Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the
bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof
bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in
the door aperture, driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter...) and
observe the schedule of operations recommended by the manufacturer.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Service indicator
System which informs the driver when the
next service is due in accordance with the
manufacturer's servicing schedule.
The point at which the next service is due is
calculated from the last service indicator zero
reset.
It is determined by two parameters:
-
t
he distance travelled (in miles (km)),
-

t
he time elapsed since the last service
(in months).
The distance remaining to be travelled may be
weighted by the time factor, depending on the
use made of the vehicle.
Example: the screen indicates that 7300 miles
(kilometres) remain before the next service
is due.Service overdue
Example: the screen indicates that the service
is overdue. This service must be carried out by
a CITROËN dealer or a qualified workshop.
Operation
The symbol "-- " remains displayed until
the first service of a new vehicle has
been carried out. Each time the ignition is switched on, the
"ROUTINE MAINTENANCE REQUIRED"

symbol is displayed for a few seconds to indicate
that the service must be carried out without delay.
When the ignition is switched on, you must press
the
INFO button several times in succession
until the service indicator is displayed. The
distance recorder display line indicates the
number of miles or kilometres remaining and
the time elapsed line indicates the number of
months remaining before the next ser vice is due.

Lost electronic key
Visit a CITROËN dealer with the vehicle's registration document and your personal identification documents and if possible the key code label.
The CITROËN dealer will be able to retrieve the key code and the transponder code required to order a new key.
Electronic key
The electronic key is a sensitive system; do not operate it while it is in your pocket as there is a possibility that it may unlock the vehicle, without
you being aware of it.
Do not repeatedly press the buttons of your electronic key out of range and out of sight of your vehicle. You run the risk of stopping it from
working and the remote control would have to be reinitialised.
The electronic key cannot operate as a remote control when it is in the reader or even when the ignition is switched on.
Locking the vehicle
Driving with the doors locked may make access to the passenger compartment by the emergency services more difficult in an emergency.
As a safety precaution (with children on board), take the Keyless Entry and Starting electronic key when you leave the vehicle, even for a short
time.
Electrical interference
The Keyless Entry and Starting electronic key may not operate if close to certain electronic devices: telephone, laptop computer, strong
magnetic fields, ...
Anti-theft protection
Do not make any modifications to the electronic engine immobiliser system; this could cause malfunctions.
Don't forget to turn the steering to engage the steering lock.
When purchasing a second-hand vehicle
Have all of the keys in your possession paired by a CITROËN dealer, to ensure that only your keys allow your vehicle to be unlocked and
started.
