Driving


— If the engine must run while you are working
in the engine compartment with the hood
open, make sure a gear is not engaged. The
selector lever must be firmly in the P posi-
tion and locked in place and the parking
brake must be set > page 200. Otherwise,
the vehicle could begin moving when in-
creasing the engine speed, even with the

parking brake set.

() Note
— If you have to stop on an incline, always
press the brake pedal to hold the vehicle in
place to reduce the risk of the vehicle rolling
backward. Do not try to hold the vehicle in
place by pressing and holding the accelera-
tor pedal. The transmission can overheat,
which increases the risk of damage.
— Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans-
mission because it is not lubricated under
those circumstances.
— The transmission can overheat and be dam-
aged under certain driving and traffic condi-
tions such as frequent starts, creeping fora
long time, or stop-and-go traffic. When the
i or os] indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 87.
— Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans-
mission because it is not lubricated
= page 250, Towing.
@® Tips
For safety reasons, the parking brake is re-
leased automatically only when the driver's
safety belt is fastened.
Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec-
tor lever is in the "D" or "S" position and you
press the brake pedal. The transmission auto-

matically selects a gear that is suitable for the
hill. Hill descent control tries to maintain the
speed that was selected at the time of braking,
within physical and technical limitations. If may
still be necessary to adjust the speed with the
brakes. Because hill descent control cannot shift
down farther than 3rd gear, it may be necessary
to shift into tiptronic mode in very steep areas. In
this case, shift manually into 1st or 2nd gear in
tiptronic mode to use the engine's braking force
to relieve the brakes.
Hill descent control switches off once the hill lev-
els
out or if you press the accelerator pedal.
On vehicles with a cruise control system*
= page 89, hill descent control is also activated
when the speed is set.

ZA\ WARNING
Hill descent control may not be able to main-
tain a constant speed under all conditions. Al-
ways be ready to apply the brakes.
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually.

off briefly. To switch from manually shifting back
to automatic shifting immediately, tap the shift
paddle @) © fig. 97 for 1 second.
To keep shifting manually, tilt the selector lever
toward the front passenger's side.
@ Tips
— The transmission only allows manual shift-
ing when the engine speed is within the per-
mitted range.
— The transmission automatically shifts up or
down before critical engine speed is
reached.
— Applies to: RS models: When accelerating,
the transmission will not automatically shift
to the next gear shortly before the maxi-
mum permitted engine RPM is reached.
Shift to the next highest gear at the right
time.
86
Kick-down enables maximum acceleration.
When you press the accelerator pedal down be-
yond the resistance point, the automatic trans-
mission downshifts into a lower gear and the en-
gine utilizes its full power, if the vehicle speed
and engine RPM permit. It shifts up into the next
higher gear once the maximum permitted engine
RPM is reached.

ZA\ WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac-
tive.
Launch Control
Applies to: vehicles with Launch Control

Launch Control provides the best possible accel-
eration when starting from a stop.
Requirements
— The engine must be at operating temperature.
— The steering wheel must not be turned.
— Start/Stop system* must be deactivated

Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set in the Infotainment sys-
tem for this purpose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
@) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are adhering
to the legal speed limit.
Setting the warning threshold
Applies to: vehicles with speed warning system

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Driver as-
sistance > Speed warning > Manual.
Messages
Applies to: vehicles with speed warning system
ol Manually set speed limit XX mph
(km/h) exceeded

The stored speed was exceeded.
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions
are poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
@) Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and reduces the load placed on
the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

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

Intelligent Technology

— If malfunctions occur in other systems or
certain driver assist systems are active, the
ESC must be switched on by the system. The
ESC
may switch on automatically and can-
not be operated with the button.
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.
