Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, taking a break every two
hours is strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, fallen leaves, etc.) – Risk of fire!Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P
, depending on
the type of gearbox.
In case of towing
If you are obliged to drive on a flooded road:
- c heck that the depth of water does not
exceed 15
cm, taking account of waves that
might be generated by other users,
-

d
eactivate the Stop & Start function,
-

d
rive as slowly as possible without stalling.
In all cases, do not exceed 6
mph (10 km/h),
-

d
o not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a PEUGEOT dealer or a qualified workshop. Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity
to 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 lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.

Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation advice
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face on the side
of the road.
F

A
pply the parking brake and, if necessary,
place a chock under a wheel to prevent
movement of your vehicle.

(50


km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened. It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging your vehicle's tyres and the
road sur face. If your vehicle is fitted with
alloy wheels, check that no part of the
chain or its fixings is in contact with the
wheel rim.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original tyre size Type of chain
195/65 R15 9
mm link
205/55 R16
2 2 5 /4 5 R17
225/40 R18 K-Summit K23
235/35 R19 Polar Grip 70
For more information, contact a PEUGEOT
dealer or a qualified workshop.
Very cold climate screen
Removable protective screen which prevents
the accumulation of snow at the radiator
cooling fan.
It is recommended that the screen be
fitted and removed by a PEUGEOT dealer
or a qualified workshop.
Before fitting or removing a screen,
ensure that the engine is off and the
cooling fan has stopped.
Fitting
F Position the screen in front of the top part of the upper grille in the front bumper.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by a PEUGEOT
dealer or a qualified workshop. The liquid must comply with the
manufacturer's recommendations and with
the vehicle's engine.
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).
Used products
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.
Take used oil to a PEUGEOT dealer or
a qualified workshop and dispose of it in
the containers reser ved for this purpose.
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 equipped with an electric
gauge, or using the dipstick.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped for more than
30


minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). PEUGEOT
recommends that you check the level, and top
up if necessary, every 3,000
miles (5,000 km).
Checking using the dipstick

When the engine is hot, the temperature of this
fluid is regulated by the fan.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the
engine before carrying out any work.
To avoid the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.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.
Screenwash fluid level
Top up to the required level when
necessary.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water. In wintry conditions, it is recommended
that you use an ethyl alcohol or methanol
based fluid.
Diesel fuel additive level
(Diesel with particle filter)
A low additive level is indicated by
illumination of this warning lamp,
accompanied by an audible warning
and a message in the instrument
panel screen.
To p p i n g u p
This additive must be topped up without delay
by a PEUGEOT dealer or a qualified workshop.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a PEUGEOT
dealer or a qualified workshop.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections
are clean.
For more information on the precautions
to take before starting work on the 12
V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a 12
V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a PEUGEOT dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary .

Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a PEUGEOT
dealer or a qualified workshop.
Weights and towed loads
The weights and towed loads relating to your
vehicle are given in the registration document,
as well as in sales brochures.
These values are also given on the
manufacturer's plate or label.
For more information, contact a PEUGEOT
dealer or a qualified workshop. The GTW (Gross Train Weight) and towed load
values indicated are valid up to a maximum
altitude of 1,000
metres. The towed load value
must be reduced by 10% for each additional
1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
High exterior temperatures may result
in a reduction in the per formance of the
vehicle to protect the engine. When the
exterior temperature is higher than 37°C,
limit the towed weight.
Towing by a lightly loaded vehicle can
adversely affect road holding.
Braking distances are increased when
towing a trailer.
When using a vehicle to tow, never
exceed a speed of approximately 62 mph
(100
km/h) (obser ve the local legislation
in force).
If the exterior temperature is high, it is
recommended that the engine is allowed
to idle for 1 to 2
minutes after the vehicle
comes to a stop, to facilitate its cooling.
