Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Jump starting
Preparation
If needed, the engine can be jump started by an­
other vehicle battery.
Applies to: vehicles with plug-in hybrid drive: the
connection points for the jump start cable are
different
q page 102.
If the engine does not start because the vehicle
battery is drained, you can jump start the engine
using another vehicle battery. You need a jump
start cable 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.
Emergency situations
A WARNING
--
- Applies to: vehicles with plug-in hybrid
drive: you must
not give a jump start with
your vehicle . This could cause significant
damage to the electrical system in your ve­
hicle
Q page 102.
-A drained vehicle battery can freeze at tem­
peratures around 0
Q(. If the vehicle battery
is frozen, you must thaw it before connect­
ing the jump start cables. If you do not, this
increases the risk of an explosion and chem­
ical burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- The engine compartment is a dangerous
area and can cause serious injuries. Before
working in the engine compartment, read
and follow the warnings
Qpage 318.
- Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries . To reduce the
risk of injury, observe the following:
- 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 terminal. This can cause a
short circuit.
- Route the jump start cables so they cannot
get caught in the moving parts in the engine
compartment.
- To reduce the risk of chemical burns, do not
bend over the vehicle battery.
- 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.
- Do not clamp the negative cable to fuel sys­ tem components or to the brake lines.
(LlJ} Note
- There must be no contact between the
vehicles, If there is, current could already be
.,.

Emergency situations
flowing when connecting the positive termi­
nals and the vehicle battery in the vehicle
providing the jump start cou ld be drained.
- Jump start cables can cause considerab le
damage to the vehicle electrical system if
they are connected incorrectly.
- The drained vehicle battery must be con­
nected correctly to the electrical system.
- P lease note that the connecting process de­
scribed below for the jump start cables is in­
tended for when your vehicle is being jump
started. If you are jump starting another ve­
hicle, do not connect the negative cable to
the negat ive terminal( -) on the drained ve­
hicle battery, but rather connect it to a large
metal component that is bolted securely to
the engine block, or to the engine block it­
se lf. If the vehicle battery in the vehicle be­
ing jump started is not vented to the out ­
side, there is a risk of explosion due to hy­
drogen gas.
@ Tips
If a car phone is installed, switch it off or
check the operating guide for what to do in
this situation.
