(D Note
When adding flu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur.
® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other ve hicle flu­
i ds, have yo ur vehicle inspected by a n au­
thori zed Audi dea le r.
Closing the engine hood
.,. Pull the hood down un til the pressure from
t he struts is reduced.
.,. Let the hood
drop down and latch in p lace .
Do not try to push it shut; it may fail to en­
gage ¢&_ .
A WARNING
-
A hood that is not completely latched
could fly up and b lock your view while dr iv ­
ing .
-When you close the engine hood, check it
to make sure the safety catch has p roper ­
ly engaged. The hood sho uld be flush
with the surrou nding vehicle body pa rts.
- If you notice while driv ing t hat the hood
is not s ecured prope rly, stop at onc e and
close it.

246 Checking and filling
-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
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.
(D 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
¢ page 204. The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional elec trical 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.
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, other­
wise 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.
- Battery mounts and clamps must always
be secured correctly.
- Read and follow the warnings under
¢ page 243, Working on the battery be­
fore performing any work on the 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 .

of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See
c> page 256 , Tires and vehicle
load limits
for more important information.
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the tires and be sure not to
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your vehicle and in this manual and the kind
of driving you plan to do.
Never exceed the maximum inflation pres­
sure listed on the tire sidewall for any rea­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the tires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the required tire pressure from the tire
pressure label. The tire pressure label is lo­
cated on the driver's side 8-pillar.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the valve .
Tires and wheels 255
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a journey. Do not
forget to check the tire pressure for the spare
wheel
c::;,page 271.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures on all wheels. In addition, you must then
store the new tire pressures in the tire pres­
sure monitoring system*
c::;, page 266 .
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
[I] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat­
ed on a sticker on the driver's side B-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly .
- The use of incorrect tire pressure values
can lead to accidents or other damage .
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
