2015 AUDI Q7 immobilizer

40 Opening and clo sing
@ Tips
Please note that the current state of the
veh icle door locks can only be recalled with
the master key that was last used to lock
the vehicle . It is possible that a different
state is shown for the door locks on the
other master key wh ich is not the same as
that of the vehicle .
Master key battery replacement
Each master key contains a battery housed
under the cover .
Fig. 30 Master ke y: opening the cove r
.. Pry apart the base q fig. 30@ and the cover
@ carefully with a coin.
.. Remove the cover (arrow) .
.. Remove the dead battery from the cover.
.. Install the new battery. Please make certain
that the" +" sign on the battery faces down
in the cover . Correct polarity is shown on the
cover .
.. Place the cover with the new battery on the
key base and press both parts together.
@ For the sake of the environment
Dispose of dead batteries properly so as
not to po llute the environment.
@ Tips
The replacement battery must be the
same specification as the or iginal.
Electronic immobilizer
T he immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip in side your key automatically
deac tivate s the elec tronic immob ilizer when
you insert the key in the ignition lock , or on
vehicles with Convenience key*, when the key
is ins ide the veh icle. When you remove the key
from the ignition lock, or on vehicles with
Convenience key, when you remove the key
from the vehicle, the electronic immobilizer is
automatica lly activated once again.
WARNING
Always take the key with you when you
l eave the vehicle. The key can disarm the
electronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operation of the vehicle sys­
tems such as power w indow or Panoramic
slid ing sunroof* leading to serious person­
al injury.
u) Tips
-The vehicle cannot be started if an unau­
thorized key is used . The vehicle may not
start if another radio device such as a key
for another vehicle or a transponder is
located on the key ring.

will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive vehicle. Always drive at speeds wh ich are suited to the road con­
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
I f a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is discharged by idling current consumers
(e.g. immobilizer) . In certain circumstances it
can result in there being insufficient energy
available to start the engine.
I ntelligent energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting ability is markedly improved and
the life of the battery is extended.
Basically , energy management consists o f
battery diagnosis, idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus ma intain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic en­
ergy management distributes the energy gen ­
erated according to the needs of the individu­
al components.
It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
(!) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is threatened, you are
informed by a warning
¢ page 229,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driv ing, in city traffic and during the cold time
of year. Abundant electrical energy is re­
quired, but only a little is generated . It is also
critical if the engine is not running and electri ­
cal components are turned on. In this in­
stance energy is being consumed but none is
being generated.
It i s in precise ly these s ituations that you will
notice energy management actively regu lat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ica l compo­
nents are gradually cut back or sw itched off.
T his reduces energy consumption and ma in­
ta ins starting capability over a longer period.
T ake into consideration that when you unlock
your vehicle, some convenience functions,
such as the interior lights or the power seat
adjustment, may not be availab le. The con­
venience functions will be availab le again

Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authorized Aud i dealer be ­
fore starting work on any modifications.
This will he lp ensure that vehicle function,
performance and safety are not impaired
¢ .&. .
Attempting to work on electronic components
and the software used with them can cause
malfunctions. Beca use of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di ­
rectly involved . Th is means that you r isk both
a substantial reduction in the operational
safety of you r vehicle and an inc reased wea r of
vehi cle parts¢ _&..
Author ized Audi dealers w ill perform th is
wo rk in a professiona l and competent ma nner
or, in spec ial cases, refer you to a p rofessional
company that specializes in such mod ifi ca­
tions .
_& WARNING t= -
Improper repairs and modifications can
change the way vehicle systems wo rk and
cause damage to the veh icle and ser ious
personal injury.
(D Note
If emergency repairs must be performed
elsewhere, have the veh icle examined by
an authorized A udi dealer as soon as possi­
ble.
