DRIVING SAFELY
Electric parking brake
Manual application/release
Automatic application/release
Before leaving the ve-
hicle, check that the
brake warning lamp in
the instrument panel
and the P
warning lamp in the control
lever A
are on fi xed (not fl ashing)
.
Manual application
of the parking
brake is possible by pulling
the control
lever A
.
With the ignition on, manual release
of
the parking brake is possible by press-
ing the brake pedal
and pulling then
releasing
the control lever A
. Press the accelerator pedal and let the
clutch pedal up (manual gearbox), the
parking brake is released automatically
and progressively as you move off.
With the vehicle at rest, on switching off
the engine the parking brake is applied
automatically.
147
With the engine running, on
opening the driver's door there
is an audible warning; apply the
parking brake manually.
Do not leave a child alone inside
the vehicle with the ignition on;
they might release the parking
brake. If you are towing a trailer or car-
avan or if the slope might vary
(transport on a ferry, lorry, tow-
ing...) make a maximum manual
application with a long pull on
the control lever A
to immobilise
the vehicle. If this warning lamp is on in the
instrument panel, the automat-
ic application/release
is de-
activated
; apply and release
the parking brake manually.

Switch off the headlamps and front
foglamps when the level of light does
not require their use.
Avoid running the engine before mov-
ing off, particularly in winter; your ve-
hicle will warm up much faster while
driving.
As a passenger, if you avoid connect-
ing your multimedia devices (fi lm, mu-
sic, video game...), you will contribute
towards limiting the consumption of
electrical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.
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 refi t your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly,
when cold, referring to the label in the
door aperture, driver's side.
Carry out this check in particular:
- 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 serviced regularly
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.
When refuelling, do not continue after
the 3 rd cut-off of the nozzle to avoid
any overfl ow.
At the wheel of your new vehicle,
it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see
the fuel consumption settle down to a
consistent average.
