Energ y man ag em ent
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 295.
Heating systems in particular require a great deal of energy. If you
notice, for example, that the seat * or rear window heating is not
heating, they have been temporarily cut back or switched off by
ene rg y m anage ment. These systems are available again as soon as
the energy balance has been res tored .

[ i ] T ip s
• Keep the air intake slots (in front of the windsh ie ld) free from ice,
snow and debris in order to maintain the proper function of the
climate contro l system.
• Air inside the vehicle escapes through air vents located in the
s ide tr im panels beneath the rear side windows. Make sure that the
out let slots are not covered by clothing, etc.
• Climate control works most effectively if the windows and the
Panoramic s liding sunroof* are c losed. However, if the interior of a
parked vehic le is extreme ly hot from the sun's rays, briefly opening
the windows can speed up the cooling process. •

possible that vehicles will be detected that are
not in th e lane next
to the lane yo u are us ing.
& WARNING
• Improper reliance on the side assist system can cause colli ­
sions and serious personal injury :
- Never rely only on side assist when changing lanes.
- Always check rear view mirrors to make sure that it is safe to
change lanes .
• Side assist cannot detect all vehicles under all conditions ­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly .
• The radar sensor's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side assist not
adequately detecting vehicles or , in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet , or 100 ml.
• Side assist is no replacement for the driver's full attention. The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle. .,,_

& WARNING (continued)
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua ­
planing) . If this should occur , you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
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.
Controls and equip­ ment Safety first Vehicle operation
Intelligent technology
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.
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.
• I f starting ability is threatened, you are informed by a warning
~ page 296, "Driver notification in the instrument cluster
display". •
What you should know
-----------------
The highest priority is given to maintaining starting capa-
bility.
Th e 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 litt le 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.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat
adjustment, may not be available. The convenience functions will be
available again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged.
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes.
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions,
you have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers
which require especially large amounts of energy are temporarily
cut back or switched off. Heating systems in particular require a
great deal of energy. If you notice, for example, that the heated
seats* or the heated rear window are not heating, they have been
temporarily cut back or switched off. These systems will be available
again as soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased
slightly. This is normal and not a cause for concern. By increasing engine idle speed the additional energy required is generated and
the battery is charged. •
Driver notification in the instrument cluster
display
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
C Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
engine may be limited. As soon as you start driving again, the
battery will be recharged and the notification will go out.
Driver notification appears and goes out again
If this driver notification appears after the ignition is turned on or
while driving and it goes out again after a while, the battery has
been adequately recharged.
Driver notification appears and does not go out again
If this driver notification appears after the ignition is turned on or
while driving and does not go out again, the battery's state of
charge is not in the optimal range. Starting ability is restricted. Have
the battery checked as soon as possible by an authorized Audi dealer or qualified workshop. •

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
