Load reduction mode
System which manages the use of certainfunctions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates cer tain functions, such as the air conditioning,
the heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
System which manages the duration of use of
certain functions to conserve a sufficient level
of charge in the battery.
After the engine has stopped, you canstill use functions such as the audio and
telematics system, windscreen wipers, dipped
beam headlamps, cour tes
y lamps, etc. for a maximum combined duration of about forty minutes.

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 performance. Above
1 000 metres, the maximum towed load must
be reduced b
y 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 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.

Checking levels


Take care when working under thebonnet, as certain areas of the enginemay be extremely hot (risk of burns).
Oil level

The check is carried out either when
the ignition is switched on using the oil level indicator on the instrument
panel, or using the dipstick.

Engine oil change

Refer to the ser vicing booklet for details of the
interval for this operation.
In order to maintain the reliabilit
y of the engine
and emission control system, the use of
additives in the engine oil is prohibited.

Oil specifi cation

The oil must be the correct grade for your engine and conform to the manufacturer's
recommendations.
After topping up the oil, the check whenswitching on the ignition with the oillevel indicator in the instrument panelis not valid during the 30 minutes after topping up.
If a level drops significantly, have the corresponding system checked by a CITRO
ËN dealer or a qualified workshop.
Check all of these levels regularly, in line with the ser vicing booklet and the requirements of the warranty. Top them up if necessary, unless other wise indicated.
This manual check will onl
y be correct if the
vehicle is on level ground and the engine has
been off for more than 30 minutes.
It is normal to top up the oil level between
two ser vices
(or oil changes). CITROËNrecommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms).

Coolant level
The coolant level should be closeto the "MA X" mark but should never exceed it.

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 shouldbe close to the "MA X" mark. With
the engine cold, unscrew the cap tocheck the level. Th
e brake fluid level should be close
to 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. When the en
gine is warm, the temperature of
the coolant is regulated by the fan. This can
operate with the ignition off.
For vehicles fitted with a
par ticle emissions
filter, the cooling fan may continue to
run after stopping the vehicle, even if theengine is cold.

231Checks
Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water.

Screenwash / headlamp
wash level
To check the level or top up the fluid on vehicle fitted with headlamp washers, immobilise the
vehicle and switch of the engine. )Before opening the bonnet, ensure that the engine has completely stopped. )Open the screenwash reser voir filler cap.
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful tohealth or indeed very corrosive.

Do not discard used oil or fluids into sewers or onto the ground.

Take used oil to a CITROËN dealer or a qualified workshop (France) or to anauthorised waste disposal site.
