186 Checking and filling
Before you check anything in the engine com
partment,
alwa ys r ea d and heed all WARN
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration .
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in you r 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 ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec
ommend you check the coolant leve l 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 A udi 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.
@ Note
Do not add any type of ra diator leak seal
ant to yo ur vehicle's eng ine coolant. Add
ing radiator repair f luid 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 anyth ing in the engine com
partment,
always read and heed all WARN
INGS ¢ A in Working in the engine comport

tank
¢ page 185, fig . 141 and carefully

Replacement engine coolant must conform to
exact spec ificat ions
¢ page 185, Coolant.
E ven in a n emerge ncy, if coo lant addi -
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d ifferen t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amo unt o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
