- F u l l y d e p r e s s t h e b r a k e p e d a l .
- A c t i o n t h e s t a r t e r .
- W i t h t h e e n g i n e r u n n i n g , d e p e n d i n g on your preference place the lever on R, A or M.
- C h e c k t h e p o s i t i o n e n g a g e d o n t h e rev counter.
- R e l e a s e t h e h a n d b r a k e .
- R e l e a s e t h e b r a k e p e d a l a n d accelerate.
If the lever is not in position N, the warning lamp "N" fl a s h e s o n t h e r e v counter.
If the brake pedal is not pressed down, the warning lamp "Foot on brake" fl a s h e s i n t h e i n s t r u m e n t panel.
In both cases, the engine does not start; recommence the above procedure.
Note: If the vehicle has been stationary for a long time, or if you have pressed the brake pedal a number of times while stationary, it will be necessary to press the brake pedal hard down in order to authorise the engine to start.
Stopping the engine
Before switching the engine off, you can choose:
- t o l e a v e t h e v e h i c l e i n n e u t r a l ; f o r that, place the lever in position N,
- t o l e a v e t h e v e h i c l e w i t h a g e a r engaged (R, A or M); for that, place the lever in the position chosen. In this case, the vehicle cannot be moved.
In all cases, it is essential to apply the handbrake.
Before undertaking any operation in the engine compartment, make absolutely sure that the gearbox is in neutral and that the handbrake is on.
Do not hold the vehicle stationary using only the accelerator.
If you are stopped on an incline, use the handbrake to hold the vehicle.
Acceleration
To obtain optimum acceleration (for example to overtake another vehicle), you have only to press the pedal hard down to go beyond the e n d - o f - t r a v e l s w i t c h .

Manual mode
Position the gear lever in position M, then:
- p u s h t h e l e v e r t o e n g a g e a h i g h e r gear,
- p u l l t h e l e v e r t o c h a n g e d o w n .
Manual mode with controls behind the steering wheel
Place the gear lever in position M, and then the controls at the steering wheel will give you access to the six gears in forward drive.
To change gear:
- P r e s s b e h i n d t h e c o n t r o l "+" at the steering wheel to engage a higher gear.
- P r e s s b e h i n d t h e c o n t r o l "-" at the steering wheel to change down.
Observations:
When the vehicle is braking or reducing speed, the gearbox changes down automatically to a suitable gear.
In manual mode, it is not necessary to release the accelerator during changes of gear.
C h a n g e s o f g e a r a r e a c c e p t e d o n l y if consistent with engine speed.
Under heavy accelera-tion, a higher gear will only be engaged when the driver actions the gear lever or the controls at the steering wheel.
Note: These controls at the steering do not permit you to select neutral or reverse gear.

Drive
The gearbox always selects the gear best adapted to the following parameters:
- s t y l e o f d r i v i n g ,
- r o u t e p r o fi l e ,
- v e h i c l e l o a d .
In this way the gearbox operates in autoadaptive mode, without the need for your intervention.
For certain manoeuvres (for example overtaking), it is possible to ob tain maximum acceleration by pressing hard down on the accelerator pedal, which may trigger automatic changedown to a lower gear.
Note
During braking, the gearbox may kick down automatically in order to offer an effective engine brake.
If you rapidly lift your foot off the accelerator, the gearbox will guard your safety by not changing up again.
Sequential forward drive
Selector position for manual gear changing.
- S e l e c t o r a t M.
- P u s h t h e s e l e c t o r t o w a r d s t h e s i g n "+" to change up a gear.
- P u l l t h e s e l e c t o r t o w a r d s t h e s i g n "-" to change down a gear.
Note: Passage from one gear to another is only possible when vehicle speed and engine speed permit.
The Sport and Snow programmes are not operative in sequential mode.
The change from position D (drive in automatic mode) to position M (drive in sequential mode) or vice versa may be effected at any time.

This driving assistance device allows you to select a maximum speed that you wish not to exceed. This has to b e a s p e e d g r e a t e r t h a n 3 0 k m / h ( a p p r o x . 2 0 m p h ) .
The speed limiter controls are located on the steering wheel.
Note: The information relating to the limiter is displayed in zone A of the instrument panel.
To select the function
Turn control 1 to position "LIM".
On selection of the function, the last speed memorised and the information "OFF" will appear:
To adjust the maximum speed
Provided the engine is running, you can adjust the memorised maximum speed, with short or long presses on:
- b u t t o n 4 to increase the memorised maximum speed,
- b u t t o n 2 to decrease the memorised maximum speed.
Note: successive presses modify the memorised speed in steps of 1 k m / h ( 1 m p h ) , a c o n t i n u o u s p r e s s i n s t e p s o f 5 k m / h ( 3 m p h ) .
Activation of the maximum speed
When the desired maximum speed is displayed, press button 3 to activate the limitation.
The information "OFF" then disappears from zone A.
While the function is active, pressing the accelerator pedal will not enable you to go beyond the programmed speed unless you press the pedal hard down past the tight spot (see "Temporary exceeding of the maximum speed").
Note: The vehicle speed may vary slightly from that memorised.

Radiator - coolant
The coolant must only be checked or topped up if the power unit is cold.
Engine hot
As the cooling system is pressurised, wait for at least one hour after switching off the engine before intervening.
To avoid the risk of scalding, slacken the cap two turns to allow the pressure to escape. Once the pressure has fallen, remove the cap and top up the level.
Adding engine oil
Remove the dipstick before topping up. C h e c k t h e l e v e l a f t e r fi l l i n g .
