-To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter . The brakes
must be dried first w ith a few careful brake
applications.
(I) Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors. Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
f u nct ion.
- To prevent pa int damage, do not wash the
vehicle i n direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itche n
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax.
It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish pa int. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially de­
signed for that purpose. This will reduce the
risk of dirty water contam inated with o il from
entering the sewer system .
Placing your vehicle out

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side
c!,> page 193.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on
c!,> page 15 . Do not contin ue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an author iz ed
Aud i dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/ind icator light w ill illuminate .
Contact an authorized Audi dealer
i mmed iately .
{D) Tips
The brake fluid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moist ure from the a ir. 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 flu id
w ill also decrease conside rably and dec rease
b rak ing perfo rmance.
Therefore, the brake flu id must be changed
e ve ry
two year s.
Always use new brake fluid w hich con­
forms to Fede ral Motor Vehicle Standard "FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re , we recommend that you have the
b rake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct too ls , the
right brake fluid and the know-how to do t his for
you.
A WARNING
- B rake fluid is poisonous. It must be stored
on ly in the closed original container out of
the reach of children!
200
- Brake fail ure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau ­
tions:
- Use only b rake fluid that meets SAE spec i­
f ica tion
J 170 3 and conform s to Federa l
Motor Vehicle Standard 116. Always check
with yo ur autho rized Audi dea le r to make
su re you are using the correct brake fl uid.
The correct type of brake flu id is also ind i­
cated on the brake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake f luid 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 acc ident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the env ironment
Because of the prob lem of prope r disposal of
brake fluid as well as the special tools re­
qu ired and the necessary expert ise, we rec­
omme nd that you have the brake flu id
changed by you r autho rized Aud i dea le r.
Battery
, General information
U nder normal operating conditions, the battery
i n your Audi does not need any maintenance.
Wi th
high outside temperatures or long daily
drives we recommend that you have the e lectro ­
lyte level checked by an a uth orized Aud i deale r o r
qualified workshop . The electrolyte leve l should
a lso be checked each time the batte ry is c ha rged
c:!,> page 202.
Have the battery checked when yo u take your ve­
hicle in for service . You a re well adv ised to re­
pla ce a battery that is older tha n 5 years.
With certain types of airbag deployment, the bat ­
te ry is disconnected from the veh icle elect rical
system for safety reasons

and disposal of the airbags on page 1 42.

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
sponsibility 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
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle 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 the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS 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.

indicator appears
Appl ies to vehicles : wi th t ir e p ress ure mo nito rin g system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 172 Instrument cluster: i ndicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires .
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message .
If only one tire is affected, the location of that
tire will be indicated .
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢
page 224. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
r=> page215, fig.171.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low .
- the tire has structural damage.
- the tir e was replaced or the tire pressure was
changed and it was not stored ¢
