Automatic restarting of the Diesel engine or ZEV mode NOT available
The internal combustion engine may
restart or ZEV mode may not be avail-
able in the various conditions presented
below.
The internal combustion engine can
be switched off automatically as soon
as these conditions are lifted.
When the conditions described below
cause the vehicle to come out of ZEV
mode and the Diesel engine to restart,
the vehicle automatically changes to
AUTO mode.
Action by the driver
- Moving the gear selector to posi-
tion M
.
- Action on steering mounted control
paddles to change gear.
- Sustained and sharp acceleration.
- Use of demisting.
- Use of air conditioning.
Maintaining the performance of the
system
- When the vehicle exceeds 18 mph
(30 km/h) after moving off (if the in-
ternal combustion engine has not
already started since the vehicle
was last started).
- If the high voltage battery is not
suffi ciently charged. A minimum of
4 bars in ZEV mode so as to en-
sure operation over a certain dis-
tance (in AUTO, electric operation
is accessible for a shorter period
with a lower level of charge).
- When the fuel level enters the
reserve zone (where rate of con-
sumption of this reserve is high,
ZEV inhibition may continue for
some time after refuelling).
- During regeneration of the par-
ticle emissions fi lter, which occurs
automatically for 5 to 10 minutes,
approximately every 300 miles
(500 kms) (or less in extended ur-
ban running).
Diffi cult weather conditions and
circumstances
- If certain conditions or engine
temperature requirements make
it necessary (such as an engine
temperature that is too low for the
ambient conditions).
- When the battery is close to maxi-
mum charge (for example: when
going down a long hill), because
engine recovery being no longer
possible, the internal combustion
engine restarts automatically just
to provide engine braking.
- If the vehicle encounters a steep
slope (car park ramp, ...).
- If the vehicle has been parked in
the sun for a prolonged period.
- When driving in mountainous con-
ditions (altitude).
Your vehicle is fi tted with the most
effective emissions control systems,
in particular the Particle Emissions
Filter (PEF).
At regular intervals your Diesel en-
gine will produce energy for the self-
cleaning of this fi lter.
During this PEF regeneration phase,
electric running is purposely made
unavailable.
