2008.5 Citroen JUMPER parking brake

Starting and stopping
HILL START ASSISTANCE
This function, linked with the ESP, makes hill
starts easier and is activated in the following
conditions:
- the vehicle must be stationary, engine running, foot on the brake,
- the gradient of the road must be steeper than 5 %,
- uphill, the gearbox must be in neutral or in a gear other than reverse,
- downhill, reverse gear must be engaged.
The HHC (Hill Holder Control) or Hill Start
Assistance function is a driving comfort
feature. It is not an automatic vehicle
parking function or an automatic handbrake. Operation
With the brake pedal and clutch pedal
pressed, from the time you release the brake
pedal you have approximately 2 seconds
before the vehicle starts to roll back and
without using the handbrake within which to
move off.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the typical noise of mechanical
disengaging of the brakes can be heard,
indicating the imminent movement of the
vehicle.
Anomaly
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.

Driving safety
DRIVING SAFETY
HANDBRAKE HAZARD WARNING LIGHTS
Press this button, the direction indicators
flash.
They can operate with the ignition off.
The hazard warning lights should only be
used in dangerous situations, when stopping
in an emergency or when driving in unusual
conditions.
Applying
Pull the handbrake to immobilise your
vehicle.
Check that the handbrake is applied firmly
before leaving the vehicle. If the handbrake is still on or
has not been released properly,
this is indicated by this warning
light which comes on on the
instrument panel.
When parking on a slope, direct your wheels
towards the pavement and pull the handbrake.
There is no advantage in engaging a gear
after parking the vehicle, particularly if the
vehicle is loaded.
Releasing
Pull the handle and press the button to lower
the handbrake.

Towing a trailer
ACCESSORIES

Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.
Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 9) and of
the trailer, observing the recommended
pressure.
We recommend the use of original
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
If this equipment is not fitted by a
CITROËN dealer, it is imperative that it is
fitted using the electrical pre-equipment
installed at the rear of the vehicle and
in accordance with the manufacturer ’s
instructions.
Good practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.

Side wind: sensitivity to side wind
is increased. Drive smoothly and at a
moderate speed.

ABS: the system only controls the vehicle,
not the trailer.

Rear parking assistance: the assistance
does not function while the vehicle is towing.
