2018 RENAULT MEGANE warning

5.12
TYRES (2/3)
Tyre pressures
Adhere to the tyre pressures (including
the emergency spare wheel). The tyre
pressures should be checked at least
once a month and additionally before
any long journey (refer to the label af-
fixed to the edge of the driver’s door).The pressures should be checked cold:
ignore higher pressures which may be
reached in hot weather or following a
high speed journey.
If the tyre pressures cannot be checked
when the tyres are
cold, increase the
pressures from 0.2 to 0.3 bar (or 3 PSI).
Never deflate a hot tyre.
Special note
Depending on the vehicle, there may
be an adapter which needs to be posi-
tioned on the valve before air is added. Vehicle fitted with a tyre pressure
monitoring system
If under-inflated (puncture, low pressure
etc.), the warning light
 lights up
on the instrument panel; please refer to
“Tyre pressure monitoring system” in
Section 2.
Emergency spare wheel
Refer to the information on “Puncture”
and “Changing a wheel” in Section 5.
Changing wheels around
This practice is not recommended.
Incorrect tyre pressures
lead to abnormal tyre wear
and unusually hot running.
These are factors which
may seriously affect safety and lead
to:
– poor road holding,
– risk of bursting or tread separa- tion.
The pressure depends on the load
and the speed of use. Adjust the
pressure according to the condi-
tions of use (refer to the label affixed
to the edge of the driver’s door).
Please be aware that a
poorly tightened or miss-
ing valve cap can make the
tyres less airtight and lead
to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.

5.13
Studded tyres
This type of equipment may only be
used for a limited period and as laid
down by local legislation. It is neces-
sary to observe the speed specified by
current legislation.
These tyres must, at a minimum, be
fitted to the two front wheels.
Chains
For safety reasons, fitting snow
chains to the rear axle is strictly for-
bidden.
Chains cannot be fitted to tyres which
are larger than those originally fitted to
the vehicle.
TYRES (3/3)
Use in winter
Snow or Winter tyres
We would recommend that these be
fitted to all four wheels to ensure that
your vehicle retains maximum adhe-
sion. Warning : These tyres sometimes
have a specific direction of rotation and
a maximum speed index which may be
lower than the maximum speed of your
vehicle.
Snow chains may only be
fitted to tyres of the same
size as those originally
fitted to your vehicle.
In all cases, we would recommend that you contact an authorised dealer w\
ho will
be able to advise you on the choice of equipment which is most suitable \
for your
vehicle.
Changing a wheel
As the tyre pressure moni-
tor may take several min-
utes to correctly determine
the positions of the wheels and the
pressure values after driving, check
the tyre pressures following any op-
eration.17” wheels and larger
cannot be fitted with
chains.
If you wish to use special
equipment, please consult an au-
thorised dealer.
Fitting new tyres
For your safety, please re-
spect the speed limit.
When they need to be re-
placed, only tyres of the
same make, size, type and profile
should be used on a single axle.
They must: either have a load ca-
pacity and a speed capacity at
least equal to the original tyres,
or correspond to those recom-
mended by your authorised
dealer.
Failure to heed these instructions
could endanger your safety and
affect your vehicle’s roadworthi-
ness.
Risk of loss of control of the ve-
hicle.

5.14
Any operation on (or modi-
fication to) the electrical
system must be performed
by an approved dealer
since an incorrect connection might
damage the electrical equipment
(harness, components and in partic-
ular the alternator). In addition, your
Dealer has all the parts required for
fitting these units.

BATTERY: troubleshooting (1/2)
To avoid all risk of sparks:
– Ensure that any consumers (cour-tesy lights, etc.) are switched off
before disconnecting or reconnect-
ing the battery;
– when charging, stop the charger before connecting or disconnecting
the battery;
– to avoid creating a short circuit be- tween the terminals, do not place
metal objects on the battery;
– always wait at least one minute after the engine has been switched off
before disconnecting a battery;
– make sure that you reconnect the battery terminals after refitting.
Connecting a battery charger
The battery charger must be com-
patible with a battery with nominal
voltage of 12 volts.
Do not disconnect the battery when the
engine is running. Follow the instruc-
tions given by the manufacturer of
the battery charger you are using.
Special procedures may be
required to charge some
batteries. Contact your au-
thorised dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well venti-
lated area.
Risk of serious injury.
Handle the battery with care
as it contains sulphuric acid,
which must not 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. There is a risk of
explosion.
The engine may be hot when car-
rying out operations in close prox-
imity. In addition, the engine cooling
fan can come on at any moment.
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).
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.
Risk of injury.

OPERATING FAULTS (4/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
White smoke from the exhaust. In the diesel version, this is necessar-
ily a fault. Smoke may be caused by
particle filter regeneration. Refer to the information on “Special fea-
tures of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up,
filling” in Section 4).
is slow to go out or remains lit
under acceleration Loss of oil pressure.
Stop the vehicle and contact an approved
Dealer.

5.43
OPERATING FAULTS (5/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating.
Fault with the electric assistance
motor.
Fault in the assistance system. Drive carefully at reduced speed, be aware
of the level of force in the steering wheel
needed to turn the wheels. Consult an ap-
proved dealer
The engine is overheating. The cool-
ant temperature indicator is in the
warning zone and warning light
® comes on. Engine cooling fan not working. Stop the vehicle, switch off the engine and
contact an approved dealer.
Coolant leaks. Check the coolant reservoir: it should con- tain fluid. If there is no coolant, consult an
approved dealer as soon as possible.
Coolant boiling in the coolant reser-
voir. Mechanical fault: damaged cylinder
head gasket. Stop the engine.
Contact an approved dealer.
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 drain\
ing of the cooling
system, it must be refilled with a new mixture prepared in the correct p\
roportions. Reminder: only products approved
by our Technical Department may be used for this purpose.
