Blind spot sensors
This driving assistance system warns the driver of the presence of another vehicle in the blind
spot
  angle   of   their   vehicle   (areas   masked   from  
t

he   driver's   field   of   vision),   as   soon   as   this  
p

resents   a   potential   danger.
Operation
F On  switching   on   the   ignition,   or   engine  r
unning,   press   this   button   to   activate   the  
f

unction;   the   warning   lamp   comes   on.

Misfuel prevention (Diesel)*Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine   damage   that   can   result   from   filling   with   the   wrong   fuel.
Located
  in   the   filler   neck,   the   misfuel   prevention   device   appears   when   the   filler   cap   is   removed.
When a petrol filler nozzle is introduced into the
fuel
  filler   neck   of   your   Diesel   vehicle,   it   comes  
i

nto   contact   with   the   flap.   The   system   remains  
c

losed   and   prevents   filling.
Do not persist but introduce a Diesel type
filler nozzle.
*
  Depending   on   the   country   of   sale.It
  remains   possible   to   use   a   fuel   can   to  
f

ill   the   tank.
In
  order   to   ensure   a   good   flow   of   fuel,  
d

o not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel
  prevention   device   and   pour  
s

l ow l y.
Travelling abroad
As Diesel fuel pump nozzles may be different in other countries, the
presence
  of   the   misfuel   prevention  
d

evice   may   make   refuelling   impossible.
Not all Diesel vehicles are fitted with
misfuel
  protection,   so   before   travelling  
a

broad,   we   recommend   that   you   check  
w

ith   the   CITROËN   dealer   network,  
w

hether your vehicle is suitable for the
fuel
  pumps   in   the   country   in   which   you  
i

ntend   to   travel.

Checking levels
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.
Engine oil level
Checking using
the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
It
  is   normal   to   top   up   the   oil   level   between  
t

wo   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   kms).A = MA X
B = MIN If you find that the level is above the A
  mark   or  
belo

w the B   mark,   do not star t the engine.
-

I
f the level is above the MAX
 
mark   (risk  
o

f   damage   to   the   engine),   contact   a  
C

ITROËN   dealer   or   a   qualified   workshop.
-

I
f the level is below the MIN
 
mark,   you  
m

ust   top   up   the   engine   oil.
Oil grade
Before topping-up the oil or changing the oil, check   that   the   oil   is   the   correct   grade   for   your  
e

ngine   and   conforms   to   the   manufacturer's  
r

ecommendations.
Take
