Anti-theft protection
Electronic engine 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. This electronic engine immobiliser locks the engine management system a few minutes after the ignition is switched off and prevents starting of the engine by anyone who does not have the key. In the event of a malfunction, you are informed by a message in the instrument panel screen. In this case, your vehicle does not start; contact a CITROËN dealer as soon as possible.
Ignition on without
starting
With the electronic key in the reader or the Keyless Entry and Starting key inside the vehicle, pressing the "START/STOP" button, with no action on the pedals , allows the ignition to be switched on.
Press the "START/STOP" button, the instrument panel comes on but the engine does not start. Press the button again to switch off the ignition and so allow the vehicle to be locked.
With the ignition on, the system goes into energy economy mode when necessary to maintain the state of charge of the battery.

Back-up starting with the Keyless Entry and Starting system
When the electronic key is in the defined zone and your vehicle does not start after pressing the "START/STOP" button: Insert the electronic key in the reader. Press the brake pedal. Press the "START/STOP" button. The hybrid system is active.
Back-up switch-off
In the event of an emergency only, the engine can be switched of without any conditions. To
do this, press and hold the "START/STOP" button for about 3 seconds. In this case the steering column locks as soon as the vehicle stops.
Electronic key not recognised by the "Keyless Entry and Starting" system
If the electronic key is no longer in the defined zone when driving or when you (later) request switching off of the hybrid system, a message appears in the instrument panel.
Press and hold the "START/STOP" button for about 3 seconds if you want to force
switching off of the hybrid system (note that restarting will not be possible without the electronic key in the defined zone).
The electronic key must always remain inside the vehicle when in use.

51Hybrid system
This system does not work continuously, but adapts the force of the fan cooling to the requirements of the battery. Its operation can be heard at the rear, even if the vehicle is stopped after a run. If the air intake is blocked, the battery may overheat, damaging the battery and causing a loss of per formance of the hybrid system.
Fan cooling of the high voltage battery
For the best use of the high voltage battery, please follow these recommendations: - do not obstruct the air intake with loose articles, otherwise, the battery may overheat, causing a loss of per formance of the hybrid system - do not spill fluids, as this may cause damage to the battery.
The high voltage battery has an air cooling system, comprising an air intake (located on the side of the left hand rear seat) and a fan (located behind the left hand boot trim panel).

The high voltage battery must not in any circumstances be charged from an external source and must only be handled by a workshop technician. There is the risk of serious burns, as well as electric arcs that could cause serious injury or even death. A used Ni-MH (Nickel Metal Hydride) type high voltage battery must be removed in an appropriate manner by a repair workshop, so that its recycling presents no risk to the environment.
High voltage
The voltage used for the operation of the electric motor is in the range 150 to 270 Volts. Be sure to take account of the warning labels fitted to the vehicle. Take great care regarding the high voltage and high temperatures of components carrying the current.
Emergency cut-off
In the event of an accident, a cut-off system blocks the high voltage current and cuts off the fuel pump; your vehicle can no longer be started.
To restart the hybrid system, contact a CITROËN dealer.
High voltage cables are routed under the vehicle (sills); take care not to damage them when the vehicle is used for off-road activity (such as covering rough ground).
Before doing any work on the vehicle, switch off the ignition ( Ready lamp off).
Battery precautions
High voltage cables
Take care to position lifting equipment ( jack, hoist, ...) at the locations provided to avoid damaging the cables.
Never touch, dismantle, remove or replace the high voltage parts, orange cables or connectors, even in the event of an accident.

67Monitoring
Warning / indicator lampStateCauseAction / Observations
Dynamic stability control (DSC/ASR)
flashing. The DSC/ASR regulation is operating. The system optimises traction and improves the directional stability of the vehicle in the event of loss of grip or trajectory.
fixed. The DSC/ASR system has a fault. Have it checked by a CITROËN dealer or a qualified workshop.
Engine autodiagnosis system
flashing. The engine management system has a fault. Risk of destruction of the catalytic converter. Have it checked by a CITROËN dealer or a qualified workshop.
fixed. The emission control system has a fault. The warning lamp should go off when the engine is started. If it does not go off, contact a CITROËN dealer or qualified
workshop without delay.
Anti-lock Braking System (ABS)
fixed. The anti-lock braking system has a fault. The vehicle retains conventional braking. Drive carefully at reduced speed and contact a CITROËN dealer or a qualified workshop without d e l ay.
Braking fixed. The braking system fluid level has dropped significantly. You must stop as soon as it is safe to do so. Top up with brake fluid listed by CITROËN. If the problem persists, have the system checked by a CITROËN dealer or a qualified workshop.
+ fixed, associated with the ABS warning lamp.
The electronic brake force distribution (EBFD) system has a fault. You must stop as soon as it is safe to do so. Have it checked by a CITROËN dealer or a qualified workshop.

Service overdue
Every time the ignition is switched on, an overdue service is immediately signaled by flashing of the spanner and the fixed illumination of the Service warning lamp.
The distance remaining may be weighted by the time factor, depending on the driving conditions. Therefore, the spanner may also come on if you have exceeded the period since the last service, indicated in the maintenance and warranty guide .
Following this operation, if you wish to disconnect the battery, lock the vehicle and wait at least five minutes for the zero reset to be taken into account.
5 seconds after the ignition is switched on, the distance recorder resumes its normal operation. The spanner remains on .
Service indicator zero reset
After each service, the service indicator must be reset to zero. The procedure for resetting to zero is as follows: switch off the ignition, press and hold the trip distance recorder
zero reset button, switch on the ignition; the distance recorder display begins a countdown, when the display indicates "=0" , release the button; the spanner disappears.
Retrieving the service information
You can access the service information at any time. Press the trip distance recorder zero reset button. The service information is displayed for a few seconds, then disappears.
