sistance if necessary .
If the engine coolant level is correct, then the
radiator fan may be the cause of the malfunc­
tion .
• Coolant temperature too high! Please let
engine run with vehicle stationary
If the indicator light turns on and the mes­
sage appears in trailer mode*, let the engine
run at idle for a few m inutes to cool down.

222 Fuel su ppl y and fillin g yo ur fu el t an k
- For your safety , we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, 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 portab le fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­ n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle complete­
ly 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 dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full . Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol­
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not ind icate the correct fuel
level after refuelling .
- Diesel vehicles* are equipped with a die­ sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au­
thorized repair facility for assistance.
- The fuel fi ller f lap of your vehicle is not
locked when you lock the vehicle from
the inside.

(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 t he battery from "freezing", oth­
erwise it w ill be damaged and w ill then
have to be replaced .
- When opening the doors, the w indows
lower approx imately 10 mm automati­
ca lly. This function is not available when
the battery is disconnected, wh ich
means there is a ris k tha t the door seal
or the w indow cou ld be damaged.
Battery charging
Starting the engine requires a well charged
battery.

A discharged battery can freez e at tempera­
tu res of only 32 F
0 (0 °C). Allow a frozen bat­
te ry to thaw completely before attempting to
c h arge 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.
Batt ery cha rging (Ma ximum charging rat e
of
30 amp s/14.8 Volt )
When charg ing at low vo ltages (e .g. with a
trickl e cha rge r), the battery cables do not
have to be disconnected first. The battery
caps should
not be opened when charg ing a
batte ry.
It is not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to d isconnect the cables .
Fast ch arging the battery (ch arging rate
ab ove 14 .8 V olt s)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
_&. WARNING -
Charging a battery can be dangerous.
- Always follow the operating instructions
p rovided by the battery cha rger manu­
facturer when charg ing your battery.
- Never charge a frozen battery . It may ex­
p lode because of gas trapped in the ice.
A llow a fro zen ba ttery to thaw ou t firs t.
- D o not reuse batteries wh ich wer e fro-
z en. The ba ttery housing may have .,..

cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip ­
ment .
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
0 Note
Never use a fast charger as a booster to
start the engine . This will seriously dam ­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
q page 202. The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and manu ­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery housing. Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replacing the battery.
Checking and filling 241
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and plug sealing.
When installing the battery, make sure the ig ­
nition and all electrical consumers are switch­
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and lead and must always be disposed of prop­
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi­
ronment.
