Stop & Start
Operation
Going into engine STOP
mode
The "E cO" warning lamp comes on
in the instrument panel and the engine
goes into standby automatically:
-

w

ith a manual gearbox, at speeds below
12 mph (20 km/h) or vehicle stationary with
the BlueHDi 115 and 120 versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

w

ith an electronic gearbox, at speeds
below 5 mph (8 km/h), when you press
the brake pedal or put the gear lever in
position


N,
-

w

ith an automatic gearbox, vehicle
stationary, when you press the brake pedal
or put the gear lever in position N .If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets itself
to zero every time the ignition is
switched on with the START/STOP
button.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the START/STOP button. For your comfort, during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...
The Stop & Start
system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The

engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when
stationary.
driving

The electronic power super visor (4)
manages the operation of the two power units, HDi Diesel and electric, giving priority to low fuel consumption.
The alternator-starter motor (5) assures the
Stop & Star t function, which allows the HDi Diesel engine to be put into standby when the vehicle is at a standstill (traffic lights, a stop, or in a traffic jam...) or during phases of running in 100% electric mode. The stopping and restarting of the HDi Diesel engine is done automatically and instantly without any action on the part of the driver. This alternator-starter motor also provides additional charging of the high-voltage battery by the HDi Diesel engine, if this not sufficiently charged, or in 4WD mode for example.
The 12 V batter y , located under the bonnet, 12 V batter y , located under the bonnet, 12 V batter y
powers the vehicle's conventional electrical system. It is used for starting the HDi Diesel engine and the operation of the vehicle's equipment, such as the lighting, wipers, audio system... This 12 V battery is recharged automatically by the high voltage network.

Starting the Hybrid4
system
Activation of the Hybrid4 system
On activation of the Hybrid4 system, the instrument panel lights up, the power indicator needle is placed at position " 0 ". The steering column automatically unlocks (perceptible noise and movement of the steering column). Depending on certain parameters, such as the state of charge of the high voltage battery or the ambient temperature, the Hybrid4 system itself determines whether it is necessary to start the HDi Diesel engine. The mode selector is at the AUTO p o s i t i o n .
In wintry conditions with the engine cold, the Diesel pre-heating warning lamp can stay on for a few seconds; wait until it goes off before releasing the brake pedal.
Starting - switching off the Hybrid4 system
Never leave children alone inside the vehicle when the Hybrid4 system is a c t i v e .
 Place the gear selector at position N .  Insert the electronic key in the reader. or  With Keyless Entry and Starting, simply having the electronic key inside the vehicle is sufficient.
 Press the brake pedal firmly.  Make a single short press (about one second) on the " START/STOP " button.  Maintain pressure on the brake pedal until the RE ADY lamp comes on, signalling RE ADY lamp comes on, signalling RE ADYactivation of the Hybrid4 system, confirmed by an audible signal.
If the Hybrid4 system does not start up:  If N is flashing in the instrument panel, move the gear selector to position A then to position N .  If the " Foot on the brake " is displayed, press the brake pedal

39Frequently asked questions
DS5Hy4_en_Chap11_questions-frequentes_ed01-2015
Reducing consumption / Fuel
QuestionAnswer
How can I optimise my 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 which allows the recovery of "free" energy for charging the battery (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why 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 (100% electric running) 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.
Why does the trip computer sometimes display the bars for 28 mpg (10 litres/100 km) in town? In traffic jams, the fuel consumption graph displayed may temporarily 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 urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption (by around 35%) compared to a conventional vehicle.
Why 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 taking when your foot off the accelerator.
Why are there so may fuel alert messages when starting to use the reserve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all electric running.
