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 hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
th

e rear parking sensors will be
deactivated automatically if a genuine

For more information on weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.

Very cold climate screen
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 P

uge
Ot
dealer or
a qualified workshop.
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).
Removable protective screen which prevents the accumulation of snow at the radiator cooling fan.

A bonnet strut opens the bonnet and holds it
open.
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. Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing,


...) be limited.

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.
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

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 manufacturer's service schedule. t
o

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

dealer or a qualified workshop.
Checking using the dipstick

corresponding underbonnet layout view.

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

-

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.
Practical information

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.
Changing the coolant
the coolant does not have to be replaced at routine services.
Fluid specification
the coolant must conform to the
manufacturer's recommendations.
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.
Avoid prolonged contact of used oil or
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.
