one A, the temperature is correct,
-
in z

one 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 exceed the minimum value 14 or the
maximum value 28.

The driver and front passenger can
each adjust the temperature to their
requirements.
F

rn 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
Pr

essing 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.

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

Air density decreases with altitude, thus
reducing engine per formance. Above

be reduced by 10

altitude.
Side wind
F Take into account the increased sensitivity
t o 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
To l

ower 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
If t

he 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
v ehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling
o n 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.

Starting using another
battery
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery
b o o s t e r.
First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, ...).
Ensure that the jump lead cables do
not pass close to moving parts of the
engine (cooling fan, belts, ...).

the engine is running.F

vehicle and let the engine run.
If t

switch off the ignition and wait a few
moments before trying again.
When your vehicle's battery is discharged, the
engine can be started using a slave battery
(external or on another vehicle) and jump lead
cables or a battery booster.

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.

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

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
d ipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.

non-fluffy cloth.
F
Re

fit 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 .
-
If t

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

he 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

fitted with headlamp washers, immobilise the
vehicle and switch of the engine.
