m inimum distance, the airbag system cannot protect you prop ­
erly.
• If physical l imitations p revent you from sitting 10 inches (25
c m ) or more from the steering wheel, che ck with your authorized
Audi dealer to see if adapt ive equipment is a vailable.
• If the steering wheel is aligned with your face, the supp le­
mental dri ver 's ai rbag cannot prov ide as much protection in an

& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats up because of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immediate ly after hard or extended driving .
Keep the engine running for approximately two minutes to prevent
excessive heat build-up. •

Aud i Lane assist
Lane assist
Applies to veh icles : 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 detects
boundary lines on both sides o f the veh icle's lane, the system enters
act ive standby mode, which is indicated by t he gree n 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 sinc e th e system allows for in tention al lane changes.
The system is designed for driving on freeways and expanded high­
ways and th us 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. •

Not read y: The yellow indicator light shows that the system is
turned on but unable to send a warning. T his can be due to the
following:
• T here 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 const ruct ion sites) are
located in the vehicle's lane .
• T he veh icle's speed is below the speed needed to ac tivate it, which
is about 40 mph (65 km/h) .
• T he lane is narrowe r than about 8
ft . (2.5 m), or wider than about
16 ft. (5 m).
• Th e curve is too sharp.
Note s on the in strum ent clust er displa y
When the lane assist turns off automat ica lly, the instrument cluster
indicator goes out and one of the fo llowing messages appears on the
display :
Aud i lane ass is t not av ailable: Cur rentl y n o sens or v ision
T his message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• T he exte rior side of the came ra viewing window =>
page 142,
fig. 157 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog d isappears before turning lane assist on
again.
• T he system was unable to detect bo undary lines over an extended
period of time due to road co nd it ions (such as snow-cove red lanes) .
Do not turn lane assist on aga in until the lines can be more easily
detected .
