-Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti
freeze or coolant on the exhaust system or hot engine parts. Under certain condi
tions, the ethylene glycol in engine cool
ant can catch fire .
- Antifreeze is poisonous. Always store anti
freeze in its original container and well out of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
CD Note
-Coolant pollutes the environment and could
cause an engine fire . Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
-If, in an emergency, only water can be add
ed, the correct ratio between water and an
tifreeze

soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor
rosion in the brake system may result after a peri
od of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
164
Brake fluid is replaced according to the Audi
maintenance service schedule . Your authorized
Audi dealer is equipped with the necessary spe
cial tools and replacement parts, has the neces
sary expertise, and can dispose of the used fluid .
A WARNING
-Brake fluid is poisonous . It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro priate brake fluid. Observe these precau
tions:
- Use only brake fluid that meets SAE speci
fication
J 1703 and conforms to Federal
Motor Vehicle Standard
116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake fluid is also indi cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the brake fluid is left in the system too long.
This can seriously affect the efficiency
of
the brakes as well as your safety . This
could result in an accident.
CD Note
Brake fluid will damage the paint of your vehi
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re
quired and the necessary expertise, we rec
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information '
Your vehicle is equipped with a special battery, an
ACM battery . This battery is located in the lug
gage compartment and must be replaced with an
original equipment battery. Under normal oper
ating conditions, the battery is
maintenance-
free. ..,_
..... N
r-N "': ..... \!) 1.1'1
N 1.1'1 .....
Have the battery checked when you take your ve
hicle in for service. You are well advised to re
place a battery that is older than 5 years .
Disconnecting the batt ery terminal s
Some vehicle funct ions (power w indow regula
tors , fo r example) are lost if the battery termi
na ls are disconnected. These functions have to be
re learned after the battery terminals are con
nected again. To prevent this , the batte ry shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
V ehicl es not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period of
several days or weeks , e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains s tarting ca
pability over a longer period<=> page 140. Some
of the convenience funct ions may not operate ,
such as the inter ior lights or powe r seat ad just
ment. The convenience functions will be ava ilable
again when you switch on the ignition and start
the eng ine.
Wint er op erati on
During the winter months, battery capacity tends
to decrease as temperatures drop . This is because
more power is also consumed w hile start ing , and
the head lights, rear w indow defogger, etc., are
used more often.
Avoid unnecessary power consumption, part icu
l arly in city traffic o r when traveling only short
d ista nces . Let you r a utho rized Aud i dea le r check
the capacity of the vehicle battery before w inter
sets in <=> page 167. A well charged battery will
not on ly prevent starting prob lems when the
w eather is cold, but will also last longer.
R eplacing battery
The new battery mu st ha ve the same capacity,
voltage
(12 vo lts), amperage, construction and
p lug sealing, as the original battery . Specifica
tions are listed on the battery housing. Batteries
specia lly deve loped by Audi fulfill the mainte
nance, output, and safety requ irements .
Check ing and fillin g
When installing the battery, make sure the igni
tion and all electrica l consumers are switched off

When the malfunction indicator is illuminated,
the system may not be able to detect or signa l
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of rep lacement or a lternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
T PMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly .
Introduction
The tire pressure monitoring system monitors air
pressure in all four road wheels while the vehicle
is moving.
As soon as the tire pressure monitoring system
senses a s ignificant loss of a ir pressure in one or
several tires, text messages and ye llow symbo ls
appear in the instrument cluster display to a le rt
the driver. The
[I] warning light in the instru
ment cluster comes on when the tire is signifi
cantly underinflated .
The warning
light [l'J also illuminates in the case
of a system malfunction.
Be aware that tire p ressure is also dependent on
the temperat ure of the t ire. For every 18 ° F
(10 °() increase in tire temperature, tire pressure
increases by about 1.5 psi (0.1 bar) . The tire
warms up while the vehicle is moving and tire
pressure rises. So you shou ld adjust tire pressure
only when they are
cold, when the temperature
of the tires is roughly the same as the ambient
air temperature.
In order to keep the tire pressure monitoring sys
tem properly calibrated, tire pressure on all four
tires should be checked at regular intervals .
The tire pressure is shown on the label located on
~ the driver 's side B-pillar (visible when the door is r--
~ open) .

A WARNING
-
When the tire pressure monitoring system
warning light is lit, one or more of your tires is
significantly under- inflated . You should stop
and check your t ires as soon as poss ible, and
i nflate them to the proper pressure as indicat
ed on the vehicle 's t ire pressure label
¢ page 176. Driving on a significant ly under
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also is
likely to impair the vehicle's handling and
stopping ability.
@ For the sake of the environment
Driving with under -inflated tires reduces fuel
efficiency and tire tread life.
(D Tips
- Each tire should be checked monthly when
the temperature of the tires is about the
same as ambient air temperature and set to
the recommended inflation pressure as
specified on the tire pressure label
¢page 176.
- The tire pressure mon itoring system helps
the driver to keep an eye on tire pressures.
But the driver still has the responsib ility for
ma inta ining the correct tire pressure.
- Tire pressure must only be adjusted when
the temperature of the tires is about the
same as amb ient air temperature.
- When tires are replaced, the sensors and
valves should not be exchanged. The valve
core, nut, valve seal ing and seal washer (re
placement kit) needs to be replaced. If nec
essary, the valve and the wheel electronics
have to be replaced.
- The tire pressure mon itoring system on your
Audi was calibrated using tires with "RO"
identification. We recommend using these
tires .
- If you sho uld put different wheels and tires
on your vehicle (e .g. winter whee ls and
tires), you must be certain that the wheels
197
Tires and wheels
and tires are compatible with the tire pres
sure monitoring system. Otherwise the sys
tem will register a malfunction and a fault message will be displayed. For more infor
mation, contact your authorized Audi deal
er.

- Do not store the tire pressure if there are
snow chains on the tire.
TPMS Tire pressure monitoring system
malfunction
A malfunction can have various causes.
If the [I] warning light in the instrument cluster
flashes for approximately one minute and then
remains continuously illuminated and additional
ly
the m symbol appears in the display, the tire
pressure monitoring system is not available. The
198
text Tire pressure! System malfunction appears
in the display. This can have various causes.
- A wheel sensor or other component may have
fai led.
- During initialization the system has detected
more than 4 wheels on the vehicle, for example
while driving next to another car with a tire pressure monitoring system.
- Audi replacement parts were not used.
- If snow cha ins are being used, system function
can be compromised due to the shielding prop
erties of the chains .
- The tire pressure monitoring system may not
be available because of a rad io malfunction.
- Transmitters with the same frequency, such as
radio headphones in the vehicle or radio equip
ment, can cause a temporary disruption of the
system through excessive electromagnetic
fields .
- Eliminate the interference if you can and then
proceed as follows: Turn off the engine for 20
minutes. Then drive another 10 minutes.
If the
warning light comes on again, you should con
tact your authorized Audi dealer immediately
to have the problem corrected.
- Do not use commercially available tire sealants.
Otherwise, the electrical components of the
tire pressure monitoring system will no longer
work properly and the sensor for the tire pres
sure monitoring system will have to be replaced
by a qualified workshop.
