Adjusting the steering wheel column
The steering wheel position can be continu­
ously adjusted in height and distance.
Fig. 81 Lever under the stee ring column
• Push the lever¢ fig. 81 -Arrow- ¢,&. .
• Move the steer ing wheel to the desired posi ­
tion.
• 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
ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detailed information on how to adjust the
driver's seat, see
¢ page 62.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle 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 93, fig. 101. If
you cannot maintain this minimum dis­
tance, the airbag system cannot protect
you properly.

-If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equipment is ava ilable .
- If the steering wheel is aligned with your
face, the supplemental dr iver 's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering wheel is al igned with your
chest .
-Always hold the steer ing wheel w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag deploys .
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

(D Note
Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
@ Tips
Clean the spoiler compartment every 2 to
3 months . The spoiler compartment must
always be free of ice, snow, leaves or other
debris.
Braking
General information
What affects braking efficiency?
Oper ating condit ions and d riving hab it s
T he brakes on today's automobi les are st ill
s ubject to wear, depending largely on opera t­
ing conditions and dr iv ing habi ts
c> & . On
vehicles that are e ither driven mostly in stop ­
and-go city traffic or are d riven hard , the
b rake pads should be checked by you r author­
i zed Audi dealer more often than specified i n
the
Warr ant y & Maint enan ce booklet . Failure
to have your brake pads inspected can res ult
in red uced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the eng ine. This way, you p revent un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not hold the brakes
down continuously. Pump th e brakes at inter­
vals.
Noises may occur when braking d epending on
the speed, braki ng force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Unde r certain conditions, for example, w hen
driving through water or ve ry heavy rain, or
even after washing your vehicle, the braking
effect can be reduced d ue to moisture (or in
fre ezing conditions ice) on the brake pads . A
few ca utious brake applicat ions should dry off
the b rake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when th e vehicle is driven on a salt-covered
Int ellig ent technolog y 145
road and the b rakes are no t used. Likewise ,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap ­
plications of the brake
c> & .
Cor ro sion
T here may be a tendency for dir t to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
on ly fo r short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed
c> & .
Faults in the brak e syst em
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have fai led
c> & .
Low brake fluid lev el
Malfunctions can occur in the brake system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake booster
T he brake booster inc reases the pressure that
you generate with the brake peda l. It works
o nl y when the engine is running
.c> &
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for t his in­
spection

aware of when changing a tire? .
A WARNING
--=
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower

gear or lower driving range. Do no t ride
t h e brakes or hold the pedal down too
long or too often. This cou ld cause the
bra kes to get hot and dimin ish braking
efficiency .
- Do no t "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the brakes to
overheat, prematu re wear and inc reased
stopp ing distan ce.
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving i n heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be red uced . In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake d iscs and pads w it h a few cautious
brake appli cat ions.
- If you damage the fro nt spo iler, or if you
ins tall a different spoiler, be su re the air
flow to the fron t bra kes is not o bstr uct­
ed. O therwise the brake system co uld
overheat reducing the effectiveness of
the entire brake system.
- F ailure o f one bra ke c ircuit will impair
the b raking capability resulting in an in­
creased stopp ing distance . Avoid driv ing
the vehicle and have it towed to the near­
est Aud i dea le r o r qualified workshop.
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not working, t he
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance . Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assi st is electronically
matched to vehicle speed .
T he power steering system assists the driver
so that he can steer the vehicle with reduced
physical effor t.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn.
A WARNING
If the system develops a problem , you
must seek qualified profess iona l assis ­
tance .
(D Note
-
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onge r proportionate to the vehicle speed .
This is most not icea ble whe n tu rni ng the
s tee ring w heel a t low speeds (fo r example
when pa rking), -more effort w ill be re­
q uired than us ua l.
- Be aware o f the diffe rent than usual
steering response and adjust your steer ­
ing force acco rdingly.
- Have the problem checked and set right
by an autho rize d Aud i dealer as soon as
possible.
- If a s teer ing mal func tion occurs, this is
signa led wit h the

lights and a warning tone, see.
(D Tips
- If the powe r stee ring system sho uld fai l,
or if the engine is not ru nning (fo r exam­
ple, whi le being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.

off. These systems will be avai lable again as
soon as the energy ba lance has bee n restored.
You will also notice that engine idle speed has
been increased s lightly. This is normal and not
a cause for concern. By increasing engine idle
speed the additiona 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 lim it the ab ility of the engine to start, th is
i s shown in the inst rument 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 l imited. As
soon as you start driving aga in, the battery
w ill be recharged and the notification will go
out.
Driver notification appears and goes out
again
If th is driver notification appears after the ig­
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig­
n ition 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
restr icted. Have the battery checked as soon
as possible by an author ized Audi dealer or
qualified workshop.

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 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 higher 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 of 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 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 s top 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 sa lt water because
it can cause 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 161 ,
Fuel supply.
.,. Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
c:::> page 170, Adding engine oil 9::71 .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
the 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
important for the life of the catalyt ic convert­
er and prope r fu nct 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 materia l wh ich can
cause a fire .
- Do not apply additional undercoating or
rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire .
(I) Note
-Be aware that just one tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed the correct eng ine oil level
c:::> page 170.
- Do not drive until the fue l tank becomes
completely empty . The engine could m is-
fire. Unburned fuel could also get into

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
""Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions 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 improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over-
Driving and environment 153
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer helps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could 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 shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .
