Drive selector (Electric)

The drive selector is a pulse selector with a
regenerative braking function.
The drive selector provides traction control
based on the driving style, the road profile and
the vehicle load.
With regenerative braking activated, it also
manages engine braking when the accelerator
pedal is released.

104
Driving
P.Park
Button for parking the vehicle: the front
wheels are locked (the button lights up to
indicate that it is activated).
R. Reverse
To engage reverse gear, with your foot on the
brake pedal.
N. Neutral
To move the vehicle with the ignition off and
so allow it to free-wheel.
For more information on Free-wheeling, refer
to the corresponding section.
D. Drive (automatic forward gear)
B. Brake (regenerative braking)
Button for changing to Drive/automatic
forward gear
mode with regenerative braking
function (the button lights up to indicate that it
is activated).
Information displayed on
the instrument panel
When the ignition is switched on, the drive
selector status is displayed on the instrument
panel:
P : Park.
R : Reverse.
N : Neutral.
D : Drive (automatic forward gear).
B : Brake (automatic forward gear with
regenerative braking function activated).
Operation
► In mode N, with your foot on the brake pedal,
push without passing the point of resistance: •

Forwards, mode
R is selected.
•

Backwards, mode D

is selected.
Release the selector fully after each push; it
will then return to its initial position.
Special cases
To avoid mode N (quick change from D to R and
back again):
►

In mode
R, push backwards past the point of
resistance, mode D is selected.
►

In mode
D, push forwards past the point of
resistance,
mode R is selected.
►

T
o return to mode N, push without passing
the point of resistance.
Regenerative braking
With the Brake function and when
decelerating
The Brake function emulates engine braking,
slowing the vehicle with no need to depress the
brake pedal. The vehicle slows more quickly
when the driver releases the accelerator pedal.
The energy recovered when the accelerator
pedal is released is then used to partially
recharge the traction battery, thereby increasing
the vehicle's driving range.
The resulting deceleration of the vehicle does not cause the brake lamps to come
on.
► From mode D, press button B to activate/
deactivate the function (the button lights up when
the function is activated).
B is displayed on the instrument panel.
The system status is not saved when the ignition
is switched off.
In some situations (e.g. battery full,
extreme temperatures), the amount of
regenerative braking may be temporarily
limited, resulting in less deceleration.
The driver must remain alert to traffic
conditions and must always be ready to use
the brake pedal.
With the brake pedal
When the brake pedal is depressed, the
intelligent braking system automatically recovers
some of the energy and uses it to recharge the
traction battery.
This energy recovery also reduces use of the
brake pads, thereby limiting their wear.
The driver may experience a different sensation when depressing the brake
pedal compared to a vehicle without
regenerative braking.
Driving modes
The driving modes available depend on the engine and equipment of the vehicle.

105
Driving
6Driving modes are selected using the following
control:




► Press the control to display the modes on the
instrument panel.
When the message disappears, the selected
mode is activated and remains indicated on the
instrument panel (except Normal
mode).
Whenever the ignition is switched on,
Normal
driving mode is selected by default.
Normal
To restore the default settings.
Eco
To reduce energy consumption by reducing the
performance of the heating and air conditioning,
without deactivating them.
Free-wheeling in Eco mode: depending on
version, with the EAT8 gearbox, switching
into "free-wheeling" is encouraged to slow the
vehicle down without using engine braking. You
can save fuel by taking your foot gradually and
fully off the accelerator pedal in anticipation of
slowing down.
To reduce consumption of the traction battery's
electrical energy by limiting engine torque.
Sport
To obtain more dynamic driving with action
on the accelerator and gear changes with an
automatic gearbox.
Hill start assist
This system keeps the 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.
The 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 and the P indicator lamp
in the electric parking brake control are on
fixed.
The hill start assist function cannot be deactivated. However, using the parking
brake to immobilise the vehicle interrupts its
operation.

Highway Driver Assist
Only available on versions with the EAT8
automatic gearbox and drive selector.
This system automatically adjusts the speed
and corrects the trajectory of the vehicle, using
Adaptive cruise control with Stop&Go function in
conjunction with Lane Positioning Assist.
These two functions must be activated and in
operation.
For more information on Adaptive cruise
control and Lane Positioning Assist, refer to
the corresponding sections.
The system assists the driver by acting on the steering, acceleration and braking
within the physical limits
and capacities of the
vehicle. Certain road infrastructure elements
or vehicles in the surroundings may not be
properly seen or may be poorly interpreted by
the camera and radar, resulting in an
unexpected change in direction, a lack of
steering correction and/or inappropriate
management of acceleration or braking.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.

Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
Cruise control - particular
recommendations.
This system automatically maintains the vehicle
speed at a value set by the driver (speed
setting), while respecting a safety distance from
the vehicle in front (target vehicle) previously set
by the driver. The system automatically manages
the acceleration and deceleration of the vehicle.
With the Stop function , the system manages
braking until the vehicle comes to a complete
stop.
With the Stop
& Go function , the system
manages braking until the vehicle comes to a
complete stop and restarts the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
It can be dangerous to drive if the brake
lamps are not in perfect working order.


To do this, the system uses a camera fitted at the
top of the windscreen and a radar fitted in the
front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver activates the direction
indicator to overtake a slower vehicle,
cruise control may temporarily reduce the
distance to the target vehicle to facilitate
overtaking, without exceeding the speed
setting.
