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
multi-function 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. 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.
To do this: place the lights stalk in the AUTO
position,
 place the key in the accessories position (first notch),
 press the end of the lights stalk formore than two seconds,
 place the lights stalk in the 0posi-
tion,
 flash the headlamps,
 get out of the car and lock it.

Handbrake Applying When parking, pull the handbrake to immobilise your vehicle.
Warning: 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 theASR system to make the wheelsspin and regain grip.
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 switch again. The ESP system offersincreased safety duringnormal driving, but shouldnot incite the driver to take
risks or to drive at high speed.The operation of the system isassured to the extent to which 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 respect-ed.After an accident or impact, havethe system checked by a
PEUGEOT dealer.
Operating check When a system malfunctionoccurs, the switch lightflashes and the indicatorlight comes on. Contact a
PEUGEOT dealer to check
the system.
TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP) These systems are linked and com-
plement the ABS system.
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 thereis a variation between the trajectoryfollowed by the vehicle and that
required by the driver, the ESP sys-tem automatically acts on the engineand the brake of one or morewheels, in order to put the vehicleback on course.
Operation of the ASR and ESP systems
When one of these two sys-tems is operating, this lightflashes.

CHECKING THE LEVELS Engine Checking the oil levelCheck 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 cold.There are two marks onthe 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 oilPrevent 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, theuse of additives in the engine oil isprohibited.
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, contact a PEUGEOT dealer imme-
diately.
Fluid change
- must be carried out according to the manufacturer's servicing sche- dule.
- 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 controlledby the engine fan. Because this fancan operate with the ignition keyremoved and because the coolingsystem is pressurised, wait for atleast one hour after the engine hasstopped before carrying out anywork. In the event of a breakdown and to avoid any risk of burns, slacken thecap to the first notch to release thepressure. When the pressure hasdropped, remove the cap and top upthe level.

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 (Ð) 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 (Ð) 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.
Wait 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 operatenormally following re-connection of the battery, you must re-initialise
it by turning the control to the maximum tilt position and pressing it for an exten- ded period.
- After every reconnection of the battery, switch on the ignition 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, 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 fit-
ted by a PEUGEOT dealer.
Your vehicle is basically designed fortransporting people and luggage but it
may also be used for towing a trailer.
Driving with a trailer subjects thetowing 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
Towing 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.Tyres Check the tyre pressures of the tow-
ing vehicle and of the trailer, observ-ing the recommended pressures. Braking
Towing increases the braking dis-tance. Lights Check the electrical signalling on the
trailer. Side wind
Take into acount the increased sen-sitivity to side wind.
