Child  Safety 
Booster  seats  and  safety  belts 
Properly used  booster  seats  can help  protect  children 
weighing  between  about 40 lbs.  and  80 lbs.  (18  kg  and 
36  kg)  who  are less  than  4 ft. 
9 in. 
(57  inches/1.45  meters)  tall . 
Fig.  192  Rear seat:

The vehicle's  safety  belts alone  will not  fit  most  children  until 
they  are  at  least  4 ft.  9  in.  (57  inches/1.45  meters)  tall and 
weigh  about  80  lbs. (36  kg).  Booster  seats  raise  these  chil
dren  up  so  that  the  safety  belt  will  pass  properly  over  the 
stronger  parts  of  their  bodies  and  the  safety  belt can help 
protect  them  in  a  crash. 
- Do not  use  the  convertible  locking  retractor  when  using 
the  vehicle's  safety  belt  to restrain  a  child  on  a  booster 
seat. 
- Always  position  the  shoulder  portion  of the  safety  belt 
midway  over  the  child's  shoulder.  If you  must  transport  an 
older  child  in  a  booster seat  on  the  front  passenger seat, 
you  can  use  the  safety  belt  height  adjustment to help 
adjust  the  shoulder  portion  properly. 
- Always  make  sure  that  the shoulder  portion of  the  safety 
belt  never  rests  against  or  across the  child's  neck.

& WARNING 
Rearward-facing  child  restraints: 
• A child  in a  rearward-facing  child safety  seat installed  on the 
front  passenger seat  will  be seriously  injured and  can be killed  if 
the  front  airbag inflates  -even with  an Advanced Airbag  System. 
•  The inflating  airbag  will  hit  the  child  safety  seat  or  infant 
carrier  with  great  force  and will  smash the  child  safety  seat and

•  Always  be especially  careful  if you  must  install  a  rearward 
facing  child  safety  seat on the  front  passenger seat  in exceptional 
circumstances. 
•  A tight  tether  strap  on  a rearward-facing  child  restraint 
attached  to the  front  passenger seat can put  too  much  pressure on 
the  weight-mat  in the  seat  and  register  a  heavier weight  in the 
Advanced Airbag  System.  The heavier weight  registered  can make 
the  system  work  as though  an  adult  were  on the  seat  and  deploy 
the  Advanced Airbag  when  it  must  be  suppressed causing serious 
or even fatal  injury  to  the  child. 
•  Make  sure that  the  PASSENGER AIR  BAG OFF light  comes on 
and  stays on all  the  time  whenever  the  ignition  is switched  on. 
•  If  the  PASSENGER AIR  BAG OFF light  does not  come  on and 
stay  on,  immediately  install  the  rear-facing  child  safety  seat  in  a

fore-and-aft  and  lateral directions,  the brake  pressure  and  the 
steering  angle  are  all  measured. 
The  direction  in which  the  driver  wishes  to  travel is determined  with 
the  aid  of  the  steering  angle  and  vehicle  speed  and  is continually 
compared  with the actual  behavior  of the  vehicle.  If  the  two do not 
match,  for  example , when  the  vehicle  starts  hydroplaning on  a wet 
road,  ESP will  automatically  brake the appropriate  wheel  to correct 
the  problem. 
The  vehicle  is then  stabilized  by the  forces  acting  on  the  wheel  during 
braking.  If  the  vehicle  is 
oversteering (rear  tends  to  skid  out  of  the 
turn),  the  brakes are  mainly  applied  on  the  wheel  that  is on  the 
outside  of  the  curve.  In  the case  of  a vehicle  that  is 
understeering 
(tendency  to  slide  out  of  the  curve),  the  brakes are  applied  at  the  rear 
wheel  that  is  on  the  inside of the  curve.  An acoustic  signal  indicates 
when  ESP brake  application  cuts  in  => 
&. 
The  system  operates  across  the  entire  speed  range  in combination 
with  the  ABS  system=> 
page 246. If  the  Anti-Lock  Brake  System 
(ABS) malfunctions,  the  ESP will  be  out  of  action  as  well. 
Activating 
When  you turn  on the  engine,  ESP will  automatically  be activated  and 
will  perform  a self-test . As soon  as  the  test  is completed,  the  system 
is  in  normal  operating  mode. 
You can  activate  a deactivated  ESP or  deactivated  ESP/ ASR if  required 
by  pressing  the=> 
page 242, fig.  201  button.  When they  are  acti
vated,  the  message 
ESP/ASR on appears  briefly  in  the display . 
Deactivating 
The  ESP  should  normally  be  activated  all  the  time. If necessary , you 
can  deactivate  Anti-Slip  Regulation  (ASR) or  the  Electronic  Stabiliza
tion  Program  (ESP) by pressing  the button => 
page 242, fig. 201. 
•  Deactivating  ASR: Tap  the  but ton . In  certain  excep tional  situa
tions  (e.g. driving  with tire  chains) , the  Anti-Slip  Regulation  (ASR) can 
be  deactivated=> 
page 244 . The  message ASR off appears  in the 
display  as  well. 
Controls  and  equip ment  Safety  first  Vehicle  operation  • 
Deactivating  ESP/ASR 
Press  the  button  for  more  than  3 seconds . 
With  the  ESP/ASR deactivated,  the  ESP check light  comes  on,  see

page  14. The  message ESP switched  off appears  in the  display  as 
well. 
& WARNING 
The Electronic Stabilization  Program is nevertheless  subject  to the  laws  of  physics.  It  is  particularly  important  to  pay attention  to 
this  fact  on wet  and  slippery  roads.  It  is  therefore  important  that 
you  always  adapt  your driving  to  the  condition  of the  road and  traffic  conditions.  Do not  allow  the  increased  safety  provided  by 
the  Electronic  Stabilization  Program system  to  lull you  into 
accepting  additional  safety  risks. • 
Electronic  differential  lock  (EDL) 
The electronic differential lock monitors  the  rotational 
speed  of  the  drive  wheels. 
General  notes 
The electronic  differential  lock  (EDL)  helps  the car  to  start  moving, 
accelerate  and  climb  a  gradient  on  surfaces  providing poor  or  almost 
no  grip . Without  EDL, this  would  be  difficult, if not  impossible . 
How  the  system  works 
The EDL operates  automatically . It  monitors  the  rotational  speed  of 
the  drive  wheels  on  an  axle  with  the  help  of  the  ABS sensors 
=> 
page 246 . If a  noticeable difference  in rotational  speed between 
the  drive  wheels  on  one  axle  is detected  (e.g.  on  slippery  ground 
on 
one side), 
the  spinning  wheel  is braked,  thereby  transferring  power  to 
the  othe r drive  wheel  or wheels  (all-wheel  drive).  This  is done  up  to  a 
speed  of  about 60 mph  (100  km/h) . Noises  from  the  brake  system 
signal  that  wheel  spin  is  being  controlled.

Driv ing  off 
When  driving  off,  always  be  sure  to  keep  road  conditions  in  mind  as 
you  acce lerate.  If one  d rive w heel  spins  because  it  is on  a surface  with 
less  grip,  gradua lly  inc rease  the  press ure  on  the  accelerator  pedal 
un til the  car  sta rts  to  move . 
Overheating  of  brakes 
To prevent  the  disc  brake  of  the  braked  wheel  from  overheating  if 
subjected  to  excessive  loads  o n this  whee l, t he  EDL cuts  out  tem po
ra rily. The  vehicle  rema ins operat iona l a nd  be haves  in the  same  way 
as  a  ve hicle  wit hout  EDL. 
As  soon  as  the  bra ke  has  coo le d  down , ED L swit ches  on  again  au to
matically. 
& WARNING 
•  When  accelerating  on slippery  surfaces , such as on i ce or snow , 
alway s be careful  when  depre ssing  the  accelerator  pedal.  Even 
with  the  EDL work ing , the  drive wheels  can spin and  reduce your 
ability  to  control  your  car.  Risk of  crash! 
•  The  increased safety  afforded  by EDL does  not  mean  that  you 
can take  safety  ri sks . Always  adapt  your  driving  style  to  the  road 
conditions  and  traffic  situation. 
(I) Tips 
If  a  fa ult  occurs  i n the  ABS, the  EDL is also  not  f unct io ni ng . This  is 
indic ated  by t he A BS war ning  ligh t=>

Anti-Slip  Regulation  System  (ASR) 
The  Anti- S lip Re gula tio n Sy stem  preven ts  the  dr iven 
w heels  from  spin ning  w hen  t he car is accelerating . 
General  notes 
The Anti-S lip  Reg ulation  Sys tem  (AS R)  is  in tegr ate d in the  ele ctroni c 
stabilization  program  (ESP) . When  the  ve hicle  starts  up  and  acceler
at es,  the  whee ls are  p reven ted  from  sp inning  by adjust ing  t he engine 
power  to  match  the  amount  of  grip  avai lable  from  the  road  surface. 
How  the  system  works 
ASR performs  automatically,  i.e.  witho ut  the  driver 's  intervent ion. 
W ith  the  a id of t he ABS  sensors=> 
page 246, ASR moni to rs the  speed 
of  the  dr iven  wheels.  If  the  wheels  start  to  spin , th e engine  torque  is 
redu ced  a utomatically  unti l the  t ires  find  enou gh  gr ip  to  lock  onto 
the  road  surface.  T he  system  is active  across  the  entire  speed  range . 
Th e ASR works  in conjunction  with  the  ABS. If  a  malfunction  sho uld 
occ ur  in th e ABS, th e AS R w ill  also  be  out  of  action. 
Activating 
The  ESP is automatically  activated  whe n the  engine  is started  and  it 
performs  a se lf-test.  You can  act ivate  a  deact ivate d ASR if required  by 
press ing  the=> 
pag e 242, fig.  201  button.  Whe n it  is act ivated,  t he 
message 
ESP/ASR on appears  briefly  in t he disp lay.  Vehicles  with 
front-wheel  d rive a dea ct iva te d  ASR a uto mat icall y re-ac tiva tes  i tself 
at  a  speed  of  40  mp h (70  km/h) . 
Deactivating 
You can deact ivate  t he ASR if required  by  pressing  t he button  (for  less 
t han  3 se conds) => 
page 242, fig . 2 0 1. Wi th the  ASR dea ct ivated,  the 
ESP check  light  comes  on,  see=> 
page 14. The  message ASR off 
appe ars  i n the  di sp la y as  wel l. On vehicles  wi th fro nt-whee l dr ive: 
deactivation  is possible  only  up  to  30  mph  (SO km/h)  for  safety 
reas ons.  Vehi cles  w ith  all -wheel  drive:  the  AS R can  be  deac tivated  at 
any  speed.  ..
