Driving
Starting a diesel engine after having run
out of fuel
If the fuel t
ank has been completely run dry, it
may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first.
WARNING
Do not keep the engine running in confined
spaces, as ther
e is a danger of poisoning.
●
The exhaust gases contain carbon mon-
oxide, an odourless and colourless poison-
ous gas that can cause loss of conscious-
ness and death.
WARNING
Do not get out of the vehicle with the en-
gine running, especially if a gear is engag-
ed. The v
ehicle could then suddenly move
or something strange could happen that
would cause damage, fire or serious injury.
WARNING
Never use cold start sprays, they could ex-
pl
ode or cause the engine to run at high
revs. Doing this risks injury.
CAUTION
●
The st
arter motor or the engine may be
damaged if you try to start the engine while
driving or if you restart it immediately after
s
witching it off.
●
When the engine is cold, you should
avoid high engine speeds, driving at full
throttle and over-loading the engine. Risk
of engine damage.
For the sake of the environment
Do not warm-up the engine by running the
engine with the v
ehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions.
Note
●
El
ectrical components with a high power
consumption are switched off temporarily
when the engine starts.
●
When starting with a cold engine, noise
levels may briefly increase. This is quite
normal, and no cause for concern.
●
When the outside temperature is below
+5 °C (+41 °F), if the engine is diesel, some
smoke may appear under the vehicle when
the fuel-operated auxiliary heater is on.
●
In vehicles with a natural gas engine
(CNG), by default, the engine starts with
gas, with the exception of the following ca-
ses:
–
Coolant temperature below -15°C.
–
After refuelling CNG.

WARNING
Never switch off the engine while the vehi-
cl
e is moving. This could cause loss of con-
trol of the vehicle, accidents and serious in-
jury.
●
The airbags and belt tensioners do not
work when the ignition is switched off.
●
The brake servo does not work with the
engine off. Therefore, you need to press the
break pedal harder to brake the vehicle.
