What you should know
The highest priority is given to maintaining start­
ing capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year . Abundant electrical energy is required, but
only a little is generated . It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you w ill no­
tice energy management actively regulating the
d istribution of ene rgy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks , electr ical components are
gradually cut back or switched off . This reduces
energy consumption and maintains starting ca­
pability over a longer pe riod .
Take into consideration that when you unlock
your veh icle, 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, the battery is being dis­
charged .
If starting capability is jeopardized due to energy
consumption, a message appears in the driver in­
formation display .
You have to start the engine to charge the bat ­
tery .
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 en­
ergy is be ing generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
Intelligent technology
To bring the energy balance back into equilibri­
um, consumers which require especially large
amounts of energy are temporar ily cut back or
switched off. Heating systems in part icu lar re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo­
rarily cut back or switched off . These systems w ill
be available again as soon as the energy balance
has been restored.
You w ill also not ice that engine idle speed has
been increased slightly . This is normal and not a
cause for concern. By incr easing eng ine idle
speed the additional energy required is generated
and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops in to the range where it
can limit the ability of the engine to start, this is
shown in the instrument cluster display w ith 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 re­
charged and the notificat ion will go out .
Driver notification appears and goes out
again
If this driver notification appears after the igni­
tion is turned on or while driv ing and it goes out
again after a while, the battery has been ade ­
quately recharged .
Driver notification appears and does not go
out again
If this driver notif ication appears after the ign i­
t ion is turned on or while dr iv ing and does not go
out again, the battery's state of charge is not in
t h e optimal range. Starting ability is restricted .
Have the battery checked as soon as possible by
an authorized Audi dea le r or qualified workshop.

Driving and en vironment
Driving and environment
Break-in period
A new vehicle must be broken in, and the break-in
period shou ld be 1 ,500 miles (2,500 km) . Do not
use full acceleration for the first 600 miles
(1 ,000 km) and do not exceed the maximum en­
gine speed of 6,000 rpm You must also not use
full accelerat ion between 600 and 1,200 miles
(1,000 to 2,000 km) . From 1,200 to 1,500 miles
(2 ,000 to 2,500 km), you can gradually increase
maximum eng ine speed to 8,250 rpm for brief
pe riods.
During the first hours of operation, there is
greater fr iction in the eng ine and the transmis­
sion than later when all the moving pa rts have
b roken in .
The way you drive during the first 1,500 miles
(2 ,500 km) affects engine quality . If you drive at
modera te engine speeds thereafter, part icu larly
when the engine is cold, yo u red uce eng ine wea r
and increase the potential mileage o f the engine.
Do not dr ive at RPMs that a re too
low. Shift down
when the engine is no longe r runni ng "smooth­
ly". Extremely high RPMs are gover ned automati­
cally.
Avoid damaging the
vehicle
W hen 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 .
This is especially true for vehicles with low-slung
chassis (sports chassis) and fully loaded vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
d riving through water, for examp le on flooded
roads:
- The water must no t be any h igher than the bot­
tom of the vehicle body.
142
- Do not drive faster than walk ing speed .
A WARNING
After driv ing through water, mud, s lush, etc .,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by brak ing carefully to restore the full
braking effect.
(D Note
Vehicle components such as the eng ine,
transmission , suspension or e lectrical system
can be severe ly damaged by dr iv ing t hrough
water .
(D Tips
- Check the dept h of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or switch the engine off when driv ing through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to d rive
through safely .
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmen tally sound manner.
.,. Always use lead-free gasoline ~ page 151,
Fuel supply.
.,. Never r un the tank down all the way to empty.
.,. Never put too much mo tor o il in yo ur engi ne
~ page 160, Adding engine oil 'l::r..
.,. Never try to push- or tow-sta rt your vehicle .
The cata lytic converter is an effi cien t "clean -up"
device built in to the exhaust system of the vehi ­
cle. The cata lytic conve rter burns many of the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.

Engine oil
Engine oil specificat ions
The engine oil used must conform to exact speci­
fications .
The service interval display in the instrument
cluster of your vehicle will inform you when it is
time for an oil change . We recommend that you
have your oil changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table.
Audi oil quality standard
Gasoline
VW 502 00 or
engine vw 504 00
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
- Use only a high quality engine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
158
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a high-quality
"synthetic"oil that meets the following speci­
fications.
- ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE 5W-30 or SAE 5W-40.
- For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer
or Audi Customer Relations at
1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all of
its moving ports.
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­
gine and may change significantly over the life of
the engine. Typically, engines with a specified break-in period (see
¢ page 142) consume more
oil during the break-in period than they consume
after oil consumption has stabili zed.
Under normal conditions , the rate of oil con­
sumption depends on the quality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions . Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time until replacement of worn components may
become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be estab­
lished or specified. There is no alternative to reg­
ular and frequent checking of the oil level, see
Note.

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
T he coo ling system is sealed and genera lly re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixtu re of
specially conditioned wate r and the manufactur­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture both
assures the necessary frost protection and pro­
tects metal components in the engine's cooling
system from corrosio n and scaling. It also ra ises
the boiling point of the coolant .
1111-
161

Checking and filling
Do not reduce the concentration of the coo lant in
the summer by adding p lain water.
The propor·
tion of coolant additive must be at least 50%
but not more than 60%
to maintain antifreeze
protection and cooling efficiency .
If the coolant
frost protection is too low, the coolant could
freeze and damage the ve hicle heating and en­
g ine cooling system .
For year-round driving, antifreeze is added at the
factory for temperatures down to:
- - 31 ° F ( -3 5 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended .
& WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
<=> .&. in Working in the engine compart­
ment on page 155.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions . This is especially important if you
live in a region where the winter is extreme­
l y cold. If necessary, increase the proportion
of coolant add itive to 60%.
- When adding coolant addit ive to your cool­
in g system, remember:
- We recommend using only coolant addi­
tive G12++ or G13 for your vehicle. This
coolant additive is available at authorized
Audi dealers. Other types of antifreeze can
signif icant ly reduce corrosion protection.
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Add ing ra­
diator repair fluid may adversely affect the
funct ion and pe rformance of your cooling
system and could result in damage not cov­
ered by you r New Vehicle Lim ited Warranty.
