You can deactivate the ASR
and DSC systems by turning
the knob to the "OFF" position.
Recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road
driving such as:
-

c

rossing and driving on terrain which
could damage the underbody or strip
away components (fuel pipe, fuel
cooler, etc.) due to obstacles or stones
in particular,
-

d

riving on terrain with steep gradients
and poor grip,
-

c

rossing a stream.Hill Assist Descent
Control
System that provides assistance when
descending on loose or soft sur faces (gravel,
mud, etc.) or a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle when descending,
whether going forward or in reverse.
During a
descent, it assists the driver in
maintaining a


constant speed, depending
on the gear engaged, while progressively
releasing the brakes.
For the system to activate, the slope must
be greater than 5%.
The system can be used with the gearbox
in neutral.
Otherwise engage a


gear corresponding
to the speed to prevent the engine stalling.
With an automatic gearbox, the system
can be used with the selector at N , D or R.
When the system is regulating, the Active
Safety Brake system is automatically
deactivated. The system is not available:
-

i
f the speed of the vehicle is above
43 mph (70 km/h),
- i f the speed of the vehicle is being
controlled by the Adaptive Cruise
Control, depending on the type of
gearbox.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the
ignition is switched off.
The driver can select the system when
the engine is running, when the vehicle is
stationary or when moving at speeds up to
approximately 31
mph (50 km/h).
The ASR and DSC systems will no longer
act on the engine operation or the brakes
in the event of an involuntary change of
trajectory.
These systems are reactivated
automatically from 31

mph (50

km/h) or
every time the ignition is switched on.

of f.Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a
gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver's door is closed.Do not leave the vehicle while it is being
held in the hill start assist phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually. Then check that the parking
brake warning lamp is on fixed on the
instrument panel.
The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.

Malfunction
Gear efficiency indicator
(Depending on engine.)
This system reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears.
Gear engagement recommendations are
only optional. In fact, the configuration of the
road, the traffic density and safety remain
determining factors when choosing the best
gear. Therefore, the driver remains responsible
for deciding whether or not to follow the
system's advice.
This function cannot be deactivated.With an automatic gearbox, the system is
only active in manual operation.
The information appears in the
instrument panel in the form of an
arrow and the recommended gear.
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 Stop & Start function puts the engine
temporarily into standby – STOP mode – during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
– START mode – as soon as the driver wishes
to move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities
of the vehicle, in particular the braking.

pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a
drop in the inflation pressure of one
or more tyres.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need
to regularly check the tyre pressures
(including the spare wheel) as well as
before a


long journey.
Driving with under-inflated tyres,

Misfuel prevention (Diesel)
(Depending on country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol.
Operation
Until sufficient fuel is added, this warning lamp
reappears every time the ignition is switched
on, accompanied by the message and the
audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 0 .
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel) , refer to the corresponding section. entirely normal and results from the sealing of
the fuel system.
Practical information

181
It remains possible to use a fuel can to fill
t he tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with a
CITROËN dealer whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
When a
petrol filler nozzle is introduced into
the fuel filler neck of a Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Compatibility of fuels
The use of any other type of (bio) fuel
(vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.
Diesel fuels conforming to the EN590,
EN16734 and EN16709 standards respectively
and containing up to 7%, 10%, 20% and 30%
fatty acid methyl ester respectively. The use of
B20
or B30 fuels, even occasionally, imposes
special maintenance conditions referred to as
"Arduous conditions".
Paraffinic Diesel fuel conforming to the
EN15940

standard.
Diesel at low temperature
At temperatures below 0°C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50% full.
At temperatures below -15°C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Cer tain fuels could damage your vehicle's
engine.
In cer tain countries, the use of a
par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For all additional information, consult a


dealer.
