fuel reserve Citroen DS5 HYBRID4 2012 1.G Owner's Manual

Automatic restarting of the Diesel engine or ZEV mode NOT available

Maintaining the performance of
the system



- When the vehicle exceeds 18 mph(30 km/h) after moving off (if the internal
combustion engine has not already star ted since the vehicle was last star ted).

- If the high voltage battery is not sufficiently charged. A minimum of 4 barsin ZEV mode so as to ensure operationover a cer tain distance (in AUTO, electricoperation is accessible for a shor ter period with a lower level of charge).

- When the fuel level enters the reservezone (where rate of consumption of this reser ve is high, ZEV inhibition may continue for some time after refuelling).

- During regeneration of the particleemissions filter, which occursautomatically for 5 to 10 minutes,approximately every 300 miles (500 kms)(or less in extended urban running).

The internal combustion engine may restar t or
ZEV mode may not be available in the variousconditions presented below. The internal combustion engine can beswitched off automatically as soon as these
conditions are lifted. When the conditions described below causethe vehicle to come out of ZEV mode andthe Diesel engine to restar t, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in par ticular the Particle Emissions Filter (PEF).
At regular intervals your Diesel engine will produce energy for the self-cleaning of this filter.During this PEF regeneration phase, electric running is purposely made unavailable.
Action by the driver
- Moving the gear selector to position M
. - Action on steering mounted control paddles to change gear.- Sustained and sharp acceleration. - Use of demisting.- Use of air conditioning.


Diffi cult weather conditions and
circumstances



- If cer tain conditions or engine temperature requirements make it necessary (such as
an engine temperature that is too low for the ambient conditions).

- When the battery is close to maximumcharge (for example: when going down a long hill), because engine recoverybeing no longer possible, the internalcombustion engine restar ts automatically just to provide engine braking.

- If the vehicle encounters a steep slope(car park ramp, ...).

- If the vehicle has been parked in the sunfor a prolonged period.

- When driving in mountainous conditions(altitude).
