2013 Citroen DS5 HYBRID4 fuel

ZEV mode *
(all electric)

Zero emissions vehicle operation is assured10 0 % by electric drive.
This mode forces silent running
at moderate speeds.
It
can be activated when therequired conditions are met, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).


Auto mode
It automatically manages the operation of theDiesel engine and the electric motor, according
to inherent vehicle parameters, traffic conditions and driving style so as to optimise
the vehicle's fuel consumption.
In particular, this mode activates "zero emissions" electric runningwhen theconditions allow.
In auto mode, the electric motor:

- can drive the vehicle on its own up to
around 36 mph (60 km/h) in "zero emissions" electric running,
depending on the state of charge of the
battery, if the conditions specific to the
vehicle are met and if acceleration is
moderate, -supplements the Diesel engine when
moving off and changing gear, duringacceleration and when traction from the front wheels is inadequate (it automatically adds4 wheel drive),

- is no longer active above 70 mph(120 km / h).



*
ZEV: Z
ero Emissions Vehicle.
This standardmode to use in preference
is activated automaticallyon starting the hybrid system.

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 inter vals your Diesel engine will produce energy for the self-cleaning of this filter.During this PEF regeneration phase, electric running is purposely made unavailable andis accompanied by a message "Electricmode not available: PEF regeneration inprogress
".
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).

Reducing consumption - Fuel
QuestionAnswer
How can I optimise m
y fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to use in
order to reduce fuel consumption.
You should also adapt
your driving style to the characteristics of hybrid vehicles to get the best
out of it, for example by taking your foot off the accelerator pedal rather than braking and by
anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Wh
y do I not manage to reduce my fuel consumption even though I often drive in ZEV(Zero Emissions Vehicle) mode?It is not ZEV mode but Auto mode that is the most appropriate
for reducing fuel consumption, as it selects the best "driving energy source".
ZEV mode (10 0% electric operation) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
This is why we recommend using Auto mode more often.
Wh
y does the trip computer sometimes displaythe bars for 28 mpg (10 litres) consumption in
town? The current fuel consumption displa
yed may appear high when the distance covered is very low,
but this generally has very little impact and the true average fuel consumption will remain low.
In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid
vehicle).
Wh
y is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode).
This allows some capacity to be left free for the recovery for energy when going downhill or takingwhen your foot off the accelerator.
Wh
y are there so may fuel aler t messages whenstarting to use the reser ve?To e n c o u r age you to refuel as soon as possible and avoid the loss of hybrid functions.

Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Eco-driving suited to your
Hybrid4 vehicle
Use gear selector position A , as thisoptimises gear changes to suit the circumstances, and the AUTOmode of theHybrid4 mode selector.When moving off, accelerate normally up tothe desired speed ( POWER
zone between20 and 40 %). At steady speeds, drive gently with smallmovements of the accelerator pedal (ECOor CHARGEzone), run in electric mode as oftenas possible when driving at low speed. Anticipate the need to slow down and useengine braking ( CHARGE
zone), so as to make use of free energy recovery while keeping light pressure on the accelerator pedal.

Before moving off, if the passenger compartment is too warm, ventilate it byopening the windows and air vents beforeusing the air conditioning.
Above 30 mph (50 km/h), close the windowsand leave the air vents open. Remember to make use of equipment that can help keep the temperature in the passenger compar tment down (sun roof andwindow blinds...).Switch off the air conditioning, unless it has automatic digital regulation, as soon as the desired temperature is attained.Switch off the demisting and defrostingcontrols, if not automatic.Switch off the heated seat as soon as possible.
Switch off the headlamps and front foglampswhen the level of light does not require their use.

Avoid running the Diesel engine when stationary, par ticularly in winter; your vehiclewill warm up much faster while driving.

As a passenger, if you avoid connecting your multimedia devices (film, music, video game...), you will contribute towards limitingthe consumption of electrical energy, and soof fuel.
Disconnect your por table devices beforeleaving the vehicle.
Control the use of your electrical equipment

Observe the recommendations
on maintenance


Check the tyre pressures regularly, whencold, referring to the label in the door aperture, driver's side.
Carry out this check in par ticular:


- before a long journey,

- at each change of season,

- after a long period out of use.



Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and obser ve the schedule of operations recommended by themanufacturer.


When refuelling, do not continue after the3 rd
cut-off of the nozzle to avoid any over flow.

At the wheel of your new vehicle, it is onlyafter the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settle down to a consistent average.


At the end of winter, remove snow tyres and refit your summer tyres.
Spread loads throughout the vehicle; placethe heaviest items in the bottom of the boot,as close as possible to the rear seats.Limit the loads carried in the vehicle andreduce wind resistance (roof bars, roof rack,bicycle carrier, trailer...). Use a roof box in preference.Remove roof bars and roof racks after use.
Limit the causes of excess
consumption

The high voltage battery must not in anycircumstances be charged from an external source and must only be handled by a
workshop technician.
There is the risk o
f 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 theelectric motor is in the range 150 to 270 Volts.
Be sure to take account of the warning labels
fitted to the vehicle.
Ta k e great care regarding the high voltage andhigh 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 restar t 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).
Be
fore doing any workon the vehicle, switch off the ignition (Readylamp off).



Battery precautions

Hi
gh 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 par ts, orange cables or connectors, even in the eventof an accident.

Underbonnet precautions / warnings

The alternator-star ter motor of your hybrid
vehicle is also supplied at high voltage. If the
vehicle ignition has not been switched off, there
is a risk of the engine restar ting at any time.
Alwa
ys ensure that the
ignition is switched off (Readylamp off) before
opening the bonnet.
Also ensure that the ignition is switchedoff when refuelling to avoid the engine restarting.
