@ Tips
-The oil pressure warning display. i s
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
structions about how to measure oil con­
sumption accurately.

(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system .
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth ­
erwise it will be damaged and will then
have to be replaced .
- When opening the doors, the windows
lower approximately 10 mm automati­
cally. This function is not available when
the battery is disconnected, which
means there is a risk that the door seal
or the window could be damaged.
Battery charging
Starting the engine requires a well charged
battery.

A discharged battery can
freeze at tempera­
tures of only 32 F
0 (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to
charge it
c::> ,& . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma­
tion and can leak battery acid.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt)
When charging at
low voltages (e .g. with a
trickle charger), the battery cables do not
have to be disconnected first. The battery
caps should
not be opened when charging a
battery .
It is not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to disconnect the cables .
Fa st charging the battery (charging rate
above 14.8 Volts)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
-Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a frozen battery.
It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may
have
