The ASR system optimises drive to prevent the wheels skidding, byacting on the brakes of the drivewheels and on the engine. It alsoallows the directional stability ofthe vehicle to be improved onacceleration.
Operation of the ASR systemWhen this system is operat- ing, this light flashes.
TRACTION CONTROL (ASR) This system is linked with and com-
plements the ABS. Disarming the ASR system In exceptional conditions (starting the vehicle when stuck in mud, on
snow, on unstable ground...), it may
prove useful to disarm the ASR sys-tem to allow the wheels to skid andregain grip. 
Press switch Ain the centre of
the fascia panel.
The indicator light on the switch and the warning light
come on: the ASR system willno longer act on the operationof the engine or the brakes. It will come into operation again: 
automatically above 20 mph (30 km/h),
 manually when the switch ispressed again.
Operating check When a malfunction of thesystem occurs, the warninglight on the instrument panelcomes on.
Contact a PEUGEOT dealerto have the system checked.

Normal operation of the ABS may make itself felt by slight vibrationsof the brake pedal. In emergency braking, press very firmly without releasingthe pressure.
The operation of the sys- tem is ensured to theextent to which the rec-ommendations of themanufacturer regarding
the wheels (tyres and wheel rims),the braking components, the elec-tronic components and the assem-bly and repair procedures withinthe PEUGEOT network areobserved. After an impact, have the system
checked by a PEUGEOT dealer.
Illumination of this warning light indicates a malfunctionof the electronic brake forcedistribution, which cancause a loss of control of
the vehicle when braking.
Stop immediately.

CHECKING THE LEVELS Oil level Check the level regularly and top
up between changes. The maxi-mum consumption is 0.5 l per
600 miles (1 000 km). Check the level with the vehicle level, engine cold, using the oillevel gauge on the instrumentpanel or the dipstick.
Dipstick
There are two marks onthe dipstick: A=maximum
Never fill past this mark.B= minimum
To maintain the reliability of engines and emissioncontrol systems, the useof additives in engine oilis prohibited.
Oil change According to the information given in
"PEUGEOT SERVICING" .
Note: avoid used oil coming into
prolonged contact with the skin.
Viscosity selection In all cases, the oil selected must meet the manufacturer's require-ments. Brake fluid level:
Ð The level must always be between the DANGER and MAXIMUM
marks in the reservoir.
Ð If the level drops substantially, contact a PEUGEOT dealer
immediately.
Fluid change:
Ð must be carried out according to the manufacturer's servicing schedule.
Ð use fluids recommended by the manufacturer, which fulfil DOT4standards.
Note: brake fluid is harmful to health
and very corrosive. Avoid all contactwith the skin. Cooling system Use the fluid recommended by the
manufacturer. When the engine is warm, the tem- perature of the coolant is controlled
by the engine fan. As this fan canoperate with the ignition keyremoved and because the coolingsystem is pressurised, wait for atleast one hour after the engine hasstopped before carrying out anywork. Slacken the cap to the first notch torelease the pressure to prevent anyrisk of scalding. When the pressurehas dropped, remove the cap andtop up the level. Note:
the coolant does not need to
be changed. Used oil Do not dispose of used oil, brake fluid or coolant into drains or into theground. Power steering reservoir  Open the reservoir, with the engine at ambient temperature.The level should always beabove the MIN. mark and closeto the MAX. mark.
Windscreen and headlamp* wash level For best quality cleaning and for your
safety, we would advise that you use
products recommended by PEUGEOT.
* According to destination.

To ensure best perform- ance from components as
important as the power steering andthe braking system, PEUGEOTselects and offers quite specificproducts.
CHECKS Battery
At the start of winter, have your bat-
tery checked by a PEUGEOT dealer. Air filter and passenger compartment filter Have the filter elements replaced
regularly. If you drive in dusty con-
ditions, change them twice asoften. Brake pads Brake pad wear depends on the style of driving, in particular for vehi-cles which are used in town, overshort distances. It may be necessary to check the thickness of the pads, even betweenservices. Handbrake Where the handbrake travel is too great or there is a reduction in theperformance of the system, thehandbrake should be adjusted, evenbetween services. Have the system checked by a
PEUGEOT dealer. Oil filter
Change the filter regularly, in accor- dance with the servicing schedule.
Fuel supply cut-off In a serious collision, a system pre- vents fuel from reaching the engine.
To re-establish the fuel supply, press the switch on the angle of the front
left-hand suspension assembly,under the bonnet.

BATTERY
To charge the battery using a battery charger:
Ð Disconnect the battery,
Ð Follow the instructions for use given by the battery charger manufacturer,
Ð Reconnect starting with the negative (Ð) terminal,
Ð 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:
Ð Connect the red cable to the positive (+) terminals of the two batteries,
Ð Connect one end of the green or black cable to the negative (Ð) terminal of the slave battery,
Ð 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.
Ð Never disconnect a ter- minal when the engine is running.
Ð Never charge a battery without first disconnecting the terminals.
Ð After every reconnection of the battery, switch on the ignition andwait 1 minute before starting toallow the electronic systems to beinitialised. If slight difficulties areexperienced 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.

TOWING A TRAILER,
CARAVAN, BOAT etc.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage ofyour vehicle. The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is primarily designed for transporting people and luggage butit 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 1 000 metres, the maximum
towing load must be reduced by 10 %
and so on for every 1 000 metres ofaltitude.Driving advice Distribution of loads:
Distribute the
load in the trailer so that the heaviest items are as close as possible to theaxle and the nose weight approachesthe maximum permitted withoutexceeding 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 towing vehicle and of the
trailer, observing the recommendedpressures. Braking: Towing increases the
braking distance. Lights: Check the electrical signal-
ling on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.

Filling the LPG/CNG tank (Capacity of approximately 60 litres for the LPG and 160 litres for theCNG)
Ð switch off the ignition,
Ð unscrew the cap protecting the filleropening, turning it anticlockwise,
Ð lock the filler nozzle onto the opening (if necessary, screw the appropriate adapter* onto the filleropening first),
Ð push the button on the pump,
Ð once filling has stopped automati- cally, unlock the filler nozzle,
Ð screw the protective cap back onto the filler opening, turning it clock- wise.
* According to destination. Petrol gauge When the low petrol level indicator comes on, fill the tank without delayas the engine can only start usingpetrol. Furthermore, a low petrol levelmay result in fuel circuit faults. LPG/CNG gauge The LPG/CNG level in the tank is represented by a group
4, consisting
of four green indicator lights and a redindicator light. This red indicator light comes on to indicate use of the LPG/CNG reservewhich provides you with a range of
approximately 25 miles (40 km) .
If the outside temperature is high, theLPG/CNG gauge may indicate aslightly higher quantity of gas than theactual level.
