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.
Contact a PEUGEOT dealer to have the system checked. Follow me Home When there is a low level of bright- ness or at night, if you leave yourvehicle, the side lights and thedipped beam lights may remain onfor approximately one minute.
To do this:
☞ place the lights stalk in the AUTO
position,
☞ place the key in the accessories position (first notch),
☞ press the end of the lights stalk formore than two seconds,
☞ place the lights stalk in the 0posi-
tion,

Ð vehicle load.
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
children unsupervised inside the vehicle when the engine isrunning. If work needs to be done with the engine running, apply thehandbrake and select position P
.
Never select position Nwhen the
vehicle is moving. Never select position Por R

Note: For immediate maximum acceleration
without touching the gear lever, pressthe accelerator pedal down as far as it
will go (kickdown). The gearbox willchange down automatically or stay inthe gear selected, up to maximumengine speed. When braking, the gearbox changes down automatically to provide
efficient engine braking.
If you take your foot off the
accelerator suddenly, the gearboxwill not change up for reasons of
safety.

Sport and Snow programmes In addition to the autoadaptive programme, two special
programmes are available. Theindicator light corresponding to theprogramme selected lights up on theinstrument 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 anomalyAny disruption of the system is indicated by the alternate flashing ofthe sport and snow lights on theinstrument panel. In such a case, the gearbox will operate in downgrade mode (locked

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.

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 accelerator or brake pedals. In order for it to be memorised, the vehicle speed must be greater than25 mph (40 km/h) or 37 mph (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.
Y our 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 the
previous 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 inheavy traffic. THE ABS ANTI-LOCK BRAKINGSYSTEM
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.
