Coolant temperature gauge
With the engine running:
- 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
the engine.
Contact a CITROËN dealer or a qualified
workshop.
A
fter 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 "MAX" mark.
Be aware of the risk of burns whentopping up the cooling system. Do not fill above the maximum level (indicated on the reservoir).

Comfort
4. Automatic visibilityprogramme
For maximum cooling or heating of thepassenger compar tment, 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
g - defrosting".
2-3. Driver's-passenger's side
settings
The driver and front passenger can each adjust the temperature to their requirements.
The value indicated on the display corresponds to a level of comfor t and not to a
temperature in degrees Celsius or Fahrenheit.
)Turn control 2or 3to the left or to the right respectively to decrease or increase this
value.
A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 isnormal.
You are advised to avoid a left /right settingdifference of more than 3.
Manual operation
If you wish, you can make a different choice from that offered by the system by changing asetting. The "AUTO"
indicator lamps go off;
the other functions, except the air conditioning,
will still be controlled automatically.
) Pressing the "AUTO"
button returns the system to completely automatic operation.
With Stop & Star t, when demisting hasbeen activated, the STOP mode is not available.

211Practical 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 exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Refer to the "Technical Data" section for detailsof 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 inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and theSTOPwarning 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 long
mountain type of descent, the use of engine
braking is recommended.
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 genuineCITROËN towbar is used.

Coolant level
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 thefan. 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 en
gine is cold.
Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to themanufacturer's recommendations.
Power steering fluid level
The power steering fluid level should be close to the "MA X" mark. With
the engine cold, unscrew the cap to check the level. Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the ser vicing booklet for details of the
interval for this operation.
Fluid specifi cation
The brake fluid must conform to themanufacturer's recommendations and meet the
DOT4 standard.
In addition, as the cooling system ispressurised, wait at least one hour after
switching off the engine before carrying out any work.To a v o i d a ny risk of scalding, unscrewthe cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and topup the level.
