BONNET
Protects the components of the engine
and provides access for checking levels.
Opening
Push the exterior safety catch B to
the left and raise the bonnet.
Unclip the bonnet stay C from its
housing, holding it by its foam pro-
tection.
Fix the stay in the notch to hold the
bonnet open.
The location of the interior re-
lease lever prevents opening of
the bonnet while the front left
door is closed.
Closing
Take the stay out of the support
notch.
Clip the stay in its housing.
Lower the bonnet and release it at
the end of its travel.
Pull on the bonnet to check that it is
fully latched.

CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.

shop.
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or us-
ing the dipstick.
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil grade
The oil must be suitable for your engine
and conform to the manufacturer's rec-
ommendations. Brake fluid level
T h e b r a k e fl u i d l e v e l s h o u l d b e
close to the "MAX" mark. If it is
not, check the brake pad wear.

manufacturer's recommendations and
meet the DOT4 standard.
Coolant level 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 operate with the ig-
nition off.

o f f , e v e n i f t h e e n g i n e i s c o l d .
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, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the 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 manu-
facturer's recommendations.
Screenwash fluid level
Top up the level when neces-
sary.
