2008 Citroen JUMPER check engine

CHECKS
Air filter and passenger
compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the "Under the
bonnet" section of chapter 7.
Manual gearbox
Have the level checked in accordance with
the manufacturer ’s servicing schedule. To check the main levels and certain
components, in accordance with the
manufacturer ’s servicing schedule, refer
to the pages of the servicing booklet which
correspond to your vehicle’s engine.
Only use products recommended by
CITROËN or products of equivalent quality
and characteristics.
In order to optimise the operation of units as
important as the braking circuit, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
Handbrake
Where the handbrake travel is too great
or there is a reduction in the performance
of the system, the handbrake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer.
Bleeding the water contained in
the diesel filter
If this warning light comes on,
bleed the filter, otherwise bleed
regularly each time the engine is
drained.
To evacuate the water, unscrew the bleed
screw or the water in diesel sensor, located
at the base of the filter. Operate until all
of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer.
Battery
At the start of winter, have your battery
checked by a CITROËN dealer.
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the circuit, a drop
in the brake fluid level indicates that the
brake pads are worn.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer.
Oil filter
Change the filter regularly, in accordance
with the servicing schedule.

Low fuel level
When the fuel tank level E
(Empty) is reached, this warning
light comes on. At this moment,
you have enough fuel left to
drive approximately 30 miles (50 km) ,
depending on the driving conditions, the
engine and the profile of the road. Fill up
without delay to avoid running out of fuel. The fuel tank must be fi lled
with the engine off .
- Open the fuel filler flap.
- Support the cap with one hand.
- With the other hand, insert the key, then turn it anticlockwise.
- Remove the cap and hook it onto the clip located on the inside of the flap.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle. This could
cause malfunctions.
The capacity of the fuel tank is
approximately 90 litres.
- After filling the fuel tank, lock the cap and close the flap.
FUEL CIRCUIT DEACTIVATED
In the event of a serious collision, a device
automatically cuts off the fuel supply
to the engine and the vehicle’s electrical
supply.
FILLING WITH FUEL
Fuel tanks of different capacities,
60 and 125 litres, are sold. Check that there is no smell or leak of fuel
outside the vehicle.

CHARGING THE BATTERY USING
A CHARGER
- disconnect the battery,
- follow the instructions for use given by
the battery charger manufacturer,
- reconnect starting with the negative (-) terminal,
- check that the terminals and connectors are clean. If they are covered with
sulphate (white or greenish deposit),
disconnect them and clean them. The charging operation must be carried
out in a ventilated area away from naked
flames or any possible sources of sparks to
eliminate the risk of explosion and fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
