Familiarisation

Limit the causes of excess consumption


Spread loads throughout the vehicle; place the heaviest items in the bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.


At the end of winter, remove snow tyres and refit your summer tyres.


Observe the recommendations on
maintenance


Check the tyre pressures regularly, when cold, referring to the label inthe door aperture, driver's side. Carry out this check in par ticular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.


Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) andobser ve the schedule of operations recommended by the manufacturer.


When refuelling, do not continue after the third cut-off of the nozzle toavoid any over flow.


At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settle down toa consistent average.

Safety








Ty r e u n d e r - i nfl ation detection
The system continuously monitors thepressures on the four tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever
y time the tyre pressures are adjusted or a wheel changed. The system triggers an aler t as soon as it
detects a drop in the inflation pressure of one
or more tyres.
The under-inflation detection system does not replace the vigilance or theresponsibility of the driver. This system does not avoid the need tocheck the tyre pressures (including the spare wheel) every month as well as before a long journey. Driving with under-inflated tyres impairsroad holding, extends braking distances and causes premature tyre wear,particularly under arduous condition(high loading, high speed, long journey). S
ystem which automatically checks the pressure of the tyres while driving.

The inflation pressures defined for your vehicle can be found on the tyrepressure label (see the "Identificationmarkings" section). Tyre pressures should be checkedwhen the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderatespeeds). Other wise, add 0.3 bar to the pressures shown on the label.

Driving with under-inflated tyresincreases fuel consumption.

Safety

Under-inflation alert
Reinitialisation
This is given by fixed illumination of
this warning lamp, accompanied byan audible signal and, depending on
equipment, the display of a message.
A label reminds you of the need to reinitialise
the system every time one or more tyre
pressure is adjusted, and after changing one or
more wheels.
)Reduce speed immediately, avoidexcessive steering movements and sudden
braking .)Stop the vehicle as soon as it is safe
to do so.
) In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment),or ) if you have a compressor, such as the one in the temporary puncture repair kit, check
the pressures of the four tyres when cold, or )
if it is not possible to make this check
immediately, drive carefully at reduced speed.



The loss of pressure detected does not always cause visible bulging of the tyre. Do not satisfy yourself with just a visual check. The aler t is maintained until the system is reinitialised.

The tools are installed in the boot under the
floor.
Remove the boot carpet for access to them.

According to equipment.
All of these tools are specific to your
vehicle and can vary according to the level
of equipment. Do not use them for other
purposes. 1. Wheelbrace.
For removing the wheel trim and removingthe wheel bolts. 2.Chocks for immobilising the vehicle (except
versions with manual gearbox). 3.Jack with integral handle.
For raising the vehicle.4. Wheel bolt cover removal tool.
For removing the finishers on the heads of
the wheel bolts on alloy wheels.

Practical information

Ta k i ng out the wheel
)Unscrew the central green screw. )Lift the spare wheel towards you from therear. )Remove the wheel from the boot.


As the spare wheel is narrower than thewheels on the vehicle, in the event of a puncture, the punctured wheel must be carried in the boot.
The spare wheel is located in the boot under
th
e floor.
For access to the spare wheel, refer to the
"Access to the tools" section.











Access to the spare wheel
Putting the spare wheel back inplace
)
Return the wheel to its housing.)
Unscrew the central screw a few turns,
then put it in place in the middle of the
wheel.) Fully tighten the central screw to secure the
wheel correctly.
) Return the box to its position in the middle of the wheel.

and the towing eye 7
arestowed under the left hand boot sill.The other tools, the jack 3
and the tool for removing the wheel bolt head finishers for alloy
wheels 4 , are stowed in a box attached to thespare wheel. The assembly is secured under
the vehicle in a carrier. See the "Access to thespare wheel" section).

Wheel with trim
When removing the wheel
, detach the trimfirst using the wheelbrace 1
pulling at the valvepassage hole.
When refitting the wheel
, refit the trimstarting by placing its notch facing the valve
and press around its edge with the palm of your hand.

Ta k i ng out the spare wheel

The spare wheel is suppor ted by a carrier underneath the vehicle.












Access to the spare wheel *

)
Detach the wheel/box assembly from the
rear of the vehicle.) Remove the hook with its connection plate
to release the wheel/box assembly, asshown in the illustration.) Pull out the wheel to gain access to thebox.
)
Fold the concer tina board and put the left
hand third row seat into position (if your
vehicle has them). ) Raise the pre-cut section of carpet toexpose the nut for operating the spare
wheel carrier.) Using the extension 6 fitted to the end of
the wheelbrace, turn the nut clockwise to
unwind the carrier cable until the spare
wheel reaches the ground. Unwind thelength needed for access to the wheel.
Only a "space-saver" type of spare wheel can be fitted under the vehicle.

272
Practical information

A puncture wheel from the vehiclecannot be fitted under the vehicle. Itmust be carried in the boot. Use a cover to protect the boot.
)Press the tongue, slide the box cover to thecentre and remove it for access to the other
tools (jack and wheel bolt head finisher removal tool for alloy wheels).

Putting the spare wheel back in place
)Stow the corresponding tools in the box and close the cover. )Position the tool box on the ground.


Stowing the tools
)
Return the tools to the box and stow the box in the vehicle's boot. )
Wind in the carrier by turning the
wheelbrace clockwise: once the cable isfully wound in you should no longer feel
any resistance. ) Stow the other tools in the locations provided in the boot.

273

Practical information
) Pass the hook with its connection plate into
the wheel then the box, as illustrated.) Raise the wheel/box assembly underneath
the vehicle by turning the carrier drive nut
anticlockwise using the wheelbrace and
the extension.
) Tighten fully. When the cable is fully wound
in, rotation of the nut no longer presents
any resistance.
Check that the wheel is horizontally flat
against the floor.


)Position the spare wheel on the box so that
the positioning indicator will be introduced
into the bolt hole in the middle of the box.

Practical information
)Place the jack 3 in contact with one of thetwo front Aor rear B
locations provided on
the underbody, whichever is closest to the
wheel to be changed.
) Extend the jack 3
until its base plate is in contact with the ground. Ensure that the centreline of the jack base plate is directly below the location Aor B
used.
)
Raise the vehicle until there is sufficient space between the wheel and the ground
to admit the spare (not punctured) wheel easily.) Remove the bolts and store them in a clean place. )
Remove the wheel.
