2010 AUDI A5 COUPE differential

Instruments and warning/indicator lights
switch the ESP on again . The system is functioning completely
when the indicator lamp switches off.
If the indicator lamp illuminates, the ESP was switched off with
the !ESP
O FF J button.
ESP / ABS fault ! See owner's manual
If the indicator lamp and the ABS indicator lamp illuminate
and the driver message appears, the ABS or electronic differential
lock is malfunctioning. This also interrupts the ESP. The brakes still
function with their normal power, but ABS is not active.
Dr ive to your author ized Aud i dealer immediate ly to have the
malfunction corrected.

Airbag system
~i (USA models) / !l (Canada models)
This warning/indicator light monitors the airbag and the
pretensioner systems.
The I (USA models) t!! r (Canada models) warning light illuminates
for a few seconds each time you switch on the ignition.
If the m (USA models)
t!! r (Canada models) warning light does not
go out, or if it illuminates while you are driving, or if it starts to blink,
then there is a malfunction somewhere in the system . If the light
does not illuminate when you switch on the ignition, this a lso
means there is a malfunction.
& WARNING
If you have a malfunction in the airbag system, contact your autho­
rized Audi dealer immediately . Otherw ise the airbag or the belt
pretensioner may not work properly in an accident. •
Applies to vehicles: with tire pressu re mon itoring system
Tire pressure monitoring system -telltale
indicator lamp '
The warning/indicator light appears in the event of a
significant loss of air pressure.
The I L1 warning/indicator light illuminates for a few seconds after
the ignition is turned on as function check, and then goes out.
If the
1'· symbol appears, pressure is too low in at least one tire.
When the system detects a malfunction, the warning/indicator light
wi ll flash for approximately one minute and then remain continu­
ously illuminated. This sequence will continue upon subsequent
vehic le starts up as long as the malfunction exists. Contact your
authorized Aud i dealer and have the ma lfunction corrected.

Turn signals ¢ ¢
The indicator light blinks when you use either turn signal.
Whenever you use the left¢ or the right¢ turn signal, the indicator
light blinks. When you use the emergency flashers, both indicator
lights flash.
If one of the turn signal light bulbs burn out, the turn signal will
blink twice as fast as normal. •
Safety belts t
This warning/indicator light reminds you to put on your
safety belt.
T he t warning/indicator light i lluminates when the ignition is
switched on to remind the driver and (on USA models only) any front
passenger to put on the safety belt. Additionally, an audible warning
tone will also sound . _.,,

Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU is part of the On -Board Diag ­
nostic (OBD II) system. The symbol "' lights up when the ignition is
turned on and will turn off after the engine has started and has
settled at a constant idle speed. This indicates that the MIL is
working properly .
The warning light illuminates when there is a malfunction in the
engine electronic system. Contact your authorized Audi dealer and
have the malfunction corrected.

This warning/indicator light monitors the ABS and the
electronic differential lock (EDL).
The warning/indicator light will come on for a few seconds when the
ignition is switched on. The light will go out after an automatic
check sequence is completed.
There is a malfunction in the ABS when:
• The warning/indicator light does not illuminate when you switch
on the ignition .
• The warning/indicator light does not go out after a few seconds.
• The warning/indicator light illuminates while driving.
The brake system will still respond even without the assistance of
the ABS system. See your authorized Audi dealer as soon as
possible to restore full braking performance.
For more information
regarding the ABS~
page 238.
The ABS warning light and the brake warning light come on
together. The ABS will not work and you will notice a change in braking response and performance.
Malfunction in the brake system
If the brake warning light~ page 16and the ABS warning illuminate
together there may be a malfunction in the ABS, and there may also
be a malfunction in the brake system itself=}& .
In the event of a
malfunction in the brake system the warning/indi ­
cator light
BRAKE (USA models)/ ((D) (Canada models) in the instrument
cluster flashes. By pressing the [
SET) button, you can bring up a
driver message which explains the malfunction in more detail.

The system operates across the entire speed range in combination
with the ABS system. If the Anti -Lock Brake System (ABS) ma lfunc­
tions, the ESP wil l also shut down .
How the system works
The Anti -Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
th ese functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertica l axis, vehicle 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 continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stabi lized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (the vehicle turns too
sharply and the rear wheels slide toward th e ou tside of a curve), the
brakes are main ly app lied on the wheel that is on the outside of the
curve . In the case of a vehicle that is
understeering (the vehicle does
not turn sharply enough and pushes out of a curve), the brakes are
applied as needed on the wheel that is on the inside of the curve or
additional ly on the other wheels. An acoustic signal indicates when
ESP brake app lication cuts in=>&.
T he system operates across the entire speed range in combination
with the ABS system =>
page 238. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatica lly be activated
and will perform a se lf-test. As soon as the test is comp leted, the
system is in norma l operating mode.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
You
can activate a deactivated ESP or deactivated ESP/ASR if
required by pressing the::::>
page 234, fig. 215 ::::> page 234, fig. 214
button . When they are activated, the message
ESP /ASR on appears
briefly in the display .
Deactivating
The ESP should normally be activated al l the time. If necessary, you
can deactivate Anti -Slip Regu lation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button=>
page 234, fig. 215.
• Deactivating ASR: Tap the button . In certain exceptional situa­
tions (e .g. driving with tire chains), the Anti-Slip Regulation (ASR)
can be deactivated =>
page 236. The message ASR off appears in the
display as we ll.
• Deact ivating ESP/ASR Press the button for more than 3 seconds.
With the ESP/ASR deactivated, the indicator light comes on, see
=>
page 13. The message ESP switched off appears in the disp lay as
we ll.
& 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 Elec­
tronic Stabilization Program system to lull you into accepting
additional safety risks. •
