Citroen C3: Starting / Switching off the engine with Keyless
Entry and Starting / Key not detected. Emergency switch-off
Key not detected
Back-up starting
A back-up reader is fitted to the steering column
so that the engine can be started if the system
does not detect the key in the recognition zone,
or if the battery in the electronic key is flat.

- Place and hold the remote control against the
reader.
- With a manual gearbox, place the gear lever
in neutral then fully depress the clutch pedal.
- With an automatic gearbox, select mode P,
then fully depress the brake pedal.
- Press the “START/STOP” button.
The engine starts.
Back-up switch-off

If the electronic key is not detected or is no
longer in the recognition zone, a message
appears in the instrument panel when closing a
door or trying to switch off the engine.
- To confirm the instruction to switch off the
engine, press the "START/STOP" button for
approximately 5 seconds.
In the event of a fault with the electronic key,
contact a CITROËN dealer or a qualified
workshop.
Emergency switch-off
In the event of an emergency only, the engine
can be switched off without conditions (even
when driving).
- Press the "START/STOP" button for about
5 seconds.
In this case, the steering column locks as soon
as the vehicle stops.
With the electronic key in the passenger
compartment, pressing the “START/STOP”
button, without pressing any of the pedals,
allows the ignition to be switched on without
starting the engine...
Release
Pull the parking brake lever up slightly, press
the release button, then lower the lever fully.
When driving the vehicle, if
this warning
lamp and the STOP warning lamp come
on, accompanied by an audible signal and the
display of a message, this means that the
parking brake is still applied or has not been fully
released...

certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.

use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes...
