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 vehicle
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:
Ð manually switching off the lights using the lights stalk,
Ð switching off the engine.

When the engine is idling, with the brakes not ap-plied, if function R,D, 3, 2
or 1is selected, the ve-
hicle will move even if you are notaccelerating. For this reason, do not leave
children unsupervised inside the vehicle, when the engine isrunning. When maintenance operations need to be carried out with theengine running, apply the hand-brake and select function P.
Never select function Nwhen the
vehicle is moving. Never select functions Por R
unless the vehicle is stationary.Do not change from one position to another to improve braking effi-ciency on a slippery surface.
With the selector lever in position P , it will be impossible to change

The ESP system offers increased safety duringnormal driving, but shouldnot incite the driver to take
risks or to drive at high speed. The operation of the system is assured 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 and repairprocedures within the PEUGEOTnetwork are respected. After an accident or impact, have the system checked by a
PEUGEOT dealer.

TRACTION CONTROL (ASR) AND
DYNAMIC STABILITY CONTROL
CONTROL (ESP) These systems are linked and com-
plement the ABS.
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. 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
When one of these two sys-tems is operating, this lightflashes. Handbrake Applying When parking, pull the handbrake toimmobilise 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 buttonto 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", si-
tuated 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.
Operating check When a system malfunctionoccurs, the switch lightflashes and the indicatorlight comes on.
Contact a PEUGEOT dealer tocheck the system.

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, thevehicle speed must be greater than
25 mph (40 km/h) or 37 mph (60 km/h),depending on the engine, and fourthgear at least must be engaged (secondgear for the 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 greaterthan the memorised speed. When theaccelerator pedal is released, the vehiclewill return to the memorised speed.
Cancelling the memorisedspeed 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.
Cancelling the cruise control  Place switch 1in the OFFposition
or switch off the ignition.

Do not use cruise control on slippery roads or inheavy traffic.
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.
