2010 FIAT QUBO wheel size

HILL HOLDER SYSTEM
(for versions/markets, where provided)
It's integral to the ESP system. It automatically
activates with 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.
At pickup the ESP system control unit will keep
brake force on wheels until reaching the torque
suitable for starting, or in any case for max. 2
seconds in order to pass easily from the brake pedal
to the accelerator pedal.
When 2 seconds have elapsed, without any
departure having taken place, 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.
Failure indications
IMPORTANT The Hill Holder system is not a parking
brake; therefore, never leave the vehicle without
having engaged the handbrake, turned the engine off
and engaged the first gear.WARNING
For the correct operation of the ESP and
A
SR systems, the tyres must be the
same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size recommended.
ASR SYSTEM (Anti-Slip Regulation)
(for versions/markets, where provided)
This is a traction control system that cuts in
automatically every time one or both drive wheels
slip.
Depending on how slippery the road is, two different
control systems are activated:
❒if slipping involves both driving wheels, the ASR
function 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 especially useful in
the following conditions:
❒slipping of the inner wheel round bends due to
dynamic variations in the load of excessive
acceleration;
❒excessive power transmitted to the wheels, also in
relation to road surface conditions;

❒acceleration on slippery, snowy or icy road
surfaces;
❒in the case of loss of grip on a wet surface
(aquaplaning).
WARNING
For the correct operation of the ESP and
A
SR systems, the tyres must be the
same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size recommended.
MSR SYSTEM (engine drive regulation)
This is an integral part of the ASR 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.
When travelling, the ASR can be switched off and on
again pressing button A fig. 90located among the
controls in the dashboard.The switching off is shown by the LED in the actual
switch coming 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.
WARNING
Do not take unnecessary risks, even if
y
our vehicle is fitted with this system.
Your driving style must always be suited to the
road conditions, visibility and traffic .
The driver is always responsible for road safety.

For the correct operation of the ASR system, the
tyres must absolutely be the same make and type on
all wheels, in perfect condition and, above all, of
the type, make and size specified.
FAILURE INDICATIONS
In the event of a failure, the ASR system will be
automatically switched off and warning light
will
appear permanently on the instrument panel along
with a message on the multifunction display (for
versions/markets where provided) (see “Warning
lights and messages”). In this case, contact a Fiat
Dealership as soon as possible.
TRACTION PLUS SYSTEM
(for versions/markets, where provided)
Traction Plus is a help with driving and setting off in
poor grip conditions (snow, ice, mud, etc.) which
allows the drive force to be evenly distributed over
the same axle when both wheels are slipping.
In effect, 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 more grip on the ground.
This function can be turned on manually by pressing
the T+ button fig. 91 on the dashboard and works
below a level of 30 km/h. Over this speed, it is
automatically deactivated (the LED on the button is
still on) and it is reactivated again when the speed
is below 30 km/h.

WARNING
This procedure must be performed by
e
xperts because incorrect actions may
cause considerable electrical discharge.
Furthermore, battery fluid is poisonous and
corrosive: avoid contact with skin and eyes.
Keep naked flames and lit cigarettes away from
the battery. Do not create sparks.
BUMP STARTING
Never bump start the engine by pushing, towing or
driving downhill. This could cause fuel to flow into
the catalytic converter and damage it beyond repair.
IMPORTANT Remember that the brake booster
and the power steering system are not active until
the engine is started, so you will need to apply much
more force to the brake pedal or steering wheel.
CHANGING A TYRE
The vehicle is originally equipped with the Fix&Go
automatic quick tyre repair kit (see instructions
in the next chapter). As an alternative, the vehicle
may have a normal-sized spare wheel.
Changing the wheel and correct use of the jack and
spare wheel require some precautions, which are
listed below.
WARNING
The spare wheel (for versions/markets,
w
here provided) is specific for your
vehicle.Therefore, it must not be used on other
models. Do not use spare wheels of other
models on your vehicle.The spare wheel must
be used only in an emergency. Use of the spare
wheel must kept to the minimum necessary.
