Driving 122a fault in the parking brake. Have the fault repaired by a qualified
workshop without delay ⇒page 32.
Note
•
The parking brake can be applied at any time - even when the
ignition is switched off. However, the ignition must be switched on
before the parking brake can be released.
•
Any slight noise which may be heard when the parking brake is
applied or released is quite normal and no cause for concern.
•
The parking brake runs an automatic test cycle at regular inter-
vals when the vehicle is parked. This may also cause a slight noise,
which is normal.
Parking
Please note the following points to ensure there is no risk
of the car rolling away accidentally after it is parked.Parking t he c ar
– Use the foot brake to stop the vehicle.
– Pull the switch to apply the parking brake.
– Automatic gearbox: Move the selector lever to P.
– Switch off the engine ⇒.
– Manual gearbox: Engage the first gear.
When parking on slopes
– Turn the steering wheel so that the vehicle would roll into
the kerb if it did start to move accidentally.
WARNING
•
Always take the key with you when leaving the vehicle – even
if you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine, release the parking brake or use power-
operated equipment such as the electric windows - this could lead
to injuries.
•
Do not leave anyone (especially children) in the vehicle when it
is locked. Locked doors could delay assistance in an emergency,
potentially putting lives at risk.

The parking brake auto release function releases the
parking brake automatically when you wish to start
moving.Applying the parking brake when stopping
– Pull the switch to apply the parking brake.
Releasing the parking brake when driving away
– Drive off in the normal way: the parking brake will be
released automatically and the vehicle will start moving.On vehicles with automatic gearbox, you can apply the parking
brake when stopping at traffic lights, etc. Then you do not have to
hold the car with the footbrake, as the parking brake will stop it
creeping forward while a gear is engaged in the automatic transmis-
sion. When you drive off in the normal way, the parking brake will be
released automatically and the vehicle will start moving.
Driving away on a slope
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The

Technical data lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
 in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.
As soon as you drive off in the normal way, the parking brake will
automatically be released and the vehicle will start moving.
If the conditions for Audi hold assist change and the function is
switched off as a result, the parking brake will be applied automati-
cally to ensure that the vehicle is parked safely. The diode in the
button will go out when the Audi hold assist function is switched
off.
WARNING
The intelligent technology in Audi hold assist cannot defy the laws
of physics. Do not let the extra convenience provided by Audi hold
assist tempt you into taking a safety risk.•
Audi hold assist cannot keep the vehicle stationary in all condi-
tions on a gradient (e.g. if the road is slippery or icy).
•
Audi hold assist must be switched on again each time the
engine is started – Risk of accident!
•
Never get out of the vehicle when the engine is running and
Audi hold assist is switched on – Risk of accident!
•
Always ensure that the vehicle is stopped properly and safely
to avoid injury to yourself and others.Caution
Switch off the Audi hold assist function before driving the vehicle
into a car wash.
Note
•
Audi hold assist can be switched on only when the driver's door
is closed, the driver's seat belt is buckled and the engine is running.
•
Audi hold assist prevents automatic vehicles from creeping
forwards when the brake pedal is released with the car in gear.
•
When the vehicle has been stationary for an extended period,
Audi hold assist will automatically apply the parking brake. In this
case, the green symbol
 in the instrument cluster display will
change to red

– Pull the lever to position ⇒page 125, fig. 134 to
switch on the system.
– Drive at the speed you wish to set the system to.
– Press the button marked to store the speed.The display will indicate the stored speed, and the green symbol

will appear ⇒fig. 135. The display can vary according to the display
status. In addition, the indicator lamp
 in the instrument cluster
will light up.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always the driver who is
responsible for determining the speed and for keeping a safe
distance to the other vehicles on the road.
•
For safety reasons, the cruise control system must not be used
in city traffic, stop-and-go traffic, roads with a lot of bends or in
difficult driving conditions (such as ice, fog, loose grit or gravel,
heavy rain, aquaplaning) - this could cause an accident!
•
When you take a turn-off, drive along a motorway exit lane or
pass through roadwork sections, please temporarily switch off the
cruise control system.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the cruise control system which,
as a result, will not brake the vehicle.Note
•
Vehicles with manual gearbox: The set speed cannot be reached
if the currently selected gear is too high or too low. Change down to
a lower gear if the engine is no longer running smoothly or change
up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.
Applies to vehicles: with cruise control systemAdjusting the speed– Push the lever up towards or down towards
⇒page 125, fig. 134 in order to increase or reduce the
cruising speed setting.
– Release the lever to store the current cruising speed.You can alter the set speed in steps of 1 km/h by briefly pressing the
lever upwards or downwards. When you press and hold the lever,
the speed is changed in steps of 10 km/h.
You can still use the accelerator pedal to increase speed in the
normal way, for example to overtake another vehicle. Once you
release the accelerator, the system will revert to the speed you
stored initially.
However, if the vehicle exceeds the programmed speed by more
than 10 km/h for more than 5 minutes, the cruise control system will

Technical data
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.
