OBD port Alfa Romeo MiTo 2015 Owner's Manual

Engine coolant overheating
(red)
Turning the key to the MAR position illuminates the warning light, but it
should switch off after a few seconds.
The warning light turns on when the engine is overheated.
The display will show the dedicated message.
If the warning light comes on when driving, proceed as follows:
❒when driving normally: stop the car, switch off the engine and
check that the water level in the reservoir is not below the MIN
mark. If it is, wait for the engine to cool down then slowly
and carefully open the cap, top up with coolant and check that the
level is between the MIN and MAX marks on the reservoir. Also
check visually for leakages. If the warning light comes on again at
the next engine start-up, contact Alfa Romeo Authorised Services.
❒if the vehicle is used under demanding conditions(e.g.
towing trailers uphill or fully loaded): slow down and, if the warning
light stays on, stop the car. Wait for 2 or 3 minutes with the engine
running and slightly accelerated to further favour the coolant
circulation. Then stop the engine. Check the correct fluid level as
described above.
IMPORTANT Over demanding routes, it is advisable to keep the engine
on and slightly accelerated for a few minutes before switching it off.
Doors not closed correctly
(red)
(for versions/markets, where provided)
The warning light (or symbol on the display) lights up when one or
more doors or the tailgate are not closed correctly. An acoustic signal
is activated with the doors open and the car moving.
On some versions the warning light (or symbol on the display) also
lights up when the bonnet is not closed correctly.
EOBD/injection system failure
(amber)
In normal conditions, when the ignition key is turned to MAR-ON the
warning light switches on, but should switch off as soon as the engine
is started.
If the warning light remains on or switches on whilst driving, the
injection system is not working properly; in particular, if the warning
light switches on constantly, this indicates a malfunction in the
supply/ignition system that could cause excessive exhaust emissions, a
possible loss of performance, poor driveability and high fuel
consumption.
A specific message is displayed on certain versions.
Under these conditions, you may continue travelling at moderate speed
without demanding excessive effort from the engine. Prolonged use of
the car with the warning light on may cause damage.
Contact Alfa Romeo Authorized Services as soon as possible.

In “Natural” and “All Weather” operating mode, the active shock
absorbers adjust the car suspension to suit the route type and
the driving stresses, thus considerably improving driving comfort in
particular on rough terrain.
The "Dynamic" operating mode produces a sports driving setting
characterised by more responsive acceleration and greater effort on
the steering wheel to give a sporty feeling. The shock absorber
damping action is also adjusted and divided, to guarantee higher
precision and reactivity of the car, while maintaining a good comfort
level.
The car is more precise when entering bends and quicker in changing
direction.EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace damaged components.
The car also has a diagnostic connector that can be interfaced with
appropriate tools, which makes it possible to read the error codes
stored in the electronic control units together with a series of specific
parameters for engine operation and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.
