If a malfunction of the system
occurs, this warning light comes
on accompanied by an audible
signal and confi rmed by a
message on the display. Contact a CITROËN
dealer to have the system checked.
The hill start assistance is deactivated in the
following situations:
- when the clutch pedal is released,
- when the handbrake is applied,
- when the engine is switched off,
- when the engine stalls.

ADDITIONAL HEATING SYSTEMS
Supplementary heating
On the 2-3 seats version, this is located
under the seat on the driver ’s side with air
diffusion directed forwards.
REAR HEATING AND/OR AIR CONDITIONING
If your vehicle is fitted with an
additional air conditioning unit,
located in the rear of the vehicle:
the distribution rail located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from
the front air conditioning unit, is distributed
at the feet of the rear passengers of
rows 2 and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
Additional heating
This is an additional passenger compartment
heating system which supplements the
standard equipment.
It can operate independently of the engine.
Depending on the level of finish of the
equipment, its start-up can be programmed.
Additional heater or programmable heating
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance and that of the heated seats, if
fitted in the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The diode
is lit if the heating is activated.
When rapid de-icing and
demisting is required, switch off the control.

Cancelling the programming
Press this button briefly to clear
the programmed start time. The display lighting and the
pre-selection number (e.g. 1) are
switched off.
Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator light is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use recommended replacement parts only.
Recalling one of the pre-selected start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the display remain lit.
Switching off the heating
Press this button.
The heating cycle indicator light
and the display are switched off.
Two different types of equipment
The additional heating is autonomous and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, de-icing and demisting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

Driving safety
TRACTION CONTROL (ASR) AND DYNAMIC STABILITY CONTROL (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration.
Use the ESP to hold your course without
attempting to countersteer. If there is a variation between the trajectory
followed by the vehicle and that required
by the driver, the ESP system automatically
acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
In certain exceptional conditions (when
starting a vehicle stuck in mud or snow, or
on loose ground...), it could prove useful to
disarm the ASR system to make the wheels
spin and regain grip.
Operation of the ASR and ESP systems
The luminous diode flashes when
the ASR or ESP is triggered.
Press this button.
The diode on the button comes on: the
ASR system no longer acts on the engine
operation, but continues to act on the brakes.
MALFUNCTION
When a malfunction of the ASR
system occurs, this warning light
comes on, accompanied by an
audible signal and confirmed by a
message on the display.

Improved safety and security
IMPROVED SAFETY AND SECURITY
IMPACT RESISTANCE
The Jumper has been designed to limit
the forces on the passenger compartment
as much as possible in the event of a
collision, the engine compartment adopts
a progressive deformation structure and
the front doors have been reinforced to
contribute to the rigidity of the whole.
ANTI-THEFT PROTECTION
The Jumper van comprises two zones with
separate locking: the cab and the load space.
Depending on the way in which it is used, this
function provides increased protection both
for your personal belongings and for your
merchandise.Details of these functions are given in
part 2. An exterior protection alarm with anti-lift
detection is available (as standard or as an
option) in certain countries.
