Emergency assistance
> Check the tire pressure on the installed wheel
as soon as possible.
> Check the tire pressure and store it in the Info-
tainment system.
> The wheel bolt tightening specification must be
90 ft lbs (120 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.
ZA WARNING
— A drained vehicle battery can freeze at tem-
peratures around 32 °F (0 2C). If the vehicle
battery is frozen, it must be thawed before
connecting 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 229.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.
C) 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 vehi-
cles, or else voltage could flow when con-
necting 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.
Starting the engine
Both jump start cables must be connected in the
correct order.

Emergency assistance
The jump start cable connections are located in
the luggage compartment.
Follow the information about the vehicle battery
=> page 240.
Connecting the positive cable (red) to the
positive terminal
> Open the cover for jump starting > page 242,
fig. 188.
1. Attach one end of the positive cable (red) to
the jump start connection @ © fig. 207 on
your vehicle.
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 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 cover.
ZX WARNING
— 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.
278
—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.
— If you jump start another vehicle, route the
jump start cable so that it does not become
caught in moving components 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. If you are jump starting another vehi-
cle, connect the negative cable (-) to a large
metal component that is bolted securely to
the engine block, or to the engine block itself.
If the vehicle battery in the vehicle being
jump started is not vented to the outside,
there is a risk of explosion due to hydrogen
gas.
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. Au-
di 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:
