Coolant level
The check and top-up must only be done with 
the engine cold.
A low coolant level presents a risk of serious 
damage to your engine.
The coolant level should be close to the "MA X" 
mark but should never exceed it.
If the level is close to or below the "MIN" mark, 
it is essential to top-up.
When the engine is hot, the temperature of the 
coolant is regulated by the fan.
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 the risk of scalding when you need to 
top-up in an emergency, place a cloth around 
the cap and unscrew the cap by two turns to 
allow the pressure to drop.
Once the pressure has dropped, remove the 
cap and top-up the level.Check the coolant level regularly.
It is normal to top up the fluid 
between two services.
Fluid specification
The fluid must conform to the manufacturer's 
recommendations.
The cooling fan may star t after 
switching off the engine: take care 
with articles and clothing that might be 
caught by the fan blades.
Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid freezing, 
this fluid must not be topped up or replaced 
with plain water.
In wintry conditions, it is recommended that you 
use an ethyl alcohol or methanol based fluid.
Diesel additive level (Diesel 
engine with particle filter)
A low additive level is indicated by illumination 
of the service warning light, accompanied by an 
audible warning and a message in the screen 
(if a display screen is fitted).
To p p i n g  u p
This additive must be topped-up by a 
PEUGEOT  dealer or a qualified workshop 
without delay.
Used products
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 into 
sewers or onto the ground.
Take used oil to a PEUGEOT  dealer or 
a qualified workshop and dispose of in 
the containers made available for this 
purpose.

Checks
Unless otherwise indicated, check these components in accordance with the manufacturer's 
service schedule and according to your engine.
Other wise, have them checked by a PEUGEOT dealer or a qualified workshop.
12 V battery
For more information and the precautions to 
take before starting work on the 12 V batter y, 
refer to the corresponding section. The battery does not require any 
maintenance.
However, check regularly that the 
terminals are correctly tightened 
(versions without quick release 
terminals) and that the connections 
are clean.
Air filter and passenger compartment filter
Depending on the environment (e.g. dusty 
atmosphere) and the use of the vehicle (e.g. 
city driving), replace them twice as often if 
necessary
.
A clogged passenger compartment filter may 
have an adverse effect on the per formance 
of the air conditioning system and generate 
undesirable odours. Refer to the manufacturer's 
service schedule for details of the 
replacement intervals for these 
components.
Oil filter
Replace the oil filter each time the 
engine oil is changed.
Refer to the manufacturer's 
service schedule for details of 
the replacement interval for this 
component.
Particle filter (Diesel)
As soon as the traffic conditions permit, 
regenerate the filter by driving at a speed of at 
least 40 mph (60 km/h) until the warning light 
goes off.
If the warning light stays on, this indicates a low 
additive level; refer to “Diesel additive level” 
section.
or 
The start of saturation of the particle 
filter is indicated by the fixed 
illumination of this warning light 
accompanied by a warning message 
in the screen (if a display screen is 
fitted).
On a new vehicle, the first particle 
filter regeneration operations may be 
accompanied by a "burning" smell, which 
is per fectly normal.
Following prolonged operation of the 
vehicle at very low speed or at idle, 
you may, in exceptional circumstances, 
notice the emission of water vapour at the 
exhaust on acceleration. This does not 
affect the behaviour of the vehicle or the 
environment.
