release for selector
lever
The emergency release is located under the insert for the
ashtray.
- Press the button next to the cigarette lighter~
page 159,
fig. 174. The insert rises from its holder and you can
remove it.
- Press the white switch down with a pen and hold it down
~ fig. 175.
- Now press the interlock and move the selector lever to the
N position.
The selec tor lever can only be moved from the P position if the igni­
tion key is in the lock and the ignition is turned on. If the vehicle has
to be pushed or towed if the power supply fails (e .g . battery is
discharged), the selector lever must be moved to the N position using
the emergency locking device.•

vidual components. It regulates consumption, so that more electrical
ene rgy 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 259, "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 tra ffic
and during the cold time of year. Abundant electrical energy is
required, bu t on ly 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 prec isely 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.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key, the remote
control or the power seat adjustment. The convenience functions will
be available aga in when you turn on the ignition and start the eng ine.
Controls and equip­
ment Safety first Vehicle operation
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 capab ility 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 dea l consumed and
the battery's state of charge is not optimal.
T o 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 w ill be ava ilable 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 the battery's state of charge is not in the optimal range, this driver
no tifi cation appears in the instrument cluster display:
Low battery charge: battery will be charged while driving ~

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.
Safety first
& 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.
• 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
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch:
-Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running:
- First, fully apply the parking brake, move selector lever to
"P" (Park). .,

a service facility . The electrolyte level should also be checked each
time the battery is charged =>
page 303.
Have the batte ry checked when you take your vehicle in for serv ice .
You are well advised to rep lace a battery that is older than 5 years.
With certa in types of a irbag deployment, the ba ttery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 220.
Di sconne cting th e bat tery t ermina ls
Some vehicle f unct ions (power window regulators, fo r example) are
lost if the battery termina ls are disconnected . These functions have
to be re learned after the battery termina ls are connected aga in. To
prevent this, t he battery should only be disconnected from the
vehicle e lectr ica l system when absol ute ly necessary for repairs.
Vehicles not driven for long periods
If you do no t dr ive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. Th is
red uces e nergy consumption and main tains sta rt ing capabili ty ove r a
longer period=>
page 258.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key*, the remote
control or the power seat adjustment. The convenience functions will
be availab le aga in whe n you tur n on th e ignition and start the eng ine.
Winter operation
Dur ing the winter months, battery capac ity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear w indow defogger, etc., a re
used more often.
Avoid unnecessa ry power consum ption, part ic ula rly i n city traffic o r
when traveling only short distances. Let your authorized Audi dealer check the capacity of the vehicle battery before w inter sets in
=>
page 303 . A well charged battery will not only prevent start ing
prob lems when the wea ther is cold, but will also las t longe r.
Vehicle OP-eration
(I) Tips
If your vehicle is left standing fo r seve ral weeks at extremely low
temperatures, the vehicle battery should be removed and stored
w here it will not free ze. This will preven t it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the
battery.
