-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always
dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle
used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Coo Ling system
Coolant
The engine coolant performs two functions: it
keeps
the engine from overheating and it pro
tects the engine from freezing in the winter.
The cooling system is sealed and generally re
q uires
little attention.
The cooling
system has been filled at the factory
with a
permanent coolant which does not need to
be changed. The coolant consists of a mixture of
specially conditioned water and the manufactur
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod
els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool
ing
system from corrosion and scaling. It also
raises
the boiling point of the coolant.
Do not reduce the concentrat ion of the coolant in
the summer by addi ng p la in water. The propor
tion of coolant additive must be at least 50°/o
but not more than 60°/o to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en
gine cooling system.
For year-round driving,
antifreeze is added at the
factory for temperatures down to:
- -
31 °F ( -35 °C) USA
- -40 °F ( -40 °C) Canada.
242
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled
water is recommended.
A WARNING
~ h . Before you check anything in t e engine com-
partment, always read and heed all WARN
INGS C)page 236.
CD Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in you r
vehicle is
sufficient to meet the climate con
d itions. This is especia l
ly important if you
live
in a regio n where the winter is extre m e
ly cold . If necessary, increase the proportion
o f coo la
nt ad ditive to 60o/o.
-When add ing coolant additive to your cool
ing
system, remember:
-We recommend using only coolant addi
tive G12++
or G13 (check the label) for
your vehicle. This coolant additive is avail
able at authorized Audi dealers. Other
types of antifreeze can significantly re
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage.
-Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra
dia to r repair fluid may adversely
affect the
func tion and performance of your cooling
system and could result in damage not cov
ered by your New Veh icle Limited W arranty .

Battery
General information
The battery in your Audi does not need any main
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem
peratures or when driving all day. The electrolyte
level should also be checked each time the bat
tery is charged ~page 247.
Have the battery checked when you bring your ve
hicle
in for an inspection . It is a good idea to re
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other
wise explosive
gas will escape from the bat
tery and increase the risk of an exp losion. ___ ....J
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart
ment under the floor . Before you check anything
in the luggage compartment, read and heed all
WARNINGS~_&.
Always heed the safety warnings , when working
on
the vehicle battery or the vehicle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:

Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle Q page 92. The intelli
gent energy management system will keep the
engine battery charged better than vehicles with
out this system. To make sure the additional
electrical energy is available once again after you
have
changed the battery, we recommend that
you install batteries of the same type and manu
facture only (the same as those insta lled at the
time your vehicle was delivered). Specificat ions
are listed on the battery housing. Your author
ized dealer must code the battery in the energy
management system to enable you to use the en
ergy management functions correctly after re
placing the battery.
The new
battery must have the same capacity,
voltage (12-volts) , amperage, construction and
plug sealing.
When installing the battery, make sure the igni
tion and all electrical consumers are switched
off.
CD Note
Make
sure the ventilation hose on the side of
the battery is connected, otherwise fumes or
battery acid can leak out.
@ For the sake of the environment
Because
of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all
environmental regulations. Disposing
of vehicle batteries improperly is very danger
ous to the environment.

In order to minim ize the occu rrence of impact
damage to the ti res of your vehicle, we recom·
mend that you observe the fo llowi ng p recau ·
tions:
- Always
maintain recommended inflation p res·
sures. Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary.
- Drive carefully on
roads with potholes, deep
gullies or ridges. The impac t from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
- Af t
er any impact, immediately inspec t your
tires o r have them inspected by the nearest au
thorize d Audi dealer. Replace a da maged t ir e as
soo n a s possib le.
- In sp e

e a sy to
see. Damage can lead to loss of air and
un
deri n flation, which could eventually cause
tire failure. If you believe that a tire may have
been damaged, replace the tire as soon as pos
sible.
- These
tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handling, they may ride less
comfortably and make more no ise than other
choices.

Reduced performance in winter/co ld season
conditions
All ti res are designed fo r certain purposes. The
low
aspect ra tio, ultra high performance tires
originally installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
circumstances, you should equip your vehicle
with all-season
or winter tires, which offer better
tract ion under those conditions. We suggest you
use the re commended snow or all-season tires
spe cified for your vehicle, or their equiva lent.

The relative performance of tires depends upon
the a ctual conditions of their use, however, and
may depart significant ly from the norm due to
varia tions in driving habits, service practices and
differences in road characteristics and cl imate.

The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on

The temperature grade for this tire is estab-
lished for a t
ire that is properly inflated and
not overloaded. Excessive speed, underinfla

Tire pressure monitoring
system
CD General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to
the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
bel, you shou ld determine
the proper tire infla
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell
tale when one or more of your tires
is significant
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them
to the proper pressure. Driving on a signifi
cantly under-inflated tire causes
the tire to over
heat and can lead to tire failure . Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect
the vehicle's handling and stop
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it
is the driver's re
spo nsibility
to maintain correct tire pressure,
even if under-inflation has
not reached the level
to trigger
illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function
indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction,
the telltale will flash for approxi
mately one minute and then remain continuously
illuminated. This sequence
will continue upon
subsequent vehicle start-ups as long as the mal
function exists.
When
the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions
may occur for a variety of reasons, including
