Remember that the deterioration of the engine oil is
accelerated by:
GETTING TO KNOW
YOUR CAR
❒ mainly town use of the car which makes the DPF
regeneration process more frequent;
❒ use of the car for short drives, in which the engine
does not have time to reach its regular operating
SAFETY
temperature;
❒ repeated interruption of the regeneration process,
signalled by the DPF warning light coming on.
STARTING AND
DRIVING
If the warning light switches on, the
WARNING LIGHTS
deteriorated engine oil must be changed
AND MESSAGES
as soon as possible, and never more than 500
km from the first time that the warning light
switches on. Failure to observe the above may
result in severe damage to the engine and
IN AN EMERGENCY
invalidate the warranty.The activation of this
warning light is not related to the amount of oil
in the engine.Therefore, never top up with oil
when the warning light starts flashing.

WARNING
HOT ENGINE COOLANT
(red)
The warning light switches on (on some versions
together with a message and a symbol on the display)
when the engine is overheated.
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
any fluid leaks. If, when restarting, the warning
light comes on again, contact a Fiat Dealership;
❒ if the vehicle is used under demanding
conditions (e.g. towing trailers uphill or fully
loaded): slow down and, if the 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 coolant level as described
above. Should the level of fluid be too low, top up
(for the quantity and type of fluid to use, see
the description in the "Refuelling" paragraph in the
"Technical specifications" chapter).
IMPORTANT Over demanding routes, it is advisable
to keep the engine on and slightly accelerated for
a few minutes before switching it off.
