Hybrid system
Air conditioning
QuestionAnswer
It
seems to me that the vehicle runs less on electricwhen the heating or air conditioning is operating, is
that right? The demand for heatin
g or air conditioning may require the star ting of the Diesel engine until
the desired level of comfort is attained.
Normal hybrid operation is simply put back. The period can be higher under low or very high
ambient temperatures.
It seems to me that when it is ver
y hot and the air conditioning is working, the vehicle runs on electric for shor ter periods. Is that right? When it is hot, the periods when the Diesel en
gine is put on standby and the vehicle runs on electric are necessarily restricted in order to limit the difference between the temperature in
the vehicle and the level of comfort selected.
In very hot weather, it is always possible to press the Eco OFF button (which brings the
vehicle out of ZEV mode and prevents electric running or the stopping of the engine) to give
preference to temperature control (keeps the air conditioning running).
Special HYbrid4 features
Question Answer

Can I tow with my hybrid vehicle and how much? A HYbrid4 vehicle can tow between 500 kg and 800 kg (see the "Towing" section).
This allows a jet ski or two-wheeler on a trailer to be towed, for example.
The "technical" reason for the limit is related to maintaining adequate cooling capacity for
the internal combustion engine as well as the hybrid components that are also cooled by theengine's cooling system.
Wh
y does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the energy recovery by the electric motor.
This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of free energy.

Hybrid system







Fan cooling of the high voltage battery









The high voltage battery has an air coolingsystem, comprising an air intake (located on
the rear shelf) and a fan (located behind the
boot trim).

This s
ystem does not work continuously,
but adapts the force of the fan cooling to the
requirements of the battery.
Its operation can be heard at the rear, even if
the vehicle is stopped after a run.
If the air intake is blocked, the battery mayoverheat, damaging the battery and causing a
loss of performance of the hybrid system.
For the best use of the high voltage battery, please follow these recommendations: - do not obstruct the air intake with loose articles, otherwise, thebattery may overheat, causing a loss of performance of the hybrid system - do not spill fluids, as this may cause damage to the battery.

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 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

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 STOPwarning 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.

Checks






Checking levels






Before doing anything under the bonnet,
switch off the ignition (Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
Oil level

The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel, or using the dipstick.
Engine oil change
Refer to the ser vicing and warranty booklet for
details of the interval for this operation.
In order to maintain the reliabilit
y of the engineand 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'srecommendations.

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 and warranty booklet for
details of the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet the
DOT3 or DOT4 standard.

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. If a level drops si
gnificantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
Check all of these levels regularly, in line with the ser vicing booklet and the requirements of the warranties. Top them up if necessary, unless other wise indicated.
Ta k e c a r e w h e n w o r k i ng under the bonnet, as
cer tain areas of the engine may be extremelyhot (risk of burns) and the cooling fan couldstart at any time (even with the ignition off).

It will only 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). PEUGEOT recommends that youcheck the level, and top up if necessary, every 3 000 miles (5 000 kms).
After topping up the oil, the check when switching on
the ignition with the oil level indicator in the instrument
panel is not valid during the 30 minutes after topping up.

Checks
Coolant level
The coolant level should be close
to the "MAX" mark but should never exceed it.
In addition, as the cooling system is pressurised,
wait at least one hour a
fter switching off theengine before carrying out any work.
To avoid any risk of scalding, unscrew the cap
b
y two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top up t
he 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 levelis indicated by an audible signal and a message in the instrument panel screen. 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.
Top up the reser voir when you next stop the
vehicle.
