BATTERY: failure
Starting the vehicle using the
battery from another vehicle
Proceed as follows when starting
your vehicle from another vehicle's
battery:
Obtain suitable jump leads (with
a large cross section) from a
RENAULT Dealer or, if you already
have jump leads, ensure that they
are in perfect condition.
The two batteries must have an
identical voltage: 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah)
which is at least the same as that
of the discharged 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
supplying the current and run it at
an intermediate engine speed.
