Practical information  
Topping up the engine oil level  
For the location of the engine oil filler cap,  
please refer to the corresponding engine  
compartment illustration.  
In winter (temperatures below zero), a fluid  
containing an anti-freeze agent which is  
appropriate for the temperature conditions must  
be used in order to protect the system's  
components (pump, tank, ducts, jets).  
Clean the cap before removing it to  
refill.Use only DOT4 brake fluid from a  
sealed container.  
Never remove the oil filler cap with  
the engine running. Risk of burns and  
splashes inside the engine compartment.  
Engine coolant  
Filling with pure water is prohibited in all  
circumstances (risk of freezing, limescale,  
etc.).  
It is normal to top up this fluid  
between two services.  
Add oil in small quantities, avoiding any spills  
on engine components (risk of fire).  
The check and top-up must only be done with  
the engine cold.  
A level of coolant that is too low risks causing  
major damage to the engine; the coolant level  
must be close to the "MAX" mark without ever  
going above it.  
Checks  
Unless otherwise indicated, check these  
components in accordance with the  
Manufacturer's service schedule and according  
to your engine.  
Wait a few minutes before checking the level  
again using the dipstick.  
Top up the level if necessary.  
After checking the level, carefully screw the  
oil filler cap back on and push the dipstick  
back into its tube up to the stop.  
Otherwise, have them checked by a PEUGEOT  
dealer or a qualified workshop.  
If the level is close to or below the "MIN" mark, it  
is essential to top it up.  
The dipstick must be pushed completely in  
to prevent oil from spilling onto the engine.  
Risk of fire inside the engine compartment.  
When the engine is hot, the temperature of the  
coolant is regulated by the fan.  
As the cooling system is pressurised, wait at  
least one hour after switching off the engine  
before carrying out any work.  
In order to avoid the risk of scalding if you need  
to top up in an emergency, wrap a cloth around  
the cap and unscrew the cap by two turns to  
allow the pressure to drop.  
Only use products recommended by  
PEUGEOT or products of equivalent  
quality and specification.  
In order to optimise the operation of  
components as important as those in the  
braking system, PEUGEOT selects and offers  
very specific products.  
The oil level indication displayed on the  
instrument panel when the ignition is  
switched on is not valid for 30 minutes  
following an addition of oil.  
Once the pressure has dropped, remove the cap  
and top up to the required level.  
12 V battery  
Brake fluid  
The battery does not require any  
maintenance.  
The level of this fluid should be close  
to the "MAX" mark. If not, check the  
brake pads for wear.  
Screenwash fluid  
Top up to the required level when  
necessary.  
Check regularly that the terminals are  
correctly tightened (versions without quick-  
release terminals) and that the connections are  
clean.  
To know how often the brake fluid should be  
replaced, refer to the manufacturer's servicing  
schedule.  
Fluid specification  
The fluid must be topped up with a pre-mixed  
product.

The gearbox does not require any  
maintenance (no oil change).  
For more information on the Electric  
parking brake, refer to the corresponding  
section.  
Versions equipped with Stop & Start are  
fitted with a 12 V lead-acid battery with  
special technology and specifications.  
Its replacement should be carried out only by  
a PEUGEOT dealer or a qualified workshop.  
Brake pads  
Wheels and tyres  
Brake wear depends on the style  
of driving, particularly in the case  
of vehicles used in town, over short  
distances. It may be necessary to  
have the condition of the brakes  
checked, even between vehicle  
services.  
The inflation pressure of all tyres,  
including the spare wheel, must be  
checked on "cold" tyres.The pressures  
Passenger compartment  
filter  
Depending on the environment and  
the use of the vehicle (e.g. dusty  
atmosphere, city driving), change it  
twice as often, if necessary.  
Unless there is a leak in the circuit, a drop in  
the brake fluid level indicates that the brake pads  
are worn.  
After washing the vehicle, moisture, or  
in wintry conditions, ice can form on the  
brake discs and pads: braking efficiency may  
be reduced. Gently dab the brakes to dry and  
defrost them.  
A clogged passenger compartment filter  
can adversely affect air conditioning  
system performance and generate  
undesirable odours.  
indicated on the tyre pressure label are valid for  
"cold" tyres. If you have driven for more than 10  
minutes or more than 6 miles (10 kilometres) at  
over 31 mph (50 km/h), add 0.3 bar (30 kPa) to  
the values indicated on the label.  
Air filter  
Brake disc wear  
Depending on the environment and  
the use of the vehicle (e.g. dusty  
atmosphere, city driving), change it  
twice as often, if necessary.  
For any information on checking  
brake disc/drum wear, contact a  
PEUGEOT dealer or a qualified  
workshop.  
Under-inflation increases energy  
consumption. Non-compliant tyre  
pressures cause tyres to wear prematurely  
and have an adverse effect on the vehicle's  
road holding - risk of accident!  
Oil filter  
Electric parking brake  
Change the oil filter each time the  
engine oil is changed.  
This system does not require any  
routine servicing. However, in the  
event of a problem, do not hesitate  
to have the system checked by  
Driving with worn or damaged tyres reduces the  
braking and road holding performance of the  
vehicle. Regularly check the condition of the
