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 amessage in the instrument panel screen.You MUST stop as soon as it is safe to do so.
Wait a few minutes before switching off theengine.
Contact a PEUGEOT dealer or a qualified
wor
kshop.
After drivin
g for a few minutes, the temperatureand 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 noneed to change the value displayed in order to obtain the comfort required.The system corrects the differencein temperature automatically and asquickly as possible.

4. Automatic visibility programme

For maximum cooling or heating of thepassenger compartment, it is possibleto exceed the minimum value 14 or themaximum value 28.)
Turn control 2or 3
to the left until "LO"is displayed or to the right
until "HI"
is displayed. See "Front demistin

)
Press this button to equalise thecomfort value on the passenger's
side with that on the driver's side (mono-zone). The indicator lamp in the button comes on.

I
f 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 demistin
gperformance.


7. Maximum air conditioning
If you want to temporarily refresh theair in the passenger compartment,
press this button and "LO"isdisplayed.
To return to the previous settings, press the
button again.
With Stop & Start, when demisting has been activated, the STOP mode is notavailable.Switchin
g 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).

Practical information
Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
excee
ding it.
Air density decreases with altitude, thus reducingengine performance. 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

To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y 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

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a longmountain type of descent, the use of engine braking is recommended.


Tyres
)Check the tyre pressures of the towingvehicle 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.
R
efer 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 closeto the "MA X" mark but should never exceed it.When the engine is warm,
the temperature of the coolant is regulated
by the fan.
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 an
y risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.When the pressure has dropped, remove thecap 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 anda message in the instrument panelscreen.
Top up the reser voir when you next stop the
vehicle. The cooling fan may star t after switchingoff the engine: take care with ar ticles andclothing that might become caught by thefan blades.
