BATTERY
CHECKING
It is recommended to check the following: -cr acks or breaches of the battery box (case);
- the battery upper part cleanness;
- the plugs condition.
It is required to strictly check the following: -lack of plugs sulfate composite;
- proceed, is necessary to their cleaning and greasing;
- check the correct wiring plugs tightening at the battery plugs. The existence of an imperfect
contact may generate incidents at engine starting or at battery charging, sparks producing risk
being possible to occur, which may cause the battery explosion;
- check the electrolyte level.
For the batteries provided with access plugs, which may be dismounted, proceed as follows:
-r emove the plugs;
- check the electrolyte level in each element;
-i f n ecessary , refill the level, using only distill ed water, till maximum 1.5 cm above the plates.
AT TENT ION
N ever fill up with electrolyte, but only with distilled wat er.
PRECAUTIONS
It is important to know that: -the battery contains sulfuric acid which is a dangerous substance;
- during battery charging, oxygen and hydrogen are produced. The mixture of these two
gases is forming a detonate gas, which may lead to the explosion risk.
1. DANGER = ACID
The sulfuric acid solution is a very aggressive, toxic and corrosive product. This is a ttacking
the skin, the clothes and may lead to the corrosion of most of the metals. Also, it is very important, that, when you handle a battery , to consider the following precautions:
- protect the eyes by using protective glasses;
- wear anti-acid gloves and clothes. PARTICULARITIES

AT TENT ION
In case of acid slashes on body, abundantly wash with water al l affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current. The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
AT TENT ION
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are
shouted off; -during battery charging in a room, using a c harger-rectifier, turn it off be fore
connecting or reconnecting the battery to this one;
-do not place m etallic objects on the battery for not producing a short-circuit
between its plugs;
-never bring closer to a battery, an open flame, a welding lamp or another fire
source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing. The
battery is to be allwith disconnected by first disconnecting the negative plug and then the positive
one. Connection is to be done by performing the disconnecting operations in the reverse order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the ground), and if the plugs are clean and well tightened. Never disconnect the battery when
the engine is running, in order not to damage the voltage regulator, the alternator or some
components of the vehicle checking electronic systems. The alternator, voltage re gulator
disconnecting, a nd the interventions at their connections, are to be performed only when the
engine is stopped (the alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs. BATTERY

If further to the diagnostic, it is established
the necessity of the replacement of the anti starting
bushing, proceed as follows: -dismount the attachment screws of the steering wheel casing ;
- unlock the steering wheel and bring it in low position;
-r emove the steering wheel upper casing;
- disconnect the anti starting bushing connector from the front wiring;
-r emove the bushing;
- mount the new bushing outside the starting contact (anti theft) system;
- connect the bushing connector to the front wiring;
- mount the steering wheel casing;
- check the operation of the indicator and the anti starting system when the contact is off,
then with the contact on and the engine started. ANTI STARTING BUSHING REPLACEMENT

The RF remote control has no influence on anti starting system. It has only the function of
blocking/ unlocking the doors. The RF remote control with evolutionary code can use only two
keys as the decoder may manage only two different evolutionary codes. The key heads have an identification number formed by 8 alphanumeric characters (letters
and figures) , beginning with letter E.
In case of loosing one key, a key head and a metal insert ion will be ordered, then the
resynchronisation procedure of the RF remote control of t he ke y with t he decoder from the
vehicle must be performed. If the vehicle is provided with RF remote control key and this one
has been replaced, then perform the “ Simple synchronised procedure “. When the vehicle has
both keys with RF remote control, then perform the “Specific synchronised procedure “ after the
replacement of the second key.
NOTE - In the case only one ke y head is replaced, usually there is no need for
r esynchronisation of the other RF remote control.
- If both RF remote controls are desynchronised, one procedure of resynchronisation
will be performed with each remote control: perform the “Simple synchronisation
procedure for the first RF remote control” and the “Specific synchronisation procedure”
for the second RF remote control. Check then t he operation of blocking/ unlocking of the doors with both RF remote
controls. RF REMOTE CONTROL FOR BLOCKING/ UNLOCLING
