2021 AUDI Q8 tires

Parking and maneuvering

@) Tips
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterward by pressing Pe.
— The Electronic Stabilization Control (ESC)
must not be switched off during the parking
process. If the ESC intervenes, the parking
process will be canceled.
— You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space (4)
=> page 168, fig. 126 so that the sensors
can measure the space.
— You cannot park with the parking assist sys-
tems when you are towing a trailer or have
the connector inserted in the trailer socket.
— The system is not available when certain as-
sist systems are switched on.
— If there are suitable parking spaces on both
sides of the street, for example, on a one-
way street, you can change the side where
the system is searching for parking spaces
by activating the turn signal for the other
side or by pressing on that side in the upper
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist plus!)2)
General information
Applies to: vehicles with park assist plus
Park assist plus parks the vehicle after the park-
ing space search and also exits the parking space.
While the driver presses and holds the [>>P] but-
ton and monitors the vehicle's surroundings, park
assist plus controls the steering, gear selection,
acceleration, and braking.



)_ system availability may be limited depending on the mar-
ket.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Note
— Do not use park assist plus when transport-
ing cargo that extends outside of the vehicle
or when snow chains are mounted.
— Park assist plus and remote controlled park-
ing guides the vehicle either away from
curbs or onto them if other vehicles are
parked on the curb. Make sure that your ve-
hicle's tires and rims are not damaged. Re-
sume control of the vehicle 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.
G) Tips
Follow the legal regulations in the country
where you are operating the vehicle when us-
ing park assist plus. Park assist plus may be
prohibited in some countries. The system may
be unavailable in countries where it has been
deactivated in order to comply with legal reg-
ulations. Data will not be transmitted to Audi. >

Parking and maneuvering


— Remote controlled parking is only an assist
system. The driver is always responsible for
maneuvering, driving, and stopping the ve-
hicle and performing other driving maneu-
vers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— Failing to pay careful attention to the vehi-
cle's surroundings increases the risk of an
accident. Sensors and cameras have spots in
which the surrounding area cannot be de-
tected. Objects, animals, and people may
only be detected with limitations may not
be detected at all. Always monitor the traf-
fic as well as the vehicle's surroundings with
direct eye contact. Stay near the vehicle
while controlling it. Make sure you have a
clear view of the vehicle and the area sur-
rounding it. Do not become distracted.
— Applies to: vehicles with anti-theft alarm
system: There is a risk of fatal injury for peo-
ple locked in the vehicle, especially children.
The vehicle is locked during remote control-
led parking. Make sure there are no persons
inside the vehicle both before and after us-
ing remote controlled parking.
— There is a risk of asphyxiation. Never allow
the engine to run in confined spaces. After
remote controlled parking, make sure the
engine is off.
— Malfunctions when using the myAudi app in-
crease the risk of an accident. Do not exit
the app during the parking process, and
make sure that it does not go into the device
background, for example by accepting an in-
coming call. Observe the operating instruc-
tions from the manufacturer of your mobile
device.
— There is a risk of accident if the connection is
interrupted. In certain situations, the con-
nection between the mobile device and the
vehicle can be interrupted, for example from
other radio devices or when the distance to
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.
G) 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.
— Any individual that uses the mobile device
for remote controlled parking is considered
the driver and is participating in traffic. The
driver is always responsible for adhering to
the regulations for using remote controlled
parking that are 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. >

and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
> Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil,
grease, and fuel.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them ina cool, dry location
with as little exposure to light as
possible.

J WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.

256


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends winter tires during the
winter months. Low tempera-
tures significantly decrease
the elasticity of summer tires,
which affects traction and
braking ability. If summer
tires are used in very cold tem-
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.
