A cold engine may sound loud after it has been started . This is due to
t he hydra ulic valves building up o il pressure . This is norma l an d is not
a need for concern .
If the engine does not start immediately, stop trying after 10 seconds
and then try to rest art the engi ne about 30 seco nds la ter.
Glow plug system*
Diesel engines are eq uipped with a glow p lug system whose
preheating t ime is controlled
by the coo lant and outs ide tempera­
ture. Sta rt the engi ne
immediat ely after the glow pl ug ind icator lig ht
switches off.
Th e g low pl ug indica tor light w ill on ly ill uminate fo r approximately 1
second when the engine is warm or the outside temperature is higher
t han 46 ° F (8 °C). That means you can sta rt the eng ine
immediately .
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon mono xide, a color­
le ss and odorless gas. Carbon monoxide can be fatal if inhaled .
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of person al injury or
theft.
0 Note
• Avoid high e ng ine speeds, fast a cce le ration or heavy eng ine loads
w hile the engine is still co ld. This co uld damage the engine .
• The eng ine ca nnot be sta rted by p ush ing or tow ing the veh icle.
'ii? For the sake of the environment
T o avoid unnecessa ry engine w ea r and to reduce exhaust em iss ions,
do not let your vehicle stand and warm up . Be ready to drive off imme ­
diately after sta rting yo ur vehicle . M aintain mode rate speed u ntil the
eng ine is complete ly warm . Remember, the engine performs best at
operat ing temper ature. •
Stopping the engine
- Tur n the ign it ion key to position @ ==> page 125, fig. 12 2.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop .
• The brake booster and servotronic only work when the engine
i s running . With the ignition turned off, you have to apply more
force when steering or b raking. Since you cannot stee r and stop
normally, this can lead to accidents and serious injuries.
• The radi ator fan can continue to run for up to 10 minute s even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats up because of intense sunlight or heat build-up in the engine
compartment. ..,,

& WA RNING (conti nu ed )
• Plea se be aware th at in ESP offroad mode , particularly on a
s mooth and slippery road, the wheels may have an incr eased
tendency to spin and the vehicle may break awa y -danger of skid ­
ding!
• Stabilit y is limited in the ESP offroad mode. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differe ntia l lock (EDL) helps the ca r to sta rt moving,
acce lerate and climb a gradient on surfaces provi ding poor or almost
no grip. W ithout ED L, th is would be d iff ic ul t, if not impossible .
How the system works
The EDL operates automatically . It mo nitors the rotational speed of
w heels wi th the help of the ABS sensors ==>
page 256 . If a not iceab le
slip is detected at the wheels (e .g . o n slippery g round on one side),
the spin ning whee ls are braked and power is transferred to the other
wheels. This is done up to a speed of about 60 mph ( 100 km/h) .
Noises from the brake system signa l that wheel spin is being
cont rolled.
Driv ing off
W hen d rivi ng off, always be sure to keep road conditions in mind as
you acce lerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of th rottle until t he car starts to move .
Overheating of brakes
To prevent the disc b rake of the bra ked wheel from overhea ting if
subjected to excessive loads on this whee l, t he EDL cuts out tempo ­
ra rily. The vehicle rema ins operat iona l and behaves in the same way
as a veh icle without EDL. As soon as the brake has coo
led down, EDL sw itches on again auto­
m atically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accele rator pedal. Even
with the EDL working , the drive wheels c an 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 d riv ing style to the road
c ondition s and traffic situation.
[ i ] Tips
If a fa ult occurs in the A BS, the ED L is also no t fu nct io ni ng. This is
ind icated by the ABS warn ing light==>
page 19. •
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tion System preven ts the drive n
w heels from spinning when the car is acc ele rating .
General notes
The Anti-S lip Reg ulation Sys tem (ASR) is in tegr ated in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
a tes, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amoun t of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. witho ut the driver 's intervent ion.
With the aid o f th e ABS sensors ==>
page 256, ASR moni to rs the speed
of the driven wheels. If the whee ls start to spin, engine torque is
reduced automatically unt il the tires find enough grip to lock onto
the road s urface. The system is active ac ross the en tire speed range .

'-------------------------------------------------
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. •

Driving and environment
New brake pads
Remember that new brake pads do not have a f ull braki ng
e ff e ct during the first 250 miles (400 kilometers) after they
are i nsta lle d.
New bra ke pads have to be "b urnished in" before they have opt ima l
grab=> &.
Dur ing the break -in period, you sho uld avoid putting severe loads on
the brakes. Severe loads incl ude, for example, sudden hard braki ng,
in particu lar at very high s peeds or, for examp le, on mountai n passes.
& WARNING
New brake pads don 't have the be st stopping power and must be
" broken -in " during the initial 100 to 150 miles (150 to 200 kilo­
meters ) of normal cit y driving. You can compensate for thi s by
pressing th e brak e pedal more firmly. This also applies lat er wh en
new pad s are installed. n

Catalytic converter
--
I t is very important th at your emission control system
(ca talytic co n verter) i s func tioning properly to e nsure
that you r vehicle is running in an environmentally sou nd
manner.
- Always us e lead-fr ee gasoli ne ~ page 287, "Gaso line" .
- Never run the tan k down a ll the way to empty.
- Never put too m uch motor oil in your engine~

•
-Nev er try to p ush- or tow-sta rt yo ur veh icle.
The catalytic converter is an efficient "clean- up" device b uilt into the
exha ust sys te m of the ve hicle. The cat alytic converte r burns many of
t he polluta nts in the exhaust gas before they are released into the
atmosphe re.
Th e e xcl usive use of unleaded fuel is cr itic ally important for the life of
the catalytic converte r and proper f unction ing 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 conve rter or
heat shields. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank fi lling wit h leaded fu el wi ll alrea dy

Winter operation
At t empe ratures below 20° F (- 7° C), Die sel fue l No . 2 l oses its flu idity
due to wax separation, wh ich may clog the fuel filter or tank fi lter and
keep the engine from running .
T o help t he filte r from be ing clogged by wax, the fue l fi lter in your
vehicle is automatically preheated. Preheat ing the fuel f ilter makes
operat io n of yo ur vehicle possib le with Die sel fuel No. 2 dow n to -
10° F (-24° C).
If you expect temperat ures below 5° F (-1S° C) ask yo ur fuel dealer
whether their Diesel fuel No . 2 is suffic iently w interized for the
prevailing and expected temperat ures.
If not winterized or insuff ic ie ntly w inte riz ed Diese l fuel has already
thickened to the extent that the engine w ill not start, warm the
vehicle up by leaving i t in a heated garage.
It is normal that the eng ine noise level (dieseling) is louder during the
warm-up period in winte r. It is also normal when whitish -blue smoke
comes out of t he tailpipe afte r start ing and du ring warm-up. The
amount of smoke depends on the outside temperature .

Engine cooling system
Coolant
The e ngine co o la nt per form s two functio ns: it keeps the
engine from ove rh eati ng and it protects t he engine from
free zing in the winter .
The cooling system is sealed an d genera lly req uir es little attention. The cooling system has been f
illed at the factory wit h a permanent
c oo lant whi ch does no t need to be c hanged . Th e coolan t cons ists o f a
mixt ure of water and the manufacturer's glycol-basedcoolant addi ­
tive G12+ + antifreeze with anticorrosion ad dit ives (50% for USA
mode ls; 60% for Ca nadian models) . This mixture both ass ures the
necessary frost protection and protects meta l components in the
eng ine's cooling system from co rrosion and scaling. It also raise s the
boiling point of the coo lant .
Do not re du ce the co ncent ration of the coo lant in the summer by
add ing p la in water .
The proportion of coolant add itive must be at
least 50% but not more than 60%
to mai ntain an tifreeze pro tection
and coo ling efficiency . If the coolant frost p rotect io n i s too low, the
coo lant co uld freeze an d damage t he veh icle heating and engine
