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
CD 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 con­
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(·) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C). If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal 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.
- 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 gases.
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
qpage 155.
CD Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
