CHECKING THE LEVELS
Engine
Checking the oil level
Check the level regularly and top up
between changes. Maximum con
sumption is 0.5 litres per 600 miles
(1 000 km).
The oil level should be checked with
the vehicle level and the engine cold.There are two marks on
the dipstick:
A= maximum
B = minimum
Oil change: according to the manu
facturer's servicing schedule.
Dipstick. Never fill past the maxi mum mark A.
Oil level gauge on the instrument panel.
Viscosity selection
In all cases, the oil selected must
meet the manufacturer's require
ments.

Oil filter
Change the filter regularly according
to the servicing schedule.
Used oil
Prevent used oil from coming into
prolonged contact with the skin.
Do not dispose of used oil into drains
or onto the ground.
To maintain the reliability of engines
and emission control systems, the
use of additives in the engine oil is
prohibited.
Brakes and clutch
Checking the brake and clutch
fluid level:
The level should always be above
the DANGER mark on the reser
voir.
If the level drops substantially, con tact a PEUGEOT dealer imme
diately.
Fluid change
must be carried out according to the manufacturer's servicing
schedule.
use fluids approved by the manu facturer, which fulfil DOT 4 stan
dards. Cooling system
Use the fluid approved by the manu
facturer.
When the engine is warm, the tem
perature of the coolant is controlled
by the engine fan. Because 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.
In the event of a breakdown and to
avoid any risk of burns, slacken the
cap to the first notch to release the
pressure. When the pressure has
dropped, remove the cap and top up
the level.

Only use products
approved by Automobiles
PEUGEOT.
To ensure best perfor
mance from components as
important as the power steering
and the braking system,
PEUGEOT selects and offers
quite specific products.
Power steering reservoir
Open the reservoir with the engine
cold. The level should always be
above the MINI mark, close to the
MAXI mark.
Windscreen and headlamp
wash reservoir
For best quality cleaning and for your
safety, we recommend that you use
products approved by PEUGEOT
(capacity 4.5 litres or 9 litres with
headlamp wash).
Battery
At the start of winter, have your bat
tery checked by a PEUGEOT dealer.
Air filter
Regular replacement of the filter ele
ment is essential. If you drive in
very dusty conditions, change it
twice as often. Brake pads
Brake pad wear depends on the
style of driving, in particular for vehi
cles that are used in town, for short
journeys. It may be necessary to
check the thickness of the pads even
between services.
Handbrake
Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
PEUGEOT dealer.
Manual gearbox
This does not need an oil change.
Check the level according to the
manufacturer's servicing schedule.
Automatic autoadaptive
gearbox
This does not need an oil change.
Have the level checked by a
PEUGEOT dealer according to the
manufacturer's servicing schedule.

BATTERY
To charge the battery using a battery charger:
Disconnect the battery,
Follow the instructions for use given by the battery charger manufacturer,
Reconnect starting with the negative (–) terminal,
Check that the terminals and connectors are clean. If they are covered with sul
phate (white or greenish deposit), disconnect them and clean t hem.
To start the vehicle from another battery:
Connect the red cable to the positive (+) terminals of the tw o batteries,
Connect one end of the green or black cable to the negat ive (–) terminal of the
slave battery,
Connect the other end of the green or black cable to an e arth point on the bro
ken down vehicle, as far as possible from the battery,
Operate the starter, let the engine run.
Wait for the engine to return to idle, then disconnect th e cables.
Never disconnect a terminal when the engine is running.
Never charge a battery without first disconnecting the terminal s.
Close the sunroof before disconnecting the battery. If it does not
operate normally following reconnection of the battery, you must
reinitialise it by turning the control to the maximum tilt po sition and pressing
it for a few seconds.
After every reconnection of the battery, switch on the igniti on and wait
1 minute before starting to allow the electronic systems to be initialised. If
slight difficulties are experienced after this, please contact a PEUGEOT
dealer. It is advisable to disconnect the battery if the vehicle
is not to be used for a period of more than one month.Economy mode
With the engine switched off and the
ignition key in the "running" or
"accessories" position for about half
an hour, certain electrical equipment
(displays, instrument panel, warning
lights, courtesy lights, electric win
dows, wipers etc.) will switch off
automatically to avoid draining the
battery.
Once the electrical equipment goes
into economy mode, it is necessary
to start the engine to enable the
equipment to work again.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow
bars that have been tested and
approved from the design stage of
your vehicle.
The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically designed for
transporting people and luggage but
it may also be used for towing a
trailer.
Driving with a trailer subjects the
towing vehicle to more significant
stress and its driver must be particu
larly careful.
Air density decreases with altitude,
thus reducing engine performance.
The maximum towing load must
be reduced by 10% for every
1000 metres of altitude.
Driving advice
Distribution of loads:
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. 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.
On the contrary, use a high gear to
lower the engine speed, and reduce
your speed.
The maximum towing speed on a
long slope depends on the gradient
and the outside temperature.
For vehicles fitted with a direct injec
tion petrol engine, after towing or dri
ving at high speed for a long period
of time, the fan may operate for
approximately 6 minutes.
In all cases, pay attention to the
coolant temperature.
If the warning light comes on, stop
the vehicle and switch off the engine
as soon as possible.
Tyres:
Check the tyre pressures of the tow
ing vehicle and the trailer, observing
the recommended pressures.
Brakes:
Towing increases the braking distance.
Lights:
Check the electrical signalling on the
trailer.
Side wind:
Take into acount the increased sen
sitivity to side wind.
