In frosty weather, make sure that
the wiper blades are not stuck by ice
(risk of motor overheating).
Keep an eye on the condition of the
blades. They should be replaced as
soon as they become less efficient.
This will occur approximately once

SPECIAL FEATURES OF PETROL VERSIONS
The following operating conditions:
– driving for long periods when the low
fuel level warning light is lit;
– using leaded petrol;
– using oil or fuel additives which are not approved by the manufacturer.
Or operating faults such as:
– faulty ignition system, running out of fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power,
may cause the catalytic converter to
overheat, reducing its efficiency which
may irreparably damage it and cause
heat damage to the vehicle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved Dealer.
These faults may be avoided by reg-
ularly taking your vehicle to your ap-
proved dealer at the intervals speci-
fied in your Maintenance Service
Document.
Starting problems
To avoid damaging the catalytic con-
verter,
do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
starting fault.
If the fault cannot be identified, do not
continue to try and start the engine, but
contact an approved dealer.
Do not park the vehicle or
run the engine in locations
where combustible sub-
stances or materials such
as grass or leaves can come into
contact with a hot exhaust system.

Transmission : 4 roues motrices (4WD) (H79 - Dacia)
ENG_NU_1079-3_H79Ph2_Dacia_2
TRANSMISSION: 4-wheel drive (4WD) (2/4)
This problem may be resolved by chan-
ging the tyres. Always use four identi-
cal tyres (same brand, profile, etc.) and
with similar wear.
In the event of excessive wheelspin,
the mechanical components may be
overheating.
If this happens:
– at first, the
’ warning light
flashes. “4WD Lock” mode is still
active, however we recommend that
you stop as soon as possible to allow
the system to cool down (until the
warning light stops flashing);
– if the wheels still spin, the system au- tomatically switches to “2WD” mode
to protect the mechanical compo-
nents.
The
‘ warning light flashes. The
mode cannot be changed while the
light is flashing.
After one minute, the system switches
to “2WD” or “AUTO” mode depending
on the position of the selector.
Note: if the vehicle speed exceeds
36 mph (60 km/h) in 4WD Lock mode,
the system automatically switches back
to AUTO mode. The
’ indicator
light goes out.
Special features of the
4-wheel drive transmission
The vehicle may make more noise when
the “AUTO" or "4WD Lock" modes are
activated. This is normal. If the system
detects a difference in the dimensions
of the front and rear wheels (eg. un-
derinflation, severe wear on an axle),
the system automatically switches to
"2WD" mode.
The
‘ and Ò warning lights on
the instrument panel come on. Drive as
soon as possible at a moderate speed
to an approved dealer.
To deactivate this mode, turn selector
1
to the “AUTO” position. The
‘ indi-
cator light on the instrument panel goes
out.
“4WD Lock" mode
To activate this mode, turn selector 1 to
the “4WD Lock” position. The selector
the returns to the “AUTO” position. The
’ indicator light will light up on the
instrument panel.
Operating principle
“4WD Lock” mode distributes the
engine torque between the front and
rear axles in order to optimise the per-
formance capacity of the vehicle in off-
road situations. This mode should only
be used in extreme driving conditions
(mud, steep slopes, sand).
To deactivate this mode, turn selector 1
to the “4WD Lock” position again. The
indicator light on the instrument panel
goes out. When the engine is switched
off, the system stays in “4WD Lock”
mode for one minute.

work, check the condition of the fuses.
Unclip flap A using notch 1 to help you.
Depending on the vehicle, to identify
the fuses, refer to the fuse allocation
label located at the back of the flap A
and shown on the following pages.
Check the fuse in question
and replace it, if necessary,
with a fuse of the same

If a fuse is fitted where the rating is
too high, it may cause the electrical
circuit to overheat (risk of fire) in the
event of an item of equipment using
an excessive amount of current.
To comply with current legislation, or
as a precaution, you can obtain an
emergency kit from your approved
Dealer containing a set of spare
bulbs and fuses.

(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.

OPERATING FAULTS (4/5)
Radiator: If there is a significant lack of coolant, remember that it must never b\
e topped up using cold coolant while
the engine is very warm. After any procedure on the vehicle which has involved even partial draining of the cooling
system, it must be refilled with a new mixture prepared in the correct p\
roportions. Reminder: only products approved
by the Technical Department may be used for this purpose.
On the road POSSIBLE CAUSES WHAT TO DO
Whistling Roof aerial poorly positioned. Position the aerial.
The engine overheats. The coolant
temperature indicator light comes
on. Engine cooling fan not working. Stop the vehicle, switch off the engine and
contact an approved dealer.
Coolant leaks. Stop the vehicle, switch off the engine and
check the coolant reservoir: it should con-
tain fluid. If there is no coolant, consult an
approved dealer as soon as possible.
The oil change warning light remains
lit after an oil change. Warning not reset after oil change.
Reset the warning after changing the oil;
