Ð service indicator,
Ð total distance recorder. Engine oil level When the ignition is switched on, the engine oil level indicator is displayed for approximately five seconds, then the service indicator is displayed for five seconds.
Maximum Use the dipstick to confirm the level on the indicator; a surplus of oil can cause damage to the engine.
Contact a PEUGEOT dealer as soon as possible. Minimum
Check the level with the dipstick and top it up. The indication is only correct if the vehicle has been on stable, level ground, withthe engine stopped, for 10 minutes. No oil It is essential to top up the oil to the correct level, otherwise there is a risk the engine will be damaged.

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.

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.

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''

BATTERY
To charge the battery using a battery charger:
Ð Disconnect the battery,
Ð Follow the instructions for use given by the battery charger manufacturer,
Ð Reconnect starting with the negative (Ð) terminal,
Ð Check that the terminals and connectors are clean. If they are covered with sul-phate (white or greenish deposit), disconnect them and clean them.
To start the vehicle from another battery:
Ð Connect the red cable to the positive (+) terminals of the two batteries,
Ð Connect one end of the green or black cable to the negative (Ð) terminal of the slave battery,
Ð Connect the other end of the green or black cable to an earth point on the bro- ken down vehicle, as far as possible from the battery,
Operate the starter, let the engine run.
Wait for the engine to return to idle, then disconnect the cables.
Ð Never disconnect a terminal when the engine is running.
Ð Never charge a battery without first disconnecting the terminals.
Ð Close the sunroof before disconnecting the battery. If it does not operate normally following re-connection of the battery, you must
re-initialise it by turning the control to the maximum tilt position and pressing it for a few seconds.
Ð After every reconnection of the battery, switch on the ignition and wait 1 minute before starting to allow the electronic systems to be initialised. Ifslight difficulties are experienced after this, please contact a PEUGEOT deal-
er.
It is advisable to disconnect the battery if the vehicle
is not to be used for a period of more than one month.
Economy mode
With the engine switched off and the ignition key in the "running" or"accessories" position for about half
an hour, certain electrical equipment(displays, instrument panel, warninglights, courtesy lights, electric win-
dows, wipers etc.) will switch offautomatically to avoid draining the
battery. Once the electrical equipment goes into economy mode, it is necessaryto start the engine to enable theequipment to work again.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage ofyour vehicle. The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically designed for transporting people and luggage butit may also be used for towing a
trailer. Driving with a trailer subjects the towing vehicle to more significantstress and its driver must be particu-larly careful. Air density decreases with altitude, thus reducing engine performance.The maximum towing load must
be reduced by 10 % for every
1 000 metres of altitude. Driving advice Distribution of loads: Distribute the
load in the trailer so that the heaviest items are as close as possible to theaxle and the nose weight approach-es the maximum permitted withoutexceeding it. Cooling:
Towing a trailer on a slope
increases the temperature of thecoolant. As the fan is electrically controlled, its cooling capacity is not dependenton the engine speed.
On the contrary, use a high gear to lower the engine speed, and reduceyour speed. The maximum towing speed on a long slope depends on the gradientand the outside temperature. For vehicles fitted with a direct injec- tion petrol engine, after towing or dri-ving at high speed for a long periodof time, the fan may operate forapproximately 6 minutes. In all cases, pay attention to the coolant temperature. If the warning light comes on, stop
the vehicle and switch off the engineas soon as possible. Tyres:
Check the tyre pressures of
the towing vehicle and the trailer,observing the recommended pres-sures. Brakes: Towing increases the braking
distance. Lights: Check the electrical sig-
nalling on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
