Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat
adjustment, may not be available. The convenience functions will be
available again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged .
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display :
Please start engine, otherwise system will switch off in
3 minutes.
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions,
you have to start the engine .
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers
which require especially large amounts of energy are temporarily
cut back or switched off. Heating systems in particular require a
great deal of energy. If you notice, for example, that the heated
seats* or the heated rear window are not heating, they have been
temporarily cut back or switched off. These systems will be available
again as soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased
slightly . This is normal and not a cause for concern. By increasing
engine idle speed the additional energy required is generated and
the battery is charged.
Driver not ification in the instrument cluster
d isplay
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
'-' Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
engine may be limited. As soon as you start driving again, the
battery will be recharged and the notification will go out.
Driver notification appears and goes out again
If this driver notification appears after the ignition is turned on or
while driving and it goes out again after a while, the battery has
been adequately recharged.
Driver notification appears and does not go out again
If this driver notification appears after the ignition is turned on or
while driving and does not go out again, the battery's state of
charge is not in the optimal range . Starting ability is restricted . Have
the battery checked as soon as possible by an authorized Audi
dealer or qualified workshop. •

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 va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can properly assess oil consumption.
This 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
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emiss ion Contro l
System unless approved by the manufacturer.
• Do not alter or remove any device, such as hea t shields,
switches, ignition wires, valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle
components. •
Fewer short trips
~-----------------
Fu e I consumptio n will always be relat ively high on short
tri ps.
- Try to avo id driving s hor t distan ces wit h a cold engine.
The engine and catalytic converter have to reach their optimal oper­
ating t emper ature
to reduce fuel consumption and noxious emis­
sions effective ly .
Just after starting, a cold engine in a mid-size car only achieves a
fue l economy of 6 -8 miles per gallon (30 -40 1/100 km). After about a
half a mile, fuel economy climbs to 12 mpg (201/100 kml. After about
2.5 miles (4 km), the engine is at its proper operating temperature

and fuel economy has reached a normal level. So you can see that
you sh ould avoid short trips whenever possib le .
The
o ut side t emper atu re is also critical in this regard. Your car
consumes more fuel in the winter than in the summer .•

- Dab at the stain. Start at the outside and work inwards.
- Once the stain is no longer v isible, use a soft dry cloth or
tissue to soak up the moisture.
Do not use lea ther cleaning produc ts on Alcantara®.
You may use a suitable shampoo for removing dust and dirt.
Dust and grit in the pores and seams can scratch and damage the
surface. If the car is left standing in the sun for long periods, the
Alcantara® should be protected against direct sunlight to prevent it
from fading. Slight color variations will develop in normal use and are not an indication of material deterioration.
0 Note
• Never use chemical solvents (e.g. lighter fluid, turpentine),
waxes , shoe polish or similar products on Alcantara ® surfaces.
• To avoid damage, have stubborn stains removed by a commer ­
cial cleaning specialist.
• Do not use brushes, stiff sponges or similarly abrasive cleaning
aids. •
Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution . Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly .
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them .
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.

Engine compartment
Be especially careful when cleaning the engine comport­
ment.
Always switch off the ignition before cleaning the engine => &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the .,_

Fuel supply and filling your fuel tank
Gasoline
Fuel supply Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 337, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 266 .
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance.
F ue l supply and fillin g you r fu el tank
Gasoline most common ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
pump:
• Premium Grade : 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R +M)/2 = (RON +MON)/2
RON = Research Octane Number
MON
= M otor Octane Number .
0 Note
• Do not use any fue l with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline. The use of leaded gasoline w ill
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• Anti-knock index must be 87 AKI or higher .
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.

<£> For the sake of the environment
As soon as the correctly operated nozzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addition, the expansion space in the fuel tank
will be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i] Tips
• Running your engine while refuelling may cause vapors to
escape or even cause fuel to spill out of the tank. This would then
shut off the fuel nozzle before the tank is full.
• Do not refuel your vehicle with the ignition turned on. The fuel
gauge may otherwise not indicate the correct fuel level after refuel ­
ling .
• The fuel filler flap of your vehicle is not locked when you lock the
vehicle from the inside .•
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.

0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult an authorized Audi
dealer to have the cause of your concern properly diagnosed. Keep
in mind that the accurate measurement of oil consumption requires
great care and may take some time. An authorized Audi dealer has
instructions about how to measure oil consumption accurately. •
Checking the engine oil level
Read oil level
Fig. 223 MMI Display;
Oil level indicator
Select: Function button [CARI> Oil level.
- Park your vehicle so that it is horizontally level. Shut
the engine off when it is at operating temperature.
Wait approx. two minutes. Read the oil level in the MMI* Display=> fig. 223. Add
engine oil if the bar of the oil level indicator is near "Min"
=>
page 275
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to a 1/2 quart per 600 miles (0.5
liter per 1000 kml. Consumption may be higher within the first 3000
miles (5000 kml.
[ i] Tips
The oil level indicator in the MMI* Display is only an information
display. If the oil level is too low, a minimum oil warning appears in
the instrument cluster. Add oil
=> page 275. If the hood has been
opened, the current oil level is shown in the instrument cluster the
next time the ignition is switched on. •
