Audi side assistLane change assist featureApplies to vehicles: with side assistDescription
The side assist function assists the driver when changing
lanes.The side assist function employs radar sensors ⇒fig. 163 to assist
the driver in monitoring following traffic and the blind spots on both
sides of the car ⇒page 151, fig. 166.Warning lamps are incorporated in the two exterior mirrors
⇒fig. 164. The warning lamp on the left-hand mirror assists the
driver when changing lane towards the left and the warning lamp
on the right-hand mirror assists the driver when changing lane
towards the right.
When one of these lamps lights up, this is to inform you that the
side assist has detected a vehicle on that side and calculates that a
lane change would be critical. This is the first stage of the warning,
referred to as the information mode ⇒page 151. This stage of the
warning is designed to be visible only when you look in the exterior
mirror.
If you operate the turn signal when the side assist has registered
what it judges to be a critical vehicle, the lamp on the exterior mirror
will then flash several times with greater intensity. This is the
warning mode ⇒page 151.

Audi side assist 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 that 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.

Applies to vehicles: with side assistSituation with vehicle approaching slowly from behindFig. 168 side assist: Vehicles approaching slowly from behind and vehicles in
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 critical 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”.

Audi drive selectAdjusting the vehicle set-upApplies to vehicles: with Audi drive selectIntroductionAudi drive select allows you to use different set-ups on your vehicle.
Using the three modes COMFORT, AUTO and DYNAMIC, you can
change the set-up at the press of a button for a more comfort-
oriented or dynamic drive.
On vehicles with MMI*, you also have the INDIVIDUAL* mode, which
allows you to adapt the vehicle set-up individually to your personal
driving style. For example, you might choose to combine a more
dynamic engine set-up with a lighter steering response.Applies to vehicles: with Audi drive selectDescriptionThe possible vehicle set-up in each mode depends on which equip-
ment is installed on your vehicle. The engine and the servotronic
power steering are basic parts of your vehicle which are always
included in the set-up. In addition, you can change the characteris-
tics of the automatic gearbox*, dynamic steering* and suspension
control*.
The response of the engine and automatic gearbox* to accelerator
pedal movements will be more spontaneous or balanced,
depending on which mode you select.
The servotronic power steering ⇒page 225 will also respond to
different drive set-ups.
The dynamic steering* alters the steering ratio depending on the
road speed to optimise the amount of steering effort required by the
driver at any given time. This enables the sensitivity of the steering to be reduced at higher speeds in order to improve the handling of
the vehicle. The steering is more direct at lower speeds to minimise
the amount of steering effort required by the driver, e.g. when
manoevring in tight spaces. The dynamic steering* also provides a
more agile steering response at low and medium speeds. You can
adjust the basic characteristics of the steering in the Audi drive
select menu.
The suspension control* uses sensors to collect information on
steering movements, braking and acceleration input by the driver,
road surface quality, road speed and vehicle loading. Using this
information, the suspension can be adapted almost instantane-
ously to changing driving conditions. With Audi drive select, the
driver can choose between dynamic and comfort-oriented suspen-
sion set-ups (DYNAMIC and COMFORT modes), or opt for a more
balanced set-up (AUTO mode).
The following table provides an overview of the characteristics in
each driving mode.
If your vehicle is equipped with dynamic steering*, the servotronic
power steering settings are adjusted in the Dynamic steering*
menu.

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 automatically 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 power even at idling speed, and the
vehicle tends to “creep”. The throttle must on no account be
opened inadvertently (for instance by hand from the engine
compartment) when a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving immediately (in some
cases even if the parking brake is engaged) and possibly cause an
accident.
•
To avoid accidents, apply the parking brake and put the
selector lever in position P before 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.

Automatic gearbox 166
WARNING
Please note that if the road surface is slippery or wet, the kick-
down feature could cause the driving wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic® or tiptronicDynamic gear control program (DCP)
The automatic gearbox is controlled electronically.The vehicle is equipped with an electronically controlled gearbox.
The gear ratios are selected automatically according to preset gear-
shift programmes.
When you drive at moderate speeds the gearbox will select the most
economical shift programme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the
throttle quickly, or if you use the kick-down or the car's maximum
speed, the gearbox will automatically select the more “sporty” shift
programmes.
The gearbox is self-adapting, and continuously selects the most
suitable shift programme. At the same time, the driver can also
make the gearbox switch to a more "sporty" programme by pressing
the accelerator quickly. Depending on road speed, this makes the
gearbox shift down early into a lower gear ratio for more rapid accel-
eration (for instance to pass another vehicle), without having to
press the accelerator all the way down into the kick-down position.
After the gearbox has shifted back up it returns to the original
programme, depending on your style of driving.
Vehicles with multitronic® gearbox: The gearbox continuously
adapts the gear ratios on uphill gradients. If the brake pedal is
pressed on a downhill gradient the gearbox automatically shifts to
a lower gear ratio. This increases the engine braking effect.Vehicles with tiptronic gearbox: The gearbox adapts the gearshifts
for uphill and downhill gradients. This prevents the gearbox from
shifting up and down unnecessarily on uphill gradients.
Applies to vehicles: with multitronic® or tiptronicManual gear selection (tiptronic mode)
With the manual shift programme (tiptronic) the driver
can manually select pre-programmed gears.Switching over to the manual programme
– From position D, push the selector lever to the right. As
soon as the automatic gearbox has changed over to this
programme, the display will show the selected gear.
