BRAKE FLUID
PERIODICITY OF THE BREAK FLUID CHANGE
The manufacturing conception of the brakes equipping the Dacia vehicles, especially
the di sks brake type (F 54 inner empty pistons, low qua ntity of fluid in t he c ylinders,
sliding calipers avoiding existence of a fl uid reserve in the less cooled area of t he wheel)
enable t he m aximum re jection of fluid vapori zation ri sk, even in c ase of intensive using of
brakes (mountain are a). The current bra ke fluids are subject in all cases to a slight degradation during the fi rst
months of use by a slight humidity absorpt ion seri es (see the Vehicle Warra nty and
Maintenance Booklet, for brake fluid change)
LEVEL COMPLETION
The wear of brakes pads and shoes generate a gradually diminution of brake fluid level
in its reservoi r. It is useless t o compensate t his diminution, because the level will be re -
stored in the moment of next changing the brake pads and shoes. Obviously, in the mean-
time, the level of brake fl uid in re servoir must not go down bellow the minimal mark.
HOMOLOGATED BRAKE FLUIDS
The mixture i n t he bra king circuit of two non compatible brake fluids may leads to loss
important risks mainly due to gasket damage
In order t o avoid such risks, it is obligatory t o use bra ke fluids checked and approved by
our laboratories and which are accordi ng to Norm SAEJ 1703, DOT 4.

Retrieve the feeding pipe (towards the arrow) to enable the fluid passing through the connection 1.
Bleed a little bit of fluid.
Close the purging connection (move the feeding pipe in reverse way).
2. FINAL PURGING OF THE CIRCUIT
a) Slowly push the clutch pedal to maximum position and keep it pushed.
W ait aprox. 10 seconds then open the purging connection.
b) Close the purging connection, release the clutch pedal, and slowly lift it by hand to
the upper position ( if the pedal does not come back itself in this position ).
Repeat the operations a and b till bubbles are not coming our through the purging.
connection, then repeat five more times these operations in order to be sure about a good circuit
pur ging.
These repeated purging allow “ the c leaning “ of the circuit from the air bubbles eventually
remained in the circuit after the circuit filling and purging.
An air bubble as little may be, remained in the circuit, may lead to operating deficiencies such
as: defective clutch pedal return or gears change noise being able to lead to a wrong diagnosis or
an inopportune replacement of a part of the clutch circuit.

GEARS CONTROL ADJUSTMENT
This is to be performed after mounting the engine-gearbox assembly and the assembly lever-
control case every time when : - dismounting of the engine-gearbox a ssembly, t he c ontrol ba r or the assembly lever-
control case;
- establishin g of failures such as: gear change impossibility or unexpected gear uncoupling,
gear blocking.
For the gear control adjustment the CV 550 device i s to be used;
M ount the CV 550 device on the assembly lever- control c ase;
A ttach the control bar to the control lever end;
Place the gear lever in the device seat and fix it in this position by means of the device handle;
Tighten the attachment screw 1 of the bar to the lever at the required moment of 1.2 daNm;
Dismount the CV 550 device from the control box.
Check the gears coupling. THE GEARS CONTROL

OLLISION DIAGNOSIS
Du ring the vehicle exploitation, the carriage body may suffer different distortions, that
lead many times to the wheels setting angles change, body elements breakage, vibra tions
or even mechanical parts wear. In these conditions, be fore performing the vehicle body re paration, some checking is
necessary:
Visual checking - consisting in the e xamination of the mechanical elements attachments
and of the distortions occurring in the vehicle damaged areas.
Checking with the bar (control gauge) – consisting in comparing the measurements
done in symmetric points. The ge ometry checking of t he rol ling t ransmissions – this checking is t he only one
enabling to find out if the body damage was not affecting the vehicle road behavior.
IMP ORTANT
This checking must be not ignored, except some border-line cases, the checking of
the rolling transmissions leading to t he identification of the distortions occurred further
to an accident.

THE PIN CODE
The PIN code is formed of four figures and it can be used only for deactivating the anti intrusion
s ystem, if this operation can not be performed by pushing the deactivating button from the RF
remote control of the vehicle. For introducing the PIN code, perform as follows:-set on the contact key in the M position and take it off it for three times in seven seconds,
after which the anti intrusion LED indicator will switch on for three seconds; -set on the contact again on the M position and maintain it until the number of the L ED
blinks is e qual with the first figure of the PIN code, then take off the contact; -set on the contact in the M position and maintain it until the number of LED blinks is equal
w ith the second figure of the PIN code, then take off the contact;
-perform the above mentioned method in order to introduce the third and the fourth figure
of the PIN code;
-after that, the system is deactivated and the siren stops automatically;
- set on the contact again – the anti LED indicator must switch on, confirming in this way
that the c orrect introduction of the PIN code.
AT TENT ION
If it i s necessary the checking of the PIN code, t his will be pe rformed
only after al least 20 seconds have passed, since the anti intrusion ECU has been
connected to the vehicle’s wiring or since the connecting of t he vehicle’s battery.
The COBRA anti intrusion system can operate in t hree different modes (2,3 or 4).
For the Super Nova vehicles, the system has been programmed to work in the second operation
mode. If by mistake the PIN code was introduced in less than 20 seconds since the battery
connecting or since connecting the anti intrusion ECU, this can involve the change of the operation
way of the system, which will generate errors during the operation. There is, although, the possibility
of reprogramming the correct operation way (type 2) and in this purpose, perform the following
operations : - disconnect and then reconnect the anti intrusion ECU; when connecting the anti intrusion
ECU the anti intrusion LED indicator will switch on once, confirming the correct connecting;
-af ter at least 5 seconds from the previous operation, but no more than 20 second from it,
perform the following operation s:
-s et on the contact key in the M position for three times and then release it;
- the anti intrusion LED indicator will switch on for three seconds and then will switch off;
- set on again the contact key in the “M” position and maintain it, counting two blinks of the
anti intrusion LED indicator, then take off the contact;
- the LED indicator will blink for two times in two series, confirming in this way the proper
performance of the previous operations;
press the doors locking button of the dashboard, in order to lock and unlock the doors; the anti
intrusion LED indicator must not blink;
