lect the P selector lever posit ion in vehicles
with an automatic transmission .
- Let the engine coo l down.
- Never open the hood when there is steam or coolant escaping from the eng ine compart­
ment, because there is a risk that you cou ld
be burned . Wait until no steam or coolant is
escaping.
- Keep children away from the engine com­
partment.
- Never spill flu ids on a hot engine. These flu­
ids (such as the anti-freezing agent con­
tained in the coolant) can ignite.
- Avoid sho rt circu its in the e lectrical system.
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ign ition is switched off , which
increases the risk of inj ury .
- Never open the cap on the coolant expan­
sion tank when the eng ine is warm. The
cooling system is under press ure.
- T o protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.

c ircumstances . This increases the risk of
burns .
Check ing and Filling
-If tests need to be performed with the en­
gine running, there is add itiona l danger due
to mov ing components (such as the ribbed
belt, alternator and radiator fan) and from
the high-voltage ignition system.
-Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the veh i­
cle is stat ionary but the eng ine is running
and a gea r is engaged. Otherwise, the veh i­
cle will start to move immed iate ly and this
could result in an accident.
- Pay attent ion to the following warn ings
when wor k on the fue l system is required :
- Do not smoke.
- Never work near open flames.
-Always have a working fi re extinguisher
nearby.
-All work on the battery or electrical system in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
o nly by an
author iz ed Audi dealer or author iz ed Audi
Serv ice Facility.
-To reduce the r isk of electric shock and in­
jury, never touch the following components
when the engine is runn ing or is being start­
ed:
- Ign ition cable
- Other components in the e lectronic high-
vo ltage ign ition system
-I f you must check or perform wo rk on the
engine wh ile it is running:
-First, set the parking brake and and move
the gearshift lever to neutral (for manual
transm issions) or select the P selector lev­
er position (for automatic transm iss ions).
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie bac k long hair befo re beginning
work and do not wear clothing that can hang down into the engine.
-Lim it your exposure to exhaust and chemi­
cals to as short a time as possible

Emergency situations
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
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con 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-
374
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
r=:> poge 323.
([) 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.

Consumer Info rmation
today's a utomo biles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Also , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustmen ts to en­
g ine and transmission parts wh ich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
eq uipped and qualified workshop . We strongly
urge you to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled mainte ­
nance and necessa ry repairs. Your dealer has the
facilities, origina l parts and tra ined specialists to
keep your veh icle runn ing prope rly.
Performing limited maintenance yourself
The fo llow ing pages describe a limited number of
procedures whic h can be performed on your vehi­
cle with ordinary tools, should the need arise and
tra ined personnel be unava ilable. Before per­
forming any of these procedures, always thor­
ough ly read all of the app licab le text and carefu l­
ly follow the instructions g iven . A lways rigorously
observe the
WARNINGS prov ided .
Befo re yo u check anything in the engine com ­
partment, always read and heed all WARNINGS
c::> & and c::> & in Working in the engine compart­
ment on page 323 .

A WARNING
-
-Ser ious personal in jury may occur as a result
of imp roperly performed maintenance, ad­
justments or repairs .
- Always be extreme ly careful when work ing
on the vehicle . Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never r is k personal in jury.
- Do not attempt any of the mainte nance,
