Audi drive select Driving settings
Introduction
Aud i drive select makes it possible to experi­
ence different types of vehicle settings in one
veh icle. The driver can select th ree
Comfort,
Auto
and Dynamic modes in the MMI to
switch between a sporty and a comfortable
driving mode.
You can also adjust the setting according to
your preferences in the
individual mode. For
examp le, you can combine settings such as a
sporty engine tuning with comfortab le steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury .
Description
The vehicle setup in each mode depends on
the vehicle's features. The engine, transm is­
sion, steering, reve rsible safety belt tension­
ers and adaptive air suspension are always in­
volved.
Engine and transmission
Depending on the mode, the engine and the
tra nsmission respond quicker or in a more bal­
anced manne r to acce lerator pedal move­
ments. In the sporty dynamic mode, the
transmission shifts at higher RPMs .
Air suspension
The adaptive air suspension/adaptive air sus­
pension sport*
( Air suspension in the MMI) is
an electronically con trolled air suspension and
damping sys tem. They are adjusted depend­
ing on the selected driving mode, the drive r's
steering, braking and acceleration input and
the road s urface, vehicle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport*.
Audi drive select 109
The vehicle clearance varies depending on the
selected mode and the speed .
T he hig hway setting is activated automatically
when you drive above 75 mph (120 km/h) for
more than 30 seconds in the
auto or dynamic
mode. The ground clearance is increased auto­
matically if the speed drops below 44 mph
(70 km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect stee ring that
moves easily, like the steering in comfort
mode, is best suited to long drives on a high­
way . In contrast, dynamic mode provides
sporty, direct steer ing .
The following applies to vehicles with dynamic steering* : the steering ratio changes based on
vehicle speed in order to ma inta in optimum
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is mo re direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuvering the vehicle. At low and average
speeds, dynamic steering additiona lly pro­
vides more responsive steering performance.
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
<:!) page 203, the Sport differen­
tia l* distributes the driving power to the rear
axle depending on the situation . The distribu ­
tion of power varies depending on the select ­
ed mode, from balanced (comfort) to agile
(dynamic). The goal is a high level of agility
and ability to accelerate on curves . The vehicle
is very responsive to steering.
Curve light*
The curve light adapts to driving on curves.
The pivoting act ion and the lighting are also
adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on .,..

110 Audi drive select
the drive se lect mode. Adaptive cruise control
a lso responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner.
Engine sound*
The sound of the engine is adapted to the se­
lected mode and ranges from subtle to sporty .
Q) Note
-Make sure there is enough clearance
above and below the vehicle when park­
ing. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance .
- When transporting the vehicle on a car
carr ier, tra in, ship or by other means, on­
l y tie the veh icle down at the running
surface of the tires, which is the outer
ci rcumfe rence . Securing the vehicle at
the axle components, s uspension str uts
or towing eyes is not pe rmitted because
the press ure in the air suspension s truts
can change during transport. The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you must activate the trailer ope ration mode
c:> page211.
(D Tips
-In some mode ls, the maxim um vehicle
speed can on ly be reached in the
auto
and dynamic modes.
- Se lecting the
dynamic mode results in
sporty shifting characteristics. The S
gear position engages automatically.
- In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the eng ine. This does not ind i­
cate a problem. -
In vehicles w ith sport different ia l* , the
dynamic mode is deactivated when tow­
ing a tra iler.
Selecting the driving mode
You can choose between Comfort, Auto , Dy­
namic and Individual.
Fig. 11 3 MMI : Drive select
.,. To select the mode, se lect the following in
the M Ml :

or Individual.
You can change the driving mode when the ve­
hicle is stationary or while driving. If traffic
permits, after changing modes, briefly take
your foot off the accelerator pedal so that the recently selected mode is also activated for
the engine.

Peripheral cameras
Introduction
Applies to vehicles: with top view camera system
In addition to the f unctions from the sensors
c::> page 122, Sensors, c::> page 124, Visual dis ­
play,
this parking system contains peripheral
cameras. Depending on the ve hicle equ ip­
ment, you are assisted by various
views such
as periphera l view, corner views at the front
and rear of the veh icle, and views di rectly in
fro nt of o r behind the vehicle.
General information
Applies to vehicles: with top view camera system
Fig. 138 Locat io n of peripheral cameras
Depending on the vehicle equ ipment, the pe­
ripheral cameras are found in the radiator
grille, i n the luggage compartment lid and on
both exterior mirrors
r:::;, fig . 138 . Make sure
that the lenses are not covered by deposits or
any other obstructions as it may impair the
system. For information on cleani ng, refer to
c::> page 218.
In the to p view mode, b lack corners are
shown in t he vehicle silhouette . Objects in
these areas are outside of the camera 's field
of
view and are not detected .
T he accuracy of the o rientation lines and the
blue surfaces is reduced if the adaptive air
suspension * is faulty, if the vehicle is lifted or
if the
dy namic mode is activated r:::;, page 109.
A WARNING
-- Always read and follow the applicable
warn ings
r:::;, & in General information on
page 121 .
-If the position or the installat io n angle
of a camera was changed, after a colli­
sion for example, do not continue to use
the system fo r safety reasons. Have it
checked by your author ized Audi deale r­
sh ip.
- Keep in mind that the image in the dis­
p la y is distorted if the exterior mi rror
housing has bee n manually adjusted .
- U se the
rear mode and the corn er view
( rear)
m od e only when the luggage com­
partment lid is fu lly closed . Otherw ise
the image in the display will be d istort­
ed .
- The vehicle surro undings are shown us­
ing the came ra images. The vehicle im­
age is shown by the system. Ob jects and
obstacles above the camera are not d is­
p layed.
- Camera lenses enlarge and distort the field of vision. The objects appear both
altered and inaccurate on the screen.
(D Note
- Always read and follow the applica ble
warnings
¢ (I) in General information on
page 121.
- The Infotainment d isplay shows the di ­
rection in which the rear of the vehicle is
traveling based on the steer ing whee l
ang le. The front of the vehicle front
sw ings out mo re than the rear of the
ve­
hicl e. M aintain pl enty of d istance so that .,_

and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this service for you .
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam­ ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used . It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per-
Airbag system 167
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­nally installed on your vehicle.
- Never use tire-rim combinations that have not been approved by Audi.
A WARNING
Items stored between the safety belt buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig . 169 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig . 169, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver 's and passenger's knees and up­
per and lower thigh areas and supplements
the protection provided by the safety belts.

208 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 87.
(1) Tips
-Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they a re ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
t hu s, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.
