Intelligent Technology
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management,
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine 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 this.
Idling current management
The idling current management decreases the
energy used while 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,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical 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 maintain an optimal vehicle battery charge level.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life are
limited.
- When the starting ability is endangered, the
(•) indicator light turns on ~ page 21.
132
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle 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
when the engine is not running but electrical
equipment is switched on. In this case, energy is
used but none is generated.
In situations like this, energy management will
actively regulate the distribution of energy.
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually scaled
back or switched off . This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances. These convenience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will drain if you use Infotain­
ment functions such as listening to the radio
while the engine is switched off.
If the starting ability is impaired by the energy
use, the following message will appear in the In­
fotainment system display:
Please start the engine, otherwise the system
will turn off shortly.
This message indicates that the system will
switch off automatically after 3 minutes. If you
would like to continue using the functions, you
must start the engine.
With the engine running
Although electrical energy is generated while
driving, the vehicle battery can drain. This can
happen if little energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.

- Never store items under the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat cou ld be dam­
aged, preventing them and the airbag sys­
tem from worki ng p roperly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by A ud i on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizi ng ch ild

restraints or occupants on the front passen­
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat.
The additional padding will prevent the
weight-sensing mat in the seat from accu­
rately registering the child restraint or per­
son on the seat and prevent the Advanced
Airbag System from functioning properly .
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the child restraint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position and have the airbag system inspected by
your Audi dealer .
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts and the adjustable head restraints to help reduce the risk of injury in
a wide range of accident and crash situations . Be
sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­ pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side , regardless of safety belt
use, the airbag will be turned off if the weight on
~ the passenger seat is less than the amount pro-...,
~ gram med in the electronic control unit. The front N
8 airbag on the passenger side will also be turned 0 :c ' Airbag system
off if one of the child seats that has been certi­
fied under Federal Motor Vehicle Safety Standard
208 has been recognized on the seat. The
PAS­
SENGER AIR BAG OFF
light comes on and stays
on to tell you when the front Advanced Airbag on
the passenger side has been turned off
~ page 228, Child restraints on the front seat ­
some important things to know .
_&. WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­

airbags
Fig. 231 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­ plemental protection in a frontal collision .
The front airbags are designed to provide addi­
tional protection for the chest and face of the driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag,
- and the head restraints have been properly ad-
justed .

the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between

cause breathing problems for people with a
history of asthma or other breathing condi­
tions.

ditions should get fresh air right away by
gett ing out of the veh icle or opening w in­

" ~ tion is on. Each time you switch on the ignition,
~ the airbag monitoring indicator light fl (USA ' Airbag system
models)/EI (Canada models) w ill come on for a
few seconds (se lf diagnostics).
