2010 AUDI A5 COUPE immobilizer

- Have the electrical system inspected by an authorized
Audi dealership. •
Starting the vehicle with the emergency key
Fig. 34 Glove compart­
ment: Adapter for
emergency key
Fig . 35 Insert emer­
gency key into the
adapter
- Take the adapter for the emergency key out of the glove
box~ fig. 34.
- Push the emergency key~ fig. 35 fully into the adapter.
Make sure that the Audi rings are facing up.
- Press the emergency key in the adapter down until it
latches audibly.
Contro ls and eq uip­
ment
Opening and closing
-Insert the adapter with the emergency key forward into
the ignition switch. The engine can now be started as
usual. •
Electronic immobilizer
The immobilizer prevents your vehicle from being started
by unauthorized persons.
Inside the key there is a computer chip. This chip automatically
deactivates the electronic immobilizer when you insert the key in
the ignition lock. When you remove the key from the ignition lock,
the elec tronic immobilizer is automatically activated once again.
I f an unauthorized key was used,
SAFE is displayed continuously in
the odometer display field.
[ i] Tips
• Your engine can only be started using the factory-equipped key.
• You may not be able to start your vehicle if an ignition key of a
different vehicle make is also located on your set of keys.
• For Declaration of Compliance to United States FCC and Industry
Canada regulations~ page 342. •
Power locking system
General description
The power locking system locks or unlocks all doors and
the rear lid simultaneously.
You can lock and unlock the vehicle centrally. You have the following
choices :
• Remote master key~ page 43, .,,.

vehicle. Always drive at speeds which are suited to the road condi­
tions -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 .
If a vehicle with a conventional energy system is not driven for a
long period of time , the battery 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.
Intelligent energy management in your vehicle handles the distribu ­
tion of electrical energy. Starting ability is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
battery diagnosis, idling
current management
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines the state of the battery.
Sensors determine battery voltage, battery current and battery
temperature. This determines the current state of charge and the
power of the battery.
Idling current management
Idling current management reduces energy consumption while the
vehicle is standing . With the ignition switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnosis is considered.
Controls and equip­ ment Safety first Vehicle operation
Intelligent technology
Depending
on the battery's state of charge, individual consumers
are gradually turned off to prevent excessive discharge of the
battery and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy management
distributes the energy generated according to the needs of the indi­
vidual components. It regulates consumption, so that more elec­
trical energy is not being used than is being generated and ensures
an optimal state of charge for the battery.
[ i] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 242, "Driver notification in the instrument cluster
display". •
What you should know
The highest priority is given to maintaining starting capa­
bility.
The battery is severely taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
required, but only a little is generated. It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in precisely these situations that you will notice energy manage ­
ment actively regulating 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, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.

~ page 263.
0 Note
• If items other than genuine Audi spare par ts, add-on equipment
and accessory items are used or if repair work is not performed
according to specified methods, this can resu lt in severe damage to
your vehicle 's engine and body (such as corrosion) and adverse ly
affect your vehicle's warranty .
• If emergency repairs must be performed elsewhere, have the
vehic le examined by an authorized Audi dealer as soon as possible.
• The manufacturer cannot be held liable for damage which occurs
due to fai lure to comply w ith these stipu lations. •
Technical Modifications
Our guidelines must be c omplied with when technical
modifi cations are made.
Always consult an authorized Audi dealer before starting work on
any modifications.
This will he lp ensure that vehicle function, performance and safety
are not impaired ~& .
Attempting to work on e lectronic components and the software
used with them can cause malfunctions. Because of the way e lec­
tronic components are interconnected with each other, such
malfunctions can also have an adverse affect on other systems that
are not directly involved . This means that you risk both a substantial
reduction in the operational safety of your vehicle and an increased
wear of vehicle parts~& . Authori
zed Audi dealers will perform this work in a professiona l and
competent manner o r, in special cases, refer you to a professiona l
company that specializes in such modifications .
