gearbox Citroen DS5 HYBRID 2016 1.G Service Manual

7Hybrid4 system

Compared to a manual gearbox, the ETG6
electronic gearbox (6)
provides, in automatic
mode, significant savings in fuel consumption,
through the electronic management of gear
changes.
The mode selector (8)
allows selection of the
four operating modes offered by the Hybrid4
system:


- AUTO
mode, which optimises fuel
consumption by automatically managing
the alternate or simultaneous use of the
two motors,

- ZEV
(Zero Emissions Vehicle) mode, which
provides 100% electric drive, when the
driving conditions and the state of charge
of the battery permit,

- SPORT
mode, which provides more
dynamic driving with additional
performance,

- 4WD
(4 Wheel Drive) mode, which
improves traction at low speed when grip is
poor (snow, mud, sand...).

Moving off


For more information on the
electric parking brake, refer to the
corresponding section in the handbook
for the vehicle.

You can change the operating mode of the
Hybrid4 system at any time using its mode
selector.
Driving in ZEV
mode requires that particular
conditions be met.

When your vehicle vehicle moves off
in electric mode, it makes no noise. Be
very careful of pedestrians, cyclists...
as, because of this, they will not hear
you coming.

Head-up display

The colour of the speedometer varies
according to the drive train used:


- white display: Diesel engine
running,

- blue display: Diesel engine
stopped.

Using automatic mode with the
electronic gearbox optimises gear
changes and so gives more economical
driving.


)
If automatic operation of the electric
parking brake has been deactivated, pull
then release the control lever to release the
parking brake manually.

)
Progressively release the brake pedal.

)
With the parking brake released, the
vehicle then moves off.
If the parking brake is still applied and is in
automatic mode, accelerate progressively.

)
Move the gear selector to
position A
(automatic mode) or M
(manual
mode) or R
(reverse).

21Hybrid4 system

This mode will be even more effective if
the vehicle is fitted with suitable tyres,
such as winter tyres.



SPORT mode
(Diesel and
electric)
4WD mode
(4 - wheel drive)

This mode allows more dynamic driving by
providing additional performance
.
By using the capacity of the electric motor
to supplement the power of the HDi Diesel
engine, the vehicle's full power is used for
acceleration and pick-up.
This mode manages the response of the
accelerator, the electronic gearbox and the use
of the electric motor.
In SPORT
mode:


- the electric motor as an addition is
available up to 75 mph (120 km/h).


This "4-wheel drive" mode provides additional
traction
at low speed by driving all four wheels
of the vehicle simultaneously: the HDi Diesel
engine (front wheel drive) and the electric
motor (rear wheel drive) operate simultaneously
and permanently.
Their coupling is managed electronically to
optimise traction when grip is poor.
In 4WD
mode:


- the HDi Diesel engine operates
continuously; if necessary, it supplies
energy for the electric motor,

- the additional traction from the electric
motor is available up to 75 mph (120 km/h).

This mode should be used on snow
covered roads or difficult ground (mud,
sand, ...), as well as for crossing a ford,
at moderate speed.
In this mode, in severe conditions
and if the circumstances allow, it is
recommended that you accelerate
strongly to facilitate moving off and
making progress and so reduce the risk
of getting stuck.

This mode is available whatever:


- the state of charge of the high
voltage battery,

- the altitude.

Driving recommendations


Obser ve the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
On a long journey, a break every two hours is
strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.



Driving on flooded roads


We strongly advise against driving on flooded
roads, as this could cause serious damage
to the internal combustion engine or electric
motor, the electronic gearbox, or the electrical
systems of your vehicle. If you are obliged to drive through water:


- check that the depth of water does not
exceed 15 cm, taking account of waves
that might be generated by other users,

- place the mode selector in the 4WD

position,

- drive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10 km/h),

- do not stop and do not switch off the
engine.
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.



Important!


Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Do not park or run the engine when
stationary in areas where inflammable
substances and materials (dry grass,
dead leaves...) might come into
contact with the hot exhaust system
or certain components of the Hybrid4
system which can reach very high
temperatures - Risk of fire!

Never leave a vehicle unsuper vised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the electronic gearbox into
position N
.
