System limitations
General information
App lies to vehicles: with adaptive cruise control
Some driving situations which affect the func­
tion of the radar sensor are described below.
When driving, the adaptive cru ise control is
governed by physical and system-specified
limits. Also, under certain circumstances, the
ACC system may react unexpectedly or late
from the driver's po int of view. Therefore, al­
ways be attentive and intervene, if necessary:
- when driving around curves¢
page 112
-when vehicles in front are not in line with
your vehicle ¢
page 112
-when other vehicles are changing lanes
r:=>page 113
-when other veh icles are difficult to detect
r:=> page 113.
A WARNING
The radar sensor's vision can be reduced by
rain, snow and heavy spray. This can result
in vehicles driving ahead being inade­
quately d etected or, in some c ircumstan­
ces, not detected at a ll.
If ne cess ary, take
a ction yourself!
When driving around curves
Applies to vehicles: with adaptive cruise control
Fig. 122 Vehicle entering a cu rve
Fig. 123 Ve hicle leav ing a cu rve
Entering a curve
When enter ing a curve, the adaptive cruise
control may react to a vehicle in the next lane
and apply the brakes in yo ur vehicle
r:=> fig. 122. The braking action can be overrid­
den by depressing the accelera tor pedal.
Leaving a curv e
At the exit from very long curves the pred ic­
t ive lane reading can cause the adaptive cruise
control to react to another vehicle in the next
lane and apply the b rakes in your vehicle
r=>fig . 123. The braking action can be over rid­
den by depressi ng the acce le ra tor pedal.
, Vehicles offset to one side
Applies to vehicles: with adaptive cruise control
Fig. 124 Ve hicle traveling a head outside the detect ion
range of the radar sensor
Vehicles trave ling ahead and to one s ide can ­
not be detected by the adaptive cru ise contro l
unt il they are within the detect ion range of
the sensor.

114 Adaptive cruise control
The Audi braking guard is active from a speed
of approx. 20 mph (30 km/h) and works with­in the system limits¢
page 112 even when
the adaptive cruise contro l is deactivated.
A radar sensor is bui lt into the front of the ve ­
hicle
¢ page 102, fig. 110. The system is in­
tended to measure the distance to reflective
surfaces. If a measurement is not possible,
the system does not respond .
When the measurement has taken p lace, the
system can assess a hazardous situation,
when a vehicle ahead suddenly brakes or when
your own vehicle is driving at high speed to­
wards a much slower vehicle ahead . As soon
as the system assumes that a possible colli­
sion with the vehicle ahead can on ly be avo id­
ed by immediate all-out braking or by an
avoiding maneuver, a warning appears.
The system has a pre-set response time to be
able to warn in good t ime . This system re­
sponse time is automat ically reduced if you
accelerate actively, for example to join a high­
way. Braking, transverse acceleration and the
steering angle can lead to a reduced system
response time . The warning is deactivated if
you begin to overtake with fu ll acce leration.
The system draws your attention to two differ­
ent hazardous situations:
Distance
The distance warn ing is issued in the event of
inadequate distance to the veh icle ahead ape­
riod of more than 5 seconds . If the distance is
l ess than 30 feet (9 meters) at 50 mph
(80 km/h) , for example, an optical display is
faded in on the instrument cluster¢
fig. 129.
If the vehicle ahead brakes sharply, a collision
cannot be avoided , even in the case of an im­
mediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower veh icle ahead in your
la ne, or if the vehicle ahead brakes sharply,
the Audi braking guard ca lculates the point
from which a collision can only be avoided by all-out braking or
by an avoiding maneuver. If
a warning does sound, a possib le collision
with the vehicle in front can be avoided
through an evas ive maneuver or by braking .
T he warning is given in two stages:
-Pre-warning: An optical display appears in
the instrument cluster and a warning tone
so unds.
- Acute warning: If you do not respond to the
pre-warn ing, the second stage , the acute
warning, is issued . A brake jolt reminds you
to concentrate on the road again.
Under heavy brea king, brake assist
¢
page 209 also helps you obtain max imum
braking efficiency.
.&_ WARNING ~
Always pay attention to traffic, even when
the Audi braking guard is switched on. You
are a lways responsible for your speed and
the distance between your vehicle and oth·
er vehicles.
-Always keep the lega lly stipulated safety
d istance between your vehicle and the
veh icle ahead • danger of accident!
- The Audi braking guard does not respond
outside the system limits, for example if
you approach a stationary obstacle (end
of a traff ic jam or breakdown vehicle).
- Please observe that the Audi braking
guard is subject to restrictions in narrow
bends due to the field of vision of the ra­
dar senso r. T his may possibly lead to ob­
stacles not being detected.
- The radar sensor's
vision can be reduced
by rain, snow and heavy spray. This can
resu lt in vehicles driving ahead being in­
adequately detected or, in some circum­
stances, not detected at all. Always
watch where yo u are driving .
- Reflecting objects such as e.g . crash bar ­
riers or the entrance to a tunne l may im­
pair the function of the radar sensor .

Interlock button
The lock button on the selector lever prevents
the lever from being accidentally shifted into
certain positions. Pressing this button deacti­
vates the selector lever lock. Depending on
the direction of the shift, the selector lever
locks at different positions. The positions are
highlighted in the illustration
c::> fig . 145.
Ignition key safety interlock
The key cannot be removed from the ignition
unless the selector lever is in the
P park posi­
tion. When the ignition key is removed, the
se lec tor Lever will be locked in the
P position.
Kick-down
App lies to vehicles: with automatic transmission
The kick-down feature allows the vehicle to
generate maximum acceleration .
When you press the accelerator pedal beyond
the resistance point that is reached at full
throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine
RPM . The engine RPM will be controlled to
produce maximum vehicle acceleration as
long as you continue to press the accelerator
pedal beyond this resistance point.
.&, WARNING
Be careful when using the kick-down fea­
ture on slippery roads. Rapid acceleration
may cause the vehicle to skid .
Dynamic shift program (DSP)
Applies to vehicles: wit h automatic transmission
The automatic transmission is electronically
controlled.

The transmission is self adapting and will au­
tomatically
select the best sh ift program suit­
ed to the driving conditions and driving style .
The transmission will select one of the
econo­
my
programs when you drive at a steady
speed or a gradually changing speed w ithout
heavy acceleration. This achieves optimum ..,.

130 Transmi ssion
fuel efficiency, with ear ly upshifting and
de layed downshifting.
The transmission will a utomat ica lly select the
s port y shift prog rams when you drive at high­
e r speeds, or w ith heavy acceleration and fre­
quent ly changing speeds. Upshifts are de layed
to make full use of eng ine power. Downsh ift­
ing takes p lace at h igher engine speeds than
in the economy programs .
The selection of the most suitab le shift pro­
gram is a cont inuous, 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 orig inal program is se lected acco rding to
your d riving s tyle.
A n addit ional shift program allows the auto ­
mat ic transm iss ion to select the proper gear
for uphill and downhill gradients .
This keeps the transmission from shifting up
a nd down unnecessar ily on hills . The trans ­
miss ion will shift down to a lowe r gear when
the dr iver presses the brake pedal on a down­
hill grad ient. This makes use of t he b raking ef­
fe ct of the eng ine wi thout the need to shift
down manua lly. Manual shift program
Applies to
vehicles: with automatic transmission
Using the manual shift program you can
manually select gears .
