Checking levels
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.
Engine oil level
It is normal to top up the oil level between two 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).
The
check is carried out either when
t
he ignition is switched on using the
o
il level indicator in the instrument
p
anel for vehicles so equipped, or
u
sing the dipstick.
To ensure that the reading is correct,
y
our vehicle must be parked on a level
s
ur face with the engine having been off
f
or more than 30 minutes.
Take care when working under the
b
onnet, as certain areas of the engine
