General information
Your vehicle is equipped with a electronically controlled continuously
variable transmiss ion (multitronic ®). Inside the multitronic ® system,
the gear ratios are not shifted in finite steps as in a conventional auto­
matic transmission, but rath er
continuously. As a result, engine
power is applied smoothly and comfortably, and better fuel economy
is achieved .
The transm ission selects the appropriate gear ratio (upshifts and
downshifts) automatically based on set driving programs
~ page 156, "Dynamic shift program (DSP)".
You can also manually select a shift program (tiptronic ®)
~ page 157.
You should note, that the multitronic transmission differs from a
conventional Autom ati c Transmission . In the multitronic transmis­
sion the engine power is transferred via a link-plate chain, rather than
by a conventional torque converter. The multitronic transmission
greatly reduces vehicle "creep" when at a standstill and the transmis­
sion is in

Intelligent technology
'-------------------------------------------------
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
red uces 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 adjust­
ment, may not be avai lab le. The convenience functions wi ll be ava il­
able 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 o r
use other MMI functions, the battery is being discharged.
If starting capability is jeopard ized 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 wis h to continue using the funct ions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
dr iven, 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
req uire especially large amounts of energy are temporarily cut back
or switched off . H eating 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 ava ilable again as soon as
the energy ba lance 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 addit ional energy required is generated and the
battery is charged. •
Driver notification in the instrument
cluster display
If battery powe r drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
w ith the following driver message:
1 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
eng ine 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
wh ile 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 dr iver not ificat ion appears after the ign it ion is turned on or
whi le 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 at a dealership.

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). .,

Brake fluid will damage the paint of your vehicle.
Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating condit ions, the battery in your Aud i does not
need any maintenance. With
high outside temperatures or long daily
drives we recommend that you have the electrolyte level checked by
a service facility. The electrolyte level should also be checked each
time the battery is charged~
page 292.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 211.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in. To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of severa l 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 249.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func­
tions will be available again when you turn on the ign ition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are used more often .
Avoid unnecessary power consumpt ion, particu larly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before w inter sets in
=> page 292. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longe r.
(I] Tips
If your veh icle is left standing for several weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced.•
