A WARNING
- Never turn off the eng ine before the ve
hicle has come to a complete stop . The
full function of the brake booster and the powe r steering is not guaranteed. You
must use more fo rce to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to acc idents and se rious injuries.
- Never remove the ign ition key from the
ign ition lock whi le the vehicle is movi ng .
Otherwise, the steering lock co uld sud
denly engage and you would not be able
to steer the vehicle.
- Please note that the brake booster and
power steering only work when the en
gine is runn ing. When the engine off, you
must use more force to steer or brake
the vehicle. Because t he usual steering
and braking capability is not available,
the risk of accidents or injuries increases .
- Always take the vehicle key with you
when leaving the veh icle, even for a
short per iod of time. This applies partic
ularly when chi ldren remain in the vehi
cle. Otherwise the children could start
the engine or operate electrical equip
ment such as power windows .
- For safety reasons, always park the vehi
cle with the selector lever in the P posi- tion. Otherwise, there is the risk t
hat the
veh icle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
sw itched off. It can also sw itch on again
after some t ime if the coolant tempera
ture rises as a resu lt of heat buildup or if
the engine compartment is heated by
sunlight and the engine is hot.
(D Note
- If the engine has been under heavy load
for an extended per iod of t i me, heat
builds up in the engine compartment af
ter the engine is switched off - there is a
r isk of damaging the engine . For this
reason, let the engine r un for at id le for
approximately two minutes before shut
ting it off .

A WARNING
To reduce the risk of injur ies, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position .
- Let the engine coo l down.
- Never open the hood when you see that
steam o r coolant drips from the engine
c ompartment- there is a danger of
burns! Wait until no steam or coolant
flows out.
- Keep chi ldren away from the engine com
partment.
- Never spill flu ids on a hot eng ine. These
fluids (such as the freeze protection con
tained in the coolant) can catch fire .
- Avo id short circuits in the electrical sys
tem, especially the battery . -
When working in the engine compart
ment, remember that the radiator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
personal injury.
- Never open the cap on the coolant ex
pans ion tank when the eng ine is warm.
The cooling system is unde r pressure.
- To protect your face, hands, and arms
from hot steam or coolant, cover the cap
with a large cloth when opening .
- Do not remove the engine cover under any circumstances. This increases the
risk of burns .
- If tests need to be performed with the engine runn ing, there is add itiona l dan
ge r due to moving components (such as
the ribbed belt, generator and radiator
fan) and from the high voltage ignit ion
system.
- Never reach into the radiator fan. The
electric auxilia ry fan is controlled by
temperature and can switch on sudden ly .
- Pay attention to the fo llow ing warnings
listed when work on the fuel system or
on the e lectrica l equipment is required.
- Always disconnect the vehicle battery
from the vehicle e lectr ical system
- Do not smoke
- Never work near open flames
- Always have a working fire exting uisher
nearby
- To reduce the risk of electric s hock and
inj ury, never touch the fo llowing compo
nents when the engine is running or is
be ing started :
- Ig nition cable
- Other compone nts in the electronic
high voltage ign it ion system
- If you must check or perform work on the eng ine while it is runn ing:
- Set the parking brake and place these
lector lever in the P (park) position
first.
- Always proceed with extreme caution
so that clot hing, jewe lry or long hai r do
not become caught in the radiator fan, ..,.

"' Switch the ign ition off.
"' Read the coo lant level on the coolant expan
s ion tank
c::> fig. 168. The coolant level must
be between the markings whe n the eng ine
in cold. When the eng ine is warm it can be
slight ly above the upper marking .
Adding coolant
Requirement: There must be a residua l
amo unt of coolant in the expansion tank

"'Let the engine coo l down .
"' Place a cloth over the coolant expa nsion
tank cap and unscrew the cap counter clock

"'Add coolant mixed in the correct ratio
c::>page 220 up to the upper marking.
"' Make sure that the fluid level remains sta-
ble. Add more coolant if necessary.
"' Clove the cap securely.
A coolant loss suggests a leak. Immediately drive your vehicle to an authorized repair fa
cility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over
heat ing and being pushed out of the cooling
system.
Che cking and Fillin g 221
A WARNING
The cooling system is pressurized and can
become very hot. To reduce the r isk of
burns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine hot . The re is a risk of
burns .
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tank cap with a large, th ick
cloth .
- Tu rn the coolant tank cap counterclock
wise slowly and keep light pressure on
the cap.
- To reduce the risk of burns, do not allow
any antifreeze o r coolant to drip onto the
exhaust system or hot engin e compo
nents . The ethy lene g lycol in eng ine
coo lant can catch fire under certai n cir
cumstances.
- The coolan t addi tive and the coolant can
be dangerous to your health. For this
reason, keep the coo lant in the origina l
container away from ch ildren. There is a
risk of poisoning.
- When working in the engine compart
ment, remember that the radiator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
personal injury.
(D Note
Do not add coolant if the expans ion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue dr iving. See an author ized
Audi dealer or authorized Audi Service Fa
c ility for ass istance.
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
