check oil AUDI A3 2016 Owner´s Manual

Checking and Filling
-If you have the impression your engine con ­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate measurement of oil consumpt ion
requires great care and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion acc urately.

ment.
Determining the oil level
• Park your vehicle on a level surface .
• Let the engine run in id le br iefly whi le it is at
operating temperature and the n shut the e n­
gine off .
• Wai t approx imately two m inutes .

• Remove the oil dipstick. Wipe off the oil dip­
stick with a clean cloth and insert it all the way
in aga in .
• Remove the dipstick again and then read the o il
level
¢ fig. 195 or ¢fig. 196.
• Evaluate the oil level¢ table on page 242. Add
eng ine oi l if necessary ¢
page 242.

Audi dealer or authorized Audi Service Fa-
cility immediately.
Applies to vehicles with a d iesel eng ine: fuel can
get into the engine o il if you run your vehicle with
biodiesel. This raises the o il level in the eng ine. It
also decreases the quality of the engine oil
¢page 24.
The oil consumption o f the engine may be up to
1/2 qua rt per 600 miles (0.5 l ite r per 1,000 km),
depending on d riving style and cond itions. Con­
sumption may be highe r during the firs t
3,000 miles (5,000 km) . Bec ause of this, the en­
gine o il level must be checked regularly.
It would
be best to check each time you refuel your veh icle
and before long drives .

tives is not covered by the warranty.
Checking and Filling
{® For the sake of the environment
-Oil shou ld never enter the sewer system or
come into contact with the ground.
- Pay attention to lega l requirements when
disposing of empty oil containers .
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
c::> page 236.
The engine o il must be changed according to the
intervals specified in your Warranty
& Mainte­
nance book let. This is very important because the
lubricating properties of oil diminish gradua lly
during norma l vehicle use.
Under some circumstances the engine oil shou ld
be changed more frequent ly. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traff ic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi dealer or
a qualified service stat ion.
If you choose to change your oil yourself, please
note the following important information:
A WARNING ,-~
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
243

Checking and Filling
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the total amount of oil in your engine .
- Engine oil is poisonous. Keep it well out of
the reach of children .
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
CD Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
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 sealed and generally re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixture of
244
specially conditioned water and the manufactur­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture
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 plain water.
The propor­
tion of coolant additive must be at least 50%
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-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 additive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
~ page 236.
CD 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 ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold.
If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive Gl2++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting

.... N

.... I.Cl U"I
.... I.Cl ....
corrosion can cause a loss of coolant and
serious engine damage .
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.

expa nsion tank
Read and follow the WARNINGS before check­
ing anything in the engine compartment
¢ page 236, Working in the engine compart­
ment.
Checking the engine coolant level
• Park your vehicle on a level surface .
• Switch the ignition off .
• Read the coolant level on the coolant expansion
tank
¢ fig. 198 . The coolant level must be be­
tween the markings when the engine in cold .
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive*: your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 108. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 109.
Requirement: there must be a residual amount of
coolant in the expansion tank ¢(D .
• Let the engine cool down .
Checking and Filling
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢ A .
• Add coolant mixed in the correct ratio
¢
page 244 up to the upper marking.
• Make sure that the fluid level remains stable.
Add more coolant if necessary.
• Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle to an authorized Audi dealer or au ­
thorized Audi Service Facility and have the cool­
i ng system inspected. If the cooling system is not
leak ing, a loss can come from the coolant boiling
through overheat ing and being pushed out of the
cooling system .
,&_ WARNING
-= -The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
with the engine hot. There is a risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex ­
haust system or hot engine components.
The ethylene glycol in engine coo lant can
catch fire under certain circumstances .
- The coolant additive and the coolant can be
dangerous to your health . For th is reason,
keep the coolant in the original container
away from children. There is a risk of poi­
soning .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, wh ich
increases the risk of persona l injury.
(J) Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the eng ine.
If this is the case, do not ..,_

Radiator fan
The radiator fan switches on outomotico/ly by it­
self.
An auxiliary elect ric radiator fan sw itches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fa n
can cont inue runn ing fo r up to 10 minutes -even
with the ignition off . It ca n even switch on again
later by itself¢.&. , if
- the temperature of the engine coolant r ises due
to the heat bu ild -up from the engine in the e n­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight .
A WARNING
-To reduce the risk of pe rsonal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the eng ine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coo lant reaches a
certain tempe rature and w ill cont inue to run
until the coolant temperature drops.

obstacles, drive slowly and ap ­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
... Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
... Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(D Note
-Please note that summer and winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ ­
er tires, which affects traction
Tires and wheels
and braking ab ility. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, result ing in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or sim ilar
substances.
