Good practice
To avoid any risk of poisoning or
asphyxiation, the heater must not be used,
even
for short periods, in an enclosed space
such as a garage or workshop which is not
fitted with an exhaust
gas extraction system.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
th
ere is a risk of fire. The temperature near the heater must not
exceed 120 °C. A temperature higher than
this
(for example in the case of painting in
an oven
) could damage the components of
th
e electronic circuits.
The heater is supplied b
y the vehicle's fuel
tank. Ensure that the low
fuel warning lamp
i
s not on.
ADDITIONAL HEATING


Coolant circuit heater
This is an additional and separate s
ystem
which heats the Diesel en
gine hot coolant
loop to make starting easier.
It improves the demistin
g and defrosting
performance. Vehicles fitted with an HDi
engine may be fitted with a heater. When
t
he engine is at idle or the vehicle is
stationary, it is normal to notice a high-
pitched whistling noise and a slight emission
of smoke and odour.

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration. acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.

Deactivating the ASR/ESP systems

In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR and ESP systems to
make the wheels spin and regain grip.


- Press the button, located on the centre
console.

- The indicator lamp comes on: the ASR
and ESP systems no longer act.
Operating check

Good practice

The ASR/ESP systems offer increased
safety during normal driving, but should not
encourage the driver to take risks or to drive
at high speed.
The operation of these systems is assured
only if the recommendations of the
manufacturer regarding the wheels (tyres
and rims), the braking components, the
electronic components and fitting and repair
procedures are observed.
After an impact, have these systems
checked by a PEUGEOT dealer or a
qualified workshop.
Use the ESP to hold your course without
attempting to countersteer.
If there is a variation between the trajectory
followed by the vehicle and that required
by the driver, the ESP system automatically

Operation of the ASR and ESP
systems
The LED flashes when the ASR or
ESP is triggered.

They engage again:


- automatically above 30 mph (50 km/h),

- manually by pressing the button again.
When a malfunction of the
systems occurs, the warning lamp
comes on, accompanied by an
audible signal and a message in
the screen.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
The warning lamp may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.

Towing a trailer
For more information about weights,
refer to the administrative documents
(V5 registration document, ...) or to the
"Weights" section of chapter 8.
TOWING A TRAILER, CARAVAN, BOAT, ETC...


Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it.
Cooling
Towing a trailer on a slope increases
the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.

Driving advice

A towed vehicle must free wheel: gearbox in
neutral.

On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.

Tyres:
check the tyre pressures of the towing
vehicle (see the "Identification markings"
section of chapter 8) and of the trailer,
observing the recommended pressures.
Towbar

We recommend the use of genuine
PEUGEOT towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle, and that
you entrust the fitting of this equipment to a
PEUGEOT dealer.
If this equipment is not fitted by a PEUGEOT
dealer, it is imperative that it is fitted using
the electrical pre-equipment installed at the
rear of the vehicle and in accordance with
the manufacturer's instructions.
In accordance with the general instructions
a reminder of which has been given above,
we draw your attention to the risk associated
with fitting a towbar or electrical accessory
not recommended by PEUGEOT. Fitting
such equipment could result in the failure
of your vehicle's electronic system. Please
obtain information from the Manufacturer
before fitting this type of equipment.
See the "Levels" section of chapter 6.

Good Practice

In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the air conditioning is automatically
cut off to save engine power.
If the coolant temperature warning
lamp comes on, stop the vehicle
and switch off the engine as soon
as possible.
Brakes
Towing increases the braking distance. Drive
at a moderate speed, change down early
and brake gradually.

Side wind
Sensitivity to side wind is increased. Drive
smoothly and at a moderate speed.

ABS/ESP
The ABS or ESP systems only control the
vehicle, not the trailer or caravan.

Rear parking sensors
The parking sensors system does not
function while the vehicle is towing.

Changing the brake fluid

The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIN and
MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
PEUGEOT dealer or a qualified workshop as
soon as possible.


Warning lamps

These regular maintenance operations
will keep your vehicle in good running
order. Consult the instructions at PEUGEOT
dealerships or in the servicing booklet
enclosed in the handbook pack.
If you have to remove/refit the engine
style cover, handle it with care to avoid
damaging the fixing clips.

Oil level

Check the level regularly and top up
between changes.
Check the level with the vehicle level,
engine cold, using the dipstick.

Dipstick
There are two marks on the
dipstick:
A = maximum
If you fill past this mark,
contact a PEUGEOT
dealer or a qualified
workshop.
B = minimum
Never allow the level to fall
below this mark.
To maintain the reliability
of engines and emission
Oil change

It is imperative that this is carried out at the
intervals specified and the viscosity grade of
the oil selected must fulfil the requirements
in accordance with the manufacturer's
servicing schedule. Ask for advice from a
PEUGEOT dealer.
Remove the dipstick before filling.
For the 2 litre HDi engine, use the funnel
supplied when filling via the sump opening.
Check the level after filling (never exceed
the max mark).
Screw the cap back onto the sump before
closing the bonnet.

Viscosity selection
In all cases, the oil selected must meet the
manufacturer's requirements.

Levels



Cooling system

Only use the fluid recommended by the
manufacturer.
Otherwise, you risk seriously damaging your
engine.
When the engine is warm, the temperature
of the coolant is controlled by the engine
fan. As this fan can operate with the ignition
key removed and because the cooling
system is pressurised, wait for at least one
hour after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
PEUGEOT dealer or a qualified workshop as
soon as possible.

Power steering fluid level

The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MIN and
MAX marks. When this occurs with the engine running it
is due to the start of saturation of the particle
emission filter (exceptionally prolonged
urban type driving conditions: low speed,
long traffic jams, ...).
In order to regenerate the filter, you are
advised to drive at a speed higher than
40 mph (60 km/h) for at least five minutes
as soon as possible, when traffic conditions
permit (until the message disappears and
the service warning lamp goes off).
During regeneration of the particle emission
filter, relay noise may be heard under the
dashboard.
If the message is still displayed and if the
service warning lamp remains on, contact a
PEUGEOT dealer or a qualified workshop.

Topping up
The level must be between the MIN and
MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
PEUGEOT dealer or a qualified workshop.



Screenwash and headlamp wash
level
For best quality cleaning and for your safety,
we would advise that you use products of
the PEUGEOT range.
Capacity of the screenwash reservoir:
approximately 4.5 litres.
If your vehicle is fitted with headlamp
washers, the capacity of the reservoir is
7.5 litres.
To ensure optimum cleaning and prevent
freezing, this fluid must not be topped up or
replaced with plain water.


Diesel additive level (Diesel
with particle emission filter)
The minimum level of this additive
is indicated by lighting of the
service warning light, accompanied by an
audible signal and a message in the screen.
Topping up
This additive must be topped up by a
PEUGEOT dealer or a qualified workshop
without delay.

CHECKS


Battery

At the start of winter, have your battery
checked by a PEUGEOT dealer or a
qualified workshop.


Brake pads

Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak in the system, a drop
in the brake fluid level indicates that the
brake pads are worn.


Brake disc/drum wear

For any information on checking the brake
disc/drum wear, contact a PEUGEOT dealer
or a qualified workshop.


Parking brake

Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a PEUGEOT
dealer or a qualified workshop.


Oil filter

Change the filter regularly, in accordance
with the servicing schedule.


Carbon filter and passenger
compartment filter
The carbon filter permits continuous and
effective filtering of dust.
If the passenger compartment filter becomes
clogged, this may reduce the performance
of the air conditioning system and generate
unpleasant odours.
We recommend the use of a combined
passenger compartment filter. By means of
its second special active filter, it contributes
to the purification of the air breathed by
the occupants and the cleanness of the
passenger compartment (reduction of
allergic symptoms, unpleasant odours and
greasy deposits).
Refer to the servicing booklet to find out the
replacement interval for these components.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.

Particle emission filter (Diesel)

This filter actively contributes
to the preservation of air quality
by trapping unburnt polluting
particles. It is controlled
completely and automatically by the engine
management system.
This warning lamp comes on if there is a risk
of blockage of the filter.
This alert signals the start of saturation of
the particle emissions filter (exceptionally
prolonged driving in urban conditions:
reduced speed, traffic jams…).
If this alert persists, contact a PEUGEOT
dealer or a qualified workshop.
On acceleration after the vehicle has been
running for a prolonged period at very low
speed or at idle, you may, in exceptional
circumstances, notice the emission of water
vapour at the exhaust. This water vapour
does not have any adverse effect on vehicle
handling or the environment.
To regenerate the filter, it is recommended
that as soon as driving conditions permit,
you drive at a speed of at least 36 mph
(60 km/h) for at least 5 minutes (until the
warning lamp goes off and/or the message
disappears). Refer to "Under the bonnet" in section 6.
