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

DISMOUNTING- REMOUNTING
DISMOUNTING
Af ter identification and elimination of the real cause of the battery discharging, proceed as
follows:
Remove the plastic protector from the plus plug of the battery.
Dismount the attachment nut of the ground wiring from the minus plug of the battery.
Dismount the attachment nut of the wiring from the plus plug of the battery.
Dismount the battery attachment clamp screw.
Carefully take off the battery.
REMOUNTING
Perform the dismounting operations in the reverse order. After that, reset the radio by introducing
the radio code (if the vehicle is equipped with radio) and adjust the dashboard clock. BATTERY

FOG LAMPS
DISMOUNTING – REMOUNTING
Disconnect the fog lamp (A) connectors from the vehicle wiring.
Dismount the two fog lamp attachment nuts (B and C) on the front bumper.
Remove the fog lamp off the bumper.
Position in the bumper the new fog lamp.
Mount the two fog lamp attachment nuts (B and C).
Connect the fog lamp (A) connectors to the vehicle wiring.
Check the operation of the fog lamps.
NOTE:
After mounting t he fog l amps, it is obl igatory to perform their adjustment.

DISMOUNTING
Disconnect the (-) plug of the battery.
Turning the button
(4) open, then carefully remove the access little door (1) to the fuse box,
placed under left side dashboard. Dismount the attaching screws (2) of the fuse box on back of the little door.
Rotate the fuse box in order to have access at the connectors of its back then carefully discon-
nect the wiring connectors. If it is necessary the replacement of the module (3 ) attached on the
fuse box, for the fuses F11 – F16, first note the position of the wires connected to these fuses,
then perform the wires disconnecting .
Remove the fuse box.
REMOUNTING
Connect the wiring connectors to the fuse box printed circuit. Observe the form correspon-
dence of each connector with its drawing, marked on the printed circuit of the fuse box. Connect the wires corresponding to the fuses F11 – F16, if those have been previously disconnected.
Position the wires appointed for the fuses F11- F16 and the module (3) of those fuses, then
attach the fuse box on the back of the access little door (1).
Carefully mount the fuse box access little door, then close it.
Connect the (-) battery plug.
Perform functional tests, noticing the correct operation of all consumers supplied by means of
the cockpit fuse box.
OBSERVAT ION
For vehicle equipped with radio-tape player, after battery reconnecting, the radio
code must be introduced, in order to make it again running.

ll the new decoders, are not coded. After t he mounting on the vehicle it is necessary the
memori sation of t he key head code by the decoder i n order to be operational. If only the
decoder is replaced, no intervention is necessary to the injection computer, which will keep the
old anti starting code. When the vehicle is provided with RF remote control for blocking/unlocking
the doors, the performing of the resynchronisation of the keys with the decoder is imposed, after
its mounting.
If further to the diagnostic of the anti starting system, using the CLIP tester, the replacement of
the decoder is imposed, proceed as follows: - disconnect the front wiring connector from the E.C.U. decoder ( the contact being off);
- dismount the attachment screws of the E. C. U. decoder on the front left pillar;
- mount the new E.C.U. decoder;
- connect the front wiring to the new decoder.
Proceed then to the insertion of the anti starting code using the contact key, then to its memorising
(validation) in the E.C.U. decoder, using the CLIP tester. For this purpose, perform the “E.C.U.
decoder re placement procedure and a nti starting c ode memorising”. Che ck then the correct
operation of the anti starting system with both keys. E.C.U. DECODER REPLACEMENT
AT TENT ION
Once the decoder has memorised the key codes, this code cannot be erased
or replaced with another one.
If it is necessary the replacement of the kit (E.C.U. decoder and two key heads), after that
realise t he “ Kit replacement procedure”.

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
