Warning light in the instrument cluster
display
If the . warning light in the instrument cluster
display flashes, this can mean one of two things:
either the coolant
temperature is too high, or the
coolant
level is too low~ page 26.
If the needle is well in the upper area of the
gauge, the coolant temperature is too high.
Stop
the vehicle, switch the engine off, and allow it
to cool. If the warning light comes on again after
driving a short distance, contact an authorized
Audi dealer or other qualified workshop .
_& WARNING
- Always observe the warning in~ page 217,
before opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the engine cool off
first so that you cannot hear or see any
steam or engine coo lant.
CD Note
- Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At high outside temper­
atures or high engine load, the engine could
overheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the vehi­
cle is moving. If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
iz ed Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes) .
If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates max imum permis­
sible engine RPM after the break-in period . Be­
fore reaching this area, move the selector lever
Instruments and indicator lights
to posit ion D/S or ease your foot off the accelera­
tor pedal.
CD Note
The tachometer need le@ ~ page 8, fig. 3
shou ld only briefly be in the red zone: you
could damage your engine! The beginning of
the red zone varies depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Instruments and indicator lights
The number of keys programmed to the vehicle is
also displayed. The display
L2 3/3 in dicates that
three keys have been programmed. This a llows
you to make sure you have received all of the keys
when you purchase a used vehicle.
For examp le, if you on ly receive two keys, you
should take those keys to your authorized Audi
dealer to have the missing key deactivated so it
cannot be used. You should also report the miss­
ing key to your insurance company .
Calling up the driver information
A yellow or red symbol appears in the instrument
cluster display, usually with a driver message.
The driver message display disappears after about 5 seconds. The dr iver message can be dis­
played again by briefly pressing the

-Do not ride the brakes or press the brake
peda l too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the b rake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always ho ld it in
place wi th the brake pedal o r parking brake.
- Never hold the veh icle on an incl ine with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicato r lamp
mJ illum inates
and a driver message appears ¢
page 98
when the clutch is overloaded.
- If the engine must remain running, neve r
have any driving pos ition engaged when
checking under the hood. Make sure these­
lector lever has secure ly engaged and is
locked in P with the parking brake set
¢ page 217. Otherw ise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- When stopping on an incline, do not try to
ho ld the vehicle in place by press ing the ac­
ce lerator pedal while a driv ing gear is se­
l ected. T his can cause the t ransmission to
ove rheat and can damage it. Activate the
parking b rake or press the b rake peda l to
prevent the vehicle from ro lling.
- Al low ing the ve hicl e to ro ll when the eng ine

l ubricated under those ci rcumstances.
(D Tips
F or safety reasons, the parking b rake is re­
leased au tomatically only when the dr iver's
safety belt is engaged in the buckle.
D riv ing
Hill descent control
The hill descent control system assists the driver
when driving down declines .
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
T he transmission automat ically selects a gear
that is su itable for the incline . Hill descent con­
t ro l tries to maintain t he speed ach ieved at the
t ime of b raking, w ith in phys ica l and te chnical
l imita tions.
It may still be necessary to adjust the
speed with the brakes.
Hill descent cont rol switches off once the decline
levels out or you press the acce lerator pedal.
When the speed is set in the cru ise control sys­
tem ¢
page 92, hill descent control is also acti­
vated.
,&. WARNING
H ill descent cont rol cannot over come physical
limitat ions, so it may not be able to ma intain
a constant speed under all conditions. A lways
be ready to app ly the brakes.

Intelligent Technology
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) reinfor­
ces driver safety . It reduces the risk of slipping
and improves driving stability. ESC detects crit i­
cal s ituations such as the vehicle oversteering
and understeering or the wheels sp inning. The
veh icle is stab ilized by applying the brakes or re­
ducing engine torque . Once t he ESC is active, the
indicator light
Ji) blinks in t he instrument clus­
ter.
The fo llow ing systems are integrated in the ESC :
Ant i-loc k brake system (ABS)
ABS preve nts the wheels from locking up when
braking. The veh icle can still be steered even dur­
ing hard brak ing. Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pulsing in
the brake pedal indicates that the system is help ­
i n g you to brake the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases braking power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the b rake pedal
until the situa tion is over. In vehicles w it h adap­
tive c ruise contro l* , the brake assist system is
mo re sensit ive if the di stance de te cte d to the ve­
h icle ahead is too small.
Anti -slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin to spin and adapts t he force to the road
conditions . This makes it easie r to sta rt, acceler­
ate and dr ive up h ills.
Electronic differential lock (EDL )
The EDL brakes w heels that a re spinning and
transfers the drive power to the other whee ls .
This f unction is not avai lab le at higher speeds.
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
186
overheating . EDL will sw itch on again automati ­
ca lly when conditions have returned to normal.
Steering recommendation
The ESC he lps to s tabilize the vehicle by chang ing
t h e s teer ing torque.
On vehicles with dynam ic steeri ng*, ESC helps
stab ilize the steer ing in crit ica l sit uat io ns.
Selective wheel torque control
Se lective wheel torque cont rol is used when driv­
i ng on curves. The front whee l on the inside of
the curve or both wheels on the inside of the cu rve are braked se lectively as needed. This al­
l ows mo re precise dr iving in c urves . The applica­
ble system may not ac tiv ate when d riving in wet
o r snowy cond it ions.
_&. WARNING
- The ESC and i ts in teg ra ted systems can not
overcome the laws of physics . This is espe ­
cially important on slippery or wet roads. If
the systems begin act ing to stab ilize your
veh icle, you should immediately change
your speed to match the road and traffic conditions. Do not let the increased safety
provided by t hese systems tempt yo u to
take risks. Doing so will i ncrease the r isk of
a loss of vehicle con trol, collisi on and se ri­
ous person al injur ies.
- Always a dapt your speed to road, traffic and
weather condi tions. The risk of los ing c on­
t rol of the vehicle in creases w hen driving
too fast, es pecially through curves and on
slippe ry or wet roads, and when driving too
close to ve hicles up ahead. The ESC and its
integ rated systems cannot always prevent
col lisions - there is still a risk of accidents!
- Always accelerate w ith special care on even,
smooth su rfaces s uch as those that are wet
or covered wit h ice and snow. The drive
wheels can spin even w it h these assistance
sys tems t hat cannot a lways help to reduce
t he risk of loss of vehicle co ntro l.

-Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat shields. During dr iv ing, the substance
used for undercoating could overheat and
cause a fire.
Q) Note
- Be aware that just one tank filling with
leaded fuel will already ser iously degrade
t h e pe rformance of the catalytic converter .
- Do not exceed the correct eng ine o il level
c:> page 221.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic conve rte r to overheat.
- Do not tur n off the ignition whi le the vehicle
i s mov ing.
- Do not continue to operate your vehicle un­
der these cond it ions, as otherwise fuel can
r each the catalytic converte r. This cou ld re­
su lt in ove rheating of the converte r, req uir­
i ng its replacement.
- To assu re efficient operation of the Emis ­
s ion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission control system
and co uld lead to damage.
@) For the sake of the environment
Even when the Em ission Control System is op­
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states. This depends on the su lfu r
conten t of the fuel being used. Using a differ­
ent brand of fue l may he lp, or filling the tan k
with lead -free s uper grade gasoline.
Driving and the envir onment
Diesel particulate filter
App lies to : veh icles w ith diesel en gine
The diese l particu late filter filters near ly all of
the soot particles out of the exhaust. The filter
cleans itself automatica lly under norma l driving
condit ions. If the filter cannot clean itself (for ex­
amp le, because you are only driving short distan­
ces), the filter becomes clogged with soot and
the m symbol for the d iesel part icu late filter il­
luminates
c:> page 31 .
_&. WARNING
-Do not park your veh icle over flammab le
mate ria ls s uch as grass or leaves because
the high temperature of the diesel particu­
late filter cou ld start a fi re.
-
- Do not app ly an underbody pro te ctant in the
exhaust system area or a fire could sta rt .
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
ly ing parts such as spo ilers and exhaust system
parts do not bottom out and get damaged .
This is especially true for vehicles with low-s lung
chassis (sports chass is)* and fully loaded
vehicles.
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels .
Fuel economy, env ironmental impact, and wear
o n your engine, brakes and tires large ly depend
on three factors :
- your pe rsonal d riving s tyle
- operat ing cond itions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your fuel
195

Driving and th e en vironm ent
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­
ronment and your pocketbook.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depend ing upon vehicle
load and speed, road and weather conditions,
trip length, etc .
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
"'Avo id unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving a t moderate speeds saves fuel and im­
proves your mileage .
"'Try and keep well below your car 's maximum
speed .
Accelerating gent ly reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fue l cons umption, exhaust emissions and engine
noise increase d isproportionately at high speeds .
If you drive at approximately three q uarters of
top speed, fuel consumpt ion w ill be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.

· Reducing unnecessary idling
E ven when your car is just idling it burns up fuel .
"'Shut the engine off when you are not driving
the vehicle.
"' Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi­ c ient to sw itch off the engine in vehicles without
the Start-Stop-System* when stopped at ra ilroad
cross ings and long red lights. Turning the engine
off fo r just 30-40 seconds saves more fuel than is
bur ned by s tarting the engine again .
It takes a long time for the engine to warm up
fully when it is runn ing at id le . However, wea r
and noxious emissions are especially high when
the engine is warming up . So yo u should dr ive
away as soon as you sta rt the eng ine and avo id
running at hig h rpms whi le the engine is st ill
warming up .
Q) Note
Do not leave eng ine idling una ttended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go
unheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
· Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
"' Have your vehicle serviced at regular interva ls.
By having your vehicle regular ly serv iced by an
authorized Audi dea le r helps to ensure that it
r uns prope rly and economically . The condition of
your vehicle not on ly affects its safety and ability
to hold its value, it also affects
fuel consump­
t ion .
Check your oil each time you fill your tank.
The amou nt o f oi l used is related to engine load
and speed. ..,

Trailer towing
Sp eed
The higher the speed, the more d ifficult it be­
comes for the driver to contro l the rig. Do not
dr ive at the maximum permissible speed. Reduce
your speed even more if load, w eather or wind
conditions are unfavorable -particularly when
going downhill.
Red uce vehicle speed
immediatel y if the trai le r
shows the s lightest sign of swaying .
Do not try
to stop the swayin g by ac cele rating.
Observe speed limits . In some areas, speeds for
vehicles towing trailers are lower than for reg ular
ve hicles.
A lways apply b rakes early . When dr iving down­
hi ll, shi ft into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes a lone can cause them to overheat and fail.
Coolant temperature
The coolant temperatu re gauge ¢ page 8 must
be observed ca refully . If the needle moves close
to the upper end of the scale, reduce speed im ­
mediately and/or turn off the air conditioner .
I f t he coolan t temperature warn ing light i n the
instr ument cluster s tarts flashing ., pull off
the road, stop and let the engine
idle for about
two minutes to prevent heat bu ild-up .
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent . Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi .
Trailer towing
information
Important to know
Your veh icle hand les different ly when tow ing a
tra iler because of the additional weight and dif ­
fe rent weight d istr ibut ion . Safety, performance
and economy w ill great ly depend on how careful­
ly you load you r trailer and operate your rig .
202
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic . Keep pract icing unt il yo u h ave be ­
come comp lete ly familiar w ith the way your vehi­
cle-tra iler combination behaves and responds.
Backing up is difficult and requires practice .
Backing up w ith a trailer generally req uires steer ­
i ng action opposite to that when backing up your
vehicle without a trailer.
Maintain a greater distance between your vehicle
and the one in front of you . You will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot accel­ erate as fast as you normally wou ld because of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
- If you tow a trai ler, your Audi may requi re
more frequent maintenance due to the ex­
tra load ¢
page 2 76.
' Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot bra ke .
.,. Have someone place cho cks under bot h the ve­
hicle and the trailer wheels .
.,. With choc ks in place, slowly release the brakes
until the wheel chocks absorb the load.
.,. Turn the wheels towards the curb .
.,. App ly the parking brake .
.,. Move the selector lever to P .
When restarting after parking :
.,. App ly the foot brake .
.,. Start the eng ine .
.,. Move the se lector lever to D/S.

Checking and Filling
cooling system is not leakin g, a loss can come
from t he coolant boiling through overheat ing
an d be ing pushed out o f the coo ling system .
A WARNING
-
-The cooling system is under pressure. Do
not open t he coolant expansion tank ca p
when the eng ine is hot. This inc reases the
risk of bu rns .
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o rigina l container
and away from children. There is a risk of
po isoning .
- When working in the eng ine compartmen t,
r emembe r that the rad iator fan ca n switch
on even if the ign ition is swi tc h ed off, which
in creases the risk of in jury.
(D Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case , do no t
cont inue driv ing. See an authorized Audi deal­
er or author ized Audi Se rvice Facility for assis­
tance .
