Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec-
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
@) Note
Vehicles with an automatic transmission can-
not be started by pushing or towing.
Jump starting
If needed, the engine can be jump started by an-
other vehicle battery.
Applies to: vehicles with plug-in hybrid drive: The
connection points for the jump start cable are
different > page 365.
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
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.

A WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-

364


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
increases. 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 304.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.
— Applies to: vehicles with plug-in hybrid
drive: You must not give a jump start with
your vehicle. This could cause significant
damage to the electrical system in your ve-
hicle > page 365.
— Applies to: vehicles with the battery in the
engine compartment: To reduce the risk of
chemical burns, do not bend over the vehicle
battery.

@) 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.

such as the engine block or transmission
are removed.
— When removing heavy components like
these, anchor vehicle to hoist or add corre-
sponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or
slip
off the hoist, causing serious personal
injury.

@ Note
— Be aware of the following points before Lift-
ing the vehicle:
— The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmission housing, the front
or rear axle or the body side members.

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. 292 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
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.

ZX 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
engine data.

Event Data Recorder

This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions,
such as an airbag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle's system performed. The EDR is
designed to record data related to vehicle dynam-
ics and safety systems for a short period of time,
typically 30 seconds or less. The EDR in this vehi-
cle is designed to record such data as:
— How various systems in your vehicle were oper-
ating;
— Whether or not the driver and passenger safety
belts were buckled/fastened;
— How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
— How fast the vehicle was traveling.

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from
vehicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
374
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.

Audi is not liable for damage to the vehicle re-
sulting from these country-specific differen-
ces.
Maintenance, repairs,
and technical modifi-
cations
Note the safety precautions > page 304, General
information and > page 354, Raising the vehicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.

Accessories and technical changes

Usually maintenance and repair work requires
special tools, measuring devices, and other
equipment that is available to trained vehicle
technicians in order to help ensure that your vehi-
cle and all of its systems operate correctly, relia-
bly, and safely. Performing work on the vehicle
incorrectly can impair the operation and reliabili-
ty of your vehicle and may void one or more of
your vehicle's warranties.
Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.
