Air conditioning
QuestionAnswer
It seems to me that the vehicle runs less on electric
when the heating or air conditioning is operating, is
that right?
the
demand for heating or air conditioning may require the starting of the Diesel engine
until the desired level of comfort is attained.
Normal hybrid operation is simply put back.
t
h
e period can be longer under low or very high
ambient temperatures.
It seems to me that when it is very hot and the air
conditioning is working, the vehicle runs on electric for
shorter periods. Is that right? When it is hot, the periods when the Diesel engine 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
e
c
o OFF button (which brings the
vehicle out of Z
eV m

ode 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 "
to
wing" section).
th

is allows a jet ski or two-wheeler on a trailer to be towed, for example.
th

e "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 the
engine's cooling system.
Why 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.
th

is 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 cooling
system, comprising an air intake (located on
the rear shelf) and a fan (located behind the
b o ot t r im).
th
is system 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 may
overheat, damaging the battery and causing a
loss of per formance of the hybrid system. For the best use of the high voltage
battery, please follow these
recommendations:
-

d
o not obstruct the air intake with
loose articles, otherwise, the
battery may overheat, causing a
loss of per formance of the hybrid
system
-

d
o not spill fluids, as this may cause
damage to the battery.

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

Driving advice
Distribution of loads
F 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 by 10
% for every 1 000 metres of
altitude.
Side wind
F 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.
F
t
o l
ower the engine speed, reduce your
speed.
th

e 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.
F

I
f 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 a void overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
th

e rear parking sensors will be
deactivated automatically if a genuine
P
e

uge
Ot
towbar is used.
Refer to the "
te

chnical data" section for details
of the weights and towed loads which apply to
your vehicle.

Very cold climate screen
FittingRemoval
Removable protective screen which prevents the accumulation of snow at the radiator cooling fan.
Do not forget to remove the very cold
climate screen:
- when the ambient temperature exceeds
10° C (for example: in summer,
...),
- when towing,- at speeds above 75 mph (120 km/h).
F Offer up the screen to the front of the top section of the front bumper upper grille.
F

P

retaining clip in turn.
Before fitting or removing the screen,
ensure that the engine is off and the cooling
fan has stopped. It is recommended that
the screen be fitted and removed by a

Opening the bonnet
Opening
F From inside: pull the release lever, located
on the left below the dashboard, towards
you.
Before doing anything under the
bonnet, switch off the ignition (
Ready
lamp off) to avoid any risk of injury
resulting from automatic operation of
the engine.
Closing
F Lower the bonnet and release it at the end of its travel.
F

C
heck that it is latched correctly.
F

F
rom the outside
: lift the safety catch and
raise the bonnet.
A bonnet strut opens the bonnet and holds it
open.
Never touch, handle or remove the
orange "high voltage" cables.
th

e use of a high pressure jet wash
under the bonnet is strictly prohibited,
in order to avoid damage to the electric
components.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.

Checking levels
Before doing anything under the
bonnet, switch off the ignition (Ready
lamp off) to avoid any risk of injury
resulting from automatic operation of
the engine.
Engine oil level
the check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles with and electric oil
level gauge, or using the dipstick.
to e

nsure that the reading is correct,
your vehicle must be parked on a level
sur face and the engine having been off
for more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). P
e

uge
Ot

recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms). Check all of these levels regularly, in line with the warranty and maintenance record. t

If a level drops significantly, have the corresponding system checked by a P

dealer or a qualified workshop.
ta

ke care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Checking using the dipstick
Refer to the "Diesel engine" section for
the location of the dipstick in the engine
compartment of your vehicle.
F
t
a
ke the dipstick by its coloured grip and
remove it completely.
F

W

non-fluffy cloth.
F

R
efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between the marks A
and B .
A = MA X
B = MIN If you find that the level is above the A mark or
below the B mark, do not star t the engine
.
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
P
e

Ot
dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top up the engine oil.
Oil grade
Before topping-up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
