Driving
Gear efficiency indicator
(Depending on engine.)
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may advise to
skip one or more gears.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
This function cannot be deactivated.
On certain BlueHDi Diesel versions with
manual gearbox, the system may suggest
changing into neutral ( N is displayed in the
instrument panel) so that the engine can go into
standby (STOP mode of Stop & Start), in certain
driving conditions.
With an automatic gearbox, the system is
only active in manual operation.
The information appears in the instrument
panel, in the form of an arrow and the
recommended gear.
The system adapts its gear shift
recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never suggests:
– engaging first gear;
– engaging reverse.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system is only active when:
– The vehicle is completely stationary, with your
foot on the brake pedal.
– Certain slope conditions are met.
– The driver’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. Then check that the parking
brake indicator lamp is on fixed in the
instrument panel.
The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts its
operation.
Operation
Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when you
release the brake pedal:
– provided you are in first gear or neutral with a
manual gearbox.
– provided you are in mode D or M with an
automatic gearbox.
Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
These warning lamps come on in
the event of a malfunction,
accompanied by an onscreen message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start function puts the engine
temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
It is set via the Driving / Vehicle touch
screen menu.
A message on the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
