_& WARNING
An improper f uel ing p rocedure and improper
hand ling of fue l can lead to exp losions, fires,
severe b urns and other injuries .
- Do not smoke and keep away from open
flames .
- T he ig nition m ust be switched off whe n re ­
f ueling .
- Cell pho nes, radio devices and o ther radio
equipment s hou ld always be switched off
w hen refueling . Electromagnetic rays cou ld
cause sparks and start a fire .
- If you do not insert the fuel pump nozzle a ll
the way into the filler tube, then fue l can
leak out. Spilled fue l can ignite and start a
fire.
- Never get into the vehicle when refueling. If
there is an exceptional s ituation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle aga in . This will reduce the
r isk of electrostat ic d ischarge that can cause
flying sparks . Sparks can start a fire when
ref uel ing .
_& WARNING
We recommend that you do not t ransport any
fue l co nta iners in t he veh icle. Fue l cou ld leak
out of the containe r and ignite, espe cially dur ­
ing an accident. This can cause exp losions,
fires and injuries .
- If you must transport fuel in a fue l contain ­
er, please note the following:
Ch eck ing and F illing
- Always place a fue l container on the
ground before filling . Never fill the fue l
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
wh ile refueling and the fuel vapors could
i gnite .
- For fuel containers made of metal, the fuel p ump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,
stor ing and t ransporti ng f uel conta iners.
- Make su re that the fuel containe r meets
t h e in dust ry standa rds, for example ANS I
o r ASTM F8S2 -86.
@ Note
- Remove fuel that has overflowed onto any
veh icle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel
tank is completely
empty. The irregula r supply of fue l that re­
sults from that can cause eng ine misfi res.
U nc ombus ted fuel will ente r th e exhaus t
system and increase the risk of damage to
the cata lytic converter.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise f uel
ca n leak o ut w hen the ve hicle is warming up.

Emissions control
system
Cat alytic converter
The vehicle may only be driven w ith unleaded
gaso line , otherwise the catalytic converte r will be
dest royed .
Never dr ive until the tank is completely empty.
The irregular supply of fuel that results from that can cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
&_ WARNING
The temperature of the exhaust system is
h igh, both when driving and a fter stopp ing
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park your vehicle over flammable
materials s uch as grass or leaves because
the high temperature of the emissions con­
trol system could start a fire .
- Do not apply unde rbody protectant in the
exhaust system area, beca use this increases
the risk of fire.

([) Note
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­ store the correct mixture ratio with the
spec ified coolant additive as soon as possi­
ble.
- Only refill with new coo lant.
- Radiator sealant must not be mixed w ith
the coo lant .
Adding coolant
F ig. 181 Engine compartment: coolant expans ion tank
cover
Observe the safety precautions~ page 189,
Working in the engine compartment .
Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank~ page 192, fig . 179. The coolant level
must be between the MIN and MAX markings
196
when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k
~CD -
• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 195 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his 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 ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if yo u
use the hex head, potentially causing an ac­
cident.
- The factory-supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which could cause an accident .
- Support the vehicle securely with appropri­ ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tential risk for injury .
- Never use the jack supplied with your Audi
on another vehicle, particularly on a heavier
one. The jack is only suitable for use on the
vehicle it came with.
