Energy management
Starting ability is optimized
E nergy ma nagement co ntr ols the distribution of elec
trical energy and thus optimizes the availa bility of elec
trical energy for s tarting the engine.
If a vehicle with a convention al ene rgy sys tem is not driven fo r a lo ng
pe riod of time, the battery is d ischarged by idling cu rr ent consumers
(e.g. immo bilizer) . In ce rtain c ircumstances it can result i n there

Intelligent technology
'-------------------------------------------------
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust
me nt, may not be available. The convenience functions will be avail
able 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 start ing 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 equilibr ium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heat ing 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 norma l and not a cause for concern. By increasing
engine idle speed the additional energy required is generated and the
battery is charged.
Driver notification in the instrument
cluster display
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:
i...-3 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
w ill be recharged and the notification will go out.
Driver notification appears and goes out again
If th is driver notification appears after the ignition is turned on or
whi le 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 o r
wh ile 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. •

Ap plies to veh icles : w it h gasoline eng ine
Catalyt·c converter
It is very important tha t your emission con trol system
(catalytic c onverte r) is f unctioning properly to ensure
that your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline~ page 291, "Gasoline" .
- Never ru n the tan k down a ll the way to empty .
- Nev er put to o mu ch mot or oil in y our engin e~
pag e 306,
"Add ing engin e oil~" -
- Neve r try to push -or tow-start yo ur vehicle .
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the ve hicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere. The exclusive
use of unleaded fuel is critically important for the life of
t he c atal ytic converte r and proper f unct ion in g of t he engi ne.
& WARNING
• Do not park or operate the vehicle in areas where the hot
e x haust system may come in contact with dry grass , brush , fuel
s pill or other material whi ch can cau se a fire.
• Do not apply additional undercoating or rustp roofing on or
near the exhau st manifold, exhaust pipe s, catalytic converter or
heat shields. During driving , the substance used for undercoating
c ould overheat and cau se a fire .
0 Note
• Be aware th at just one tank fi lling wit h le aded fu el w ill alre ady
ser iously degrade the performance of the catalytic co nverter.
• Do not excee d the correct engine oil leve l~
page 306.
• Do not drive unti l the f uel tank becomes complete ly empty . The
eng ine could misfire. Unbu rned fuel could also ge t into the exha ust
system and th is could cause the catalytic converter to overheat.
• Do not tu rn off the igni tion whi le the veh icle is moving .
• Do not contin ue to operate your vehicle under these conditions, as
o therwise fuel can reach the cata lytic converter . This could result in
overheating of the converte r, requiring its rep lacement.
• To assu re eff icient operat ion of the Emission Co ntrol System:
- Have yo ur vehicle main taine d pr operly and in a ccordan ce wi th
the service recommendations in your Warranty
& Maintenance
booklet .
- Lack of p roper maintenance as well as improper use of the
veh icle w ill imp air the f unction of the emiss io n con trol syste m and
could lead to damage. ..

• Driving and environment
------------------------------------------------'
ffi For the sake of the environment
Even when the Emission Control System is operating properly, the
exhaust gas can have a sulfur-like exhaust gas smell under some
operat ing states. This depends on the sulfur content of the fue l being
used. Using a different brand of fuel may help, or filling the tank with
lead-free supe r grade gasoline. •
Applies to vehicles: with d iesel engine
Diesel particulate filter
The diesel particulate filter filters nearly all of the soot particles out
of the exhaust. The filter cleans itself automatica lly under norma l
driving conditions. If the filter cannot clean itself (for example,
because you are only driving short distances), the fi lter becomes
clogged with soot and the symbol for the diesel particulate filter
illuminates ~
page 40.
& WARNING
• Do not park your vehicle over flammable materials such as
grass or leaves because the high temperature of the diesel partic
ulate filter could start a fire.
• Do not apply an underbody protectant in the exhaust system
area or a fire could start. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps, etc.,
make certain that low-lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
Thi s is espec ially true for vehicles with low-slung chassis (sports
chassis)" and fully loaded vehicles. •
Controls and equip

Operate your vehicle economically
and minimize pollution
General
Your personal
style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal dr iv ing style
• operating conditions
• technical limitations
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 he lp the environment
and your pocketbook.
(I) Tips
The consumption est imates 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 accelerating.
-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are accelerating . If you antici
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible - for
example when you see that the next traffic light is red. •
Vehicle care Do-it-yourself service Technical data
Page 270 of 392

Driving and environment
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption , exhaust emiss ions and eng ine no ise increase
disproportionately at high speeds . If you drive at approximately three
quarte rs of top speed, fuel consumption will be reduced by one ha lf.
Never drive faster than the posted speed limit and weather condi
tions permit. •
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 engine run at
idle .
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at railroad crossings , or at traffic lights that have long
waits on red. Turning the engine off for just 30-40 seconds saves
more fuel than is burned starting the engine aga in.
It takes a long time for the engine to warm up fully when it is running
at idle . However, wea r and noxious emiss ions 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 .
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
ove rheating 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 serv iced by an authorized Aud i 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 a lso 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 norma l for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been d riven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) befo re you can properly assess oi l consumption.
This also app lies to fuel consumption and engine output .
0 Note
• Have your veh icle ma inta ined properly and in accordance w ith the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as im proper 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 Emission Control
System un less approved by the manufacturer. ._
Page 271 of 392

Driving and environment
------------------------------------------------'
• Do not alter or remove any device, such as heat shields, switches,
ign ition w ires, valves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components. •
Fewer short trips
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 optima l oper
ating temperature
to reduce fuel consumption and noxious emis
sions effectively.
Just after starting, a cold engine in a mid-size car only achieves a fuel economy of 6-8 miles per gallon (30-40 l/l00km). After about a half
a mile, fuel economy climbs to 12 mpg (20 l/100 km) . After about
2.5 mi les (4 km), the engine is at its proper operating temperature
and fue l economy has reached a normal level. So you can see that you
should avoid short trips whenever possible.
Th e
outside temperature is also critical in this regard. Your car
consumes more fuel in the winter than in the summer. •
