Driving
6As soon as the speed of the vehicle drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).
Driver Attention Warning
Depending on version, the Coffee Break Alert
system may be combined with the Driver
Attention Warning system.


The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by
the message "Caution!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Driving at
risk: Take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

lane markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

close to the vehicle ahead (lane markings
not detected);
–


roads that are narrow
, winding, etc.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system detects and signals the proximity of
obstacles (e.g.
pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.

Practical information
7Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 15 litres.
Its capacity allows a driving range of
approximately 4,000
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400

km) before the tank is
empty and the vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 685
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–

Use
only AdBlue
® fluid that meets the ISO
22241 standard.
–

Never

transfer AdBlue
® to another container
as it would lose its purity.
–

Never

dilute AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN dealer
or a qualified workshop, as well as service

Practical information
7Stain removal
Do not rub the stain or it may spread or
you may cause the substance to
penetrate the surface.
Act quickly by reducing the stain from its edges inwards.
Remove as much substance or solids as
possible using a spoon or spatula, and
remove
as much liquid as possible using
absorbent paper.
Product/Procedure to use depending
on the type of stain:
–

Grease, oil and ink: clean with a pH-neutral
detergent.
–


V

omit: clean with sparkling mineral water.
–

Blood: spread flour over the stain and allow
to dry; remove with a slightly damp cloth.
–


Mud: allow to dry and then remove with a
slightly damp cloth.
–


Cake, chocolate, ice cream: clean with
lukewarm water

.
–

Sugary and/or alcoholic drinks: clean with
lukewarm water

, or lemon juice if the stain is
persistent.
–

Hair gel, coffee, tomato sauce, vinegar:
clean with lukewarm water and lemon juice.
For solid substances, then use a soft brush or
vacuum cleaner

.
For liquid substances, then use a damp
microfibre cloth and then dry with another
cloth.
Leather
Leather is a natural product. Appropriate regular
care is essential for its durability.
It must be protected and nourished using a
specific leather product, to keep it supple and
preserve its original appearance.
Do not clean leather using unsuitable
cleaning agents such as solvents,
detergents, petrol or pure alcohol.
When cleaning items partly made from
leather, take care not to damage the other
materials with the specific leather product.
Before cleaning greasy stains or liquids,
quickly mop up any surplus.
Before cleaning, wipe off any residues liable
to scuff the leather, using a cloth that has
been dampened with demineralised water
and thoroughly wrung out.
Clean leather using a soft cloth moistened
with soapy water or a pH-neutral product.
Dry with a soft, dry cloth.
