Automatic transmission
Introduction
Your vehicle is equipped with an electronically­
controlled DSG transmiss ion called S tronic. Two
independent clutches transfer the power be­
tween the engine and transmission . It allows the
vehicle to accelerate without a noticeab le inter­
ruption in traction.
The transmission upshifts or downsh ifts auto­
mat ica lly. The driving style continuously influen­
ces the selection of the driving program.
When a
mod erat e d rivin g sty le is used, the
transmission selects the most economical d riving
mode. The transmiss ion upsh ifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transm ission switches to a spo rty mode after
a kick-down or when the driver uses a
s po rt y
d riv ing sty le
characterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually ( tipt roni c mod e).
Selector lever positions
Fig . 70 Instrumel'lt cluster: selector lever positions
The Infotainment system d isplay shows the cur­
rent se lector lever position and the engaged
gear.
P -Pa rk
You can on ly shift into Park when the vehi cle is
stationary¢ &.
Drivi ng
To shift in and out of the P selector lever posi­
tion, press the inter lock button in the selector
lever
while pressing the brake pedal.
R- Reverse
Only s hift into reverse gear when the vehicle is
stationary and the engine is runn ing at id le
speed¢ &.
To se lect the R selector leve r pos ition, press the
in terlock button
while press ing the brake pedal.
T he back-up lights sw itch on in the R pos ition if
the ignition is switched on.
N -Neutral
The t ransmission is in idle in th is posit ion.
D IS -Norm al position fo r driving forward
In the D/S se lector lever position, the transmis­
s ion can be operated either in the normal D mode
or in the S sport mode . To select the S sport
mode, pull the selector lever back briefly . Pulling
the leve r back aga in will selec t the normal D
mode. The selected d riving mode is shown in the
Infotainment display.
In the
n ormal mode "D", the transm ission auto­
matically selects the suitable gear ratio.
It de­
pends on engine load, vehicle speed and driving
sty le.
Select the
s p o rt mod e "S" for sporty driving . The
vehicle makes full use of the eng ine 's powe r.
Shifting may become noticeable whe n accelerat­
i ng.
To move from selector lever pos ition
"N" to "D",
you m ust press the brake peda l and the vehicle
must be traveling less than 1 mph (2 km/h) or be
stationary¢ &.
A WARNING
Read and fo llow all WARNI NGS .
- The vehicle can roll even if the ignit ion is
switched off .
- Never se lect R or P whi le driving, because
this increases the risk of an accident .
- Power is still transmitted to the wheels
when the engine is runn ing at idle. To pre­
vent the vehicle from "creeping", yo u must

wheel will vibrate lightly. In order for this warn­
ing vibration to occur, it must first be switched
on in the Infotainment system. Active lane assist
is ready for operation when the lane marker line
is detected on a t least one side of the vehicle.
The system is design ed for driving on express­
ways and highways and so it only activates at
speeds above approximately 40 mph (65 km/h)
(depending on the market).
Applies to vehicles with side assist* : if you acti­
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there will be noticeable corrective steer ­
in g shortly before you leave the lane . This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist *: the sys­
tem does not warn when it is ready if you activate
the turn signal before crossing the lane marker line. In this case , it assumes that you are chang­
ing lanes intentionally .
A WARNING
- The system warns the driver that the vehicle
is leaving the lane using corrective steer ing.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can assist the driver in keeping
the vehicle in the lane, but it does not drive
by itself. Always keep your hands on the
steering wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
-There may be cases where the camera does
not recognize all lane marker lines . Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected .
-Other road structures or objects could possi­
bly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur .
8 1l The corrective stee rin g func tion is not avail able in all mar­,..._
~ ket s.
Assistance systems
-The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by dirt on the window . This can
result in active lane assist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situations where visibility is low,
the vehicle may switch internally from "ear­
ly " to "late" steering correction
l).
-Under certain conditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
potential for hydroplaning. Using active lane
assist under these conditions may increase
the risk of a crash.

not switch off, but it is "not ready" to provide a
warning . The system can he lp you keep the veh i­
cle in the lane. However, you are responsible for
driving the vehicle and must steer it yourself .
A WARNING
Note that messages may be delayed or not
displayed on vehicles with accessor ies mount­
ed on the steer ing whee l, such as a stee ring
wheel sp inner knob. Always keep you r hands
on t he steering whee l.

_& WARNING
-Always look for traff ic and check the area
around your vehicle by looking at it direct ly
as well. The parking system cannot replace
the driver's attention . The driver is always
responsib le when entering or leaving a park­
ing space and during similar maneuvers.
- Please note that some surfaces, such as
clothing, are not detected by the system.
-
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals.
- The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park ­
i ng system may be impa ired as a result .

thorized Audi Service Facility .
Parking systems
-Only use the rearview camera to assist you if
it shows a good, clear picture. For example,
the image may be affected by the sun shin­
ing into the lens, dirt on the lens, or if there
is a malfunction.
- Use the rearview camera only if the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera.
- The camera lens enlarges and distorts the
field of vision. The object appears both al­
tered and inaccurate on the screen.
- In certain situations, people or objects in
the display appear closer or farther away:
- For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck. Do not use the orientation lines in this case.
- If driven from a level surface onto an in­ cline, or a downward slope .
- If driven toward protruding objects.
- If the vehicle is carrying too much load in
the rear.

snow and ice. Always read and follow safety pre­
cautions
¢ .&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c::> page 259, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c::> page 251, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
,& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- 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 be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases 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 whee l drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.

Airbag syste m
the system inspected immediately by your
authorized Aud i dealer. It is possible that
the a irbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restra int, or in a rearward-facing child
safety seat, or in a forward-facing child re­
st raint that has not been p roperly installed
w ill be seriously injured and can be killed.
- If you must install a rearward-fac ing child
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN­
GER AIR BAG
OFF ,;; light does not appear
and stay on, have the airbag system inspect­
ed by your Audi dealer.
- If, in exceptiona l circumstances, you must
install a forward-facing chi ld restraint on
the front passenger seat, always move the
seat into its rearmost pos ition in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest
must be adjusted to an upright posit ion .
Make sure that the PASSENGER AIR BAG
OFF ,;; light comes on and stays on a ll the
t ime whenever the ignition is switched on.
A WARNING
If the PASSENGER AIR BAG OFF ~; ligh t does
not go o ut when an adult is s itting on the
front passenger seat after taking the steps described above, have the airbag system in­
spected by your Audi dealer before transport­
ing anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side w ill be turned off, and the
PA SSENGER
AIR BAG
OFF ~; light will stay on.
Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Insta lling, remov-
208
ing, servicing or repair ing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from work ing properly
i n a coll is ion.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, servicing and repair proce­
du res can increase the risk of personal in jury
and death by p reventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
s trumen t panel or modify them in any way.
- Never attach any objects s uch as c up ho lde rs

- For cleaning the horn p ad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water . Solvents or cleaners
could damage the airbag cover or change
the stiffness o r strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, ad just, or change any parts o f
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular te lephones and CB radios, etc.)
m ust be performed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­

- Never modify the front bumper or pa rts of
the vehicle body.
- Always make sure that the side a irbag can

Child sa fety
Advanced front airbag system and children
Your veh icle is equipped w ith a front "Advanced
A irbag System" in comp liance w it h United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your veh icle has
been certified to meet the " low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the a irbag inflates. In addit ion, the
system has been certified to comply w ith the
" su ppress io n" req uirements of the Safety S tand­
ard, to tu rn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven tho ugh yo ur vehicle is equipped with an
Ad a
vanced Airbag system, a chi ld should a lways ride
in the seat proper ly restrained for its age and
size. The airbag on the passenger side makes the
front seat a potentially dangerous p lace for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dange rous place for a n infant or a
larger child in a rearward-fac ing seat.
The vehicle's Advanced Airbag System has a ca­
pac itive passenger detect ion system in the front
passenger seat cush ion that ca n detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on t his seat .
The capac it ive passenger detect ion system regis ­
ters the changes that result in an electr ical field
when a c hild, a child restra int, and a baby blanket
a re on the front passenge r seat. The change in
t he meas ured capacitance due to t he p resence o f
a child, a chi ld restraint, and a baby b lanket on
the front passenger seat is re lated to the chi ld
restraint system resting on the seat . The meas ­
ured capacitance of a ch ild restraint system var-
218
ies depending on the type of system and specific
make and mode l.
The elect rical capac ita nce of the va rious types,
makes, and models of child restra in ts speci fied
by the U.S . National Highway Tra ffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
c hi ld restraint is used on the front passenger
seat w it h a typical 1 year-old infant, t he Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detect ion
system wi th the data stored in the e lec tronic co n­
tro l unit .
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
factu rer for use w ith an airbag . If in exceptional
c ir cumstances you m ust use it on the front pas­
senger seat, ca refully read all of the information
o n chi ld safety and Advanced Airbags and heed
a ll of th e app licab le WARNINGS . Make certain
that the chi ld and chi ld restraint are correctly
recognized by the capacitive passenger detection
system in the front passenger seat, that the front passenger a irbag is turned off, and that the air­
bag status is always correct ly signa led by the
PASSENGER AIR BAG OFF ~; light.
Many types and models of child restra ints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production . Ch ild rest rai nts are not standa rdized .
Child res tra ints of the same type typically have
d iffe rent weights and sizes and diffe re nt "foot ­
pr ints", the size and shape o f th e bo ttom of the
ch ild restraint that sits on the seat, w hen they
are installed on a vehicle seat . These differences
make it virtua lly impossib le to certify comp liance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .
