Warning stage
If the d isplay i n a m irror blinks br igh tly when yo u
activate a turn signal, side assist is warning you
about detected vehicles that it has classified as
cr itical. If this happens, check traffic by g lancing
in the exterior mirrors and over your shoulder

Ap plies to vehicles with active lane assist
The display in the mirror can a lso b link if you
have not activated a turn signa l: if you are ap­
proaching a detected lane marker line and it ap ­
pears you w ill be leaving the lane, side assist will
warn you about detected vehicles that it has clas­ sified as critical.

:i: .. co
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some ­
what far away . The faster a vehicle approaches,
the sooner the display in the exterior m irror will
tu rn o n.
@ Vehicles traveling with you
Vehicles traveling with yo u are indicated in the
exter ior mirror if they are classified as cr itical for
a lane change . A ll vehicles detected by side assist
are ind icated by the t ime they ente r you r "blind
spot", at the lates t.
© Vehicles you are passing
If you s low ly pass a veh icle that s ide ass ist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph (15
k m/h)), the display in the exte rior m irror turns
o n as soon as t he veh icle enters your b lind spot .
The display w ill not t urn on if you quickly pass a
vehicle that side ass ist has de tected (the differ­
ence in speed is greater than 9 mph (15 km/ h)).
Function al limitat ions
The radar sensors are designed to detect the left
and right ad jacent lanes when the road lanes are
t h e normal width. In some situations, the display
in the exterior m irror may turn on even though
t h e re is no veh icle located in the area tha t is criti­
ca l for a lane change . For ex ample :
- If the lanes are na rrow or if your are drivi ng on
the edge of you r lane. If th is is the case, the ..,.

Ass is t
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
- If you are driving through a curve. Side assist may react to a vehicle that is one lane over
from th e adjacent lane .
- If s ide assist reacts to other objects (such as
high or d isplaced guard ra ils).
- In poor weather condit ions. The side assist
functions are limited.
Do not cover the radar sensors <=>
fig. 121 with
stickers, deposits, bicycle wheels o r othe r ob ­
jects, beca use they wi ll impair the function. Do
not use side ass ist when towing a trailer. For in­
formation on cleaning, see <=>
page 306.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
rep lace a driver's attention. The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers .
- In some situat ions, the system may not
func tion or its funct ion may be limited . For
example :
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in t ime .
- In poor weather conditions such as heavy
rain, snow or heavy mist .
- On very wide lanes, in tight curves, or i f
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
- Audi side ass ist cannot detect a ll vehicles
under a ll condit ions, which can increase the
risk of accidents.
- Please note that side assist only displays ap­ proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least
19 mph (30 km/h) .
- In certain situations, the system may not
work or its function may be limited. For ex ­
amp le:
- The display may not turn on at the rig ht
time if veh ides are approaching or passing
very q uick ly .
106
-
- In poor weather conditions, such as heavy
rain, snow or fog .
- In very wide lanes , in tight c urves or when
there are slopes in the roadway, vehicles
i n the ne ighboring lanes may not be de­
tected because they a re outside of the
sensor range .
(D Note
The sensors can be d isplaced by impacts or
damage to the bumper, wheel housing and underbody. This can impair the system. Have
an authorized Audi dealer or author ized Audi
Service Fac ility check their f unct io n.
@ Tips
- If the w indow glass in the dr iver's door or

0 co .... N ,..... N .... 0 0 :c ' Your vehicle is equipped with an intelligent ene r­
gy management system for distributing electrici­
ty. This s ignif icantly improves the starting abi lity
and increases the vehicle battery life.
The energy management system Is made up of
batt ery diagno sis , idling current management ,
and dynam ic energ y man agement.
Battery diagnosis
The batte ry diagnosis de termines the vehicle bat ­
tery charge level. The sensors determ ine the bat ­
tery voltage, the battery current, and the battery
temperature. The current charge level and the performance of the vehicle battery are deter­
mined based on th is.
Idling curr ent manag ement
The idling current management decreases the
energy used whi le parked . With the engine
switched off, it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this .
Depending on the vehicle battery charge level,
e lectrical equipment is sw itched off one item af ­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability .
Dynamic en erg y manag ement
While driving, dynamic energy management dis­
tr ibutes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to ma inta in an optimal veh icle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life a re
limited .
- When the start ing ability is endangered, the
(•) indicator light turns on
9 page 21.
Intellig ent Technology
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the veh icle battery
when driving short distances, during city driving, and at cold times of the year . A lot of energy is
used but little is generated. It is also critical
whe n the eng ine is not r unni ng but elect rical
equipmen t is switched on . In this case, energy is
u sed but none is generated.
In situat ions like th is, energy management w ill
active ly regulate the distrib ution of energy.
Long period s without use
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually scaled
back or sw itched off. This reduces energy use and
ensures the vehicle will be ab le to start after long
per iods of time. Some conven ience f unctions,
s u ch as interio r lig hting or power seat adjust­
ment, may no t be av ailable under certain circum­
stances . These conven ience f unctions wi ll be
available again once you sw itch the ignition on
and start the engine.
With the engine switched off
T he veh icle ba tte ry w ill dr ain if you use Info tain­
ment functions such as listening to the radio
whi le the engine is switched off.
If the sta rting abili ty is impaired by the energy
u se, the following message will appear in the In ­
fotainment system display:
Please start the engine , otherwi se the system
will turn off shortl y.
This message indicates that the system will
switch off automatically after 3 m inutes . If you
would like to continue us ing the funct ions, you
must start the engine.
With the engine running
Although e lectr ica l energy is generated while
driv ing, the ve hicle battery can drai n. This can
happen if litt le energy is generated b ut much is
used , and the charge level of the vehicle battery
is not optimal. .,.
