Ap plies to vehicle s: with side assist
General information
Side assist has lim its and cannot detect vehic les under all road and
weather conditions. P lease remember system limitations and
never
rely on the system, especially when:
• driving through curves=>
page 763,
• lanes are of different widths=> page 163. •
Applie s to vehicles: with side ass ist
When dr iving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve , it is possible that side assist may
register a vehicle two lanes
over, and the signal on the outside
m irror will ligh t up .•

Side assist's detection area is designed to cover lanes of standard
width to the le ft and right o f your trave l lane, depending on whethe r
you drive in the center of your lane or c loser to the edge.
If you drive in narrow lanes, side assist's detection area may also
inc lude other lanes -especially if you tend to dr ive on the edge o f
your lane=> fig . 184. Under these conditions, vehicles can also be
de tected tha t are two lanes away, and s ide assist then could switch
between the informational and warning stage signa ls.
When d riving in
very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •

fig . 194 t o activate the A udi pa rking system m anually .
Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound . The indicator lig ht in
the switch lights up.
D ea ctivation
If you drive forwards faster tha n approx. 6 mph (10 km/h),
or
- if you switch the ign ition off, the entire acoustic parking
assist is automatically deactivated, or
- you can press the sw itch
P111! i n the center console
=> page 173, fig. 194 to deact ivate the Audi parking
system. The indicator light in the switch goes out.
You have to turn on the acoustic parking assist m anuall y if you wish
to park the vehicle forwards or if you w ish to approach an obstacle
forwards and want a distance warning .

5 .2 ft (1.60 ml
Distance warning is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MMI => page
183.
Mute
In the case of vehic les with automa tic transmission, an acoustic
distance warning is discontinued when the transmission selector l
ever is moved to the P position. However, the system remains
active . As soo n as the selector lever is moved from the
P posi tion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes .
Dri ving fo rward/ba ckvv ard
Distance warning when driving forward/backward is based o n
detection of an obstacle in the range of the parking assist . As the
distance dec reases, the time interval between the audible tones
becomes shorter.
When the distance is less than approx . 1 ft (0.30 m), the tone
becomes continuous. At this point you shou ld s top backing up or
driving forward .
If the distance to an obstac le remains the same, the vo lume of the
distance warning is gradually reduced after about
4 seconds (does
not app ly to the zone for the cont inuous tone). If you sta rt to
approach the detected obstacle again, the distance warning will
sound at the normal volume again .
P a rk ing
When you selec t ano ther gear when parki ng (e .g . reverse/forward),
the warning tones are temporarily suppressed, but the visual display remains on the MMI display . If you start approaching a
detected obstacle again, the distance warning wi ll sound at the
normal vo lume again .
Visual disp lay
T he segments on the MMI display indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstacles in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer the
segments approach the vehic le => page
173 , fig. 195. When the
segment before last is disp layed, the veh icle has reached the colli­
sion zone. At this point you should stop backing up or driving
forward =>

Chassis Controls
Four different driving modes can be set by the driver.
The automatic control processes are speed -and time -dependent.
For example, it is not possib le to raise the suspension to the lift
mode above certain speeds .
When a speed of about 75 mph ( 120 km/h) is exceeded for more than
30 seconds, the vehicle is automatically lowered approximately 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road holding is optim ized as a result of the lower
center of gravity and fue l consumption is reduced as a result of
reduced wind resistance .

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road ~& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instructions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents. For your protection and that of your passengers, always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts . Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts. The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your Audi has a total of five seating positions: two in the front and
three in the rear . Vehicles with power individual rear seats* have
seating for four: two in the front and two in the rear. Each seating
position has a safety belt.
