2016 AUDI A3 radiator cap

Driving
_& WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries.
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and brak.ing capa­
bility is not available, the risk of accidents or
injuries increases .
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine com­
partment is heated by the sun's rays and the
engine is hot.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off- there is a risk of damaging the
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.

Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
¢ .&. .
.8, WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns!
Wait until no steam or coolant flows out.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short circuits in the electrical system,
especially the battery.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en-
-
gine running, there is additional danger due ~

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.
Adding coolant
F ig . 198 Engine compa rtment: mark in gs on t he coo lant
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.

gent energy management system wi ll keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the additional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­
facture on ly (the same as those installed at the
time your veh icle was de livered). Specifications
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en ­
ergy management functions correctly after re­ p lacing the battery.
The new battery must have the same capacity,
voltage (12 -volts), amperage, construction and
p lug sealing .
When insta lling the battery, ma ke sure the igni­
tion and all e lectrical consumers are switched
off .
(D Note
Ma ke sure the ventilation hose on the side of
the battery is connected, otherw ise fumes o r
battery acid can leak out .
@ For the sake of the environment
Because of the prob lem of proper disposal of
a ba ttery, we recommend your author ized
Audi dea ler change the battery for you . Bat ­
teries contain su lf u ric acid and lead and must
always be disposed of properly in compliance
w ith all environmental regulations. D isposing
of vehicle batteries improperly is very danger­
ous to the env ironment.
