heating AUDI Q2 2021 Owner´s Manual

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

Closing the tank cap

•
Screw on the tank cap clockwise until
it
clicks
audibly.

•
Close the tank flap. Make sure you hear
it
click
into place.
When the automatic filler nozzle is operated cor­
rectly
it
will switch itself off
as
soon as the tank
is
fulL.
Do not try to put in more fuel after the
nozzle cuts out, as this will fill the expansion
chamber in the fuel tank.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel

A WARNING
Fuel is highly inflammable and can cause
seri­

ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis­
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area
oA-

A WARNING
- Switch off the engine.
-Switch off the ignition.

-Applythe
parking brake.
- On vehicles with manual gearbox place the
gear lever in neutral, on vehicles with auto­
matic gearbox move the selector lever to
position P.
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- Wait for the engine to cool down.
- Keep children away from engine compart­
ment.
- Never spill fluids on a hot engine. These
flu­

ids can cause a fire (e.g. radiator
anti­

freeze).
- Take care not to cause short circuits in the
electrical system.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off - risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.

Checking and topping up fluids
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the
fol­

lowing coolant additives. It is possible to mix
these additives.

The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too Low, the coolant
can freeze and cause engine damage.

CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­

pected.
This applies particularly if
you
drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­

ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

ment.
Checking coolant level

•
Park the vehicle on a level surface.

•
Switch off the ignition.

•
Read off the coolant level on the coolant ex­
pansion tank
^>Fig.
248. When the engine is

cold,
the coolant level should be between the
marks. When the engine is warm, it may be
slightly above the top mark.
Topping up coolant
Important: The coolant expansion tank must not
be empty
•=>([).

•
Wait for the engine to cool down.

•
Cover the cap on the expansion tank with a

cloth,
and carefully unscrew the cap
anti-clock­

wise
<=>
/K.

*-
Add coolant in the correct concentration

tapage
299 up to the top mark.

•
You should make sure that the fluid level re­
mains stable. If necessary, add more coolant.

•
Screw the cap on again tightly.
Any loss of coolant normally indicates a Leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system

checked.
If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.

Tow-
start
ing / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­

hicle.

Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is aLways a risk that the
anchorage points may be overloaded.
Tow-bar / tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
not have a tow-bar. It is advisable to use a tow-
rope made of elastic synthetic fibre or similarly
elastic material.
Notes on towing vehicles
The vehicle can be towed with a tow-bar or tow-

rope.
When the engine is not running, the
gear­

box will not be adequately lubricated if the
fol­

lowing speed/distance restrictions are not ob­

served:

- The vehicle must not be towed faster than
50 km/h.
- The vehicle must not be towed further than
50 km. •
