Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al-
ready have jump leads, ensure that
they are in perfect condition.
The two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Ensure that there is no risk of contact
between the two vehicles (risk of short
circuiting when the positive terminals
are connected) and that the discharged
battery is properly connected. Switch
off your vehicle ignition.
Start the engine of the vehicle supply-
ing the current and run it at a moderate
speed.

Check the condition of the wiper
blades. You are responsible for their
service life:

water;
– do not use them when the wind- screen or rear screen are dry;
– free them from the windscreen or rear screen when they have not
been used for a long time.

– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating).
– Check the condition of the wiper
blades.
Replace the wiper blades as soon
as they begin to lose efficiency
(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.
