- Move the selector lever into P or N
~ &.
- Turn the ignition key to position @~ fig. 132 -do not
depress the gas pedal when starting the engine.
A cold engine may sound loud after it has been started. This is due to
the hydraulic valves building up oil pressure. This is normal and is not
a need for concern.
If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later .
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide , a color
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft .
0 Note
• Avoid high eng ine speeds, fast accelerat io n or heavy engine loads
wh ile the engine is still cold. This could damage the engine.
• The engine cannot be started by push ing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions,
do not let your vehicle stand and warm up. Be ready to drive off imme
diately after starting your vehicle. Maintain moderate speed unti l the
engine is completely warm. Remember, the engine performs best at
operating temperature .•

ment Safety first Vehicle operation
& WARNING
•
You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping di stan ce.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads , linings, discs and drums .
Carefully apply brakes for a test . Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect braking efficiency. Clean
off accumulated salt coating from brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective
ness of the entire brake system .
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance . Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•

Driving and environment
New brake pads
Remember that new brake pads do not have a f ull braki ng
e ff e ct during the first 250 miles (400 kilometers) after they
are i nsta lle d.
New bra ke pads have to be "burnished in" before they have opt ima l
grab=> &.
Dur ing the break -in period, you sho uld avoid putting severe loads on
the brakes. Severe loads incl ude, for example, sudden hard braki ng,
in particu lar at very high s peeds or, for examp le, on mountai n passes.
& WARNING
New brake pads don 't have the be st stopping power and must be
" broken -in " during the initial 100 to 150 miles (150 to 200 kilo
meters ) of normal cit y driving. You can compensate for thi s by
pressing th e brak e pedal more firmly. This also applies lat er wh en
new pad s are installed. n
Catalytic converter
It is very important that your emissio n contr ol system
(catalytic converter) is functioning prop erly to ensure
that your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline==> page 283, "Fue l su pp ly" .
- Never ru n the tank down a ll th e way to empty .
- Never put too m uch motor oil in your engine==>
page 294,
"Adding engine o il
The catalytic converter is an efficient "clean- up" device bu ilt into the
exha ust syste m of the ve hicle. The cat alytic converte r burns many of
the polluta nts in the exhaust gas before they are released into the
atmosphe re.
Th e e xcl usive use of unleaded fuel is cr itic ally important for the life of
the catalytic converter and proper f unction ing of the engine.
& WARNING
• Do not park or operate the vehicle in areas whe re the hot
exhaust sy stem may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or ru stproofing on or
near the exhaust manifold , exhaust pipes, catalytic conve rter or
heat shield s. During driving, the substance used for undercoating
could overheat and cause a fire .

could lead to damage.
<£> For the sake of the environment
Even when the Emiss ion Contro l System is operating properly, the
exhaust gas can have a sulfur-like exhaust gas sme ll under some
operat ing states. This depends on the s ulfur content of the fue l being
used. Using a differe nt brand of fuel may help, or filling the tank with
lead-free supe r grade gasoline. •
Avoid damaging the vehicle
When you are dr iving on poor roads, or ove r cur bs, steep r amps, etc.,
make certain that low-lying parts such as spoilers and exhaust system

N ote the following to avoid vehicle damage w hen driving through
water, fo r examp le on flooded roads:
• The water must not be any higher than the bottom of the vehicle
b ody.
• Do not drive faster tha n walking speed.
& WARNING
After driving through water , mud, slush , etc. , the brakes may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to restore the full braking effect.
