four wheel drive CITROEN C4 PICASSO 2022 Owners Manual

105
In emergency braking, press the brake
pedal hard and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or
a


qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a problem with grip or trajectory.
Deactivation of the ASR
In exceptional conditions (starting a vehicle
w hich is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip. F

I
n the Driving
menu, select the " Driving
functions " tab, then " Traction control".
Deactivation is confirmed by the display of
a

message.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivation of the ASR
The system is reactivated automatically every
time the ignition is switched back on or from
31
mph (50 km/h).
Below 31
mph (50 km/h), you can reactivate it
manually:
F

I
n the Driving menu, select the " Driving
functions " tab, then " Traction control".
Operating fault
The illumination of this warning
lamp, accompanied by an audible
signal and a
message, indicates that
there is a
fault with these systems. ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
This is indicated by flashing of this
warning lamp in the instrument
panel. Reactivate the system when grip conditions
allow.
Contact a
CITROËN dealer or a qualified
workshop to have the systems checked.

Safety

142
Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine may
stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
the risk of injury related to an automatic
change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a


long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
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 when the tyres
are "cold" (vehicle stopped for 1 hour or
after a
journey of less than 6 miles (10 km)
at moderate speeds).
Other wise, add 0.3
bar (30 kPa) to the
values indicated on the label.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp,
an audible signal and, depending
on equipment, the display of
a


message.

educe speed immediately, avoid excessive
steering movements and sudden braking.

S

top the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a
visual
check. F

I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.

F
I
n case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a
warning if a pressure is
incorrect at the time of reinitialisation. Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Reinitialisation of the system is done on the
touch screen, with the ignition on and the
vehicle stationary.

n the Driving
menu, select the " Driving
functions " tab, then " Under-inflation
initialisation ".

C
onfirm the instruction by pressing "
Ye s",
an audible signal and a message confirm
the reinitialisation.
The new pressure parameters saved are
treated as reference values by the system.
Malfunction
F If you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold. In this case, under-inflation monitoring of the
tyres is no longer provided.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the Ser vice warning lamp
indicates a
fault with the system.
A message appears, accompanied by an
audible signal.

Towing another vehicle
General recommendations
Obser ve the legislation in force in your
c o u nt r y.
Ensure that the weight of the towing
vehicle is greater than that of the towed
vehicle.
The driver must remain at the wheel of
the towed vehicle and must have a
valid
driving licence.
When towing a
vehicle with all four wheels
on the ground, always use an approved
towbar: rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine
off, there is no longer braking and steering
assistance.
In the following cases, you must always
call on a
professional recovery ser vice:
