2014 Citroen DS5 HYBRID4 spare wheel

DS5-HYBRID_EN_CHAP00C_HYBRIDE_ED02-2013
The electronic power super visor - 4automatically manages the operation of the two power units (Diesel and electric) to provide the lowest consumption. An inverter and a transformer are needed to manage the electric power. The inverter acts on the torque of the electric motor, by regulating the current coming from the high voltage battery pack. Its operating range is between 150 and 270 volts. The transformer converts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary systems.
The alternator-starter motor - 5 assures the Stop & Star t function which allows the Diesel engine to be put into standby during stops (traffic lights, a stop, or in a traffic jam, for example) or during phases of running in all-electric mode. The stopping and restarting of the Diesel engine is done in a way that is instantaneous and transparent for the driver. It also provides additional charging of the batteries (4x4 mode for example or under-charged high voltage battery).
The electronic gearbox - 6 provides, in automatic mode, significant savings in fuel consumption compared to a conventional manual gearbox, thanks to its electronic control system. It also offers improved driving pleasure with the possibility at any time of choosing the gear changing mode: automatic or manual, using the paddles located behind the steering wheel.

Tyre under-infl ation detection
System which automatically checks the pressures of the tyres while driving. The system continuously monitors the pressures of the four tyres, as soon as the vehicle is moving. A pressure sensor is located in the valve of a each tyres (except the spare wheel). The system triggers an alert if a drop in pressure is detected in one or more tyres.
This system does not avoid the need to check the tyre pressures regularly (including the spare wheel) and before a long journey. Driving with under-inflated tyres
adversely affects road holding, extends braking distances and causes premature tyre wear, particularly under arduous conditions (vehicle loaded, high speed, long journey).
The tyre pressures for your vehicle can be found on the tyre pressure label (see the "Identification markings" section). The tyre pressures must be checked when the tyres cold (vehicle stopped
for 1 hour or after driving for less then 6 miles (10 km) at moderate speed). Other wise, add 0.3 bar to the values indicated on the label.
Driving with under-inflated tyres increases fuel consumption.
The tyre under-inflation detection system is an aid to driving which does not replace the need for the driver to be vigilant or to drive responsibly.

The alert is maintained until the tyre or tyres concerned is reinflated, repaired or replaced. The spare wheel (space-saver type or a steel rim) does not have a sensor.
The loss of pressure detected does not
always lead to visible deformation of the tyre. Do not rely on just a visual check.
This alert is also displayed when one or more wheels is not fitted with a sensor (for example, a space-saver or steel spare wheel).
The alert is given by the fixed illumination of this warning lamp, accompanied by an audible signal, and depending on equipment, the display of a message.
The flashing and then fixed illumination of the under-inflation warning lamp accompanied by the illumination of the "service" warning lamp indicates a fault with the system.
Under-inflation alert Operating fault
In the event of a problem on one of the tyres, the symbol or the message appears, according to equipment, to identify it.  Reduce speed, avoid sudden steering movements or harsh brake applications.  Stop as soon as it is safe to do so.
Go to a CITROËN dealer or a qualified workshop to have the system checked or, following the repair of a puncture, to have the original wheel, equipped with a sensor, refitted.
In this case, monitoring of the tyre pressures is not assured.
 If you have a compressor (the one in the temporary puncture repair kit for example), check the four tyre pressures when cold. If it is not possible to check the tyre pressures at the time, drive carefully at reduced speed. or  In the event of a puncture, use the temporary puncture repair kit or the spare wheel (according to equipment).

Changing a wheel
The jack is stowed in a box attached to the spare wheel. The assembly is secured under the vehicle by means of a winch system. The other tools are stowed in a well under the f l o o r.
Access to the tools
T y r e u n d e r - i n fl a t i o n d e t e c t i o n
The spare wheel is not fitted with a sensor. The punctured wheel must be
repaired by a CITROËN dealer or a qualified workshop.
Before doing any work on your vehicle, switch off the ignition ( Ready lamp off) to avoid any risk of injury resulting from automatic operation of the engine.
When using lifting equipment (a jack for example), take care to use the jacking points provided, so as to avoid damaging the high voltage cables.

Taking out the spare wheel
 Raise the floor to reveal the spare wheel carrier drive nut.  Turn this drive nut fully clockwise , using the wheelbrace 1 and the extension 8 , to unwind the winch cable, until the spare wheel is flat on the ground. Unwind the length needed for access to the wheel.
 Detach the assembly of wheel and box from the rear of the vehicle.  Remove the hook with its connection plate to release the assembly of wheel and box, as shown in the illustration.  Pull out the wheel for access to the box.
