Warranty Guide for details of the in-
terval for this operation.
Fluid specifi cation

manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Changing the coolant
The coolant does not have to be

Fluid specifi cation
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
15 minutes.
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. The brake fl uid level should
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 tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
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 allow
the pressure to drop. When the pres-
sure 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 The power steering fl uid
level should be close to the
"MAX" mark. Unscrew the
cap, with the engine cold, to
check the level.
