Starting and stopping


HILL START ASSIST

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
Assist function is a driving comfort 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 typical noise of mechanical
release of the brakes can 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 on the screen. Contact a CITROËN
dealer to have the system checked. 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.

Driving safely
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 deactivate the ASR system to make the
wheels spin and regain grip.

Operation of the ASR and ESP
systems
The LED flashes when the ASR
or ESP is triggered. Press this button.
The LED on the button comes on: the ASR
system no longer acts on the engine operation,
but continues to act on the brakes.
Operating fault

When a malfunction of the ASR
system occurs, this warning lamp
comes on, accompanied by an
audible signal and confirmed by a
message on the screen.

Towing a trailer

ACCESSORIE
S


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
markings" section of chapter 9) and of
the trailer, observing the recommended
pressures.
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 lamp 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

sensors

:
the system does not
operate while the vehicle is towing.
