ACCESSORIES
Towing a trailer

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.
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 9) and of
the trailer, observing the recommended
pressures.
We recommend the use of original
PEUGEOT towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted 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.
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 automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
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: the system only controls the vehicle,
not the trailer.

Rear parking
sensors
: the system does not
operate while the vehicle is towing.

Levels
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a PEUGEOT dealer
or consult the servicing booklet enclosed in
the handbook pack. To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.
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 failure which must be checked by
a PEUGEOT dealer as soon as possible.
If you have to remove/refit the engine
style cover, handle it with care to avoid
damaging the fixing clips.
Dipstick
There are two marks on
the dipstick:
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 at at
PEUGEOT dealer.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum 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.
Warning lamps
Checking by means of the warning
lamps on the instrument panel is
described in chapter 2, refer to the
"Instruments and controls" section.

A = maximum
If you fill past this mark,
contact a PEUGEOT
dealer.

B = minimum
Never allow the level to fall
below this mark.
Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 litre per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick.

CHECKS
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 failure which must be checked by
a PEUGEOT dealer 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.
Used oil
Avoid prolonged contact of used oil with the
skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground but
into the containers dedicated to this use at
PEUGEOT dealerships (France) or to an
authorised waste disposal site.
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.
Windscreen wash and headlamp wash level
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
Capacity of the reservoir: approximately
5.5 litres.

Checks
CHECKS
Air filter and passenger compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the "Under the
bonnet" section of chapter 7.
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule. To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet which
correspond to your vehicle's engine.
Only use products recommended by
PEUGEOT or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, PEUGEOT
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
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.
Bleeding the water contained in the Diesel filter
If this warning lamp comes on,
bleed the filter, otherwise bleed
regularly each time the engine oil
is changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a PEUGEOT dealer.
Battery
At the start of winter, have your battery
checked by a PEUGEOT dealer.
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 on the system, a drop
in the brake fluid level indicates that the
brake pads are worn.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
PEUGEOT dealer.
Oil filter
Change the filter regularly, in accordance
with the servicing schedule.

Fuel
Low fuel level
When the fuel tank level E
(Empty) is reached, this warning
lamp comes on. At this moment,
you have enough fuel left to
drive approximately 30 miles (50 km) ,
depending on the driving conditions, the
engine and the profile of the road. Fill up
without delay to avoid running out of fuel. The fuel tank must be filled
with the engine
off.
- Open the fuel filler flap.
- Support the cap with one hand.
- With the other hand, insert the key, then turn it anticlockwise.
- Remove the cap and hook it onto the clip located on the inside of the flap.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle. This could
cause malfunctions.
The capacity of the fuel tank is
approximately 90 litres.
- After filling the fuel tank, lock the cap and close the flap.
Fuel tanks of different capacities, 60 and
125 litres, may be fitted.
FUEL SYSTEM
CUT-OFF
In the event of a serious collision, a device
automatically cuts off the fuel supply to the
engine and the vehicle's electrical supply.
FILLING WITH FUEL
Check that there is no smell or leak of fuel
outside the vehicle.
Restore the supply by pressing:
- the first button, located under the glove box.
- the second button, located in the battery compartment under the driver's floor.
In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited
to low or minus temperatures.
