The short -term memory collects driving informa­
tion from the time the ignition is switched on un­
til it is switched off . If you cont inue driv ing with­
in two hours after switching the ignition off, the
new values are included when calculat ing the cur­
rent tr ip informat ion.
Unlike the short-term memory, the long-term
memory is not erased automat ically. You can se­
lect the time period for evaluat ing trip informa­
tion yourself .
Fuel con sumpti on
The current fue l consumption can be shown us­
ing a bar graph
cc> fig. 14. The average cons ump­
tion stored in the short-term memory is also dis­
played. If the bars are green or the gray tone on
the bars changes (depending on the equipment),
your veh icle is sav ing fuel by the following func­
tion:
- Recupe ration : electrical energy can be stored in
the ve hicle battery when the vehicle is coasting

Audi pre sense city
Description
Applies to: vehicles with Audi pre sense city
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble braking maneuver if needed. Pre sense city is
active at speeds of approximately 6 mph (10 km/ h) and higher.
A pedestrian warning can occur at speeds up to
50 mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h) . A pre
sense city braking maneuver is poss ible at speeds
up to 50 mph (85 km/h).
Warnings
Applies to: vehicles with Audi pre sense city
The system recognizes various dangerous s itua­
tions. The
early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary veh icle in the direc­
t ion of travel.
- a pedestrian is standing in the lane or is moving
i nto the lane .
When this warning occurs, it may only be possi­ ble to avoid a collision by swerving or braking
strongly. The message
Audi pre sense .
Assistance systems
¢page 121, fig. 122 and a warning tone will
warn you about the danger.
Additionally, a jerk on the brakes may occur as an
acute warning when there is an imp ending colli­
sion . If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
celeration within the limits of the system . T his
reduces the vehicle speed in the event of a colli­
sion. The message
Audi pre sense . also ap­
pears.
The following functions are triggered in conjunc­
tion with pre sense basic/rear:
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof* .
- Inflating the side bolsters* on the seat back-
rest.
Audi drive select*: the function is not act ive de­
pending on the mode selected.
A WARNING
- Pre sense city cannot overcome the laws of
physics.
It is a system designed to assist and
it cannot prevent a coll is ion in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks.
This could increase your risk of a collision.
- The system can dep loy incorrectly due to
system-specific limits.
- To reduce the risk of an accident, please
note that the camera does not always detect
every object.
- Pre sense city does not react to anima ls,
crossing or oncoming vehicles, objects such
as bars, railings or railcars, and objects that
are difficult to
detect ¢ A in General infor­
mation on page 109 .
-In trailer mode, the braking behavior of the
tra iler can be d ifferent than usual during au­
tomatic braking.
A WARNING
-Pre sense city may be restricted or not availa-
ble in the following example situations:
- in heavy fog, ra in, spray or snow

tem p lus/rearv iew camera/peripheral ca meras
Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 137.
The
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 137.
The
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or
maneuver ¢ page 138. The parking sys­
tem plus functions are also available
¢ page 137.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢ page 140. The parking system plus functions
are also available
¢page 137.
A WARNING ,..__ -
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
- Please note that some surfaces , such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always keep your eyes on the vehicle's sur ­
roundings, using the rearview mirror as
well.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­ ing system may be impa ired as a result.

Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
(D Note
- Some objects are not detected or displayed
by the system under certain circumstances:
- objects such as barrier chains, trailer draw
bars, vertical poles or fences
- objects above the sensors such as wall ex ­
tensions
- objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
{i) Tips
- The system may provide a warning even
though there are no obstacles in the cover ­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- external ultrasonic sources such as from
cleaning vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 143.
- Please refer to the instructions for towing a
trailer located in
¢page 144.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .
- Th e rearv iew camera is automatically
cleaned when cleaning the rear window*

Deactivating the convertible locking
retractor
The convertible locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way back into the re­
tractor .
~ Press the red button on the safety belt buckle.
The belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position. The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints.
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deact ivate this feature. If the
convert ible locking retractor is not deactivated,
the safety belt w ill gradually become tighter and
uncomfortable to wear.
_& WARNING
-
Improperly installed chi ld safety seats in­
crease the risk of serious personal injury and
death in a collision.

LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicab le way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
" Lower Anchorages and Tethers for Children". In
Canada, the terms
"top tether" with "lower uni­
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September
1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r without one can seriously impair the per­
formance of the child restraint and its ab ility to
pro tect the child in a collision. Installing a child
restra int that requi res a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats w ith hook-on or
