CHECKS Battery
At the start of winter, have your bat-
tery checked by a PEUGEOT dealer. Air filter Regular replacement of the filter ele- ment is essential. If you drive in
very dusty conditions, change ittwice as often. Brake pads Brake pad wear depends on the style of driving, in particular for vehi-cles that are used in town, for shortjourneys. It may be necessary to check the thickness of the pads even betweenservices. Handbrake Where the handbrake travel is too great or there is a reduction in theperformance of the system, thehandbrake should be adjusted, evenbetween services. Have the system checked by a
PEUGEOT dealer. Manual gearbox This does not require an oil change. Have the level checked in accor-dance with the manufacturer's ser-vicing schedule. Oil filterReplace the cartridge regularly in accordance with the servicing sched-ule.

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 oper-
ate 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 afew 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
dealer.
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 primarily designed for transporting people and luggage but
it 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.
Above 1 000 metres, the maximum
towing load must be reduced by 10 %
and so on for every 1 000 metres ofaltitude.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 approachesthe maximum permitted withoutexceeding it. Cooling: Towing a trailer on a slope
increases the temperature of the coolant. 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 load on a long slope depends on the gradient andthe outside temperature. 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 of the trailer,observing the recommended pres-sures. Braking: Towing increases the brak-
ing distance.Lights: Check the electrical signalling
on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
