Monitoring
Engine oil level indicator
On versions fitted with an electric oil gauge, information on the oil level is displayed in the instrument panel for a few seconds when the ignition is switched on, at the same time as the service information.
The level read will only be correct if the vehicle is on level ground and the engine has been off for more than 30 minutes.
Oil level correct
This is indicated by a message in the instrument panel.
Oil level incorrect
This is indicated by a message in the instrument panel. If the low oil level is confirmed by a check using the dipstick, the level must be topped up to avoid damage to the engine.
Oil level indicator fault
This is indicated by a message in the instrument panel. Contact a PEUGEOT dealer or a qualified workshop.
Dipstick
There are 2 marks on the dipstick: - A = max; never exceed this level, - B = min; top up the level via the oil filler, using the grade of oil suited to your engine.
Refer to the "Checks" section to locate the dipstick and the oil filler cap on your engine.

Access
Low fuel level
When the low fuel level in the tank is reached, this warning lamp comes on in the instrument panel, accompanied by an audible warning and a message.
Fuel supply cut-off
Your vehicle is equipped with a safety device which cuts off the fuel supply in the event of a collision.
It is still possible to use a fuel can to fill the tank but this must be done slowly. In order to ensure a good flow of fuel, do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device.
Diesel misfuel prevention
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong fuel. Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the fuel filler neck of your Diesel vehicle, it comes into contact with the flap. The system remains
closed and prevents filling. Do not persist but introduce a Diesel filler nozzle.
Operation
Travelling abroad
As Diesel fuel pump nozzles may be different in other countries, the presence of the misfuel prevention device may make refuelling impossible. Before travelling abroad, we recommend that you check with the PEUGEOT dealer network, whether your vehicle is suitable for the fuel pumps in the country in which you want to travel.
When it first comes on, less than 10 litres of fuel remain in the tank. You must refuel as soon as possible to avoid running out.
If you have put in the wrong fuel for your vehicle, you must have have the tank drained and refilled with the correct fuel before you star t the engine.
Your vehicle is fitted with a catalytic converter, a device which helps to reduce the level of harmful emissions in the exhaust gases. For petrol engines, you must use unleaded fuel only. The filler neck is narrower, admitting petrol nozzles only.

230 V / 50 Hz power socket
A 230 V / 50 Hz socket (maximum power: 120 W) is fitted in the rear storage box. This socket works with the engine running, as well as in STOP mode with Stop & Start.  Open the central storage box,  Check that the warning lamp is on green,  Connect your multimedia or other electrical device (telephone charger, laptop computer, CD-DVD player, baby food warmer...).
In the event of a fault with the socket, the green warning lamp flashes. Have it checked by a PEUGEOT dealer or a qualified workshop.
Connect only one device at a time to the socket (no extension or multi-way connector). Connect only devices with class II insulation (shown on the device). Do not use a device with a metal case. As a safety measure, when electrical consumption is high and when required
by the vehicle's electrical system (particular weather conditions, electrical overload...), the current supply to the socket will be cut off; the green warning lamp goes off.
The different "ports and sockets" can be either not available, an option or standard, depending on the trim level of the vehicle.

Comfort
In order for these systems to be fully effective, follow the operation and maintenance guidelines below:  To obtain an even air distribution, take care not to obstruct the exterior air intake grilles located at the base of the windscreen, the nozzles, the vents and the air outlets, as well as the air extractor located in the boot.  Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the air conditioning system.  Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month to keep it in per fect working order.  Ensure that the passenger compartment filter is in good condition and have the filter elements replaced regularly. We recommend the use of a combined passenger compartment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by the occupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad odours and greasy deposits).  To ensure correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the warranty and maintenance record.  If the system does not produce cold air, switch it off and contact a PEUGEOT dealer or a qualified workshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the passenger compartment for a few moments. Put the air flow control at a setting high enough to quickly change the air in the passenger compartment.
The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.
When towing the maximum load on a steep gradient in high temperatures, switching off the air conditioning increases the available engine power and so improves the towing ability.
Stop & Start
The heating and air conditioning systems only work when the engine
is running. To maintain a comfortable temperature in the passenger compartment, you can temporarily deactivate the Stop & Start system (see the corresponding section).

Hill start assist
System which keeps your vehicle immobilised temporarily (approximately 2 seconds) when starting on a gradient, the time it takes to move your foot from the brake pedal to the accelerator pedal. This system is either not available or is standard. It only operates when: - the vehicle is completely stationary, with your foot on the brake pedal, - particular conditions on a slope are met, - with the driver’s door closed. This hill start assist system cannot be deactivated.
On an ascending slope, with the vehicle stationary, the vehicle is held for a momentarily when you release the brake pedal: - if you are in first gear or neutral with a manual gearbox, - if you are in position D or M with an automatic gearbox.
Operation
On a descending slope, with the vehicle stationary and reverse gear engaged, the vehicle is held momentarily when you release the brake pedal.
Operating fault
If a fault in the system occurs, this warning lamp comes on accompanied by a message. Contact a PEUGEOT dealer or a qualified workshop to have the system checked.
Do not leave the vehicle while it is being held in the hill start assist phase. If you need to get out of the vehicle with the engine running, apply the parking brake manually then ensure that the parking brake indicator lamp (and the P indicator lamp in the electric parking brake control lever) are on fixed (not flashing).

If the engine speed is too low or too high, the gear selected flashes for a few seconds, then
the actual gear engaged is displayed. It is possible to change from position D(automatic) to position M (manual) at any time. When the vehicle is stationary or moving very slowly, the gearbox selects gear M1automatically. The sport and snow programmes do not operate in manual mode.
Manual operation
Invalid value during manual operation
This symbol is displayed if a gear is not engaged correctly (selector between two positions).
Stopping the vehicle
Before switching off the engine, you can engage position P or N to place the gearbox in neutral. In both cases, apply the parking brake to immobilise the vehicle, unless it is programmed
to automatic mode.
If the lever is not in position P , when the P , when the Pdriver's door is opened or approximately 45 seconds after the ignition is switched off, there is an audible signal and a message appears.  Return the lever to position P ; the audible signal stops and the message disappears.
When the ignition is on, a message appears in the instrument panel screen to indicate a gearbox fault.
Operating fault
In this case, the gearbox switches to back-up mode and is locked in 3rd gear. You may feel a substantial knock when changing from P to R and from R and from RN to R . R . RThis will not cause any damage to the gearbox. Do not exceed 60 mph (100 km/h), local speed restrictions permitting. Have it checked by a PEUGEOT dealer or a qualified workshop.
You risk damaging the gearbox: - if you press the accelerator and brake pedals at the same time, - if you force the lever from position Pto another position when the battery is flat.
To reduce fuel consumption when stationary for long periods with the engine running (traffic jam...), position
the gear lever at N and apply the parking brake, unless it is programmed in automatic mode.

Reactivation
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.
Operating fault
In the event of a fault with the system, this warning lamp 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 instrument panel warning lamps come on. Depending on version, an alert message may also be displayed, asking you to place the gear lever in position N and put your foot on the brake pedal. You must switch off the ignition, then start the engine again.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
This system requires a 12 V battery with a special specification and technology (reference numbers available from PEUGEOT dealers). Fitting a battery not listed by PEUGEOT introduces the risk of malfunction of the system. For charging, use a 12 V charger and do not reverse the polarity.
Maintenance
The Stop & Start system makes use of advanced technology. For any work on the system go to a qualified workshop with the skills and equipment required,
which a PEUGEOT dealer is able to provide.
