2021 AUDI A6 battery

4K0012721BE
Emergency assistance

> Connect the compressor hose to a vehicle sock-
et and switch it on.
> Let the compressor run until the specified value
on the tire pressure sticker is reached
> page 266, fig. 169>@.
> Screw the valve cap back onto the valve.
Returning to storage
> To release air, turn the valve insert. See an au-
thorized Audi dealer or authorized Audi Service
Facility.
> Turn the valve insert back once the air has been
released.
> Wait several hours before placing the collapsi-
ble spare tire in the spare wheel well. Only then
will it fold down completely so that you can
store it securely.
> Then screw the valve cap back onto the valve.
> Secure the collapsible spare tire with the hand-
wheel.
> Fold the cargo floor cover back into place.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a front
tire fails, mount the collapsible spare tire in place
of a rear tire. Install the snow chains on the rear
tire that you removed, and install that in place of
the front tire that failed.

Z\ WARNING
— Only use the collapsible spare tire in emer-
gencies and drive very carefully, especially if
it is more than six years old.
— The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
— After installing a collapsible spare tire, the
tire pressure must be checked as quickly as
possible to reduce the risk of an accident.
— Do not drive faster than 50 mph (80 km/h)
with the collapsible spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the collapsible spare

tire.

— Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
— Normal tires or winter tires must not be
mounted on the collapsible spare tire rim.
C) Note
The compressor must be switched off after six
minutes at the most to reduce the risk of
overheating. Let the compressor cool down
for several minutes before using it again.


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.

Z\ 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, >

Emergency assistance


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 242.
— 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
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.
aT eile le)
Both jump start cables must be connected in the
correct order.

cables or a charger

Fig. 182 Connecting the jump start cables
The jump start cable connections are located in
the engine compartment.
Follow the information about the vehicle battery
=> page 252.
Connecting the positive cable (red) to the
positive terminal
> Open the red cover on the positive terminal
> fig. 181.
1. Attach one end of the positive cable (red) to
the jump-start pin @ © fig. 182 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. >

4K0012721BE
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.
@) 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.
C) 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


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.
G@) Tips
— The following table does not list fuse loca-
tions that are not used.


— Some of the equipment listed in the follow-
