Audi lane assist
Lane assist
Applies to vehic les : w ith lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver . If lane assist
de tects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indicator light /: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high­
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane . The
driver is always responsible for keeping the vehicle in the lane .
• The camera is not able to detect all lane boundary lines and in
some cases might also detect lane structures or objects as
boundary lines . This can lead to incorrect warnings or warnings
that fail to go off at all.
• The camera's visibility can be impaired by vehicles ahead of
you , for instance, or by rain, snow, heavy spray or light shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •

detected lane boundary lines. -.,

Audi lane assist -
----------------
, Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warning. This can be due to the
following:
• There are no boundary lines, or there is only one boundary line
present .
• The boundary lines are not detected (e.g. due to snow, dirt, wet
conditions or light shining into the camera lens).
• More than two boundary lines (such as at construction sites) are
located in the vehicle's lane.
• The vehicle's speed is below the speed needed to activate it,
which is about
40 mph (65 km/h).
• The lane is narrower than about
8 ft. (2.5 ml, or wider than about
16 ft. (5 ml.
• The curve is too sharp.
Notes on the instrument cluster display
When the lane assist turns off automatically, the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lane assist not available: Currently no sensor vision
This message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• The exterior side of the camera viewing window=>
page 150,
fig. 148 is covered with dirt or ice. Clean this part of the windshield.
• The camera viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• The system was unable to detect boundary lines over an
extended period of time due to road conditions (such as snow­
covered lanes). Do not turn lane assist on again until the lines can
be more easily detected.
Audi lane assist not available
Controls and equip ­
ment A temporary malfunction is preventing
lane assist from operating .
Try turning on lane assist again at a later time.
Audi lane assist: system fault
The system should be checked by an authorized Audi dealer or other qualified workshop.
[ i] Tips
• Make sure that the camera viewing window=> page 150, fig. 148
is not covered by stickers or similar objects .
• Always keep the camera viewing window clean. This can usually
be done by operating the windshield wipers. •

Setting the warning time
Early: This setting warns the driver before a wheel touches the
detected lane boundary line. The warning depends on the vehicle's
angle as it approaches the boundary line . If you approach a
boundary line gradually, the warning w ill occur earlier. If you
approach the boundary line at a very sharp ang le, the warning will
occur just before a wheel touches the line.
Adaptive : In this setting, the warning time adjusts to the character ­
istics of the road and the vehic le speed. The warning occurs later for
curves and occurs earlier for straight stretches of road . The warning
occurs later on narrow roads than on wide roads.
Late: This setting warns the driver when a whee l drives over the
detected lane boundary line .
Setting the steering wheel vibration
When adjusting the steering wheel vibration, the steering wheel
vibrates so that you can check the intensity you have set.
[ i ] Tips
• When making the adjustment, lane assist is not activated. The
steering wheel vibrates briefly only to assist you in changing the
setting .
• Your settings are automatically stored and assigned to the
remote control key being used.•

& WARNING
• Unintended vehicle movement can cause serious injury .
- When the selector lever is in a driving po sition , the vehicle
m ay creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move ,
be cause power i s tran smitted to the wheels as soon as a
driving position is engaged .
- Do not accelerate wh ile se le cting a driving position . At th is
t ime the engine must be at idle speed so that undue stre ss is
not pla ced on the clut che s in the tr ansmission .
- Remember : - even when stopped briefly with the automatic
tr ansmission in "D ", "S " or "R ", engine po wer i s bei ng tran s­
mitted to the whe els. Y our vehicle could "c reep " forward or
ba ckward. When stopped , keep the brake pedal fully depre ssed
and u se the parking brake if nece ssary to keep the vehicle from
rolling .
• If the selector lever is unintentionally moved into N while you
are driving , take yo ur foot off the a ccelerator pedal and wait fo r
the engine to return to id le speed before selecting a driving posi ­
t ion .
• Never shift into "R " or "P " when the vehicle i s in motion .
• Never get out of the driver 's seat when the engine is runnin g.
• If you must get out of the veh icle, move the selector le ver
se curely into the P position and appl y the park ing brake firmly .
• If the engine must remain running , ne ver have any dr iving po si­
tion engaged when che cking under the hood . Make sure the

The transmission wil l se lect one of the

upshifting and delayed downshifting.
The trans missi on will au tomat ica lly select the

when you drive at higher speeds, or with heavy acce leration and
frequen tly cha nging speeds . Upshifts ar e delayed t o make full use

The selection of the most suitable shift program is a continuous,
automatic process. The driver can also make the transmission
switch to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g. for quickly passing another vehicle.
You do not need to press the gas pedal into the kick -down range.
After the transmission has upshifted, the original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients .
This keeps the transmission from shifting up and down unneces ­
sarily on hills. The transmission will shift down to a lower gear when
the driver presses the brake pedal on a downhill gradient. This
makes use of the braking effect of the engine without the need to
shift down manually .•

When accelerating, the transmission will automatica lly shift into
gears 1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you apply a light throttle when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear .
If you take your foot off the a ccelerator peda l when driving down a
steep incline, tiptronic® wi ll downshift from the selected gear into
the next lower gear until it reaches 1st gear , based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the throttle again . .,_
