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 acce-lerator or brake pedals. In order for it to be memorised, the vehicle speed must be greater than40 km/h or 60 km/h , depending onthe engine, and fourth gear at leastmust be engaged (second gear forthe automatic gearbox). Operation Place switch 1in the ONposition.
A speed can be memorised. Place switch 1in the OFFposition
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 theaccelerator pedal is released, the vehi-cle will return to the 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 speed After 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.

THE ABS ANTI-LOCK BRAKING SYSTEM
When used with approved tyres in
good condition, the ABS increasesthe stability and manoeuvrability ofyour vehicle, particularly on poor orslippery 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.

FRONT AIR BAGS These are folded in the centre of the steering wheel for the driver and in
the fascia for the front passenger.
They are deployed simultaneously,except in cases where the air bag isdisarmed. Front air bag malfunctionIf this warning light comes on, accompanied by a buz-zer and the message "Air
bag fault" on the multi-
function display, contact a
PEUGEOT dealer to have the sys-tem checked.
AIR BAGS The air bags have been designed to maximise the safety of the occupantsin the event of serious collisions;they work in conjunction with theforce limiting seat belts. In the event of a serious collision, the electronic detectors record andanalyse any abrupt deceleration ofthe vehicle: if the triggering thresholdis reached, the air bags inflateinstantly and protect the occupantsof the vehicle. Immediately after the impact, the air
bags deflate rapidly, so that they donot hinder the visibility of the occu-pants nor their possible exit from thevehicle. The air bags will not be deployed in collisions which are not serious, for
which the seat belt is sufficient to
provide maximum protection. Theseriousness of the collision dependson the nature of the obstacle and thespeed of the vehicle at the momentof impact. Air bags only operate when the ignition is switched on. Note: the gas escaping from the air
bags can be a minor irritant.
DRIVING Y0UR 406 153
