HILL START ASSIST
This system (also called HHC - Hill Holder
Control), linked to the dynamic stability
control system, 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 Hill Start Assist function is a driving
aid system. It is not an automatic vehicle
parking function or an automatic parking
brake. 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 parking brake within which
to move off.
During the moving off phase, the function
is deactivated automatically, gradually
releasing the braking pressure. During
this phase, the characteristic noise of
mechanical release of the brakes may be
heard, indicating the imminent movement of
the vehicle.
Operating fault
If a malfunction of the system
occurs, this warning lamp comes
on accompanied by an audible
signal and confi rmed by a message
in the screen. Have the system checked by at
a CITROËN dealer or a qualifi ed workshop. Hill start assist is deactivated in the following
situations:
- when the clutch pedal is released,
- when the parking brake is applied,
- when the engine is switched off,
- when the engine stalls.

READY TO GO
Starting and stopping
Going into engine START mode - The "S" warning lamp goes off and the engine restarts.
If following an automatic restart in START
mode, the driver takes no action on the
the vehicle during the next 3 minutes, the
system stops the engine definitively. The
engine can then only be restarted using
the key. Special cases: START invoked
automatically
The START mode is invoked automatically
when:
- the vehicle's is free wheeling on a slope,
- the windscreen wiper is on fast wipe,
- the air conditioning is running,
- the engine has been stopped for around
3 minutes with Stop & Start,
- some special conditions (battery charge, engine temperature, braking assistance,
ambient temperature...) where the
engine is needed to assure control of
a system.
In this case, a message appears
in the instrument panel screen,
accompanied by the "S" warning
lamp, which flashes for a few
seconds, then goes off. Good practice
With a manual gearbox in STOP mode, if a
gear is engaged without fully depressing the
clutch pedal, restarting may not take place.
A warning lamp or message is displayed
in the instrument panel asking you to fully
depress the clutch pedal to allow restarting.
With the engine stopped in STOP mode,
if the driver unfasten's their seat belt and
opens a front door, the engine can only be
restarted using the ignition key. There is an
audible signal, accompanied by flashing of
the "S" warning lamp and, depending on
equipment, a message is displayed.
This operation is perfectly normal.
With the vehicle in gear, automatic engine
restarting is only allowed by fully depressing
the clutch pedal.

Steering mounted controls
CRUISE CONTROL
"This is the speed at which the driver wishes
to drive".
This aid to driving in free-flowing traffic
enables the vehicle to maintain the speed
programmed by the driver, unless a steep
gradient makes this impossible. In order for it to be programmed or
activated, the vehicle speed must be greater
than 25 mph (40 km/h) with at least 4th gear
engaged on the manual gearbox. This cruise control shows the status of the
system in the instrument panel screen and
displays the programmed speed:
Function selected,
displaying of the "Cruise
Control" indicator light.
Function deactivated,
OFF (example at
107 km/h).
Function activated
(example at 107 km/h).
Vehicle speed above
(e.g. 118 km/h),
the programmed speed
is displayed flashing.
Operating fault detected,
OFF - the dashes flash.

Transport solutions
ACCESSORIES
Distribution of loads: distribute the load in
the trailer so that the heaviest objects are as
close as possible to the axle and the nose
weight is close to the maximum authorised
without, however, exceeding it.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
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 and of the trailer, observing
the recommended pressures.
Fitting a towbar
We recommend the use of genuine
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.
These genuine towbars are compatible with
the operation of the rear parking sensors
and the reversing camera, if fitted to your
vehicle.
If this equipment is not fitted by a CITROËN
dealer, it must be fitted in line 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 lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
Refer to the "Checks - Levels and
checks" section.
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 sensors: the system does not
operate while the vehicle is towing.
Refer to the "Technical data -
Identification markings" section.

CHECKS
Levels and checks
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the maintenance and warranty
guide which correspond to your vehicle's
engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.
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.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer or a qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is strictly
prohibited.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes.

Being towed or towing
TOWING
Towing the vehicle
The removable towing eye is located in the
tool box under the front passenger seat.
Unclip the cover using a flat tool.
Screw the removable towing eye in fully.
Attach the approved towing bar to to the
removable towing eye.
Place the gear lever in neutral.
Towing another vehicle
The fixed towing eye is located on the right
below the bumper.
Attach the approved towing bar onto the
fixed eye.
Failure to observe this requirement
may result in damage to certain
braking components and the lack of some
braking assistance systems when the engine
is re-started.
General recommendations
Observe the legislation in force in your
country.
Ensure that the weight of the towing vehicle
is higher than that of the towed vehicle.
The driver must remain at the wheel of the
towed vehicle and must have a valid driving
licence.
When towing a vehicle with all four wheels
on the ground, always use an approved
towing bar; rope and straps are prohibited.
The towing vehicle must move off gently.
When towing a vehicle with the engine off,
there is no longer any power assistance for
braking or steering.
In the following cases, you must always call
on a professional recovery service:
- vehicle broken down on a motorway or fast road,
- four-wheel drive vehicle,
- when it is not possible to put the gearbox into neutral, unlock the
steering, or release the parking brake,
- towing with only two wheels on the ground,
- where there is no approved towing bar available...
