wheel torque FIAT QUBO 2017 1.G Owners Manual

WARNING
If only warning lightlights up in the
instrument panel (with a message in the
multifunction display on some versions), stop
the vehicle immediately and contact the nearest
Fiat Dealership. Fluid leaking from the
hydraulic system will compromise the operation
of the braking system, whether it is of the
conventional type or with ABS.
ESC (Electronic Stability Control)
SYSTEM
(for versions/markets, where provided)
The ESC system improves the directional control and
stability of the vehicle in various driving conditions.
The ESC system corrects the vehicle’s understeer
and oversteer, distributing the brake force on the
appropriate wheels. The torque supplied by the
engine can also be reduced in order to maintain
control of the vehicle.
The ESC system uses the sensors in the vehicle to
determine the trajectory required by the driver
through steering and compares it with the real
trajectory of the vehicle. When the real trajectory
deviates from the desired trajectory, the ESC system
intervenes to counter the car’s understeer or
oversteer.
Oversteer: occurs when the vehicle is turning
more than it should according to the angle of
the steering wheel
Understeer: occurs when the vehicle is turning
less than it should according to the angle of the
steering wheel
The ESC system also includes the following systems:
Hill Holder
ASR
MSR
HBA

SYSTEM INTERVENTION
It is signalled by the blinking of the instrument panel
warning light
, to inform the driver that the car
is in critical stability and grip conditions.
Switching the system on
The ESC system is automatically activated when the
vehicle is started and cannot be deactivated.
Failure indications
In the event of a failure, the ESC system will be
automatically switched off and warning light
will
switch on constantly on the instrument panel along
with a message on the multifunction display (for
versions/markets where provided) (see chapter
"Warning lights and messages"). Contact a Fiat
Dealership as soon as possible.
WARNING
The ESC system can’t overrule the
natural laws of physics, and can’t
increase the grip available according to the
condition of the road.
WARNING
The ESC system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.
WARNING
The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
HILL HOLDER SYSTEM
(for versions/markets, where provided)
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 pedal
pressed and gearbox in neutral or gear other than
reverse;
downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running, brake
pedal pressed and reverse gear engaged.
When setting off, the ESC system control unit
maintains the braking pressure on the wheels until
the torque necessary for starting is reached, or
in any case for a maximum of 2 seconds, allowing
your right foot to be moved easily from the brake
pedal to the accelerator. When two seconds have
elapsed, without starting, the system is automatically
deactivated, gradually releasing the braking pressure.
During this release stage, the typical brake
disengagement noise indicating that the vehicle is
going to move imminently will be heard.

WARNING
The ASR system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.
WARNING
The capability of the ASR system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
MSR SYSTEM (engine drive regulation)
This is an integral part of the ESC system that, in the
event of a sudden gear down shift or an ABS braking,
cuts in and provides torque to the engine thus
preventing excessive driving 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.
When travelling, the ASR system can be switched off
and on again pressing button fig. 91 located among
the controls in the instrument panel.
Switching off is shown by the warning light
on the
instrument panel switching on together with a
message shown in the multifunction display, for
versions/markets where provided.
If the ASR is switched off when driving, it is
automatically switched on again when the vehicle is
started up.
When travelling on snowy roads with snow chains, it
may be helpful to turn the ASR off: in fact, in these
conditions, the driving wheels skidding when moving
off gives you better traction.
