Driving recommendations
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.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
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.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a
risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4
minutes before driving.
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.
Important!
If you are obliged to drive through water:
- c heck that the depth of water does not
exceed 15
cm, taking account of waves that
might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without stalling.
Under no circumstances exceed 6
mph
(10


km/h),
-

d
o not stop and do not switch off 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 about the state of your vehicle,
contact a
CITROËN dealer or a qualified
workshop.
Never drive with the parking brake
applied – risk of overheating and damage
to the braking system!
Do not park and do not run the engine
with the vehicle stationary, in areas where
substances and combustible materials
(dry grass, leaves, etc.) can come into
contact with the hot exhaust system – risk
of fire!
Never leave a vehicle unsuper vised 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 or position N or P , depending on
the type of gearbox.
To assure the durability of your vehicle and
your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle:

Driving

88
Manoeuvre cautiously, at low
speed
The dimensions of your vehicle differ from
those of a light vehicle, in width, in height, as
well as in length, and some obstacles will be
more difficult to notice.
Manoeuvre slowly.
Before turning, check that there are no
obstacles at mid-height along the sides.
Before reversing, check that there are no
obstacles, particularly at high level behind the
vehicle.
Be aware of the external dimensions, if ladders
are fitted.
Load the vehicle correctly
With a load, the vehicle must remain within the
m aximum authorised weight, the Gross Vehicle
Weight.
To avoid upsetting the balance of the vehicle,
the load should be centred and the heaviest part
placed on the floor in front of the rear wheels.
It is inadvisable to place heavy loads on a
roof
rack.
Loading also implies adherence to the
maximum load of the roof bar anchor points.
Adhere to the maximum permissible weight,
according to CITROËN dealer specifications.
Loads must be securely lashed down.
A load that is not properly secured inside the
vehicle may affect vehicle handling and create
a
risk of accident.
Drive the vehicle in a prudent
a nd efficient way
Take corners gently.
Anticipate the need to brake as the stopping
distance is increased, particularly on wet or icy
roads.
Be aware of the effect of side winds on the
vehicle.
Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance
so that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2
to 0.3 bar for long journeys.
In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
Side wind
F Take into account the increased sensitivity to wind.
If your vehicle is fitted with a

drop-side back,
the height and width of the load must remain
within the overall dimensions of the vehicle.
Driving

89
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a
trailer before having driven at
least 620
miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a
genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system.
It activates automatically when the key is
removed from the ignition.
This warning lamp goes off after the
key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key
and have the faulty key checked by
a
CITROËN dealer.
Note the number of the keys carefully; in
case of loss, inter vention by the CITROËN
dealer will be more efficient and quicker
if you present this number and the
confidential card.
When the ignition switch is turned on, a
dialogue is set up between the key and the
electronic immobiliser.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms, etc.), may inter fere
with the operation of the remote control
temporarily.
The remote control does not operate
while the key is in the ignition, even if the
ignition is off, except for reinitialisation.

Releasing
When the vehicle is being driven,
this warning lamp coming on
indicates that the parking brake is
still applied or has not been fully
released.
Manual gearbox
To change gear easily, always depress the
clutch pedal fully.
To prevent the mat from becoming caught
under the pedal:
-
e
nsure that the mat is positioned
correctly,
-

n
ever fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear the
internal components of the gearbox over time.
Engaging reverse gear
Never engage reverse gear before the
vehicle is completely stationary.
If your vehicle is fitted with parking
sensors, the system comes into operation
when reverse gear is engaged; an audible
signal is heard.
For more information on Rear parking
sensors , refer to the corresponding
section.
F

P

ull the lever up slightly and press the
button to release the parking brake lever.
Gear efficiency indicator
Depending on the engine or model, this system
allows fuel consumption to be reduced by
suggesting when to change up.
Gear efficiency recommendations are only
optional. In fact, the road configuration,
the traffic density and safety remain the
determining factors when choosing the best
gear. Therefore, the driver remains responsible
for deciding whether or not to follow the
system's advice.
The system cannot be deactivated.
Operation
The information appears in the
instrument panel screen in the form
of the SHIFT indicator, accompanied
by an upward arrow to signal to the
driver that they can change up.
The system adapts its gear shift
recommendation according to the driving
conditions (slope, load, etc.) and the
driver's requirements (power, acceleration,
b r a k i n g , e t c .) .
The system never recommends engaging
first gear or reverse, or changing down.
F

R

aise the collar under the gear knob to
engage reverse gear.
The lever should be moved slowly to reduce the
noise on engaging reverse gear.
Driving

93
Stop & Start
The Stop & Start system puts the engine
temporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams, etc.).
The engine restarts automatically – START
mode – as soon as you wish to move off.
Restart is instantaneous, quick and silent.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions and offers the comfort of complete
silence when stationary.
Going into engine STOP
mode
With the vehicle stationary, put the gear lever
into neutral, then release the clutch pedal.This indicator lamp comes on in the
instrument panel and the engine
goes into standby.
Automatic stopping of the engine is only
possible after the vehicle has exceeded
a
speed of about 6 mph (10 km/h), to avoid
repeated stopping of the engine when
driving slowly. Never leave your vehicle before turning off
the ignition with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
using the key.
Special cases: STOP mode
not available
STOP mode is not triggered when:
-
t he system is initialising,
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he air conditioning is on,
-

t
he rear screen demisting is on,
-

t
he windscreen wipers are on fast wipe,
-

r
everse gear is engaged for a parking
manoeuvre,
-
s

ome special conditions (battery charge,
engine temperature, particle filter
regeneration, braking assistance, exterior
temperature, etc.) where the engine is
needed to assure control of a
system.-

d
uring intensive use of Stop & Start, it
may be deactivated to conser ve starting
ability; go to a CITROËN dealer to have the
function reactivated.
This indicator lamp in the instrument
panel flashes for a few seconds,
then goes off.
This operation is perfectly normal.
Going into engine START
mode
With the vehicle in gear, automatic engine
restarting is only allowed by fully depressing
the clutch pedal.
This indicator lamp goes off and the
engine restarts.
If the driver takes no action on the vehicle for
3
minutes after an automatic restart in START
mode, the system stops the engine definitively.
The engine can then only be restarted using
t h e key.

Fuel system cut-off
In the event of a collision, a device
a utomatically cuts off the fuel supply to the
engine and the vehicle's electrical supply.
It switches on the hazard warning lamps and
the courtesy lamps, as well as unlocking the
doors.
Following an impact and before restoring
the supply, check that there is no leak of
fuel or sparks so as to avoid any risk of
fire.

Brake disc wear
For information on checking brake
disc wear, contact a CITROËN or
a


qualified workshop.
Parking brake
If excessive travel or a loss of
e ffectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a
CITROËN
dealer or a
qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reser voir. If this warning lamp comes on, the
filter must be purged to remove
water.
You can also purge the fuel filter
regularly, every time the engine oil
is changed.
Purging water from the filterThe HDi engines use advanced technology.
All work must be done by personnel that
have had special training, which can be
ensured by going to a
CITROËN dealer or
a


qualified workshop.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
