Seek medical attention immediately.
— Change your clothing immediately if it
comes into contact with tire sealant.
— If an allergic reaction occurs, seek medical
attention immediately.
— Keep the tire sealant away from children.
— In vehicles with a tire pressure monitoring
system*, using tire sealant can result in an
incorrect display or a system malfunction.
Drive carefully to the nearest authorized
Audi dealer or authorized Audi Service Facili-
ty.

@ For the sake of the environment
& Do not dispose of the compressor in house-
hold trash. It contains materials that can be
recycled. Contact an authorized Audi dealer or

tle. Replace the tire sealant at an author-
ized Audi dealer or authorized Audi Service
Facility.
— Radio reception can be interrupted when
operating the compressor.
— Follow the legal regulations that are appli-
cable in the country where you are operat-
ing the vehicle.

1) The compressor may look different. However, the way it is
operated is generally the same.

Emergency assistance

> Inflate the tire to between 29 psi (200 kPA) and
36 psi (250 kPA) and read the pressure on the
gauge.
> If this tire pressure is not reached, remove the
filler hose. Drive slowly approximately 33 feet
(10 m) forward or in reverse so that the sealant
can be distributed in the tire. Inflate the tire
again > A\.
ZX WARNING
— Read and follow the manufacturer's safety
precautions on the compressor and in the
instructions on the bottle of sealant.
— lf a tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not
continue driving.
— If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au-
thorized Audi Service Facility for assistance.
@ Tips
Do not operate the compressor for more than
six minutes continuously, or it can overheat.
Once the compressor has cooled, you can con-
tinue to use it.
Completing

80 km/h)" that is provided with the tire mobili-
ty kit within the driver's field of vision.
> Stop the vehicle after driving for about 10 mi-
nutes and check the tire pressure.
> If the tire pressure is lower than 19 psi (130
kPA), then the tire is too severely damaged. Do
not continue driving.

ZA\ WARNING

Spare tire

General information
Applies to: vehicles with space-saving spare tire (compact
spare tire)

Fig. 191 Luggage compartment: spare tire
The spare tire is intended for short-term use on-
ly. Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
248
Removing the spare tire
> Turn the handle > fig. 191 @ counter-clock-
wise.
> Remove the spare tire.
Removing the vehicle jack
> Lift up the cover on the right side of the lug-
gage compartment and remove the vehicle
jack.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the spare tire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.

ZA WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.

If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle >

8S1012721BE
Emergency assistance

battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.

ZA WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-
tery is frozen, it must be thawed before con-
necting the jump start cables. If it is not, the
risk of an explosion and chemical burns in-
creases. After jump starting the vehicle,
drive to an authorized Audi dealer or author-
ized Audi Service Facility immediately to
have the vehicle battery checked.
— Read the warnings when working in the en-
gine compartment > page 200.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.

@) Note
Jump start cables can cause considerable
damage to the vehicle electrical system if
they are connected incorrectly.
G) Tips
— There must be no contact between the
vehicles, or else voltage could flow when
connecting the positive terminal and drain
the vehicle battery of the vehicle providing
the jump start.
— The drained vehicle battery must be con-
nected correctly to the electrical system.
— Switch off electrical equipment that is not
needed.
arte la alate)

Both jump start cables must be connected in the
correct order.

If a new fuse burns out again shortly after you
have installed it, have the electrical system
checked as soon as possible by an authorized
Audi dealer or authorized Audi Service Facility.

Image recording
Surrounding area monitoring
Applies to: vehicles with surrounding area monitoring
Some vehicle functions require the vehicle’s path
to be detected and evaluated. This is done by
cameras installed permanently on the vehicle
that detect objects in the vehicle's surroundings
(such as obstacles or guard rails). The live images
from the cameras are transmitted to the applica-
ble control module.
The camera images are transmitted to the appli-
cable control module and stored for processing.
The control module analyzes the current camera
image using image evaluation software. This im-
age evaluation software detects anonymized
technical measurements, such as distances to ob-
jects. The control module evaluates these techni-
cal measurements and makes it possible for the
assist systems to control the vehicle, if necessary.

Fig. 200 Driver's side footwell: connection port for the On
Board Diagnostic System (OBD)
Your vehicle is equipped with electronic control
modules for various vehicle systems such as the
256

airbags. These vehicle control modules store data
while driving normally that is required by an au-
thorized Audi dealer or authorized Audi Service
Facility for diagnosis and repair purposes. Only
certain types of data are recorded for a very short
period of time if a control module has detected a
system event. No noises, conversations, or im-
ages will be recorded in the vehicle.
The data may include information such as the ve-
hicle speed, the direction of travel, and informa-
tion about the brake system, or also the behavior
of the restraint system in the event of an acci-
dent. The stored data can be exported and down-
loaded with special devices, which must be con-
nected directly to the vehicle.
On Board Diagnostic System (OBD)
There is a diagnostic connector socket in the driv-
er's side footwell to read out the various control
modules and the event data recorder. Data re-
garding the function and condition of the elec-
tronic control modules is stored in the event
memory. Only have an authorized Audi dealer or
authorized Audi Service Facility read out and de-
lete the event memory.

ZA\ WARNING
— Incorrect use of the connection port for the
On Board Diagnostic System can cause mal-
functions, which can then result in accidents
and serious injuries.
— Only allow an authorized Audi dealer or au-
thorized Audi Service Facility to read out the
motor data.
