T he warning/indicator light (E lectronic Power Control) illumi -
nates when you turn o n the ignition as a function chec k.
[ i ] Tips
If this warning/indicato r light ill uminates while you are driving, then
there is a malfunct ion in the engine e lectron ics . Have the malfunct ion
co rrected as soon as possib le by yo ur autho rized Audi dealer or qua l­
ified workshop .•

Glow plug system
The control light illuminates when the glow plug system
is active.
If the indicato r ligh t illum inates, the g low p lug system is active .
You should start the eng ine immed iate ly after the ind icator light
switches off. The ind icator ligh t only illumina tes for approximately 1
second if the engine is warm or if the outside temperature is above 46
2F (8 2C).
(I] Tips
• If the glow plug indicator light illuminates while driving, there is
an engine control malfunction. The engine should be checked imme­
diately .
• If the indicator light does not ill uminate at all when switching the
ign ition on, the re may be a ma lfunction in the glow plug system. The
engine should be checked .•
Electronic stabilization program (ESP) ~ / t:.
This warning/indicator light monitors the electronic
stabilization program .
If the indicator lamp blinks w hile driving, the ESP or ASR (Anti-Slip
Regulation) is actively regulat ing .
If the ~ indicator lamp illuminates, the system has switched the ESP
off. In this case , you ca n swi tch t he ignition off and then on to swi tch
the ESP on again. The system is functioning completely when the
ind icator lamp sw itches off.
If the ind icator lamp illuminates, the ESP was switc hed off w ith the
I~ OFF! button .
ESP/ ABS fault ! See own er' s manual
If the • indicator lamp and the ~ ABS indicator lamp illuminate and
the d river message appea rs, the ABS or e lectronic differentia l lock is
ma lfunction ing . This also interrupts the ESP . The brakes still funct ion
w ith their normal power, but ABS is not act ive .
Dr ive to your author ized A udi deale r immediately to have the
malfunction corrected.

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event. ED Rs are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED Rs that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic control modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General information
The ESP improves the vehicle stability.
Fig. 222 Center
console with ESP
switch
ESP is des igned to help you maintain vehicle control in situations
where the car approaches the limits of "grip", especia lly when accel­
erating and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­
ment data provided by high performance sensors. The rotational
speed of the vehicle about its vertical axis, veh icle acceleration in the ...

fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabi lized by the forces acting on the whee l during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are main ly applied on the wheel that is on the
outs ide of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied as needed
on the wheel that is on the inside of the curve or additionally on the
other wheels. An acoustic s ignal indicates when ESP brake application
cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system ~
page 260 . If the Anti -Lock Brake System
(ABS) ma lfunctions, the ESP wi ll be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
wi ll perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode .
Offroad mode
ESP should normally be operated in normal mode because this
ensures maximum vehicle stability. If necessary, you can activate the
ESP offroad mode by pressing the button=>
page 256, fig. 222 to
obtain maximum traction and braking ability when driving off paved
roads at low speeds. In ESP offroad mode, the indicator light illu­
minates and the message
ESP Offroad Caution! Limited driving
stability
appears briefly in the d isp lay.
The ESP offroad mode can be useful in the following exceptiona l situ­
ations when slip or a highly effe ctive different ial loc king funct ion is
desirable. Examples:
Controls and equip­ ment Safety first Vehicle operation
•
when driving w ith tire chains,
• when driving in deep snow or on loose ground,
• when driving on uneven surfaces with the wheels severely
unloaded (articulation), and
• when rocking the vehicle loose a fter it has become stuck.
When the unusual situation is past, you should sh ift back to the
normal ESP operating mode by pushing the button again. The
message
ESP/ ASR on then appears briefly in the display.
Hill descent control
The hill descent control is switched on in ESP offroad mode. When
slowly descending steep gradients on loose ground or when the axles
are art iculated, hill descent control provides assistance by automati­
cally applying the brakes to keep vehicle speed constant. The vehicle
is also rende red easier to steer by select ive distribution of braking
force. Hill descent control intervenes when:
• the accelerator pedal is not pressed,
• the vehicle is travelling less than 12 mph (20 km/h),
• a steep gradient is detected,
• wheel behavior indicates loose ground or conditions with poor
adhesion (e.g. also axle articulat ion).
Hill descent control operates both dr iving forward and in reverse.
Active hi ll descent control is deactivated by pressing the accelerator
pedal until the conditions for activation already listed are met aga in.
& WARNING
• The Electronic Stabilization Program is nevertheless subject to
the laws of physics . It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. ..

& 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 260. 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 spin ning wh en 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 260, 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 gri p to lock onto
the road s urface. The system is active ac ross the en tire speed range .
