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 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 each regular service.
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 dealerwill 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 ENGINE LUBRICANTS WHICH ARE APPROVED AND RECOMMENDED BY THE
MANUFACTURER.

AUTOMATIC SWITCHING ON OF THE LIGHTS Side lights and dipped beam head- lamps 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 in the windscreen behind
the mirror. It is used for automaticswitching 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
multifunction display. Note: Always operate the lighting
controls manually where this is pos- sible. Disarming Disarming of the function is accom- panied by an audible signal and themessage "Automatic lighting of
the headlamps deactivated" on the
multifunction display. When driving, if this function is
switched off when the headlampswould switch on in automatic mode,the lights remain on. It is however possible to disarm this
function and switch off the lights by: - manually switching off the lights using the lights stalk,
- switching off the engine. If the brightness sensor does not
function correctly,
the system acti-
vates the function (the lights comeon). The driver is alerted by the flashingof the ''dipped beam'' warning lighton 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.

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. Ifthere 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.

CHECKING THE LEVELS Oil level Check the level regularly and top up between changes. Maximumconsumption is 0.5 litres per 600miles (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 the emission control sys-tems, the use of additivesin the engine oil is prohi-bited.
Oil change According to the indications of the
"PEUGEOT SERVICES" .
Note: avoid any prolonged contact of
used oil with the skin. V iscosity selection
In all cases, the oil selected must meet the manufacturer's require-ments.

Brakes and clutch level: -The level should always be bet- ween the DANGER and MAX
marks on the reservoir.
- If the level drops substantially,
contact a PEUGEOT dealer imme-
diately.
Fluid change - must be carried out according to the manufacturer's servicing sche-dule.
- 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 release the 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. The level should always beabove the MINI mark, close to theMAXI mark. W

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 them.
To start the vehicle from another battery:
- Connect the red cable to the positive (+) terminals of the two batteries,
- Connect one end of the green or black cable to the negative (-) terminal of the
slave battery,
- Connect the other end of the green or black cable to an earth point on the bro-
ken down vehicle, as far as possible from the battery,
Operate the starter, let the engine run. W ait for the engine to return to idle, then disconnect the cables.
-Never disconnect a terminal when the engine is running.
- Never charge a battery without first disconnecting the terminals.
- Close the sunroof before disconnecting the battery. If it does not opera-
te normally following re-connection of the battery, you must re-initialise it by turning the control to the maximum tilt position and pressing it for a fewseconds.
- After every reconnection of the battery, switch on the ignition and wait 1minute 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, warninglights, courtesy lights, electric win-
dows, wipers etc.) will switch offautomatically to avoid draining the
battery. Once the electrical equipment goes into economy mode, it is necessaryto start the engine to enable theequipment to work again.

TOWING A TRAILER,
CARAVAN, BOAT etc.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage of
your vehicle. The tow bar must be
fitted by a PEUGEOT dealer. Y our vehicle is primarily 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 significantstress and its driver must be particu-larly careful. Air density decreases with altitude, thus reducing engine performance.Above 1000 metres, the maximumtowing load must be reduced by 10%and so on for every 1000 metres ofaltitude. Driving advice Distribution of loads:Distribute the load in the trailer so that the heaviest items are as closeas possible to the axle and the noseweight approaches the maximumpermitted without exceeding it. Cooling: T
owing a trailer on a slope increases
the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependenton the engine speed.
On the contrary, use a high gear to lower the engine speed, and reduceyour speed. The maximum towing load on a long slope depends on the gradient andthe outside temperature. In all cases, pay attention to the coolant temperature. If the warning light comes on, stop
the vehicle and switch off the engineas soon as possible. T
yres:
Check the tyre pressures of the tow-
ing vehicle and of the trailer, observ-ing the recommended pressures. Braking: T owing increases the braking dis-
tance. Lights: Check the electrical signalling on the
trailer. Side wind: T ake into acount the increased sen-
sitivity to side wind.
