.,&_ WARNING
-When you leave your vehicle - even if on­
ly briefly - always take the ignit ion key
with you. This applies particularly when children remain in the vehicle. Otherwise
the children could start the engine or op­
erate electrical equipment (e.g. power
windows). The power windows are func­
tional until the driver's door or passeng­
er's doo r has been opened.
- Be careful when closing the w indows.
Check to see that no one is in the way, or
serio us injury could result!
- When locking the vehicle from outside,
the vehicle must be unoccupied since the
windows can no longer be opened in an
emergency .
{D Tips
-When you open the doors, the windows
automatically lower abo ut 10 mm.
- When the window in the driver's or pas­
senger's door is complete ly open, it will
raise approximately 25 mm when the
door is opened. The window will lower
again when you close the door.
- After the ignition has been switched off,
the windows can sti ll be opened or
closed for about 10 minutes. The power
windows are not switched off until the
dr iver's door or passenger's door has
been opened .
What to do after a malfunction
The one-touch open and close function must
be reactivated if the battery has been discon­
nected.
.. Pull and ho ld the power window switch until
the window is fully closed. .-

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­ ing through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh sa lt water because
it can ca use corrosion.

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv­
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini­
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity once
they have warmed up.
The cooli ng fan can cont inue to run in your ve­
hicle after the engine is switched off . Howev­
er, driving the veh icle to coo l it down is pa rti c­
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
"' Always use lead-free gasoline c:> page 208,
Fuel supply .
"' Never run the tank down all the way to emp­
ty.
"' Never put too much mo to r o il in yo ur eng ine
c:> page 218, Adding engine oil "t:::r..
"' Never try to push -or tow -start you r vehicle .
T he catalytic co nve rter is an efficient "clean ­
u p" dev ice bui lt into t he exhaus t system of
the ve hicle . The cata lytic converter bu rns
many of the pollutants in the exha ust gas be ­
fore they are re leased into the atmosphere.
T he exclus ive use of unleaded fuel is c ritical ly
i mportant for the life of the catalyt ic convert -
er and proper functioning of the engine .

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depend ing upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating . If you anticipate what is go ing to
h appen next, you will need to b rake less and,
thus, accelerate less. Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t tr affic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fuel consumption, exhaust emissions and en­
g ine no ise increase d ispropo rtionately at high
speeds. If you dr ive at approxima tely three
q uarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
~ S hu t the engine off when you a re not dr iv ing
t h e vehi cle.
Dri vin g and en vironm ent 201
~ Do not warm up the vehicle by lett ing the
engine run at id le .
It makes sense to shut off the engine in traffi c
jams, when wa it ing fo r tra ins to pass at rail ­
road crossings, or at traffic lig hts that have
long waits on red. T urning the engine off for
just 30-40 seconds saves more fuel than is burned start ing the e ngine again.
It takes a long time for the engine to warm up
fully when it is runn ing at id le. However, wear
and noxious emissions are especia lly high
when the engine is warm ing up. So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up .
(D Note
Do not leave engi ne idling unattended a f­
ter start ing . If warning lights sho uld come
on to i ndicate improper operat ion, they
would go unheeded. Extended idling a lso
p rodu ces hea t, w hich could re sul t in ove r­
hea ting or othe r dam age to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
~ Have your ve hicle serviced at reg ula r i nter-
vals.
By having your veh icle regula rly serviced by an
Audi deal er he lps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affec ts its sa fe ty and ability to
hold its value, it also affects
fuel con sump­
tion .
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to eng ine
load and speed.
It is normal fo r th e oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven .
