Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
–

Anti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Post Collision Safety Brake (PCSB).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
Anti-lock braking system (ABS)/Electronic brake force
distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
Electronic brake force distribution (EBFD)
manages overall braking pressure on each
individual wheel.
►

When braking in an emergency
, depress
the pedal very firmly and maintain this
pressure.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
The fixed illumination of this warning lamp signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp, when lit together with the STOP and ABS warning lamps,
accompanied by a message and an audible
signal, indicates an EBFD malfunction.
You must stop the vehicle.
Stop as soon as it is safe to do so and switch off
the ignition.
Contact a CITROËN dealer or a qualified
workshop.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact
Have it checked by a CITROËN dealer or
a qualified workshop.
Post Collision Safety Brake
(PCSB)
If an accident is detected, the vehicle initiates
automatic post collision braking. The goal of this
system is to reduce the risk of further collisions if
the driver does not react.
The system is not operational if the capability
of the vehicle is to trigger and execute the

70
Safety
automatic post collision braking is not available,
as it can occur in destructive accidents or in
other specific accident scenarios.
It is possible to override the automatic braking by
pressing the brake pedal or accelerator pedal.
Operating conditions
The system operates, if the following conditions
are met:
–
Airbags or pyrotechnic seat belt pretensioners
have been deployed by the collision.
–


Braking systems and electric functions remain
continuously operational during and after
collision.
–


Driver has not depressed the brake or
accelerator pedal.
Malfunction
In the event of a
malfunction, one of these
warning lamps will come on fixed on the
instrument panel, accompanied by the Service
warning lamp, the display of a message and an
audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
This system reduces the emergency stopping
distance, by optimising the braking pressure. It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
/ Dynamic stability control
(DSC)
Anti-slip regulation (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
These systems are activated in the event of a problem with grip or trajectory
(confirmed by this warning lamp flashing on the
instrument panel).
Deactivation/Reactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system as soon as the level of
grip permits.
This function is set via theDriving/Vehicle touch screen menu.
Deactivation is confirmed by the lighting
of this indicator lamp on the instrument
panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched off, or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp comes on on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels

84
Driving
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►

Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
►


Drive smoothly
, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
►

Stop the vehicle before performing operations
that require sustained attention (e.g.

settings).
►

During long trips, take a break every 2 hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damaging the braking system!
Never park the vehicle and never
leave the engine running on a
flammable surface (e.g.
dry grass, dead
leaves).The vehicle exhaust system is very
hot, even several minutes after the engine
stops. Risk of fire!
Never drive on surfaces covered with
vegetation (e.g. tall grass,
accumulated dead leaves, crops, debris)
such as a field, a country lane overgrown
with bushes or a grassy verge.
This vegetation could come into contact with
the vehicle's exhaust system
or other systems
which are very hot. Risk of fire!
Make sure you do not leave any item in
the passenger compartment which could
act like a magnifying glass under the effect of
the sun's rays and cause a fire. Risk of fire or
damage to interior surfaces!
Never leave the vehicle unattended,
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).
Never leave children inside the vehicle
unsupervised.
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 your vehicle's
electrical systems.


If the vehicle absolutely must drive through a
flooded section of road:
►

Check that the depth of the water does not
exceed 15

cm, taking account of waves that
might be generated by other users.
►

Deactivate the Stop & Start function.
►


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 off the engine.
On leaving the flooded road, as soon as safety
conditions 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.

Driving
6Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when
driving, the driver must pay particular attention.
When manoeuvring, the driver must always
check the vehicle's immediate surroundings.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during
charging to cool the on-board charger and the
traction battery.
On the inside
During use, you may hear certain perfectly
normal noises specific to electric vehicles, such
as:
–

T
raction battery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
–

Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
