BATTERY: breakdown
Starting the vehicle using the
battery from another vehicle
Proceed as follows when starting
your vehicle from another vehicle's
battery:
obtain the appropriate leads (large
cross-section) from a RENAULT
Dealer, or if you already have jump
leads, check that they are in perfect
condition.
The two batteries must have an
identical voltage: 12 volts.
An iced-up battery must be thawed
out before current is supplied to it.
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.
(continued)
Connect the positive cable (+) to the
(+) terminal of the discharged
battery, then to the (+) terminal of
the battery supplying the current.
Connect the negative cable (–) to the
(–) terminal of the battery supplying
the current and then to the (–)
terminal of the discharged battery.
Check that there is no contact
between the cables and that the (+)
cable is not touching any metal
parts on the vehicle supplying the
current.
Start the engine as normal. As soon
as it starts, disconnect the cables in
the reverse order to the order of
connection.
