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!
Do not park the vehicle or 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 automatic
gearbox into position N or P.
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 internal combustion engine or electric motor,
the gearbox and the electrical systems of the
vehicle.


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 motor
.
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
6Towing
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.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.

Driving
6Mode P is automatically selected when
the ignition is switched off. The wheels
are blocked.
For more information on Free-wheeling, refer
to the corresponding section.
While mode N is selected, opening the
driver’s door triggers an audible signal
and selection of mode P.
The audible signal stops when the driver's
door is closed.
Deactivating automatic
operation
In some situations, for example when it is
extremely cold or when towing (e.g. caravan,
breakdown), it may be necessary to deactivate
automatic operation of the system.
►

Start the engine.
►


Use the control to apply the parking brake, if
it is released.
►


T
ake your foot fully off the brake pedal.
►

Keep the control pushed in the release
direction for 10 to a maximum of

15 seconds.
►

Release the control.
►


Depress and hold the brake pedal.
►


Pull the control in the application direction for
2

seconds.
This indicator lamp on the instrument panel comes on to confirm deactivation of
the automatic functions. ►

Release the control and the brake pedal.
From this point onwards, only the manual
functions, using the control, allow the parking
brake to be applied and released.
►

Follow this procedure again to reactivate
automatic operation (confirmed by the indicator
lamp on the instrument panel going out).
Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g.
driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by the
lighting of one or both warning lamps on the
instrument panel, the vehicle’s stability is no
longer ensured.
►

In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions
on the electric parking brake control until the
vehicle comes to a complete stop.
Automatic gearbox
With petrol engine
Automatic 8-speed gearbox with push selector. It also offers a manual mode with gear changes
via control paddles located
behind the steering
wheel.
With rechargeable hybrid
engine

Driving
6If you open the driver's door while mode
N is engaged, an audible signal will
sound and mode P will be selected. The
audible signal stops when the driver's door is
closed.
If the speed drops below 3 mph (5 km/h),
opening the driver's door triggers
selection of mode P - risk of sudden braking!
In the event of battery failure, it is
essential to place the chock(s) supplied
with the tool kit against one of the wheels to
immobilise the vehicle.
Special aspects of automatic mode
The gearbox selects the gear that provides
optimal performance based on ambient
temperature, road profile, vehicle loading and
driving style.
For maximum acceleration, press the accelerator
fully down (kick-down). The gearbox changes
down automatically or holds the selected gear
until the maximum engine speed is reached.
Steering mounted controls allow the driver to
temporarily select a gear, if the vehicle speed
and engine speed conditions permit.
Special aspects of manual mode
The gearbox only changes from one gear to
another if the vehicle speed and engine speed
conditions permit.
Regenerative braking (Brake function)
The regenerative braking function emulates
engine braking, slowing the vehicle with no need
to depress the brake pedal. When the driver
releases the accelerator pedal, the vehicle slows
down more quickly.
The energy recovered when the accelerator
pedal is released is used to partially recharge the
traction battery.
This partial recharging has no effect on the charge level indicator.
The resulting deceleration of the vehicle does not cause the brake lamps to come
on.
►

From
mode D, press button B to activate/
deactivate the function.
D on the instrument panel is replaced with B.
In some situations (e.g. battery full,
extreme temperatures), the amount of
regenerative braking may be temporarily
limited, resulting in less deceleration.
The driver must remain alert to traffic
conditions and must always be ready to use
the brake pedal.
Regenerative braking using the brake
pedal
Energy recovery can also be produced
by depressing the brake pedal in order to
partially recharge the traction battery, without
affecting the charge level indicator.
Starting the vehicle
► Fully depress the brake pedal.
► Start the engine.
►

With your foot on the brake pedal, push once
or twice backwards to select automatic mode D

,
or forwards to shift into reverse gear R.
►

Release the brake pedal.
►


Accelerate gradually to automatically release
the electric parking brake.
The vehicle moves off immediately

.
Never try to start the engine by pushing
the vehicle.
Switching the vehicle off
Regardless of the current gearbox mode, mode
P is immediately engaged automatically when
the ignition is switched off.
However, in mode N, mode P will be engaged
after a delay of 5 seconds (time to enable free-
wheeling mode).
Check that mode P has been engaged and
that the electric parking brake was applied
automatically; if not, apply it manually.
The corresponding indicator lamps on the gear selector and the electric parking
brake control must be on, as well as the
indicator
lamps on the instrument panel.

6Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving 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.
Deactivation/Reactivation
By default, the function is activated when the
ignition is switched on.
It is configured in the ADAS touch screen
application.

Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►

Switch off the ignition then start the engine
again with the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver when one or more
tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes the last values

stored during
the

reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.

103
Driving
6Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30
cm away
from the radar, sensors and cameras.
Mats / Pedals covers
The use of mats or pedals covers not
approved by CITROËN may interfere with
the operation of the speed limiter or cruise
control.
T
o avoid any risk of jamming the pedals:
–

Ensure that the mat is secured correctly
.
–

Never fit one mat on top of another
.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Steering wheel with
hands-on detection
(with Highway Driver Assist 2.0)
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The steering wheel is equipped with a hands-on
detection system to avoid distraction on the part
of the driver.
It is prohibited to cover or attach anything to the
steering wheel.
The driver must always check the surroundings of the vehicle and
supervise the whole manoeuvre.
Any use of a system built into
Highway Driver
Assist 2.0
must remain under the driver’s
vigilance.
The system also detects the presence of
hands when using the Lane Positioning assist
system with Highway Driver Assist.
The system may suffer interference or not work correctly if:
–

the steering wheel is covered by some
protection.
–


the driver wears thick gloves (e.g.
ski
gloves).
In the event of improper detection of hands on
the steering wheel, Highway Driver Assist 2.0
is not activated or is deactivated after a few
seconds.
Installation of mechanical anti-theft
devices on the steering wheel is
prohibited - risk of damage!
