ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
•
Closing the engine hood
- Pull the hood down until the pressure from the strut 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
=> & .
• I I • • I
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key .
• Apply the parking brake.
• 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

For example, a charging current of 4.5 amps would be used on a
battery rated at 45 Ah. Rated capacity of the battery in your vehicle
is listed on the battery housing .
The battery caps should
not be opened when charging a battery.
& WARNING
Charging a battery can be dangerous.
• Always follow the operating instructions 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 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 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.
0 Note
Never use a fast charger as a booster to start the engine . This will
seriously damage sensitive electronic components, such as control
units, relays, radio, etc ., as well as the battery charger. •
Disconnecting and connecting the battery
When the battery is disconnected some features on the
vehicle will become inoperative and you must reset them
when the battery is reconnected.
When you disconnect the vehicle battery note the following:
• some data stored in the driver information system is erased,
• the clock stops,
• the factory installed radio locks up,
• the engine management system and the one-touch-up and one­
touch -down functions of the power windows no longer work .
After you reconnect the battery, you must reset the following
features :
Inoperative because the
battery was discon­
nected:
clock
one-touch-up and one-touch­
down feature on the power
windows
engine management
seat memory*
radio station coding
Removing battery
To reset after the battery is
reconnected, see:

___ T_ ir_e _ s_ a_ n
_ d_ w_ h_ e_ e_ls _________________________________________________ _
The tire pressure label on your Audi lists the recommended cold tire
inf lation pressures for the new, original equipmen t tires that were
on your vehic le at the time it was manufactured . For the location of
the
labe l=> page 297, fig. 217 .
Most tires lose a ir natural ly over time. They can a lso lose some air if
you drive over a potho le or hit a curb wh ile parking. It is usually not
possible to see whether the radial t ires used today are under inflated
just by looking at them.
Therefore, be su re to check tire pressures at least once a month and
always before going on a long trip . Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you wou ld not cons ider to be
" long ."
See => page 301, "Tires and vehicle load limits" for more
important i nformation .
A lways use an accurat e tire pressure gaug e when checking and
adjusting inflat ion pressures. Check a ll of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the t ire is "cold," let air o ut of the t ire slowly with the edge of the tire
gauge and keep check ing the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you p lan to do .
I f the pressure in any tire is too low, note the difference between the
pressure in the co ld 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) fo r the t ires on your veh ic le as listed on
the on your vehicle and in this manual and the kind of driving you pl an to do .
Never exceed the m aximum inflation pressure li sted on the tire
s idewall for an y re ason .
Remem ber that the vehic le manufacturer, not t he tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
I t is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the t ire pressure label
located either on driver 's side B -pillar or inside the fuel fi ller flap . •
Turn the va lve stem cap counter -clockwise to remove it from the
t ire valve .
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The s lightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstal l the va lve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is especially important at high spe eds . The
pressure should the refore be checked at least once a mo nth and
a lways before starting a journey. Do not forget to check the tire pres ­
sure for the spare whee l
=> page 317.
Wh en should I adjust th e tir e pre ssur es?
Adjust t he tire pressure to the load you are carry ing . After changing
a wheel
o r replacing whee ls you have to ad just the tire pressures on
a ll whee ls . In addition, on vehicles w ith tire pressure monito ring
system* you must then store the new tire pressures in the system
=> page 45.
& WARNING
Incorrect tire pre ssure s and /or underinflation can lead sudden tire
f ai lure , loss of control , collision , seri ous per sonal injury or even
death.
• When the w arning symbol
(l) appe ars in the in strument
clu ster , stop and inspect the tire s.
• Incorrect t ire pres sure and /or underinflat ion can cause
increa sed tire wear and can affect the handling of the vehicle and
s topping ability.
• Incorrect tire pres sures and /or underinflation can also lead to
s udden tire fa ilure , inc luding a blowout and sudden defl ation ,
cau sing los s of vehicle control .
