Checks






Checking levels






Before doing anything under the bonnet,
switch off the ignition (Ready
lamp off) to avoid any risk of injury resulting fromautomatic operation of the engine.
Oil level
The check is carried out either when
the ignition is switched on using the oil level indicator on the instrumentpanel, or using the dipstick.
This manual check will only be correct if the
vehicle is on level ground and the engine has been off for more than 30 minutes.
It is normal to top up the oil level between
two ser vices (or oil changes). PEUGEOT
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms).
After topping up the oil, the check when switching on the ignition with the oil levelindicator in the instrument panel is not validduring the 30 minutes after topping up.
Engine oil change

Refer to the ser vicing booklet for details of
the inter val 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 specifi cation
The oil must be the correct grade for your
engine and conform to the manufacturer'srecommendations.

Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Refer to the ser vicing booklet for details of
the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT4 standard.

Power steering fluid level

The power steering fluid level shouldbe close to the "MA X" mark. With
the engine cold, unscrew the cap tocheck the level.
If a level drops si
gnificantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
Take care when working under the
bonnet, as certain areas of the engine may be extremely hot (risk of burns).

220
Checks
The coolant level should be closeto the "MA X" 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 ignition off.
On vehicles which are fitted with a par ticle
emission filter, 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 theengine before carrying out any work.
To avoid any risk of scalding, unscrew the cap
b
y two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top up t
he level.

Changing the coolant
The coolant does not have to be changed.


Fluid specifi cation

The coolant must conform to the
manufacturer's recommendations.


Fluid specifi cation

For optimum cleaning and to avoid freezing,
this fluid must not be topped up with or
replaced with plain water.
Screenwash and headlamp
wash fluid
In the case of vehicles fitted withheadlamp washers, the low fluid levelis indicated by an audible signal anda message in the instrument panelscreen.
Top up the reser voir when you next stop the
vehicle.

Checks
Avoid prolonged contact of used oil or fluids with the skin. Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids intosewers or onto the ground. Take used oil to a PEUGEOT dealer or a qualified workshop (France) or to an authorised waste disposal site.

emission filter)
A low additive level is indicated by illumination
of the ser vice warning lamp, accompanied by an audible warning and a message in the
instrument panel screen.

Checks






Checks
12 V battery

The battery does not require any
maintenance.

However, check that the terminals
are clean and correctl
y tightened,
particularly in summer and winter.
When carrying out work on the battery, refer to
the "Practical information" section for details of
the precautions to be taken before disconnectingthe battery and following its reconnection. Refer to the servicin

details of the replacement inter vals
for these components.
Dependin
g on the environment (e.g.
dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary.y A clogged passenger compar tment filter mayhave an adverse effect on the performance
of the air conditioning system and generate undesirable odours.

Air filter and passenger compartment filter
Replace the oil filter each time
the engine oil is changed.
Refer to the servicing booklet for
details of the replacement inter val
for this component.
Oil filter
The presence of this label, in particular with
the Stop & Star t system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a PEUGEOT dealer or a qualified workshopis essential when replacing or disconnectingthe battery. Unless other wise indicated, check these components in accordance with the ser vicing booklet and according to your engine.
Other wise, have them checked by a PEUGEOT dealer or a qualified workshop.
