Removing a wheel
> Remove the top wheel bolt completely using
the hex socket in the screwdriver handle from
the vehicle tool kit > fig. 789 and place it ona
clean surface.
> Then install the alignment pin from the vehicle
tool kit by hand in the empty wheel bolt hole
> fig. 190".
> Remove the rest of the wheel bolts.
» Remove the wheel >(). The alignment pin re-
mains in the hole while doing this.
Installing a wheel
Read the directions on > page 247 when instal-
ling unidirectional tires.
> Slide the wheel on over the alignment pin >@.

1) 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.
> 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 227.
— 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.
CG) 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.
U rectional 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
tires as soon as possible and restore the correct
running direction on all of the tires.

Emergency assistance

4. Attach the other end of the negative cable
(black) to the jump start connection @ on
the vehicle.
Starting the engine
> Start the engine in the vehicle giving the charge
and let it run at idle.
> Now start the engine in your vehicle, which has
the
drained battery.
> If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds.
> Turn on the rear window defogger in your vehi-
cle in order to reduce any voltage peaks that
may occur when disconnecting the jump start
cables. The headlights must be switched off.
> 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 locking bolts on the battery cells must
be tightened securely.
— Keep ignition sources (open flames, burning
cigarettes, etc.) away from the vehicle bat-
teries to reduce the risk of an explosion.
— Route the jump start cables so they cannot
get caught in the moving parts in the other

vehicle's engine compartment.

C) 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.
250
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-
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 (SO 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.
If the vehicle should be towed with the axle
raised, then the ignition must be switched off to
reduce the risk of damage to the drivetrain.
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 >

8S1012721BE
Emergency assistance

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
(50 km), then transport the vehicle ona
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
G) Tips
— If there is a power failure, the selector lever
will not move out of the "P" position. The
parking lock must be released using the
emergency release before towing the vehi-
cle > page 88.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information un-
der > page 250.
Preparations
> Only secure the towing cable or tow bar at the
designated towing loops > page 2517,
=> page 252.
> Make sure the towing cable is not twisted. Oth-
erwise it could disconnect from the towing loop
while towing.
> Switch the emergency flashers on in both
vehicles > page 38. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Be especially careful when accelerating.
» Avoid sudden braking or driving maneuvers.
Vehicle being towed (rear)
> Make sure the ignition is switched on so that
the steering wheel is not locked and so that you
can use the turn signals, the horn, and the
windshield wipers if needed > /A\.
> Switching it off before the vehicle has stopped
may impair the function of the brake booster
and power steering. You would then need to
use more force to steer and brake the vehicle.
> Release the parking brake > page 79.
> Select the “N” selector lever position.
> Make sure the towing cable is always taut.

ZA\ WARNING
— Never tow a vehicle using a tow bar or tow-
ing cable if the vehicle does not have electri-
cal power.
— If the vehicle runs out of power while it is
being towed, stop towing the vehicle imme-
diately and consult an authorized Audi deal-
er or qualified repair 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.

rash data recorder
Crash data recorder/event data recorder
Your vehicle is not equipped with a crash data re-
corder.
Vehicle information is stored temporarily in a
crash data recorder. This provides detailed in-
sight into the circumstances of an accident. In
vehicles with an airbag system, accident-related
information such as impact speed, seat belt sta-
tus, seat positions and deployment times may be >
