Coolant temperature gauge
With the engine running, when the needle is:
- i n zone A , the temperature is correct,
-

i
n zone B, the temperature is too high;
the maximum temperature and the
central STOP warning lamps come on,
accompanied by an audible signal and a
warning message in the screen.
You MUST stop as soon as it is safe to do so.
Wait a few minutes before switching off
the


engine.
Contact a P

dealer or a qualified
workshop. After driving for a few minutes, the temperature
and pressure in the cooling system increase.

gauges and indicators
Service indicator
System which informs the driver when the
next service is due, in accordance with the
manufacturer’s servicing schedule.
More than 1 800 miles (3 000 km)
remain before the next service is due
When the ignition is switched on, no service
information appears in the screen.
th
e point at which the next service is due is
calculated from the last indicator zero reset,
depending on the distance travelled and the
time elapsed since the last service.
For BlueHDi Diesel versions, the degree of
deterioration of the engine oil is also taken into
account (depending on the country of sale).

When towing
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, 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 and the headlamp beam
height of your vehicle.

ensure that the engine is off and the cooling
fan has stopped. It is recommended that
the screen be fitted and removed by a

Checking levels
take 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).
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 so equipped, or
using the dipstick.Checking using the dipstick
the location of the dipstick is shown in the
corresponding underbonnet layout view.
F t

remove it completely.
F

W
ipe the end of the dipstick using a clean
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 .
Check all of these levels regularly, in line with the manufacturer's service schedule.

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

Ot
dealer or a qualified workshop.
A = MA X
to e

nsure that the reading is correct, your
vehicle must be parked on a level sur face
with

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). 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

dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top-up the engine oil.

Coolant level
the coolant level should be close
to the "MA X" mark but should never
exceed it.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the
engine before carrying out any work.
to a

void any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top-up the level.
It is normal to top-up the coolant
level between services (or coolant
replacements).
Fluid specification
the coolant must conform to the
manufacturer's recommendations. The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When the engine is warm, the temperature of
the coolant is regulated by the fan.
Fluid specification
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 and
a message in the instrument panel
screen.

fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.

Starting using another battery
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery
b o o s t e r.
First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
th
e two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, ...).

not pass close to moving parts of the
engine (cooling fan, belts, ...).
