Hill start assist

System which keeps your vehicle immobilised

temporarily (approximately 2 seconds) when

starting on a gradient, the time it takes to

move your foot from the brake pedal to the

accelerator pedal.

Operation

This function is only active when:

-

the vehicle is completely stationary, with

your foot on the brake pedal,

-

when certain conditions of gradient are met,

with the driver’s door closed.

The hill start assist function cannot be

deactivated.

On an ascending slope, with the vehicle

stationary, the vehicle is held for a brief

moment when you release the brake pedal.

On a descending slope, with the vehicle

stationary and reverse gear engaged, the

vehicle is held for a brief moment when you

release the brake pedal.

Do not leave the vehicle while it is

being held in the hill start assist phase.

If you need to leave the vehicle while

the engine is running, apply the parking

brake manually then ensure that the

parking brake warning lamp is on (not

flashing) in the instrument panel.

-

With a manual gearbox, if you are in first

gear or neutral.

-

With an automatic gearbox, if you are in

position D or M.

Operating fault

If a fault occurs with the system, these warning

lamps come on. Contact a CITROËN dealer

or a qualified workshop to have the system

checked.

Gear efﬁciency indicator*

System which reduces fuel consumption by recommending the most appropriate gear.

Operation

Depending on the driving situation and your

vehicle's equipment, the system may advise

you to skip one (or more) gear(s). You can

follow this instruction without engaging the

intermediate gears.

The gear engagement recommendations must

not be considered compulsory. Indeed, the

configuration of the road, the amount of traffic

and safety remain determining factors when

choosing the best gear. Therefore, the driver

remains responsible for deciding whether or not

to follow the advice given by the system.

This function cannot be deactivated.

The information appears in the instrument

panel in the form of an arrow.

Example:

-

You are in third gear.

You press the accelerator pedal.

On vehicle fitted with a manual

gearbox, the arrow may be

accompanied by the gear

recommended.

-

The system may suggest that you engage

a higher gear.

With an automatic gearbox, the system

is only active in manual mode.

The system adapts its gear change

recommendation according to the

driving conditions (slope, load, etc.)

and the demands of the driver (power,

acceleration, braking, etc.).

The system never suggests:

-

engaging first gear,

engaging reverse gear,

changing down.

Tyre under-inﬂation detection

System which automatically checks the

This system does not avoid the need

The tyre pressures for your vehicle can

be found on the tyre pressure label.

The tyre pressures must be checked

when the tyres are cold (vehicle

stopped for 1 hour or after driving for

less then 6 miles (10 km) at moderate

speed). Otherwise, add 0.3 bar to the

values indicated on the label.

For more information on Identification

label, refer to the corresponding

section.

pressures of the tyres while driving.

The system continuously monitors the

pressures of the four tyres, as soon as the

vehicle is moving.

to check the tyre pressures regularly

(including the spare wheel) and before

a long journey.

Driving with under-inflated tyres

adversely affects road holding,

extends braking distances and causes

premature tyre wear, particularly under

arduous conditions (vehicle loaded,

high speed, long journey).

Pressure sensors are located in the valve of

each tyre (except the spare wheel).

Driving with under-inflated tyres

increases fuel consumption.

The system triggers an alert if a drop in

pressure is detected in one or more tyres.

The tyre under-inflation detection system is an

aid to driving which does not replace the need

for vigilance on the part of the driver.

Under-inflation alert

Operating fault

The flashing and then fixed

illumination of the under-inflation

warning lamp accompanied by the

illumination of the service warning

lamp indicates a fault with the system.

F

If you have a compressor (e.g. the one in

the temporary puncture repair kit), check

the four tyre pressures when cold.

If it is not possible to check the tyre

pressures at the time, drive carefully at

reduced speed.

or

This alert is also displayed when one or

more wheels is not fitted with a sensor

(e.g. a space-saver or steel spare

wheel).

In the event of a puncture, use the

temporary puncture repair kit or the spare

wheel (depending on equipment).

The alert is given by the fixed

illumination of this warning lamp,

accompanied by an audible signal,

and depending on equipment, the

display of a message.

The alert is maintained until the tyre or

tyres concerned is reinflated, repaired

or replaced.

The spare wheel (space-saver type or

a steel rim) does not have a sensor.

In this case, monitoring of the tyre pressures is

not assured.

In the event of a problem on one of the tyres,

the symbol or the message appears, depending

on equipment, to identify it.

Go to a CITROËN dealer or a qualified

workshop to have the system checked or,

following the repair of a puncture, to have the

original wheel, equipped with a sensor, refitted.

Any tyre repair or replacement on a wheel

fitted with this system must be carried out by a

CITROËN dealer or a qualified workshop.

If after changing a tyre, a wheel is not detected

by your vehicle (e.g. fitting snow tyres),

Reduce speed immediately, avoid sudden

steering movements or harsh brake

applications.

The loss of pressure detected does not

always lead to visible deformation of

the tyre.

CITROËN dealer or a qualified workshop.

Do not rely on just a visual check.
