220 Vehicle care and cleaning
-Wheels
-Never use any paint polish or other
abrasive materials.
- Damage to the protective layer on the
rims such as stone chips or scratches
must be repaired immediately.
- Sensors/camera lenses
- Never use warm or hot water to re-
move snow or ice from the camera
lens. This could cause the lens to crack.
- Never use abrasive cleaning materials
or alcohol to clean the camera lens.
This could cause scratches and cracks.
-Windows
- Remove snow and ice on windows and
exterior mirrors with a plastic scraper.
To avoid scratches, move the scraper only in one direction and not back and
forth.
- Never remove snow or ice from win­
dows and mirrors using warm or hot
water because this could cause cracks
to form.
- To avoid damage to the rear window
defogger, do not apply any stickers on
the heating wires on the inside of the
window.
- Decorative parts/trim
- Never use chrome care or cleaning
products.
- Paint
-To reduce the risk of scratches, the ve-
hicle must be free of dirt and dust be­
fore polishing or waxing.
- To prevent paint damage, do not polish
or wax the vehicle in direct sunlight.
- To reduce the risk of paint damage, do
not polish away rust film.
- Trim
- To reduce the risk of damage, do not
treat the trim around the panorama
sunroof with paint polish.
- Decorative decals
-To reduce the risk of damage, do not
use any rough powder or abrasive

trols, because this could cause dam­
age.
- Safety belts

them.
- Never clean safety belts or their com­
ponents chemically or with corrosive
fluids or solvents and never allow

hard sponges, etc. when cleaning.
- Objects with sharp edges such as zip­
pers, rivets on clothing or belts can
cause damage to the surface.

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 204 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com­
partment,
a lwa ys re ad and h eed a ll WA RN­
INGS o .A in Working in the engine compart­
ment on page 231 .
Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the engine coolant leve l from the cool­
ant expansion tank
o fig. 204, o page 233.
With a cold engine, the coolant level should
be betwee n the "min" and "max" markings.
When the engine is warm, the level may be slightly above the "max" marking .
The location of the coolant expans ion tank
can be seen in the engine compartment illus ­
tration
o page 233.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
o page 16 wi ll
illuminate unti l 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 l oss
Coolant loss may indicate a le ak in the cooling
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coo lant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot. Red uce the risk of scald­
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying light, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, the ethylene glycol in engine cool­
ant can catch fire.
0 Note
Do not add any type of radiator leak seal­
ant to your veh icle's engine coolant . Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct io n 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 anyth ing in the eng ine com­
partment,
alw ay s re ad and h eed all WARN­
IN GS o .A in Working in the engine compart­
ment on page 231.
• Tu rnoff the engi ne.
• Let the eng ine cool down.

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intend ed . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels 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
Applies 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. 213 Display : underi nflatio n warning
Fig. 214 Di splay: Syste m mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration ch arac teristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru-
Tires and wheels 267
ment cluster with a warning symbol [I] and a
message
r::!) fig. 213.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad ­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
r::!) pag e 268. 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
<=:>page 252 .
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
r::!) page 268 .

Check the tire or tires and replace or repair if
necessary. The indicator light

ment cluster also illuminates

turn off or if it turns on shortly thereafter, im­
mediately drive your vehicle to an authorized
Audi dealer or authorized repair facility to
