THE KEYS The keys allow you to switch on the ignition and to independently operatethe locks on the doors, the fuel fillercap, the glove box and the passen-ger air bag disarming switch. Central locking From the doors (keeping the key turned in the locked position for afew seconds) the keys allow you tolock, deadlock and unlock the doorsand the boot, as well as fold back theexterior mirrors. If one of the front doors or the boot is open, central locking is not possible.In this case a bleep indicates lockingby remote control. The remote control performs the same functions at a distance.The remote control Deadlocking Deadlocking renders ithe internal and external door controls inopera-tive. Press button
Ato deadlock the vehi-
cle. This is confirmed by fixed light- ing of the direction indicators forapproximately two seconds. Another press on button  A, within
five seconds of deadlocking, changes this to  normal locking .
This is confirmed by fixed ighting ofthe direction indicators for approxi-mately two seconds, accompaniedby a brief sound of the horn. Unlocking Press button  Bto unlock the vehicle.
This is confirmed by rapid flashing of the direction indicators. Note: 
avoid handling the button of
your remote control when out of
range of your vehicle. You run therisk of stopping it from working. Itwould then be necessary to repro-gramme the remote control.
ELECTRONIC ENGINE  IMMOBILISER This locks the engine management system as soon as the ignition has
been switched off and therefore pre-vents starting of the vehicle by any-
one who does not have the key. The ignition key has an electronic chip which has a special code.When the ignition is switched on, thecode is recognised and starting ispossible. If the system does not function correctly , contact a PEUGEOT
dealer as soon as possible.

Make a careful note of the number on each key.  The key number is coded on the label attached to the key. If the keys are lost, your PEUGEOT dealer can rapidly supply you with new keys.The high frequency remote control is a sensitive system; do not operate it while it is in your pocket as there is a
possibility that it may unlock your vehicle, without you being aware of it.The remote control does not operate when the key is in the ignition, even when the ignition is switched off, except for reprogramming. 
However, do not operate the deadlocking function if there is anyone inside the vehicle.Driving with the doors locked may make access to the passenger compartment by the emergency services more difficult 
in an emergency. As a safety precaution (with children on board), remove the ignition key when you leave the vehicle, even for a short time.Do not repeatedly press the button of your remote control out of range of your vehicle. Y ou run the risk of stopping it from working and the remote control would have to be reprogrammed.
When purchasing a second-hand vehicle:- ensure that you are given the confidential card;
- have the key codes memorised by a PEUGEOT dealer, to ensure that the keys in your possession are the only ones which can start the vehicle.
Do not make any modifications to the electronic engine immobiliser system.

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
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: - 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.

The gearbox functions in autoadaptive mode without any
action on your part. When the engine is idling
with position 
R, D, 3, 2or
1 selected and the brakes
off, the car will move even
without you accelerating.  For this reason,  do not leave

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", 
situated 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 multifunction display: the ESP
and ASR systems no longer affectthe operation of the engine or thebrakes. They engage again:☞ automatically when the ignition is 
switched off,
☞ manually by pressing the switchagain. 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 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.  Ifthere 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.
