- Now press the interlock and move the selector lever to
the
N position .
The selector 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 lock ing device .

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
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.
• 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). .,

Battery
General information
Under normal operating condi tions, the battery in your Audi does
not need any maintenance. With
high outside temperatures or long
daily drives we recommend that you have the e lectrolyte level
checked by an au thorized Audi dealer or qualified workshop . The
e lectrolyte level should also be ch ecked each time the battery is
charged ~
page 344.
Have the battery checked when you take your vehicle in for service .
Yo u are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag dep loyment, the battery is discon ­
nected from the vehicle electrical system for safety reasons~
& in
"Repair, care and disposal of the airbags" on
page 255.
Disconnecti ng th e batt ery termin als
Some vehicle functions (power window regulators , for example) are
lost if the battery termina ls are disconnected. These functions 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 sys tem when abso lutely necessary for repairs .
Vehicles not driven for long per iods
If you do not drive your vehicle ove r a period of several days or
weeks, electrical components are gradually cut back or switched off .
T his reduces energy consumption and maintains starting capab ility
over a longer period
~ page 295 .
Take i nto consideration that whe n you u nlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustme nt, may not be ava ilable. The convenience
functions will be available again when you turn on the ignition and
start the engine .
Wint er op erati on
Duri ng the winter mont hs, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le star tin g, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particular ly in city traffic or
when trave li n g o nly short dis tances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
~ page 344. A we ll cha rged battery w ill not only preven t starting
problems when the weather is cold, but will also last longer . ..,_
