2021 CITROEN C4 CACTUS low beam

61
Lighting control stalk
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
If one or more lamps fails, a message
asks you to check the lamp or lamps
concerned.
Travelling abroad
If planning to use your vehicle in a country
that drives on the other side of the road,
the headlamp dipped beams must be
adjusted to avoid dazzling oncoming
drivers. Contact a CITROËN dealer or a
qualified workshop.

This is confirmed by an audible signal and
illumination of the corresponding direction
indicator lamp in the instrument panel.
To switch off the parking lamps, return the
lighting control stalk to the central position.

makes use of the beam from a front foglamp
to illuminate the inside of a bend, when the
main or dipped beam headlamps are on and
the vehicle speed is below 25 mph (40 km/h)
(urban driving, winding road, intersections,
parking manoeuvres, etc.). Without cornering lighting

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 620 miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing device is used. If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised to enable
vehicle start.
This electronic engine immobiliser locks
the engine management system a moment
after the ignition is switched off and prevents
unauthorised engine starting.
In the event of a fault, you are
informed by the illumination of this
warning lamp, an audible signal and
a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer or a qualified workshop as
soon as possible.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

Driving

In temperate conditions, do not let the
engine idle to warm up but move off
straight away and drive at moderate
speed.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. Danger of poisoning and death!
In very extreme wintry conditions
(temperature below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must
be left running for four minutes before
starting the vehicle.

applied, particularly on sloping ground.
Never switch off the ignition before the
vehicle is at a complete stop. With the
engine off, the braking and steering
assistance systems are also cut off: risk of
loss of control of the vehicle.
When you leave the vehicle, keep the key
with you and lock the vehicle.
Energy economy mode
After switching off the engine (position 1 –
Stop ), for a maximum of 30 minutes you
can still use functions such as the audio and
telematics system, the wipers, dipped beam
headlamps, courtesy lamps, etc.
