Applies to vehicles: with side assistArea covered by the radar sensorsThe area covered by the radar sensors ⇒fig. 166 consists of:•
The rearward approach zone (light green area: up to about 50
metres) and
•
Blind spots (dark green area) .
The radar sensors monitor the lanes immediately to the left and
right of your vehicle. Other lanes are not covered by the sensors.Note
The side assist system is programmed for lanes of a fixed width, and
is not able to measure differing lane widths. It monitors a zone
equivalent to one normal lane width on either side. If the lanes are
narrower than this, or if vehicles are not travelling in the centre of
the lanes, the system may register vehicles that are not in fact trav-
elling in an adjacent lane ⇒page 156 .Applies to vehicles: with side assistHow the system worksWhen other vehicles are detected, the side assist system registers
their distance and how fast they are approaching. The warning lamp on the relevant exterior mirror will light up whenever the side assist
calculates that the distance and the speed differential of
approaching vehicles would be critical in the event of a lane change.
The warning lamp may light up when you are being overtaken and
when you are overtaking another vehicle.
If you are overtaking slowly, with a speed differential of less than
15 km/h, the warning lamp will light up as soon as the other vehicle
enters your blind spot and is detected by the sensors. If you are
overtaking with a speed differential which is greater than this the
lamp will not give a warning.
Applies to vehicles: with side assistInformation mode and warning modeThe side assist has two modes of operation•
The information mode and
•
The warning mode
The side assist will respond in the appropriate mode, depending on
whether or not you operate the turn signal to indicate an intended
lane change.
Information mode
As long as you do not operate the turn signal, the side assist will
merely inform you of the presence of vehicles that it has detected
and judges to be critical in the event of a lane change. The warning
lamp on the relevant exterior mirror will light up with low intensity
whenever the side assist calculates that the distance and the speed
differential of an approaching vehicle are critical.
The intensity of the warning lamp in this information mode is delib-
erately kept relatively low, so that it does not distract you while you
are looking at the road in front and do not intend to change to a
different lane. The information mode is clearly visible when you look
in the exterior mirror.

152Warning mode
If you operate the turn signal when the side assist has detected a
vehicle on that side that it judges to be critical in the event of a lane
change, the warning lamp on the relevant exterior mirror will flash
brightly several times. This is the warning mode: if the lamp flashes
brightly it warns you th at you should check the situation again in the
mirror and by looking back over your shoulder ⇒ in “Safety
notes” on page 157.
Note
You can adjust the brightness of the warning lamps on the exterior
mirrors via the MMI ⇒ page 155.Applies to vehicles: with side assistSituation with vehicle approaching rapidly from behindFig. 167 side assist: Vehicles approaching rapidly from behind
Warning lamp on exterior mirror does not light up
The sensors have not detected any vehicles. The warning lamp on
the exterior mirror does not light up ⇒ in “Safety notes” on
page 157 .
Warning lamp lights up in information mode
The sensors have detected a rapidly approaching vehicle - in this
example in the left-hand lane. Because of its approach speed, this
vehicle is already judged to be critical in the event of a lane change
even though it is still some distance away. The warning lamp on the
exterior mirror lights up in the information mode ⇒page 151 .
Warning lamp flashes in warning mode
If you operate the turn signal in situation , the warning lamp on
the exterior mirror will flash briefly several times. This calls your
attention to the presence of a vehicle which you may have over-
looked.Note
•
The faster a vehicle approaches, the earlier the warning will
appear on the exterior mirror. In all cases, the side assist will give a
warning for the vehicles it has detected at the latest when they enter
the “blind spot”.
•
If a vehicle is approaching at high speed it is possible that a lane
change may be critical, even though no warning is given.

the blind spot Warning lamp on exterior mirror does not light up
The sensors have detected a slowly approaching vehicle - in this
example in the left-hand lane. Because it is relatively far away and
only approaching slowly, no warning will appear on the exterior
mirror ⇒ in “Safety notes” on page 157.
Warning lamp lights up in information mode
The slowly approaching vehicle is now closer. The warning lamp on
the exterior mirror lights up in the information mode.
The warning lamp on the exterior mirror will only light up if the side
assist calculates that the distance and the speed differential of
approaching vehicles would be critic al in the event of a lane change. In all cases, the side assist will light up to indicate the vehicles it has
detected at the latest when they enter the “blind spot”.

If you operate the turn signal in situation , the warning lamp on
the exterior mirror will still not give any warning ⇒ in “Safety

Applies to vehicles: with side assistAdjusting brightness of warning lamp on exterior mirror
You can adjust the brightness of the warning lamp on the
sound system or MMI*.– Select: Function selector button > Audi side assist
> Warning lamp: brightness .The brightness of the warning lamp in both the information and
warning modes is regulated automatically according to the ambient
light level. You can also adjust the basic brightness level of the
warning lamp yourself via the function Warning lamp: brightness.
The new brightness level will be displayed briefly while you are
making the adjustment. The brightne ss level that is shown at this
point is the intensity of the lamp when it comes on in the informa- tion mode. The intensity of the lamp in the warning mode is linked
to the intensity in the information mode.
The brightness of the lamp in the
information mode should be set
so that you can see the lamp when you glance at the exterior mirror,
but are not aware of it when l ooking forwards through the wind-
screen.
If you are in very dark or very light surroundings when you adjust the
brightness of the warning lamp, the automatic brightness control
may already have reached the lowest or the brightest setting. Under
these circumstances the brightne ss of the warning lamp on the
exterior mirror may not change visibly when you alter the basic
brightness level .
If you adjust the basic brightness level while the vehicle is in in very
dark or very light surroundings, the change in the setting may only
become visible in surroundings of more moderate brightness.
Note
•
The side assist is not active while you are changing the bright-
ness setting; the brief flash of the warning lamp is only intended to
help you make the desired setting.
•
Your personal settings are stored automatically and assigned to
the remote control key which is being used.
Applies to vehicles: with side assistGeneral notesThe side assist system has inherent limitations in some situations.
For this reason, please take particular care:•
When driving through bends ⇒page 156

Automatic gearbox
164moving the selector lever either in or out of position P. The lever can
only be moved out of position P when the ignition is on.
R - Reverse gear
When reverse gear is engaged the gearbox automatically selects the
lowest gear ratio.
Reverse gear must only be engaged when the vehicle is stationary
and the engine is idling ⇒.
To move the selector lever to position R, press in the interlock
button and at the same time press the brake pedal. Depending on
the model, one or two reversing lights will come on in selector lever
position R (when ignition is switched on).
N - Neutral
In this position the gearbox is in neutral ⇒.
D - Drive (forwards)
In this position the gearbox auto matically selects the best gear
ratio. This depends on the engine load, the road speed and the
dynamic gear control program (DCP).
Press the brake pedal when moving the selector lever from N to D if
the vehicle is stationary or at speeds below 5 km/h ⇒.
In some situations (such as on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to
tiptronic mode ⇒page 166 , so that the gear ratios can be selected
manually to suit the driving conditions.
S - Sport position
Select this position if you wish to take full advantage of the car's
performance. This setting makes use of the engine's maximum
power output. When accelerating the gear shifts will be noticeable.
Press the brake pedal when moving the selector lever from N to S if
the vehicle is stationary or at speeds below 5 km/h ⇒.
WARNING
•
Never move the selector lever to R or P when driving, as this
could cause an accident.
•
In selector position D or S the vehicle must always be held with
the foot brake when the engine is running. This is because an auto-
matic gearbox still transmits powe r even at idling speed, and the
vehicle tends to “creep”. The throttle must on no account be
opened inadvertently (for instan ce by hand from the engine
compartment) when a ge ar is engaged with the vehicle stationary.
The vehicle could otherwise star t moving immediately (in some
cases even if the parking brake is engaged) and possibly cause an
accident.
•
To avoid accidents, apply th e parking brake and put the
selector lever in position P befor e opening the bonnet and working
on the vehicle with the engine running. Please observe the impor-
tant safety warnings ⇒page 255, “Working on components in the
engine compartment”.Note
You can select the sport program for gear changes on vehicles with
Audi drive select* by activating the DYNAMIC mode. There is no S
position on the selector lever.•
Applies to vehicles with tiptronic gearbox:
•
If the lever is moved accidentally to N when driving, release the
accelerator and let the engine speed drop to idling before selecting
D or S again.
•
For the sake of fuel economy (and the environment), the gearbox
ratios on some models are designed so that maximum speed is only
obtained when the selector lever is at position S.

Audi parking system plusApplies to vehicles: with Audi parking system plusDescription
The Audi parking system plus is a parking aid with
acoustic signals and graphic display.Sensors are located in the front and rear bumpers. When the
sensors detect an obstacle, you are alerted by acoustic signals
(beeps) and a graphic display. The measuring range of the sensors
starts at about:
The acoustic signals sound with increasing frequency as you
approach the obstacle. A warning tone will sound continuously
when the vehicle is less than appr ox. 0.30 m away from the obstacle.
Stop moving immediately!
The volume of the warning beeps will be gradually reduced after
about 4 seconds if the vehicle remains at a constant distance from
a detected obstacle (it will not be reduced if the obstacle is closer
than 0.30 m).
Applies to vehicles: with Audi parking system plusSwitching on/offSwitching on

Segments in the graphic display
You can estimate the distance to an obstacle by referring to the red
segments at the front and rear of the vehicle ⇒page 170, fig. 186.
The closer the vehicle gets to the obstacle the closer the segments
move towards the vehicle in the graphic. At the latest when the
penultimate segment is highlighted the vehicle has reached the
danger (collision) zone. Stop moving immediately ⇒!
WARNING
•
The parking aid cannot replace the full concentration of the
driver. The driver is always resp onsible for safety during parking
and other manoeuvres.
•
The sensors have blind spots in which obstacles are not regis-
tered. It is particularly important to ensure that there are no small
children or animals near the vehicle, as the sensors may not
always be able to detect them.
•
Always keep a close wa tch on the area around the vehicle and
make full use of the rear-view mirrors.Caution
Please note that low obstacles detected by the system may no
longer be registered by the sensors as the car moves closer, so the
system will not give any further warning. Certain kinds of obstacles
(such as wire fences, chains, thin painted posts or trailer draw bars,
etc.) may not always be detected by the system, so take care not to
damage the vehicle in such cases.
Note
