is displayed in the event of a fault,

the emergency assist functions are unavailable or

restricted.

Within certain limits imposed by the system, the

emergency assist is activated automatically if it

detects that the driver is inactive.

A driver message indicating the cause and possi-

ble remedy may appear for some of the displays.

To view further information, open the notifica-

tion centre on the centre display. The weather

conditions may not be good enough, or a sensor

may be obstructed. Clean the area in front of the

sensors ðpage 133. Check whether the issue

still occurs the next time you switch on the vehi-

cle.

If the vehicle is being driven manually without

any assist systems that intervene in the steering,

the time that passes before the driver is identi-

fied as inactive can be adjusted via the sensitivity

setting. The sensitivity can be adjusted in the

Driver assist menu  ðpage 134. Low sensitivi-

ty results in the emergency assist being activated

later if the vehicle is being driven manually with-

out any assist systems that intervene in the

steering.

If a fault persists, drive to a qualified workshop

soon and have it rectified.

Active front assist

Cancelling the emergency assist

Introduction

Some of the possible ways to cancel the emer-

gency assist are:

Within certain limits imposed by the system, the

active front assist can identify if there is a danger

of collision and initiate appropriate safety meas-

ures to avoid a collision occurring. You will be

alerted on the instrument cluster display when

the active front assist intervenes.

– Moving the steering wheel, or

– Applying the brake pedal, or

– Pressing the accelerator firmly.

When the vehicle is stationary, the emergency

assist can be cancelled by moving out of trans-

mission position P or by releasing the parking

brake ðpage 108.

In certain situations, functions of the proactive

occupant protection system may also be trig-

gered.



If you cancel the intervention by the system,

will light up and a corresponding message will

appear.

wards you or crosses the road into which

you are turning

The system may intervene when turning off

as soon as the vehicle is moving.

If you are travelling at a speed of up to ap-

prox. 25 km/h, the system can detect and re-

act to the following objects:

WARNING

Please note the safety precautions and system

limits of the supporting systems, sensors and

cameras ðpage 130 to ðpage 132.

– Oncoming vehicles in the opposite lane.

– The protection provided by the active front

assist is still subject to the prevailing physi-

cal limits. It is a driver assist function and

cannot prevent a collision in every situation.

The driver must always intervene personally.

It is always the driver's responsibility to

brake in good time. Do not let the extra

safety provided tempt you into taking any

risks when driving – risk of accident!

cluster and (if fitted) on the head-up display. If

the parking aid is activated, the symbol also ap-

pears on the centre display.

– Loose objects can be flung around in the

passenger compartment in the event of sud-

den driving or braking manoeuvres – risk of

accident! Stow objects away safely while the

vehicle is moving.

Collision warning

If a potential collision risk is detected, you will be

informed of this risk by a visual and acoustic

warning.

– If the system intervenes, there is a risk of in-

jury, especially if occupants are not sitting in

the correct position or not wearing a seat

belt. Ensure that all occupants have their

seat belts fastened correctly and are seated

properly as described in this manual

ðpage 63.

Brake jolt

In the event of an impending collision, an acute

warning may also be given in the form of a brake

jolt. You may need to take evasive action or brake

hard to avoid a collision.

– If the brakes are applied automatically when

towing a trailer, the behaviour of the trailer

under braking may be different than usual.

The reaction of the active front assist may

be restricted or the system may be unavaila-

ble if the vehicle is towing a heavy load.

Automatic brake pressure increase

If you do not brake hard enough in the event of

an impending collision, the brake pressure may

be increased automatically in certain situations.

Automatic braking

Overview of measures to avoid a collision

The system can, subject to general system limits,

apply the brakes heavily in order to avoid a colli-

sion or reduce the impact of a potential collision.

If the system brakes the vehicle to a stop, the ve-

hicle will then be held at a standstill. If the vehi-

cle cannot be held at a standstill, a driver

Only some of the measures may be activated de-

pending on the hazard situation detected. Some

functions may be modified or skipped.

The active front assist functions are unavailable if

 is displayed on the centre display, e.g. if the

message will appear and you must take control

of the vehicle.

– If the system is triggered at an undesirable

time on several occasions.

Swerve support

WARNING

If you take action to avoid an obstacle following

an acute warning, the swerve support will assist

you when you are steering the vehicle. As long as

you are steering actively, the function brakes in-

dividual wheels and applies a small steering im-

pulse to stabilise and, if necessary, correct the

evasive manoeuvre. The driver is responsible for

steering for the entire duration of the evasive

manoeuvre.

Undesired system interventions may result in

an accident. Do not use the system in situa-

tions where undesired system interventions

may occur.

Driver messages about the active front

If the system is switched off, it will be automati-

cally activated again the next time you switch the

vehicle on.

If the message is still displayed when you switch

the vehicle back on, drive to a qualified workshop

soon and have the fault rectified.

Dealing with undesired system

interventions

Rear turn assist

Undesired system interventions may occur in par-

ticular situations.

Using the rear turn assist

Audi recommends switching off the active front

assist in the following situations:

– If you are using the vehicle away from public

roads.

– If the vehicle is being towed away or loaded on-

to a transporter or similar.

– After an impact on components around the ra-

dar sensors, e.g. if the front of the vehicle has

been damaged in an accident.
