Driving
6Driving 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 to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
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 leave a 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 internal combustion engine or electric motor,
the gearbox and the electrical systems of the
vehicle.


If you are obliged to drive on a flooded road:
► 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 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.
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).

98
Driving
automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– position 1 (Stop): inserting and removing the
key, steering column locked.
–
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating, engine
running,
–

charge level or outside temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.

111
Driving
6partially recharge the traction battery, without
affecting the charge level indicator.
Progressive Hydraulic
Cushions
This suspension system with progressive hydraulic cushions improves driving comfort by
filtering out the imperfections and demands of
the road surface.
Each shock absorber is equipped with a
hydraulic compression stop (at the base) and a
hydraulic rebound stop (at the top).
Depending on the intensity of the shock to be
absorbed, these stops provide the vehicle with a
greater freedom of movement or gradually slow
down the amount of movement in order to avoid
any sudden jolts at the end of travel.
Unlike conventional suspension which absorbs
the energy but then partially returns some of it,
this active suspension absorbs and dissipates
this energy, without producing any rebound.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using one of the
following controls, depending on version:




1. Pressing the control activates Eco mode. The
indicator lamp comes on.
2. Pressing the control activates Sport mode.
The indicator lamp comes on.
3. Pressing the control displays the modes on
the instrument panel.
The selected mode is activated immediately.
With petrol / Diesel engines
Each time the ignition is switched on, Normal
mode is selected by default.
Eco
Reduces energy consumption by restricting the
performance of the heating and air conditioning
systems, although it does not deactivate them.
Normal
Restores the vehicle’s original settings.
Sport
Enables more dynamic driving with action on the
power steering, accelerator and gear changes
(with an automatic gearbox).
Depending on version, with an EAT8
gearbox and the selector in position D
(except Sport mode), fully releasing the
accelerator pedal allows free-wheeling which
can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).
With rechargeable hybrid
engine
Each time the ignition is switched on, Electric
mode is selected by default.
Electric
Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135
km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument
panel. The vehicle automatically changes to
Hybrid mode.
If a blue LED comes on under the interior rear
view mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode.
