ZEV mode * (all electric)
Zero emissions vehicle operation is as-
sured 100 % by electric drive.
This mode forces silent running
at
moderate speeds.
* ZEV: Zero Emissions Vehicle. In ZEV mode:
- The accelerator control is progres-
sive.
- Range and acceleration capacity
are limited. The maximum speed
possible is around 36 mph (60 km/h).
- Under high load or a priority require-
ment causing the start of the Diesel
engine, the system changes auto-
matically to AUTO mode.
It can be activated when
the required conditions are
met, particularly if the state
of charge of high voltage
battery is suffi cient (from 4 bars).
If the conditions do not allow
this mode, a message that
the "electric mode is not cur-
rently available" appears in
the screen. The ZEV warning
lamp fl ashes for a few seconds then
goes off and the selector comes on in
AUTO.
Auto mode
It automatically manages the operation
of the Diesel engine and the electric
motor, according to inherent vehicle pa-
rameters, traffi c conditions and driving
style so as to optimise the vehicle's
fuel consumption
.
In particular, this mode activates "zero
emissions" electric running
when the
conditions allow.
In auto mode, the electric motor
:
- can drive the vehicle on its own up
to around 36 mph (60 km/h) in "zero
emissions" electric running, depend-
ing on the state of charge of the bat-
tery, if the conditions specifi c to the
vehicle are met and if acceleration is
moderate,
- supplements the Diesel engine
when moving off and changing gear,
during acceleration and when trac-
tion from the front wheels is inade-
quate (it automatically adds
4 wheel
drive
),
- is no longer active above 70 mph
(120 km/h).
This standard
mode to use in
preference
is activated auto-
matically
on starting the hy-
brid system.

tomatic restarting of the Diesel
engine or ZEV mode not avail-
able", refer to the correspond-

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 present-
ed 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 particle
emissions fi lter, which occurs auto-
matically for 5 to 10 minutes, approxi-
mately every 300 miles (500 kms)
(or less in extended urban 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 ef-
fective emissions control systems, in
particular the Particle Emissions Fil-
ter (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.

CHECKS
Before doing anything under
the bonnet, switch off the igni-
tion ( Ready
lamp off) to avoid
any risk of injury resulting from auto-
matic operation of the engine.
Unless otherwise indicated, check these
components in accordance with the
servicing booklet and according to your
engine.
Otherwise, have them checked by a
PEUGEOT dealer or a qualifi ed workshop.
The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "12 V battery" section for
details of the precautions to be taken
before disconnecting the battery and
following its reconnection.
12 V battery
Air filter and passenger compartment filter
Refer to the servicing booklet
for details of the replacement
intervals for these compo-
nents.
Depending on the environment
(e.g. dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
.
A clogged passenger compartment fi lter
may have an adverse effect on the per-
formance of the air conditioning system
and generate undesirable odours.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the servicing booklet
for details of the replacement
interval for this component.
Particle emission filter (Diesel)
As soon as the traffi c condi-
tions permit, regenerate the
fi lter by driving at a speed of
at least 40 mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this in-
dicates a low additive level.
The 100% electric mode is not avail-
able during regeneration of the particle
emissions fi lter. The start of saturation of the
particle fi lter is indicated by
the temporary illumination
of this warning lamp accom-
panied by a message in the
multi-function screen.
On a new vehicle, the fi rst particle
fi lter regeneration operations may be
accompanied by a "burning" smell,
which is perfectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
