GEAR SHIFT INDICATOR *

System which reduces fuel consumption
by advising the driver to change up on ve-
hicles fi tted with a manual gearbox.

*
According to engine.


Operation

The system intervenes only when driving
economically.
Depending on the driving situation and
your vehicle's equipment, the system may
advise you to skip one or more gears. You
can follow this instruction without engag-
ing the intermediate gears.
The gear engagement recommendations
must not be considered compulsory. In
fact, the confi guration of the road, the
amount of traffi c and safety remain de-
termining factors when choosing the best
gear. Therefore, the driver remains re-
sponsible for deciding whether or not to
follow the advice given by the system.
This function cannot be deactivated.
- You press the accelerator pedal
moderately.
Example:


- You are in third gear.

- The system may suggest that you
engage a higher gear, if appropriate.
The information appears in the instru-
ment panel screen in the form of an
arrow accompanied by the suggested
gear.

In the case of driving which
makes particular demands on
the performance of the engine
(fi rm pressure on the accelerator
pedal, for example, when over-
taking...), the system will not rec-
ommend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

The gearbox then operates in auto-
adaptive mode, without any intervention on the part of the driver. It continuously
selects the most suitable gear accord-
ing to the style of driving, the profi le of
the road and the load in the vehicle.
For maximum acceleration without
touching the lever, press the accelera-
tor pedal down fully (kick down). The
gearbox changes down automatically
or maintains the gear selected until the
maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide effi cient engine
braking.
If you release the accelerator sharply,
the gearbox will not change to a higher
gear for safety reasons.

Never select position N
while the
vehicle is moving.

disappears and the gears
engaged appear in succes-
sion in the instrument panel.
If the engine speed is too low
or too high, the gear selected
fl ashes for a few seconds, then the ac-
tual gear engaged is displayed.
It is possible to change from position D

(automatic) to position M
(manual) at
any time.
When the vehicle is stationary or moving
very slowly, the gearbox selects gear M1

automatically.

Invalid value during manual
operation
This symbol is displayed if a
gear is not engaged correctly
(selector between two posi-
tions).



Stopping the vehicle

Before switching off the engine, you
can engage position P
or N
to place the
gearbox in neutral.
In both cases, apply the parking brake
to immobilise the vehicle, unless it is
programmed to automatic mode.

If the lever is not in position P
,
when the driver's door is opened
or approximately 45 seconds af-
ter the ignition is switched off,
there is an audible signal and a
message appears.


)
Return the lever to position P
;
the audible signal stops and
the message disappears.


You risk damaging the gearbox:


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

- if you force the lever from po-
sition P
to another position
when the battery is fl at. When the ignition is on, the
lighting of this warning lamp,
accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to
back-up mode and is locked in 3rd gear.
You may feel a substantial knock when
changing from P
to R
and from N
to R
.
This will not cause any damage to the
gearbox.
Do not exceed 60 mph (100 km/h), local
speed restrictions permitting.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
This warning lamp may also come on if
a door is opened.
Operating fault
To reduce fuel consumption
when stationary for long periods
with the engine running (traffi c
jam...), position the gear lever at
N
and apply the parking brake,
unless it is programmed in auto-
matic mode.

HILL START ASSIST
System which keeps your vehicle im-
mobilised temporarily (approximately
2 seconds) when starting on a gradi-
ent, the time it takes to move your foot
from the brake pedal to the accelerator
pedal.
This function is only active when:


- the vehicle is completely stationary,
with your foot on the brake pedal,

- when certain conditions of gradient
are met,

- with the driver’s door closed.
The hill start assist function cannot be
deactivated.

On an ascending slope, with the ve-
hicle stationary, the vehicle is held
for a brief moment when you release
the brake pedal:



- provided you are in fi rst gear or neu-
tral with a manual gearbox,

- provided you are in position A
or M

with the electronic gearbox system,

- provided you are in position D
or M

with an automatic gearbox.


Operation


Do not leave the vehicle while it
is being held in the hill start assist
phase.
If you need to leave the vehicle
while the engine is running, apply
the parking brake manually then
ensure that the parking brake
warning lamp is on (not fl ashing)
in the instrument panel.

On a descending slope, with the vehicle
stationary and reverse gear engaged,
the vehicle is held for a brief moment
when you release the brake pedal.

Operating fault

If a malfunction of the system occurs,
these warning lamps come on. Contact
a CITROËN dealer or a qualifi ed work-
shop to have the system checked.
