Storage
General overview
There are numerous places to store items in your vehicle.
Glove compartment => page 89
Storage compartment in the roof =>
page 89
Coat hooks => page 89
- -Storage in the trim panels in the luggage
compartment
& WARNING
• Always remove objects from the instrument panel. Any items
not put away could slide around inside the vehicle while driving or
when accelerating or when applying the brakes or when driving around a corner .
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake, depress the clutch or accelerate.
• Any pieces of clothing that you have hung up must not interfere
with the driver's view. The coat hooks are designed only for light­
weight clothing. Never hang any clothing with hard, pointed or
heavy objects in the pockets on the coat hooks . During sudden
braking or in an accident - especially if the airbag is deployed -
these objects could injure any passengers inside the vehicle . •

The climate controls are a combination of heating, ventilation and
cooling sys tems, which automa tica lly reduce humidity and cool the
air inside your vehic le .
The climate contro l automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatica lly adjusted. The
system also takes into account strong sunsh ine so that manual
adjustment is not necessary . So in almost all cases,
a ut oma tic mode
offers the best co nditions for the comfort of the occupants at all
times of the year~
page 99.
Please note the following :
Turn on the air conditioner to reduce hum idity in the veh ic le. This
a lso prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
c onden sation from the evaporator may drip under the vehicle . T his
is normal and does no t indicate a leak.
If the outside temperature is low, the fan norma lly on ly switches to
a higher speed once the engine coo lant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from a standstill using fu ll throttle to save engine power .
The compressor also switches off if the coolant temperature is too high, so that the engine can be adequately cooled under extreme
loads.
Du st and poll en filte r
The dust and pollen filter (a combined particle filter and activated
cha rcoal fi lter) reduces or prevents outside air pol lut ion (dust, or
pollen) from entering the vehic le .
The dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can prop­
erly work .
I f you drive your vehicle in an area with a high degree of a ir pollu­
tion, the filter may need to be changed more frequent ly than speci-

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.

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 not ification in the instrument cluster
d isplay
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:
'-' 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. •

Checking and filling IJI
--------------~-
•
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 of automatic transmission to "P" (Park);
put manual transmission in Neutral .
• 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.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
