2020 AUDI A3 open gas tank

8V2012721BK
Checking and Filling

— Do not use any gasoline mixture whose
composition cannot be identified.
— Audi does not assume any responsibility for
damage to the fuel system or for perform-
ance problems caused by using gasoline
mixtures different from those specified.
This type of damage also does not fall under
the New Vehicle Limited Warranty or under
the emissions control system warranty.
— If you notice a higher fuel consumption or
poor handling or performance problems due
to such gasoline mixtures, we recommend
fueling with unblended gasoline.
Gasoline additives
An important issue for many automobile manu-
facturers is combustion residue in the engine
that results from the use of certain fuels.
Although types of gasoline differ depending on
the manufacturer, there are similarities. Certain
substances in the gasoline may cause deposits in
the engine. Additives in the gasoline that should
keep the engine and fuel system clean do not all
function equally.
Audi recommends using TOP TIER Detergent Gas-
oline. For additional information on TOP TIER De-
tergent Gasoline, visit www.toptiergas.com.
If you use incorrect fuels over a long period of
time, the maximum engine performance may be
impaired by combustion residue.
@) Note
— Damage or malfunctions caused by the use
of incorrect types of gasoline are not cov-
ered by the New Vehicle Limited Warranty.
— Only gasoline additives that have been ap-
proved by Audi may be used.

Emissions control
system
(ee eileen)
ZX WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
— Never touch the exhaust tail pipes once they
have become hot. This could result in burns.

— Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the emissions sys-
tem could start a fire.

— Do not apply underbody protectant in the
exhaust system area, because this increases
the risk of fire.
(el e-] Nad (mcl akg
Follow the safety precautions > page 303, Gener-
al information.


The vehicle may only be driven with unleaded
gasoline, or the catalytic converter will be de-
stroyed.
Never drive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel
could enter the exhaust system, which could
cause overheating and damage to the catalytic
converter.
On Board Diagnostic System (OBD)
The On Board Diagnostic System monitors the
engine and transmission components that influ-
ence emissions.

port for the On Board Diagnostic System (OBD)
On Board Diagnostic System
Engine data can be read out at the On Board Di-
agnostic System connection port using a special
testing device > fig. 245.
Indicator light
If the S indicator light blinks or turns on, there
is a malfunction that is causing poor emissions
quality and that could damage the catalytic con-
verter. Drive slowly to an authorized Audi dealer >

Checking and Filling

Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en-
gine. If this happens, only use water and re-
store the correct mixture ratio with the
specified coolant additive as soon as possi-
ble.
— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide you with important information about
the recommended coolant additive.
@® Tips
Applies to: RS models: In certain weather
conditions, moisture such as rain or snow may
evaporate on the radiator after stopping the
vehicle. This may cause steam to escape from
the front of the vehicle.
Applies to: vehicles with plug-in hybrid drive


Fig. 251 Engine compartment: coolant expansion tank
Your vehicle has two coolant expansion tanks
that are separate from each other:
@) expansion tank for gasoline engine and elec-
tric motor.
@®): expansion tank for the high-voltage area.
312
The expansion tank (@) must not be opened
oA.
> Switch the ignition off.
> Open the hood > page 305.
> Always check the coolant level in both coolant
expansion tanks (@) and @) using the outer
markings.
> When you fill coolant in the expansion tank (A),
please refer to > page 311, Cooling system.
> Do not drive any farther if the coolant level in
the expansion tank (@) is low. Contact an au-
thorized Audi dealer or authorized Audi Service
Facility immediately > A\.

ZA WARNING
— Read and follow the warnings in
=> page 304, General information before
opening the hood and checking the coolant
level.
— The expansion tank (8) may only be opened
and filled by an authorized Audi dealer or
authorized Audi Service Facility.
— Coolant can enter the inside of the high-
voltage battery when filling the expansion
tank @) and cause a short circuit, which in-
creases the risk of fire.
