USEFUL ADVICE FOR
LENGTHENING THE LIFE
OF YOUR BATTERY
To avoid draining your battery and
lengthen its life, observe the following
indications:
❒ when you park the car, ensure the
doors, tailgate and bonnet are closed
properly;
❒ the ceiling lights must be off. The car
is however provided with an auto-
matic system for switching off inter-
nal lights;
❒ do not keep accessories (e.g.: sound
system, hazard lights, etc.) switched
on for a long time when the engine
is not running;
❒ before performing any operation on
the electrical system, disconnect the
battery negative terminal cable;
❒ battery terminals shall always be per-
fectly tightened.
IMPORTANT A battery which is kept
at a charge of less than 50% (optical in-
dicator with dark colour without green
area in the middle) for any length of time
will be damaged by sulphation leading to
a reduction in cranking power.
