brake pads should  be checked by your  a uthor 
ized Audi  dealer  more  often  than  specified  in 
the 
War ranty & M aint enance booklet . Failure 
to  have your  brake pads inspected  can res ult 
in  reduced brake performance. 
On steep  slopes, you shou ld use the  braking 
effect  of  the  engine . This way, you  prevent  un
necessary wear  on the  brake system.  If  you 
must  use your  brakes, do not  hold  the  brakes 
down  continuously . Pump the  brakes at  inter 
vals. 
Operating  no ise 
Noises may occur when  braking  depending  on 
the  speed, braking  force  and outside  condi
tions  such as temperature  and  humidity. 
Effect  of  w ater  and  ro ad  salt 
In certain  sit uations,  for  example  after  driving 
through  water,  in  heavy rain,  after  overnight 
condensation  or  after  washing  your  car, the  brak ing effect  can be reduced by moisture  or 
ice on the  brake rotors  and  brake pads. The 
brakes must be dried first with a few careful 
brake app lications. 
At  h igher  speeds and with  the  w indshield  w ip
ers turned  on, the  brake pads press against 
the  brake rotors  for  a short  amount  of  time. 
This occurs at  regula r intervals  without  the 
d river  noticing  and provides for  better  brake 
response time  under  wet  condit ions. 
The effectiveness  of  the  brakes can be reduced 
when  the  vehicle  is dr iven on a salt-covered 
road and the  brakes a re not  used . L ikew ise, 
you  clean off  a ccumulated  sa lt  coating  from 
brake discs and  pads with  a few  ca utious ap
p lications  of  the  brake 
c:> .&. . 
Cor rosion 
There may be a tendency  for  dirt  to  bu ild  up 
on the  brake pads a nd corrosion  to  form  on 
the  discs  if  the  car is not  dr iven  regular ly or 
only  for  short  t rips with  little  use of  the 
b rakes. 
I f  the  b rakes are not  used frequently,  or  if  cor
r osion  has formed  on the  discs, it  is advisab le 
t o clean off  the  pads and discs by brak ing 
Int ellig ent  technolog y 189 
firmly  a few  times  from  a moderately  h igh 
speed

Faults  in the  brake  s yst em 
If you shou ld notice  a sudden in crease  in 
brake pedal trave l, then  one of  the  two  brake 
c ircuits  may have fai led 
c:> .&. . 
Lo w  brake fluid  l ev el 
Malfunctions  can occur  in the  brake system  if 
the  brake fluid  level  is too  low . The brake flu id 
level  is monitored  elect ro nica lly. 
Brake booster 
The brake booster  increases the  pressure that 
you generate  with  the  brake peda l. It  works 
only  when  the  engine  is running 
.c:> .& 
Brake lining  wear statu s 
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
sa ry, the  wheel  may be removed  for  th is in 
spect ion 
c:> page 259, Changing a wheel. 
A WARNING 
- New brake pads don' t have the  best  stop
ping  power  and  m ust  be "bro ken-in"  dur
ing the  initial 
100 to 150 miles (150 to 
200 kilometers)  of  normal  c ity  driving. 
You can compensate  for  this  by pressing  the  brake pedal  more  firmly.  Th is also 
applies  later  when  new pads are instal
led. 
- You should  perform  braking  maneuvers  for  the  purpose  of  cleaning  the  brake 
system  only  if  road conditions  permit. 
Other  road use rs must  not  be put  at  risk -
you  may ca use an accident! 
- Before descend ing a steep  grade,  reduce 
speed and sh ift  transmission  into  a lower 
gea r or l ower  dr iving  range . Do not  ride 
the  brakes or  hold  t he pedal down  too 
long  or too  often . Th is could  cause  the 
brakes to  get  hot  and diminish  braking 
efficiency . 
- Do not  " ride the  brakes"  by  res ting you r 
foo t on the  pedal when you do  not  intend  .,..

to  brake. This may cause  the  brakes to 
overheat,  premature  wear  and  increased 
stopp ing distance. 
- Under certain  climatic  and  operating 
condit ions  such as  passing  through  wa
ter,  driving in heavy ra in or after  wash ing 
the  vehicle, the  effect iveness  of the 
brakes  can be  reduced . In winter,  ice can 
accumulate  on the  brake  pads,  linings, 
discs and  drums.  Carefully apply  brakes 
f or a test . B rakes will dry a nd  ice coat
ings will be cleaned  off after  a few  ca re 
ful  brake applications. 
- Driv ing for an  extended  pe riod of time  on 
salt -covered  roads without  using you r 
brakes  can also  affect  braking  efficiency. 
Clean off accumulated  salt  coating  from 
brake discs  and  pads  w ith  a few careful 
brake applicat ions. 
- 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 . O therwise  the  brake system  could 
overheat  reducing  the  effectiveness  of 
the  ent ire brake system. 
- Failure of one  brake c ircuit will impair 
the  braking  capability  resulting  in an  in creased  stopp ing distance.  Avoid driv ing 
the  vehicle and  have it towed  to  t he near
est  author ized Audi dealer  or qualif ied 
workshop. 
- Never let  the  vehicle roll to  a stop  w ith 
the  engine  shut  off. 
- If the  brake  booster  is not  working,  for 
example  when  towing your ve hicle, or 
because  the  b rake booste r has  somehow 
been  damaged,  the  brake  pedal  must  be 
pressed  considerab ly harder  to  make  up 
for  the  lack of booster  assistance.

Driving  with  your 
quattro ® 
Applies  to vehicles:  with  a ll-wheel  drive 
With  all-wheel  drive,  all  four  wheels  are driv
en. 
Gener al inform ati on 
W ith  all-wheel  drive,  power  is distributed  to 
all  four  wheels . This  happens  automatically 
depending  on  your  dr iving  style  and  the  road 
conditions  at  the  t ime.  See  also 
c:> page  185. 
A center  different ial  distr ibutes  the  dr iv ing 
power  var iably  to  the  front  and  rear  axle . It 
works  together  with  selective  wheel  torque 
control,  which  activates  when  driving  throug h 
curves

tial*,  power  dist ribution  to  the  rear  wheels  is 
variable  and  can  be  adjusted  with  drive  select 
c:> page  113. 
The  all-wheel  drive  concept  is designed  for 
h igh  engine  power.  Yo ur vehicle  is exception 
ally  powerful  and  has  exce llent  driving  charac 
teristics  both  under  normal  driving  conditions 
and  on  snow  and  ice.  Always  read  and  fo llow 
safety  precautions 
c:> A . 
Winter  t ir e s 
When  driv ing  in the  w inter,  your  veh icle w ith 
all-wheel  drive  has  an  advantage, 
even with 
regular  tires.  In  winter  road  conditions  it  may 
be  advisable  to  mount  winter  tires  (or all-sea
son  t ires)  for  improved  driveability  and  brak
ing:  these  tires  must  be  mounted  on 
a ll four 
w heels . See  also c:> page  250,  Winter  tires . 
Intellig ent  technolog y 191 
Tire chain s 
Where  tire  chains  are  mandatory  on  certain  roads,  this  no rma lly also  applies  to  veh icles 
with  all-wheel  drive 
c:> page  251,  Snow 
chains. 
Replacing wheels /tires 
Vehicles  with  a ll-wheel  drive  must  always 
have  tires  of  t he same  s ize.  A lso  avoid  tires 
with  different  tread  depths .  For  detai ls  see 
page 
c:> page  246,  New  tires  and  replacing 
tires  and  wheels . 
Off-Road  driving? 
You r A udi  does  no t have  enough  ground  clear 
ance  to  be  used  as  an  off-road  vehicle . 
It is 
therefore  best  to  avoid  rough  tracks  and  un 
even  terrain  as  much  as  possib le . Also  refer  to 
c:> page  194. 
A WARNING 
Always  adjust  your  dr iving  to  road  and  traf
f ic conditions.  Do not  let  the  extra  safety 
afforded by all-wheel drive tempt you into 
taking  extra  risks . 
- Although  the  all-wheel  drive  is very  ef
fective,  always  remember  that  braking 
capacity  is  lim ited  by tire  traction.  You 
should  therefore  not  d rive at  excessive 
speeds  on  icy or  slippe ry road  surfa ces. 
- On wet  road  surfaces,  be  careful  not  to 
drive  too  fast  because  the  front  wheels 
co uld  begin  to  slide  on  top  of  the  water 
(aquaplaning) . If this should  occur,  yo u 
will  have  no  warning  from  a s udden  in 
crease  in  engine  speed  as  w ith  a front
wheel  drive  veh icle.  Always  drive  at 
speeds  which  are  su ited  to  the  road  con
ditions  -risk  of  crash.

Energy  management 
Starting  ability  is optimized 
Energy management  controls  the  distribution 
of  electrical  energy  and  thus  optimizes  the 
availability  of  electrical  energy  for starting 
the  engine. 
If  a vehicle with  a conventional  energy  system 
is not  driven  for  a long  period  of time,  the  bat
tery  is d ischarged  by  idling  current  consumers 
(e.g.  immobilizer).  In ce rtain  circumstances  it 
can  result  i n there  bei ng  insuff ic ient  ene rgy 
avai lab le to  start  the  engine . 
Intell igent  energy  management  in your vehi
cle  hand les  the d ist ribu tion of  elect rical ener
gy. Starting  ab ility  is mar ked ly imp roved  and 
the  life of the  battery  is  extended . 
Basically , energy  management  consists  of 
batt ery  diagno sis , idling  curr ent  manag e
ment 
a nd dynami c energy  man agement . 
Battery  diagnosis 
Battery  d iagnosis  continuously  determ ines 
the  state  of the  battery . Sensors  determ ine 
battery  vo ltage,  battery  current  and  battery 
temperature . This dete rm ines  the  current 
sta te of  charge  and  the  power  of  the  ba ttery. 
Idling  current  management 
Idling  current  management  reduces  energy 
consumption  wh ile the  vehicle  is stand ing . 
W ith  the  ignition  switched  off,  it  cont ro ls the 
ene rgy s upply to  the  va rio us e lectrica l compo
nents . Data  from  battery  diagnosis  is consid
e red. 
Depending  on the  battery's  state  of  charge, 
i nd ividua l consumers  are  grad ually t urned  off 
to  p revent  ex cess ive d isc harge  of the  ba ttery 
and  thus  mainta in start ing capability. 
Dynamic energy management 
While  the  vehicle  is be ing  dr iven , dynamic  en
e rgy management  dist ributes  t he energy  gen
e rated  accordi ng to  the  needs  of the  individu
a l componen ts. 
It reg ulates  consump tion, so 
that  more  electrical  ene rgy is not  being  used  than 
is being  generated  and  ensures  an  opti 
mal  state  of charge  for  the  battery. 
(D Tips 
- But  even  energy  man ageme nt  canno t 
negate  the  limi ts of  physics . Conside r 
that  the  powe r and  life  of  a battery  are 
limited . 
- If start ing ability  is threatened,  the  indi 
cator  light (•) appears ~ 
page  17. 
What  you should  know 
The highest  priority is given  to  maintaining 
starting  capability . 
The b attery  is  severe ly  taxed  in short -d istance 
driv ing,  in ci ty traff ic and  during  t he cold  time 
of yea r. Ab undant  electrical  energy  is re
quired,  but  on ly a little  is generated . It  is also 
critical  if the  engine  is not  r unning  and  electri
ca l components  are  turned  on . In  this  in
stance  ene rgy  is  be ing consumed  but  none  is 
being  generated . 
It  is  in precisely  these  s ituations  that  you will 
notice  energy  management  active ly reg ulat
ing the  d istribution  of  energy. 
Vehicle  stand s for  an e xtended  period 
If you do  not  drive your vehicle  over a period 
of several  days  or weeks,  e lectrica l compo 
nents  are  gradually  cut  back or  sw itched  off. 
This reduces  energy  consumption  and  ma in
ta ins start ing capability  over a longer  pe riod . 
Some  of  the  convenience  functions  may  not 
operate,  such  as  the  interior  lights  or  the 
power  seat  adjustme nt.  The convenience 
f unc tions wi ll be  available  again  when  yo u 
swi tch on  the  igni tion and  sta rt the  eng ine . 
With  the  engine turned  off 
If you  listen  to  the  radio,  for  examp le, w it h 
the  engine  t urned  off or  use  other  MMI func
t ions,  t he battery  is  be ing discharged. 
If starting  capability  is  jeopardized  due  to  en 
ergy consump tion, the  following  warning  ap-
pears  in  the  MM I display:  .,,.  
Page 195 of 302

Please start the  engine  soon or the  system 
will  be turned  off. 
The warning  ind icates  that  the  system  will be 
turned  off  automa tically  after 3 minutes.  If 
you wish  to  continue  using  the  functions,  you 
have to  start  the  engine . 
With  the  engine  running 
Although  electrical  energy  is generated  when 
the  vehicle  is be ing driven , the  battery  can  be
come  discharged.  This happens  most ly when 
litt le energy  is being  generated  and  a great 
deal  consumed  and  the  battery's  state  of 
charge  is not  optimal. 
To br ing t he ene rgy  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  requ ire a great  deal  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  ba lance  has  bee n restored. 
You will also  notice  that engine  idle speed  has 
been  increased  slightly . This is normal  and  not 
a cause  for  concern.  By increasing  engine  idle 
speed  the  add itional ene rgy  required  is gener
ated  and  the  ba ttery  is  charged.

The  first  1,000 miles 
(1,500  km)  and 
afterwards 
New engine 
The engine  needs  to be  run-in during  the  first 
1,000  miles  (1,500  km). 
For the fir st  600  miles (1,000 
kilometers ): 
.,.  Do not  use full  throttle. 
...  Do not  drive  at  engine  speeds that  are more 
than  2/3  of  the  max imum  permitted  RPM. 
From 600  to  1,000  miles (1 ,000  to 
1,500  kilometers): 
.,.  Speeds can gradually be increased to  the 
max imum  pe rm iss ible  road or  eng ine speed . 
During and after  break-in  per iod 
...  Do not  rev the  eng ine up to  h igh speeds 
when  it  is cold.  Th is  app lies whether  the 
transmission  is in N (Neutral)  or  in gear. 
After  the  break- in period 
...  Do not  exceed max imum  eng ine speed  un
der any circumstances  . 
...  Upshift  into  the  next  higher  gear 
before 
reaching  the red area at  the end of  the  tach
ometer  scale¢ 
page  10. 
During  the  first  few  hours  of  driving,  the  en
g ine's  inter na l friction  is higher  tha n later 
when  alt the  moving  parts  have been broken 
i n.  How welt  this  break- in process is done  de
pends to  a conside rable  extent  on  the way the 
ve hicl e is driven  du ring the  first  1,000  miles 
(1, 500  kilome ters). 
(D Note 
E xtremely  high engi ne speeds are auto
mat ica lly  re duced.  However, these  rpm 
lim its  are programmed  for  a n engine  welt 
r u n- in,  not  a new eng ine. 
{® For the  sake of the  environment 
Do not  drive  with  unnecessarily  high  en
g ine speeds - upshifting  ear ly saves fuel, 
reduces no ise and  protects  the  environ
ment. 
,  New tires 
If  your  vehicle  is runni ng on new tires,  drive 
very carefully  for  the  first  350  miles  (500  kilo meters)  after  fitting. 
_& WARNING 
N ew  tires  tend  to be  slip pery a nd mus t  al
so be  "broken -in" . Be s ure to  remembe r 
this  dur ing the  fi rst  350  mi les (500  kilo 
meters) . Brake gently . Avoid fo llow ing 
closely  behind  other  vehicles or  other  sit
uations  that  m ight  require  sudden,  hard 
braking. 
Avoid  damaging  the 
vehicle 
When  you a re d rivi ng on poo r roads, or  over 
cu rbs, ste ep ramps,  etc.,  ma ke certai n that 
low- ly ing  parts  s uch as spoile rs and ex ha ust 
s ystem  parts  do not  bot tom  o ut  and get  dam 
aged. 
T his is espec ially  true  for  veh icles with  low
s lu ng chassis (s por ts chassis)* and fully  load
ed vehicles. 
Driving  through  water 
on  roads 
Note  th e following  to  avoid vehicle damage 
whe n driving  through  water,  for  examp le  on 
flooded  roads: 
- The wa ter  must  not  be any hig he r th an the 
bottom  of  the  vehicle  body . 
- Do not  dr ive faste r than  walk ing speed.  
Page 197 of 302

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
store  the  full  brak ing  effect. 
([)  Note 
Vehicle  components  such  as  the  engine, 
transmiss ion,  suspension  or  electrical  sys
tem  can  be  severely  damaged  by driving 
through  wate r. 
@ Tips 
- Check the  depth  of the  water  before  dr iv
i ng  through  it. 
- Do not  stop  the  veh icle,  dr ive  in  reverse 
or  switch  the  engine  off  when  driving 
th rough  water. 
- Keep  in  mind  that  oncoming  vehicles 
may  create  waves  that  raise  the  water 
level  and  make  it  too  deep  for  you r vehi
cle  to  drive  th rough  safely. 
- Avoid dr iving  through  sa lt  water  because 
i t  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. 
11-Always  use  lead-free  gasoline q page  214, 
Fuel supply . 
"'" Never  run  the  tank  down  a ll the  way to 
empty. 
11-Never  put  too  much  motor  oil  in your  en-
gine 
q page  224, ~ Adding  engine  oil  . 
11-Never  try  to  push -or tow-start  your  veh icle . 
The catalytic  converter  is an  efficient  "clean up"  device  built  into  the  exhaust  system  of 
the  vehicle . The  catalytic  converter  burns 
many  of the  pollutants  in the  exhaust  gas  be
fore  they  are  released  into  the  atmosphere . 
Drivin g and  en vironm ent  195 
The  exclusive  use  of  unleaded  fuel  is  critically 
important  for  the  life  of the  catalytic  convert
er  and  proper  funct ion ing  of  the  engine. 
A WARNING 
-
- Do not  park  or  operate  the  vehicle  in 
areas  where  the  hot  exhaust  system  may 
come  in  contact  with  dry  grass,  brush, 
fuel  spill  or  other  mate rial wh ich  can 
cause  a fir e. 
- Do not  apply  additional  undercoating  or  rustp roof ing  on  or  near  the  exhaust 
manifold,  exhaust  pipes,  catalytic  con
ve rter  or  heat  shields.  During  driv ing,  the 
substance  used  for  undercoating  co uld 
overheat  and  cause  a fire. 
(D Note 
- Be aware  that  just  one  tank  filling  with 
leaded fu el  w il l  already  ser iously  de
gra de  the  performance  of the  catalytic 
c onverte r. 
- Do not  ex ceed  t he  cor rect  eng ine  oil  level 
qpage 224. 
- Do not  drive  until  the  fue l tank  becomes 
comple tely empty.  The  engine  co uld  m is
fire . Unburned  fuel  could  also  get  in to 
the  exhaust  system  and  th is  co uld  cause 
the  catalytic  converter  to  overheat . 
- Do not  turn  off  the  ignition  while  the  ve 
hicle  is moving. 
- Do not  continue  to  ope rate  your  veh icle 
unde r these  conditions,  as  otherwise  fuel 
can  reach  the  catalytic  converte r.  T his 
cou ld  result  in overheating  of the  con
verter,  requir ing  its  replacement. 
- To assure  efficient  operation  of  the  Emis 
sion  Control  System: 
- H ave you r vehicle  maintained  prope rly

@ For the  sa ke of the  environment 
Even when  the  Emission Contro l System  is 
operating  properly,  the  exhaust  gas can 
have a sulfur-like  exhaust  gas smell  under 
some operating  states.  This depends  on 
the  sulfur  content  of  the  fue l being  used . 
Using a different  brand  of  fuel  may help, 
or filling  the  tank  w ith  lead-free  super

Operate  your  vehicle 
economically  and  minimize  pollution 
General 
Your personal  style  of  driving will determine 
t he  economy  of your  vehicle, as  well as  ex 
haust  and  noise  levels. 
Fue l economy,  environmental  impact , and 
wear  on you r engine,  bra kes and t ires  la rgely 
depend  on th ree factors: 
= yo ur  personal  dr iv ing sty le 
- operating  conditions 
- technical  lim itations 
If  yo u anticipate  what  you  need to  do next  and 
drive  economically,  you  can easi ly cut your 
fue l consumption  by 10-15  percent.  This sec 
tion  will  give you some t ips on how you ca n 
he lp the  environmen t and your  pocketbook. 
(D Tips 
The consumpt ion estimates  as published 
by ENVIRONMENTAL PROTECTION AGENCY 
(EPA) and Transport  Canada may not  co rre
spond to  your  actual  consumption  on the 
road, wh ich will  vary  depending  upon  vehi
cle  load an d speed,  road and weather  con
ditions,  tr ip  le ngth,  etc. 
Drive smoothly  and  keep a  lookout 
ahead 
Vehicles use  the  most  fuel  when  they  are ac
celerating . 
.,. Avoid unnecessa ry accelerating  and  braking.  Vehicles use the  most  fuel  when  they  are ac
ce le rating.  If  you anticipate  what  is going  to 
happen  next,  you will  need to  brake  less and, 
th us, acce lerate  less. Let the  vehicle  coast 
whenever  possible  -for  example  when you  see 
that  the  next  traff ic light  is red . 
· Avoid full  throttle 
Driving at  moderate  speeds  saves  fuel  and 
improves your  mileage. 
..  Try and keep well  below your  car's maxi-
m um speed . 
Acce lerat ing gently  red uces fue l cons ump
tion,  engine  wear, and does not  disturb  the 
environment. 
F uel consumpt ion,  exhaust  emissions  a nd en 
gine  noise inc rease disproportionate ly at  high 
speeds . If  yo u drive  at  approximately  th ree 
quarters  of  top  speed, fuel  consumption  w ill 
be reduced by one  half.  Never drive  faster 
than  the  posted  speed limit  and weathe r con
ditions  pe rm it. 
Reducing unnecessary idling 
Even when your  car is jus t idling it  burns  up 
fuel. 
..  Shut  the  eng ine off  when you  are not  driv 
ing  the vehicle . 
..  Do  not  warm  up the  vehicle  by letti ng the 
eng ine  run at  idle . 
It  makes sense to  shut  off  the  engine  in traffic 
jams,  when wa it ing for  tra ins to  pass at  rail
r oad crossings,  or  at  traffic  lig hts  that  have 
long  wai ts on red . Tu rn ing the  eng ine off  for 
j ust  30-40  seconds saves more fuel  tha n is 
burned  start ing t he e ngine  aga in. 
It  takes a long  t ime for  the  engine to  warm  up 
fully  when  it  is ru nning  at  id le.  However, wea r 
and noxious  emissions  a re espec ia lly high 
whe n the  eng ine  is wa rm ing  up. So you s hou ld 
dr ive  away  as soon  as yo u start  the  engine  and 
avo id  running  at  high  rpms  whi le 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 
would  go unheeded.  Extended  idling  also 
produces  heat,  which  could  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 
author iz ed Audi  dealer  helps to  ensure that  it 
runs  properly  and economically . The condition 
of  your  vehicle  not  only  affects  its  safety  and 
ab il ity  to  hold  its  value,  it  also affects 
fu el 
c onsump tion . 
C hec k your oil  each tim e you  fill your t ank . 
The amount  of  oil  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  d rive yo ur vehicle  about  3 ,000  miles 
(5,000  kilometers)  be fore you can properly 
assess oi l consumption. 
This a lso applies  to  fuel  consumption  and en
g ine output .

-Have your  vehicle  maintained  properly 
and  in accordance wit h the  service  rec
ommendat ions i n your  Warranty 
& Main
tenance  booklet . Lack of  proper  mainte 
nance as well  as improper  use of  the  ve

-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  shie lds, switches,  ignition  wires, 
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 rela tively 
high  on short  trips  . 
.,.  Try to  avoid driving  short  distances  with  a 
cold  engine. 
The engine  and cata lytic  converter  have to 
reach their  opt imal 
op erati ng t emper ature to 
reduce fuel  consumpt ion and  noxious  emis
s ions effectively . 
Just after  starting,  a co ld engine  in a mid-size 
car only  achieves a fuel  economy of  6-8  mi les 
per gallon  (30-40  l/100  km). After  about a 
half  a mile,  fuel economy  climbs  to  12 mpg 
(20  l/100  km) . After  about 
2 .5 miles  (4  km), 
the  e ngine  is at  its  proper  operat ing tempera
ture  and fue l economy  has reached a normal 
level.  So you  can see that  you should  avo id 
short  trips  whenever  poss ible. 
T he 
outs ide t emp erature is also cr itical  in th is 
regard.  Your car consumes  more  fue l in the 
winter  than  in the  summer.

Driver  messages 
App lies to  veh icles : all road 
There is only one  right  way  to drive in difficult 
conditions:  slowly  and  with  caution! 
When  driving  offroad,  observe  the  follow ing : 
..  Never  drive  the  vehicle  in terrain  which  is 
not  suitab le for  the  vehicle,  or  which  ex
ceeds  your  driving  ski lls.  Never  take  any  un
necessary  risks! 
..  Drive  slowly  and  caut iously! 
..  Pay attention  to  the 
ground  clearanc e of 
your  veh icle!  This  may  vary  depending  on 
the  load  and  composition  of  the  ground  and 
t he  environment.  The  d river  is therefore  re
sponsib le for  deciding  whether  a veh icle  can 
handle  a  specific  situation  . 
..  Activate  the 
ESC-Offroad-Mode r::;, page  187 
as  needed . 
Difficult  terrain 
Never  drive  in areas  that  are  not  fam iliar  to 
you  and  d rive slowly  when  offroad  and  be  p re
pared and expect the  unexpected (e .g. pot 
holes,  boulders , tree  stumps,  etc.) 
T o  p reven t the  veh icle  from  bottoming  and 
avo id  damage  to  the  unde rbody,  yo u should 
drive  straight  across  severe  bumps  in the 
ground  with  only  one  side  of  the  ve hicle  so 
that  only  two  of  your  whee ls  cross  the  bumps. 
Drive quickly  th rough  sandy  or  marshy  offroad 
sections  and  do  not  stop,  if at  all  possible.
