@) 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.
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.
@) 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 152 when
loading the vehicle onto a vehicle carrier,
train, ship, or other type of transportation,
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 295. >

Emergency assistance

Preparations
> Only secure the towing cable or tow bar at the
designated towing loops > page 296,
=> page 297.
> 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 > /\.
> 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.


Z\ 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.
