Stop & Start
Operation
Going into engine STOP mode
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with a 5-speed electronic gearbox , with the vehicle stationary, when you press the brake pedal or put the gear lever in position N .
A time counter calculates the sum of the periods in STOP mode during a journey. It rests itself to zero every time the ignition is switched on with the key.
Special cases: STOP mode not available
STOP mode is not invoked when: - the driver's door is open, - the driver's seat belt is not fastened, - the engine is needed to maintain a comfortable temperature in the passenger compartment, - demisting is active, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
The "ECO" warning lamp flashes for a few seconds then goes off.
This operation is perfectly normal.
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.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
For your comfort, during parking manoeuvres, 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...

Maintenance
In the event of a fault with the system, the "ECO OFF" switch warning lamp flashes then comes on continuously. Have it checked by a PEUGEOT dealer or a qualified workshop.
In the event of a fault in STOP mode, the vehicle may stall. All of the warning lamps in the instrument panel come on. It is then necessary to switch off the ignition and start the engine again using the key.
Operating fault
This system requires a battery with a special specification and technology (reference numbers available from a PEUGEOT dealer or a qualified workshop). Fitting a battery not listed by PEUGEOT introduces the risk of malfunction of the system.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Start system makes use of advanced technology. All work on this type of battery must be done by a PEUGEOT dealer or a qualified workshop.
Reactivation
The system is reactivated automatically at every new start using the key.
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off, accompanied by a message in the screen.

Practical information
301-add_en_Chap09_info-pratiques_ed01-2014
On vehicle fitted with HDi engines, the fuel system must be primed if you run out of fuel; refer to the engine compartment view on the "Diesel engine" section. If the tank on your vehicle is fitted with a misfuel prevention device, refer to the corresponding section.
Running out of fuel (Diesel)
If the engine does not start first time, don't keep trying. Start the procedure again from the beginning.
 Fill the fuel tank with at least five litres of diesel.  Open the bonnet.  Squeeze and release the priming pump repeatedly until resistance is felt (there may be resistance at the first press).  Operate the starter until the engine starts (if the engine does not start at the first attempt, wait around 15 seconds before trying again).  If the engine does not start after a few attempts, operate the priming pump again then start the engine.  Close the bonnet.
HDi 92 engine
 Fill the fuel tank with at least five litres of Diesel.  Switch on the ignition (without starting the engine).  Wait around 6 seconds and switch off the ignition.  Repeat the operation 10 times.  Operate the starter to run the engine.

AdBlue ® additive and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and conformity with the new Euro 6 emissions standard, without adversely affecting the per formance or fuel consumption of Diesel engines, PEUGEOT has taken the decision to equip its vehicles with an effective system that associates SCR (Selective Catalytic Reduction) with a particle filter (FAP) for the treatment of exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue ® containing ® containing ®
urea, a catalytic converter turns up to 85% of nitrous oxides (NOx) into nitrogen and water, which are harmless to health and the environment.
The AdBlue ® additive is held in a special ® additive is held in a special ®
tank located under the boot at the rear of the vehicle. It has a capacity of 17 litres: this provides a driving range of about 12 500 miles (20 000 km), after which an alert is triggered warning you when the reserve remaining is enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle by a PEUGEOT dealer or a qualified workshop, the AdBlue ® additive tank is refilled in order to ® additive tank is refilled in order to ®
allow normal operation of the SCR system.
If the estimated mileage between two services is greater than 12 500 miles (20 000 km), we recommend that you go to a PEUGEOT dealer or a qualified workshop to have the necessary top-up carried out.
Once the AdBlue ® tank is empty, a ® tank is empty, a ®
system required by regulations prevents starting of the engine. If the SCR is faulty, the level of emissions from your vehicle will no longer meet the Euro 6 standard: you vehicle becomes polluting. In the event of a confirmed fault with the SCR system, you must go to a PEUGEOT dealer or a qualified workshop as soon as possible: after a running distance of 650 miles (1 100 km), a system will be triggered automatically to prevent engine starting.

detection of a fault with the SCR emissions control system, when the ignition is switched on, an indicator displays an estimate of the distance that can be covered, the range, before engine starting is prevented. In the event of simultaneous system fault and low AdBlue ® level, the shortest range figure is ® level, the shortest range figure is ®
