2014 AUDI A6 Jump starting the battery

(D Note
-Do not disconnect the ve hicle battery
when the ignition is on or when the en­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system .
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and w ill then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.

er and jump sta rt cables
Always read and heed all WARNINGS below

page 236 .
.,. Switch off the ignit ion and all electrical con­
s umer s.
.,. Make sure the area is well vent ilated when
you charge the battery .
.,. Open the engine hood

.,. Connect the charger connectors according to
the instructions to the
jump start bolts.
(Bolts under the red cover= "positive", Bolts
with hex head= "negative").
.,. Only now plug the mains lead for the charg­
ing equipment into the wall outlet and turn
it on

.,. When the battery is fully charged: Turn the
charging equipment off and
remove the
mains lead from the wall out let.

A discharged battery can
freeze at tempera­
tures of only
32 F0 (0 °C) . Allow a frozen bat­
tery to thaw completely before attempting to cha rge it
c::, ,&. . However, we recommend not
using a thawed batte ry again because the bat­
tery casing can be cracked due to ice fo rma­
tion and can leak battery ac id.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt )
When charging at low vo ltages (e.g. with a
trickle charger) , the battery cables do not
have to be disconnected first . The battery
caps should
not be opened when charging a
battery .
It is not necessary to
remove the battery from
the luggage compartment, and it is a lso not
necessary to disconnect the cab les .
Fast charging the battery (charging rate
above 14 .8 Volts)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
_& WARNING
-
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another veh icle,
using a
pair of jumpe r cables to start the en­
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with a low acid level in the battery.
- The vo ltage of the booster battery must
also have a 12-volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in­
jury.
- Never charge a frozen batte ry. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batter ies of different voltage or
substantially different capacity (Ah) rat­
ing may cause an exp losion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis ­
charged battery.
- Before you check anything in the engine
compartment, always read and heed a ll
WARNINGS¢
page 224.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, radio, etc .
- Th ere must be no electrical contact be­
tween the vehicles as otherwise current cou ld already start to f low as soon as the
positive(+) terminals are connected. .,.

@ Tips
The disc harged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charg ing the
battery, never connect the negative
ground cable to the battery negat ive post
because the ba ttery manager system must
be ab le to detect the battery's state of
charge. Always connect the negative
g round cab le to the negative ground pos t
of t he battery manager cont ro l unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described b elow!

Starting the engine • Sta rt the engine of the veh icle w ith the
booste r ba tte ry @ . Ru n the engine at a
moderate speed.
• Start engine w it h discharged vehicle battery
@ in the usual manner.
• If the eng ine fails to start, do not keep the
starter c ranking for longer than 10 seconds.
Wait for about 30 seco nds a nd the n try
aga in .
• With eng ine runni ng,
remove ju mpe r cab les
from both vehicles in the exact
reverse o r­
de r.
• Close the re d
cover on the positive te rm inal.
T he battery is v ented to th e outside to p rev ent
gases from en ter ing the veh icle in ter io r. Ma ke
s ur e th at the j umper clamps are well connec t­
ed with their meta l parts in full con ta ct w ith

To avoid se rious personal injury and dam­
age to the veh icle, heed all warnings and
instructions of the jumper cable man ufac ­
ture r. If in doubt, call for road service .
- Ju mpe r cables m ust be long enough so
that the veh icles d o not touch.
