2016 AUDI A3 warning

Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
- Plug-in hybrid drive* climate control
¢page 122
The climate control system* cools and removes
humidity from the air in the vehicle interior. It is
the most effective when the windows and panor­
ama sunroof* are closed.
If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process. For this reason, the
windows and panorama sunroof can be opened from the outside .
¢ page 43, Convenience open­
ing/closing
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air .
Key recognition
You can store various settings for the manual and
automatic
climate control system* and assign
them to the key being used.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the cl imate
control system, especially with the defrost­
ing and defogg ing function.
- When the temperature is below freezing,
only use the windshield washer system after
70
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty.
Cl) Note
- If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Aud i dealer
or authorized Aud i Service Facility .
@ For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
dr ip and form a puddle of water unde r the
vehicle. This is norma l and does not mean
there is a leak.
- Th e energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy supply has been
restored.
- The f lows through the vents under the rear

Engine preheater
Applies to vehicles: wi th engine prehea te r
( )
Fig. 75 Left fron t bump er: connecto r socke t@ for th e en ·
gine prehea ter
T he engine preheater s lowly warms the engine
coolant using a heating element when the vehicle
is parked. For this function, the cable provided
must be connected to a 120 Volt socket that is
protected from water and t hat is grounded a nd
equipped with a GFI circu it breaker, for example
in a ga rage. The engine reaches operating tem­
perature much more quickly afte r sta rting when
t h e coolant is preheated . This reduces fuel con­
s u mption and exha ust emissions dur ing the
warm-up phase.
Preheat ing the engine can take up to 3 hours de­
pend ing on the temperature o utside.
Connecting the engine preheat er
- Only use the connector cable provided and a
suitable extension cord, if necessary .
- All cables and connectors that are used must not be damaged
~ li::,. .
-Open the cover(!).
- Plug the connector cable into the socket @.
- If necessary, plug the connector cable into the
extension cord. Only use highly durab le exten­
sion co rds that are class 12 or better and can
be properly grounded to a three-prong wall
socket with a GFI circuit breaker and that are
not longe r than 100 feet (30 meters) .
- Plug the connector cable or extension cord into
a grounded 120 Volt wall socket that is pro­
tected by a GFI circuit breaker and that is pro­
tected against rain and other moisture. Never p lug the engine preheater into a conventiona l .._

.&_ WARNING
Using the engine preheater incorrectly can
cause short circuits, electric shocks, fire, seri­
ous injuries and death.
- The connector cable must always be con­
nected to a grounded 120 Volt socket that
is equipped with a GFI circuit breaker . Al­
ways protect the sockets from water, mois ­
ture and other fluids .
- Never plug the engine preheater into a con­
ventional outlet, regardless of whether it is protected against a short circuit or not .
.&_ WARNING
-
Short circuiting, fire, serious injuries and life­
threatening or lethal electric shock can result
from using unsuitable or damaged sockets and connector cables/extension cords, using
electrical equipment incorrectly, and/or disre­
garding general safety precautions.
- Always plug the extension cord into a 120 V
socket that is properly functioning, ground­
ed, equipped with a GFI circuit breaker and
is protected against water, moisture and
other fluids.
- Never connect the engine preheater to a
conventional socket, even if the socket is
protected by a fuse.
- Always check the fuse on the 120 Volt GFI
socket before connecting the connector ca­
ble to the engine preheater on the vehicle.
- Only use highly durable extension cords that
are class 12 or better and can be properly grounded to a three-prong wall socket with
a GFI circuit breaker . The extension cord
must not be longer than 100 feet (30 me­
ters).
- Never use damaged connector cables, ex­
tension cords or sockets . Always check the
connector cable, extension cord and sockets
for damage before using them. Damaged
parts must be replaced. If damaged, replace
76
the engine preheater connector cable at an
authorized Audi dealer or authorized Audi
service facility .
- Only use the connector cable provided to
connect the vehicle socket to a suitable
power source. Use a suitable extension cord
if necessary .
- Always disconnect the connector cable from
the vehicle socket before starting the en­
gine. Switch off the power supply to the
connector cable and to the extension cord if necessary, or disconnect the cable or exten­
sion cord from the 120 Volt socket equip­
ped with a GFI circuit breaker. Never leave
the connector cable or extension cord con­
nected to a live power source.
- Never make alterations or repairs to the
connector cables or extension cords that
supply power to the engine preheater or to
any components that affect the engine pre­
heater.
- Always protect the connections from water,
moisture and other fluids. Always store the
connector cable and extension cord securely
and in a dry place when they are not being
used, and disconnect them from the power
source before storing .
(D Tips

General information
The first 1,000 miles (1,500 km) and afterwards
The new engine needs to be run-in during the
first 1,000 miles (1,500 km).
For the first 600 mile s (1,000 kilom eter s):
.,. Do not use full throttle.
.,. Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
.,. Avo id high engine speeds .
From 600 to 1,000 mile s (1 ,000 to
1 ,500 kilomete rs ):
.,. Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and aft er bre ak-in pe riod
.,. Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in
N (Neutral) or in gear .
After th e br eak-in p eriod
.,. Do not exceed maximum engine speed under
any circumstances .
.,. Upshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
opage 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break-in process is done depends to a considera­
b le extent on the way the veh icle is driven during
the first 1,000 miles (1,500 kilometers).
CD Note
Extremely high eng ine speeds are automati­
cally reduced. However, these rpm lim its are
programmed for an engine well run-in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
D riv ing
Driving through water on roads
Note the following to avo id vehicle damage when
driv ing th rough water, for example on flooded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not drive faster than walk ing speed .
.&, WARNING ..__
After driv ing through water or mud, the brak­
i ng effect can be reduced d ue to moistu re on
the brake d iscs and bra ke pads. A few careful
brake applications should dry off the brakes.
CD Note
Vehicle components such as the engine,
transmission, suspension o r electrical system
can be severely damaged by d riving throug h
water.
(D Tips
- Determine the depth before dr iving through
water.
- Do not stop the vehicle, d rive in reverse or
switch t he engine off when d riving through
water .
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
ma ke it too deep for yo ur vehicle to drive
through safe ly.
- Avoid dr iv ing th rough salt wate r (cor rosion) .
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, env ironmental impact, and wear
on your engine, brakes and t ires largely depend
on three factors:
- your personal driving style
- operat ing cond itions
- technical limitations
77

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 . ..,.

You must drive your vehicle about 3,000 miles
(5 ,000 kilomet ers) before you can prop erly as ­
sess o il consumption .
This a lso applies to fuel consump tion and engine
output .
(D Note
-Have your vehicle mainta ined properly and
i n accor dance wi th the service re commenda­
tions in yo ur War ranty
& Maintenance book ­
l et. Lack of proper maintenance as well as
i mproper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or remove any component of
the Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shie lds, sw itches, ignition wires,
valves, which a re designed to protect yo ur
vehicle's Em ission Control System and other
i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
• Try to avoid driving short dist ances with a cold
engi ne .
T he eng ine and catalytic converter have to reach
their optimal
operating tempe rature to reduce
fuel consump tion and noxious emissions effec­
tively .
Just after starting, a cold engine in a mid-si ze car
only achieves a fuel economy of 6-8 miles per
ga llon (30-40 l/100 km). A fter about a half a
m ile , fuel economy cl imbs to 12 mpg (20 l/
100 km) . After about
2.5 miles (4 km), the en­
g ine is a t its prope r operating temperature and
fuel economy has reache d a normal level. So you
c a n see t hat you s hou ld avoid sho rt t rips whenev­
er possib le .
The
outside temperature is also cr itical in th is re­
g ar d. Yo ur car c onsumes mo re fuel in the w in ter
than in the s umme r.
