@ Remote control key or conven ience key*
The convenience key is a remote control key with
specia l functions ¢
page 24 and¢ page 61.
With the remote cont rol key, you can lock and
u nlock the vehicle and sta rt the eng ine . To fold
the key out and back in p lace, press the release

Replacing a key
If a key is lost, see an authorized Audi dealer or
author ized Audi Service Facility. Have
this key de­
activated .
It is important to bring a ll keys with
you .
If a key is lost, yo u should report it to you r
in su rance company.
Number of keys
You can check the number of keys ass igned to
your veh icle in the instrument cluste r d isplay. It
will show you th is when you ad just the time

keys tot al ass igned to th e vehicle. This w ay, yo u
can ma ke sure that you have all the keys whe n
pur chasing a used vehicle .
Electronic immobilizer
The immob ilizer prevents unautho riz e d use of
t he vehicle.
Unde r certain c ircumstances , the vehicle may not
be ab le to s tart if the re is a key from a different
ve hicl e manufact urer on the key cha in.

Intelligent Technology
- Note that on wet streets, the front wheels
can "hyd roplane" if d riving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hyd roplaning.
Fo r this reason, adap t your speed to the
road co nditio ns to reduce t he risk of an acc i­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle w ith a conventional e nergy sys­
tem is not driven for a long time, the vehicle bat ­
tery is dra ined by equipment (for example, the
immobilizer) . In certain circumstances, there
could may not be enough energy to start the en ­
gine .
Your veh icle is equipped with a n intelligent ene r­
gy management system for d istr ibut ing electric i­
ty . This s ignificantly improves the sta rting ability
a nd increases t he ve hicle battery life .
The energy management system Is made up of
battery diagnosis , idling current management ,
and dynamic energy management .
Battery diagnosis
The batte ry diagnos is determines the ve hicle bat­
tery charge level. The sensors dete rm ine the bat ­
tery voltage, the battery cur rent, and the battery
temperature. The c urrent charge level and the
pe rformance of the veh icle battery are deter ­
m ined based on th is .
Idling current management
The idling cu rrent management dec reases the
e n ergy used wh ile parked . With the eng ine
sw itched off, it manages the energy distribution
to the differe nt elect rical components. Data from
t he batte ry diagnos is is taken into account fo r
this.
94
De pend ing on the vehicle batte ry c harge level,
e lectrica l eq uip ment is switched off one item af ­
te r the other to p revent t he vehicle battery from
dra ining and to ma inta in the starting ab ility.
Dynamic energy management
W hile driv ing , d ynam ic ene rgy man ageme nt di s­
tribu tes the ap propr iate amo unt of energy to t he
electrica l eq uip ment . It contro ls t he battery
c h arge level so that the amount o f energy is not
greater than the amount being generated in or ­
der to maintain an opt imal vehicle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics. Not e that the charge level
and length of the veh icl e bat tery life a re
limited .
- Wh en the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority .
A lot of st ress is placed on the veh icle battery
whe n driving short distances, d uring city d riving,
and at cold times of t he year. A lot of ene rgy is
u sed but li tt le is generated .
It is also critical
whe n the engi ne is no t ru nning but electrical
equipmen t is sw it c hed on . In t his ca se, energy is
u sed but none i s generate d.
In si tuati ons like t his, energy management w ill
ac tiv el y regulate the d is tr ibution of energy .
Long periods without use
If you do not drive yo ur vehicle for severa l days o r
wee ks, electrica l equ ipment is g radua lly sca led
bac k or sw itched off . Th is reduces energy use and
ensures the vehicle will be ab le to s tart a fter long
p er iods o f time . Some conven ience f unct ions,
s uch as in terior lig htin g, m ay not be available un ­
d er cert ain circu m sta nces. These c onve nien ce
f unct ions w ill be avail able ag ain once yo u sw itch
t h e ignit io n on and sta rt the eng ine. .,.
