2015 FIAT DOBLO COMBI wheel torque

ESC (Electronic
Stability Control)
SYSTEM
(for versions/markets, where
provided)
IN BRIEF
This is an electronic system that
controls vehicle stability in the
event of tyre grip loss, helping to
maintain directional control.
The ESC system is therefore
particularly useful when grip
conditions of road surfaces
change.
The MSR system (adjustment of
the engine braking torque during
gear changes) and the HBA
system (automatic increase in the
braking pressure during
emergency braking) are present
with ESC, ASR and Hill Holder
systems (for versions/markets
where provided).SYSTEM
INTERVENTION
This is signalled by the flashing of
the
warning light in the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
SYSTEM ACTIVATION
The ESC system is automatically
activated when the vehicle is
started.
FAULT INDICATIONS
In the event of a fault, the ESC will
be automatically switched off and
the
warning light will come on
permanently on the instrument panel
along with a message on the
multifunction display (for versions/
markets where provided) (see
"Warning lights and messages"
section). The LED on the ASR OFF
button will also light up. Contact
a Fiat Dealership as soon as
possible.

HILL HOLDER SYSTEM
This system is an integral part of the
ESC system and facilitates starting
on slopes. It is automatically
activated in the following conditions:
❒uphill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
gearbox in neutral or gear (other than
reverse) engaged;
❒downhill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
reverse gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure at the wheels until the
torque necessary for starting is
reached, or in any case for a
maximum of 1.75 seconds, allowing
your right foot to be moved easily
from the brake pedal to the
accelerator.
If the vehicle has not departed after
1.75 seconds, the system will
deactivate automatically by gradually
releasing the brake force.

SAFETY

During this release stage, the typical
brake disengagement noise
indicating that the vehicle is going to
move imminently will be heard.
Fault indications
Any system fault is indicated by the
turning on of the
warning light on
the instrument panel with digital
display and the
warning light on
the instrument panel with
multifunction display (for versions/
markets where provided) (see
section “Warning lights and
messages”).
IMPORTANT The Hill Holder system
is not a parking brake, therefore
do not leave the vehicle without
activating the handbrake, switching
off the engine and engaging first
gear.
59)
ASR SYSTEM (Antislip
Regulator)
This is a traction control system that
cuts in automatically every time
one or both drive wheels slip.Depending on the slipping
conditions, two different control
systems are activated:
❒if the slipping involves both drive
wheels, the ASR intervenes reducing
the power transmitted by the engine;
❒if the slipping only involves one of the
drive wheels, it intervenes
automatically braking the wheel that
is slipping.
The action of the ASR system is
particularly helpful in the following
circumstances:
❒slipping of the inner wheel on bends
due to dynamic variations in the load
or excessive acceleration;
❒excessive power transmitted to the
wheels, also in relation to road
surface conditions;
❒acceleration on slippery, snowy or icy
road surfaces;
❒loss of grip on wet road surfaces
(aquaplaning).
MSR system (engine
drive regulation)
This is a system that, in the event of
a sudden gear down shift, cuts in
and provides torque to the engine
thus preventing excessive drive
wheel drive which, especially in poor
grip conditions, can lead to a loss
of stability.
Engagement/
disengagement of the
ASR system
The ASR system switches on
automatically each time the engine
is started.
Whilst driving, the ASR can be
switched off and subsequently
switched on again by pressing the
fig. 118 button on the dashboard.
Switching off is shown by the
warning light on the instrument
panel switching on and a dedicated
message shown in the multifunction
display, where provided.
If the ASR is switched off when
driving, it is automatically switched
on again when the vehicle is started
up.
113

TRACTION PLUS
SYSTEM
(for versions/markets, where
provided)
Traction Plus is a driving aid, useful
for setting off in poor grip conditions
(snow, ice, mud, etc.) which allows
the drive force to be distributed in
the best way over the front axle
when one wheel is slipping.
Traction Plus acts by braking the
wheels with poor grip (or those
slipping more than the others),
thereby transferring the drive force
to those which have greater grip on
the ground.
This function can be activated
manually by pressing the A fig. 147
button on the control panel and
operates under 50 km/h. When this
speed is exceeded, it is
automatically deactivated and it is
reactivated again when the speed
falls below 50 km/h.Traction Plus
operation
The system is deactivated when
starting. To activate the Traction Plus
system press the A fig. 147 button.
The activation of the Traction Plus
system involves the following
functions being switched on:
❒inhibition of the ASR function, in
order to fully exploit the engine
torque;
❒the differential locking effect on the
front axle, through the braking
system, to improve traction
on irregular grounds.
If the Traction Plus system is faulty,
the
warning light on the
instrument panel switches on
constantly.
PARKING SENSORS
These are located in the rear
bumper fig. 148 and their function is
to inform the driver, through an
intermittent beeping noise, about
the presence of obstacles behind
the vehicle.
ACTIVATION
The sensors are automatically
activated when reverse is engaged.
As the obstacle behind the vehicle
gets closer to the bumper, the
frequency of the acoustic signal
increases.
