the battery voltage is too low.•

Intelligent t echnology
---------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors=>
page 245. If a not iceab le
slip is detected at the wheels (e.g. on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
Electronic limited slip differential
In vehicles w ith front wheel drive *, an e lectron ic lim ited slip d ifferen­
tial engages when driving on curves . The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. T his m ini­
m izes sliding on the front wheels and enables precise and neutral dr
iv ing t hrouge curves. The electronic lim ited slip differentia l does
no t engage whe n driving in we t cond it io ns or snow.
& WARNING
• Wh en acc elerating on slipp ery s urface s, such a s on ice or snow,
always be careful when depre ssing the accele rator pedal. Even
with the EDL and the electroni c limited slip differential working,
the dr ive wh eels can spin and reduce you r ability to control your
c ar . -Ri sk of cra sh!
• The increased safet y afforded b y EDL and the electronic l imited
slip differ ential d oes not mean th at you can take safety risks .
Alw ay s adapt your d riving st yle to the road c onditions and traffi c
si tuation.
[ i ] Tips
If a fa ult occurs in the ABS, the EDL is also not funct ioning. This is
ind icated by the ABS warn ing light=>
page 16 . •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is a ccelerating.
General notes
T he Anti-Slip Regu lation System (ASR) is in tegrated in the electronic
stabilization program (ESP) . When the veh icle starts up and acceler­
a tes, the wheels are preven ted from sp inning by adjust ing the engine
power to match the amount of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervent ion.
With the a id o f the ABS sensors=>
page 245, ASR moni tors the speed
of the driven wheels. If the wheels start to spin, engine torque is
reduced automatically unti l the tires find enough grip to lock onto
the road s urface. The system is active across the entire speed range . .,

Intelligent technology
'-------------------------------------------------
vi dual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery .
[I] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 249, "Driver notification in the instrument cluster display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
Th e battery is severe ly 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 prec ise ly these sit uations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or sw itched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remo te key or power seat adjust­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
W ith 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.
Th e warn ing indicates that the system will be turned off automati­
cally after 3 m inutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens most ly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
T o br ing the ene rgy 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 ava ilable again as soon as
the energy ba lance 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
eng ine id le speed the additional energy required is generated and the
battery is charged. •

& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself:
• Wear eye protection .
• To reduce the risk of burns from hot engine oil, let the engine
cool down to the touch .
• When removing the oil drain plug with your fingers , stay as far
away as possible. Always keep your forearm parallel to the ground
to help 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 total amount of oil in your
engine .
• Engine oil is poisonous . Keep it well out of the reach of chil­
dren.
• Continuous contact with used engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water .

Engine cooling system
Coolant
The engin e coolan t p erforms two fun ctions: it ke ep s t he
en gine from overheati ng and i t protects the engine fr om
fr eez in g in th e winte r.
Th e cooling system is sea le d and genera lly requ ires lit tle at tention.
Th e cooling system has been f illed at th e factory w it h a p erm anent
coo lant which does not need to be changed. T he coolant cons ists o f a
mix tur e of wa ter a nd the manufacturer's gly co l-basedcoolan t addi ­
tive
Gl2+ + antifreeze with anticorros ion addit ives (50% for USA
m odels; 60 % fo r C an ad ian models). This mixture both as su re s th e
necessary frost protect ion and protects meta l components in the
eng ine's coolin g sy stem fr om co rrosion and scaling .
It als o ra ises the
boiling point of th e coolant.
Do not re duce the concentration of the coo lant in the summer by
add ing p la in wate r.
The proportion of coolant additive must be at
least 50 % but not more than 60%
to mai ntain antifreeze protection
an d co olin g efficiency . If the co ola nt frost p ro te ct ion i s to o low , the
coo lant co uld freeze and damage the veh icle heating and engine
cooling system.
For year -round drivi ng, antifreeze is added at t he factory for tempe r-
atures down to: .,,

-~_C_ h_e _c_ k_ i_ n ....: g:::e._ a_ n _ d_ f_il _l _in _ g =- --------------------------------------------
The expansion tank in your vehicle is equipped with an electric coolant
level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System ~
page 29 will 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
coo lant loss, the cooling system should be inspected immed iate ly 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.
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.
• Protect your face, hands and arms from escaping fluid and
steam by covering the cap with a large, thick rag.
• Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pressure on the top of
the cap.
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coo lant. Adding radiator repair fluid may adverse ly affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty.•
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS::::::> & in "Working in
the engine compartment" on
page 280.
-Turn off the engine .
- Let the engine cool down.
- Place a thick rag over the coolant expansion tank
=> page 287, fig. 223 and carefully turn the cap counter­
clockwise ::::,
&.
- Add coolant .
- Twist the cap on again
tightly.
Replacement engine coolant must conform to exact specifications
~ page 286, "Coolant". Even in an emergency, if coolant additive
G12 ++, G12+ or G12 is not available, do not use a different additive.
Use plain water instead until you can get the correct additive and can
restore the correct ratio. This should be done as soon as possible .
If you have lost a considerable amount of coolant, then you should
add cold antifreeze and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the ''MAX" mark. Excess coolant will be
forced out through the press ure re lief va lve in the cap when the
eng ine becomes hot .
& WARNING
• The cooling system is under pressure and can get very hot.
Reduce the risk of scalding from hot coolant by following these
steps.
-Turn off the engine and allow it to cool down. _.,

Bulbs
Replacing bulbs
F or your safety, we recommend that you have your autho­
ri zed Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diff icult to rep lace vehicle
ligh t bulbs since in many cases, other parts o f the car must fi rst be
removed before yo u are able to get to the bulb . This applies especially
to the light bu lbs in the front of your car which you can on ly reach
throug h the engi ne compartment .
Sheet meta l and bu lb holders can have sharp edges that can ca use
ser ious cuts, parts must be co rrectly t aken ap art and the n properly
put back together to he lp prevent breakage of parts and long term
d am age fro m water t hat c an enter housings that have no t been p rop­
erly resea led.
For your safety, we recommend that you have you r authorized Audi
dealer replace any bulbs fo r you, since yo ur dealer has t he p roper
too ls, the correct bu lbs and the expertise.
Gas discharge lamp s (Xenon light s)* :
Due to the high electr ica l voltage , have the bulbs replaced by a qual­
ified technicia n. Hea dlights w ith Xenon light are ident ified by the
high voltage sticker .
& WARNING
Changing Xenon lamps w ithout the necessary equipment can
cause serious personal injury.
• Bulbs are pressur ized and can explode when being changed.
Potential risk of injury !
• On vehicles equipped with gas discharge bulbs (Xenon light )*
lif e-threatening injurie s can re sult from improper handling of the
high- voltage port ions of such lamps ! .,_
