ENGINE OIL LEVEL: topping up, filling (3/3)/OIL CHANGE
Engine oil change: if you
are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.
Filling: take care when
topping up the oil that
no oil drips onto engine
components - risk of fire.
Remember to refit the cap securely
as there is a risk of fire if oil splashes
onto hot engine components.
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Oil change
Service interval: refer to the
Maintenance Document for your vehi-
cle.
Engine oil grade
Refer to the maintenance document for
your vehicle.
Oil change capacity
Please refer to the maintenance docu-
ment for your vehicle, or contact an au-
thorised dealer.
Always check the engine oil level using
the dipstick, as explained previously (it
should never fall below the minimum
level, or be over the maximum level on
the dipstick).

The engine may be hot
when carrying out opera-
tions in close proximity. 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 by pressing
the engine stop button (please see
the information on “Starting, stop-
ping the engine” in Section 2).

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 MINI mark. 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 coo- ling system.
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.

LEVELS (2/3)
Brake fluid level
The level should be read with the engine
switched off and on level ground. This
should be checked frequently, and any
time you notice even the slightest loss
in braking efficiency. 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).
Replacement intervals
Refer to the Maintenance Document for
your vehicle.

The battery 1 does not require any
maintenance.Label A
Observe the indications on the battery:
– 2 naked flames and smoking are for-
bidden;
– 3 eye protection required;
– 4 keep away from children;
– 5 explosive materials;
– 6 refer to the handbook;
– 7 corrosive materials.
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.
BATTERY (1/2)
Depending on the vehicle, a system
continuously checks the battery charge
status. If the level drops, the message
“Battery low start engine” is displayed
on the instrument panel. In this case,
start the engine. Then the message
“Battery charging” appears on the in-
strument panel for the duration of the
charging time.
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 consumers (radio etc.) with the engine switched
off.

Depending on the vehicle, remove the
central partition in the storage compart-
ment to access the inflation kit.
Open the kit, remove caps 1 and 3 (the
cap must not be removed from the
bottle) then screw bottle 2 to its base 3.
Engine running, handbrake applied:
– unscrew the valve cap on the wheel concerned and screw inflation
adapter 6 onto the valve;
– connect adapter 8 to the accessories
socket on the dashboard of the vehi-
cle;
– press switch 5 to inflate the tyre to
the recommended pressure (check
the label affixed to the edge of the
driver’s door);
– after a maximum of 5 minutes, stop inflating and read the pressure (on
pressure gauge 4);
Note: while the bottle is emptying
(approximately 30 seconds), pres-
sure gauge 4 will briefly indicate a
pressure of 6 bar, then the pressure
will drop.

2– adjust the pressure: to increase it, continue inflating with the kit, to
reduce it, turn button 7 located on
the inflation adapter.
If a minimum pressure of 1.8 bar is
not reached after 15 minutes, repair
is not possible; do not drive the ve-
hicle but contact an approved dealer.
Inflation kit C
Depending on the vehicle, in the event
of a puncture, use the kit located under-
neath the boot carpet.
Before using this kit, park
the vehicle at a sufficient
distance from traffic, switch
on the hazard warning
lights, apply the handbrake, ask all
passengers to leave the vehicle and
keep them away from traffic.
If the vehicle is parked on
the hard shoulder, you must
warn other road users of
your vehicle’s presence
with a warning triangle or with other
devices as per the legislation apply-
ing to the country you are in.

Connect the positive cable A to the
support 1 on the (+) terminal, then to
the (+) terminal 2 of the battery sup-
plying the current.
Connect the negative cable B to the (–)
terminal 3 of the battery supplying the
current and then to the (–) terminal 4 of
the discharged battery.
Start the engine, and as soon as it starts
running, disconnect cables A and B in
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) 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 an interme-
diate engine speed.
BATTERY: troubleshooting (2/2)
Check that there is no con-
tact between leads A and B
and that the positive lead A
is not touching any metal
parts on the vehicle supplying the
current.
Risk of injury and/or damage to the
vehicle.

WINDSCREEN WIPER BLADES
Replacing windscreen wiper
blades 1
With the ignition on and engine
switched off, lower the windscreen
wiper stalk completely: they stop
slightly away from the bonnet.
Lift wiper arm 3, pull tab 2 (move-
ment A) and push the blade upwards.
To refit
Slide the blade along the arm until it
clips on. Make sure that the blade is
correctly locked in position. Return the
windscreen wiper stalk to the park po-
sition.

Check the condition of the wiper
blades. You are responsible for their
service life:
– clean the blades, windscreen and rear screen regularly with soapy
water;
– do not use them when the wind- screen or rear screen are dry;
– free them from the windscreen or rear screen when they have not
been used for a long time.

– Lift wiper arm 6;
– pivot blade 4 until some resistance is
met (movement C);
– depending on the vehicle, press tab 5, then remove the blade by pull-
ing it (movement B).

– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating).
– 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.

OPERATING FAULTS (3/6)
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. Please refer to the information on “Special
features 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.
