Refer to the Maintenance Document for
your vehicle.
Checking intervals
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.
LEVELS (1/3)
 Coolant
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MIN mark.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
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).

LEVELS (2/3)
 Brake fluid
This should be checked frequently, and
any time you notice even the slightest
loss in braking efficiency.
The level should be read with the engine
switched off and on level ground.Level 2
It is normal for the level to drop as
the linings become worn, but it should
never drop below the “MINI” warning
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. Topping up
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).

Battery 1 does not require any mainte-
nance. You should not open it or add
any fluid.
Handle the battery with care
as it contains sulphuric acid
which must not come into
contact with the 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.
Depending on the vehicle, a system
continuously checks the battery charge
status. If this decreases, the message
“Battery low start engine” is displayed
on the instrument panel. In this case,
start the engine and the message on
the instrument panel will disappear.
The charge status of your battery can
decrease especially if you use your ve-
hicle:
– for short journeys;
– for driving in town;
– when the temperature drops;
– after extended use of energy-con- suming devices (radio, etc.) with the
engine switched off.
Please note when work-
ing close to the engine that
it may be hot. In addition,

12 VOLT 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.

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) and that the discharged
battery is properly connected. Switch
off your vehicle ignition.
Start the engine of the vehicle supply-
ing the current and run it at a moderate
speed.

Refitting
Offer up the blade 3 of the wiper arm 1
at an angle of 30°.
Slide the blade along the arm until
it clips on. Check that it is correctly
locked in place. Lower the windscreen
wiper arm carefully.
With the ignition on, return the wind-
screen wiper stalk to the stop position.
The blade on the driver’s side must
always be above the passenger blade.
If this is not the case, a quick sweep of
the windscreen wipers should be per-
formed once the vehicle is travelling at
over 4 mph (7 km/h).– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating or damaging the
blades).
– Check the condition of the wiper
blades.
Replace the wiper blades as soon
as they begin to lose efficiency
(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.
Note: before restarting your vehicle,
lower the windscreen wiper blades
onto the windscreen to avoid any risk
of damaging the bonnet or the wipers.
