2015.5 Citroen DS4 RHD coolant

Warning lamps
When the engine is running or the vehicle is being
driven, the illumination of one of the following warning
lamps indicates a malfunction which requires action
on the part of the driver.
The warning comes on in the instrument panel or
appears in the type 2 instrument panel central screen.If your vehicle has a screen, a warning lamp coming on is always accompanied by the
display of an additional message, to assist you in identifying the problem.
If you encounter any problems, do not hesitate to contact a CITROËN dealer or a qualified
workshop.
Warning /indicator lampis on Cause Action/Observations
STOP fixed, alone or
associated with
another warning lamp,
accompanied by an
audible signal and a
message in the screen. Illumination of this warning lamp is
associated with a serious fault with
the braking system, power steering,
engine lubrication system or cooling
system.
Stop as soon as it is safe to do so as there is a risk that
the engine will cut out while driving.
Park, switch off the ignition and contact a CITROËN
dealer or a qualified workshop.
Maximum coolant
temperature fixed.
The temperature of the cooling system
is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down before topping
up the level, if necessary.
If the problem persists, contact a CITROËN dealer or
qualified workshop.
Engine oil
pressure fixed.
There is a fault with the engine
lubrication system. You must stop as soon it is safe to do so.
Park, switch off the ignition and contact a CITROËN
dealer or a qualified workshop.

When towing
distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding
it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side 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 a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
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 hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
For more information on weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.
Screenwash / headlamp
wash fluid 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.
When the engine is warm, 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.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top up the level.

Specification of the fluid
To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of a fluid
with an ethyl alcohol or methanol base is
recommended.
