2011 AUDI A3 starting

Driving and environment
------------------------------------------------'
you start the engine and avoid running at high RPMs while the engine
is still warming up.
0 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
overheat ing or other damage to the vehicle or other property.•
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 authorized Audi dealer
helps to ensure that it runs properly and economically. The condition
of your vehicle not on ly 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 engine to reach its
lowest value after a certain mi leage has been driven.
You must drive you r vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
Thi s also applies to fuel consumption and engine output.
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle will
impa ir the function of the emission control system and could lead to
damage.
Controls and equip­ ment Safety first Vehicle operation
•
Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, switches,
ignition w ires, va lves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components.
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper­
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively .
• Just after starting, a cold eng ine in a mid-size car burns the fuel at
a poor rate of 6-8 miles per gallon (30-40 l/l00km). Half a mile down
the road, the mileage improves to 12 MPG (20 l/100 km). It will take
the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at an
economic mileage . This explains why taking the car for sho rt trips is a
rather wasteful convenience .
• Th e
outside temperature is also critical in this regard . Your car
consumes more fuel in the winter than in the summer.

Parking on a slope
Do not park with a trailer on a slope. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until wheel
blocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
- Place an automatic transmission in
P, respectively a
manual transmission in first or reverse gear.
When restarting after parking:
- Start the engine .
- Shift transmission into gear .
- Release the parking brake and slowly pull out and away from the wheel blocks .
- Stop and have someone retrieve the wheel blocks.
[I] Tips
If you move the selector lever of the automatic transmiss ion to P
before applying the parking brake and before blocking the wheels,
you may have to use more force later to move the leve r out of the
P
position. •

Some states in the USA require permits to purchase diesel fuel. Check
with your State Motor Vehicle Department.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before traveling to other countries .
Winter operation
At temperatures below 20° F (- 7° C), Diesel fue l No. 2 loses its fluidity
due to wax separation, which may clog the fuel filter or tank filter and
keep the engine from running.
T o help the filter from being clogged by wax, the fuel fi lter in your
vehicle is automatically preheated. Preheating the fuel filter makes
operat ion of your vehicle possib le with Diesel fuel No. 2 down to -
10° F (-24° C).
If you expect temperatures below 5° F (-15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is suffic iently w interized for the
prevailing and expected temperatures.
If not winte rized or insuffic iently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during the
warm-up period in winter.
It is also normal when whitish -blue smoke
comes out of the tailpipe after start ing and during warm-up. The
amount of smoke depends on the outside temperature.
Do not let your diese l engine id le unnecessari ly after a cold start.
Driving off slowly will shorten the warm-up period.
& WARNING
• Never use "starting assist fluids." They may be potentially
explosive or cause a "run-away" engine condition. This could
result in serious engine damage and personal injury.
• Never use fuel line anti-freeze offered for gasoline engines.
Safety first
0 Note
• Your diesel engine has been specifically designed to operate only
on Ultra Low Sulfur Diesel fue l. Therefore, never use home heating oil
or regu lar gaso line. The properties of these fuels may cause serious
damage to the fuel injection system and to the engine. Using these
fue ls can cause expens ive eng ine repairs and will also adversely affect
your New Vehicle Limited Warranty.
• If diesel fuel should get on any rubber hose, it must be wiped off
immediately. Then wash the contaminated hose portion with soap
and warm water. Do not allow diesel fuel to rema in on connecting
hoses. They may deve lop leaks and cause serious damage. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fue l filler flap.
If the power locking system should fa il, you can still open the flap
manually - for detai led instructions see=>
page 224.
You ca n find the fuel tank capacity of your vehicle in Technical Data
=> page 296 .
The label on the inside of the fue l filler flap tells you the correct fuel
for your veh icle. For more information about fuel specifications, see
=> page 219.
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protect ing the environment,
please follow this refueling procedure carefully. .,,
