CHANGING A FUSE The fuse boxes are located under the fascia (driver's side) and in theengine compartment. The spare fuses and special pliers A
are fixed to the inside of the lid of the fascia fuse box. Removing and changing a fuse Before changing a fuse you must establish the cause of the fault and
have it corrected. The fuse numbersare indicated on the fuse box.  Use the special pliers A.
Always change a faulty fuse for one of the same rating. Fascia fuses 
Unscrew the bolt a quarter of a turn with a coin, then pull thehandle to open the cover andaccess the fuses.

CHANGING A WINDSCREEN WIPER BLADE Placing the wiper blades in the maintenance position Within one minute of switching
off the ignition, operate thewipers stalk to position the wiperblades in the centre of the wind-screen (maintenance position).
Changing a wiper blade  Lift the wiper arm, then unclip the blade and remove it.
 Fit the new blade and push backthe arm.
Note : the shortest blade is fitted on
the vehicle's right-hand windscreenwiper arm.
To return the windscreen wipers to their normal position, switch onthe ignition and operate the wiperstalk. ECONOMY MODE FUNCTION After the engine has stopped, certain functions (windscreen wipers, elec-tric windows, panoramic roofconcealing flap, courtesy lights,audio equipment etc.) can only beused for thirty minutes, to prevent
discharging the battery.
Once the thirty minutes are over, the message
"Economy mode active"
appears on the multi-function displayand the active functions are put on
standby.
To resume use of these functions, start the engine and let it run for afew seconds. LOAD REDUCTIONFUNCTION When driving, certain functions (air conditioning, heated rear screen,heating system for passenger com-partment of diesel vehicles, etc.)
may be switched off temporarily,depending on the level of batterycharge. Reactivation of these functions is automatic, once the battery charge is
sufficient. Note:
at the risk of discharging the
battery, the functions that have been
switched off may be reactivated
manually.
PRACTICAL INFORMATION
152
A flat battery will prevent the engine from starting.

BATTERY
To charge the battery using a battery charger:
- Disconnect the battery,
- Follow the instructions for use given by the battery charger manufacturer,
- Reconnect starting with the negative (-) terminal,
- 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:
- Connect the red cable to the positive (+) terminals of the two batteries,
- Connect one end of the green or black cable to the negative (-) terminal of the slave battery,
- 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.
PRACTICAL INFORMATION 153
- Never disconnect a ter-
minal when the engine is running.
- Never charge a battery without first disconnecting the terminals.
- After every reconnection of the battery, switch on the ignitionand wait 1 minute before star-ting to allow the electronic sys-tems to be initialised. If slight dif-ficulties are experienced afterthis, 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.

TOWING YOUR VEHICLE
Without lifting (4 wheels on the road)
You should always use a tow bar. The removable towing eye is inside the boot right-hand trim. From the front: Unclip the cover, by pressing the bottom part,
 Screw in the removable towing eye as far as it will go.
From the rear: Unclip the top of the cover using a coin,
 Screw in the removable towing eye as far as it will go.
Lifting (2 wheels only on the road ) It is preferable to raise the vehicle with a professional lifting device. Special features of the automatic gearbox When towing with four wheels on the ground, the following rules must beobeyed:
- lever in position
N,
- tow the vehicle at less than 50 km/h over a maximum distance of 50 km,
- do not add oil to the gearbox.
PRACTICAL INFORMATION
154
When towing with the engine switched off, thereis no braking or steeringassistance.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage of
your vehicle. The tow bar must be fit-
ted by a PEUGEOT dealer.
Your vehicle is basically designed for transporting people and luggage butit may also be used for towing a trai-
ler. 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 1000 metres, the maximumtowing load must be reduced by 10%and so on for every 1000 metres ofaltitude.Driving advice Distribution of loads Distribute the load in the trailer so that the heaviest items are as closeas possible to the axle and the noseweight approaches the maximumpermitted without exceeding 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 braking distance. Lights Check the electrical signalling on the
trailer. Side wind
Take into acount the increased sen- sitivity to side wind.
