This also applies to cleaning headlights
and painted bumpers. Remember: the
closer the nozzle is to the surface of the
material, the greater the stress on the ma­
terial.
Caring for vehicles with matte finish
paint
Ap plies to vehicles: with matte fi nish pa in t
Vehicles with matte finish paint require spe­
cial care due to the characteristics of the
paint.
Washing by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger ­
prints are best removed with a
special cleaner
for matte finish paint.
Apply the product using a microfiber cloth . To
avoid damaging the paint surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water . Clean
the vehicle starting at the top and working to­
ward the bottom using a
neutral shampoo
and a soft microfiber cloth . Stop frequently to
rinse the cloth thoroughly .
Clean the wheels and sill panels last. Use a
clean
sponge on these areas.
Rinse the vehicle thoroughly again and let it
air dry. If there are any water spots, they can
be removed using a
leather cloth.
Clean again with the special cleaner for matte
finish paint
if necessary.
Removing stubborn dirt
Bird droppings or tree sap
are best removed
with plenty of water and a microfiber cloth.
You should rinse off
gasoline residue immedi­
ately with plenty of water.
_& WARNING
- Wash your vehicle only when the ignition
is switched off to reduce the risk of a
crash. -
Always read and heed all WARNINGS and
other information ¢
page 215.
@ Note
-Do not treat vehicle parts painted with
matte finish paint using polishing mate­
rials or hard wax. These products could
cause damage to the appearance or sur­
face that cannot be repaired.
- 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 paint. The paint could be
damaged when the stickers or magnets
are removed .
- To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To prevent damage to the paint surface,
do not use insect removal sponges,
rough kitchen sponges or similar items.
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle . Only clean the head­
lights using a wet cloth or sponge, never
a dry one. Cleaning with soapy water is
recommended.

' Sensors and camera lenses
- Remove snow with a hand brush and remove
ice with a de-icing spray that does not con­
tain solvents.
- Clean the sensors (adaptive cruise control*,
parking system*) with a cleaning solution
that does not contain solvents and a soft
cloth.
- Dampen the camera lens with a household alcohol-based glass cleaner, and then wipe
the lens clean with a dry cloth . The area in
front of the camera lens is normally cleaned
by the windshield wipers (lane assist*) or .,.

headlight washer system (night vis ion as ­
sist*) .
If the area is heavily soi led, you can
clean it with glass clean ing agent and a soft,
dry cloth.
(D Note
- If you wash your vehicle with a pressure
washer,
- make sure there is enough d istance to
sensors in the rear bumper .
- do not clean the camera lenses and the area around them with the pressure
washer.
- Never use warm or hot water to remove
snow or ice from the camera lens . Th is
could cause the lens to c rac k.
- Neve r clean the came ra lens w it h abra­
s ive p roducts.
Waxing and Polishing
Waxing
A good wax coat ing protects the ve hicle pa int
to a large extent aga inst the environmen tal
factors listed under
r::o page 215, Washing and
even against slight scratches .
You can use a liquid ca r wax to p rotect your
pa int as soo n as o ne week after your veh icle
h as been de livered .
Even if you regular ly use a
waxing process in
automatic ca r washes, we recommend t hat
you ma nually app ly a coat of wax to give the
pa int extra protec tion , particula rly if wate r no
l onge r beads on the clean paint .
P rotect p lastic body pa rts with ca r wax i n the
same way as the vehicle body.
During warm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood . They a re much easier
to remove from pai nt tha t is waxed
often.
Polishing
Poli sh your vehicle only if the pa int has lost its
shine and the gloss cannot be brought back
with wax .
Cleaning and protec tion 219
If the po lish used does not contain p reserva­
tive compounds, the paint must be waxed af­
terwards.

([) Note
Do not use car wax on
- matte or anodized meta l trim
- ru bber or ru bber- lik e t rim.
Trim strips
Metal trim needs special care.
For environmental reasons, Audi fabric ates
the bright t rim strips and trim p ieces from
pure chromium-free al uminum .
Dirt and marks on the trim strips shou ld be
removed w ith a
pH-balanced cleaning agent
(do not use a chrome cleane r) . Aud i dealers
carry clean ing produc ts which have been test­
ed fo r use on your vehicle and are not ha rmfu l
to the environment.
T o avoid co rrosion on the exter ior trim st rips,
o nly a pH-ba lanced solu tion should be used
for the windsh ield washer.

the level may be slightly above the "max"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 234.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
¢page 16will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor , we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying 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 .
Checking and filling 241
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com ­
partment,
always read and heed all WARN­
INGS ¢ & in Working in the engine compart ­
ment on page 232 .
.,. Turn off the engine .
.,. let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢
page 240, fig . 200 and carefully
twist the cap counter-clockwise ¢&_ .
.,. Add coolant.
.,. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive G12+
+, G3 or in an emergency G12+. Do
not use a
different additive. In an emergency use plain
water until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of

268 Tires and wheels
and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists.
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or a lternate tires or whee ls on the vehi­
cle 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 re­ placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
App lies to vehicles: with tire pressure monitoring 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. 209 Display: underinflation warning
Fig. 210 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni ­
toring system compares the tire tread cir cum­
ference and vibration character istics of the in ­
dividua l tires. If the pressure decreases in one
o r more t ires, this is ind icated in the instru­
ment cluster with a warning symbol
[«E and a
message ~
fig. 209.
The tire pressure monitoring system must be
reset via MMI each t ime the press ures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
c::> page 269. The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
c::> page 2 53.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage ,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
c::> page269.
