Instrument cluster

Do not switch the ignition off because you may
not be able to switch it on again.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
& Engine start system: malfunction! Please
contact Service
There is a malfunction in the engine start system.
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
*\ Engine stop while driving
If the S indicator light turns on, there may bea
malfunction in the engine or fuel supply.
More force is needed to steer and brake the mov-
ing vehicle when the engine is stopped. If the ve-
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.

ZA\ WARNING
If the engine stops while driving, you will need
to use more force to brake the vehicle. This in-
creases the risk of an accident. There will still
be power steering if the ignition is switched
on while the vehicle is rolling and there is suf-
ficient battery charge. Otherwise, you must

use greater force when steering.

53/8 Electronic Stabilization Control (ESC)

If the B indicator light blinks while driving, the
ESC or ASR (Anti-Slip Regulation) is actively regu-
lating.
If the BB indicator light turns on, the system has
switched the ESC off. In this case, you can switch
the ignition off and then on to switch the ESC on
again. The indicator light turns off when the sys-
tem is fully functional.
If the [J indicator light turns on, ESC was
switched off using the |2%] button > page 705.


Stabilization control (ESC/ABS): malfunction!
See owner's manual
If the B indicator lamp and the ES / Gass in-
dicator lamp turn on and the driver message ap-
pears, the ABS or electronic differential lock is
malfunctioning. This also causes the ESC to mal-
function. The brakes still function with their nor-
mal power, but ABS is not active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
@ Tips
For additional information on ESC and ABS,
see > page 104.
If the B indicator light turns on if there is a mal-
function in the engine control. Drive slowly to an
authorized Audi dealer or authorized Audi Service
Facility to have the engine checked.
§ Suspension control
Applies to: vehicles with Audi drive select
If the | 8 | indicator light turns on, then there is a
malfunction in the suspension control. Drive im-
mediately to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
repaired.

Electronic Stabilization
Control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the motor torque is reduced
in order to stabilize the vehicle. When the ESC
engages, the B indicator light flashes in the in-
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake assist
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
104
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
