Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory. This coolant must not be not changed.
The coolant leve l is monitored through the. in­
d icator light~
page 26. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents. Only use the fo llow­
ing coolant add it ives. These additives may be
mixed w ith each other.

The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the eng ine.

- Befo re the start of winter, have an author­
i zed Audi dealer or authorized A udi Se rvice
Fac ility check if the coolant additive in your
328
vehicle matches the per cen tage appropriate
for the climate . This is especially important
when driving in colder climates.
- If the appro priate coo la nt additive is not
availab le in an eme rgency, do not add any
ot her additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant add itive as soo n as poss i­
ble.
- Only ref ill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant.

feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.

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-
372
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 322.
([) 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.

Emergency situations
-When connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
- Do not bend over the batteries -danger of
chemical burns!
- The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
i=> page 322.
(D Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE(+) to POSITIVE
(+), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager control
unit.
- Check that all screw p lugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connect ing clamp on negative
battery terminal.
- Please note that the procedure for connect ­
i ng a jumper cable as described above ap­
plies specifically to the case of your vehicle
being jump started . When you are giving a
ju mp start to another vehicle, do
not con­
nect the negative (-) cable to the negative
(-) terminal on the discharged batte ry @
c> fig. 293. Instead, securely connect the
negative( -) cab le to either a solid metal
component that is firm ly bolted to the en­
gine block or to the engine block itself. If
the battery that is being charged does not
vent to the outside, escap ing battery gas
could ignite and explode!
Towing with a tow truck
General hints
Your Audi requires special handling for towing.
The following information is to be used by com­
mercial tow truck operators who know how to op­
erate the ir equipment safely.
-Never tow your Audi, towing will cause dam­
age to the engine and transmission.
374
-Never wrap the safety chains or winch cables
around the brake lines .
- To prevent unnecessary damage, your Audi
must be transported with a flat bed truck .
- To load the vehicle on to the flat bed, use the
towing loop found in the vehicle tools and at­
tach to the front or rear anchorage
