check engine CITROEN C4 SPACETOURER 2022 Owner's Manual

156
The adaptive cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
-
i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle and
the vehicle in front.
The regulation range is limited to a maximum
d ifference of 19 mph (30 km/h) between the
cruise speed setting and the speed of the
vehicle in front. Above this, the system goes into
pause if the safety distance becomes too short.
Poor weather conditions (very heavy
rain, accumulation of snow in front of the
radar) may hinder the operation of the
system, with the display of the operating
fault message "SYSTEM INACTIVE:
Reduced visibility". The function remains
unavailable until the message disappears.
Since the radar detection range is relatively
narrow, it is possible that the system cannot
detect:
-

v
ehicles of reduced width, such as
motorcycles, for example, -

v
ehicles not running in the middle of the
lane,
When the adaptive cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. The message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the function be
reactivated by pressing button 2

or 3,

which will make the current speed of your
vehicle the new cruise speed setting,
rather than by pressing button 4 (on /
pause) which reactivates the cruise control
using the old cruise speed setting, which
may be very different from the current
speed of your vehicle.
Operating limits
- if the system does not slow the vehicle enough to continue to maintain a safe
distance, for example when descending
a
steep hill.
-
v

ehicles entering a

corner,
-

v
ehicles changing lane at the last moment.
The cruise control does not take account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite direction.
Malfunction
In the event of a malfunction of the adaptive
c ruise control system, you are warned by an
audible signal and the display of the message
"Driving aid functions fault".
Have the system checked by a
CITROËN
dealer or a
qualified workshop.

ollowing impact to the windscreen close to
the detection camera. The system is automatically deactivated
after the use of the "space-saver" type
spare wheel is detected, or if a
fault with
the lateral brake lamps is detected.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.
After an impact, the function automatically
stops operating. Contact a
CITROËN
dealer or a
qualified workshop to have the
system checked.
If the front bumper is to be repainted or
retouched, contact a
CITROËN dealer
or a
qualified workshop. Certain types of
paint could inter fere with the operation of
the radar.
Collision Risk Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or
a
pedestrian present in your traffic lane.
The current threshold can only be
modified via the touch screen's
Driving menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel.
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.

Park Assist
This system provides active assistance with
parking: it detects a
parking space then
operates the steering system to park in this
space.
With a
manual gearbox , the driver manages
the accelerator, brakes, gears and clutch.
With an automatic gearbox (EAT6/EAT8) , the
driver manages the accelerator, brakes and
gears.
During phases of entry into and exit from
a
parking space, the system provides visual
and audible information to the driver in order
to make the manoeuvres safe. It may be
necessary to move for wards and backwards
more than once. The driver can take control at any time by
gripping the steering wheel.
This manoeuvring assistance system
cannot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in their
blind spots.
The Park Assist system cannot work with
the engine off.
A. Parallel parking.
B. Exit from a


parallel parking space.
C. Bay parking.
The Park Assist system provides assistance for
the following manoeuvres:
6
Driving

182
During manoeuvring phases, the steering
wheel per forms rapid turns: do not hold
the steering wheel, do not put your hands
between the spokes of the steering wheel.
Watch out for any object that could block
the manoeuvre (loose clothing, scar ves,
ties, etc.) - injury risk!
When the Park Assist is active, it prevents
the Stop & Start going into STOP mode.
In STOP mode, activating Park Assist
restarts the engine.
The Park Assist system takes control
of the assistance for a maximum of
4
manoeuvre cycles. The function is
deactivated after these 4
cycles. If you
think that your vehicle is not positioned
correctly, you should then take control of
the steering to carry out the manoeuvre. The sequence of manoeuvres and the
driving instructions are displayed in the
instrument panel.
You should always check the surroundings
of your vehicle before starting
a


manoeuvre.The parking sensors function is
not available during parking space
measurement. It intervenes later when
manoeuvring to warn you that your vehicle
is approaching an obstacle: the audible
signal becomes continuous when the
obstacle is less than thirty centimetres
away.
If you have deactivated the parking
sensors, they are automatically
reactivated during assisted parking
manoeuvres.
Activation of Park Assist deactivates the
Blind Spot Detection.

Misfuel prevention (Diesel)
(Depending on the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
It remains possible to use a fuel can to fill
t he tank.
In order to ensure a
good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device and pour slowly. Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.
When a petrol filler nozzle is introduced into
the fuel filler neck of a Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation tips
F If you have to fit the chains during a journey,
stop the vehicle on a flat sur face on the side
of the road.
F

A
pply the parking brake and position any
wheel chocks under the wheels to prevent
movement of your vehicle.
F

F

provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 31
mph
(50


km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a
level and dry sur face.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging your vehicle's tyres and the
road sur face. If your vehicle is fitted with
alloy wheels, check that no part of the
chain or its fixings is in contact with the
wheel rim.

Engine oil change
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3,000
miles (5,000 km).

Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up. To avoid the risk of scalding when you need to
top up in an emergency, wrap a
cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Screenwash/headlamp
wash level low
In the case of vehicles fitted with
headlamp washers, when the fluid
reser voir low level is reached this
warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a


message.
The warning lamp comes on when the ignition
is switched on, or every time the stalk is
operated, until the reser voir is refilled.
The next time you stop, have the screenwash/
headlamp wash reser voir topped up.
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a
message that
the particle filter additive level is
too low.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and, in particular, topping up the tank,
refer to the corresponding section.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.

Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a CITROËN
dealer or a
qualified workshop.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release terminals)
and that the connections are clean.
For more information and the precautions
to take before starting work on the 12 V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a
12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a
CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary .
Passenger compartment
filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary.
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is signalled by the temporary
illumination of this warning lamp
accompanied by a message warning
of the risk of the filter clogging up.
Traffic conditions permitting, regenerate
the filter by driving at a
speed of at least
37

mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a

low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
On a

new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
