cooling AUDI Q5 2014 User Guide

238 Check ing and filling
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden so il, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q ui res little attention .
The cooling system has been filled at the fac­
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion addi­
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil­
i ng po int of the coo lant .
Do not red uce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficie n­
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35° C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .

Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS~ .&.
in Working in the engine
compor tment on page 231 .
(J;) Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in
yo ur vehicle is sufficient to meet the cli­
mate condi tions . This is especia lly impor ­
tant if you live in a region where the win ­
ter is extreme ly co ld . If necessary, in­
crease the p roportion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
cooling system, remember :
- W e r ecommend using o nly coola nt ad­
d itive G l2++ or Gl3 for your veh icle.
T his coolan t additive is av ail ab le a t au­
thor ized Audi dealers. O ther types of
antifreeze can significant ly reduce cor ­
rosion protection . The resulti ng cor ro­
sion can cause a loss o f coolant and se­
rious engine damage.
- Do not add any type of rad iator leak seal ­
ant to your vehicle 's eng ine coolant.
Add ing radiato r repair flu id may adverse­
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not cover ed by yo ur New Ve hicle
Limited Warranty.

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

exp ansion tank
Before you check anything in the engine com­
partment,
a lway s re ad and he ed all WARN ­
INGS ¢ A in Working in the engine compart­
ment on page 231 .
.,. Park your vehicle on a level surface.
.,. Turn off t he ignit ion.
.,. Read the eng ine coolant level from the cool­
ant expansion tank¢ fig . 201, ¢ page 233,
fig. 198 . With a cold eng ine , the coola nt
level should be between the "M IN " and
"MAX" markings . W hen the eng ine is warm,
the leve l may be slightly above the "MAX"
marking.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢page 233.
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in your vehicle is equipped
with an e lectr ic coolant level sensor .
When the coo lant level is too low, the warning
light in the Auto -Check System ¢ page 30 will
blink until you add coo lant and the level has
been restored to normal. Even though there is
a n elec tric coolant leve l sensor, we s till rec­
ommend you chec k 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-
Checkin g and fillin g 239
ing system shou ld be inspected immediately
by your authorized Audi dealer . It is not
eno ugh merely to add coo lant .
In a
s ealed system, losses can occu r on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
(D Note
Do not a dd any type o f radiator leak se al­
ant to your veh icle's engine coo lant. Add ­
ing radiator repa ir flui d may adverse ly af­
fect the funct ion and performance of yo ur
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 alt WARN­
INGS ¢ A in Working in the engine compart ­
ment on page 231 .
.,. Turn off the engine .
.,. Let the engine cool down.
.,. Place a thick rag over the coo lant expansion
tank ¢ page 239, fig. 201 and
carefully turn
the cap counter -clockwise ¢
_& .
.,. Add coolant m ixed in the co rrect rat io
¢ page 238, Coolant.
.,. Twis t the cap o n aga in tightly.
Rep lacement engine coo lant must conform to
exact spec ificat ions ¢ page 238, Coolant.
We recommend using only coolant add itive
Gl2 ++, Gl3 or in an emergency Gl2 +. Do not
use a different add itive . In an emergency use
plain water until you can get the correct addi­
tive and can restore t he cor rect ratio . Th is
sho uld be done as soon as possib le.
If you have lost a cons iderab le amount of
coolant, then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the eng ine is cold.
Always use new engine coo lant when refill ing .
Do not fi ll coo lant above the "MAX" mark. Ex­
cess coolant will be forced o ut through the
