coolant
temperature gauge
With the engine running:
- i n zone A , the temperature is correct,
-

i
n zone B, the temperature is too high; the
central STOP warning lamp comes on,
accompanied by an audible signal and a
message in the instrument panel screen.
You MUST stop as soon as it is safe to do so.
Wait a few minutes before switching off the
engine.
Contact a CITROËN dealer or a qualified
workshop. After driving for a few minutes, the temperature
and pressure in the cooling system increase.
To top up the level:

on the reservoir).

For maximum cooling or heating of the
passenger compartment, it is possible
to exceed the minimum value 14 or the
maximum value 28.

until
"LO" is displayed or to the
right until "HI" is displayed.
See the "Front demisting -
defrosting" section.
2-3. driver's-passenger's side
settings
The driver and front passenger can
each adjust the temperature to their
requirements.
F

T

urn control 2 or 3 to the left or to the right
respectively to decrease or increase this
value.
A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
You are advised to avoid a left / right setting
difference of more than 3.
Manual operation
If you wish, you can make a different choice
from that offered by the system by changing a
setting. The "AUTO" indicator lamps go off; the
other functions, except the air conditioning, will
still be controlled automatically.
F

P
ressing the "AUTO" button returns the
system to completely automatic operation.
With Stop & Start, when demisting has
been activated, the STOP mode is not
available.
The value indicated on the display corresponds
to a level of comfort and not to a temperature in
degrees Celsius or Fahrenheit.

driving advice
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 on a long
mountain type of descent, 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.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Opening the bonnet
Opening
F From inside: pull the release lever, located
on the left below the dashboard, towards
you.
Before doing anything under the
bonnet, switch off the Stop & Start
system to avoid any risk of injury
resulting from an automatic change to
START mode.
closing
F Lower the bonnet and release it at the end
of its travel.
F

C
heck that it is latched correctly.
F

F
rom the outside
: lift the safety catch and
raise the bonnet.
A bonnet strut opens the bonnet and holds it
open.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, ...) be limited. 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.

DS5_en_Chap09_verifications_ed01-2015
Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms). To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes.
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.checking using the dipstick
Refer to the "Petrol engine" or "Diesel engine"
section for the location of the dipstick in the
engine compartment of your vehicle.

efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between the marks A
and B . A = MA X
B = MIN
If you find that the level is above the A mark or
below the B mark, do not star t the engine .
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top up the engine oil.

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.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.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades.
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 an ethyl alcohol
or methanol base fluid is recommended.
Screenwash / headlamp

To check the level or top up the fluid on vehicle
fitted with headlamp washers, immobilise the
vehicle and switch of the engine.

Removable screen which prevents the accumulation of snow at the radiator cooling fan.
Very cold climate screen *
Before fitting or removing the screen, ensure that the engine is off and the cooling fan has stopped. It is recommended that the screen be fitted and removed by a CITROËN dealer or a qualified workshop.
Do not forget to remove the very cold climate screen: - when the ambient temperature exceeds 10° C (for example: in summer, ...), - when towing, - at speeds above 75 mph (120 km/h).
Fitting
 Offer up the screen to the front of the front b u m p e r.  Press on the screen to engage its fixing clips.
Removal
 Use a screwdriver as a lever to unclip each retaining clip in turn.
