& WARNING
Be awa re: The engine compartment of any motor vehi cle is a
potentially hazardou s area.
• Before working in the engine compartment , be sure to read the
information
::::> page 26 3.
• Before reaching into the front p lenum panel, always remove the
ignition key . Otherwise , the w ind shield wiper sy stem cou ld unin ­
tentionally be sw itched on, pos sibly causing personal in jury from

21 Us e on ly th e correct c lean ing solut ions. N ev er use gasolin e or di esel fuel.

<£> For the sake of the environment
As soon as the correctly operated nozzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addition, the expansion space in the fuel tank
will be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i] Tips
• Running your engine while refuelling may cause vapors to
escape or even cause fuel to spill out of the tank. This would then
shut off the fuel nozzle before the tank is full.
• Do not refuel your vehicle with the ignition turned on. The fuel
gauge may otherwise not indicate the correct fuel level after refuel ­
ling .
• The fuel filler flap of your vehicle is not locked when you lock the
vehicle from the inside .•
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.

Checking and filling IJI
--------------~-
•
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 .
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral .
• 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: ..,

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 airbag deployment, the battery is discon­ nected from the vehicle electrical system for safety reasons=>
& in
"Repair, care and disposal of the airbags" on
page 202.
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 again . To
prevent this, the battery should only be disconnected from the
vehic le electr ical system when absolute ly necessary for repairs .
Vehicles not driven for long periods
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 reduces energy consumption and maintains starting capability
over a longer period=>
page 241.
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
functions will be available again when you turn on the ignition 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 consumption, particularly in city traffic or
when traveling only short distances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=>
page 284 . A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i ] Tips
If your vehicle is left standing for several weeks at extremely 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. •
Working on the battery
Be especially careful when working on or near the battery.
The battery is located in the luggage compartment under
the floor. Before you check anything in the luggage
compartment,
read and heed all WARNINGS =:>& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury.
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
Always wear eye protection .
Battery acid contains sulfuric acid. Always wear
gloves and eye protection.

• To ensure a proper TPMS function use AUDI Original Tires which
are marked with "AO" or "RO" on the tire sidewall. =:>
page 299.
• The tire pressure monitoring system on your Audi was calibrated
using tires with the "AO" or "RO" identification. We recommend
using these tires.•
Applies 10 vehicles: with tire pressure monitor ing sys tem
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are rotated or
changed, the TPMS must be reset via radio or MM/ *.
-Turn on the ignition.

Before resetting the TPMS, the current pressures of all four tires
must correspond to the specified values. Adjust the tire pressure
and reset the pressure in the tire pressure monitoring system
according to the load you are carrying =:>

any modifications.
This will he lp ensure that vehicle function, performance and safety
are not impaired ~& .
Attempting to work on e lectronic components and the software
used with them can cause malfunctions. Because of the way e lec­
tronic components are interconnected with each other, such
malfunctions can also have an adverse affect on other systems that
are not directly involved . This means that you risk both a substantial
reduction in the operational safety of your vehicle and an increased
wear of vehicle parts~& . Authori
zed Audi dealers will perform this work in a professiona l and
