Gear Shift Indicator (GSI) — If Equipped
The Gear Shift Indicator (GSI) system is en-
abled on vehicles when automatic transmis-
sion is in manual shift mode. The GSI pro-
vides the driver with a visual indication when
the recommended gear shift point has been
reached. This indication notifies the driver
that changing gear will allow a reduction in
fuel consumption. When the up shift indica-
tor is shown on the instrument cluster dis-
play, the GSI is advising the driver to engage
a higher gear. When the down shift indicator
is shown on the display, the GSI is advising
the driver to engage a lower gear.
The GSI indicator remains illuminated until
the driver changes gear, or the driving condi-
tions return to a situation where changing
gear is not required to improve fuel consump-
tion.

Diesel Particulate Filter (DPF) Messages

This engine meets all required diesel engine
emissions standards. To achieve these emis-
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte-
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the ex-
haust system's catalyst to trap and burn Par-
ticulate Matter (PM) pollutants, with no input
or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
The engine may be switched off even if the
warning light is on: repeated interruptions
of the regeneration process could cause an
early deterioration of engine oil. For this
reason it is always advisable to wait for the
symbol to go off before turning off the
engine, following the instructions above.
Do not complete the DPF regeneration
process when the vehicle is stopped.
