overheating AUDI A3 2016 Owner´s Manual

Instruments and indicator lights
(+S °C), a snowflake symbol appears in front of
the temperature display.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en­
gine.
A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+S
0
()
and that ice can increase the risk of accidents .
@ Tips
You can change the measurement units, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ q page 10, fig. 3 only works when
the ignition is switched on. When the display has reached the reserve mark, the bottom LED will
turn red and the
tj] indicator light turns on
q page 24. Th e bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level~
page 29, On-board comput­
er display.
For the tank capacity in your vehicle , refer to the
Technical Data
qpoge 303.
(D Note
Never drive until the tank is completely emp­
ty . The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
t or, an indicator light . will turn on when the
12
coolant temperature is too high q page 20. Re­
fer to
q 0 .
The coolant temperature indicator @ q page 10,
fig. 3
only works when the ignition is switched
on. To prevent engine damage, please observe
the following notes about the temperature rang­
es .
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, full ac­
ce lerating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
T his is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
q page 20 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment . This increases the risk of
burns . Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area. Stop the engine and
allow it to cool before working in the engine
compartment. Always follow the informa­
tion found in¢
page 236, Working in the
engine comportment.
([) Note
-In vehicles with a boost pressure indicator*,
this indicator replaces the temperature dis­
play. To promote a long engine service life,

acceleration and heavy engine loads during
approximately the first 15 minutes when
the engine is cold is recommended. The
amount of time until the engine is warm de­
pends on the outside temperature. Check
the engine oil temperature* if necessary
¢ page 32.
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant . This increases
the risk of the engine overheating during
high outside temperatures and heavy en­
gine load.
- The front spoiler also he lps to distr ibute
cooling air correct ly wh ile driving. If the
spo iler is damaged, the cooling effect will
be impaired and the risk of the engine over ­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
@ Tips
Diesel engines: due to the high efficiency of
these engines, the engine may not always
reach operating temperature in cold outside
temperatures. This is normal and not a cause
for concern.

!?) Engine speed limitation
A pp lies to ve hicles : w ith e ngin e spee d limit ation
[II Max. engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the driver information system.
This protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature
range and you have released the accelerator ped­
al once.
If the engine speed limitation was activated by
an engine control malfunction, the
[m indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam­
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im­
mediately to have the malfunction corrected.

Driving
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­ ronment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi ­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed .
Accelerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­ ment.
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half . Never drive faster than the posted
speed limit and weather conditions permit.
78
· Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the engine off when you are not driving
the vehicle .
.,. Do not warm up the vehicle by letting the en-
gine run at idle .
It is efficient to switch off the engine when stop­
ped at railroad crossings and long red lights.
Turning the engine off for just 30 -40 seconds
saves more fuel than is burned by starting the
engine again .
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially high when
the engine is warming up . So you should drive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up .
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs properly
and economically. The condition of your vehicle
not only affects its safety and ability to hold its
value, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile -
age has been driven . ..,.

The cata lytic converter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A 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 i n burns .
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire .
-Do not apply additional undercoating or
rustproofing o n or near the exhaust mani­
fold, exhaust pipes, catalytic converte r o r
heat s hields. During dr iving, t he substance
used for under coati ng could ove rheat and
c ause a fire.
(D Note
- Be aware that just one tank filling with
leaded fue l wi ll al ready ser iously degrade
the pe rformance of the ca talytic converter.
- Do not ex ceed the correct eng ine o il level
~page 242.
- Do not d rive until the fuel tank becomes
complete ly empty. The engine co uld m is­
fire. Unburned fuel could also get in to the
exhaust system and this co uld cause t he
cata lytic converter to overheat .
- Do no t sw itch off t he igni tion while t he vehi­
cle is moving.
- Do no t continue to operate your vehicle un­
der these cond it ions, as othe rwise fue l can
reach the catalytic converter. This cou ld re ­
su lt in overheating of the converter, req uir­
i ng its replacement.
Ch eck ing and Filling
-To ass ure eff icient operat ion of the Emis ­
sion Contro l System:
- Have yo ur vehicle maintained p roperly and
i n accordance with the serv ice recommen­
dat ions in yo ur War ranty

~ For the sake of the environment
Eve n when the Em iss ion Control System is op­
era ting properly, t he exhaus t gas can have a

content of the fuel being used. Using a differ­
ent brand of fuel may help, or fi lling the tank
with lead-free super grade gasoline.
Diesel particulate filter
Appl ies to vehicles: wit h diesel eng ine
The diese l particu late filter filte rs nearly all of
the soot part icles out of the exhaust. The filter
cleans itself automatically under norma l driving
