GENERAL INFORMATION
All information contained in these manuals is intended
exclusively for automotive industry professionals.
The documentation is intended to cover all vehicles in
the RENAULT range throughout the world, but may not
cover equipment designed for use in specific countries.
The procedures and fault finding procedures recom-
mended and described in this manual have been de-
signed by automotive industry repair professionals.
1 - General recommendations
Observe basic principles of vehicle repair.
The quality of repair depends first and foremost on the
care exercised by the person in carrying it out.
To ensure good repair:
-protect the sensitive areas of the vehicle (seats,
steering wheel, wings, etc.),
-unless otherwise indicated, all repairs must be done
with the ignition off,
-when welding on the vehicle, it is advisable to remove
or disconnect components near the repair area that
could be affected by the heat,
-use recommended professional products and original
parts,
-observe the tightening torques,
-replace roll pins, self-locking or bonded nuts or bolts
every time they are removed,
-take care with electrical and electronic components
which cannot withstand excess voltage and improper
handling; replace any electrical and electronic com-
ponents which have experienced a voltage drop,
-make sure that the connectors are correctly clipped,
-do not pull on the wiring,
-check for the sealing plugs on the connectors,
-Do not splash any liquid, regardless of its type (oil,
cleaner, etc.), on the electric and electronic compo-
nents (computers, sensors, etc.)
-do not just replace parts one after the other, carry out
detailed fault finding beforehand,
-carry out a final check before returning the vehicle to
the customer (set the clock, check the alarm opera-
tion, check the lights and indicators etc.),
-clean and degrease the sections to be bonded
(threads, stub axle splines) to ensure proper adher-
ence,-protect the accessories and timing belts, the electrical
accessories (starter, blanking cover, electric power
assisted steering pump) and the mating face to pre-
vent diesel fuel spilling onto the clutch friction plate.
The design quality of our vehicles demands that noth-
ing is left to chance in making a good repair, and it is
essential to refit parts or components exactly as they
were originally (for instance: heat shields, wiring rout-
ing, pipe routing, particularly in the area of the exhaust
pipe).
Do not blow away asbestos particles or dust (brakes,
clutch, etc.), vacuum them up or clean the component
with a cleaning agent (such as a brake cleaning prod-
uct).
Use professional products and apply them with care,
for example do not apply too much sealing paste to the
sealing surface.
Exhaust gases (petrol and diesel) are pollutants. Oper-
ate engines with care and always use exhaust gas ex-
tractors.
Ensure that there is no risk of a short circuit occurring
when the electrical connections are reconnected (e.g.
starter, alternator, etc.). Some points need greasing,
others do not, therefore particular attention should be
paid during refitting operations to ensure that they work
properly under all conditions.
2 - Special tooling - ease of use
The repair procedures have been designed using spe-
cial tools; they must therefore be carried out using
these tools to ensure a high degree of working safety
and quality of repair.
The equipment we have approved has undergone
careful research and testing, and must be used and
maintained with care.
3 - Reliability - updating
New repair procedures are constantly being developed
in the interests of repair quality, either with new prod-
ucts (emission control, injection, electronics, etc.), or in
fault finding. Be sure to consult the Workshop Repair
Manuals or Technical Notes or fault finding summaries
before any servicing operation.
Since vehicle specifications are subject to change dur-
ing their commercial life, it is essential to check wheth-
er there are any updated Technical Notes when
seeking information.

4 - Safety
Operations on certain equipment and certain parts (for
instance: spring-shock absorber assembly, automatic
transmission, brake system, ABS, airbag, common rail
diesel injection, LPG, etc.) require particular attention
to be paid to safety, cleanliness and care.
The safety symbol used in this manual indicates that
special attention must be paid to the procedure or the
tightening torque values.
Working safely:
-use suitable tools which are in good condition (use of
« multi-purpose » tools, such as adjustable pliers,
etc., should be avoided wherever possible),
-use supports and adopt a correct posture when per-
forming heavy work or raising loads,
-make sure that the procedure used is not dangerous,
-Do not wear any jewellery or other small objects dur-
ing an operation,
-use personal protection (gloves, safety glasses, work
shoes, masks, skin barrier creams, etc.),
-always follow the safety instructions associated with
the operation to be performed,
-do not smoke when working on vehicles,
-use smoke extractors (welding, exhaust gases, etc.),
-do not use harmful products in unventilated rooms,
-do not overstrain yourself or attempt inappropriate
work operations,
-use axle stands when working under a vehicle raised
on a jack,
-do not ingest any chemicals (brake fluid, coolant,
etc.),
-do not open the cooling circuit when it is hot and pres-
surised,
-take care with components that are liable to start up
suddenly (engine cooling fan, etc.).
Respecting the environment:
-do not allow waste refrigerants to escape into the at-
mosphere,
-do not dispose of waste vehicle fluids (oil, brake fluid,
etc.) in drains,
-do not burn discarded products (tyres, etc.).5 - Conclusion
The procedures contained in this document merit your
attention. Please read them carefully in order to reduce
the risk of injury, and avoid using incorrect procedures
that could damage the vehicle or make it dangerous in
use.
Following the recommended procedures will help you
to provide a quality of service which will ensure the ve-
hicles achieve the highest levels of performance and
reliability.
Maintenance and repair operations must be carried out
under the proper conditions to ensure that our vehicles
run safely and reliably.
