Applies to vehic les: with defective light bulb warn ing
Defective light bulb warning
The defective light bulb warning monitors the function of
the light bulbs in the vehicle.
The defective light bulb warning monitors the function of the light
bulbs. If a defective light bulb is detected, or if a light bulb has
burned out, a yellow symbol appears as well as a notification that
shows which light bulb is defective.
Defective bulb
If this symbol lights up, a turn signal (front or rear), a headlamp,
a brake light, the back-up light, a fog lamp or a rear fog lamp has
failed.
& WARNING
• Light bulbs are under pressure and can explode when bulbs are
replaced -risk of injury.
• With gas-discharge lamps* (xenon headlights), the high­
voltage component must be handled appropriately. Doing other­
wise poses a risk of death!
[ i] Tips
Have an authorized Audi dealer or other qualified workshop perform
the replacement or the repair. •
Windshield washer fluid level too low ->
Top off the washer fluid
If the symbol illuminates, add windshield washer fluid to the washer
system and also to the headlight washer system* =>

If the symbol lights up, even when there is ample fuel in the tank,
and the text

appears in the display, there is a fault in the system. Contact a qual­
ified workshop to have the fault rectified. •
Applies to veh icles: with battery voltage warning
Battery voltage ..:J
If battery power drops into the range where it can limit the ability of
the engine to start, this the symbol appears in the instrument
cluster display with the following driver message
battery charge
low: Indicates charging by being driven .
While this driver notification is displayed, you have to be prepared
for limited starting capability.
Driver message appears and goes out again
If this driver message 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 message 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 capability is restricted.
Have the battery checked at an authorized Audi dealer or other qual­
ified workshop as soon as possible. •

Fuel supply and filling your fuel tank Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle switches off automatically when the tank is full.
Putting the fuel cap back on
- After filling your tank, twist the fuel cap clockwise as far
as it will go.
- Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel cap properly and completely.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns.
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­ eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.
& WARNING (continued)
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or
empty may leak and could cause a fire, especially in a crash.
• If, under exceptional circumstances, you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable .
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86l.
0 Note
If any fuel has spilled onto the car, it should be removed immedi -
ately to prevent damage to the paint. _.,

in "Worki ng o n the batte ry" on
page 282 .
-Turn off the ign it io n and all electrical consumers . -
Make s ure the area is well ven tilated when y ou charge
the battery .
- Open the eng ine hood =>
page 270.
- Open the red cover on the pos itive pole => fig . 227.
- Connect the charger connectors accord ing to the ins truc-
t ions to the
jump start bolt s. (Bolts under the red cover=
"positive", Bolts with hex head= "negative").
- Only now pl ug the mains lead for t he charging equi p­
me nt in to the wa ll ou tlet and turn i t on =>& .
-Make sure the ch arging rate is not over 30 amp s/14.8
Volt .
-When the battery is fully charged: Turn the charging
equipment off and remove the mains lead from the wall
outlet .
- Now remove the clamps for the charging equipment .
- Close the red cover on the positive pole.
- Close the hood
=> page 271 .
A d ischarged battery can freeze at temperatures of only 32 °F (0 °C).
Allow a fro zen bat tery to thaw completely befor e attempting to
cha rge it=> & . However , we recommend not using a thawed battery
again because the ba ttery c asing can be cra cked due to ice forma ­
tion and can leak battery acid .
Batt ery c harg ing ( Max imum cha rg ing r ate of 3 0
amp s/14.8 Volt )
When charging at
/ow voltages (e .g . with a trickle c harger ), the
battery cables do not have to be disconnected first . The battery caps
should
not be opened when cha rging a battery .
I t is not necessary to remove the battery from the luggage compart -
ment. _..

Fast charging the battery {charging rate above 14 .8
Volts )
For technical reasons do not use a battery charger that uses vo ltage
greater than 1 4.8 Vo lts to charge y our ve hic le 's battery.
& WARNING
Charging a battery can be dangerous .
• Always follow the operating instruct ions provided by the
battery charger manufacturer when charging your battery.
• Never charge a frozen battery. It may explode because of gas
trapped in the ice . Allow a frozen battery to thaw out first.
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze .
• Charge the battery in a well ventilated area. Keep away from
open flame or electrical spark . Do not smoke . Hydrogen gas gener ­
ated by the battery is explosive.
• To redu ce the danger of e xplos ion , never connect or disconnect
charger cables while the charger i s operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment.
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .

& WARNING !continued)
• Before you check anything in the engine compartment, always
read and heed all WARNINGS~ page 263, "Engine compartment".
0 Note
• Applying a higher voltage booster battery will cause expensive
damage to sensitive electronic components, such as control units,
relays, radio, etc .
• There must be no electrical contact between the vehicles as
otherwise current could already start to flow as soon as the positive
(+) terminals are connected.
[ i) Tips
• The discharged battery must be properly connected to the
vehicle's electrical system. When jump starting or charging the
battery , never connect the negative ground cable to the battery
negative post because the battery manager system must be able to
detect the battery's state of charge. Always connect the negative
ground cable to the negative ground post of the battery manager
control unit .•
Use of jumper cables
Make sure to connect the jumper cable clamps in exactly
the order described below!
