If there is a malfunction in the system, the ABS warning lamp will come on. Under normal conditions, the ABS
warning lamp comes on when the ignition switch is turned to the “ON” position or the operation mode is put in ON
and goes off a few seconds later.
NOTE: On vehicles with the rear differential lock and the active stability & traction control (ASTC), the ASTC and ABS
functions are suspended while the rear differential lock is activated. ASTC indicator lamp, ASTC OFF indicator lamp
and ABS warning lamp are illuminated while these functions are suspended. It does not indicate a problem. When
the rear differential lock is disengaged, these lamps go out and function again. Refer to “ASTC indicator lamp, ASTC
OFF indicator lamp”.
If only the ABS warning lamp illuminates:
Avoid hard braking and high-speed driving. Stop the vehicle in a safe place.
Restart the engine and check to see whether the lamp goes out after a few minutes driving; if it
then remains off during driving, there is no problem.
However, if the warning lamp do not disappear, or if they come on again when the vehicle is driven, we recommend
you to have the vehicle checked as soon as possible.
If the ABS warning lamp and brake warning lamp illuminate at the same time:
The ABS and brake force distribution function may not work, so hard braking could make the
vehicle unstable.
Avoid hard braking and high-speed driving.
Stop the vehicle in a safe place and we recommend you to have the vehicle checked.

WARNING
102)In the following situations, brake
performance may be compromised or the
vehicle may become unstable if brakes are
applied suddenly; consequently, avoid
driving at high speeds or applying the
brakes suddenly. Furthermore, immediately
the vehicle should be brought to a stop in a
safe location and we recommend you to
have it checked. 1 – The brake warning
lamp does not illuminate when the parking
brake is applied or does not turn off when
the parking brake is released.2–The
brake warning lamp and the ABS warning
lamp illuminate at the same time. For
details, refer to “ABS warning lamp”. 3 –
The brake warning lamp remains
illuminated while driving.
103)The vehicle should be brought to a
halt in the following manner when brake
performance has deteriorated. 1 – Depress
the brake pedal harder than usual. Even if
the brake pedal moves down to the very
end of its possible stroke, keep it pressed
down hard. 2 – Should the brakes fail, use
engine braking to reduce your speed and
carefully pull the parking brake lever.
Depress the brake pedal to operate the
stop lamp to alert the vehicles behind you.
IMPORTANT
42)This warning lightwill flash after
starting or during prolonged cranking to
indicate a fault with the glow plug heating
system. If the engine starts, the vehicle can
be used as normal, but a Fiat Dealership
must be contacted as soon as possible.
43)If the diesel preheat indicator lamp
comes on after the engine is started, the
engine speed may not rise above the idling
speed because of fuel freezing. In this case,
keep the engine idling for about
10 minutes, then turn off the ignition switch
or put in OFF the operation mode, and
immediately turn it on or put in ON again to
confirm that the diesel preheat indicator
lamp is off.
44)When the ignition switch is turned to
the “ON” position or the operation mode is
put in ON, the warning lamp does not
come on or it remains on and does not go
off . The warning lamp comes on while
driving.
45)When this indicator lamp blinks, active
stability control function or active traction
control function is operating, which means
that the road is slippery or that your
vehicle’s wheels are beginning to slip. If this
happens, drive slower with less accelerator
input.46)If an abnormal condition occurs in the
system while driving, the
indicator lamp
will illuminate. In these cases, follow these
procedures:1–Ifthetemperature in the
braking system continues to increase due
to continuous brake control on a slippery
road surface, the
indicator lamp will
blink, and operation of the active traction
control function will be suspended to
protect the brake system (the engine
control of the traction control function and
normal brake operation will not be
affected.) Park your vehicle in a safe place.
When the temperature in the braking
system has come down, the indicator lamp
will go off and the active stability control
function and active traction control function
will start operating again.2–Ifthe
indicator lamp does not go out even
through the above procedure is followed,
there could be a problem in the system.
Stop the engine and start the engine again
and check whether the
indicator lamp
goes out. If the indicator lamp goes out,
there is no abnormal condition.3–Ifthe
indicator lamp illuminates even after
your vehicle is driven a short distance after
re-starting the engine, we recommend you
to have your vehicle checked as soon as
possible.

is running, avoid driving at high speeds and
have the system inspected by a Fiat
Dealership as soon as possible. Accelerator
pedal and brake pedal response may be
negatively influenced under these
conditions.
51)If it illuminates while the engine is
running, there is a problem in the charging
system. Immediately park your vehicle in a
safe place and we recommend you to have
it checked.
52)If this lamp illuminates when the engine
oil level is not low, have it inspected.
53)This warning lamp does not indicate
the amount of oil in the crankcase. This
must be determined by checking the oil
level on the dipstick, while the engine is
switched off.54)If you continue driving with low engine
oil level or with this warning lamp
illuminated, engine seizure may occur.
55)Before moving your vehicle, check that
the warning lamp is OFF.
56)If any of the following conditions occur,
there may be a problem with the SRS
airbags and/or seat belt pre-tensioners,
and they may not function properly in a
collision or may suddenly activate without a
collision: 1 – Even when the ignition switch
or the operation mode is in ON, the SRS
warning lamp does not come on or it
remains on. 2 – The SRS warning lamp
comes on while driving.
57)The SRS airbags and seat belt
pre-tensioners are designed to help reduce
the risk of serious injury or death in certain
collisions. If either of the above conditions
occurs, immediately have your vehicle
checked by a Fiat Dealership.

gearshift lever into the “R” position.
3. Release the brake pedal and the hill
start assist will maintain the braking
force applied while stopping for
approximately 2 seconds.
4. Depress the accelerator pedal and
the hill start assist gradually will
decrease the braking force as the
vehicle starts moving.NOTE The hill start assist is activated
when all of the following conditions are
met.
The engine is running (the hill start
assist will not be activated while the
engine is starting or immediately after
the engine is started).
On vehicles equipped with M/T, the
gearshift lever is in the following
position: When starting an uphill slope
forwards > The gearshift lever is in any
position other than “R” (the hill start
assist will operate, even if the gearshift
lever is in the “N” position). When
starting an uphill slope backwards >
The gearshift lever is in the “R” position
(the hill start assist will not operate
