stop system has not turned off the
engine or if you have switched the Start/Stop sys-
tem off manually, the ignition will not be auto-
matically switched off and the engine will contin-
uetorun>A.

ZA WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
G) Tips
If you select the “D” or “N” selector lever posi-
tion after shifting into reverse, the vehicle
must be driven faster than 6 mph (10 km/h)
in order for the engine to switch off again.

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.
— If the power supply fails, you cannot set the
parking brake once it is released, or release
it if it is set. In this case, park the vehicle on
level ground and secure it by engaging the
"P” gear. Contact an authorized Audi dealer
or authorized Audi Service Facility for assis-
tance.

ZA WARNING
— If you do not begin driving immediately after
releasing the brake pedal, your vehicle may
begin to roll backward. Press the brake ped-
al or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,

on slippery or icy ground).

Sporty driving
Applies to: RS models
When driving in a sporty style, the wear on all ve-
hicle components is greatly increased, especially
on the engine, transmission, tires, brakes, and
suspension. This can result in increased wear. Al-
so
note the following points:
— Make sure the vehicle is in good condition.
Make sure to check the brake pads, tire tread,
and tire pressure (when tires are warm).
— Beforehand, warm up the engine by driving no
higher than two-thirds of the maximum permit-
ted engine RPM. The engine oil must be
brought to a minimum temperature of 158 °F
(60 °C).
— Before stopping the vehicle, allow the engine
and brakes to cool back down to a regular oper-
ating temperature by driving normally.
If necessary, use the following functions:
— Dynamic Audi drive select mode* > page 96
— Launch Control > page 86
— Limit ESC > page 105
@) Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically-
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the
vehicle to accelerate without a noticeable inter-
ruption in traction.
The transmission shifts up or down automatically
depending on which drive program is selected.
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a sporty driv-
ing style characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed, and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) > page 85.

Driving

P - Park
You can only shift into Park when the vehicle is
stationary > A.
To shift in and out of the P selector lever position,
press the interlock button in the selector lever
while pressing the brake pedal.
R - Reverse
Only shift into reverse gear when the vehicle is
stationary and the engine is running at idle
speed >A.
To select the R selector lever position, press the
interlock button while pressing the brake pedal.
The back-up lights switch on in the R position if
the ignition is switched on.
N - Neutral (idle)
The transmission is in idle in this position.
D/S - Normal position for driving forward
In the D/S selector lever position, the transmis-
sion can be operated either in the normal D mode
or in the S sport mode. To select the S sport
mode, pull the selector lever back briefly. Pulling
the lever back again will select the normal D
mode. The selected driving mode is shown in the
Infotainment display.
In the normal mode "D", the transmission auto-
matically selects the correct gear. It depends on
engine load, vehicle speed and driving style.
Select the sport mode "S" for sporty driving. The
vehicle makes full use of the engine's power.
Shifting may become noticeable when accelerat-
ing.
To move from selector lever position "N" to "D",
you must press the brake pedal and the vehicle
must be traveling less than 1 mph (2 km/h) or be
stationary > A.


— Never select "R" or "P" while driving, be-
cause this increases the risk of an accident.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except “P”) when the engine
is running. Otherwise, this increases the risk
of an accident.
— Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, even if the parking brake
is set. This could result in a crash.
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
— Never leave your vehicle with the engine
running while in gear. If you must leave your
vehicle when the engine is running, set the
parking brake and move the selector lever to
the "P" position.
— To decrease the risk of an accident, the se-
lector lever must be in the P position and
the parking brake must be set before open-
ing the hood and working ona running en-
gine. Always read and follow the applicable
warnings > page 200, General information.


Z\ WARNING
Read and follow all WARNINGS.
— Before starting to drive, check if the desired
selector lever position is displayed next to
the selector lever.
— The vehicle can roll even if the ignition is

switched off.

82
@) Note
Never let the vehicle roll downhill with engine
off and the selector lever in the "N" position,
because this could damage the automatic
transmission and catalytic converter.
(i) Tips
— Drive select: sporty shifting characteristics
can be selected using the Dynamic driving
mode. The Infotainment display shows “S”
as the selector lever position instead of “D”.
— If you accidentally select "N" while driving,
take your foot off the accelerator pedal im-
mediately and wait for the engine to slow
down to idle before selecting "D" or "S".
— If there is a power failure, the selector lever
will not move out of the "P" position. The >

press lock button on selector lever
The automatic shift lock only functions when the
vehicle is stationary or at speeds below 1 mph
(2 km/h). At higher speeds, the lock is automati-
cally deactivated in the "N" position.
The selector lever is not locked when shifting
quickly through "N", for example from "R" to "D".
This makes it possible to free the vehicle when it
is stuck by “rocking” it. The selector lever lock en-
gages if the lever stays in the "N" position longer
than approximately two seconds when the brake
pedal is not pressed.
Interlock button
The interlock button in the selector lever handle
prevents you from moving the selector lever in-
advertently while in some selector lever posi-
tions. The positions that require the interlock
button to be pressed are marked in color in the il-
lustration > fig. 88.

Z\ WARNING
Read and follow all WARNINGS. > A\ in Selec-
tor lever positions on page 82.
G) Tips
— If the selector lever does not engage, there
is a malfunction. The engine is disabled to
prevent the vehicle from driving off uninten-
tionally. To allow the selector lever to en-
gage again, proceed as follows:
— Briefly press the brake pedal.
— If the vehicle does not move forward or in
reverse even though a drive position is se-
lected, proceed as follows:
— If the vehicle does not move in the desired
direction, the system may not have engaged
the drive position correctly. Press the brake
pedal
and select the drive position again.
— If the vehicle still does not move in the de-
sired direction, there is a system malfunc-
tion. See an authorized Audi dealer or au-
thorized Audi Service Facility for assistance

Audi drive select (drive
settings)
Introduction
Applies to: vehicles with Audi drive select
Drive select makes it possible to experience dif-
ferent types of vehicle characteristics in one vehi-
cle. With different driving modes, the driver can
switch the setting, for example from sporty to
comfortable. In the Individual mode, the set-
tings can be adjusted to your personal preferen-
ces. This makes it possible to combine settings
such as a sporty drivetrain setting with comforta-
ble steering.


Using Audi drive select incorrectly can lead to
collisions, other accidents and serious inju-
ries.

Applies to: vehicles with Audi drive select

The vehicle setup in each mode depends on the
vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto-
matic transmission respond more quickly or ina
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in-
formation regarding steering movements, brak-
ing and acceleration operations by the driver, as
well as information about the road surface, driv-
ing speed, and load. With drive select, you can
adjust the suspension control to sporty (dynam-
ic), comfortable (comfort) or balanced (auto).
96

Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.


— Certain vehicle settings will be reset when
the ignition is switched off.
— In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
Selecting the driving mode
Applies to: vehicles with Audi drive select
You can choose between comfort, auto, dynamic
and individual.

— 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.

All wheel drive (quattro)
Applies to: vehicles with all wheel drive

The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
=> page 104.
The all-wheel drive system is designed for high
motor power. Your vehicle is exceptionally power-
ful and has excellent driving characteristics both
under normal driving conditions and on snow and
ice. Always read and follow safety precautions
>A.

Z\ WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.

108

— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the motor RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-

tions to reduce the risk of an accident.
