Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries depending on these­
lected mode and the speed .
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
au to or dynamic
106
mode. The ground clea rance 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 rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is more d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_

Engine sound *
The sou nd of the engine is adapted to the select­
ed mode and ranges from subt le to sporty.
(D Note
- Make sure there is enough cle arance above
and below t he vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature f luctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, tra in, ship or by other means, only t ie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspe ns ion struts or towing eyes is
not permitted be cause the press ure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens .
-If yo u are going to tow a tra ile r, you m ust
activate the trailer operation mode
<:!;>page 202.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto and
dynamic modes.
- Se lecting the
d ynami c mode resu lts i n spor­
ty shifting characteristics. The S gear posi­
tion engages a utomatically.
- In vehicles that have dynamic steering*, op ­
erating noise is heard when starting or stop­ ping the engine. This does not indicate a
problem.
Audi driv e se lect
- In vehicles w ith sport differential*, the dy­
namic mode is deactivated when towing a
trailer .
Selecting the driving mode
You con choose between Comfort, Auto , Dynamic
and Individual .
Fig. 116 MMI: Dr ive select
.,. To select the mode , select the follow ing in the
MMI: ICAR !function button>
Comfort , Auto ,
Dynamic or Indi vidual.
You can change the driv ing mode when the vehi­
cle is stationary or while driving . If traff ic per­
mits, afte r changing modes, briefly take your
foot off the accelerator pedal so that the recently
selected mode is also activated for the engine.
comfort -provides a comfort-oriented vehicle
setup and is suited for long drives on h ighways.
auto -provides an overall comfortable yet dy­
nam ic dr iving feel and is suited for every day use.
dynamic -gives the driver a sporty driving fee l
and is suited to a sporty driving style.

Airbag syste m
@ For the sake of the en vironment
Undep loyed airbag modu les and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regu lations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requirements and we recom­
mend 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
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the stiffness of the suspens ion,
including the spr ings, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preven t the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac­
teristics as the components originally insta l­
led on your veh icle .
- Never use tire-rim comb inations that have
not been approved by Audi.
160
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 electronic contro l module and prevent
the Advanced A irbag System from wo rking
p roperly.
- Always make sure that noth ing can inte rfe re
w ith the safety belt buckles and that they
are not obst ructed.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 167 Driver's kn ee ai rbag
The driver knee airbag is in the inst rument panel
u nderneath the s teer ing whee l
~ fig. 16 7, the
airbag fo r the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itiona l protection to
the d river's and passenge r's knees and uppe r and
l ower thigh areas and supp lements the protec ­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags a lso
deploy in frontal coll is ions when the deployment
th reshold stored in the control unit is met
~ page 154, More important things to know
about front airbags.
In add ition to their normal safe ty f unct ion, safe-
ty belts help keep the driver or front passenger in ..,

Trailer mod e
conditions are unfavorable - particularly when
going downhill.
Red uce veh icle speed
imm ediatel y if the tra ile r
shows the s lightest sign of swaying.
Do not try
to stop the sway in g b y accele rating .
Observe speed lim its . In some areas, speeds for
ve hicl es towing tra ilers are lower than for reg ula r
veh icles.
A lways apply brakes early . When dr iving down­
h ill , sh ift into a lower gear to use the engine
b raking effect to slow the veh icle. Use of the
brakes a lone can cause them to overheat and fail.
Air suspension*
When driving with a tra iler, activate the trailer
mode of the air suspension . Switch the air sus­
pens ion tra iler mode on when you a re towing a
tra ile r. This will limit the regulat ion by the air
suspens ion while driving . Select in the MM I:
ICARI function button > (Car )* sys tem s control
button >
Vehicle setting s > Air su sp .: to wi ng >
On .
Coolant temperature
The coolan t temperature gauge¢ page 10 must
be observed carefully. The coo lant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed
immed iate ly if the LEDs in the top part of the dis­
p lay turn on.
For more information about indicator lights, re­
fer to.
¢page 15.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
Your vehicle hand les different ly when towing a
trai ler because of the additiona l weight and dif­
ferent weight distr ibut ion. Safety, performance

-
and economy will g reatly depend on how carefu l­
l y you load your trai ler and operate your rig .
Befo re yo u actually tow yo ur t railer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep practicing unti l you have be ­
come complete ly familiar with the way your vehi­
cle-tra iler combination behaves and responds .
Backing up is diff icult and requ ires practice.
Backing up with a trailer genera lly req uires steer ­
ing action opposite to that when backing up your
vehicle witho ut a trailer .
Maintain a greater distance between yo ur vehicle
and the one in front of you. You will need more
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember tha t you canno t accel­
erate as fast as you normally wou ld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer du ring the break-i n pe ri­
od of your vehicle.
- If you tow a tr aile r, your A udi may requi re
more frequent ma intenance due to the ex­
tra load ¢
page 281.
Parking on a slope
Do not park on a slope with a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace chocks unde r both the ve­
hicle and the trailer wheels .
.,. With chocks in place, slowly release the brakes
until the wheel chocks abso rb the load .
.,. Turn the whee ls towards the curb.
.,. App ly the parking brake .
.,. Select the P selector lever posit ion.

Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel.
.,. After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop¢.,&. .
.. All passengers should
leave the car and move
to a safe location (for instance, beh ind the
guardrail) ¢.,&. .
.,. Engage the
parking brake to prevent your vehi­
cle from rolling unintentionally ¢.,&. .
.. Move

..&, WARNING
You or your passengers could be injured wh ile
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the
emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wa it in a safe
place away from the vehicle and well away
from the road and traffic.
- T o help prevent the vehicle from moving
sudden ly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­
ing changed. When one front wheel is lifted
off the ground, plac ing the Automatic
Transmission in "P" (Park) will
not prevent
the vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm . If necessary, use a
sturdy board under the jack .
- Always store the vehicle tool k it, the jack
and the replaced tire in the luggage com­
partment ¢
