Emergency Situations; General; Starting By Pushing Or Towing; Starting With Jumper Cables - Audi A4 2012 Owner's Manual

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 operations.
Starting by pushing or
towing
(D
Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
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 vehicle,
using a
pair of jumper cables
to start the en-
gine.
Jumper cables
Use only jumper cables of sufficiently
largecross section
to carry the starter current
safely. Refer to the manufacturer's specifica-
tions.
Use only jumper cables with insulated termi-
nal clamps which are distinctly marked:
plus(+) cable
in most cases colored
red
minus(-) cable
in most cases colored
black .

WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean-
ing over the battery whenever possible.
Emergency situations 2 79
- A discharged battery can freeze at tem-
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, 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 voltage 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 different voltage
or substantially different "Ah" rating
may cause an explosion and personal in-
jury.
- Never charge a frozen battery. 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 batteries of different voltage or
substantially different capacity (Ah) rat-
ing may cause an explosion and injury.
The ca pa city (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 all
WARNINGS c::;,page 225, Engine com-
partment.
(D
Note
- Applying a higher voltage booster bat-
tery will cause expensive damage to sen-
sitive electronic components, such as
control units, relays, radio, etc .
- There must be no electrical contact be-
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,.
