Please note that convenience ope ning re­
quires one additional action for vehicles
equipped with ant i-theft a larm . This applies
to convenience closing as well.

You should always lock the steering whenever
you leave your vehicle . This makes a vehicle
theft even more difficu lt ¢ & .
Ignition ke y safe ty lock
After switching off the ignition, the ig nit ion
key can only be removed from the ign ition
l ock when the selector lever is in the "P"
(Park) position . After you have removed the
key, the selector lever is locked and cannot be
moved.
Ignition on @
If it is difficult to turn the key after you have
inse rted it into the ignition lock, turn the
steering whee l back and forth. This will take
the load
off the steering lock mechan ism and
you will be able to turn the key freely and start the engine.
Starting the engin e@
In this position the engine starts . While the
engine is starting, the power supply to the headlights and other e lectr ica l consumers is
tempo rarily interrupted to conserve battery
power . After the engine has started, release
the key and it will return to posit io n @ .
Before the starter can be operated again the
key must be turned back to position@. The
non-r epeat lock prevents you from damag ing
the sta rter when the engine is runn ing .
A WARNING
-Never remove the key from the ign ition
lock whi le the vehicle is moving. The
steering wheel will lock causing loss of
control.
- If you have to leave your ve hicle -even
f or just a m in ute -always remove the ig­
ni tion key and take it with you. This is es­
pecially important if yo u a re going to
leave chi ldren behind in the vehicle. The
children cou ld start the engine or use
other vehicle controls. Unsupervised use
of vehicle controls (for example, power
windows) can cause serious personal in­
jur ies .

(D Tips
If the vehicle battery has been disconnect­
ed and then reconnected, then yo u must
l eave the key in posit ion @ for about 5
seconds before you can start the engine.
Starting and stopping
the engine
' Starting the engine
The engine can only be started with an origi­
nal Audi key .
.,. Se t the par king brake.
.,. Move the selector lever in P or
N q ,& .
.,. Tu rn the ignition key to position ®
~ page 80, fig. 90 -do not depress the gas
peda l when starting the engine!
.,. Let go of the key as soon as the engine
starts.
A cold engine may at first be loud after it has
been started. This is due to the hydraulic
valves bu ild ing up the oil pressure. Th is nor­
mal and no need for concern .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.
- Never leave the engine id ling unattend­
ed. An una ttended veh icle with a runn ing
engine poses a danger o f personal injury
or theft .
(D Note
-Avo id high engine speeds, fast accelera­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
engine.
- The engine cannot be started by pushing
or towing the vehicle . .,..

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 bat­
tery is discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle handles the d istribution of electrical ener­
gy. Starting ab il ity is markedly imp roved and
the life of the battery is extended .
Basically, energy management consists of
batt ery diagno sis, idlin g current man ag e­
m ent
and dyn ami c en ergy manag emen t.
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determ ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces energy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the various electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the batte ry's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the battery
and thus maintain starting capability .
Dynam ic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 155
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
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
r::!)poge 156,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -distance
driving, 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 be ing consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat ­
ing the d istribution of energy .
Vehicle stands for an e xtended peri od
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in ­
ta ins start ing capability over a longer period .
Take into considerat ion that when you unlock
your vehicle, some convenience functions, such as the remote key or power seat adjust­
ment, may not be available . The conven ience
funct ions w ill be available again when you
tu rn o n the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off, the battery is being d is-
charged.
