STOP & START
The Stop & Start system puts the en-
gine temporarily on standby - STOP
m o d e - d u r i n g s t o p s i n t h e t r a f fi c
( r e d l i g h t s , t r a f fi c j a m s , o r o t h e r . . . ) .
The engine restarts automatically -
START mode - as soon as you want
to move off. The restart takes place
instantly, quickly and silently.
Perfect for urban use, the Stop &
Start system reduces fuel consump-
tion and exhaust emissions as well
as the noise level when stationary.
Operation
Going into engine STOP mode The "ECO" warning lamp
comes on in the instrument
panel and the engine goes
into standby:
- with the 6-speed electronic
gearbox system , at speeds be-
l o w 4 m p h ( 6 k m / h ) , p r e s s t h e
brake pedal or put the selector
lever in position N . I f y o u r v e h i c l e i s fi t t e d w i t h t h e s y s -
tem, a time counter calculates the
sum of the periods in STOP mode
d u r i n g a j o u r n e y . I t r e s t s i t s e l f t o z e r o
every time the ignition is switched on
with the key.
Special cases: STOP mode
unavailable
Never refuel with the en-
gine in STOP mode; you
must switch off the ignition
with the key.
For your comfort, during parking
maoeuvres, STOP mode is not avail-
able for a few seconds after coming
out of reverse gear.
STOP mode does not affect the func-
tionality of the vehicle, such as for
example, braking, power steering...
STOP mode is not invoked
when:
- the driver's door is open,
- the driver's seat belt is not fas- tened,
- the vehicle has not exceeded 6 m p h ( 1 0 k m / h ) s i n c e t h e l a s t
engine start using the key,
- the electric parking brake is ap- plied or being applied,
- the engine is needed to maintain a comfortable temperature in the
passenger compartment,
- demisting is active,
- some special conditions (battery charge, engine temperature,
braking assistance, ambient
t e m p e r a t u r e . . . ) w h e r e t h e e n g i n e
is needed to assure control of a
system.
In this case, the "ECO" warning
l a m p fl a s h e s f o r a f e w s e c o n d s t h e n
goes off.
This operation is perfectly normal.

The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.

Coolant level
Changing the coolant
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
1 5 m i n u t e s .
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick. T h e b r a k e fl u i d l e v e l s h o u l d
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is
regulated by the fan. This can oper-
ate with the ignition off.

gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited. When working under the
bonnet, take care, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fluid level T h e p o w e r s t e e r i n g fl u i d
level should be close to the
"MAX" mark. Unscrew the
cap, with the engine cold, to
check the level.
