(activated by default),
-

M
anual application/release
The parking brake can be applied/released
manually by pulling control lever .
If this warning lamp comes on in

Malfunction
When the ignition is on, a message appears
in the instrument panel screen to indicate a
gearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel a
substantial jolt when changing from P to R and
from N to R. This will not cause any damage to
the gearbox.
Do not exceed around 60 mph (100 km/h), local
speed restrictions permitting.
Have it checked by a network dealer or a
qualified workshop.There is a risk of damage to the gearbox:
-

i
f you press the accelerator and brake
pedals at the same time,
-

i
f you force the selector from position P
to another position when the battery is
flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear selector at N and apply the
parking brake, unless it is programmed
in automatic mode.
Gear efficiency indicator
(Depending on engine.) System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. The system adapts its gear change
recommendation according to the
driving conditions (slope, load,...) and
the demands of the driver (power,
acceleration, braking,...).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
The information appears in the instrument
panel in the form of an arrow. With a manual gearbox, the arrow may be
accompanied by the gear recommended.
