2018 RENAULT MASTER check engine

4.8
LEVELS (1/3)
 Brake fluid
This should be checked frequently,
and immediately if you notice even the
slightest loss in braking efficiency.
The level should be read with the engine
switched off and on level ground.Level 1
It is normal for the level to drop as the
brake shoes become worn, but it must
never drop lower than the “
MINI” warn-
ing line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from our network or from the
manufacturer’s website.
Filling
After any operation on the hydraulic cir-
cuit, a specialist must replace the fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).
Replacement intervals
Refer to the Maintenance Document for
your vehicle.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.

Please note when work-
ing close to the engine that
it may be hot. In addition,
the engine cooling fan may
start at any moment. The

warning light in the engine compart-
ment reminds you of this.
Risk of injury.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).

4.9
 Coolant
With the engine switched off and on
level ground, the level when cold must
be between the “ MINI” and “MAXI”
marks on the coolant reservoir 2.
Top this level up when cold before it
reaches the “MINI” mark.
LEVELS (2/3)
Frequency of checking coolant level
Check the coolant level regularly
(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– anticorrosion protection of the cool- ing system.
Replacement intervals
Refer to the Maintenance Document for
your vehicle.

Filling
With the engine switched off, open
cap 3, fill until you can see the fluid,
then refit the cap.
Fluid
Special windscreen washer fluid (prod-
uct with antifreeze in winter).

Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.

4.13
When the ignition is off, some consu-
mers may also be switched off (dipped
beam headlights, radio, ventilation,
etc.). On the instrument panel, the mes-
sage “BATTERY MODE: ECONOMY”
appears when switched off. When the
level is extremely low, the message
“BATTERY LOW START ENGINE” is
displayed.
The charge status of the battery can
decrease, especially if you use your
vehicle:
– for short journeys;
– for driving in town;
– when the temperature drops;
– with the vehicle stopped and the engine off.
Replacing the battery
As this operation is complex, we advise
you to contact an approved Dealer.

This is located behind step A and does
not require maintenance. You should
not open it or add any fluid .
Depending on the vehicle, a system
continuously checks the battery charge
status.
Handle the battery with care as it contains sulphuric acid, which must n\
ot
come into contact with eyes or skin. If it does, wash the affected area with
plenty of cold water. If necessary, consult a doctor.
Ensure that naked flames, red hot objects and sparks do not come into
contact with the battery as there is a risk of explosion.
Label B
Observe the indications on the battery:
– 1 naked flames and smoking are for-
bidden;
– 2 eye protection required;
– 3 keep away from children;
– 4 explosive materials;
– 5 refer to the handbook;
– 6 corrosive materials.
The battery is a speci-
fic type, please ensure it
is replaced with the same
type. Consult an approved
dealer.

TYRE INFLATION KIT (3/6)
To connect the compressor, open the
bonnet and connect black clamp 10
to earth 6 (refer to the information on
“Battery: troubleshooting” in Section 5).
Then connect red clamp 11 to termi-
nal 5.
Before starting the engine,
check that the handbrake is
applied and the gear lever
is in neutral or in position N
for sequential gearboxes.
With the engine running, press switch 7
to start inflating.
After a maximum of 15 minutes, stop in-
flating and read the pressure on pres-
sure gauge 9.
A pressure of at least 4.7 bar must be
reached.
Note: while the bottle is emptying (ap-
proximately 30 seconds), the pressure
gauge 9 will indicate briefly a pressure
of up to 6 bars, then the pressure drops.

If the correct pressure cannot be
achieved, repair is impossible. Do
not drive the vehicle. Consult an ap-
proved dealer.
If the pressure is too high, press
button 8 to lower the pressure.

FUSES (1/5)
1
If any electrical component does not
work, check the condition of the fuses.
Remove the fuse using tweezers 1, lo-
cated at the back of flap A.
To remove the fuse from the tweezers,
slide the fuse to the side.
It is not advisable to use the free fuse
locations.
To comply with legislation, or as a
precaution, you can obtain an emer-
gency kit containing a set of spare
bulbs and fuses from an approved
dealer.
Your vehicle is equipped with two fuse
boxes: in the passenger compartment
and in the engine compartment.
A
Fuses in the passenger
compartment
Unclip flap A using notch B to help you.
To identify the fuses, refer to the fuse
allocation label (see the next page for
details), located on the rear of flap A.
B
Check the fuse in question
and replace it, if neces-
sary, by a fuse of the same
rating.
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.

BATTERY: troubleshooting (2/2)
Attach the positive lead (+) A to termi-
nal 3, then to terminal 2 (+) of the bat-
tery supplying the current.
Attach negative lead (–) B to terminal 1
(–) of the battery supplying the current,
then to earth 4 (–).
Start the engine as normal. As soon as
it is running, disconnect leads A and B
in the reverse order ( 4-3-2-1).
Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al-
ready have jump leads, ensure that
they are in perfect condition.
The two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Ensure that there is no risk of contact
between the two vehicles (risk of short
circuiting when the positive terminals
are connected). Switch off your vehicle
ignition.
Start the engine of the vehicle supply-
ing the current and run it at a moderate
speed.

Check that there is no contact between leads A and B and that the posi-
tive lead A is not touching any metal parts on the vehicle supplying the
current.

TOWING: breakdown (1/2)
The steering wheel must be un-
locked and the ignition key must be
in position M (ignition on) to provide
brake lights and hazard warning
lights on the towed vehicle. At night
the vehicle must have its lights on.
Unhitch the trailer, etc., if one is
being towed.
You must observe the towing regu-
lations which apply in the country in
which you are driving: do not exceed
the towing weight for your vehicle.
Contact an approved dealer.
– Use a rigid towing bar.
If a rope or cable is used
(where the law allows this),
the vehicle being towed
must be able to brake.
– A vehicle must not be towed if it is not fit to be driven.
– Avoid accelerating or braking suddenly when towing, as this
may result in damage being
caused to the vehicle.
– When towing a vehicle, it is ad- visable not to exceed 15 mph
(25 km/h).
When the engine is
stopped, steering and brak-
ing assistance are not op-
erational.
Do not remove the key from
the ignition when the vehi-
cle is being towed.
Towing a vehicle with a
sequential gearbox
If the gearbox is stuck in a gear:
– switch on the ignition;
– select neutral with the brake pedal depressed;
– check that the gearbox is in neutral (by pushing the vehicle for example).
If you cannot find neutral you must tow
the vehicle with the front wheels raised.
The vehicle should always be towed
with the ignition switched off.
