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 .
A 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 255
-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 195.
(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. ..,. •

-Jumper cables must be long enough so
that the vehicles do not t ouch.
- W hen connecting jumper ca bles, make
sure that they cannot get caught in any
moving parts in the eng ine compart­
ment.
- Do not bend over the batteries - danger
of chemical burns!
- The battery ce ll locking screws must be
t ightened securely .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
page 195.
Improper hook-up of jumper cables can ru­
in the generator.
- Always connect POSITIVE( +) to POSI ­
TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
ce lls are screwed in firmly . If not, tighten
plugs p rior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­
necting a jumper cable as described
above applies spec ifically to the case of
your vehicle be ing jump started. When
you are givi ng a jump start to another ve­
hicle, do
not connect the negat ive( -) ca­
ble to the negat ive( -) term inal on the
discharged battery @¢
fig. 202. In­
stead, securely connect the negative(- )
cable to e ither a solid metal component
that is firmly bolted to the engine block
or to the engine block itse lf. If the bat­
tery that is being charged does not vent
to the outside, escaping battery gas
could ignite and explode!

Emergency towing
with commercial tow
truck
General hints
Your Audi requires special handling for tow­
ing.
T he following information is to be used by
commercial tow t ruck operators who know
how to operate their equipment safely.
- Never tow your Audi , towing will cause
damage to the engine a nd transmi ssion.
- Never wrap th e safet y chain s or winch c a­
ble s around th e brak e lin es.
- To prevent unne ce ss ary dam age, your Aud i
mu st be t ransp orted with a flat bed truck .
- To load th e vehi cle on to the fl at bed , use
the t owing loop found in the vehicle t ool s
and atta ch to the front or rear anch o rage

260 Emergency situations
fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor­
responding weights to maintain the cen­
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servic ing in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authori zed Audi dealer or any properly
eq uipped and qua lified workshop. We st rong­
