Indicators
Coolant temperature indicator




With the engine running:
– In zone A, the temperature is correct.
– In zone B, the temperature is too high.
The associated warning lamp and the
STOP
warning lamp light up in red on the
instrument panel, accompanied by the display of
a message and an audible signal.
You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully open the bonnet and check the coolant
level.
For more information on Checking
levels, refer to the corresponding
section.
Service indicator
The servicing information is expressed in terms
of distance (miles or kilometres) and time
(months or days).
The alert is given at whichever of these two
terms is reached first.
The servicing information is displayed in the
instrument panel. Depending on the version of
the vehicle:
–

The distance recorder display line indicates
the distance remaining before the next service
is due, or the distance travelled since it was due
preceded by the "-" sign.
– An alert message indicates the distance
remaining, as well as the period before the next
service is due or how long it is overdue.
The value indicated is calculated according to the distance covered and
the time elapsed since the last service.
The alert may also be triggered close to a
due date.
Service spannerOn temporarily when the ignition is
switched on.
Between 620 and 1,860 miles (1,000 and 3,000

Have your vehicle serviced very soon.
Service spanner flashingFlashing then fixed, when the
ignition is switched on.
(With

BlueHDi Diesel engines, associated with
the Service warning lamp.)
The servicing interval has been exceeded.
Have your vehicle serviced as soon as possible.
Resetting the service indicator
The service indicator must be reset after each
service.
►

Switch the ignition off.



CHECK

► Press and hold this button.
► Switch on the ignition; the distance recorder
display begins a countdown.
► Release the button when =0 is displayed; the
spanner disappears.
If you have to disconnect the battery
following this operation, lock the vehicle
and wait at least 5 minutes for the reset to be
registered.
Reminder of the servicing information
You can access the servicing information at any
time.
► Press the trip distance recorder reset button.
The servicing information is displayed for a few
seconds, then disappears.
Engine oil level indicator
(Depending on version)
On versions fitted with an electric gauge, the
engine oil level status is displayed on the
instrument panel for a few seconds when

Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave the electronic key in the
vehicle, even when you are close to it.

Practical information
7► Pull the interior release lever, located at the
bottom of the door frame, towards you.


► Tilt the safety catch to the left and raise the
bonnet.


► Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the
support slot.
►

Clip the stay in its housing.
►


Lower the bonnet and release it near the end
of its travel.
►


Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

Practical information
7supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►
Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap 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 to the required level.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Visit a CITROËN dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
