2015 Citroen NEMO check engine

39ELECTRONIC IMMOBILISER
All of the keys contain an electronic
immobiliser device.
This device locks the engine supply system.
It is activated automatically when the key is
removed from the ignition.
After the ignition is switched on, a dialogue
is established between the key and the
electronic immobiliser system.This warning lamp is switched off
after the ignition is switched on
and the key has been recognised,
the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.
Good practice
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms…), may interfere with the
operation of the remote control temporarily.
When purchasing a second-hand vehicle:
-

ensure that you are given the confidential

card,
-

have the keys memorised by a CITROËN

dealer to ensure that the keys in your
possession are the only ones which can
start the vehicle.
CONFIDENTIAL CARD
This is given to you on delivery of your
vehicle with the duplicate keys.
It contains the identification code necessary
for any work carried out by a CITROËN
dealer on the electronic immobiliser system.
This code is hidden by a film, which should
be removed only if necessary.
k

eep your card in a safe place, never inside
the vehicle.
When undertaking a long trip or journey,
however, it is advisable to take it with you
along with your personal papers. Driving with the doors locked may make
access to the passenger compartment
by the emergency services more difficult in an
emergency.
a

s a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.

60HILL START ASSIST
An integral part of the DSC system, it
facilitates starting on a gradient by keeping
your vehicle immobilised temporarily
(approximately 2 seconds), the time it takes
to move your foot from the brake pedal to
the accelerator pedal.
This function is only active when:
-

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

the engine is running,
-


the gradient is steeper than 5 %. Operation
On a slope, with engine running and the


vehicle stationary, the vehicle is held
for a brief moment when you release the
brake pedal:
-

provided you are in first gear or neutral

with a manual gearbox,
-

provided you are in position
A or M with
an electronic gearbox,
On a descending slope, with the vehicle
stationary, the engine running and
reverse gear engaged, the vehicle is held
for a brief moment when you release the
brake pedal.
a

fter 2 seconds, if the vehicle has not
moved off, the system is deactivated
automatically by gradually reducing the
brake pressure. During this phase, the
characteristic sound of brakes being
released will be heard, indicating the
imminent movement of the vehicle.
d
o not leave the vehicle while it is
being held in the hill start assist phase.
If you need to leave the vehicle while the
engine is running, apply the parking brake
manually. Then ensure that the parking
brake warning lamp is on (not flashing) in
the instrument panel.

screen
Have it checked by a CITROËN
dealer or a qualified workshop.
In the event of an operating fault with STOP
mode, it is possible to restart the engine by
depressing the clutch pedal fully and putting
the gear lever into neutral. Before working under the bonnet, you
must switch off the ignition with the
key to avoid any risk of injury resulting from
automatic operation of ST
a
RT mode.
This system requires a specific battery
with a special specification and technology
(reference numbers available from a
CITROËN dealer or a qualified workshop).
Fitting a battery not listed by
CITROËN introduces the risk of malfunction
of the system.
The Stop & Start system makes use
of advanced technology. Specialist
knowledge is needed for any work on the
system, which can only be assured by
CITR
o Ë n dealers.

Emergency braking assistance*
System which, in an emergency, enables
you to reach the optimum braking pressure
more quickly, thus reducing the stopping
distance. The emergency braking assistance
is an integral part of the DSC system.
Activation
It is brought into play by the speed at which
the brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly
without releasing the pressure.
Good practice
This system cannot be deactivated by the
driver.
* Depending on country of sale.
TRAJECTORY CONTROL SYSTEMS
Dynamic stability control

(DSC)
The dynamic stability control system acts on
the brake of one or more wheels and on the
engine to keep the vehicle on the trajectory
required by the driver, within the limits of the
laws of physics.
Activation
This system is activated automatically each
time the vehicle is started and cannot be
deactivated.
It comes into operation in the event of a grip
or trajectory problem.
Illumination of this warning lamp,
accompanied by a message in the
instrument panel screen, indicates
a fault with the system, which is
deactivated automatically.
Have it checked by a CITROËN dealer or a
qualified workshop.
Anti-slip regulation (ASR) and engine
control (MSR)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
Engine control is an integral part of the ASR
system and intervenes when a sudden gear
change is made or of one of the driving
wheels looses grip, by reducing engine
torque to avoid loss of stability of the
vehicle.
Activation
These systems are activated automatically
every time the vehicle is started.
In the event of a problem od adhesion or
trajectory, these systems come into play.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the
a

SR system, so that the
wheels can spin freely and regain grip.
This is indicated by flashing of this
warning lamp in the instrument
panel.

FRONT SEAT BELTS
The front seats are fitted with pre-tensioners
and force limiters.
Fastening
Pull the strap, then insert the tongue into the
buckle.
Check that the seat belt is fastened correctly
by pulling the strap.
The lap belt must be positioned as low as
possible on the pelvis. The chest belt must
pass over the hollow of the shoulder.
Inertia reel seat belts
These are fitted with a device which locks
automatically in the event of a collision or
emergency braking.
Safety in the event of a front impact has
been improved by the introduction of
pretensioning and force limiting seat belts.
Depending on the seriousness of the
impact, the pretensioning system instantly
tightens the seat belt against the body of the
occupant.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt against the body of the occupant in
the event of an accident.
Driver's seat belt not fastened warning
lamp
When the vehicle is started, this
warning lamp comes on if the
driver has not fastened their seat
belt.
REAR SEAT BELTS (COMBI)
The 3-seat bench is fitted with three-point
inertia reel seat belts with force limiter.
The centre seat has a seat belt guide and
inertia reel, integrated with the seat back.
When a seat belt is not in use, you can

store its buckle in the housing provided
in the bench seat cushion.
If the driver's seat belt is unfastened,
the ST
a

RT mode of Stop & Start will
not be invoked. The engine can only be
restarted using the ignition key.

In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this case,
automatic cutting off of the air conditioning
allows the engine power to be saved.If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
ChecksSee the "Levels" section of
chapter 7.
Tyres: check the tyre pressures on the
towing vehicle and the trailer, observing the
recommended pressures.
Brakes: towing increases the braking
distance.
d rive at a moderate speed,
change down early and brake gradually. Side wind: sensitivity to side wind is
increased.
d rive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Distribution of loads
distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of the
engine. The maximum towed load must be
reduced by 10 % for each 1 000 metres of
altitude.
Refer to the "Technical data -
Identification markings" section. Rear parking sensors: the sensors will be
deactivated automatically when an genuine
CITR
o Ë n towbar is used.
Towbar
We recommend the use of genuine
CITR
o Ë n towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle, and that
the fitting of this equipment is entrusted to a
CITROËN dealer or a qualified workshop.

o Ë n

dealer

, it is essential that it is fitted using
the electrical pre-equipment located at
the rear of the vehicle and following the
manufacturer's instructions.
The operation of the rear parking sensors is
deactivated automatically when the trailer
cable connector is inserted in the towbar
socket.
When the trailer cable is removed, the rear
parking sensors are re-activated.
