B Air suspension: malfunction! Safely stop ve-
hicle.
Steering and ground clearance limited
There is a malfunction. Do not continue driving.
Secure the vehicle against rolling before exiting
the vehicle > page 91. Avoid turning the steering
wheel, because the vehicle ground clearance may
be so low that turning the steering wheel could
result in damage to the wheels and wheel hous-
ings.

There is a malfunction. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.
B Air suspension: vehicle too low. Limited
ground clearance
The vehicle ground clearance is very low. Wait un-
til the air suspension system has restored normal
ground clearance. Have an authorized Audi dealer
or authorized Audi Service Facility repair the mal-
function immediately if the indicator light does
not turn off after a significant period of time.

Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.

1} Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.

There is a malfunction in the steering system.
Steering may be more difficult or more sensitive.
Adapt your driving style. Have the steering sys-
tem checked immediately by an authorized Audi
dealer or authorized Audi Service Facility. Please
note that the red indicator light may turn on af-
ter restarting the drive system. Do not continue
driving if it does.

the malfunction repaired.

ZA WARNING
Do not tow your vehicle if there is a malfunc-
tion in the electronic steering lock because
this increases the risk of an accident.
@ Tips
If the & or el indicator light only stays on
for a short time, you may continue driving.

All wheel drive (quattro)
Applies to: vehicles with all wheel drive
The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
=> page 106.
The all-wheel drive system is designed for high
motor power. Your vehicle is exceptionally power-
ful and has excellent driving characteristics both
under normal driving conditions and on snow and
ice. Always read and follow safety precautions
oA.

ZA WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the motor RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.

Messages
BH all-wheel drive: malfunction! Limited stabil-
ity. Please contact Service
Driving stability is reduced. Continue driving with
caution. Drive to an authorized Audi dealer or au-
thorized Audi Service Facility immediately.
Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such oversteering and understeering of
the vehicle, the drive wheels spinning, or the risk
of the vehicle tipping.
The brakes are applied or the motor torque is re-
duced in order to stabilize the vehicle.
The following stabilization functions are integrat-
ed into the ESC, among others:
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.
Noises will indicate when the system is working.
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.

Driving dynamic


ZA WARNING
— When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin
and the vehicle could swerve, especially on
slick or slippery road surfaces. When there is
a heavy vehicle load and sudden driving ma-
neuvers, it may not be possible to prevent
the vehicle from tipping under certain cir-
cumstances, which increases the risk of an
accident.
— Because of the increased risk of an accident,
only drive with the ESC switched off or limit-
ed when it is necessary. Reactivate the ESC
as soon as possible.

@) Tips
— If you select the Audi drive select* offroad
mode, hill descent assist will switch on.
— If the ESC is limited, switched off, or mal-
functioning, systems with an automatic
braking intervention function may not be
fully available.
— If malfunctions occur in other systems or
certain driver assist systems are active, the
ESC must be switched on by the system. The
ESC
may switch on automatically and can-
not be operated with the button.
BA fs i BB & Stabilization control (ESC/
ABS): malfunction! See owner's manual
There is a malfunction in the ABS or EDL. This al-
so causes the ESC to malfunction. The brakes still
function with their normal power, but ABS is not
active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
Other indicator lights
ira blinks while driving, the ESC is actively reg-
ulating. Operating noises may occur. If the indi-
cator light stays on, the ESC has been switched
off due to system needs. The indicator light turns
off when the system is fully functional.

Manually releasing the charging connector
If you are not able to pull the charging connector
out of the vehicle charging port, there may bea
malfunction. You must use the emergency re-
lease to release the vehicle charging connector.
Requirement: the “P” gear must be selected and
the vehicle must be unlocked.
> End the charging process > page 113.
> Open the hood = page 234.
> Open the cover in the motor compartment on
the side of the applicable charging port.

tainer and then pull on the loop carefully >@.
» Remove the charging connector.
> After releasing manually, secure the loop on
the retainer and close the cover.

ized Audi Service Facility immediately to have
the malfunction corrected.
If the charging connector still cannot be removed
after using the emergency release, see an author-
ized Audi dealer or authorized Audi Service Facili-
ty for assistance.
@) Note
Only pull on the loop until you feel resistance.
You
will not hear it release. If you continue to
pull, you could damage the emergency re-
lease mechanism.

bending, and crushing.
— Do not submerge the charging equipment in
water and do not cover it with snow or ice.
— When you remove the charging cable from the
vehicle and from the power supply, only pull at
the connectors and not at the cable.
— Put the cap on after using the charging cable.
