Audi drive select
Introduction
Applies to: vehicles with Audi drive select
Audi drive select alLows you to use different set­
ups on your vehicle. The modes efficiency*, com­
fort, auto and dynamic allow the driver, for ex­

ample,
to change from a sporty mode to a more
comfortable one via the
&&
button in the centre
console or via the infotainment system. In
addi­

tion,
the individual* mode allows you to adapt
the vehicle set-up to
suit
your personal driving

style.
For example, you might choose to combine
a more dynamic engine set-up with a lighter
steering response.
Description
Applies to: vehicles with Audi drive select
The possible vehicle set-up in each mode de­
pends on which equipment is installed on your
vehicle. The engine and steering are basic parts
of your vehicle which are always included in the

set-up.

Engine and automatic gearbox*
The response of the engine and automatic
gear­

box* to accelerator pedal movements will be
more spontaneous or balanced, depending on
131

Driver assist systems
which mode you select. In the performance-
oriented dynamic mode, the automatic gearbox
changes gear at higher engine speeds.
By contrast, in efficiency* mode, the automatic
gearbox* selects the next gear at lower engine
speeds and the coasting mode is activated

^>page
91. This helps to reduce fuel consump­

tion.

Suspension control (Audi magnetic
ride)*

The suspension control uses sensors to collect in­
formation on steering movements, braking and
acceleration input by the driver, road surface
quality, road speed and vehicle Loading. With
Audi drive select you can choose between dynam­
ic and comfort-oriented suspension set-ups (dy­
namic and comfort modes), or opt for
a
more
balanced set-up (auto mode).
Steering
The degree of power assistance can be varied.
Various modes are possible
^>page
133. The
light, indirect steering response in comfort mode
is particularly suitable on long motorway trips,
for instance. The steering has a tighter, more di­
rect feel in dynamic mode.
The steering response is even more agile on
vehicles with progressive steering*.
Audi adaptive light*
The adaptive light system adjusts the light distri­
bution according to the mode selected.
Air conditioner*
The air conditioner runs in a particularly econom­
ical mode when the efficiency* setting is selec­

ted.
When this function is selected, eco* is shown
in the display of the automatic air conditioner.
Cruise control system*
The acceleration response is particularly econom­
ical in efficiency* mode.
Audi adaptive cruise control*
The acceleration mode can be varied from com­
fort to sport by changing the setting in drive se­
lect. The setting also determines whether the re­
sponse of the adaptive cruise control to the driv­
ing style of the driver in front is more balanced or
spontaneous. The efficiency* mode chooses a set­
up for maximum economy.
© Note
- On some models the vehicle's maximum
speed can only be obtained in the auto and
dynamic modes.
- Applies to vehicles with manual gearbox: An
E appears in the gear-change indicator when
efficiency* mode is activated.
- Applies to vehicles with automatic gearbox:
Selector lever position
S
is automatically se­
lected when dynamic mode is activated.
E
is
selected in efficiency* mode.
- Applies to vehicles with automatic gearbox:
If
you
select efficiency* mode when the se­
lector Lever is in position D,
E
will automati­
cally appear in the instrument cluster dis­
play.
- Applies to vehicles with manual gearbox: If
you press the accelerator right down past
the point of resistance in efficiency* mode,
the engine power is automatically control­
led to give your vehicle maximum accelera­

tion.

- Please note that the efficiency* mode is not
available in towing mode.

General notes
Applies to: vehicles with rear parking aid/parking system
plus/reversing camera/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicLe.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car

cépage
135.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicLe

^page
135.
The reversing camera uses the infotainment sys­
tem display to show a picture of the area behind
the vehicle captured by the camera. This picture
helps you to park the vehicle parallel or perpen­
dicular to the roadside. In addition, you are assis­
ted by the functions of the parking system plus

^>page
137.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicLe into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb

A
WARNING
- Always watch the road and the area sur­
rounding the vehicLe. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­

vres.

- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system - risk of accident!
- The sensors and cameras have bLind spots in
which neither people nor objects are regis­

tered.
It is particularly important to ensure
that there are no small children or animals
near the vehicLe - risk of accident!
- Always keep a close watch on the area
around the vehicLe and make full use of the
rear-view mirrors.
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.

(T)
CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­

tures,
such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note
that
you will no longer
be warned about these obstacles.
- Remember to maintain sufficient clearance
from the kerb to avoid damaging the wheel

rims.

(T)
Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
-To familiarise yourself with the system, we
recommend
that
you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can change the display and adjust the
volume and pitch of the beeps

Intelligent technology
the standard tyres. Nevertheless, we still recom­
mend that winter tyres or all-season tyres should
be fitted on all four wheels when winter road
conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this
also applies to cars with four-wheel drive

Opcrge
309, Snow chains.
Replacing tyres
On vehicles with four-wheel drive, all four tyres
must have the same rolling circumference. Also
avoid using tyres with varying tread depths

tapage
305,
New wheels or tyres.
Off-roader?
Some models do not have enough ground clear­
ance to be used on rough tracks and uneven ter­

rain,
so it is best to avoid off-road driving.
A WARNING
- Even with four-wheel drive, you should al­
ways adjust your speed to suit the condi­

tions.
Do not let the extra safety provided
tempt you into taking any risks when driving
- this can cause accidents.
- The braking ability of your car is limited by
the grip of the tyres. In this respect, your
car is no different from a car without four-
wheel drive. So do not be tempted to drive
too fast on icy or slippery roads just because
the car still has good acceleration in these
conditions - risk of accident!
- On wet roads bear in mind that the front
wheels may start to "aquaplane" and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as with a front-wheel drive car. So do
not drive too fast in the wet: adjust your
speed to suit the conditions (accident risk).

Power management
This system helps to ensure reliable
starting

The
power management controls the distribu­
tion of electrical energy and thus helps to ensure
that there is always enough power available to
start the engine.
If
a
vehicle with a conventional electrical system
is left parked for
a
long time, the vehicle battery
will gradually lose its charge because certain
electrical equipment (such as the immobiliser)
continues to draw current even when the ignition
is off. In some cases there may not be enough
power available to start the engine.
Your vehicLe is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the vehicle battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the vehicle battery. Sensors
detect the battery voltage, battery current and
battery temperature. This enables the system to
calculate the current power level and charge
con­

dition of the vehicle battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It
con­

trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power Level of the vehicle bat­
tery, the individual electrical components are
switched off one after the other to prevent the
vehicle battery from losing too much charge and
to ensure that the engine can be started reliably. •

Airbag system
Airbag system
Description of airbag
system
General notes on airbag system
The airbag is an integral part of the car's passive
safety system.
In conjunction with the three-point seat belts,
the airbag system gives the front occupants
addi­

tional protection for the head and chest in the
event of a severe frontal collision.
In a severe side collision the side airbags and the
head-protection airbags reduce the risk of injury
to the occupants
•=>
A-
In addition to their normal function of protecting
the occupants in a collision, the seat belts also
hold them in a position where the airbags can in­
flate properly and provide maximum protection.
The airbag system will only work with the
igni­

tion on. The airbag system is monitored electron­
ically; the airbag warning lamp indicates whether
the system is functioning properly.
The main parts of the airbag system are:
-The electronic monitoring system (control unit
and sensors)
- The two front airbags
- The front side airbags
-The head-protection airbags
- The indicator Lamp
Q
in the instrument cluster
There is a fault in the airbag system if the
warning lamp
- does not come on when the ignition is switched

on.

- does not go out about 4 seconds after the
igni­

tion is switched on.
- goes out and then comes on again after the ig­
nition is switched on.
- comes on or flickers while the car is moving.

A WARNING
- The airbags are not a substitute for the seat

belts;
they are an integral part of the car's
overall passive safety system. The airbags
can only offer effective protection if the oc­
cupants are wearing their seat belts. For
this reason it is very important to wear the
seat belts at all times
^>page
275, Why is it
so important to use seat belts?.
The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly
^>page
58, Front seats.

•
If you do not wear a seat belt, if you lean

forward,
or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the airbag system be
triggered in an accident.
Components of the airbag system are loca­
ted in various parts of the vehicLe. If repairs
to other vehicle components make it neces­
sary to perform work on the airbag system
or to remove or install parts of the airbag

system,
this may cause damage to the air-
bag system. As a result, the airbags may not
inflate correctly or may not be triggered at
all in an accident situation. For this reason,
you should always have the work carried out
by a qualified workshop.
If a fault should occur in the airbag system,
have the system checked immediately by a
qualified workshop. Otherwise the system
may fail to trigger in an accident.
Do not attempt to modify components of
the airbag system in
anyway.

Never make any alterations to the front
bumper
or
the body.
Do not remove the front seats.
The airbag system can only be activated

once;
if the airbag has been triggered, the
system must be replaced. Should the airbag
system or airbag modules have to be re­

placed,
the qualified workshop carrying out
the replacement will document all details.

•
If any repair work is required
or
the airbag
and restraint systems have to be replaced,
have the work carried out by your authorised
Audi dealer or a qualified workshop which
adheres to the Audi factory standards. This
will minimise the risk of injury.
If you sell the vehicle, remember to pass on
the complete Service Wallet to the new
owner. If any of the airbags have been
