Adjusting  the  steering  wheel  column 
The steering  wheel  position  can be  continu
ously adjusted  in height  and  distance . 
Fig. 81 Lever under the  steering  column 
~ Push  the  lever¢ fig.  81 down  ¢ .&_. 
~ Move the  s teer ing  whee l to  the  desired  po
sition. 
~ 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  steer ing  wheel. 
A WARNING 
Improper  use  of steering  wheel  adjust
ment  and  improper  seating  position  can 
cause  serious  personal  injury. 
- Adjust  the  steer ing  whee l co lumn  only 
when  the  vehicle  is  not  moving  to  pre
vent  loss  of veh icle  control. 
-
- Adjust  the  dr iver's  seat  or steering  wheel 
so that  there  is  a  minimum  of  10  inches 
(25  cm)  between  your  chest  and  the 
steering  wheel ¢ 
page 92, fig.  104. If 
you  cannot  maintain  this minimum  dis
tance,  the  airbag  system  cannot  protect 
you  properly . 
- 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 
equipment  is 
available. 
- If  the  steer ing  whee l is aligned  with  your 
face,  the  supplemental  dr iver's  a irbag 
cannot  provide  as  much  protection  in an 
accident . Always  make  sure  that  the 
steer ing  whee l is al igned  with  your 
chest. 
- Always hold  the  steering  wheel  w ith  your 
hands  at  the  9  o'clock  and  3  o'clock  posi
tions  to  reduce  the  risk of  personal  injury  if the  dr iver's  airbag  dep loys.

o'clock  position  or  with  you r hands  inside 
the  steering  wheel  rim  or  on  the  steering 
wheel  hub . Ho lding  the  steering  wheel 
the  wrong  way can  cause  serious  injuries 
to  the  hands,  arms  and  head  if the  driv
er's  airbag  deploys.

If  the  vehicle  battery  has been disconnect
ed and then  reconnected,  then  you m ust 
leave the  key in  pos ition  @for  abo ut  5 
seconds before you  can start  the  engine.

- The brake booster  and servotronic  on ly 
work  when  the  engine  is running.  With 
the  ignition  turned  off,  you  have to  apply 
more  force  when  stee ring  or  braking. 
S ince you  cannot  steer  and stop  no rma l

Cruise  control 
Introduction 
The cruise control  system  keeps  the  speed 
constant. 
The cruise  control  system  makes  it  possible  to 
drive  at  a  constant  speed  over 20  mph  (US 
model)  or  30  km/h  (Canadian  model) . This  is 
true  only  to  the extent  that  engine  power  or 
engine  braking  effect  allow . Using  the  system 
takes  the strain  off  the "gas  pedal  foot"  - es
pecially  on  long  trips. 
In  the  control  mode,  the  indicator  light  in the 
instrument  cluster is  lit 
aijj(1)~1~ (US model);II 
(Canadian  model). 
The  cruise  control  system  automatically 
switches itself off  immediately under  the fol
lowing  conditions: 
- Pressing  the brake  pedal. 
- Pressing  the  clutch  pedal. 
A WARNING 
-Always  pay attention  to traffic  even  when 
the  cruise  control  system  is switched  on. 
You are  always  responsible  for  your  speed  and  the  distance  between  your  ve
hicle  and  other  vehicles. 
- For safety  reasons,  the  cruise  control  sys
tem  should  not be  used  in the  city, in 
stop-and-go  traffic, on  twisting  roads 
and  when  road  conditions  are  poor  (such 
as  ice,  fog,  gravel,  heavy  rain  and  hydro
planing)  -risk  of  accident. 
- Turn  off  the  cruise  control  system  tem
porarily  when  entering  turn  lanes, high
way  exit  lanes  or  in construction  zones. 
- Please  note  that  inadvertently  "resting" 
your  foot  on  the  accelerator  pedal  causes 
the  cruise  control  system  not  to  brake. 
This  is because  the  cruise  control  system 
is overridden  by the  driver's  acceleration. 
(D Note 
On  manual  transmission  vehicles: If you 
shift  into  neutral  with  the  cruise  control  system  switched  on,  always  depress  the 
clutch 
pedal! Otherwise  the  engine  will 
race  and  could  be  damaged  as  a  result. 
(D Tips 
When  driving  on  steep  downward  grades, 
the  cruise  control  system  cannot  keep  the 
speed  constant.  The  vehicle's  own  weight  increases  the  speed.  Shift  into  a  lower  gear 
in  plenty  of time  or  brake  the  vehicle  with 
the  foot  brake. 
Saving  the  speed 
The desired  speed must  be  saved.

You can  also increase your  speed  by pressing 
the  accelerator  pedal. After  you  release the 
accelerator  peda l,  the  system  automat ically 
adjusts  back  down to  the  speed  you  previously 
set . 
However,  if you  exceed  this  speed  by 5  mph 
(10  km/h)  for longer  than  5  m inutes,  the  stor
ed  speed  will  be  deleted.  You will  have to re
