to the other drive wheel or wheels (all-whee l drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 16. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test. You can activate a deactivated ASR if required
by pressing the=>
page 188, fig. 158 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 188, fig . 158. With the ASR deactivated,
the ESP check light comes on, see=>
page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains

The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire.
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields . During driving, the substance used for undercoating
could overheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel will already
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level~
page 230.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement.
• To assure efficient operation of the Emission Control System :
- 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 impair the function of the emission control system
and could lead to damage.
Controls and equip­ ment Safety first Vehicle operation
Driving and environment
<£' 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
operating states . This depends on the sulfur content of the fuel
being used . Using a different brand of fuel may help, or filling the
tank with lead-free super grade gasoline. •
Applies to veh ic les : with diesel particulate filter
Diesel particu ate filter
The diesel particulate filter filters nearly all of the soot particles out
of the exhaust. The filter cleans itself automatically under normal
driving conditions. If the filter cannot clean itself (for example,
because you are only driving short distances), the filter becomes
clogged with soot and the symbol for the diesel particulate filter
illuminates ~
page 32.
& 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.
[ i] Tips
• When the diesel particulate filter becomes saturated, the engine
speed increases to approximately 1,500 rpm while the vehicle is in
motion to initiate the cleaning of the diesel particulate filter auto­
matically without the warning lamp lighting up. If the warning lamp
still appears, you should drive to a qualified workshop. •

long waits on red. Turning the engine off for just 30 -40 seconds
saves more f ue l than i s bu rned star ting the engine again.
It takes a long time for the engine to warm up fully when it is
running at idle. However , wear and noxious em issions are especial ly
h ig h w hen the eng ine is warming up. So y ou should dr ive away as
soon as you start the engine and avoid running at high RPMs whi le
the eng ine is still warming up.
0 Note
Do not leave en gine idling unattended after starting. If warn ing
lights should come on to indicate improper operation, they would
go unheeded . Extended idling also produces heat, wh ich cou ld
result in overheating 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 regu lar intervals.
By having your vehicle regu lar ly serviced by an authorized Audi
dea ler he lps to ensure that it runs properly and econo mically . The
condition of your vehicle not only affects its safety and abi lity to
hold i ts va lue, it a lso affects fuel consumpt ion .
Che ck yo ur oil ea ch t ime you fill your t ank.
T he amount of oil used is related to engine load and speed.
It is nor mal for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can proper ly assess oil consumption .

Fewer short trips
Fuel consump tion will always be relatively hi gh on shor t
trips.
- Try to avo id driving short dista nces wi th a cold en gine.
The engine and cata lytic c onverter have to reach their optima l oper ­
ating temperature to reduce fuel consumption and noxious emis ­
sions effective ly .
• Just after starting, a cold engine in a mid-size car burns the fuel
at a poor rate of 6 -8 miles per gallon (30 -40 11100km). Half a mi le
down the road, the mileage improves to 12 MPG (20 1/100 km). It wi ll
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 a n
economic mileage . This exp lains why taking the car for short trips is
a ra ther waste ful convenience .
• The outs ide temperat ure is also critical in this regard. Your car
consumes more fuel in the winter than in the summer .•

Cleaning and protection -
----------------=-----=------
•
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.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your authorized Audi dealer.
• Always read and heed all WARNINGS and other information
=:, page 204. •
Engine compartment
Be especially careful when cleaning the engine compart­
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
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
3l, or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well . It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information

labeled ask the station operator what fuel is being dispensed before
filling up your vehic le .
Service stations offering diesel fuel are generally located on truck
routes or major highways. Directories of diesel fuel stations are
usually available at diese l fuel stations.
Some states in the USA require permits to purchase diesel fuel.
Check with your State Motor Vehicle Department.
Diesel fuel may not be available outside the USA and Canada . Be
su re to check before traveling to other countries .
Winte r ope ra ti on
At temperatures be low 20° F (- 7° Cl, Diesel fuel No. 2 loses its fluidity
due to wax separation, which may c log the fuel filter or tank filter
and keep the engine from running.
To he lp the filter from being clogged by wax, the fue l filter in your
vehic le is automatically preheated. Preheating the fuel fi lter makes
operation of your vehicle poss ible with Diese l fue l No. 2 down to -
10° F (- 24° Cl.
If you expect tempe ratures below 5° F ( -15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is sufficiently winterized for the prevai ling and expected temperatures .
If not winterized or insufficiently 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 per iod in winter. It is also normal when whitish -blue
smoke comes out of the tailpipe after starting and dur ing warm-up.
The amount of smoke depends on the outside temperature .
Do not let your diese l eng ine idle unnecessarily after a cold start.
Driving off slowly will shorten the warm -up period.

Engine cooling system
Coolant
The engine coolant perf orms two functions: it keeps the
engine from overheating an d it protects the engine from
freezing in the winter.
The cooling system is sealed and general ly requires litt le attention.
The coo ling system has been fi lled at the factory with a permanent
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the manufacturer's glycol -basedcoolant
additive G12+ + antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian mode ls) . This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling. It also raises
the boil ing point o f the coolant.
Do not reduce the concentration of the coo lant in the summer by
adding pla in water. The proporti on of coolant additive mu st b e at
l e as t 50 % but not more than 60 % to maintain antifreeze protection
and cooling efficiency . If the coolant frost protect ion is too low, the
coo lant could freeze and damage the vehicle heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper ­
atures down to :
• -31 °F ( -35 °C) USA
• -40 °F ( -40 °C) Canada .
You can mix the G12 ++ coolan t additive with other additives G12 + or
G12. Always check with your authorized Audi dealer.
& WARNING
Bef ore you che ck anything in the engine compartment , alwa ys
read and heed all WARNING S
~ & in "Working in the engine
c ompartment " on
page 22 4.

Checking and filling -
---------------------=----"=---------
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
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. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and cou ld result
in damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 169 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 224.
Turn off the ignition .
Read the engine coolant level from the coolant expan­
sion tank==> fig. 169. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 225.
To obtain an accurate reading, the engine must be switched off .
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..
