Emergency braking
In the event of a failure of the main service brake   or   in   an   exceptional   situation   (e.g.   driver  
t

aken   ill,   under   instruction,   etc)   a   continuous  
p

ull   on   the   control   lever   will   brake   the   vehicle.  
B

raking   takes   place   while   the   control   lever   is  
b

eing   pulled.   It   is   interrupted   if   the   control   lever  
i

s
 r
eleased.
The
  ABS   and   DSC   systems   provide   stability   of  
t

he   vehicle   during   emergency   braking.
If
  the   emergency   braking   malfunctions,   the  
m

essage   "Parking   brake   control   faulty"   will   be  
d

isplayed.
If
  a   failure   of   the   ABS   and   DSC   systems  
o

ccurs,   signalled   by   the   illumination   of   one  
o

r   both   warning   lamps   in   the   instrument  
p

anel,   then   stability   of   the   vehicle   is   no   longer  
g

uaranteed.
In
  this   event,   stability   must   be   assured   by   the  
d

river   by   repeating   alternate   "pull-release"  
a

ctions on the control lever until the vehicle is
immobilised. The
  emergency   braking   should   only   be  
u

sed   in   an   exceptional   situation.
Repeat
