• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control. • Adjust the driver 's seat or steering wheel so that th ere is a
minimum of 10 inches (25 cm ) between your chest and the
steering wheel~
page 188, fig. 198. If you cannot maintain this
m inimum distance, the airbag system cannot protect you prop ­
erly.
• If physical l imitations p revent you from sitting 10 inches (25

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. •

position and have the airbag system inspected by your Audi
deal er.
• A tight tether or othe r strap on a rearward-facing child
restraint attached to the front passenger seat can put too much
pressure on the weight-sensing mat in the seat and register more
weight than i s actually on the seat. The heav ier weight registered
can make the system work as though an adult were on the seat
and deploy the Advanced Airbag when it must be suppressed
causing serious or even fatal injury to the child .
• If, in ex ceptional circumstances, you must install a forward·
facing child restraint on the front passenger seat, always move
the seat into i ts rearmo st po sition in the seat's fore and aft adjust ·
ment range, as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light do es not go out when an
adult is sitting on the front passenger seat after taking the steps
de scribed above, make sure the adult i s properly seated and
restrained at one of the rear seating positions.
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .

Repair, care and disposal of the airbags
Parts o f the a irbag system are installed at many different p laces on
your Audi. Install ing, remov ing, servic ing or repa iring a part in an
area of the ve hicle can damage a part of an airbag system and preve nt
t ha t system from working pro perl y in a coll is ion.
T here are some important thi ngs you have to know to make sure that
the effectiveness of the system will not be impa ired and that
discarded components do no t cause injury or poll ute the enviro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover, obstruct , or change the steering wheel horn pad or
airbag cover or the instrument panel or modify them in any way.
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag unit s.
• For cleaning the horn pad or instrument panel, use only a soft,
dry cloth or one moistened with plain water. Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop·
erly .
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip·
ment , cellular telephones and CB radios, etc .) must be performed
by a qualified technician who ha s the training and special equip ·
ment necessary .
• For any work on the airbag system, we strongly re commend
that you see your autho rized Audi dealer o r qualified workshop.
• Never modify the front bumper or parts of the vehicle body.

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e coolant temperature gauge~ page 10 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
_f_ , pull off the road, stop and let the engine idle for
about two m inutes to prevent heat build-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi.•
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
Maintain a greater distance between your 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 that you cannot accelerate as fast as you normally would because of the added load . Make sure you have
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 361. •
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:
- Apply the foot brake.
- Have someone p lace chocks under both the vehicle and the
trailer wheels . ._
