 The  ESP/ASR  systems  offer  ex- 
ceptional  safety  in  normal  driving, 
but  this  should  not  encourage  the 
driver to take extra risks or drive at 
high speed.  
 The  correct  functioning  of  these  
systems  depends  on  observation 
of  the  manufacturer’s  recommen-
dations regarding the wheels (tyres 
and rims), the braking components, 
the electronic components and the 
CITROËN assembly and operation 
procedures.  
 After an impact, have these systems  
checked by a CITROËN dealer.   
   Deactivation  
 In exceptional conditions (starting a ve- 
hicle  which  is  bogged  down,  stuck  in 
snow,  on  soft  ground...),  it  may  be  ad-
visable to deactivate the ASR and ESP 
systems,  so  that  the  wheels  can  move 
freely and regain grip.     
     Press the   "ESP OFF"   button, locat-
ed in the centre of the dashboard.  
 If  this  warning  lamp  comes  on  in 
the instrument panel and the indi-
cator  lamp  on  the  button  comes 
on, this indicates that the ASR and 
ESP systems are deactivated.  
  Reactivation  
 These systems are reactivated automat- 
ically  each  time  the  ignition  is  switched 
 b a c k   o n   o r   f r o m   3 0   m p h   ( 5 0   k m / h ) .   
   
     Press  the    "ESP  OFF"    button  again 
to reactivate them manually.      Operating fault 
 If  this  warning  lamp  comes  on,  
accompanied by an audible sig-
nal and a message on the mul-
tifunction  screen,  this  indicates 
a malfunction of these systems.  
 Have  the  systems  checked  by  a  
CITROËN dealer. 
           TRAJECTORY CONTROL SYSTEMS  
  Activation  
 These  systems  are  activated  automati- 
cally each time the vehicle is started.  
 They  come  into  operation  in  the  event  
of a grip or trajectory problem. 
  Anti-skid regulation (ASR) and 
electronic stability programme 
(ESP)  
 The anti-skid regulation (also known as  
Traction  Control)  optimises  traction  to 
prevent  skidding  of  the  wheels,  by  act-
ing  on  the  brakes  of  the  driving  wheels 
and on the engine.  
 The electronic stability programme acts  
on the brake of one or more wheels and 
on the engine to keep the vehicle on the 
trajectory required by the driver.
