General information
Within system limits, the exit warning system
can detect traffic approaching from behind such
as vehicles, and provide assistance based on this
information when you are exiting the vehicle
=> fig. 133. The system uses the data from the ra-
dar sensors at the rear corners of the vehicle.
Displays and warnings
If you pull a door handle while the vehicle is sta-
tionary and an object classified as critical is ap-
proaching, the warning strip @ and the display
on the exterior mirror (2) will light up on the cor-
responding side of the vehicle. The opening of
the door will also be slowed briefly.
If the door is opened, the displays on that side
will flash. If another road user that is classified
as critical is approaching while a door is already
open, the displays on that door will turn on.

Fig. 141 Upper display: aiming at a parking space
When parking with the rearview camera or pe-
ripheral camera, the parking system plus audio
and visual warnings* will also assist you
=> page 189.
Visual orientation lines
@ The orange orientation lines show the vehi-
cle's direction of travel >@. Turn the steer-
ing wheel until the orange orientation lines
align with the parking space.
@) Use the blue markings to help you estimate
the distance to an obstacle. Each marking
represents approximately 3 feet (1 meter).
The blue area represents an extension of the
vehicle's outline by approximately 16 feet (5
meters) to the rear.
@® You can recognize the rear bumper in the
lower display.
@ You should stop driving in reverse when the
red orientation line touches the edge of an
object, at the latest.

— The orange orientation lines @ show the di-
rection the rear of the vehicle will be travel-
ing, based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle. Maintain plenty of
distance so that an exterior mirror or a cor-
ner of the vehicle does not collide with any
obstacles.
— Keep enough distance from the curb to
avoid damage to the rims.
— Only use the images provided by the camera
on the rear of the vehicle when the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera.
G) Tips
Applies to vehicles with air suspension: The
accuracy of the orientation lines and blue sur-
faces on the camera display decreases when
the vehicle is raised or lowered with the air
suspension.

partment lid are closed.
Starting the parking process
> Start the myAudi app soon, or the function will
be canceled.
> Pay attention to the path of the vehicle. If the
traffic situation permits, park your vehicle in
the parking space using the mobile device
> JX. The vehicle key and the mobile device
cannot be more than approximately 20 feet
(6 m) away from the vehicle.
> Pay attention to the path of the vehicle. In un-
clear situations, pause the parking process us-
ing
the mobile device. For example, this may be
necessary if an obstacle appears or the vehicle
comes very close to an obstacle.
> To resume the parking process, start it again on
the mobile device. The rest of the parking proc-
ess will be recalculated based on the vehicle po-
sition.
End of the parking process
If an obstacle appears, stop the parking process
=> page 206.
The parking process will end automatically once
the vehicle has reached the end point in the park-
ing space. Once parking is successfully complet-
ed, the parking lock will be engaged, the parking
brake will be set, and the engine will switch off.
The vehicle will also be locked.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
— Failing to pay careful attention to the vehi-
cle's surroundings increases the risk of an
accident. Park your vehicle with the mobile
device only if you are sure that no obstacle is
in the vehicle's path or under the vehicle,
and that no obstacles will move into the ve-
hicle's path.
@ Tips
— If the parking space is located in a garage, it
must be detected correctly by the vehicle.
When the parking space is detected com-
pletely, the edges of the space will be high-
lighted @).
— The parking process can only be started if
the vehicle key is located outside the vehicle
after the vehicle is prepared. Always keep
both the vehicle key and the mobile device
with you during the entire remote control-
led parking process.
— Remote controlled parking may be restrict-
ed or unavailable in situations such as the
following:
—If the ESC is restricted or switched off, or
if there is a malfunction.
—If there is another vehicle key inside the
vehicle or nearby.
— The system can incorrectly interpret parking
space barriers (such as parking curbs). Take
over the parking process > page 206 if the
vehicle is not completely inside the parking
space or if the vehicle tries to drive over the
parking space barrier.

Checking and Filling

corrosion damage and damage to plastic or
rubber components in the fuel system.
— Do not use gasoline that does not meet the
specifications.
— If you are unable to find out if a specific gas-
oline mixture meets the specifications, ask
the gas station operator or their fuel suppli-
er.
— Do not use any gasoline mixture whose
composition cannot be identified.
— Audi does not assume any responsibility for
damage to the fuel system or for perform-
ance problems caused by using gasoline
mixtures different from those specified.
This type of damage also does not fall under
the New Vehicle Limited Warranty or under
the emissions control system warranty.
— If you notice a higher fuel consumption or
poor handling or performance problems due
to such gasoline mixtures, Audi recom-
mends fueling with unblended gasoline.
Gasoline additives
An important issue for many automobile manu-
facturers is combustion residue in the engine
that results from the use of certain fuels.
Although types of gasoline differ depending on
the manufacturer, there are similarities. Certain
substances in the gasoline may cause deposits in
the engine. Additives in the gasoline that should
keep the engine and fuel system clean do not all
function equally.
Audi recommends using TOP TIER Detergent Gas-
oline. For additional information on TOP TIER De-
tergent Gasoline, visit www.toptiergas.com.
If you use incorrect fuels over a long period of
time, the maximum engine performance may be
impaired by combustion residue.
@) Note
— Damage or malfunctions caused by the use
of incorrect types of gasoline are not cov-
ered by the New Vehicle Limited Warranty.
— Only gasoline additives that have been ap-
proved by Audi may be used.

Z\ WARNING
Improper fueling procedures and improper
handling of fuel can lead to explosions, fires,
severe burns, and other injuries.
— Do not smoke. Keep away from open flames.
— The ignition must be switched off when re-
fueling.
— Mobile devices, radio devices, and other ra-
dio equipment should always be switched
off when refueling. Electromagnetic rays
could cause sparks and start a fire.
— If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
— Never get into the vehicle when refueling. If
there is an exceptional situation where you
must enter the vehicle, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.

Z\ WARNING
Audi does not recommend transporting fuel

containers inside the vehicle. Fuel could leak

out of the container and ignite, especially dur-
ing an accident. This can cause explosions,
fires, and injuries.
— If you must transport fuel in a fuel contain-
er, note the following:
— Always place the fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is inside or on
the vehicle. Electrostatic discharge can oc-
cur while refueling and the fuel vapors
could ignite.
— When using fuel containers made of met-
al, the fuel pump nozzle must always re-
main in contact with the container to re-
duce the risk of static charge.
— Insert the fuel pump nozzle as far as pos-
sible into the filler opening while refuel-
ing.
— Follow the applicable legal regulations in
the country where you are driving when
using, storing and transporting fuel con-
tainers.
— Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.

©) Note
— Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
— Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re-
sults from that can cause engine misfires.
Uncombusted fuel may enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@) For the sake of the environment
— Do not overfill the fuel tank, or fuel could
leak out when the vehicle is warming up.
— Fuel should never enter the sewer system or
come into contact with the ground.
@) Tips
The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside us-
ing
the central locking switch.
272
G) Tips
Applies to: vehicles with plug-in hybrid drive
— When inserting the fuel pump nozzle, make
sure that you do not press on the fuel filler
door opener @) with the fuel pump nozzle.
See the label in the fuel filler door @)
> fig. 176. Otherwise, a valve will close in
the fuel filler neck and fueling will stop even
if the tank is not full.
— You must vent the tank system again if you
press on the fuel filler door opener. The fuel
pump nozzle can stay in the fuel filler neck
when doing this. Vent the tank system by
pulling the EQ) switch in the driver's door
again.
— If the engine turned off because the fuel
level was too low, then you may need to re-
fuel with up to 4.0 gallons (15 liters) of fuel
in order for the vehicle to detect the new
fuel level. Otherwise, the engine may not
restart.
— Fuel can age and may lead to problems
when starting. Audi recommends replacing
the fuel in your vehicle within six months.
