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 resu lt
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.
Basical ly, energy management consists of
battery di agn osis, idling
current mana gement
and dynami c en ergy management .
Batter y diagn osis
Battery diagnosis continuously deter min es the state of the battery.
Sensors determine battery vo ltage, battery current and battery
temperature . This determines the cu rrent state of charge and the
power of the battery .
Idling c urrent man ag em en t
Idling current management reduces energy consumption while the
vehicle is standing. With the ign it ion switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnos is is considered .
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 energ y managem ent
While the vehic le is being driven, dynamic energy management
distributes the energy gene rated acco rding to the needs of the indi -

ment Safety first Vehicle operation

vidual components . It regulates consumption, so that more e lec­
trical energy is not being used than is being ge nerated 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 .
• I f starting ability is threatened, you are informed by a warning
=> page 266, "Drive r notifica tion i n the instrument cluster
display" .•
What you should know
The highes t pri ority is given to main tain ing starting capa ­
bility.
The battery is severe ly taxed in short-distance driving, in city traffic
and during the co ld 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 elect rica l components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you will notice energy manage ­
ment active ly regula ting the distr ibut ion of energy.
Vehicle stands fo r 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.
Take into considerat ion that when you un lock your veh icle, some
convenience functions, such as the remote key or power seat
adjustment, may not be availab le . T he conven ience functions will be
available again when you turn on the ignition and start the engine.

Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced .
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage => &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ & .
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake .
& WARNING (continued)
• Move selector lever to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment .
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.

With certain types of airbag deployment, the battery is discon­
nected from the vehicle electrical system for safety reasons=>&. in
"Repair, care and disposal of the airbags" on
page 226.
Di sc o nnect ing the b attery t ermin als
Some vehic le functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These func tions have
to be relearned after the battery terminals are connected again . To
prevent this, the battery should only be disconnected from the
vehic le electrical system when absolute ly necessary for repairs.
V ehicle s not driven for long period s
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 265.
Take into consideration that when you un lock your vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience
functions will be availab le again when you turn on the ignition and
start the engine .
Winter oper ation
During the w inter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while s tarti ng, an d the headlights, rear wi ndow defogger, etc ., are
used more often.
Avoid unnecessary p ow er consumption, particularly in ci ty traffic or
when trave ling only short distances. Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=> page 310. A we ll charged battery wil l not on ly prevent starting
problems when the weather is cold, but wi ll also last longer.
[ i J Tips
If your vehicle is left standing for severa l weeks at extremely low
t empera tures, the vehicle ba ttery should be r emoved and stored where it will not freeze
. This will prevent it from being damaged and
having to be replaced .•
