Practical information

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.

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.

Fluid specification

The fluid must be topped up with a pre-mixed

product.

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).

Brake fluid

The level of this fluid should be close to

the "MAX" mark. If not, check the brake

pads for wear.

Once the pressure has dropped, remove the cap

and top up to the required level.

Filling with pure water is prohibited in

all circumstances (risk of freezing,

limescale, etc.).

For electric versions

To know how often the brake fluid should be

replaced, refer to the manufacturer's servicing

schedule.

Do not top up the coolant.

Clean the cap before removing it to

refill. Use only DOT4 brake fluid from a

sealed container.

Checks

Unless otherwise indicated, check these

components in accordance with the

Manufacturer's service schedule and according

to your engine.

If the level is close to or below

the "MIN" mark, it is essential to contact a

CITROËN dealer or a qualified workshop.

Engine coolant

For petrol or hybrid versions

It is normal to top up this fluid between

two services.

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.

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

it is essential to top it up.

Otherwise, have them checked by a CITROËN

dealer or a qualified workshop.

Only use products recommended by

CITROËN or products of equivalent

quality and specification.

In order to optimise the operation of

components as important as those in the

braking system, CITROËN selects and offers

very specific products.

Cooling of the engine when stopped

The engine cooling fan may start

after the engine has been switched off.

Take care with objects or clothing that

could be caught in the blades of the fan!

Screenwash fluid

Top up to the required level when

necessary.

When the engine is hot, the temperature of the

coolant is regulated by the fan.

use of the vehicle (e.g. dusty

atmosphere, city driving), change it twice as

often, if necessary.

Check regularly that the terminals are correctly

tightened (versions without quick-release

terminals) and that the connections are clean.

Brake disc wear

For information on checking brake disc

wear, contact a CITROËN dealer or a

qualified workshop.

Oil filter

For more information on the

precautions to take before any work

on the 12 V battery, refer to the

corresponding section.

Change the oil filter each time the

engine oil is changed.

Manual parking brake

If you notice excessive brake lever travel

or decreased effectiveness, the parking

brake must be adjusted, even between two

services.

Manual gearbox

The gearbox does not require any

maintenance (no oil change).

Versions equipped with Stop & Start

This system does not require any routine

problem, do not hesitate to have the system

workshop.

atmosphere, city driving), change it twice as

often, if necessary.

For more information on the Electric

parking brake, refer to the

A clogged passenger compartment

filter can adversely affect air

conditioning system performance and

generate undesirable odours.

Wheels and tyres

After washing the vehicle, moisture, or

in wintry conditions, ice can form on

the brake discs and pads: braking efficiency

The inflation pressure of all tyres,

including the spare wheel, must be

checked on "cold" tyres.

140

Practical information

The pressures 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.

Winter or 4-seasons tyres can be

identified by this symbol on their

sidewalls.

►ꢀ put the automatic gearbox or drive selector

in N mode.

►ꢀ manually release the electric parking brake.

When the vehicle is fitted with an

automatic gearbox or a drive selector,

it is strongly recommended to stay inside

the vehicle when it is in free-wheeling mode.

Timing and accessory kits

The timing and accessory kits are used

from the time the engine is started until

it is switched off. It is normal for them to wear

over time.

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!

A faulty timing or accessory kit can damage

the engine, rendering it unusable. Observe the

recommended replacement frequency, stated

in distance travelled or time elapsed, whichever

is reached first.

With manual or EAT6

automatic gearbox and

manual parking brake

Driving with worn or damaged tyres reduces

the braking and road holding performance of

the vehicle. Regularly check the condition of

the tyres (tread and sidewalls) and rims as well

as the presence of the valve caps.

When the wear indicators no longer appear set

back from the tread, the depth of the grooves

is less than 1.6 mm; replace the tyres as soon as

possible.

Using different size wheels and tyres from

those specified can affect the lifetime of

tyres, wheel rotation, ground clearance, the

speedometer reading and have an adverse

effect on road holding.

Fitting different tyres on the front and rear

axles can cause the ESC to mistime.

Free-wheeling

In certain situations, it is necessary to put the

vehicle into free-wheeling mode (e.g. towing, on

a rolling road, automatic car wash (Wash mode),

rail or sea transport).

To release them

►ꢀ With the vehicle stationary and engine

running, depress the brake pedal.

►ꢀ With a manual gearbox, place the gear lever

into neutral.

►ꢀ With an automatic gearbox, place the gear

selector to mode N.

►ꢀ Release the parking brake.

►ꢀ Release the brake pedal, then switch off the

engine.

The procedure varies according to the type of

gearbox and parking brake.

Never leave the vehicle unattended

with the vehicle into free-wheeling

mode.

Recommendations

Always mark the direction of rotation on the

tyres that will be stored when fitting winter or

summer tyres. Store them in a cool, dry place

and away from direct exposure to the sun's rays.

Reverting to normal operation

►ꢀ Apply the parking brake.

►ꢀ With an automatic gearbox, place the gear

selector to mode P.

To be able to move the vehicle in free-

wheeling mode, the driver absolutely must :

►ꢀ leave the engine running.
