Driving -> Starting-switching off the engine for Your Citroen C5 Suv Second Generation (2008-2017)

Driving  
Starting-switching off the engine  
Anti-theft protection  
Ignition switch  
Electronic engine immobiliser  
Ignition on position  
The key contains an electronic chip which has  
a special code. When the ignition is switched  
on, this code must be recognised in order for  
starting to be possible.  
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 moments  
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  
a message in the screen.  
It has 3 positions:  
Do not attach heavy objects to the key  
or remote control: by weighing down on  
the key when in the ignition switch, this  
could cause a fault.  
In addition, a heavy or sharp object  
could interfere with the deployment of  
the knee airbag or be thrown about and  
cause serious injuries in the event of  
deployment of the knee airbag.

Starting the engine  
With the parking brake applied and the gearbox  
in neutral or position N or P:  
F
With a Diesel engine, turn the key to  
position 2, ignition on, to operate the  
engine pre-heating system.  
In temperate conditions, do not leave  
the engine at idle to warm up but move  
off straight away and drive at moderate  
speed.  
F
depress the clutch pedal fully (manual  
gearbox),  
or  
F
F
F
press the brake pedal firmly (automatic  
gearbox),  
insert the key into the ignition switch; the  
system recognises the code,  
unlock the steering column by simultaneously  
turning the steering and the key.  
Wait until this warning lamp goes off in the  
instrument panel then 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.

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 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.  
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.  
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.

Switching off the engine  
Vehicles equipped with a  
turbocharger  
Never stop the engine without having allowed it  
to run for a few seconds at idle, this being the  
time required for the turbocharger to return to a  
normal speed.  
F
Stop the vehicle.  
Energy economy mode  
F
With the engine running at idle, turn the key  
to position 1.  
After switching off the engine (position 1-Stop),

Remove the key from the ignition switch.  
To lock the steering column, turn the  
steering until it locks.  
To facilitate unlocking of the steering  
column, it is recommended that the  
wheels be returned to the straight ahead  
position before switching off the engine.  
For more information on Energy  
economy mode, refer to the  
corresponding section.  
Do not flick the accelerator at the  
moment of switching off the ignition.  
This could cause serious damage to the  
turbocharger(s).  
F
Check that the parking brake is correctly  
applied, particularly on sloping ground.  
Key left in the "Ignition on"  
position  
If the key has been left in the ignition switch  
at position 2 (Ignition on), the ignition will be  
switched off automatically after one hour.  
To switch the ignition back on, turn the  
key to position 1 (Stop), then back to  
position 2 (Ignition on).  
Never switch off the ignition before the  
vehicle is at a complete stop. With the  
engine off, the braking and steering  
assistance systems are also cut off: risk  
of loss of control of the vehicle.  
When you leave the vehicle, keep the  
key with you and lock the vehicle.
