steering  column  will  continue  moving as 
l ong  as you are pressing the  switch. 
There must  be at  least  10  inches (25  cm)  be
tween  your  chest  and the  center  of  the  steer 
ing whee l. 
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  steer ing wheel. 
For detai led information  on how to  adjust  the 
driver's  seat,  see 
<::> page  51 . 
In vehicles with  the  memory  f unction* , the 
steering  column  settings  are stored  together 
with  the  seat  position. 
A WARNING 
Improper  use of  steering  wheel  adjust
ment  and  improper  seating  position  can 
cause se rious  personal  injury. 
- Adjust  the  steer ing whee l column  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  the re is a min imum  of  10 inches 
(25  cm)  between  your  chest and the 
steering  wheel ¢ 
page  124,  fig.  131. If 
you can not  maintain  this  min imum  dis
tan ce, the  airbag  system  cannot  protect 
yo u properly. 
- If  phys ica l limitations  prevent  you from 
sitting  10  in ches (25  cm)  o r more  from 
the  steering  wheel,  check with  yo ur au
tho rized Aud i dealer  to  see  if adaptive 
equipment  is availab le . 
- If  the  steering  wheel  is aligned  with  you r 
face,  the  supp lemental  driver's  airbag 
cannot  provide  as much  protect ion  in an 
acc ident.  A lways make sure that  the 
steering  wheel  is aligned  with  your 
chest. 
- Always  hold  the  steering  wheel  with  your 
hands at  the  9 o'clock  and  3 o'clock  posi
t ions to  reduce the  risk  of  pe rsonal  injury 
if  the  d river 's airbag  deploys. 
- Never hold  the  steering  whee l at  the  12 
o'clock  posit ion or w ith  your  hands  i nside  the  steering  wheel  rim  or  on the  steering 
wheel  hub.  Hold
ing the  steer ing wheel 
the  wrong  way can cause serious  injuries 
to  the  hands, arms  and  head  if the  driv
er 's airbag  deploys.

Operating  conditions  and  driving  habits 
The brakes on today's  automobiles  a re still 
subject  to  wear,  depending  largely  on operat i ng co nd it io ns and driving  habits ¢,& . On ve
hi cles that  a re e it h er  dr iven most ly in  stop
and-go  city  t raff ic or  are dr iven hard,  the 
br ake  pa ds  should  be  check ed  by yo ur au thor
iz ed Audi  dea ler  m ore often  th an spec ified  in 
the 
Warranty & Maintenance booklet. Failure 
to  have yo ur  brake pads ins pected  can result 
in  reduced brake performance . 
On stee p slopes, you  sho uld use  the br aking 
e ff ect o f the  engine.  This way, you  prevent  un 
necessary wear  on t he brake system.  If  you 
must  use your  bra kes, do not  hold  the  brakes 
down  cont in uous ly. Pump the  brakes at  inter
vals. 
Moisture  or  road salt 
U nder certa in conditions,  for  exam ple, when 
driving  th roug h water  or very  heavy rain,  or 
even after  washing  your  veh icle , the  b raking 
effect  can be reduced due to  m oist ure (or in  ..,.

freezing  conditions ice) on the  brake pads. A 
few  careful  brake applications  should  dry  off 
the  brake pads or  remove  any ice coatings. 
The effectiveness  of  the  brakes can be reduced 
when the  vehicle  is driven  on a salt-covered 
road and the  brakes are not  used . Here too 
, 
you  should  clean  off accumulated  salt  coating 
from  brake discs  and pads with  a few  careful 
applications  of  the  brake 
Q & . 
Corrosion 
There may be a tendency  for  dirt  to  build  up 
on the  brake pads and corrosion  to  form  on 
the  discs if  the  car is not  driven  regularly  or 
only  for  short  trips  with  little  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 
f irmly  a few  times  from  a moderately  high 
speed

Faults  in the  brake system 
If you should  notice  a  sudden increase in 
brake pedal  travel,  then  one of  the  two  brake 
circuits  may have failed

Low brake fluid  level 
Malfunctions  can occur in the  brake system  if 
the  brake fluid  level is too  low. The brake fluid 
level  is monitored  electronically.

spection 
Q page  258,  Changing  a wheel. 
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 descending  a steep  grade,  reduce 
speed and shift  transmission  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  distance. 
- Under certain  climatic  and operating 
conditions  such as passing through  wa
ter,  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 coat
ings will  be cleaned  off after  a few  care
ful  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  obstruct
ed. Otherwise  the  brake system  could 
overheat  reducing  the  effectiveness  of 
the  entire  brake system. 
- Failure of  one  brake circuit  will  impair 
the  braking  capability  resulting  in an  in
creased stopping  distance.  Avoid driving 
the  vehicle  and  have it  towed  to  the  near
est Audi  dealer  or  qualified  workshop. 
- Never let  the  vehicle  roll  to  a stop  with 
the  engine  shut  off. 
- If  the  brake booster  is not  working,  for 
example  when  towing  your  vehicle,  or 
because  the brake booster  has somehow 
been  damaged,  the  brake pedal  must  be

198  Driving  and  en vironm ent 
Driving  through  water 
on  roads 
Note the  following  to  avoid vehicle damage 
when  driving through  water,  for  example  on 
flooded  roads: 
- The water  must  not  be any higher  than  the 
bottom  of the  vehicle body. 
- Do not  drive faster  than  wa lking speed. 
A 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  re
sto re 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  dr iv
i ng through  it. 
- Do not  stop  the  vehicle,  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 dr iving through  salt  water  because 
i t  can cause  corrosion. 
Operate  your  vehicle 
economically  and 
minimize  pollution 
General 
Your personal  style  of  driving  will  determine 
the  economy  of your  vehicle,  as well  as ex
haust  and  noise levels. 
Fuel  economy, environmenta l impact,  and 
wear  on your engine,  brakes  and tires  largely 
depend  on three  factors: 
- your personal  driving style 
- operating  conditions 
- technical  limitations 
If you anticipate  what  you need  to  do next  and 
drive economically, you can easily cut your 
fuel  consumpt ion by  10-15  percent . This sec
t ion will give you some  tips  on how you  can 
help the  env ironment  and your pocketbook. 
@ 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,  which will vary depending  upon vehi
cle load and  speed,  road and  weather  con 
ditions,  trip  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
ce lerating.  If you anticipate  what  is going to 
happen  next, you will need  to  brake  less  and, 
thus,  acce lerate  less . Let the  vehicle coast 
whenever  possible  - for  example  when  you see 
that  the  next traffic  light  is red.  
Page 201 of 298

Avoid  full  throttle 
Driving at  moderate  speeds  saves  fuel  and 
improves  your  mileage. 
"" Try and  keep well below your car's  maxi-
mum  speed. 
Accelerating  gently  reduces  fuel  consump tion,  engine  wear, and  does  not  disturb  the 
environment. 
F ue l 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
d itions  permit . 
Reducing  unnecessary  idling 
Even when your  car is just  idling it  burns  up 
fuel. 
"" Shut  the  engine off when you are  not  driv
ing the  vehicle. 
""  Do not  warm  up the  veh icle 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 fo r 
just 
30-40 seconds  saves  more  fue l than  is 
bu rned  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  while the  engine  is 
still warming  up . 
(D Note 
Do not  leave engine  idling unattended  af
ter  starting . If warning  lights  should  come 
on to  indicate  improper  operation,  they 
wou ld go  unheeded.  Extended  idling also 
produces  heat,  which cou ld  result  in over-
Dri vin g and  en vironm ent  199 
' 
heating  o r othe r damage  to  the  veh icle or 
other  p roperty . 
Regular  maintenance 
A badly  tuned  engine  unnecessarily  wastes  a 
lot  of fuel. 
""  Have your veh icle serviced at  reg ular i nter-
vals. 
By having your veh icle regu la rly serviced by an 
Audi dealer  he lps to  ensu re  that  it  runs  prop
erly and  economically.  The condition  of your 
vehicle not  only affects  its sa fety and  ability to 
hold  its value,  it a lso affects 
fuel  con sump
tion . 
Check  your oil e ach t ime  you fill  your tank . 
The amount  of o il used  is re lated  to  eng ine 
load and  speed . 
It  is normal  for the  oil consumption  of a new 
engine  to  reach  its lowest  value  after  a certa in 
mileage  has been  driven . 
You must  drive your veh icle about  3,000  m iles 
(5,000 kilometers)  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 
& Ma in
tenance  booklet . Lack of proper  mainte
nance  as well as  improper  use of the  ve
hicle will impair the  function  of the 
em iss io n  cont ro l system  and  cou ld lead 
to  damage. 
- Do not alter  or  remove any component  of 
the  Emission Control Sys tem  unless  ap
proved by the  manufacture r. 
- Do not alter  or  remove any device, such 
as  heat  shie lds, swit ches,  ign it ion w ires, 
valves, which are  designed  to  p rotec t 
your vehicle's  Emission Control System 
and  other  important  vehicle compo
nents .

Engine cooling  system 
Towing  a trailer  makes  the  engine  work  hard
er . It  is  impo rtant  that  the  cooling  system's 
perfo rmance  is  up  to  the  additional  load . 
Make  sure  that  the  coo ling  syst em  has  enough 
f lui d. 
Tire  pressure 
When  towing  a trailer ,  inflate  the  tires  of your

202  Trailer towing 
"Full load"  on the  label  located  on the  driver's 
side  B-pillar  (visible  when the  door  is open). 
Inflate  trailer  tires  to  trai ler and t ire manufac 
turers'  specif ications. 
Lights 
Check to  make sure both  vehicle  and trailer 
lights  are working  properly. 
Safety  chains 
Be sure  trailer  safety chains are properly  con
nected from  the  trailer  to  the  hitch  on the  ve
hicle.  Leave  enough slack in the  chains to  per
mit  turning  corners. When  you  install  safety 
chains,  make sure they  wi ll not  drag  on the 
road when you  are driving. 
The chains should  cross under  the  trailer 
tongue  to prevent  it  from  dropping  in case  of 
separation  from  the  hitch. 
Driving  instructions 
Driving  with a trailer  always  requires  extra 
care  and consideration. 
To obtain  the  best possible  handling  of  vehicle 
and trailer,  please  note  the  following: 
..  Do  not  tow  a loaded  trailer when your  car it
self  is not  loaded. 
.,.  Be  especia lly  careful  when passing other 
ve
hicles. 
..  Observe  speed limits . 
..  Do  not  drive  at  the  maximum  permissible 
speed. 
..  Always apply  brakes early . 
..  Monitor  the  temperature  gauge. 
Weight  distribution 
Towing  a  loaded trai ler with  an empty  car re
sults  in  a high ly unstable  distribution  of 
weight . If  this  cannot  be avoided,  drive  at 
very 
low  speeds  only to  avoid the  risk  of  losing 
steering  control. 
A "balanced"  rig  is easier to  operate  and con
trol.  This  means that  the  tow  vehicle  should 
be loaded  to  the  extent  poss ible and  permissi
ble, while  keeping the  trailer  as  light as possi
ble under  the  circumstances . Whenever  possi- ble, 
transfer  some  cargo to  the  luggage  com
partment  of  the  tow  vehicle  while  observing 
tong ue  load  requirements  and vehicle  loading 
considerations. 
Speed 
T he higher  the speed,  the more  difficult  it  be
comes  for  the  driver  to control  the  rig.  Do not 
drive  at  the  maximum permissible  speed . Re
duce your  speed 
even more  if  load, weather  or 
wind  conditions  are  unfavorable -particularly 
when  going  downhill. 
Reduce  vehicle speed 
immediately if the  trail
er shows the  slightest  sign  of  swaying. 
Do not 
try to  stop  the  swaying by accelerating. 
Observe  speed limits . In some areas, speeds 
for  vehicles towing  trai lers are  lower  than  for 
regular  vehicles . 
Always apply  brakes early. When  driving 
downhi ll, shift  into  a  lower gear to use  the en
gine  braking  effect  to  s low the  vehicle.  Use of 
the  brakes alone can cause them  to  overheat 
and  fail. 
Coolant  temperature 
The  coolant  temperature  gauge¢ page  11 
must be observed  carefu lly. The coolant  tem
perature  can increase  if you  drive  on  long in
clines  in a low  gear  at  high engine  speeds.  Re
duce your  speed  immediately  if  the  LEDs in 
the  top  part  of  the  d isplay turn  on  . 
For  more  information  about  indicator  lights, 
refer  to. ¢ 
page  16 . 
A WARNING 
Anyone  not  properly  restrained in a mov
ing vehicle  is at  a much greater  risk in an 
accident.  Never  let  anyone ride in your  car 
who  is  not  properly  wearing  the  restraints 
provided  by Audi.
