Driving
Never select position N while the vehicle is moving. Never select positions P or R unlessthe vehicle is completely stationary.
Automatic operation
 Select position D for automatic changing of the six gears. The gearbox then operates in auto-adaptive mode, without any inter vention on the par t of the driver. It continuously selects the most suitable gear according to the style of driving, the profile of the road and the load in the vehicle. For maximum acceleration without touching the lever, press the accelerator pedal down fully (kick down). The gearbox changes down automatically or maintains the gear selected until the maximum engine speed is reached. On braking, the gearbox changes down automatically to provide efficient engine braking. If you release the accelerator sharply, the gearbox will not change to a higher gear for safety reasons.
Sport and snow programmes
Sport programme "S"
 Press button "S" , after star ting the engine. The gearbox automatically favours a dynamic style of driving.
S appears in the instrument panel.
Snow programme "  "
 Press button "  ", after star ting the engine. The gearbox adapts to driving on slippery roads. This programme improves star ting and drive
when traction is poor.
 appears in the instrument panel.
Return to automatic
operation
 At any time, press the button selected again to quit the programme engaged and return to auto-adaptive mode.
These two special programmes supplementthe automatic operation in very specific conditions of use.

Manual operation
 Select position M for sequential changing of the six gears.  Pull the lever towards the + sign to change up a gear.  Push the lever towards the - sign to change down a gear. It is only possible to change from one gear to another if the vehicle speed and engine speed permit; other wise, the gearbox will operate temporarily in automatic mode.
D disappears and the gears engaged appear in succession on the instrument panel.
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.
Operating fault
When the ignition is on, a message appears in the instrument panel screen to indicate a gearbox 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 Pto R and from N to R . This 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.
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 spor t and snow programmes do not operate in manual mode.
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. If the lever is not in position 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.
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.

Manual gear changing
 When the vehicle has moved off, select position M to change to manual mode. - Pull the lever towards the + sign to change up a gear. - Push the lever towards the - sign to change down a gear.
At very low speed, if reverse gear is requested, this will only be taken into account when the vehicle is immobilised. The Foot on brake warning lamp may flash in the instrument panel to prompt you to brake.
On sharp acceleration, the gearbox will not change up unless the driver acts on the gear lever or the steering mounted paddles. Never select neutral N while the vehicle is moving. Only engage reverse gear R when the vehicle is immobilised with the brake pedal pressed.
A disappears and M appears with the gears engaged successively, in the instrument panel screen.
The gear change requests are only carried out if the engine speed permits. It is not necessary to release the accelerator during gear changes. When braking or slowing down, the gearbox
changes down automatically to permit acceleration in the correct gear.
This selective gear change mode enables you to over take, for example, while still remaining in automatic mode.  Operate the + or - steering mounted control paddle. The gearbox engages the gear requested ifthe engine speed permits. A is still displayed in the instrument panel.
After a few moments without any action on the controls, the gearbox resumes automatic control of the gears.

Driving
You must press the brake pedal when star ting the engine. Whatever the circumstances, you must manually apply the parking brake when parking, unless the parking brake is programmed in automatic mode.
When immobilising the vehicle, with the engine running, you must place the gear lever in neutral N . Before carrying out any work in the engine compar tment, check that the gear lever is in neutral N and that the parking brake is applied.
Stopping the vehicle
With the ignition on, the flashing of this warning lamp, accompanied by an audible signal and a message in the instrument panel screen, indicates a malfunction of the gearbox. Have it checked by PEUGEOT or a qualified workshop.
Before switching off the engine, you can choose to: - move to position N to engage neutral, - leave the gear engaged; in this case, it will not be possible to move the vehicle. In both cases, you must apply the parking brake to immobilise the vehicle.

Stop & Start
The Stop & Star t system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as y ou want to move off. The restar t takes place instantly, quickly and silently. Per fect for urban use, the Stop & Star t system reduce s fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with the electronic gear control gearbox, at speeds below 4 mph (6 km/h), press the brake pedal or put the selector 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 rests itself to zero every time the ignition is switched on with the key.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
For your comfor t, 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...
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 vehicle has not exceeded 6 mph (10 km/h) since the last engine star t using the key, - the electric parking brake is applied or being applied, - the engine is needed to maintain a comfor table temperature in the passenger compar tment, - 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. In this case, the "ECO" warning lamp flashes for a few seconds then goes off. This operation is per fectly normal.

The system is reactivated automatically at every new star t using the key.
Reactivation
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off and a message in the screen.
Operating fault
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. It is then necessary to switch off the ignition and star t the engine again using the key.
Before doing anything under the bonnet, deactivate the Stop & Star t system to avoid any risk of injury resulting from automatic operation of START mode.
This system requires a 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.
Maintenance
The Stop & Star t 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.

Hill start assist
System which keeps your vehicle immobilised temporarily (approximately 2 seconds) when star ting on a gradient, the time it takes to move your foot from the brake pedal to the accelerator pedal. This system only operates when: - the vehicle is completely stationary, with your foot on the brake pedal, - in par ticular conditions on a slope, - with the driver’s door closed. The hill star t 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: - provided you are in first gear or neutral on a manual gearbox, - provided you are in A or M on an electronic gear control gearbox, - provided you are in D or M on an automatic gearbox.
Operation
On a descending slope, with the vehicle stationar y and reverse gear engaged,the vehicle is held momentarily when you release the brake pedal.
Do not exit the vehicle while it is being held in the hill star t assist phase. If you need to exit the vehicle with the engine running, apply the parking brake manually then ensure that the
parking brake warning lamp (and the warning lamp P in the lever of the electric parking brake) are on fixed (not flashing).
Operating fault
If a fault in the system occurs, these warning lamps come on. Contact a PEUGEOT dealer or a qualified workshop to have the system
checked.
