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 service indicator informs you when each service is due; the point at which it is due is calculated from the last indicator zero reset (see corresponding section). This point is determined by two parameters: - the distance travelled,- the time elapsed since the last service. Note:the distance remaining may be weighted by the time factor, in accordance with the driver's style of driving.
The extension of the service intervals means that the engine oil level must be checked regularly: topping up of the oil between oil changes is normal. It is for this reason that the PEUGEOT network invites you to an intermediate visit between regular services.
The date of this service is not shown by the service indicator. It is to be carried out at least every 10,000 miles (15 000 km) for petrol engines and every 6,000 miles (10 000 km) for direct injection diesel engines.
A PEUGEOT dealer will carry out a quick check, and will top up the levels if necessary (oil, coolant, screenwash up to 2 litres). If the oil level is too low there is a risk of serious damage to the engine: check the engine oil level at least every 2,000 miles (3 000 km) or 3,000 miles (5 000 km), depending on the conditions of use The extended service intervals have been made possible by technical modifications to the vehicles and lubricants:
THUS IT IS ESSENTIAL TO ONLY USE LUBRICANTS WHICH ARE SUITED TO YOUR ENGINE AND RECOMMENDED BY
THE MANUFACTURER (see pages on "Lubricants").

AUTOMATIC SWITCHING ON OF THE LIGHTS The side lights and dipped beam headlamps switch on automatically if
the light is poor, or during continuousoperation of the windscreen wipers.
They switch off as soon as the lightbecomes bright enough or the wind-screen wipers stop. This function is active when the vehi-
cle is supplied to the customer.
To disarm or activate the function: Place the key in the accessories position (1st notch),
 Press the end of the lights stalkfor more than two seconds.
Note: in foggy weather, the bright-
ness sensor can detect sufficientlight. Because of this, the lights do
not come on automatically. Do not cover the brightness sen-
sor connected to the rain sensor,located on the windscreen behind
the mirror. It is used for automat-ic switching on of the lights. Operating check Activation Activation of this function is accom- panied by an audible signal and themessage
"Automatic lighting of
the headlamps activated" on the
multi-function display. Note: Manual operation of the lights
stalk always takes priority Disarming Disarming of the function is accom- panied by an audible signal and themessage "Automatic lighting of
the headlamps deactivated" on the
multi-function display. When driving, if this function is
switched off when the headlampswould switch on in automatic mode,the lights remain on. It is howeverpossible to disarm this function and
switch off the lights by:
Ð manually switching off the lights using the lights stalk,
Ð switching off the engine. If the brightness sensor does not
function correctly,
the system acti-
vates the function (the lights come
on). The driver is alerted by theflashing of the ''dipped beam'' warn-ing light on the instrument panel.
Contact a PEUGEOT dealer to have the system checked. Follow me Home When there is a low level of bright- ness or at night, if you leave yourvehicle, the side lights and thedipped beam lights may remain onfor approximately one minute. This function can only be used if the automatic switching on of the lightsmode is activated then:  with the key in the accessories position (1st notch), flash theheadlamps,
 get out of the car and lock it.

THE HANDBRAKE
To apply When parking on a slope, turn the wheels towards the kerb and applythe handbrake.
To release Pull the handle and press the button to release the handbrake and movethe vehicle.
Disarming the ESP/ASR systems In certain exceptional conditions
(vehicle stuck in mud or snow, or onloose ground...), it could prove useful
to disarm the ASR and ESP systemsto make the wheels spin and regaingrip. 
Press the switch "ESP OFF", sit-
uated to the left of the steering wheel.
The switch lights up and the indicatorlights come on, accompanied by themessage '' ASR/ESP de-activated''
on the multi-function display: the
ESP and ASR systems no longer
affect the operation of the engine orthe brakes. They engage again: automatically when the ignition is
switched off,
 manually by pressing the switchagain. The ASR/ESP systemsoffer increased safety dur-ing normal driving, butshould not incite the driver
to take risks or to drive at highspeed. The operation of these systems is assured on condition that therecommendations of the manufac-turer regarding the wheels (tyresand wheel rims), the braking com-ponents, the electronic compo-nents and the assembly andrepair procedures within thePEUGEOT network are respected. After an accident or impact, have the system checked by a
PEUGEOT dealer.
Operating check When a system malfunctionoccurs, the switch lightflashes and the indicatorlight comes on.
Contact a PEUGEOT dealer tocheck the system.
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 wheelsand on the engine. It also allows thedirectional stability of the vehicle tobe improved on acceleration. If there is a variation between the tra- jectory followed by the vehicle and
that required by the driver, the ESPsystem automatically acts on theengine and the brake of one or morewheels, in order to put the vehicleback on course.
Operation of the ASR and ESP systems
The warning light flashes if
the ASR or ESP is activated.

CHECKING THE LEVELS 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 coldusing the oil gauge or the dipstick.Dipstick There are two marks on the dipstick: A=maximum
Never fill past this mark. B= minimum
To maintain the reliability of the engines and of theemission control sys-tems, the use of additivesin the engine oil is prohib-ited.
Oil change According to the information given in
"PEUGEOT SERVICING" .
Note: avoid any prolonged contact of
used oil with the skin.
Viscosity selection In all cases, the oil selected must meet the manufacturer's require-ments.

Brake and clutch fluid level:
- The level should always bebetween the DANGER and MAX
marks on the reservoir.
- If the level drops substantially, con- tact a PEUGEOT dealer immedi-
ately.
Fluid change:
- must be carried out according to the manufacturer's servicing schedule.
- use fluids recommended by the manufacturer, which fulfil DOT 4standards.
Note: the brake fluid is noxious and
very corrosive. Avoid any contactwith the skin. Coolant level Use the fluid recommended by the
manufacturer. When the engine is warm, the tem- perature of the coolant is controlledby the engine fan. Because this fan
can operate with the ignition off andbecause the cooling system is pres-surised, wait for at least one hourafter the engine has stopped beforecarrying out any work.
To avoid any risk of burns, slacken the cap to the first notch to releasethe pressure. When the pressure hasdropped, remove the cap and top upthe level. Used products Do not dispose of used oil, brake fluid or coolant down drains or on theground. Power steering fluid level Open the reservoir with the engine
cold at ambient temperature. Thelevel should always be above theMIN mark, close to the MAX mark.
Windscreen and headlamp* wash fluid level For best quality cleaning and for your
safety, we advise that you useproducts recommended by
PEUGEOT.
* According to destination.
