Stopping and starting the engine
Applies to: vehicles with Start/Stop system
> Press and hold the brake pedal until the vehicle
has stopped. The @ indicator light appears in
the instrument cluster once the engine stops
automatically.
> The engine starts again when you remove your
foot from the brake pedal. The indicator light
turns off.
If the parking brake is set, the engine will only
start again when the accelerator pedal is pressed.
@) 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.
— If you leave the vehicle briefly during a Stop
phase and then enter again, the driver's
door must be closed and the safety belt
must be fastened in order for the engine to
be able to restart.
— 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.

Applies to: vehicles with Start/Stop system


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
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

This message appears when specific conditions
are not met during a Stop phase. The Start/Stop

Vehicle starting system: malfunction! Please
contact Service
There is a malfunction in the Start/Stop system.
Drive the vehicle to an authorized Audi dealer or
authorized Service Facility as soon as possible to
have the malfunction corrected.
Brakes
General information
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: >

Parking and maneuvering


the vehicle is too far. Make sure the connec-
tion is sufficient, and when in doubt, resume
parking the vehicle yourself.
— Blocking notifications, tones, and vibrations
increase the risk of an accident. The myAudi
app can only warn you if dangers are detect-
ed if you make sure that your mobile device
allows all notifications, tones, and vibra-
tions for the myAudi app.

@) Note
— Do not use remote controlled parking when
transporting cargo that projects outside of
the vehicle or when snow chains are mount-
ed.
— Remote controlled parking may guide the
vehicle either away from curbs or onto them
if other vehicles are parked on the curb.
Make sure that your vehicle's tires and rims
are not damaged. Resume control of the ve-
hicle in time or stop the parking process if
needed to prevent damage.
— In parking spaces without curbs, maintain a
distance of at least 19 inches (50 cm) from
walls and buildings in order to reduce the
risk of vehicle damage.
@) Tips
— Follow the legal regulations in the country
where you are operating the vehicle when
using remote controlled parking. Remote
controlled parking may be prohibited in
some countries. The system may be unavail-
able in countries where it has been deacti-
vated in order to comply with legal regula-
tions. Data will not be transmitted to Audi.
The driver is always responsible for adhering
to the regulations applicable in the country
where the vehicle is being operated.

— Do not endanger any other road users when
using remote controlled parking. Testing re-
mote controlled parking in a parking lot
with minimal traffic is recommended.
— Your mobile device should have a sufficient
battery charge level. If necessary, charge
the mobile device before starting to drive.
— Do not use the remote controlled parking
function with devices that are faulty or dam-
aged or whose function is impaired. Only
use the operating systems approved by the
mobile device manufacturer.
— When using remote controlled parking, al-
ways pay attention to the areas where your
vehicle can be accessed. Check that no one
can enter your vehicle and if the vehicle has
been locked after parking is completed.
Take the vehicle key with you when leaving
the vehicle.

tions remotely depends on the charge level
of the vehicle battery. Therefore, these
functions only have limited availability after
switching off the ignition.
— An eSIM card establishes the Internet con-
nection for Audi connect vehicle control
services. The costs for this are included in
the price of Audi connect vehicle control
services. The cell phone network, for exam-
ple, must be available to use these services.

body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.

in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.



A WARNING

fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.

Z\ WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
—The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized
Audi Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.
@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.
