Connecting the positive cable (red) to the
positive terminal
> Open the cover on the positive terminal
> fig. 179.
1. Attach one end of the positive cable (red) to
the jump-start pin @ © fig. 180 on your vehi-
cle.
2. Attach the other end of the positive cable
(red) to the positive terminal @ on the pow-
er source.
Connecting the negative cable (black) to the
negative terminal
3. Attach one end of the negative cable (black)
to the negative terminal @) on the power
source.
4. Attach the other end of the negative cable
(black) to the jump-start pin @) on the vehi-
cle.
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 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-
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.

Emergency assistance

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
(50 km), then transport the vehicle on a
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 the power supply is interrupted, then it
will not be possible to move the selector
lever out of the "P" position. The parking
lock must be released using the emergency
release before towing the vehicle
=> page 100.
— Switch Audi pre sense* off > page 146 when
loading the vehicle onto a vehicle carrier,
train, ship,
or other type of transportation,
270
or when towing the vehicle. This can prevent
an undesired intervention from the pre
sense* system.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information under
=> page 269.
Preparations
> Only secure the towing cable or tow bar at the
designated towing loop > page 271.
> 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 53. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Press the brake pedal very carefully.
> 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 106.
> 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.

Data privacy

— 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.
These data can help provide a better understand-
ing of the circumstances in which crashes and in-
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e.g.
name, gender, age, and crash location) are re-
corded. However, other parties, such as law en-
forcement, could combine the EDR data with the
type of personally identifying data routinely ac-
quired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer, other parties, such as law enforcement,
that have the special equipment, can read the in-
formation if they have access to the vehicle or the
EDR.
Data usage
Audi can read out the information stored in the
data memories or similar data, or give this infor-
mation to third parties, especially in the follow-
ing situations:
— If the vehicle owner or lessee agrees
— If there is an official request from the police
— Ifa court or authorities request it
If legally permitted, Audi can also use the data
for analysis of vehicle operation and safety per-
formance or provide this data to third parties for
research purposes.
