Practical information

1. Screenwash fluid reservoir.

2. Engine coolant reservoir.

3. Brake fluid reservoir.

4. Battery/Fuses.

Engine oil level

The liquid must comply with the

manufacturer's recommendations and with

the vehicle's engine.

The check is carried out either when

the ignition is switched on using the oil

level indicator in the instrument panel

for vehicles equipped with an electric

gauge, or using the dipstick.

5. Fusebox.

Take care when working under the bonnet,

as certain areas of the engine may be

extremely hot (risk of burns) and the

cooling fan could start at any time (even

with the ignition off).

6. Air filter.

7. Engine oil dipstick.

8. Engine oil filler cap.

9. Remote earth point.

10. Priming pump*

To ensure that the reading is correct, your

vehicle must be parked on a level surface

with the engine stopped for more than

30 minutes.

Depending on engine.

It is normal to top up the oil level between

two services (or oil changes). PEUGEOT

recommends that you check the level, and top

up if necessary, every 3,000 miles (5,000 km).

Used products

The Diesel circuit is under very high

pressure.

All work on this circuit must be carried out

only by a PEUGEOT dealer or a qualified

workshop.

Avoid prolonged contact of used oil or

fluids with the skin.

Most of these fluids are harmful to health

or indeed very corrosive.

Checking using the dipstick

The location of the dipstick is shown in the

corresponding underbonnet layout view.

F Take the dipstick by its coloured grip and

pull it out completely.

Do not discard used oil or fluids into

sewers or onto the ground.

Checking levels

F Wipe the end of the dipstick using a clean

non-fluffy cloth.

F Refit the dipstick and push fully down, then

pull it out again to make the visual check:

the correct level is between marks A and B.

Check all of these levels regularly, in line with

the manufacturer's service schedule. Top them

up if necessary, unless otherwise indicated.

If a level drops significantly, have the

corresponding system checked by a PEUGEOT

dealer or a qualified workshop.

Take used oil to a PEUGEOT dealer or

a qualified workshop and dispose of it in

the containers reserved for this purpose.

184

Practical information

The brake fluid level must be between

the marking "A" (MAX located on the

remote reservoir) and the marking "B"

(MIN located on the main reservoir). If

it is not, check the brake pad wear.

F Add oil in small quantities, avoiding any

spills on engine components (risk of fire).

F Wait a few minutes before checking the

level again using the dipstick.

F Add more oil if necessary.

A = MAX

B = MIN

F After checking the level, carefully refit the oil

filler cap and the dipstick in its tube.

Changing the ﬂuid

Refer to the personalised service schedule for

your vehicle.

If you find that the level is above the A mark or

below the B mark, do not start the engine.

After topping up the oil, the check when

switching on the ignition with the oil level

indicator in the instrument panel is not

valid during the 30 minutes after topping

up.

Fluid speciﬁcation

This fluid must conform to the manufacturer's

recommendations.

If the level is above the MAX mark (risk of

damage to the engine), contact a PEUGEOT

dealer or a qualified workshop.

If the level is below the MIN mark, you must

top up the engine oil.

Coolant level

Engine oil change

Check the coolant level regularly.

It is normal to top up this fluid

between two services.

Oil grade

In order to maintain the reliability of the engine

and emissions control system, never use

additives in the engine oil.

Before topping up the oil or changing the oil,

check that the oil is the correct grade for your

engine and conforms to the manufacturer's

recommendations.

The check and top-up must only be done with

the engine cold.

Brake fluid level

A low coolant level presents a risk of serious

damage to your engine.

The coolant level should be close to the "MAX"

mark but should never exceed it.

If the level is close to or below the "MIN" mark,

it is essential to top up.

Topping up the engine oil level

The location of the oil filler cap is shown in the

corresponding underbonnet layout view.

F Unscrew the oil filler cap to access the filler

opening.

185

Practical information

When the engine is hot, the temperature of this

fluid 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 to the required level.

12 V battery

In wintry conditions, it is recommended

that you use an ethyl alcohol or methanol

based fluid.

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.

Diesel fuel additive level

(Diesel with particle filter)

For more information on the precautions

to take before starting work on the 12 V

battery, refer to the corresponding

section.

A low additive level is indicated by

illumination of this warning lamp,

accompanied by an audible warning

and a message in the instrument

panel screen.

Fluid speciﬁcation

This fluid must conform to the manufacturer's

recommendations.

Versions equipped with Stop & Start are

fitted with a 12 V lead-acid battery of

specific technology and specification.

Its replacement should be carried out

only by a PEUGEOT dealer or a qualified

workshop.

Topping up

The cooling fan may start after

switching off the engine: take care

with articles and clothing that might be

caught by the fan blades.

This additive must be topped up without delay

by a PEUGEOT dealer or a qualified workshop.

Checks

Unless otherwise indicated, check these

components in accordance with the

manufacturer's service schedule and according

to your engine.

Screenwash fluid level

Air filter

Depending on the environment

(e.g. dusty atmosphere) and the

use of the vehicle (e.g. city driving),

replace it twice as often if

necessary.

Top up to the required level when

necessary.

Otherwise, have them checked by a PEUGEOT

dealer or a qualified workshop.

Fluid speciﬁcation

For optimum cleaning and to avoid freezing,

this fluid must not be topped up or replaced

with plain water.
