2021 CITROEN C4 CACTUS ECO mode

74
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 obser vation of
the manufacturer's recommendations
regarding as much the wheels (tyres and
rims), braking and electronic components
as 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.Grip control
Special patented traction control system which
improves traction on snow, mud and sand.
This system, the operation of which has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered when using a passenger car).
Associated with 205/50 R17 all-season M+S
(Mud and Snow) tyres, this system offers a
compromise between safety, grip and traction.
These tyres are efficient in winter and summer
conditions.
The accelerator pedal should be pressed
sufficiently to allow the system to use the power
of the engine. Operation at high engine speeds
is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on to confirm your choice.
A specific and additional display appears
temporarily in the touch screen to confirm the
selection made with the knob.
Standard (ESC)
This mode is calibrated for a low level of wheel
spin, based on the different levels of grip
normally encountered on the road.F

P
lace the knob in this position.
Every time the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions
of grip encountered for each of the two front
wheels on moving off.
(mode active up to 50 mph (80 km/h)) F

P
lace the knob in this position.
Safety

75
All road (mud, damp grass,
etc.)
This mode, when moving off, allows
considerable spin on the wheel with the least
grip to optimise clearing of the mud and regain
grip. At the same time, the wheel with the most
grip is controlled in such a way as to pass as
much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50 km/h))F

P
lace the knob in this position.
Sand
This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move for ward and limit the risks of getting stuck
in the sand.
(mode active up to 75 mph (120 km/h))F

P
lace the knob in this position.
Do not use the other modes on sand as
the vehicle may become stuck. You can deactivate the ASR
and DSC systems by turning
the knob to the "
OFF" position.
The ASR and DSC systems will no longer
have an effect on engine operation or
the brakes in the event of an involuntary
change of trajectory.
These systems are reactivated
automatically from 31 mph (50 km/h) or
every time the ignition is switched on.
Driving recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road
driving such as:
- c rossing and driving on terrain which
could damage the underbody or strip
away components (fuel pipe, fuel
cooler, etc.) due to obstacles or stones
in particular,
-

d
riving on terrain with steep gradients
and poor grip,
-

c
rossing a stream.
Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of
the seat belt on the occupant's chest, thus
improving their protection.

Starting/Switching off the
engine with the key
Ignition switch
Ignition on position (2)
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reser ve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preser ve the remaining
battery charge.Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch
and could cause a malfunction.
Switching off the engine leads to a loss of
braking assistance.

message disappears.
When driving on flooded roads or when
crossing a ford, proceed at walking pace.
Malfunction
When the ignition is on, the lighting
of this warning lamp, associated
with an audible signal and an alert
message on the screen, indicates a
gearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd gear. You may feel a
substantial jolt when changing from P to R and
from N to R. This will not cause any damage to
the gearbox. There is a risk of damage to the gearbox:
-

i
f you press the accelerator and brake
pedals at the same time,
-
i
f you force the movement of the
selector from position P to another
position when the battery is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake.
If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.
Do not exceed 62 mph (100 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.

your foot on the brake pedal, press control N ,
then R .
Stopping the vehicle
Before switching off the engine, you can:
-
p ress control N to be in neutral,
or
-

l
eave the vehicle in gear; in this case the
vehicle cannot be moved.
For all parking situations, you must apply
the parking brake to immobilise the
vehicle.
When immobilising the vehicle with the
engine running, you must select neutral N .Before doing anything under the bonnet,
ensure that control N has been pressed
and that the parking brake is applied.
Operating fault
With the ignition on, illumination of
this warning lamp, accompanied by
an audible signal and a message,
indicates a gearbox fault.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears. The system is only active on vehicles fitted
with a manual gearbox.
On certain BlueHDi Diesel versions with
manual gearbox, in certain driving conditions
the system may suggest changing into neutral
so that the engine can go into standby (STOP
mode with Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be disabled.
The information appears in the instrument
panel in the form of an arrow.
