Audi active Lane assist
Description
Applies to: veh icles w ith Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane ma rker lines withi n the l imits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and it appears likely that you will leave the lane, the
system will warn you w ith corrective stee ring .
You can override this steering at any time . If you
112
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc­
cur, it must first be switched on in the Infotain­
ment system. Active lane ass ist is ready for oper­
a tion when the lane marker line is detected on at
least one side of the vehicle .
T he system is des igned for driving on express­
ways and highways and therefore on ly activates
a t speeds above approximately 40 mph (65 km/
h) .
Applies to vehicles with s ide ass ist*: if you acti­
vate a turn signa l when active lane assist is ready
a nd it classifies a lane change as critical bec ause
of veh icles traveling a longside you or approach ­
i ng you, there will be noticeable corrective steer­
i ng 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 act ivate
the turn signal before crossing the lane marker
lin e. In this case, it assumes that you are chang­
in g lanes intent ionally.
Applies to vehicles with adaptive cruise contro l*:
there is no corrective steer ing or warnings if the
system recognizes a distinct passing maneuver.
If the conditions are met, congestion assist
switches on at speeds under approximately
40 mph (65 km/h)
¢page 104.
_& WARNING
-The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways 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.

Assist
Information stage
As long as you do not activate the turn signal,
side assist
informs you of the vehicles that are
detected and classified as critical. The display in
the mirror turns on, but is dim .
The display remains dim in the information stage
so that your view toward the front is not distur­
bed.
Warning stage
I f the display in a mirror blinks br ight ly when you
ac tivate a turn signal, side assist is
warning you
about detected ve hicles that it has classified as
critical. If this happens, check traffic by glancing
in the exterior mirror and over your shoulder
q &.
in General information on page 117.
Appl ies to vehi cles w ith active lane ass ist*: the
disp lay in the mirror can also blink if you have not
activated a turn signal: if you are approaching a
detected lane marker line and it appears you will
be leaving the lane, side assist will warn you
about detected vehicles that it has classified as
cr itical.

mation in the sections that follow and be sure to
heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­ ting s ideways or out of position in any way,
your risk of injury is much h igher.
- You will also receive serious injuries and could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag
r:::;, page 253 .
A WARNING
A child in a rearward-facing chi ld safety seat
installed on the front passenge r seat w ill be
ser iously injured and can be killed i f the front
airbag inflates -even w ith an Advanced Ai rbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to tu rn off the front
airbag when a rearwa rd -facing child re ­
straint has been insta lled on the front pas­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the useful life of your vehicle .
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest , door,
o r roof .
- Always install rearward -facing ch ild re ­
straints on the rear seat .
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be­
cause of exceptiona l circumstances and the
PASSENGER AIR BAG OFF~; light does not
c ome on and stay on, immed iate ly install
the rear-fac ing ch ild safety seat in a rear
seating position and have the airbag system
inspected by your authorized Audi dea ler.

A WARNING ,_
If, in exceptional circumstances, you must in­
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been des igned and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forwa rd-facing child restraint
up against or very nea r the instrument pan­
el.
- Always move the front passenge r seat to
the highest posit ion in the up and down ad­
justmen t range and move it back to the
rearmost posit io n in the seat's fo re and aft
adjustment range, as far away from the a ir ­
bag as poss ible, before install ing the for­
ward-facing chi ld restraint.
- Always make sure that the safety be lt upper
anchorage is behind the chi ld rest raint and
not next to o r in front of the c hild restraint
so that the safety be lt will be p roper ly posi­
tioned.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
no t, or to signal that it is occupied by some­
one who is heavier than the person ac tually
si tting on the sea t. T he presence of addi­
tional objects could cause the passenger
front airbag to be turned on when it should
be
off, or could cause the airbag to work in a
way that is d ifferent from the way it wou ld
have worked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OFF ~;
light comes on and stays on all the
time whenever the ign it ion is switched on.
Advanced Airbag System components
T he front passenger seat in your veh icle has a lot
of ve ry important parts of the Advanced A irbag

Airbag system
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats
on the rear seat.
- If you must install a rearward -facing child
safety seat on the front passenger seat be­ cause of exceptional circumstances and the
PASSENGER AIR BAG OFF,;, light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your authorized Audi dealer .
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer ­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself . These objects
could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger's seat to
transport objects. Items can also move into
264
the area of the side airbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front
passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat .
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that the seat is occupied by a person when it is
not , or to signal that it is occupied by some ­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat .
A WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a
history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy , wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches. ..,_

-If the residue should get into your eyes,
flush them with water.

When t he mal funct io n ind icator is ill umin ated,
the system may not be ab le to detec t or signal
l ow tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, incl uding the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensu re
that the replacement or alte rnate ti res and
wheels a llow the TPMS to con tinue to func tion
p roperly.

or if there is a system mo/function.
Using the ABS sensors, the tire pressure mo nitor ­
