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
exhaust system’s catalyst to trap and burn
Particulate 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!
Always drive at a speed appropriate to the
traffic conditions, the weather and traffic
regulations. 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.

— Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel
consumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom
-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Moni -
toring System (TPMS) that illuminates a low
tire pressure warning light when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
warning light illuminates, you should stop
and check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approx
-
imately one minute and then remain continu -
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

CAUTION!
Do not continue driving with one or more
flat tires as handling may be
compromised. Stop the vehicle, avoiding
sharp braking and steering. If a tire
puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

ONBOARD DIAGNOSTIC
SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II.
This system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern -
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag -
nostic codes and other information to assist
your service technician in making repairs.
