CD Note
- Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en-
gine load.
- The front spoiler also helps to distribute
cooling air correctly wh ile driving. If the
spo iler is damaged, the cooling effect will
be impai red and the risk of the engine over­
heating will increase. See an authorized
A udi dealer or authori zed Aud i Service Fa­
cility for assistance .
Tachometer
The tachometer displays the engine speed in rev ­
olutions per minute
(RPM).
You shou ld shift to the next lowest gear when
the eng ine speed is be low 1,500 RPM. The beg in­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperature.
Before reaching this zone, you should sh ift into
the next highest gear, select the D selector lever position, or remove your foot from the accelera­
tor pedal.
CD Note
The needle in the tachometer @
Q page 8,
fig. 3 may only be in the red zone of the
gauge for a short t ime or the engine could be
damaged. The location where the red zone
begins va ries depend ing on the eng ine.
@) For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.
Fuel level
The fuel leve l ind icator only ope rates when the
i gnit io n is switched on. The
tD Qpage 15
turns on if the reserve quant ity of fuel is reac hed.

(D Note
Neve r dr ive until the tank is comp lete ly emp­
ty. The irregu la r supply of fuel that res ults
from that can cause engine misfires . Uncom­
busted fuel w ill then enter the exhaust sys­
tem. This can cause overheat ing and damage
to the catalyt ic converter.
Time/date display
You can switch between the quartz clock or the GPS controlled clock* depend ing on the vehicle
equipment. For mo re information, refe r to you r
MM I Operating Manual.
Outside temperature display
T he instrument cluster display shows the outside
temperature. At temperatures be low 42 °F ( +S
°C), a snowflake symbo l appears in front of the
temperature display.
If your vehicle is stationary or if you a re driving at
very low speeds, the temperature displayed may be slight ly higher than the actual temperature
o utside due to the heat radiating from the en ­
gine.
A WARNING
.-
Do not assume the roads are free of ice based
on the outside temperature d isplay. Be aware
that there may be ice on roads even when the
outside tempe rature is a round 42 °F (+5 °C)
a nd that i ce can increase t he risk of a cc idents.

General information
Breaking in
A new vehicle must be broken in, and the break­ in distance should be 1,000 miles (1,500 km).
For the first 600 miles (1,000 km), do not drive
at speeds that are more than 2/3 of the maxi­
mum permitted RPM, avoid full acceleration and
do not tow a trailer. You may gradually start in­
creasing the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
Do not drive at too
low of an engine speed (rpm).
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
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.
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 reduce the risk of vehicle
damage when driving through 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 walking speed.
58
A WARNING ,_
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes.
([) Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style . With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at
the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating .
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible , let your vehicle coast with a gear
engaged, for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel
...

consumption to zero (fuel shut-off during decel­
eration).
Shift efficiently
An effective way to save fuel is to upshift earlier .
Staying in a gear too long uses fuel unnecessari­
ly. Press down on the accelerator pedal slowly
and avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopping the engine, for ex­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engine for
30-40 seconds already saves more fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to warm the en­
gine up to operating temperature . Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check the
oil level when refueling. The oil
consumption
depends largely on the engine load
and speed . It is normal for the oil consumption
of a new engine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approximately 3,000 miles (5,000 km) have been
driven.
Driving
Fewer short trips
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 mpg
(30-40 l/100 km). After about a half a mile, fuel
economy climbs to 12 mpg (20 l/100 km). After
about 2.5 mi
(4 km), the engine is at its proper
operating temperature and fuel economy has
reached a normal level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.
@ 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.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty & Maintenance book­
let. Lack of proper maintenance as well as
improper 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 unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components .

All wheel drive (quattro)
A ppl ies to: ve hicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered.
General info rmation
I n all wheel drive, t he driving power is divided be­
tween all four wheels . This happens automatical­
ly depending on your driving behavior as well as
the current road conditions. Also see
¢ page 92.
The a ll wheel d rive concept is designed for h igh
engine powe r. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics both under norma l driving conditions and on
snow and ice. Always read and fo llow safety pre­
cautions ¢.&. .
Winter t ires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inter con­
ditions. However, we recommend using winter or
all season tires on
all four whee ls in the winter,
because this will improve the
broking effect.
Snow cha in s
If there are snow chain laws, snow chains must
a lso be used on vehicles with a ll wheel drive
¢ page 186, Snow chains.
Replacing t ires
F or vehicles w ith all wheel dr ive, only wheels w ith
the same ro lling circumference shou ld be used .
Avoid using tires with different tread depths
¢ page 178, New tires or wheels .
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci­
dent.
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be­
cause this increases the risk of an accident .
Intellig ent Technology
- Note that on wet streets, the front wheels
can "hydrop lane" if dr iv ing at speeds that
are too high . Un like front wheel drive
veh icles, the engine does not rev higher sud­
denly when the vehicle begins hydroplan ing .
For this reason, adapt yo ur speed to the
road conditions to red uce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is not driven for a long time , the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certa in circumstances, there
could may not be enough energy to start the en ­
gine.
Yo ur vehicle is equipped with an intel ligent ener ­
gy management system for distributing electrici­
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life .
The energy management system Is made up of
battery diagnosis , idling current manag em en t,
and dynamic energy manag ement .
Battery diagn osis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery a re deter­
mined based on this.
Idling current management
The idling current management decreases the energy used while parked. With the engine
switched off, it manages the energy dis tribution
to the d ifferent e lectr ica l components. Data from
the battery d iagnosis is taken into account for
t hi s.

e ngi ne oil from A udi Gen uin e P art s
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 .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set fo rth in the Aud i Owner's
Manual a nd Warranty & Mai ntenan ce booklet.
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil q ual ity
standard specified for your vehicle's engine. Using any other oil can cause serious engine
damage .
- Do not mix any l ubricants or othe r addi tives
into the engine oil. Doing so can cause en­
gine damage.
(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
"synthet ic"oil that meets the following speci­
fications.
- ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE SW-30 or SAE SW-40.
- For more information about engine oi l that
has been approved for your vehicle, please

Ch eck ing and Filling
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and
cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
ing of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly over the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
q page 58) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l !I
in the instrument cluster lights up, you sho uld
check the o il level as soon as possible
q page 164. Top off the o il at your earlies t con­
venience.
A WARNING ~
Before you check anything in the engine com-
partment, always read and heed all WARN­
INGS
q .&. in Working in the engine comport­
ment on page 159.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the eng ine. ..,.

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
i t. Instead , check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
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 instruc­
tions about how to measure oil consump­
tion accurately .

A WARNING
- When adding engine oil, do not let oil drip
onto hot engine components. This increases
the risk of a fire.
- You must seal the cap on the oil filler open­
ing correctly so that oil does not leak out
onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
-A lways clean sk in thoroughly if it comes into
contact with engine oil.

increases the risk of catalytic converter and/
or engine damage. Do not start the engine. Contact an authorized Audi dealer or au­
thorized Audi Service Facility to have excess
engine oil extracted if necessary.
- Do not mix any additional lubricants into
the engine o il. Damage caused by such addi­
tives is not covered by the warranty.
@ For the sake of the environment
-Engine o il should never enter the sewer sys­
tem or come into contact with the ground under any circumstances.
- Pay attention to legal requirements when
dispos ing of empty oil containers.
@ Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
fi rst 3,000 miles (5,000 km). The engine o il
level must be checked regularly.
It would be
best to che ck each t ime you refue l yo ur vehi­
cle and before long dr ives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion.
B efore you check a nyth ing in the eng ine compart­
ment,
alw ay s read and heed all WARNINGS ~ .&.
in Working in the engine compartment on
page 159.
The engine oil must be changed according to the
inte rvals spec ified in you r Warranty
& Mainte­
nance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d uring normal vehicle use.
Unde r some ci rcumstances the eng ine o il should
be changed more frequently. Change oil mo re of ­
ten if yo u drive mos tly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop -and -go traffic condit ions, or have your vehi­
cle where temperat ures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent add itives in the oi l will make fresh oil
l ook dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Beca use of the problem o f proper disposal, along
with the specia l too ls and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authorized
Audi dealer or
a qual ified service stat ion.
If you choo se to change you r oil yourself , please
note the following important info rmation:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
-
- To reduce the r is k of burns from hot engine
oil, let the engine coo l down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possib le. Always
keep your forearm parallel to the gro und to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amou nt of oil in you r engine.
- Engine oil is poisonous. Keep it well out of
the reach of childre n.
- Continuous contact with used engine o il is
