Sport and Snow programmes In addition to the autoadaptive pro- gramme, two special programmes
are available. The indicator light cor-responding to the programme selec-ted lights up on the instrument panel. Sport programme Once the vehicle has been started and position Dselected, press the
S button.
The gearbox automatically favoursdynamic driving. Snow programme This programme makes starting easier
and offers smooth driving in conditions
when traction is poor.  Once the vehicle has been started and position Dselected, press the
button.
The gearbox adapts to driving onslippery roads.
Note : You can return to the autoadaptive
programme at any time.
 Press the Sor button again to
cancel the current programme. Operating anomaly Any disruption of the system is indi- cated by the alternate flashing of thesport and snow lights on the instru-ment panel. In such a case, the gearbox will operate in downgrade mode (locked
in 3rd gear). You may feel a substan-tial knock when reverse is selectedfrom position
Por N(this does not
damage the gearbox). Do not exceed 60 m.p.h. (100 km/h), if regulations permit this.
Contact a PEUGEOT dealer without
delay.

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.

CRUISE CONTROL Cruise control enables the vehicle to maintain a steady speed pro-
grammed by the driver, regardless ofthe road characteristics and withoutthe driver having to touch the accel-erator or brake pedals. In order for it to be memorised, the vehicle speed must be greater than25 m.p.h (40 km/h) or 40 m.p.h
(60 km/h), depending on the engine,and fourth gear at least must beengaged (second gear for the auto-matic gearbox). Operation 
Place switch 1in the ONposition.
A speed can be memorised. Place switch 1in the OFF position
to cancel.
Memorising a speedAs soon as you reach the chosen speed, press button 2or 3. This
memorises the speed, which will be
maintained automatically. Note:
It is possible to accelerate and drive
momentarily at a speed greater than the memorised speed. When the acceleratorpedal is released, the vehicle will return tothe memorised speed. Cancelling the memorised speed If you wish to cancel the memorised speed:  press button 4or the brake or
clutch pedal.
Recalling the memorised speedAfter cancellation, press button 4.
Your vehicle will return to the last memorised speed. Changing a memorised speed
To memorise a speed higher than the previous one:  press button 3;
 release it when you have reached the required speed.
To memorise a speed lower than theprevious one:  press button 2;
 release it when you have reached the required speed.
Cancelling the cruise control  Place switch 1in the OFF position
or switch off the ignition.
Do not use cruise control on slippery roads or in heavytraffic. THE ABS ANTI-LOCK BRAKINGSYSTEM When used with approved
tyres in good condition, the ABS increases the stability and manoeu-vrability of your vehicle, particularlyon poor or slippery road surfaces. The anti-lock braking system comes into operation automatically whenthere is a risk of wheel lock.
EMERGENCY BRAKING
ASSISTANCE SYSTEM
In an emergency, this system enables the optimum braking pres-
sure to be reached more quickly,thus reducing the stopping distance. It is triggered by the speed at which
the brake pedal is activated. The
effect of this is a reduction in theresistance of the pedal and an
increase in braking efficiency. The normal operation of the ABSmay make itself felt by slightvibrations of the brake pedal. In emergency braking, press very firmly without releasingthe pressure.

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.
