Situations where the engine does not shut down:
Before shutting down the engine, the system automatically and instantly checks that a certain number of conditions touching on safety, cabin comfort or engine protection are met .
For example, the engine will not shut down, or it will restart by itself:Within the few minutes following fi rst starting (engine col d).If the temperature in the passenger compartment is insuffi cient:
In conditions of extreme outside temperatures (lower than -10°C, higher than +30°C), provided the air condition-ing is operating.More generally, if the ambient conditions and the temperature programmed for the air conditioning make it nec-essary for the engine to be running in order to produce eithe r warm or cold air.If you have activated windscreen demisting/deicing.
In the event of a prolonged stop on a steep incline, in order to maintain the vehicle's braking capability.
After you have engaged reverse gear, engine shutdown is suspend ed for approx. fi fteen seconds.

Air inlet
Check that the exterior grille for the air inlet, at the bot-tom of the windscreen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.
Air vents
The air vents to the face (except the central air vent) have grilles for orienting the fl ow of air (up-down, right-left).
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
Air outlets are also located on the central console close to the gear lever, to enhance comfort for the rear pas-sengers.
Pollen fi lter – Odour fi lter
Your installation has a fi lter for keeping out dust.
This fi lter has to be changed according to the vehicle maintenance schedule. See “Maintenance Guide”.
Air conditioning
Whatever the time of year, even in cool weather the air conditioning is useful in removing humidity and mist-ing.
To keep the air conditioning compressor well sealed, it is essential to operate the air conditioning at least once in every month.
To be effective, the air conditioning should only be used with the windows closed.
If you are towing a heavy trailer and outside tempera-tures are high, the air conditioning may be temporarily paused if the engine cooling requires this.
Water arising from condensation in the air conditioning system is evacuated through a hole provided for this purpose ; a pool of water may thus form underneath the vehicle when stationary.
You are advised to have the air conditioning system checked on a regular basis. See “Maintenance Guide”.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
Demisting - deicing of the wind-screen and front side windowsPlace the controls for temperature and air fl ow on maximum.
Close the central air vents.
Operate the air conditioning.Note: You should not be in air recirculation.

Air conditioning
The air conditioning only operates when the engine is running.
Press the control located on the control panel.
Warning lamp on = in operation
Air conditioning is obtained by the mixing of hot air and cold air. Control 4 allows you to adjust the air conditioning while control 5 is in operation.
To obtain refrigerated air, you should check that the air blower control 3 is not on position “0”.
Air recirculation
This function isolates the passen-ger compartment from disagree-able odours or smoke coming from outside and increases the effi ciency and rapidity of the air conditioning.
According to version, press on control A (warn-ing lamp comes on), or move control B.
The entry of air from outside is blocked.
This function should be cancelled when no longer needed in order to permit a renewal of cabin air and to prevent misting.Note: To obtain a rapid rise in cabin tempera-ture, place control A or B in the air recircula-tion position and control 4 on maximum in the 4red zone.
If after a prolonged stop in bright sunlight, the cabin temperature is very high:Open the windows for a few moments to let in air, then cl ose the windows again.Adjust the temperature on control 4 to the maximum cold posi-tion.
Open the air vents.Use the recycled cabin air position.
Place the air blower control 3 to the position close to maxi-mum.
With comfort restored, action the air blower 3 and the tempera-ture control 4 to adjust comfort.

Check that the assisting battery has suffi cient voltage (12 V).
If you use the battery on another vehicle, stop the engine on the latter. The two vehicles must not come into direct contact wit h each other.
Connect the cables according to the order indicated in the dia-ordergram. Check that the leads are well secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine run for around 1 minute at a slightly accelerated idle.
