Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 134 Eng ine compartme nt: cover o n the coolant
expansion tank
Before you check anything in the engine com
partment,
a lway s read and he ed all WARN
INGS ¢ A in Working in the engine compart
ment on page 165.
.,. Park your vehicle on a level surface.
.,. Switch the ignition
off .
.,. Read the coola nt level at the coolant expan
s ion tank
¢ page 167, fig . 130. With a cold
engine, it must be above the "min" mark.
With a hot engine, it can be a l ittle above
the indica ted range.
The location of the coolant expans ion tank
can be seen in the engine compar tment illus
tration
¢page 167.
To obtain an accurate read ing, the eng ine
must be switched
off.
The expans ion tank in your vehicle is equipped
with a n electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System¢
page 17 will
illum inate 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 leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool
i ng system should be inspected immediately
Checkin g and fillin g 173
by your authorized Audi dea ler . It is not
enough merely to add coo lant .
In a
s ealed system, losses can o ccu r on ly if
the boiling point o f the coo lant is exceeded as
a res ult of overheating.
(D Note
Do not ad d any type of radiator leak sea l
ant to your veh icle's engine coo lant. Add
ing radiator repa ir flui d may adverse ly af
fect the function and performance of yo ur
cooling system and could result in damage
not covered by your New Vehicle Limited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com
partment,
alway s read and heed alt WARN

.,. Twist the cap on aga in tightly.
Rep lacement engine coo lant must conform to
exact specificat ions¢
page 172, Coolant.
We recommend using only coolant add itive
Gl2 ++, Gl3 or in an emergency Gl2+. Do not
use a different additive. In an emergency use
plain water until you can get the correct addi
tive and can resto re the correct ratio . Th is
shou ld be done as soon as possib le.
If you have lost a cons iderab le amount of
coolant, then you should add cold ant ifreeze
and co ld wate r on ly 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 fo rced o ut through the ..,_

200 Tires and wheels
remain continuo usly illuminated . This se
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunction 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 alternate tires or wheels on the vehi
cle that prevent the TPMS from functioning properly . Always check the TPMS malfunction
tellta le after replacing one or more t ires or
wheels on your veh icle 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.
F ig. 143 Display : underi nflat io n warn ing
Using the ABS sensors, the tire pressure moni
toring sys tem compares the t ire tread circum
ference and vibration characteristics of the in
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru
ment clus ter with a warning symbo l
ail and a
message<>
fig. 143. The dr iver message in the
display goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on
l y one tire is affected, the display will indicate
its pos ition.
The tire press ure monitoring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti- al and fu
ll load pressure) or after changing or
replacing a tire on your vehicle<>
page 201.
The TPMS indicator only mon itors the t ire
pressure that you have previously stored . You
can find the recommended tire pressures for
your vehicle on the label on the driver's door
pillar
¢ page 185.
Tire tread circumference and vibration charac
teristics can change and cause a tire pressure
warning if:
- the t ire 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
¢ page 201.
Warning symbols
ail Loss of pressure in at least one tire¢& .
Check the tire or tires and replace or repa ir if
necessary . The indicator light
HE in the instru
ment cluster also illuminates
<>page 13.
Check/correct the pressures of all four tires
and reset TPMS in the menu display .
ffim (T ire Pressure Monitoring System) Tire
pressure! System malfunction. Ifffim
ap
pears after switching the ignition on or while
driv ing and the indicator lig ht
HE in the in
strument cluster blinks for approx ima tely one
minute and then stays on, there is a system
malfunction .
At tempt to store the correct tire pressure
¢ page 201. Ifthe indicator light does not
turn
off or if it turns on shortly thereafter, im
med iate ly drive your vehicle to an author ized
Audi dealer or author ized repair facility to
have the malfunction corrected.
_&. WARNING
-
- If the tire pressure indicat or appears in
the instrument cluster display, one or
more of your tires is significant ly under
inflated . Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures.
