PEUGEOT SERVICING
Your vehicle benefits from extended service intervals.
•For petrol engines: every 20,000 miles (30 000 km) or every two years.
• For direct injection diesel engines: every 12,000 miles (20 000 km) or every two years.
The extension of the service intervals means that the engi ne oil level must be checked regularly: topping up of the
oil between oil changes is normal.
It is for this reason, and for your complete peace of min d, that your Peugeot dealer will carry out a levels check and
topup midway between each routine service, at the time or distance intervals specified.
This will be undertaken free of charge, provided that the maintenance of your vehicle has been carried out within the
PEUGEOT network. At the same time, your Peugeot dealer will offer you a Peugeot safety check, for a nominal fee.
A Peugeot professional will carry out a quick check, and will top up the levels if necessary (oil up to 1 litre, coolant
and screen wash).
The date of the intermediate visit is not shown by the serv ice indicator.
It is to be carried out at least every 10,000 miles (15 0 00 km) for petrol engines and every 6,000 miles (10 000 km) for
direct injection diesel engines.
If the oil level is too low there is a risk of serious d amage to the engine: check the engine oil level at least every
2,000 miles (3 000 km) or 3,000 miles (5 000 km), depen ding on the conditions of use.
The extended service intervals have been made possible by technica l modifications to the vehicles and lubricants:
THUS IT IS ESSENTIALTO ONLY USE ENGINE LUBRICANTS WHICH ARE APPROVED AND REC OMMENDED BY THE
MANUFACTURER

The ESPsystem offers
increased safety during
normal driving, but should
not incite the driver to take
risks or to drive at high speed.
The operation of the system is
assured to the extent to which the
recommendations of the manufac
turer regarding the wheels (tyres
and wheel rims), the braking com
ponents, the electronic compo
nents and the assembly and repair
procedures within the PEUGEOT
network are respected.
After an accident or impact, have
the system checked by a
PEUGEOT dealer.

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and com
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act
ing 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.
If there is a variation between the tra
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle
back on course.
Operation of the ASR and ESP
systems
When one of these two sys
tems is operating, this light
flashes. Handbrake
Applying
When parking, pull the handbrake to
immobilise your vehicle.
W
arning: when parking on a slope,
direct your wheels towards the pave
ment and apply the handbrake.
Releasing
Pull the handle and press the button
to release the handbrake.
Disarming the ESP / ASR systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...),
it could prove useful to disarm the
ASR system to make the wheels
spin and regain grip. 
Press the switch "ESP OFF", sit
uated to the left of the steering
wheel.
The switch lights up and the indicator
lights come on, accompanied by the
message '' ASR/ESP deactivated''
on the multifunction display: the
ESP and ASR systems no longer
affect the operation of the engine or
the brakes.
They engage again: automatically when the ignition is
switched off,
 manually by pressing the switch
again.
Operating check When a system malfunction
occurs, the switch light
flashes and the indicator
light comes on.

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.
