Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep
your hands on the wheel so that you are
ready to react at any time to any eventuality.
On a long journey, a break every two hours
is strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.
driving on flooded roads
We strongly advise against driving on
flooded roads, as this could cause serious
damage to the engine or gearbox, as well as
to the electrical systems of your vehicle. If you are obliged to drive through water:
-

check that the depth of water does not

exceed 15 cm, taking account of waves
that might be generated by other users,
-
deactivate the Stop & Start system,
-

drive as slowly as possible without

stalling. In all cases, do not exceed
6 mph (10 km/h),
-

do not stop and do not switch of
f the
engine.
On leaving the flooded road, as soon as
circumstances allow, make several light
brake applications to dry the brake discs
and
pads.
If in doubt on the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
Important!
Never drive with the parking brake applied -
Risk of overheating and damage to the
braking system!
Do not park or run the engine when
stationary in areas where inflammable
substances and materials (dry grass, dead
leaves...) might come into contact with the
hot exhaust system - Risk of fire!
Never leave a vehicle unsupervised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral.
Starting and switching off

74
Have the additional heating checked at
least once a year at the beginning of
winter. Maintenance and repairs should only
be carried out by a CITROËN dealer or a
qualified workshop.
Use only genuine replacement parts.
Switching off the heating
In the case of deferred operation, the
heating stops at the end of the programmed
period.
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 switches off when the
battery voltage is low, so as to allow engine
starting.
The additional heating is supplied by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion. 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 is fitted with
a temperature limiter which cuts off
the combustion in the event of engine
overheating due to a lack of coolant. Check
the level and if necessary top-up following
the advice given in the "Checks - Levels"
section. Then press the programme
selection button before switching the heating
on again.
Setting the operating period
The period of operation can be set to
between 10 and 60 minutes.
Press and hold the "set" button.
At the same time press the "<"
or ">" button.
The time and the time setting
indicator come on.
Press and hold the "set" button again.
At the same time press the "<" or ">" button
again.
The programmed operating period is
displayed and the heating or ventilation
cycle indicator flashes.
Adjust the period by pressing the "<" or ">"
button.
The setting is confirmed by the period
disappearing from the screen or by pressing
the "set" button again In the case of immediate
operation, press this button
again
to switch off manually.
The heating cycle indicator and
the screen go off.

Hill descent control
System that provides assistance when
descending on surfaces with poor grip (mud,
gravel...) or on a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle while descending
a hill.
It keeps the vehicle at a steady speed during
a descent by acting independently and with
varying force on each of the brakes. Switching off
Press this button, located in the middle of the
dashboard, to deactivate the system; the indicator
lamp in the button goes off.
Above 30 mph (50 km/h), the system is completely
deactivated; the indicator lamp in the button goes off.
Operating fault
If a fault occurs with the hill
descent control system, this
warning lamp comes on.
Have the system checked by a CITROËN
dealer or a qualified workshop.
Switching on
On starting the vehicle, the system is
deactivated.
With the speed below 18 mph (30 km/h)
press this button, located in the middle of
the dashboard, to activate the system; the
indicator lamp in the button comes on.
Once the vehicle starts its descent, you can
release the accelerator and brake pedals;
the indicator lamp in the button flashes.
The brake lamps come on automatically
when the system is brought into operation.
If the speed of the vehicle exceeds 18

mph
(30 km/h), the system is automatically
deactivated, but the indicator lamp in the
button stays on.
The system reactivates automatically as
soon as the speed of the vehicle drops
below 18 mph (30 km/h).
For the system to operate, the slope
must be steeper than 8%.
Do not use the system with the gearbox in
neutral.
Engage an appropriate gear for the speed of
the vehicle, to avoid the engine stalling.
You can press the accelerator or brake
pedal at any time. The system may not be available if the
brakes overheat. Wait a few minutes
for them to cool down before trying again.
