Monitoring
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 comfort value, there is no need to change the value displayed in order to obtain the comfort 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 compartment, 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 comfort value on the passenger's side with that on the driver's side (mono-zone). The indicator lamp in 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
performance.
7. Maximum air conditioning
If you want to temporarily refresh the air in the passenger compartment, press this button and "LO" is displayed. To return to the previous settings, press the button again.
With Stop & Start, 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 discomfort (humidity, misting).

If you wish, you can change one of settings provided by the system. The other functions will still be controlled automatically. Press one of the Soft /Auto/Fast buttons to return to fully automatic operation.
On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is no need to change the value displayed in order to obtain the comfort required. The system corrects the difference in temperature automatically and as quickly as possible.

Press this button to apply the driver's comfort setting value to the front and rear passengers (mono-zone). The indicator lamp on the button comes on.
The air conditioning is designed to operate effectively in all seasons, with the windows closed. It allows you:
- in summer, to lower the temperature, - in winter, above 3°C, to improve demisting performance.

For maximum cooling or heating of the passenger compartment, it is possible to exceed the minimum value 14 or the maximum value 28.  Turn the dial 3 or 4 to the left until "LO" is displayed or to the right
until "HI" is displayed.
With Stop & Start, when demisting has been activated, the STOP mode is not available.

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.
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. To avoid overheating of the brakes on a long mountain type of descent, the use of engine braking is recommended.
Ty r e s
 Check the tyre pressures of the towing vehicle and of the trailer, observing 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.
Refer to the "Technical Data" section for details of the weights and towed loads which apply to your vehicle.

Checks
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
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 replaced at routine services.
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 Screenwash and headlamp wash fluid Screenwash and headlamp
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.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health or indeed very corrosive.
Do not discard used oil or fluids into sewers or onto the ground. Take used oil to a PEUGEOT dealer or a qualified workshop (France) or to an authorised waste disposal site.

Topping up
This additive must be topped up by a PEUGEOT dealer or a qualified workshop without delay.
Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by illumination of the service warning lamp, accompanied by an audible warning and a message in the instrument panel screen. When the engine is warm, the temperature of the coolant is regulated by the fan. Top up the reservoir when you next stop the vehicle.
