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   occurs,
 s

ignalled   by   the   illumination   of   one   or   both
 w

arning   lamps   in   the   instrument   panel,   then
 s

tability   of   the   vehicle   is   no   longer   guaranteed.
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
 
this
 
procedure
 
to
 
reactivate

Reactivation

Deactivating automatic operation
In some situations, such as very cold weather o r   towing   (caravan,   recovery),   it   may   be

The
  hill   start   assist   system   cannot   be

stationary, the vehicle is held momentarily
when you release the brake pedal:

On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held momentarily when you
release the brake pedal.

Parking the vehicle
In all circumstances, ensure that the gear   selector   is   in   position   P before
