Fuel and Refueling
Gasoline additives
A major concern among many auto manufactur
ers is carbon deposit build-up ca used by the type
of gasoline you use .
Although gasoline grades d iffer from one manu
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ital engine
parts, such as fuel injectors and intake valves. Al
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas
oline. For more information on TOP TIER Deter
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon depos its can rob your en
g ine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi
cle Limited Warranty .
- Do not add aftermarket fuel additive prod
ucts to yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel f iller flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc
tions see
c> page 190 .
You can find the fuel tank capacity of your vehicle
in
<=>page 242 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in
formation about fuel specifications , see
<=> page 186 .
Your veh icle fuel tank has an on-board refuelling
vapor recovery system. This feature he lps to pre
vent fuel vapors from escaping from the tank and

polluting the environment whi le you refuel your
veh icle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car
ry additional fuel containers in your car. Gas
can isters and other containers used to trans
port fue l can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a col lision.
If you must transport fuel to
use for your lawn mower , snow blower , etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer
tain the container meets industry standards (ANSI/ASTM F852 -86) .
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.

~ Open the cover on the positive pole ~ fig. 165.
~ Connect the charger connectors accord ing to
the instructions to the
jump start bolts. (Bolts
under the cover= "positive", Bo lts with hex
head = "negative") .
~ Only now plug the mains lead for the charging
equipment into the wall outlet and turn it on
~ & -
~ Make sure the charging rate is not over
30 amps/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 equip-
ment.
~ Close the cover on the posit ive pole .
~ Close the hood ~ page 191.
A discharged battery can freeze at temperatures
of only 32 °F (0 °C) . Allow a frozen battery to
thaw completely before attempt ing to charge it
~ & . However, we recommend not using a
thawed batte ry again because the battery casing
can be cracked due to ice formation 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 trick
le 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 compartme nt.
Fast charging the battery (charging rate
above 14.8 Volts)
Fo r techn ical reasons do not use a battery charg
e r that uses voltage greate r 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 manufactur
er when charging your battery .
Checking and Filling
-Never charge a frozen battery . It may ex
plode because of gas trapped in the ice. Al
low 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 generat
ed by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing 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 w ith a solution of
warm water and baking soda to neutralize
the acid .
@ Note
Never use a fast charger as a booster to start
the engine . This will seriously damage sensi
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
cha rge r.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
r esponsib le for distr ibut ing the electrical energy
throughout your vehicle ~
page 175. The intelli
gent energy management system will keep the
engine battery charged better then vehicles with
out this system. To make sure the additional
electrical energy 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
t ime your vehicle was delivered) . Specifications
are listed on the battery housing . Your author
ized Audi dealer must code the battery in the en-
ergy managemen t system to enable you to use
