Effect of  wat er and  road  salt 
In  ce rtain  situations,  for  example  after  driving 
through  water,  in  heavy  rain,  afte r ove rnight  con 
densation  or  after  washing  your  car,  the  braking 
effect  can  be  reduced  by moisture  or  ice on  the 
brake  rotors  and  brake  pads.  The  brakes  must  be 
dried  first  w ith  a few  careful  brake  applications. 
At higher  speeds  and  with  the  windshie ld  wipers 
turned  on,  the  brake  pads  press  against  the  brake  rotors  for  a  short  amount  of  time.  Th is  occurs  at 
regular  intervals  without  the  driver  noticing  and 
provides  for  better  brake  response  time  under 
wet  conditions . 
The  effectiveness  of  the  brakes  can  be  reduced 
when  the  vehicle  is driven  on  a  salt-covered  road 
and  the  brakes  are  not  used.  Likewise,  you  clean 
off  accumulated  salt  coat ing  from  brake  discs 
and  pads  with  a few  cautious  applications  of  the  b rake ¢_&. . 
Due to  their  surface  character istics,  ceramic 
brake  roto rs* absorb  mo isture  in such  condit ions. 
This can  cause  a temporary  reduc tion  in  braking 
force  compared  to  dry  brakes.  You can  compe n
sate  fo r th is  by press ing  the  b rake  peda l harder. 
Corrosion 
There  may  be  a  tende ncy for  d irt  to  bu ild  up  on 
the  brake  pads  and  corros ion  to  form  on  the  discs 
if the  car  is  not  dr iven  regularly  or  only  fo r sho rt 
tr ips  with  little  use  of  the  brakes. 
If  the  brakes  are  not  used  frequently,  or  if corro
sion  has  formed  on  the  discs,  it  is  adv isable  to 
clean  off  the  pads  and  discs  by brak ing  firmly  a 
few  t imes  from  a  mode rately  h igh  speed ¢,& . 
Faults  in the  brake  system 
If  you  should  notice  a sudden increase  in  brake 
pedal  travel,  then  one  of  the  two  brake  c ircuits 
may  have  failed 
¢ ,& . 
Low  brake  fluid  le vel 
Malfunct ions  can  occur  in the  brake  system  if the 
brake  fl uid  level  is too  low.  The  brake  fluid  level 
is monitored  electronically .

Brake  lining  wear  status 
Brake  lining  wea r may  be  chec ked  by visua l in
spe ct ion  of  the  condition  of  the  brake  pads 
t hr ough  the  openings  in t he wheel.  If  necessary, 
the  wheel  may  be  removed  for  this  inspection

_8 WARNING "'----
-New  b rake  pads  don't  have  the  best  stop
p ing  power  and  must  be  "broken-in"  d uring 
the  initial  250  miles  (400  km).  The  b reak-in 
period  can  be  considerably  longer  for 
veh icles  with  ceramic  brake  roto rs*. You can 
compensate  for  this  by pressing  the  brake 
pedal  mo re firmly.  This  also  applies  late r 
when  new  p ads  are inst alled. 
- You shou ld  pe rform  braking  maneuvers  for 
the  purpose  of  cleaning  the  brake  system 
only  i f  road  condit io ns  pe rmit.  O ther  ro ad 
users  m ust  no t be  put  at  r is k - you  may 
cause  an  accident! 
- Before  descending  a steep  g rade,  reduce 
speed  and  shift  transmission  into  a  lower 
gear  o r lower  driving  range.  Do not  r ide  the 
brakes  or  hold  the  pedal  down  too  long  or 
too  often.  This  cou ld  cause  t he  b rakes  to  get 
hot  and  dimin ish  braking  effic iency. 
- Do not  " ride  the  brakes"  by rest ing your  foot 
on  the  pedal  when  you  do  not  intend  to  brake.  This  may  cause  the  brakes  to  over
heat,  premature  wear  and  increased  stop
p ing  distance . 
- Unde r certain  climatic  and  ope rating  condi
tions  such  as  passing  t hrough  water,  d riving 
i n  heavy  rain  o r afte r wash ing  the  veh icle, 
the  effectiveness  of  the  brakes  ca n be  re
duce d. In  winter,  ice can  accum ulate  on  the 
b rake  pads,  lin ings,  discs  and  dr ums.  Care
fu lly apply  brakes  for  a test.  Brakes  will  d ry 
an d ice coatings  will  be  cleaned  off  after  a 
few  ca refu l brake  applications.
