Normal  temperature 
The  engine  has  reached its  operating  tempera
ture  once  the  LEDs up  to the  center  of  the  gauge 
turn  on  under  norma l driving  conditions . The 
LEDs  higher  up  may  turn  on  when  the  engine  is 
under  heavy  load  or  the  exterior  temperature  is 
high.  This  is  no  need  to  worry  as  long  as  the. 
warn ing  light  in the  instrument  cluster  does  not 
illuminate . If  the  LEDs in  the upper  area  of  the 
d isplay  and  the  ind icator  light . in the  instru
ment  cluster  display  tu rn  on , the  coolant  temper
ature  is too  high

_& WARNING 
-Always  observe  the warning  in  ¢ page  220, 
Working  in the  engine  compartment, 
before 
opening  the  hood  and  checking  the  engine 
coolant  level. 
- Never  open  the  engine  hood  if you  see  or 
hear  steam,  or  if you  see  engine  coolant 
dr ipping  from  the  engine  compartment.  You 
could  burn  yourself.  Let the  engine  cool  off 
first  so  that  you  cannot  hear or  see  any 
steam or engine coolant. 
(D Note 
-Mounting  additional  lights or  accessories  in 
front  of  the  air  inlets  reduces the  cooling  ef
fect  of  the  radiator.  At  h igh  outside  temper
atures  or  high engine  load,  the  engine  could 
overheat . 
- The  front  spoiler  has  been  designed  to  prop
erly  distribute  the  cooling  air  when  the  veh i
cle  is  moving. 
If the  spo iler  is  damaged,  this 
could  reduce the  cooling  effect and  the  en
gine  could  then  overheat.  Ask your author
iz ed  Audi  dealer  for  assistance. 
Tachometer  (engine  rev counter) 
The tachometer  indicates  the  engine  RPM (revo
lutions  per  minutes). 
If engine  RPM drops  below 1,500,  you  should 
downshift  to  the next  lower  gear.  The red  area  at 
the  end  of  the  scale  indicates  maximum  permis
sib le  eng ine  RPM  after  the  break-in  period. Be
fore  reaching  this  area,  move  the  selector  lever 
Instruments  and indicator  lights 
to  position  "D (Drive)"  or  ease  your  foot off  the 
acce lerator  pedal. 
(D Note 
The tachome ter  needle  should  only briefly  be 
in  the  red  zone: you could  damage  your  en
gine!  The  beginning  of  the  red zone  varies  de
pending  on  the  engine . 
@ For the  sake of  the  environment 
Upshifting early saves  fuel and  reduces  en
gine  noise. 
Fuel gauge 
The  fue l gauge  only  works  when  the  ignition  is 
on.  If  the  fuel  level  drops  below  4  gallons  (15  lit
ers),  the  bottom  LED turns  red and  the  indicator 
l ight tllturns  on 
¢page  21. The  bottom  LED 
blinks  red  when  the  fue l level  is very  low . 
The  possible  range based  on  the  current  fue l lev
el  is shown  in  tab@¢ 
page  23,  fig.  4. 
(D Note 
Never  run the tank  completely  dry.  An irregu
l ar  supply  of  fuel  can  cause  engine misfiring 
and  fuel  could  enter  the exhaust  system.  The 
catalytic  converter  could  then overheat  and 
be  damaged.

brake  system  inspected. 
- Always  keep  in  mind  that  after  several  brake 
applications,  you  will  need  greater  pressure 
on  the  brake  pedal  to  stop  your  vehicle.  Do 
not  rely  on  strained  brakes  to  respond with 
maximum  stopping  power  in  critical  situa
tions.  You  must  allow  for  increased  braking 
distances . The  extra  distance  used  up  by 
fading  brakes  could  lead  to an  accident. 
PARK/( ®) Electromechanical  parking  brake 
The warning/indicator  light  monitors  the  elec

set . 
- (USA models)  ,. (Canada models)  Cau
tion:  Vehicle  parked  too  steep 
If  the  indicator  light  blinks  and  the  message  ap
pears,  there  is  not  enough  braking  power  to  keep 
the  vehicle  from  rolling.  The  brakes  have  over heated.  The  vehicle  could  roll  away  even  on  a 
small  incline . 
Press brake  pedal to  release parking  brake 
To release  the  parking  brake, press  the  brake 
pedal  and  press  the  button~ or  start  driving

burns.  Wait  until  you  no  longer see  or hear 
steam  or  coolant  escaping. 
- The  engine  compartment  in  any  vehicle  can 
be  a  dangerous  area.  Stop  the  engine  and

fu lly on  the  side  of  the  road.  See  your  autho riz ed 
Aud i deale r or  qualified  repair  facility. 
A WARNING 
-
If  the  eng ine  stops  while  dr iving,  a  la rge 
amount  of  braking  force  is req uired . This  in
creases  the  risk  of  an  accident.  As long  as  the 
vehicle  rolls  with  the  ignition  switched  on  and  there  is enough  battery  charge,  the  powe r 
steering  will  still  work . If  not,  a  la rge  amount

as  soon  as  possible. 
- USA models: If  the 1111 warning  light,  the 
DJ warning  light  and  the  9warning  light 
come  on  together,  the  rear  wheels  could 
lock  up first  under  hard  braking.  Rear  wheel 
lock-up  can  cause  loss  of  vehicle  control  and 
an  accident.  Have your  vehicle  repaired  im
