The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 133 even when
the adaptive cruise control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 122,
fig. 112. The system is intended to measure the distance to reflective
surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has taken place, the system can assess a
hazardous situation, when a vehicle ahead suddenly brakes or when
your own vehicle is dr iving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli­
sion w ith the vehicle ahead can only be avoided by immediate all-out
braking or by an avoiding maneuver, a warning appears .
Th e system has a pre-set response time to be able to warn in good
time. This system response time is automatically reduced if you accel­
erate actively, for example to join a highway. 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 full accelerat ion.
The system draws your attention to two different hazardous situa ­
tions:
Distance
Th e distance wa rning is issued in the event of inadequate distance to
the vehicle ahead a period of more than S seconds. If the distance is
less than 30 feet (9 meters) at SO mph (80 km/h), for example, an
optical display is faded in on the instrument cluster=>
page 135,
fig. 131.
If the vehicle ahead brakes sharply, a collision cannot be avoided,
even in the case of an immediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your lane, or if the vehicle
ahead brakes sha rply, the Audi braking guard calculates the point from which a collision can only be avoided by all-out brak
ing or by an
avoiding maneuver. If a warning does sound, a possible collision with
the vehicle in front can be avoided through an evasive maneuver or by
braking.
Th e warn ing is given in two stages:
• Pre-warning: An optical display appears in the instrument cluster
and a warning tone sounds.
• Acute warning: If you do not respond to the pre-warning, the
second stage, the acute warning, is issued. A brake jolt reminds you
to concentrate on the road again.
Under heavy breaking, brake assist =>
page 241 also helps you obtain
maximum braking effic ien cy.
& WARNING
Always pay attention to traffic, even when the Audi braking guard
is switched on. You are always resp onsible for
your speed and the
distance between your vehicle and other vehicles.
• Always keep the legally stipulated safety distance between
your vehicle and the vehicle 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
traffic jam or breakdown vehicle).
• Please observe that the Audi braking guard is subject to restric­
tions in narrow bends due to the field of vision of the radar sensor.
This may possibly lead to obstacles not being detected.
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray . This can result in vehicles driving ahead being inade­
quately detected or, in some circumstances, not detected at all.
Always watch where you are driving.
• Reflecting objects such as e.g. crash barriers or the entrance to
a tunnel may impair the function of the radar sensor.•

Side ass ist uses radar sensors (not vi sible on outside)=> fig. 132 to
help the driver check blind spots , and see what is happen ing in traffic
behind the vehicle=>
page 139, fig. 135.
Signal lights are bu ilt into both outside mirrors
(D => fig . 133 . The
signal ligh t on the left ou tside mirror assists when moving over in to the
left lane and the signal light on the right outs ide mirror assists
when moving over into the right lane.
T he sig nal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle should be taken into acco unt if you were to change lanes . This is called the
inf ormational stage signal =>
page 140. The informationa l stage
signal is designed so that you not ice it only when you are looking in
the o utside m irror.
When you activate the turn s ignal and side assist detects a vehicle in
a notable locat io n, the co rrespo nd ing s ignal on the ou tside m irror
flashes briefly and brightly several times. This is the alert stage
s ignal =>

& WARNING
• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicle s
in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius le ss than 328 feet or 100 m).
• Side assist is no replacement for the driver's full attention. The
driver alone is respon sible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

The detection~ page 139, fig. 135 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle , and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes
are
not covered by the radar sensors .
rn Tips
Side assist does not measure actual lane width. The system assumes
a fixed lane width. Detection in the left and right lanes is based on
this assumed lane width. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~
page 144. •
Applie s to vehic les: w ith s ide a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes , a signa l light appears on the respective mirror .
The signal can light up if you are passed by a vehicle or if you are
passing another vehicle .
If you pass another vehicle slowly (difference in speed less than 9
mph, or 15 km/h), the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist. When the
difference in speed is greater, the signal light will not come on. •
Appli es to vehicles : with si de assist
Informational and alert stage signals
Side ass ist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropr iate signal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes.
Informational stage signal
As long as you have not activated the turn signal, s ide assist informs
you of detected vehicles that are reg istered as being in a notable loca ­
tion if you were to change lanes . Whenever the detected vehicle's
difference in speed and distance is registered by side assist as
notable , the signal light on the respective mirror produces muted
illumination.
Th e brightness of the informat ional stage signal is designed not to be
as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. When
you look in the outs ide mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you act ivate the turn s ignal , and side assist has detected a
vehicle in a notable location on that particular side , the signal light on
this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so that
you can safely complete the lane change~
& in "Safety tips" on
page 145.
rn Tips
The brightness of the signa l light on the outside mirrors can be
adjusted with the MMI*
