Driving

Anti-theft protection Starting / Switching off the engine with the key

Electronic engine immobiliser

Ignition switch

The keys contain an electronic chip which has

a special code. When the ignition is switched

on, this code must be recognised for engine

starting to be authorised.

Ignition on position

It allows the use of the vehicle's electric

equipment or portable devices to be charged.

Once the state of charge of the battery drops

to the reserve level, the system switches to

energy economy mode: the power supply is

cut off automatically to preserve the remaining

battery charge.

This electronic engine immobiliser locks the

engine management system a few minutes

after the ignition is switched off and prevents

starting of the engine by anyone who does not

have the key.

In the event of a fault, you are

informed by illumination of this

warning lamp, an audible signal

and/or the display of a message,

depending on version.

It has 3 positions:

Avoid attaching heavy objects to the

key or the remote control, which would

weigh down on its blade in the ignition

switch and could cause a malfunction.

It could adversely affect the deployment

of the front airbag.

-

position 1 (Stop): insert and removing

the key,

-

position 2 (Ignition on): steering column

unlocked, ignition on, Diesel preheating,

engine running,

In this case, your vehicle will not start; contact

a CITROËN dealer as soon as possible.

-

position 3 (Starting).

Keep safely, away from your vehicle,

the label attached to the keys given to

you on acquisition of the vehicle.

Switching off the engine leads to a loss

of braking assistance.

F

With a Diesel engine, turn the key to

position 2, ignition on, to operate the

or

F

release the key.

insert the key into the ignition switch; the

system recognises the code,

unlock the steering column by

simultaneously turning the steering and

the key.

Never leave the engine running in

an enclosed area without adequate

ventilation: internal combustion

engines emit toxic exhaust gases,

such as carbon monoxide. Danger of

intoxication and death!

In certain cases, you may have to apply

more force to the steering (wheels on

full lock, for example).

In wintry conditions, the warning lamp

can stay on for a longer period. When

the engine is hot, the warning lamp

does not come on.

In very severe wintry conditions

(temperatures below -23°C), to ensure

the correct operation and durability of

the mechanical components of your

vehicle, engine and gearbox, it is

necessary to leave the engine running

for 4 minutes before moving off.

F

With a petrol engine, operate the starter

motor by turning the key to position 3

without pressing the accelerator pedal,

until the engine starts. Once the engine is

running, release the key.

If the engine does not start straight

away, switch off the ignition. Wait a

few moments before operating the

starter motor again. If the engine does

not start after several attempts, do not

keep trying: you risk damaging the

starter motor or the engine. Contact

a CITROËN dealer or a qualified

workshop.
