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 t hem.
To start the vehicle from another battery:
Connect the red cable to the positive (+) terminals of the tw o batteries,
Connect one end of the green or black cable to the negat ive (–) terminal of the
slave battery,
Connect the other end of the green or black cable to an e arth 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 th e cables.
Never disconnect a terminal when the engine is running.

TOWING A TRAILER,
CARAVAN, BOAT ETC.
Only use original PEUGEOT tow
bars that have been tested and
approved from the design stage of
your vehicle.
The tow bar must be fitted by a
PEUGEOT dealer.
Your vehicle is basically 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 significant
stress 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
1000 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 the axle and the nose
weight approaches the maximum
permitted 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 dependent
on the engine speed.
On the contrary, use a high gear to
lower the engine speed, and reduce
your speed.
The maximum towing speed on a
long slope depends on the gradient
and the outside temperature.
For vehicles fitted with a direct injec
tion petrol engine, after towing or dri
ving at high speed for a long period
of time, the fan may operate for
approximately 6 minutes.
In all cases, pay attention to the
coolant temperature.
If the warning light comes on, stop
the vehicle and switch off the engine
as soon as possible.
Tyres:
Check the tyre pressures of the tow
ing vehicle and the trailer, observing
the recommended pressures.
Brakes:
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.
