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

i
n zone B , the temperature is too high; this
warning lamp and the central STOP warning
lamp come on in the instrument panel,
accompanied by the display of a message
and an audible signal.
You must stop as soon as it is safe to do so.
Wait a few minutes before switching off the
engine.
After first switching off the ignition, open
the bonnet cautiously and check the
coolant level. For more information on Checking levels
,
refer to the corresponding section.

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 towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
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. 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.
F

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 600
miles (1,000 kilometres).
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
If the system fails, as reported by a message,
the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

The location of the interior bonnet release
lever prevents opening of the bonnet when
the left-hand front door is shut. When the engine is hot, handle the
exterior safety catch and the stay with
care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
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.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, etc.) be limited. Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid the risk of injury related to an
automatic change to START mode.

If you find that the level is above the mark A or
below the mark B , do not star t the engine.

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.
Oil grade
Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
Topping up the engine oil level
F Unscrew the oil filler cap to access the filler opening.
F

fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not
valid during the 30
minutes after topping
up.
Engine oil change
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fluid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face with
the engine cool.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.

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 the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up the coolant.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.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
A low coolant level presents a risk of serious
damage to your engine.
Top up the fluid when necessary.Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel fuel additive level
(Diesel with particle filter)
The additive tank minimum level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue
® and the SCR
system, and, in particular, topping it up, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release
terminals) and that the connections
are clean.
