the tire that will be changed > fig. 183. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack.
>» Using the hex socket wrench (3) from the vehi-
cle tool kit, turn the vehicle jack under the lift-
ing point on the side sill until it is high enough
that the arm @) 9 fig. 184 is under the desig-
nated plastic mount.
> Align the vehicle jack so the arm @ engages in
the designated Lifting point in the door sill and
the base (2) lies flat on the ground. The base @)
must be directly under the mounting point ().
> To lift the vehicle, position the ratchet @ from
the vehicle tool kit with the correct side on the
hex socket wrench @).
> Move the ratchet (@) clockwise back and forth
until the wheel lifts up slightly from the
ground.

Z\ WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased when the ground is
slippery or soft, because the vehicle jack
could slide or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
— Applies to: vehicles with air suspension:
Changes in temperature or load can affect
the height of the stopped vehicle.


D Applies to: vehicles with ceramic brake rotors*: Use a sec-
ond alignment pin* from the vehicle tool kit for the lowest
hole according to the steps described for the first align-
ment pin.

—To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, no work should
be performed under the vehicle while it is
raised.
C) Note
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated mounting
points on the side sill. Otherwise, your vehicle
could be damaged.

ling unidirectional tires.
> Slide the wheel on over the alignment pin >@.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pin and tighten the re-
maining wheel bolt.
> Carefully lower the vehicle using the vehicle
jack*.
> Tighten the wheel bolts in a diagonal pattern
using the wheel wrench.
The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.

ZA\ WARNING
— Read and follow the important information
and notes under > page 253.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex socket will not achieve the required
tightening torque, which increases the risk

of an accident.
©) Note
When removing or installing the wheel, the
rim
could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
278
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> Store the replaced tire securely in the luggage
compartment > page 82.
» Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 265.
> The wheel bolt tightening specification must be
120 ft lbs (160 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
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
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.

Emergency assistance


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
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 233.
— 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.
@ 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.

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

Emergency assistance

> With the engines running, remove the cables in
reverse order of the way they were installed.
> Close the red cover on the positive terminal.

ZA WARNING
— Never connect the jump start cable directly
to your vehicle battery. Only use the connec-
tions in the engine compartment.
— Do not touch the non-insulated parts of the
terminal clamps. The cable must also not
come into contact with vehicle components
that conduct electricity when it is connected
to the positive vehicle battery terminal. This
can cause a short circuit.
— The plugs on the battery cells must not be
opened.
— Keep ignition sources (such as open flames,
burning cigarettes, etc.) away from the vehi-
cle batteries to reduce the risk of an explo-
sion.
— Route the jump start cables so they cannot
get caught in the moving parts in the other
vehicle's engine compartment.

@) Note
Please note that the connecting process previ-
ously described for the jump start cables is in-
tended for when your vehicle is being jump
started.
G) Tips
Make sure that the connected jump start ca-
bles have sufficient contact with metal.
Towing
General information
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
Towing requires a certain amount of practice.
Audi recommends contacting a towing company
to have the vehicle transported.
You should only have your vehicle towed by an-
other vehicle when disabled in exceptional cir-
280
cumstances. Inexperienced drivers should not
tow.
Notes on towing
When the engine is stopped, the transmission
will not be sufficiently lubricated if traveling at
high speeds and long distances:
— The maximum permitted towing speed is 30
mph (50 km/h).
—The maximum permitted towing distance is 30
miles (50 km).
Additional information on towing with a tow
truck
The vehicle may only be towed with the front axle
raised. Do not wrap any chains or cables around
the brake lines.
Tow bar and towing cable
The vehicle can be towed with a tow bar or tow-
ing cable. Both drivers should be familiar with
the special considerations when towing, especial-
ly when using a towing cable.
Always make sure the traction force does not ex-
ceed the permitted level and there are no shock
loading conditions. There is always the risk of the
coupling becoming overloaded when driving off-
road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
— To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.

() Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles

Fuses and bulbs

ZA WARNING
Do not repair fuses and never replace a blown
fuse with one that has a higher amp rating.
This can cause damage to the electrical sys-
tem and increases the risk of fire.

() Note
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 Facili-
ty.
@) Tips
— The following table does not list fuse loca-
tions that are not used.
— Some of the equipment listed in the follow-
ing tables applies only to certain model ver-
sions or certain optional equipment.

Data privacy

Data privacy
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 transferred to the respon-
sible control module for processing and may be
stored, depending on vehicle equipment. The
control
module analyzes the current camera im-
age using image evaluation software. This image
evaluation software detects anonymized techni-
cal measurements, such as distances to objects.
The control module evaluates these technical
measurements and makes it possible for the as-
sist systems to control the vehicle, if necessary.

Fig. 198 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
288

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.

Z\ 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.

(er) ata recorder
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;
