Instruments and controls
Coolant temperature gauge
With the engine running, when the needle is: - in zone A , the temperature is correct, - in zone B , the temperature is too high; the central STOP warning lamp comes on, accompanied by an audible signal and a message in the instrument panel screen. You MUST stop as soon as it is safe to do so. Wait a few minutes before switching off the engine. Contact a PEUGEOT dealer or a qualified workshop.
After driving for a few minutes, the temperature and pressure in the cooling system increase. To top up the level:  wait for the engine to cool,  unscrew the cap by two turns to allow the pressure to drop,
 when the pressure has dropped, remove the cap,  top up the level to the "MA X" mark.
On switching on the ignition or when driving, it indicates the engine oil temperature. With the needle in zone C , the temperature is correct. With the needle in zone D , the temperature is too high. Slow down to lower the oil temperature.

Comfort
On entering the vehicle, if the interior temperature is much colder or warmer than the comfor t value, there is no need to change the value displayed in order to obtain the comfor t required. The system corrects the difference in temperature automatically and as quickly as possible.
4. Automatic visibility programme
For maximum cooling or heating of the passenger compar tment, it is possible to exceed the minimum value 14 or the maximum value 28.  Turn control 2 or 3 to the left until "LO" is displayed or to the right until "HI" is displayed.
See "Front demisting-defrosting".
 Press this button to equalise the comfor t value on the passenger's side with that on the driver's side (mono-zone). The indicator lamp on the button comes on.
If you wish, you can change one of settings provided by the system. The other functions will still be controlled automatically.  Pressing the "AUTO" button returns the system to completely automatic operation.
Manual operation
5. Mono-zone/Dual-zone
The air conditioning is designed to operate effectively in all seasons, with the windows closed.
6. Air conditioning On/Off
It allows you: - in summer, to lower the temperature, - in winter, above 3 °C, to improve demisting per formance.
7. Maximum air conditioning
If you want to temporarily refresh the air in the passenger compar tment, press this button and "LO" is displayed. To return to the previous settings, press the button again.
With Stop & Star t, when demisting has been activated, the STOP mode is not available.
Switching on Press the "A /C" button, the associated
green indicator lamp comes on. The air conditioning does not operate when the air flow control is set to off.
Switching off Press the "A /C" button again, the associated green indicator lamp goes off. Switching off the air conditioning may result in some discomfor t (humidity, misting).

Practical information
Driving advice
Distribution of loads
 Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight approaches the maximum permitted without exceeding it. Air density decreases with altitude, thus reducing engine per formance. Above 1 000 metres, the maximum towed load must be reduced by 10 % for every 1 000 metres of altitude. Refer to the "Technical Data" section for details of the weights and towed loads which apply to your vehicle.
Side wind
 Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.  To lower the engine speed, reduce your speed. The maximum towed load on a long incline depends on the gradient and the ambient temperature. In all cases, keep a check on the coolant temperature.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
Tyres
 Check the tyre pressures of the towing vehicle and of the trailer, obser ving the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be deactivated automatically if a genuine PEUGEOT towbar is used.

Checks
The coolant level should be close to the "MA X" mark but should never exceed it. When the engine is warm, the temperature of the coolant is regulated by the fan. This can operate with the ignition off. On vehicles which are fitted with a par ticle emission filter, the fan may operate after the vehicle has been switched off, even if the engine is cold.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations. Fluid specifi cation
For optimum cleaning and to avoid freezing, this fluid must not be topped up with or replaced with plain water.
Screenwash and headlamp
wash fluid
In the case of vehicles fitted with headlamp washers, the low fluid level is indicated by an audible signal and a message in the instrument panel screen. Top up the reser voir when you stop the vehicle.
