engine coolant AUDI A4 2016 User Guide

Check ing and F illing
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow legal regulations when
disposing of empty oil containers .
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you che ck anything in the eng ine compart ­
ment,
always read and heed all WARNINGS ¢ A
in Working in the engine comportment on
page 203.
The engine oil must be changed according to the i n tervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circ umstances the eng ine oi l sho uld
be changed more frequently. Change oil more of­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions , or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after t he engine has been run ning for a
short t ime . T his is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the prob lem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil c hanged by an aut ho rized
Audi dealer o r
a qualif ied se rvice station .
If you choose to change your o il yourself , please
note the following important informat ion:
A WARNING
To re duce the risk of pe rsonal injury if you
must c hange t he engine oil in your ve hicle
yo urs elf:
- W ear eye protection .
208
-
-To reduce the r is k of burns from hot engine
oil, let the engine cool down to the touch .
- W hen removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm pa rallel to the ground to
he lp prevent hot oil from run ning down your
arm .
- Drain t he oil into a container designed for
this purpose, one large enough to hold at
leas t the tota l amou nt of oil in you r engine.
- Engi ne oil is poisonous . Keep it well out of
the reach of childre n.
- Continuous contact wit h used engine o il is
ha rmf ul to your skin. Always protect your
skin by washi ng oil
off thoroughly with soap
and wate r.
(D Note
Neve r mix oil additives with yo ur engine oil.
These additives can damage your e ngine and
adverse ly affect your A udi L imi ted New Vehi ­
cle Warranty .
@ For the sake of the environment
-Be fore chang ing you r oi l, first make sure
you know where you can properly dispose o f
t h e used oil.
- Always dispose of used e ngine o il pro perly .
Do not d ump it on garden so il, wooded
areas, into op en streams o r down sewage
drains.
- Recycle used e ngine o il by tak ing it to a used

Cooling system
Coolant '
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from free zing in the winter.
The coolin g system is sealed and generally re­
quires little attention .
The coo lin g sys tem h as been filled a t the fac to ry
wi th a pe rmanent coolan t which does not need to
be changed. The coo lant consists of a mixture of .,.

..... N
0 ::..:: co ..... ..... specially conditioned water and the man ufactur­
er's g lycol-bas edcoo lant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
e ls; 60% for Canadian models). This m ixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling.
It also
raises the boiling point of the coolant .
Do not reduce the concentration of the coolant in
the summer by adding p lain water .
The propor­
tion of coolant addit ive must be at l eas t 50° /4
but not more th an 60 %
to maintain antifreeze
p rotection and cooling effic iency. If the coolant
frost protec tion is too low, the coolant co uld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at 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 water
and coolant addit ive. Mixing the coolant additive
with d istilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS
Q &. in Working in the engine compart­
ment on page 203.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions. This is especially important if you
li ve in a reg ion where the w inte r is ext reme­
l y co ld. If ne cessary, in cre ase the proport io n
of coo lant add itive to 60%.
- When addi ng coolant addit ive to you r cool­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2 ++ or Gl3 for your ve hicle. T his
coolant additive is available at authorized
Audi dea lers. Othe r types of antifreeze can
significant ly reduce cor ros ion p rotection .
Ch eck ing and Filling
The resulting co rrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator lea k sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
F ig. 184 En gin e co mpa rt men t: Cover o n the coo la nt ex ­
pans ion t ank
.. Before you check anything in the eng ine com ­
partment,
al ways read and heed all WARN ­
INGS
q ..&. in Working in the engine compart­
ment on page 203 .
.. Park your ve hicle on a leve l sur face .
.. Tu rn off the ignit io n .
.. Read the eng ine coolan t level from the coo lant
expansion tank
q fig . 184, Q page 205,
fig. 181 .
With a cold engine, the coolant level
should be between the " MIN" and "MAX" mark­
ings. When the engine is warm, the level may
be slightly above the "MAX" marking.
The location of the coo lant expansion tank can be
seen in the engine compartment illustration
q page 205.
To obtain an accurate reading, the engine must
be switched off.
T he expansion ta nk in your veh icle is eq uipped
with an electric coo lant level senso r.
When the coolant leve l is too low , the warning
light i n the Auto-Check System
Q page 17 will
209

Check ing and F illing
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction wh ile apply ing
l ight, 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 eng ine parts . Under certain conditions,
the ethy lene g lycol i n engine coolant can
catch fire.
{Q) Note
Do not add any type of radiator leak seala nt
to your veh icle's engine coolant . Adding radia­
to r repa ir fluid may adversely affec t the func­
tion and performance of yo ur cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
Adding coolant

-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.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the engine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
c::> page 208 must be restored as
soon as possible.
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
belt . The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary electric radiator fan* switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
Checking and Filling
with the ignition off. It can even switch on again
later by itself
c::> & , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

..... N
0 ::..:: co ..... ..... today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicab le text and careful­
ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS

ment on page 203 .
Consumer information
A WARNING
-Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or any
properly equipped and qualified workshop.
- The engine compartment of any motor vehi­
cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
gine is off and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one gets under the vehicle.
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in "P"
(Park position) or Neutral (manual transmis-
sion) and the park brake is firmly applied . ..,.
