@ Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­

• Push the lever
c::> fig . 89 -Arrow -c::> ,&.
• Move the steer ing wheel to the desired posi­
t ion.
• Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­
i ng wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you reach the pedals and increase the distance
from the steering whee l.
F or detai led information on how to adjust the
driver's seat, see
c::> page 68.
A WARNING
Improper use of steeri ng wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steer ing whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
- Adjust the driver's seat or steering wheel
so that there is a minimum of 10 inches
(25 cm) between your chest and the
steering wheel
¢ page 99 , fig. 107. If
yo u cannot maintain this min imum dis- tance, the airbag system cannot protect
you proper ly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing wheel is aligned with your

156 Intelligent technology
If starting capability is jeopa rdized due to en­
ergy consumption, a message appears in the
driver information disp lay.
You have to start the engine to charge the
battery.
With the engine running
A lthough electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens most ly when
little energy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased slightly . This is normal and not
a cause for concern . By increas ing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, th is
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge : battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig­
nition is turned on or whi le driving and it goes
out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notif ication appears after the ig­
nition is turned on or while driving and does
not go out again, the battery 's state of charge
is not in the optimal range. Starting ability is
restricted . Have the battery checked as soon
as possible by an autho rized Aud i dea le r o r
qualified wo rkshop.

158 Driving and en vi ro nm ent
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.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
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 highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving 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.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not stop the veh icle, drive in reverse
or switch 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 salt water because
it can ca use corrosion.
-
Catalytic converter
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 ¢ page 17 4,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much motor o il in your eng ine
r::;> page 183, Adding engine oil~-
.. Never try to p ush- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
t h e vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183.
-Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into ..,.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved
by the manufacturer.
- Do not alter or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
