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.

TYRE PRESSURE (1/2)
Label A
Open the driver’s door to read it.
Tyre pressures should be checked
when the tyres are cold.
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.
A
Vehicle fitted with a tyre pressure
loss warning system
In the event of underinflation (punc-
tures, underinflation etc.), the

warning light on the instrument panel
comes on. Please refer to the informa-
tion on the “Tyre pressure loss warning”
in Section 2.
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 speed rating at least
equal to those of the original
tyres, or conform to those recom-
mended by an 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.

TYRE INFLATION KIT (2/6)
Inflation kit C
Depending on the vehicle, in the event
of a puncture, use inflation kit 1 located
underneath the driver’s seat.
Move the driver’s seat forward and fold
down the seatback to access the infla-
tion kit.
Open it. Screw compressor adapter
3 to con-
tainer 2 and clip onto compressor D.
The bottle must remain in an upright
position.
Unscrew the valve cap on the tyre con-
cerned.
Screw inflation adapter 4 onto the
valve.
Before using this kit, park the vehicle at a sufficient distance from traffic,
switch on the hazard warning lights, apply the handbrake, ask all passen\
-
gers to leave the vehicle and keep them away from traffic.Do not pull out the foreign
body causing the puncture
if it is still in the tyre.

TYRE INFLATION KIT (5/6)
Inflation kit E
Depending on the vehicle, in the event
of a puncture, use the inflation kit lo-
cated underneath the driver’s seat.
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.
With the engine running and the
parking brake applied,
– unroll the hose from the container;
– connect the compressor hose 14 to the container’s inlet 19;
– depending on the vehicle, connect the container 19 to the compressor
from the container recess 18;
– unscrew the valve cap on the rel- evant wheel and screw on the con-
tainer’s inflation adapter 12;
– disconnect any accessories previ- ously connected to the vehicle’s ac-
cessories sockets;
– adapter 13 must be connected to
the vehicle accessories socket;
– press switch 15 to inflate the tyre to
the recommended pressure (please
refer to the information in the section
on “Tyre pressure”);

– after a maximum of 15 minutes, stop inflating and read the pressure (on
pressure gauge 16).
Note: while the bottle is empty-
ing (approximately 30 seconds),
the pressure gauge 16 will indicate
briefly a pressure of up to 6 bars,
then the pressure drops.
– adjust the pressure: to increase it, continue inflation with the kit; to
reduce it, press button 17.
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.

If you use anti-theft bolts, fit these
nearest the valve (otherwise it may
not be possible to fit the wheel trim).

your vehicle’s presence
with a warning triangle or with other
devices as per the legislation ap-
plying to the country you are in.

To prevent any risk of injury
or damage to the vehi-
cle, raise the jack until the
wheel you are replacing is
a maximum of 3 centimetres off the
ground.
If necessary, remove the wheel trim.
Use the wheelbrace 2 to slacken off the
wheel bolts. Position it so as to be able
to push from above.Vehicle equipped with a jack with a
heightener

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).
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.
Pressures should be checked when the
tyres are cold; ignore higher pressures
which may be reached in hot weather
or following a fast journey.
If tyre pressures cannot be checked
when the tyres are cold, the normal
pressures must be increased by 0.2 to
0.3 bar (or 3 PSI).
Never deflate a hot tyre.
Dual wheel versions
To inflate the outer wheel, it is recom-
mended that the inflation tube is passed
between the two wheels. Vehicle fitted with a tyre pressure
loss warning system
If underinflated (puncture, low pres-
sure, etc.), the warning light
 on
the instrument panel comes on, see
“Tyre pressure loss warning system” in
Section 2.
Changing wheels around
This practice is not recommended.
Emergency spare wheel
Refer to the information on the
“Emergency spare wheel” and
“Changing a wheel” in Section 5.
