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, never leave children alone in the vehicle, even for a very short time.
In all cases, take the remote control or electronic key (if Keyless Entry and Starting) with you when leaving the vehicle.
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.

Driving recommendations
Observe the driving regulations and remain 
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your 
hands on the wheel so that you are ready to 
react at any time to any eventuality.
On a long journey, a break every two hours is 
strongly recommended.
In difficult weather, drive smoothly, anticipate 
the need to brake and increase the distance 
from other vehicles.Never drive with the parking brake 
applied - Risk of overheating and 
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle 
is very hot, even several minutes after 
switching off the engine, do not park 
or run the engine over areas where 
inflammable substances and materials 
are present: grass, leaves, etc.
Never leave a vehicle unsupervised 
with the engine running. If you have 
to leave your vehicle with the engine 
running, apply the parking brake 
and put the gearbox into neutral or 
position
 
N or P, depending on the type 
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded 
roads, as this could cause serious damage 
to the engine or gearbox, as well as to the 
electrical systems of your vehicle.
Important!If you are obliged to drive through water:
-
 
c
 heck that the depth of water does not 
exceed 25 cm, taking account of waves 
that might be generated by other users,
-
 
d
 eactivate the Stop & Start system,
-
 
d
 rive as slowly as possible without 
stalling. In all cases, do not exceed 6 mph 
(10
  km/h),
-
 
d
 o not stop and do not switch off the 
engine.
On leaving the flooded road, as soon as 
circumstances allow, make several light brake 
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact 
a CITROËN dealer or a qualified workshop.
Never drive in a depth of water which 
could cover the axles, the wheel shafts 
and which could enter the exhaust.
