8/8 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 B indicator light turns on, ESC was
switched off using the |£*| button > page 87.


Stabilization control (ESC/ABS): malfunction!
See owner's manual
If the B indicator lamp and the fs / &) ABS 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 86.
<5 Engine control
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.
ON eae
If the A or indicator light turns on, check
the message in the instrument cluster.
— Tank system
AD} Please refuel
If the indicator light turns on for the first time
and the message appears, there are about 1.9 gal
(7 L) of fuel left in the tank.
la Please refuel immediately
If the indicator light turns on and this message
appears, the fuel tank is almost empty. Refuel
the vehicle immediately.
AN} Tank system: malfunction! Please contact
Service
If the indicator light turns on and this message
appears, there is a malfunction in the tank sys-
tem. Drive to an authorized Audi dealer or au-
thorized Audi Service Facility immediately to have
the malfunction corrected.
(@) For the sake of the environment
Fuel should never enter the sewer system or
come into contact with the ground.
G) Tips
For more information on fueling, see
=> page 224.
CCTM CU
If the 3 indicator light turns on, the washer flu-
id is almost out. Fill the washer fluid for the
windshield washer system and the headlight
washer system* when the ignition is switched off
=> page 238.
7! Windshield wipers
If the ke indicator light turns on, then there is a
windshield wiper malfunction. Drive to an au-
thorized Audi dealer or authorized Audi Service
Facility immediately to have the malfunction cor-
rected.
& Bulb failure indicator

If the ka indicator light turns on, a bulb has
failed. The message indicates the location of the
bulb.
Replace the bulb immediately.
Vehicle lights: malfunction! Please contact
Service
There is a malfunction in the headlights or the
light switch. Drive to an authorized Audi dealer or >

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 engine torque is re-
duced in order to stabilize the vehicle. When the
ESC engages, the B indicator light blinks in the
instrument 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 system
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 drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
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.
86
EDL will switch on again automatically when con-
ditions have returned to normal.
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

ZA 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. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!
